The effect of feeding diets including market crop wastes (sweet potato vines (Ipomoea batatas) and scarlet eggplant (Solanum aethiopicum)) on growth and digestibility was studied using 32 indigenous intact growing male goats. Adding elephant grass (Pennisetum purpureum), maize bran and Leucaena leucocephala leaves, four isocaloric and isonitrogenous diets (Sweet potato vines, Solanum, Mixed and Control) were formulated. After the growth trial, 12 goats were randomly selected for a digestibility trial with the same diets, and 8 goats for a feed preference test comparing the market wastes and elephant grass. Crude protein (CP) intake was highest (P < 0.05) for the Control (48 g/day) and lowest for the Sweet potato vines diet (23 g/day). Average daily gain was between 11.0 and 14.2 g/day, and similar between diets. The DM and CP digestibilities of the diets were 0.56 and 0.56 (Control), 0.62 and 0.56 (Mixed), 0.59 and 0.49 (Sweet potato vines), and 0.54 and 0.45 (Solanum), respectively. Faecal and urinary N excretions were highest in goats fed the Sweet potato vines and Solanum diets. Eggplant wastes were the least (P < 0.05) preferred. On average the goats spent 5% of their 8-hour time eating eggplant wastes, 34% on sweet potato vines and 36% on elephant grass. Growth performance and N retention were low due to the low intake of feed, especially eggplant wastes.  相似文献

提高经营环节兽药产品质量的思考   总被引:1,自引:0,他引:1  
当前经营环节的兽药产品合格率低于生产环节19个百分点。兽药经营企业规模小、数量多、质量管理水平差,基层管理部门监管能力不足。主要原因是假企业、假产品冲击市场,经营企业缺乏责任意识,对非法行为打击不力。通过完善配套法规、推行兽药GSP、监管重心后移、完善兽药监管信息系统等措施,兽药经营质量有望得到大的改善。  相似文献

This study aimed to examine village poultry consumption and marketing in Ethiopia in relation to gender, socio-cultural events and market access. The main objects of the research were producers, poultry markets, producer-sellers, and intermediary sellers in three locations representing different levels of market access in Tigray. About 3000 farm records were collected over a period of 12 months from 131 producers to obtain quantitative data on sales and consumption. Ninety-three semi-structured interviews with 58 producer-sellers and 35 intermediaries and 12 group discussions with these market actors were conducted to explore organization, price dynamics and socio-cultural aspects of poultry marketing. In total, 928 producer-sellers and 225 intermediaries were monitored monthly to examine participation by gender in poultry marketing. Better market access was associated with a shorter market chain and higher prices for the producers. Female-headed households had smaller poultry sales and consumption per household but sale and consumption per family member were 25% and 66% higher, respectively, than in male-headed households. While women dominated in the producer-sellers group, intermediaries were mainly men. Religious festivals periodically shifted local demand and prices of poultry. To improve the benefit of poultry keeping, poverty-stricken households may profit from better market access through better market information, infrastructure, market group formation and careful planning to match the dynamics in demand.  相似文献
