摘要

Twenty crossbred 3–4-month-old male lambs of uniform body weight were used to assess the effect of raw and processed cottonseed (Gossypium) meals (CSM) on nutrient utilisation and rumen fermentation patterns. Lambs were assigned to five dietary treatments in a completely randomised design and fed isonitrogenous and isocaloric concentrate mixtures containing 30% deoiled groundnut cake (DGNC) (control), 40% of either raw, 45 min cooked, 1% calcium hydroxide (Ca(OH)₂) or iron (1 part free gossypol (FG):0.3 parts iron) treated CSM. The concentrate mixtures were fed to meet 80% of crude protein requirements (NRC, 1985) with ad libitum access to chopped maize hay (Zea mays). A metabolic trial of 6 days duration was conducted after 135 days of feeding, and rumen liquor was collected for 2 days at its end. Incorporation of 40% raw CSM resulted in reductions (PPPPPP mg FG intake per day) adversely affected utilisation of nutrients and rumen fermentation. This depression was alleviated to the greatest extent by 45 min cooking and 1% calcium hydroxide treatment. Iron treatment of CSM had little overall benefit.

用杂种的3 - 4月龄的均匀体重的雄性羔羊来评估原料和加工的棉籽（CSM）对养分利用和瘤胃发酵模式的影响。羔羊被分配到五个饮食治疗完全随机设计，并喂养含有30％脱油花生饼（DGNC）（对照）的等氮和等热量浓缩物混合物，40％熟的，45分钟煮熟的，1％氢氧化钙（Ca（OH）2）或铁（1份游离棉酚（FG）：0.3份铁）处理的CSM。饲喂浓缩物混合物以满足80％的粗蛋白要求（NRC，1985），随意取用切碎的玉米干草（玉米）。饲养135天后进行6天的代谢试验，并在其最后收集瘤胃液2天。加入40％原料CSM导致减少（每天PPPPPP mg FG摄入量）对养分和瘤胃发酵的利用产生不利影响。45分钟烹饪和1％氢氧化钙处理最大程度地减轻了这种抑郁症。 CSM铁的治疗几乎没有什么好处。
