| 1 | Alternatives to antibiotics as growth promoters for use in swine production:a review显示文摘In the past two decades, an intensive amount of research has been focused on the development of alternatives to antibiotics to maintain swine health and performance. The most widely researched alternatives include probiotics,prebiotics, acidifiers, plant extracts and neutraceuticals such as copper and zinc Since these additives have been more than adequately covered in previous reviews, the focus of this review will be on less traditional alternatives.The potential of antimicrobial peptides, clay minerals, egg yolk antibodies, essential oils, eucalyptus oil-medium chain fatty acids, rare earth elements and recombinant enzymes are discussed. Based on a thorough review of the literature, it is evident that a long and growing list of compounds exist which have been tested for their ability to replace antibiotics as feed additives in diets fed to swine. Unfortunately, the vast majority of these compounds produce inconsistent results and rarely equal antibiotics in their effectiveness. Therefore, it would appear that research is still needed in this area and that the perfect alternative to antibiotics does not yet exist. | Philip A Thacker | 2014 | Journal of Animal Science and Biotechnology2014，5，2： | 23 |
| 2 | 养猪生产中应用的抗生素生长促进剂替代方案(综述)显示文摘在过去的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。 | 孙相俞 万建美 潘雪男 Philip A.

| 4 | Use of a post-production fractionation process improves the nutritional value of wheat distillers grains with solubles for young broiler chicks显示文摘Background: Post-production fractionation of wheat distillers grains with solubles(DDGS) increases their crude protein content and reduces their fiber content.This 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 design.The control diet was based on wheat and soybean meal and contained 20% regular wheat DDGS.The experimental diets contained 5,10,15 or 20% fractionated wheat DDGS added at the expense of regular wheat DDGS.Results: The ATTD of dry matter and gross energy were linearly increased(P < 0.01) as the level of fractionated wheat DDGS in the diet increased.Nitrogen 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 increased.Feed 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 energy.These changes in chemical composition supported increased weight gain of broilers fed wheat DDGS. | Philip Thacker Aman Deep Eduardo Beltranena | 2013 | Journal of Animal Science and Biotechnology2013，4，3： | 1 |
