Abstract

A 28-d experiment was conducted to investigate the effects of feed-conditioning temperature on the pellet quality, growth performance, intestinal development, and blood parameters of geese. A total of 180 one-day-old White Yuzhou goslings were randomly allotted to 5 treatment groups, with 6 replicates containing 6 birds each. Five diets were conditioned at 65, 70, 75, 80, and 85°C. Body weight and feed intake per pen basis were recorded from the arrival to the end of the trial. Blood and small intestine samples were collected on d 28 for analysis. The results showed that the pellet durability index (PDI), pellet hardness, and gelatinisation degree of starch (GDS) increased with increasing conditioning temperature (P < 0.05). The final body weight (FBW), average daily gain (ADG) and average daily feed intake (ADFI) of goslings significantly increased when conditioning temperature increased from 65 or 70°C to 80 or 85°C (P < 0.05), accompanied by unaffected feed conversion ratio (FCR) (P > 0.05). The villus height to crypt depth ratio (VH/CD) in the duodenum and ileum improved with increasing conditioning temperature (P < 0.05). Additionally, trypsin and amylase activity were enhanced when the conditioning temperature increased from 65 to 85°C (P < 0.05). No significant differences in the carcass traits and blood parameters of goslings were observed among the groups (P > 0.05). Overall, under the present experimental conditions, increasing the steam-conditioning temperature of pelleted feed improved pellet quality, growth performance, intestinal morphology, and digestive enzyme activity in goslings. Based on broken-line regression analysis, the lower critical conditioning temperature for ADG in geese from 1 to 28 d of age was 80.95°C.

摘要

进行了一项为期 28 天的实验,以研究饲料调质温度对鹅颗粒质量、生长性能、肠道发育和血液参数的影响。将 180 只 1 日龄白豫州鹅随机分为 5 个处理组,每组 6 个重复,每个重复 6 只鹅。将 5 种日粮在 65、70、75、80 和 85°C 下调质。从到达试验结束时,记录每栏的体重和采食量。在第 28 天收集血液和小肠样本进行分析。结果表明,颗粒耐久性指数(PDI)、颗粒硬度和淀粉糊化度(GDS)随调质温度的升高而升高(P < 0.05)。当调质温度从 65 或 70°C 升高到 80 或 85°C 时,鹅的最终体重(FBW)、平均日增重(ADG)和平均日采食量(ADFI)显著增加(P < 0.05),同时饲料转化率(FCR)不受影响(P > 0.05)。十二指肠和空肠的绒毛高度与隐窝深度比(VH/CD)随调质温度的升高而提高(P < 0.05)。此外,当调质温度从 65°C 升高到 85°C 时,胰蛋白酶和淀粉酶活性增强(P < 0.05)。各组鹅的胴体性状和血液参数无显著差异(P > 0.05)。总体而言,在本实验条件下,提高颗粒饲料的蒸汽调质温度可提高鹅的颗粒质量、生长性能、肠道形态和消化酶活性。基于折线回归分析,1 至 28 日龄鹅 ADG 的最低调质临界温度为 80.95°C。
