Influence of Dietary Isoflavonoids on Stability of Egg Yolk Lipids

An experiment was conducted to investigate the influence of dietary tea polyphenol (TP) and daidzein (DA) on lipid stability of egg yolk. Two-hundred and seventy 27-week-old Hisex Brown laying hens were divided into nine groups, fed a diet supplemented with 0, 5, 10, 20, 40 mg kg-1 TP and 5, 10, 20, 40 mg kg- 1 DA respectively for a period of 8 weeks ad libitum. The dietary addition of TP and DA both could reduce egg yolk LPO content significantly at the end of 4-week experiment (P ＜ 0.05) and keep egg yolk lipid stable at the supplemental dose of 10 mg kg- 1 diet respectively. A significant liner reduction in egg yolk LPO content was found with the increasing of dietary TP and DA. The egg yolk LPO content was decreased by 23.1 and 27.0% (P＜ 0.05) with the supplementation of TP and DA respectively at 40 mg kg-1 diet. The LPO contents in liver, plasma and egg yolk were decreased significantly with the dietary addition of TP or DA respectively ( P ＜ 0.05). There was no significant difference between the effects of TP and DA on improvement of layers‘ antioxidative capacity. The dietary TP and DA both could improve the bird‘s antioxidative level directly irrelevant to SOD and GSH-Px actiVities.     

Fatty Acid Accumulation in Seeds of Three Seed Pumpkin Cultivars

In the literature there are many reports on the composition and properties of pumpkin seed oil; however, few is known about the effect of different stages of seed development on various fatty acid profiles in developing seeds. The objective of this study was to provide the changes of various fatty acid accumulations in seed oil obtained from the seeds of three pumpkin varieties belonging to the species Cucurbita maxima and Cucurbita pepo. Unsaturated acids (oleic and linoleic) were dominant in various fatty acids, which constituted 38.9%-49.1% and 29.4%-42.7% of the total fatty acids at seed maturity for three pumpkin varieties, respectively, while other fatty acid concentrations except for palmitic acid all did not reach 10%. Different varieties exhibited greater effect on various fatty acid contents and the total fatty acid contents in the seeds of pumpkin rather than the species. On the whole, palmitic acid profiles of the seed oil in three varieties all followed the fluctuant decrease during all the stages of seed development, but palmitoleic acid and the total fatty acid profiles of the seed oil in three varieties were just the opposite. Stearic, oleic and linoleic acid profiles of the seed oil in three varieties all experienced the third pattern that fluctuated during all the stages of seed development, but no significant differences in these three fatty acid concentrations were found from the beginning to the end. Linolenic acid concentrations of three varieties were on the decline and ultimately close to zero. Myristic and arachidic acid profiles of the seed oil followed different trends in three varieties. Among them, myristic and arachidic acid profiles of the seed oil of Yinhui-1 fluctuated downward all the time until seed maturity, but those of 0238-1 and Jinhui-2 completely changed oppositely.     

Effects of Pawpaw Seed Powder as an Additive on Growth of Catfish Fingerlings Reared in an Indoor Tanks

Since the demand of African Catfish (Clarias gariepinus) is on increase there is need to increase its production so as to meet the protein requirement of the populace. An investigation was conducted for six weeks feeding trial to determine the performance of African catfish (Clarias gariepinus) fingerlings feed diets containing varying replacement level of fish meal with pawpaw seed powder meal (Carica papaya). Fingerlings of Clarias gariepinus were subjected to five different dietary treatments with varying levels of pawpaw seed powder meal. The diets I-V contained 0, 20%, 40%, 60% and 80% replacement levels, respectively. The experiment was carried out in an 80 litres circular plastic bowls, the treatments were in triplicate. Each bowl contained 12 fingerlings. Feeding was done at 3% body weight per day and fishes were weighed every week. Growth parameters such as specific growth rate (SGR), weight gained (WG), food conversion ratio (FCR), protein efficiency ratio (PER) and mortality were determined. Therefore, it could be concluded that fish meal could be replaced up to 80% with pawpaw seed powder meal in the diet of Clarias gariepinus fingerlings to encourage growth, while at 40% pawpaw seed powder meal inclusion mortality was reduced.     

