| 摘 要： | 为探究日粮中添加藜麦(Chenopodium quinoa)对芦花鸡(Gallus domestiaus)生长性能、屠宰性能、器官指数与肠道形态的影响,选用49日龄的脱温健康芦花鸡150只,随机分成5组,每组3个重复,每重复10只鸡,设4个藜麦添加水平,即日粮中添加4%(Q4)、8%(Q8)、12%(Q12)的藜麦籽实(原粮)和12%藜麦糠(QS),以不添加藜麦原料为对照组(CK),进行为期75 d的饲养试验,测定其生长性能、屠宰性能、器官指数与肠道形态。结果表明:与对照组相比,1)Q4组终末体重提高了5.23%(P<0.05),Q8、Q12组腹泻率分别降低了47.7%、52.3%,QS组腹泻率增加了196%,各试验组死亡率均低于对照组;2)试验结束后Q8组活体重增加了4.65%(P<0.05),Q4、Q8和QS组屠宰率分别提高了3.29%、3.73%和3.54%(P<0.05),Q8、Q12组半净膛率分别提高了5.12%、3.82%(P<0.05),Q8组全净膛率提高了4.81%(P<0.05);3)QS组肾指数高于对照组(P<0.05),Q8、QS组胸腺指数分别是CK组的2.00倍和2.18倍(P<0.05);4)各试验组空肠和回肠绒毛高度、绒毛高度/隐窝深度(V/C)、QS组十二指肠绒毛高度均显著(P<0.05)高于对照组,Q4组十二指肠隐窝深度、QS组十二指肠、空肠和回肠隐窝深度显著(P<0.05)低于对照组;5)经济效益分析结果表明,Q4和QS组每只鸡的毛利润比对照组分别高1.75元和1.58元。日粮中添加藜麦籽实与藜麦糠可明显提高芦花鸡生长性能和屠宰性能,对改善其器官指数和肠道形态有一定作用,添加4%藜麦籽实经济效益更好。 |

| Abstract: | To investigate effects of quinoa supplementation on growth performance, slaughter performance, organ index and intestinal morphology of Luhua chickens, a total of 150 healthy 49-day-old Luhua chickens were randomly divided into five groups with three replicates per group and ten chickens per replicate. Four quinoa supplemental levels were set, 4% (Q4), 8% (Q8), 12% (Q12) quinoa seed (raw grain) and 12% quinoa bran (QS) were added into the current diet, and no quinoa raw material was used as control group (CK). The feeding experiment lasted for 75 days.Growth performance, slaughter performance, organ index and intestinal morphology were determined. The results showed as follows: compared with CK, 1) final body weight of group Q4 was significantly increased by 5.23% (P<0.05), diarrhea rate in Q8 and Q12 groups decreased by 47.7% and 52.3%, respectively, while that in QS group increased by 196%, mortality rate in all experimental groups was lower than that in CK. 2) After the end of the experiment, live body weight of Q8 group increased by 4.65% (P<0.05), slaughter percentage in Q4, Q8 and QS groups were increased by 3.29%, 3.73% and 3.54% (P<0.05), respectively; half eviscerated percentage in Q8 and Q12 groups was increased by 5.12% and 3.82 (P<0.05), respectively, and eviscerated percentage in Q8 group was increased by 4.81% (P<0.05). 3) Renal index in QS group was significantly higher than that in CK (P<0.05), and thymus index in Q8 and QS groups was 2.00 times and 2.18 times of CK, respectively (P<0.05). 4) Villus height of jejunum and ileum, ratio of villus height to crypt depth (V/C) and duodenum villus height of QS group were significantly higher than those of CK (P<0.05), Crypt depth of duodenum, jejunum and ileum in Q4 group and QS group were significantly (P<0.05) lower than those in CK. 5) Economic benefit analysis results showed that the gross profit per chicken of Q4 and QS groups was 1.75 yuan and 1.58 yuan higher than that of CK, respectively. Addition of quinoa seed and quinoa bran in diet could significantly improve growth performance and slaughter performance of Luhua chickens, and also had certain effects on improving organ index and intestinal morphology, and 4% quinoa seed had better economic benefit. |
