为了研究甘草对氟苯尼考药动学的影响,试验以三黄鸡为试验动物,分为空白对照组、甘单酸组和甘草提取液组,分别灌服生理盐水、甘草酸和甘草提取液(按体重2 mL/kg),每天1次,连续灌服7d,然后各组灌服氟苯尼考并在规定时间点采样,利用高效液相色谱仪测定血药浓度后使用3P97软件进行分析.结果表明:甘草酸能显著降低氟苯尼考的吸收半衰期(t1/2Ka)、达峰时间(Tpeak);甘草提取液能显著降低氟苯尼考吸收半衰期、达峰时间、消除半衰期(t1/2K)、药时曲线下面积(AUC).说明连续灌服甘草酸7d可促进氟苯尼考在三黄鸡体内的吸收,而甘草提取液可显著加快氟苯尼考的吸收与排泄.

一场址的选择 1场地的选择 优质三黄肉鸡林下养殖应选择合适的场地,一般要求选择地势高燥、背风向阳、水资源丰富,远离居民区、道路、学校,交通方便、树冠较小的林园、果园等地方.切记要远离江河湖泊及养殖场密集的地方,鸡场与鸡场之间的生物安全距离不少于2000米,鸡场与居民点之间的距离应保持1000米以上;另外,要充分利用山区自然屏障的生物安全优势,最好一个山坡一个鸡场.

Water buffalo are a kind of widely bred herbivores in southern China region,it is an important part in cattle industry.However,due to the impact of traditional customs,the milk process of water buffalo was less than 20%,so the development and utilization prospect of water buffalo milk was enormous.Based on the current situation of Guangxi water buffalo milk production,the nutritional characteristics,resources advances and exploitation of the milk were presented,and the developmental directions and suggestions were put forward.

The climate features of southern area in China is characterized by high-temperature, high humidity and rainy, thereby bring many difficulties to the production of silage maize and leading to the higher corruption rate and poor quality. Since 2007, the effects of silage maize of the 12 cattle farms had been surveyed in Guangdong and Guangxi Provinces. The corruption rates vary form 10 % to 20 % and the losses of silage maize were more serious. Through analysis we found that the corruption of raw materials had much to do with freshness, water content, production process and the management. According to the causes of higher corruption rates in the South, the comprehensive measures including microbial fermentation technology was used to improve the quality of silage maize in the Southern Regions. The results showed that through using these methods, the corruption rate of silage maize was decreased obviously, while the crude protein content was increased to a certain degree and the quality of silage maize was greatly enhanced.

为了给三黄种鸡育成期的体能调控提供依据,通过试验测定其主要生产性能。试验将600只18～20周龄的三黄种鸡分为大、中、小3组,每组200只,记录其产蛋率、蛋重和种蛋合格率并进行统计处理。结果表明:中体重组在开产后产蛋率上升曲线比较平稳,种鸡平均产种蛋数多;小体重组和大体重组各项生产指标均表现不理想。