Dietary Supplementation of Oregano and Sage Dried Leaves on Performances and Meat Quality of Rabbits

The aim of this research was to evaluate the dietary supplementation 1% （w/w） of oregano and sage dried leaves on performances and meat quality of broiler rabbits. A feeding trial, which lasted 48 d, was carried out on 105 male Bianca Italiana rabbits randomly divided in seven groups and fed ad libitum. At the end of the trial ten animals per group were slaughtered and samples of dorsal muscle were taken in order to perform laboratory analysis. Mortality rate did not statistically differ between groups. Growth performances of animals fed diets supplemented with aromatic plants were higher （P〈0.05） than those of animals of control group, whereas carcass parameters were not affected by treatments excepting for the slaughter weight that showed the same trend as growth performances. Meat quality traits, oxidative lipid stability and fatty acid proifle were not inlfuenced by aromatic plant supplementation. In conclusion, oregano and sage in form of dried leaves can be used in rabbit without adverse effects on performance, carcass characteristics and meat quality traits.     

Effect of Wood Vinegar on Seed Germination and Water Implantation of Corn

To analyze the effect of wood vinegar on seed germination and seedling growth, the seeds of corn are dipped in wood vinegar of different densities. The results showed that significant effects were found through all the treatments on the seed germination rate, the seed germinating energy and the germinating index. The regress CUBICS curves were developed to describe the relation. The reasonable parameters range was obtained. At the same time, the corn was cultivated by wood vinegar of different densities, aiming to study the effect of wood vinegar on biomass. It showed that all treatments had obvious effects on the seedling length and dry weight aboveground, the chlorophyll and dry weight underground were not included. The research results could be used to direct the wood vinegar deeply refining process and product development.     

Performance of Fatty Liver Development in Response to Brown Rice and Corn-Based Diets in Overfed Landes Geese （Anser anser）

The effect of brown rice and corn-based diets on fatty liver weight, carcass traits, lipids accumulation and liver composition of Landes geese (Anser anser) after feeding the same amount of each diet was investigated. After 2 weeks overfeeding,besides body weight and body weight gain increased significantly, the fatty liver weights were increased dramatically from 94.67 to 554.67 and 754.00 g in corn treatment and rice treatment, respectively, and the accumulation lipids in adipose tissues reached up to or close to 2 folds of initial weight in both treatments. Liver weight was greater in brown rice group than in corn group (P＜0.05). Compared to before overfeeding, triacylglycerols (TG) in geese fatty liver increased dramatically and predominated (from 9.08% to close to or more than 90% of hepatic lipids), whereas phospholipids (PL) and cholesteryl esters (CE) decreased sharply in both treatments (P＜O.05). However, the percentages of lipids, TG and PL in fatty liver were higher in brown rice treatment than in corn treatment, and that of CE was lower (P＜O.05). It indicates that overfeeding chiefly results in lipids accumulation in goose fatty liver and adipose tissues. Brown rice-based diet induces greater fatty liver, and brown rice is one of high quality overfeeding ingredients instead of corn.     

Effects of Tebufenozide on the Biological Characteristics of Beet Armyworm （Spodoptera exigua Hǖbner） and Its Resistance Selection

In this article, the selection of tebufenozide to beet armyworm （Spodoptera exigua Htibner） was studied by the treatments to alternative generations＇ 3rd-instar larvae with LC50 dose and to continuous generations＇ larvae with LC10 dose; the effects of tebufenozide on the biological characteristics of current and subsequent generations were examined by the treatments to 3rd-instar larvae and egg pods in different concentrations. After treatments with LC50 dose till F11, the toxicity of tebufenozide to beet armyworm had no significant change, whereas the pupation rate, pupal weight, and fecundity were reduced markedly. After treatments with LC10 dose till Fl9, the beet armyworm only developed 3.52-fold resistance, and the main biological characteristics were nearly accordant in each generation. The livability was reduced 72 h later after treatments to 3rd-instar larvae, respectively in 2.5-40 μg mL^-1, and larval duration, pupation rate, and pupal weight changed considerably with the increase in concentrations. The fecundity, larval livability, larval weight and pupal weight of subsequent generations were reduced as the dose increased over 10 μg mL^-1. The hatching rate of egg pods did not differ with that of the controls obviously after treatment in 10-300 μg mL^-1. But the larval livability, larval weight and pupal weight were reduced when eggs were exposed to 50 μg mL^-1 dose or more. The results indicated that tebufenozide had low resistance risk to the current and subsequent generations of beet armyworm even if tebufenozide had significant effects on the biological characteristics of this insect.     

