枯草芽孢杆菌、酿酒酵母及其复合菌发酵棉粕营养成分变化的研究

试验旨在研究枯草芽孢杆菌、酿酒酵母及其复合菌发酵棉粕的常规营养成分、棉籽肽含量及棉籽肽分子质量分布的变化。试验设4个组：对照组（未发酵组）、试验Ⅰ组（枯草芽孢杆菌-1）、试验Ⅱ组（酿酒酵母）及试验Ⅲ组（枯草芽孢杆菌-1和酿酒酵母复合发酵）。检测各组棉粕样品粗蛋白质（CP）、干物质（DM）、粗灰分（Ash）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）、粗脂肪（EE）、钙（Ca）、磷（P）、棉籽肽含量和棉籽肽分子质量分布等指标。结果表明：①试验Ⅰ组DM、CP和Ash含量极显著高于其他处理组 （P < 0.01）;对照组EE含量显著高于其他处理组 （P < 0.01）;试验Ⅲ组ADF含量极显著低于其他处理组（P < 0.01）;3个试验组Ca和P含量较对照组均有所提高,其中试验Ⅲ组Ca和P含量显著高于对照组（P < 0.05）。②各试验组之间游离氨基酸和总游离氨基酸含量差异均不显著（P > 0.05）,但与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组总游离氨基酸含量分别提高了134.02%、75.59%和75.44%;③各试验组酸溶蛋白质和棉籽肽含量均极显著高于对照组（P < 0.01）,其中试验Ⅰ组的酸溶蛋白质和棉籽肽含量最高;3个发酵试验组1 000 u以下的棉籽肽峰面积百分比分别为89.41%、77.61%和84.58%。综合以上试验结果,在枯草芽孢杆菌、酿酒酵母及其复合菌的作用下,通过固态发酵能显著改善棉粕的营养价值,为棉粕资源的开发利用提供了理论依据。

Effects of histamine antagonists, an anticholinergic agent and antacid on gizzard erosions in broiler chicks

The effects of histamine antagonists, an anticholinergic agent and antacid on gizzard erosion (GE) induced by heated casein-histidine mixture (h-CH), histamine or starvation were examined. Diphenhydramine, an H1-antagonist, had no effect on the GE formation caused by h-CH, but reduced the severity of the lesions induced by histamine and starvation. Cimetidine, an H2-antagonist, blocked completely the formation of the lesions induced by h-CH or histamine but did not prevent starvation-induced GE. Gastric antacid decreased the severity of GE caused by h-CH and histamine. The formation of GE by starvation was blocked by the administration of propantheline bromide or inert solids. The results suggest that the stimulated gastric secretion caused by the H2-activity of h-CH or histamine is largely responsible for the formation of GE. In starvation-induced GE, however, alteration of gastric secretion had no effect on the formation of the lesion as it was caused by the emptiness of the gizzard.     

Near Infrared Reflectance Spectroscopy for the Determination of Free Gossypol in Cottonseed Meal

Gossypol is a toxic polyphenolic compound produced by the pigment glands of the cotton plant. The free gossypol content of cottonseed meal (CSM) is commonly determined by the American Oil Chemists’ Society (AOCS) wet chemistry method. The AOCS method, however, is laboratory-intensive, time-consuming, and therefore, not practical for quick field analyses. To determine if the free gossypol content of CSM could be predicted by near infrared reflectance spectroscopy (NIRS), CSM samples were collected from all over the world. All CSM samples were ground and a portion of each analyzed for free gossypol by the AOCS procedure (reference data) and by NIRS (reflectance data). Both reflectance and reference data were combined in a calibration. The coefficient of determination (r²) and standard error of prediction (SEP) were used to assess the calibration accuracy. The r² was 0.728, and the SEP was 0.034 for the initial calibration that included samples from all over the world. However, the r² and SEP improved to 0.921 and 0.014, respectively, if the calibration was made using CSM samples only from the United States. These results indicate that a general prediction equation can be developed to predict the free gossypol content of CSM by NIRS. From a practical standpoint, NIRS technology provides a method for quickly assessing whether a particular batch of CSM has a free gossypol content low enough to be suitable for use in poultry diets.

