Moringa stem meal (MSM) with a high level of crude fibre (CF) might be developed and utilized in herbivorous geese as an unconventional feedstuff. The aim of this study was to investigate the effect of the MSM level in the diet on the growth performance, slaughter performance, breast meat quality and serum biochemical parameters in geese from 22 to 70 days of age. A one-factor completely randomized design was adopted in our study. A total of one thousand eight 21-day-old geese were randomly divided into six groups, with six replicates per group and 28 birds per replicate. The geese were fed diets containing MSM levels of 0, 20, 40, 60, 80 or 100 g/kg during day 22-70. The dietary MSM level had no effect (p > .05) on the final body weight (BW), average daily gain (ADG) or average daily feed intake (ADFI). The feed/gain ratio (F/G) increased linearly (p < .001) as the dietary MSM level increased. No differences (p > .05) were observed in the slaughter performance, meat quality and the relative organ weight (except for thymus) of the geese (p > .05). The relative weight of the thymus in the geese fed diets with supplementation of MSM was higher than that in the non-supplemented MSM control group (p < .05). In addition, 100 g MSM/kg of diet decreased the serum glucose (GLU) level (p < .05) and increased the alanine transaminase (ALT) enzyme activity (p = .03). Dietary MSM levels of no more than 60 g/kg had no effects on the growth performance and slaughter performance, whereas diets with 100 g MSM/kg increased the F/G and serum ALT enzyme activity, as well as decreasing the serum GLU level. Therefore, MSM provided at a reasonable level could be developed as an unconventional feedstuff for geese at the finisher period.
高粗饲料纤维(CF)的辣木叶粉(MSM)可能被开发并用作草食性鹅的非常规饲料。本研究旨在探讨饲粮中 MSM 水平对 22-70 日龄鹅生长性能、屠宰性能、胸肌品质和血清生化参数的影响。本研究采用单因素完全随机设计。共选用 1800 只 21 日龄鹅,随机分为 6 组,每组 6 个重复,每个重复 28 只鹅。22-70 日龄时,鹅饲粮中 MSM 水平分别为 0、20、40、60、80 和 100 g/kg。饲粮 MSM 水平对末重(BW)、平均日增重(ADG)或平均日采食量(ADFI)均无影响(p>0.05)。随着饲粮 MSM 水平的增加,料重比(F/G)呈线性增加(p<0.001)。鹅的屠宰性能、肉质和器官相对重量(胸腺除外)无差异(p>0.05)。饲粮添加 MSM 可提高鹅的胸腺相对重量(p<0.05)。此外,饲粮添加 100 g MSM/kg 降低了血清葡萄糖(GLU)水平(p<0.05),增加了丙氨酸转氨酶(ALT)酶活性(p=0.03)。饲粮 MSM 水平不超过 60 g/kg 对生长性能和屠宰性能无影响,而 100 g MSM/kg 饲粮增加了 F/G 和血清 ALT 酶活性,降低了血清 GLU 水平。因此,合理水平的 MSM 可作为育肥期鹅的非常规饲料。
