Effects of Heutral Detergent Fiber Level of Starter on Growth Performance and Digestive Tract Development of Suckling Lambs
摘要
Abstract
In order to investigate the effects of neutral detergent fiber( NDF)level of starter on growth per-formance and digestive tract development of suckling lambs,twenty-four healthy new born male Hu lambs with similar birth weight[(3.01±0.12)kg]were divided into 4 groups with 6 lambs in each group by a one factor design. Lambs in control group were ewe reared without dietary supplementation,and those in high,medium and low NDF groups were ad libitum fed starter with 17.01%,13.65% and 11.32% NDF,respectively,based on ewe reared from 7 days of age. All lambs were slaughtered at 35 days of age to determine weight and the volume of each part of digestive tract and the length of each part of intestinal tract. The results showed as fol-lows:1)final weight,average daily gain and carcass weight of high NDF group were significantly higher than those of control group( P<0.05),and carcass weight of high NDF group was significantly higher than that of low NDF group(P<0.05). 2)Abomasum weight of high,medium and low NDF groups was significantly higher than that of control group( P<0.05),and reticulorumen volume of high NDF group was significantly higher than that of control group(P<0.05);abomasum weight of high NDF group was significantly higher than that of control group and low NDF group( P<0.05). 3)Jejunum weight of high and low NDF groups was significantly higher than that of control group( P<0.05),and jejunum volume of high NDF group was signifi-cantly higher than that of control group(P<0.05). It is concluded that the optimal NDF level of starter for suckling lambs is 17.01% under the conditions in the present study,and lambs can obtain best growth perform-ance and digestive tract development under the above level.关键词
