糖蜜尿素营养舔块成型及质量参数的影响研究

针对营养舔块在反刍家畜生产尤其是高原草地畜牧业生产中的迫切需要,对糖蜜尿素营养舔块的成型及质量参数进行了研究。结果表明:压制糖蜜尿素营养舔块时,适宜的制作压强为2MPa,较适宜的固化时间为72～96h,且营养舔块固化剂中膨润土与水泥组成比为20%:10%时效果最好。营养舔块的成型及质量还受其组分中糖蜜、麦麸、尿素等因素的影响,通过本试验研究结果表明:糖蜜尿素营养舔块中糖蜜、麦麸、尿素的适宜添加水平分别为20%、4%、10%时,营养舔块的成型及质量均表现为良好,即其配方为:糖蜜20%,尿素10%,食盐10%,玉米粉14%,菜籽粕6%,麦麸4%,石粉3%,固化剂30%(膨润土20%、水泥10%),预混料3%。     

牛羊复合营养舔块饲料适宜配方筛选的研究

通过原料配方试验和牛羊舔食量试验,研究了舔块原料配比、粘合剂种类、调质方法等对压制法生产舔块质量的影响,以及舔块硬度与牛羊舔食量的关系。研究证明,膨润土和生石灰是制备舔块饲料的良好粘合剂和固化剂,糖蜜对于提高舔块的硬度具有明显效果。某些通气性好的饼粕类有助于改善舔块压制过程的排气状况,提高舔块压制的质量。蒸汽直接对物料加热调质不利于提高舔块压制的质量。矿物盐舔块硬度对牛羊舔食量没有明显影响,但高蛋白舔块硬度影响舔食量。硬度越软,舔食量越大。

Organic diseases mimicking acral lick dermatitis in six dogs

Acral lick dermatitis ("lick granuloma") in dogs is often thought to have a behavioral etiology. However, other diseases may cause lesions on the distal legs, mimicking acral lick dermatitis. In this report, six dogs were presented with acral lick dermatitis-like lesions from different underlying causes-namely lymphoma, an orthopedic pin, deep pyoderma, mast cell tumor, leishmaniasis, and (presumptive) sporotrichosis.     

Influence on a North‐Eastern Sandy Highveld sward of winter utilization by sheep

North‐Eastern Sandy Highveld was utilized selectively by sheep grazing alone in winter with a supplementary lick. Winter utilization in four consecutive years had no detrimental effect on production, cover or seed production but care should be exercised in recommending this practice because of the tendency to start “winter” grazing in the critical autumn months and to continue grazing into spring.     

The effect of stocking rate and lick supplementation on the performance of lactating beef cows and its impact on Highland Sourveld

Abstract

The Highland Sourveld of Natal is an important beef producing area. Although it covers only 13% of the total area of the province, it supports 18% of the beef cattle population.

The performance of cows and their calves stocked at four stocking rates on Highland Sourveld was studied. Two stocking rates were duplicated to test the benefit of an energy lick against a mineral lick. The effect of stocking rate on the veld was monitored in terms of compositional change.

Stocking rate significantly affected cow performance and consequently calf performance. An energy lick supplement, as opposed to a mineral lick supplement, was beneficial at the 1,0 LSU/ha stocking rate, but not at the 1,67 LSU/ha stocking rate.

The composition of the veld in the low to moderately stocked treatments changed relatively little, over the recording period, whilst the very high stocking rate treatments showed a rapid delcine in veld composition score.     

Bone, blood and faecal response to an acidogenic lick for range cattle using different concentrations of ammonium chloride

Thirty Brahman-Angus cross heifers at breeding age on extensive grazing were used to test the effectiveness of NH4Cl as an acidogenic agent at 15,18, 21 and 26 % of a dicalcium phosphate lick (A+), compared to a lick of 5 parts dicalcium phosphate and 3 parts salt (A-). Blood and faecal phosphorus (P), faecal calcium (Ca) and faecal magnesium (Mg) were significantly (P<0.05) higher in A+ compared to A-animals at different stages of the experiment. Bone P did not increase in response to NH4Cl but bone Ca was significantly (P<0.05) higher in A+ animals offered 18% NH4Cl and significantly (P<0.05) lower at 15 and 26%. Bone Mg in A+ animals was significantly (P<0.05) higher at 15 and 18% NH4Cl and lower at 26% NH4Cl compared to A- animals. Percentage ash in bone increased linearly from 62.5 to 64.9% in A+ animals as NH4Cl was increased in the lick from 15 to 21% and then decreased to 63.3% but was significantly (P<0.05) greater than the percentage ash in A-animals when the NH4Cl was increased to 26%. Bone mineral status was only marginally improved by adding NH4Cl to the lick in this study but blood P was significantly (P<0.05) improved in A+ compared to A- animals when the lick contained 15, 21 and 26% NH4Cl. Based on bone mineral results reported here, it is recommended that, when NH4Cl is used as an acidogenic agent in licks for range cattle, the amount in the lick should not exceed 21%.     

Phosphorus supplementation of cattle

Severe lameness in a large proportion of an Angus cattle herd was attributed to phosphorus deficiency. The diagnosis was supported by a rapid response to phosphorus supplementation of the diet. A brief review of the development and diagnosis of phosphorus deficiency is presented. Practical considerations severely limit the choice of a phosphorus supplement. Directions for the use of the supernatant of high-phosphorus fertiliser and water mixtures, as feed or stock water additive and the production of a phosphorus lick are described. Other phosphorus supplements are discussed with particular reference to the fluorine hazard.     

Bone mineral response to ammonium sulphate offered as a lick supplement in beef calves

Sixteen Bonsmara calves (4 males, 12 females) between 10 and 18 months of age were blocked according to age and sex and randomly assigned to 2 groups. They were offered licks containing bone meal and salt (50:50 ratio) (control) and bone meal and ammonium sulphate (NH4SO4) at 1.25, 2.5, 5, 10, 15, and 18% (treatment) to evaluate the effects of dietary anions on bone phosphate (P) concentration. Bone P concentration was significantly (P < 0.05) higher in the NH4SO4 group compared with the control group, indicating that NH4SO4 was able to increase the P content of bone at each of the 6 concentrations used in the lick relative to the control animals, thereby improving the P status of the animals. Ammonium sulphate at 15% and 18 % in the lick also significantly (P < 0.05) increased bone P compared with the lower concentrations of NH4SO4. Bone calcium (Ca) fluctuated as a result of the acidogenic lick. There was absorption of Ca when P was being resorbed and resorption of Ca when P was being absorbed into and out of bone. Bone Ca:P ratio ranged from 3.2 to 6.4 among the control group and 1.6 to 4.3 among the treatment group. Animals receiving the acidogenic lick had a higher percentage ash compared to the control group for most of the experimental period. Bone magnesium (Mg) fluctuated in response to the acidogenic lick, and it was difficult to show a relationship between bone Mg and Ca or P. The overall mean cortical bone thickness was significantly (P < 0.05) greater in treatment (1.60 mm) compared with control (1.43 mm) calves and this was also true at sampling periods 2, 4, 5 and 6. Bone thickness followed bone P and not bone Ca. Results from this research indicate that the addition of ammonium sulphate to a lick had a beneficial effect in improving the P status by increasing bone P and improving the mineral status of bone by increasing the thickness of cortical bone and percentage ash.