棉籽壳作为绵羊饲料营养特性的研究

通过消化代谢试验研究绵羊对棉籽壳(含仁棉籽壳、无仁棉籽壳)和粉碎玉米秸秆的自由采食量和表观消化率,旨在对棉籽壳的营养价值和消化特点进行评价.试验选择12只成年新疆美利奴公羊,随机分为2组(n=6),在饲喂300 g/(只·d)混合精料的基础上分别喂给400(试验1组)、800(试验2组)g/(只·d)无仁棉籽壳,用差数法测定绵羊对棉籽壳的表观消化率.另外,选择18只成年新疆美利奴公羊,随机分为3组(n=6),在饲喂300 g/(只·d)混合精料的基础上,分别自由采食含仁棉籽壳(试验3组)、无仁棉籽壳(试验4组)和粉碎玉米秸秆(试验5组),研究绵羊对其的消化代谢情况.结果表明,绵羊对无仁棉籽壳干物质、有机物、粗蛋白质、纤维素、半纤维素和能量的表观消化率分别为46.71%、47.37%、-53.40%、66.60%、62.48%和42.59%.饲喂含仁棉籽壳、无仁棉籽壳和粉碎玉米秸秆时,饲喂含仁和无仁棉籽壳组的干物质、有机物、纤维素、半纤维素、能量和钙等的采食量均无明显差异(P> 0.05),但采食含仁棉籽壳组粗蛋白质和磷的采食量极显著高于无仁棉籽壳组(P< 0.01),木质素采食量极显著低于无仁棉籽壳组(P< 0.01).饲喂含仁棉籽壳日粮和无仁棉籽壳日粮绵羊间干物质、有机物和能量的表观消化率均无明显差异(P> 0.05),但无仁棉籽壳组绵羊的纤维素和半纤维素的表观消化率却分别显著和极显著高于含仁棉籽壳组(P< 0.05;P< 0.05),含仁棉籽壳组粗蛋白质的表观消化率极显著高于无仁棉籽壳组(P< 0.01);饲喂玉米秸秆时绵羊的干物质、有机物、粗蛋白质、纤维素和能量的表观消化率均极显著高于饲喂含仁或无仁棉籽壳的绵羊(P< 0.01),但钙和磷的表观消化率却低于饲喂棉籽壳的绵羊(P> 0.05).饲喂含仁棉籽壳日粮绵羊的氮摄入量和氮保留率极显著高于无仁棉籽壳日粮绵羊(P< 0.01);饲喂玉米秸秆日粮绵羊和饲喂无仁棉籽壳绵羊在氮保留上无明显差异(P> 0.05).因此,棉籽壳是一种特殊的粗饲料,绵羊对其采食量大,纤维素类物质和能量的消化率较高,但存在着严重的蛋白质消化障碍;无仁棉籽壳日粮与玉米秸秆日粮的营养价值基本相当,但绵羊对无仁棉籽壳日粮的氮消化率较低.     

Study on Nutritional Characteristics of Cottonseed Hull as a Feed of Sheep

In this paper through digestive and metabolic experiments studied the voluntary intake and apparent digestibility of cottonseed hulls (kernel-contained CH,kernel-free CH) and cornstalk on sheep to evaluate the nutrition value and digestion characteristics of cottonseed hulls.12 of adult Xinjiang merino rams were selected and divided into two groups (n=6 each group),and on the basis of 300 g/(head·day) of mixed concentrate,fed with kernel-free CH by 400 (group 1) or 800 (group 2) g/(head·day) respectively,to estimate the digestibility of CH by difference method;As well,another 18 of adult Xinjiang merino rams were selected and divided into three groups (n=6 each group),and on the basis of 300 g/(head·day) of mixed concentrate,cafeteria feeding with kernel-contained CH (group 3),kernel-free CH (group 4) or ground cornstalks (group 5) respectively,to study the effects of three diets on the voluntary intake,digestion and metabolism of sheep.The results showed that the apparent digestibility of the DM,OM,CP,cellulose,hemicellulose and energy of kernel-free CH by sheep were 46.71%,47.37%,-53.40%,66.60%,62.48% and 42.59%,respectively.There were no significant differences in the intake of DM,OM,cellulose,hemicellulose,energy and Ca between kernel-contained CH and kernel-free CH groups (P> 0.05);Intake of CP and P in kernel-contained CH group were extremely significantly higher than that in kernel-free CH group (P< 0.01);Intake of lignin in kernel-contained CH group was extremely significantly lower than that in kernel-free CH group (P< 0.01).There were no significant differences in the apparent digestibility of DM,OM and energy between kernel-contained CH and kernel-free CH groups (P> 0.05).The apparent digestibility of cellulose and hemicellulose in kernel-free CH group were significantly and extremely significantly higher than that in kernel-contained CH group (P< 0.05;P< 0.01),respectively.The apparent digestibility of CP in kernel-contained CH group was extremely significantly higher than that in kernel-free CH group (P< 0.01).The apparent digestibility of DM,OM,CP,cellulose and energy in ground cornstalks group were extremely significantly higher than that in kernel-contained CH and kernel-free CH groups (P< 0.01),however,the apparent digestibility of Ca and P were lower than that in kernel-contained CH and kernel-free CH groups (P> 0.05).Intake and retention of nitrogen in kernel-contained CH group were extremely significantly higher than that in kernel-free CH group (P< 0.01);The was no significant difference in the retention of nitrogen between kernel-free diet group and cornstalk diet group (P> 0.05).It was concluded that CH was a kind of special forage with larger intake,higher digestibility on the fiber substances and energy,but with a serious obstruction on protein digestion;The nutritional value between kernel-free diet and cornstalk diet was almost equal,and with lower nitrogen digestibility on kernel-free diet.
