摘要

本试验旨在研究早期断奶并补饲代乳粉对羔羊生长性能、消化性能、血清生化指标及肉品质的持续影响。选取60只体重[（8.26±2.14） kg]、日龄[（20±1）日龄]相近的健康湖羊公羔，随机分成随母哺乳组（ER组）和早期断奶组（EW组），每组6个重复，每个重复5只羔羊。ER组羔羊饲喂母乳+开食料，至60日龄断母乳；EW组羔羊饲喂代乳粉+开食料，至开食料采食量达到300 g/d时停止饲喂代乳粉。所有羔羊从20日龄开始补饲开食料至65日龄，之后过渡至育肥颗粒料。羔羊65日龄前每隔10 d称重，65日龄后每隔30 d称重；在羔羊65、120、180日龄晨饲前颈静脉采血测定血清生化指标；在55~65日龄、115~125日龄、170~180日龄阶段，每个重复选取1只（共12只）羊进行消化代谢试验；在180日龄，每个重复选取1只（共12只）羊屠宰测定肉品质。结果显示：1）EW组羔羊46~55日龄阶段平均日增重显著低于ER组（P<0.05），91~120日龄阶段平均日增重显著高于ER组（P<0.05）。2）EW组羔羊55~60日龄、115~125日龄、170~180日龄阶段各营养物质消化率相较ER组均未出现显著差异（P>0.05）。3）EW组羔羊65、120日龄时血清尿素氮、生长激素含量显著高于ER组（P<0.05），EW组羔羊180日龄时血清β-羟丁酸含量显著低于ER组（P<0.05）。4）早期断奶并补饲代乳粉对羔羊180日龄宰前活重、屠宰率及肉品质指标均无显著影响（P>0.05）。综上所述，早期断奶并补饲代乳粉降低了羔羊哺乳阶段（25~65日龄）的生长性能，但提高了育肥前期（66~120日龄）羔羊的生长性能，对育肥后期（121~180日龄）羔羊的生长性能、消化性能及肉品质均没有显著影响。

Abstract

The objective of present study was to assess the persistent effects of early weaning and supplementary feeding milk replacer on growth performance, digestive performance, serum biochemical indices and meat quality of lambs. Sixty healthy Hu sheep male lambs with similar days of age[(20±1) days of age] and body weight[(8.26±2.14) kg] were selected and assigned into two groups, including reared with mother milk group (ER group, as control) and early weaning group (EW group). Each group had 6 replicates with 5 lambs in each replicate. Lambs in ER group were reared with mother milk+starter until 60 days of age. Lambs in EW group were fed milk replacer+starter until the starter intake reached 300 g/d. All lambs were fed starters from 20 to 65 days of age, then transferred to finishing granulated feed. Lambs were weighed every 10 days before 65 days of age and every 30 days after 65 days of age. Blood samples were collected before morning meal at 65, 120 and 180 days of age. The digestion and metabolism experiment was carried out with 12 lambs (one lamb in each replicate) during 55 to 65 days of age, 115 to 125 days of age and 170 to 180 days of age. Slaughter of 12 lambs (one lamb in each replicate) at 180 days of age to measure meat quality. The results showed as follows:1) the average daily gain of lambs in EW group at the stage of 45 to 55 days of age was significantly lower than that in ER group (P<0.05), which was opposite at the stage of 91 to 120 days of age. 2) There was no significant difference in nutrient digestibility between two groups at the stages of 55 to 60 days of age, 115 to 125 days of age and 170 to 180 days of age. 3) The contents of serum urea nitrogen and growth hormone of lambs at 65 and 120 days of age in EW group were significantly higher than those in ER group (P<0.05), but serum β-hydroxybutyric acid content of lambs at 180 days of age in EW group was significantly lower than that in ER group (P<0.05). 4) Early weaning and supplementary feeding milk replacer did not affect the live weight before slaughter, dressing percentage and meat quality of lambs at 180 days of age (P>0.05). In summary, early weaning and supplementary feeding milk replacer decreases the growth performance of lambs during lactation stage (25 to 65 days of age), but increases the growth performance of lambs during early finishing stage (66 to 120 days of age). Whereas early weaning and supplementary feeding milk replacer has no impacts on growth performance, digestive performance and meat quality of lambs during late finishing stage (121 to 180 days of age).