Effects of Lanthanum and Cerium on Seeds Fatty Acid Composition in Soybean

Soybean Dongnong 42 from northeast of China was used as an experimental material. The samples were tested by spraying different concentrations of LaCl3, CeCl3 and LaCl3+CeCl3 solutions on the leaves at the seedling stage and the early flowering stage of the soybeans. Gas chromatography was used to determine the fatty acid content and ratio of the soybean seeds at the maturity stage. The fatty acid ratio of soybean seeds were evaluated by calculating saturated fatty acid(SFA), monounsaturated fatty acid(MUFA), polyunsaturated fatty acid(PUFA), unsaturated fatty acids(UFA), UFA/SFA, index unsaturated fatty acid(IUFA) and double bond index(DBI).(MUFA+PUFA)/SFA was used to study the effects of rare earths on the quality of soybean seeds. The results showed that spraying the rare earth solution could significantly optimize the fatty acid distribution ratio of soybean seeds. Compared with the control group(CK), stearic acid was reduced by 5% and linolenic acid was reduced by 3.72%. Except for La10, the oleic acid content increased significantly by 2.22%. Under the treatment of 30 mg·L~(-1) CeCl_3, UFA, UFA/SFA and DBI were 83.56, 5.08 and 9.47, respectively, which were the highest in each group. Under the treatment of 150 mg·L~(-1) LaCl_3,(MUFA+PUFA)/SFA was 4.89, the closest meal to the recommended ratio. The above results showed that spraying appropriate concentrations of rare earth at the seedling stage and the early flowering stage could optimize the fatty acid ratio of soybean seeds and improve dietary fatty acid ratios.     

Response of Element Distribution of Various Organs of Maize to Fertilizer Application

The effect of fertilizer application on biomass dry weight and element distribution of various organs of maize was investigated from the aspect of microscopic view to disclose the internal mechanism of fertilizer effect on crop. Five fertilizer treatments： no fertilizer （CK）, nitrogen phosphorus fertilizer （NP）, nitrogen potassium fertilizer （NK）, phosphorus potassium （PK）, and nitrogen phosphorus potassium fertilizer （NPK） were designed. Field experiment on the response of biomass dry weight and N, P, K, Cu, Zn, Fe, and Mn element distribution of stem, leaf and seed of maize （Zea mays L.） to different fertilizer treatments application was carried out. The results showed that dry weight and element content of various organs of maize were different. N content of various organs followed this order leaf〉 seed 〉 stem; P content of various organs was seed 〉 leaf〉 stem; K content was stem 〉 leaf〉 seed; and Fe content was leaf〉 stem 〉 seed. Fertilizer application reduced the differences of N, P, K, and Fe contents of various organs, and changed the size order of the dry weight and the Cu and Zn contents of leaf, seed and stem. Except for individual treatment, the response direction of N, P and Fe elements to fertilizer application was similar to Cu and Zn. The response of element content of various organs of maize to different fertilizer combinations was also different. The response extent of N, P and K major elements to fertilizer application was larger than microelement of Cu, Zn, Fe, and Mn; the response extent of stem and leaf was larger than seed; the response to NPK fertilizer treatment was bigger than NP, NK and PK. In the whole, response differences of element distribution to various fertilizer treatments were not remarkable. Besides, element distribution of various organs of maize was also influenced by the mutual effect of fertilizer varieties. The response direction and extent of various element distributions to different fertilizer treatments had both similarities and differences. Adjusting fertilizer application could change the biomass dry weight and element distribution of various organs of maize, thus promote the uptake and cycle of nutrient. This investigation could provide useful information for high production.     

