沙葱乙醇提取物对肉仔鸡生产性能的影响

试验选择120只1日龄罗斯308商品肉鸡随机分为4个处理组,每个处理3个重复,每个重复10只鸡。对照组饲喂基础日粮,试验组分为AWEⅠ组、AWEⅡ组和AWEⅢ组,分别在基础日粮中添加100、300和500 mg/kg沙葱乙醇提取物(AWE),研究其对肉仔鸡生产性能的影响。结果表明,沙葱乙醇提取物对肉仔鸡生产性能无显著影响(P0.05),但有促进日增重、提高采食量及降低料肉比等指标的趋势。

围栏禁牧与放牧对草地生态系统固碳能力的影响

草地生态系统固碳能力对全球碳贮量的大小有重要影响。放牧作为草地最广泛的利用方式之一影响着草地的碳贮量,过度和不合理的放牧方式造成草地退化,引起草地碳的损失。围栏禁牧与放牧对草地生态系统固碳能力的影响主要包括对植被生产力和土壤碳贮量的影响,本文对有关的报道进行了综述。结果显示,由于受植被凋落物、群落结构和气候等多因素的影响,围栏禁牧对草地植被生产力有正面或负面的效应;放牧对植被生产力的影响也没有一致的结果,此外,放牧对植被生产力的影响还与放牧的强度有关。围栏禁牧与放牧可以通过多种途径对草地土壤碳贮量产生正面或负面的影响。总之,围栏禁牧与放牧对草地生态系统固碳能力的影响是复杂多样的,需要对草地碳贮量进行估算,并对相关的机制进行研究,这样才能在草地管理方面做出合理的决策。     

Effect of multi-enzymes in combination with a direct-fed microbial on performance and welfare parameters in broilers under commercial production settings

The objective of this study was to determine the response of broilers to the combination of multi-enzymes and direct-fed microbial (DFM) under commercial production settings. A total of 7,000 1-day-old male broilers (Ross 308) were distributed over 10 pens (700 broilers/pen). Two dietary treatments were tested using complete randomized design, including a control diet and a test diet with addition of multi-enzymes (xylanase, amylase, and protease (XAP)] and DFM (a combination of spores from 3 strains ofBacillus amyloliquefaciens). Pelleted diets were offered ad libitum in 3 phases and water was freely available. During starter and grower phases (0 to 21 d), the enzyme and DFM combination resulted in improved FE (P < 0.05). During the finisher phase, higher feed intake and BW gain (P < 0.05) were observed for the test group. Overall, there were significantly higher feed intake, BW gain, and lower water-to-feed ratio in test group compared to the control group. This was related to improved (P < 0.05) modified production efficiency factor which was calculated based on final BW, survival rate, feeding period, and mortality-weight-corrected FCR. The test group had improved litter quality and a reduced foot-pad lesion score compared to the control. In addition, there was a tendency (P < 0.1) of reducingClostridium perfringens population in cecal digesta and higher lactic acid content in the ileal digesta, when expressed on an as-is basis, in the test group. In this study, we demonstrated that using a multi-enzymes and DFM combination in the diet for broilers can result in improved FE in starter/grower phases and animal welfare parameters, and lead to improved production efficiency under commercial settings.
