Background： Post-production fractionation of wheat distillers grains with solubles（DDGS） increases their crude protein content and reduces their fiber *** experiment was conducted to determine the effects of fractionation of wheat DDGS on apparent total tract digestibility（ATTD） and performance when fed to broiler chicks（0–21 d）.Methods： A total of 150,day-old,male broiler chicks（Ross-308 line;Lilydale Hatchery,Wynyard,Saskatchewan） weighing an average of 49.6 ± 0.8 g were assigned to one of five dietary treatments in a completely randomized *** control diet was based on wheat and soybean meal and contained 20% regular wheat *** experimental diets contained 5,10,15 or 20% fractionated wheat DDGS added at the expense of regular wheat ***： The ATTD of dry matter and gross energy were linearly increased（P 0.01） as the level of fractionated wheat DDGS in the diet *** retention was unaffected by level of fractionated wheat DDGS（P 0.05）.Weight gain increased linearly（P = 0.05） as the level of fractionated wheat DDGS in the diet *** intake,feed conversion and mortality were unaffected by level of fractionated wheat DDGS in the diet（P 0.05）.Conclusions： Post-production fractionation of wheat DDGS improves their nutritional value by lowering their fiber content and increasing their content of crude protein and *** changes in chemical composition supported increased weight gain of broilers fed wheat DDGS.

Two experiments were conducted to study the effects of red pepper (Capsicum frutescens) powder or red pepper pigment on the performance and egg yolk color of laying hens. In Exp.1, 210, thirty-week old, Hy-line Brown laying hens were fed one of seven diets containing 0.3, 0.6, 1.2, 2.0, 4.8 or 9.6 ppm red pepper pigment or 0.3 ppm carophyll red. Each diet was fed to three replicate batteries of hens with each battery consisting of a row of five cages of hens with two hens per cage (n=3). In Exp. 2, 180, thirty-week old, Hyline Brown laying hens, housed similarly to those in Exp. 1, were fed an unsupplemented basal diet as well as treatments in which the basal diet was supplemented with 0.8% red pepper powder processed in a laboratory blender to an average particle size of 300 μm, 0.8% red pepper powder processed as a super fine powder with a vibrational mill (44 μm) and finally 0.8% red pepper powder processed as a super fine powder with a vibrational mill but mixed with 5% Na 2 CO 3 either before or after grinding. A diet supplemented with 0.3 ppm carophyll red pigment was also included (n=3). In both experiments, hens were fed the red pepper powder or pigment for 14 days. After feeding of the powder or pigment was terminated, all hens were fed the basal diet for eight more days to determine if the dietary treatments had any residual effects. In Exp.1, there were no differences in egg-laying performance, feed consumption or feed conversion ratio due to inclusion of red pepper pigment in the diet. Average egg weight was higher (p0.05). However, compared with the control group, supplementation with all of the red pepper

上期回顾:上一期主要介绍了AGPs替代方案中的抗菌肽和粘土矿物的作用等。3卵黄抗体在感染致病性微生物的情况下,使用卵黄抗体(一般指IgY)似乎是一个很有潜力的替代抗生素生长促进剂的技术方案。为了生产这些抗体,需要给产蛋鸡注射能引发猪特定疾病的致病原。给产蛋鸡注射这些抗原后会诱发免疫反应,产生相应的抗体。这些抗体通常都沉积在卵黄中。加强免疫是为了让抗体不断地沉积到卵黄中。

在过去的20年中,为了维护猪的健康和生产性能,大量的研究都在关注抗生素替代方案(alternatives)的开发。研究最广泛的替代方案包括益生素、益生菌、酸化剂、植物提取物和疾病预防性添加剂(neutraceuticals),如铜和锌。由于这些添加剂已经在上一个综述中作了充分的论述,因此本文将关注非常规的抗生素替代方案。本文将讨论抗菌肽、粘土矿物、卵黄抗体、精油、桉树油-中链脂肪酸、稀土元素和基因重组酶替代抗生素的潜力。通过文献的全面回顾发现,已经检验了许多化合物作为猪日粮中抗生素替代方案的可能性。遗憾的是,这些化合物中的绝大多数的试验结果并不一致,而且使用效果很少能达到抗生素的水平。因此,该领域似乎还需要进一步的研究,抗生素的完美替代方案还待发现。