Sunflower response to potassium fertilization and nutrient requirement estimation

Field experiments were conducted in oil and edible sunflower to study the effects of potassium(K) fertilization on achene yield and quality, and to estimate the nutrient internal efficiency(IE) and nutrient requirement in sunflower production. All trials in edible sunflower and 75% trials in oil sunflower showed positive yield responses to K fertilization. Compared with control without K fertilization, the application of K increased achene yield by an average of 406 kg ha~(–1) for oil sunflower and 294 kg ha~(–1) for edible sunflower. K application also increased 1 000-achene weight and kernel rate of both oil and edible sunflower. K fertilization improved the contents of oil, oleic acid, linoleic acid and linolenic acid in achenes of oil sunflower, and increased contents of oil, total unsaturated fatty acid and protein in achenes of edible sunflower. The average agronomic efficiency of K fertilizer was 4.0 for oil sunflower and 3.0 kg achene kg~(–1) K_2O for edible sunflower. The average IE of N, P and K under balanced NPK fertilization was 22.9, 82.8, and 9.9 kg kg~(–1) for oil sunflower, and 27.3, 138.9, and 14.3 kg kg~(–1) for edible sunflower. These values were equivalent to 45.5, 14.1, and 108.1 kg, and 39.0, 8.0, and 71.7 kg of N, P and K, respectively, in above-ground dry matter required for production per ton of achenes. The average harvest index of N, P and K was 0.47, 0.56 and 0.05 kg kg~(–1) in oil sunflower, and 0.58, 0.58 and 0.14 kg kg~(–1) in edible sunflower.     

The Effect of Dietary Vegetable Oilseeds Supplement on Fatty Acid Profiles in Milk Fat from Lactating Dairy Cows

To determine the effect of dietary supplementation with vegetable oilseeds on the composition of bovine milk fatty acids （FAs）, 40 Holstein dairy cows were used with a complete randomized design. At the beginning of the experiment, the cows were 150±25 day in milk （DIM）. Total duration of the experiment was six weeks. Measurements were made during the last three weeks. Cows in four treatments were fed with a basal diet （CT） or basal diet supplemented with either whole full fat soybean （WFS）, full fat expanded soybean （FPS） or whole full fat soybean with whole cottonseed and full fat expanded soybean （MIX）. The composition of the milk fat was analyzed by gas chromatography. Relative to control, the conjugated linoleic acid （CLA） concentration in milk fat from cows on FPS was significantly increased by 83.88% （P〈 0.05）. The proportions of C12：0 were decreased by 35.7, 35.51, and 38.65% in milk fat from cows on WFS, MIX, and FPS compared with cows on CT. Similar decreases in C 14：0 were 23.83, 24.85, and 31.48% in WFS, MIX, and FPS treatments, respectively. Feeding vegetable oilseeds increased the proportion of healthy FAs （mainly CLA）, whereas decreased the concentratiofi of C12：0 and C14：0. Therefore, milk and dairy products would have higher nutritive and therapeutic value.     

Effects of Fermentation Product Containing Phytase on Productive Performance,Egg Quality,and Phosphorous Apparent Metabolism of Laying Hens Fed Different Levels of Phosphorus

This study investigated the effects of fermentation product containing phytase （FPP） that was fermented using waste vinegar residue （WVR） as substrate from Aspergillusficuum NTG-23 on productive performance, egg quality, and phosphorus apparent metabolism of laying hens. First, 375 22-wk-old Jinghong hens were allocated into 5 treatments （5 replicates of 15 hens each） in an 8-wk experiment for evaluating the parameters of productive performance, egg quality, serum, and tibia. Experimental diets contained 4% FPP and 96% corn-soybean diet. The levels of dicalciurn phosphate （DCP） were 1.34, 1.01, 0.67, 0.34 and 0%. Next, thirty 31-wk-old Jinghong hens were fed 5 types of diets for evaluating phosphorous apparent metabolism rate. Egg productive rate, egg weight, feed conversion ratio, Haugh unit, egg albumen height, serum calcium, tibia ash, tibia ash calcium and tibia breaking strength were not different significantly among 5 treatments. The significant difference of average daily feed intake was not appeared when the DCP content of corn-soybean-FPP diet was reduced to 0.67%; the eggshell hardness, eggshell thickness and serum phosphorus were not reduced significantly until the DCP content of corn-soybean-FPP diet was reduced to 0.34%. The yolk color was improved when the laying hens fed deficient DCP corn-soybean-FPP diet. A 22.14% reduction in excreta phosphorus was observed when the laying hens fed low phosphorus （0.67% DCP） corn-soybean-FPP diet. A 30% elevation of phosphorus apparent metabolism rate was obtained when the DCP content of corn-soybean-FPP diet was decreased from 1.34 to 1.01%. The reducing cost of layer diet was totalized about 120 CNY 1000 kg1 diet when the content of DCP was 0.67% in corn-soybean-FPP diet. These results indicated that FPP could be applied in laying hen as a potential, cost-effective and rational application of WVR.

Effects of UV-B Radiation and Water Stress on Soybean Yield

Soybean Dongnong 47 was subjected to the experiments of increasing UV-B radiation and water stress on soybean yield components in different growth periods. The results showed that 100-seed weight greatly increased during the early stage of pod filling in the treatment of weak UV-B radiation, seed number per plant as well as seed weight per plant and Dongnong47 yield also increased, while the yield and yield components of Dongnong47 during the blossom to mature period were negatively affected in the treatment of intensive UV-B radiation. 100-seed weight of Dongnong47 all increased in the double factor treatments of UV-B radiation and water stress, with the drought intensified, seed number per plant, seed weight per plant and yield of Dongnong47 decreased, the change of 100-seed weight were various and the antagonistic action of UV-B radiation and water stress were related with their intensity.     

Some Engineering Properties of Sunflower Seed and Its Kernel

Some engineering properties of sunflower seed and its kernel, Shahroodi variety as a case study, were investigated at various moisture content levels （3-14% d.b.） for three size categories （large, medium and small）. With increase of moisture content from 3 to 14% d.b., all the main dimensions （length, width and thickness）, geometric mean diameter, porosity, true density, terminal velocity and static coefficient of friction increased while bulk density and rupture force for both sunflower seed and its kernel decreased for all size categories. The results showed that the highest value of static coefficient of friction for both seed and kernel was on the rubber surface, followed by plywood, polyethylene, galvanized iron, and finally aluminium surfaces. The seeds required less compressive force to dehull when loaded under the horizontal as compared to the vertical orientation. But for kernels, the trend was the opposite. Also, the compressive forces needed to initiate rupture of sunflower seed hulls were higher （47.1-94.72 N） than those required to rupture the kernel （8.5-13.4 N） in both orientations.     

Nitrogen spraying affects seed Bt toxin concentration and yield in Bt cotton

Cotton bolls exhibit the lowest insecticidal efficacy among all organs of Bt cotton, which would ultimately affect the yield formation. The objective of this study was to investigate the effects of different urea concentrations on the seed Bt protein contents, seed cotton yield and the corresponding protein metabolism mechanism. The experiments were conducted during 2017–2018 cotton growing seasons. Two cultivars, Sikang 3(hybrid, SK3) and Sikang 1(conventional, SK1), were treated with six urea concentrations and their seed Bt protein contents were compared during boll formation period. The urea spray concentration had a significant effect on the seed Bt toxin content and seed cotton yield. Spraying of either 5 or 6% urea led to higher insecticidal protein contents and higher seed cotton yield for both cultivars. Moreover, the highest amino acid and soluble protein contents, as well as GPT and GOT activities, and lower protease and peptidase activities were observed at the 5 to 6% urea levels. Significant positive correlations between the seed Bt toxin and amino acid contents, and between the seed Bt toxin content and GPT activities were detected. The lower boll worm number and hazard boll rate were also observed with the 5 to 6% urea treatments, which may be the reason why nitrogen spraying increased the seed cotton yield. Therefore, our results suggested that the seed Bt toxin content and insect resistance were impacted markedly by external nitrogen application, and 5 to 6% urea had the greatest effect on insect resistance.     

Effect of Different Treatment Rapeseeds on Activity of Cellulose Enzyme in Sheep

The purpose of the experiment is to research the effect of different rapeseed treatments feeding on activity of cellulose enzyme in sheep. Eight male adults of semi-fine wool sheep breeds with the same weight and permanent rumen cannulas were selected according to 4×4 Latin square design to determine the effect of different rapeseed treatment groups including crushed rapeseed, whole rapeseed, extruded rapeseed (dietary lipid content of =67 g · kg-1 ) and control group (dietary lipid content of =30 g · kg-1 ) on activity dynamic variation of ruminal celluolytic enzyme in sheep. The results showed that ruminal fluid pH matched up to the condition of fiber degradation and growth of cellulolytic bacterium when fed four diets; but there was significant difference (P0.05) for the activity of microcrystalline cellulose, glucanase, salicin enzyme involved in ruminal fiber degradation after fed 2, 4, 6 h.     

Impacts of the unsaturation degree of long-chain fatty acids on the volatile fatty acid profiles of rumen microbial fermentation in goats in vitro

This study investigated the impacts of the degree of unsaturation(unsaturity) of long-chain fatty acids on volatile fatty acid(VFA) profiles of rumen fermentation in vitro. Six types of long-chain fatty acids, including stearic acid(C18:0, control group), oleic acid(C18:1, n-9), linoleic acid(C18:2, n-6), α-linolenic acid(C18:3, n-3), arachidonic acid(C20:4, n-6) and eicosapentaenoic acid(C20:5, n-3), were tested. Rumen fluid from three goats fitted with ruminal fistulae was used as inoculum and the inclusion rate of long-chain fatty acid was at 3%(w/w) of substrate. Samples were taken for VFA analysis at 0, 3, 6, 9, 12, 18 and 24 h of incubation, respectively. The analysis showed that there were significant differences in the total VFA among treatments, sampling time points, and treatment×time point interactions(P0.01). α-Linolenic acid had the highest total VFA(P0.01) among different long-chain fatty acids tested. The molar proportion of acetate in total VFA significantly differed among treatments(P0.01) and sampling time points(P0.01), but not treatment×time point interactions(P0.05). In contrast, the molar proportion of propionate did not differ among treatments during the whole incubation(P0.05). However, for butyrate molar proportions, significant differences were found not only among sampling time points but also among treatments and treatment×time point interactions(P0.01), with eicosapentaenoic acid having the highest value(P0.01). Additionally, no statistically significant differences were found in the acetate to propionate ratios among treatments groups(P0.05), even the treatments stearic acid and α-linolenic acid were numerically higher than the others. The inclusion of 3% long-chain unsaturated fatty acids differing in the degree of unsaturation brought out a significant quadratic regression relation between the total VFA concentration and the double bond number of fatty acid. In conclusion, the α-linolenic acid with 3 double bonds appeared better for improving rumen microbial fermentation and the total VFA concentration.

Seed Priming Influence on Early Crop Growth,Phenological Development and Yield Performance of Linola (Linum usitatissimum L.)

Reduced early crop growth and limited branching are amongst yield limiting factors of linola. Field response of seed priming treatments viz. 50 mmol L^-1 salicylic acid （SA）, 2.2% CaCl2 and 3.3% moringa leaf extract （MLE） including untreated dry and hydropriming controls was evaluated on early crop growth and yield performance of linola. Osmopriming with CaCl2 reduced emergence time and produced the highest seedling fresh and dry weights including Chl. a contents. Osmopriming with CaCl2 reduced crop branching and flowering and maturity times and had the maximum plant height, number of branches, tillers, pods and seeds per pod followed by MLE. Increase in seed weight, biological and seed yields was 9.30, 34.16 and 39.49%, harvest index （4.12%） and oil contents （13.39%） for CaCl2 osmopriming. Positive relationship between emergence and seedling vigor traits, 100-seed weight, seed yield with maturity time, 100-seed weight and seed yield were found. The study concludes that seed osmopriming with CaC12 or MLE can play significant role to improve early crop growth and seed yields of linola.
