摘要

摘要本研究旨在评价肉桂和枯草芽孢杆菌对肉鸡生长、肉质特性和脂质代谢的影响。在实验1和2中,总共320日龄肉鸡被分配到D1(对照)、D2(4g肉桂/kg)、D3(6g肉桂/kg)和D4(8g肉桂/kg。在实验1中,不同日粮在生长和肉产量方面没有观察到显著差异。然而,试验日粮在肉的持水能力(WHCM)、肉的烹饪损失(CLM)、血脂谱(BLP)、感官质量评分(SQS)(p>0.05)和风味(p<0.05)方面均优于对照日粮,除SQS外(p<0.001)。尽管如此,D5倾向于增加生长、肉产量、WHCM和SQS,并降低CLM和BLP。在两个实验中,大腿肉的SQS均高于胸脯肉。因此,6克肉桂/公斤日粮可用于生产安全、优质和具有成本效益的肉鸡。

Use of cinnamon and Bacillus subtilis probiotics in the diet of broiler chickens
Abstract The present study was carried out to evaluate the effect of cinnamon and Bacillus subtilis on the growth, meat characteristics, and lipid profiles of broiler chickens. In experiments 1 and 2, a total of 320 day-old broiler chicks were assigned to D1 (control), D2 (4 g cinnamon/kg), D3 (6 g cinnamon/kg), D4 (8 g cinnamon/kg) with four replicates, and D1 (control), D2 (0.4 g B. subtilis (BS)/kg), D3 (0.6 g BS/kg), D4 (0.8 g BS/kg), D5 (6 g cinnamon/kg) with three replicates, and 10 chicks/replication for 35 and 30 days, respectively. In experiment 1, no significant difference was observed among diets for growth and meat yield. However, test diets performed better than the control diet in terms of water-holding capacity of meat (WHCM), cooking loss of meat (CLM), blood lipids profiles (BLP), sensory quality score (SQS) (p > 0.05), and flavor (p < 0.05). In experiment 2, there was no significant difference among diets for growth, meat yield, WHCM, CLM, and BLP of the bird (p > 0.05), except for SQS (p < 0.001). Notwithstanding, the D5 tended to increase growth, meat yield, WHCM, and SQS, and decrease CLM and BLP. Thigh meat showed higher SQS than breast meat in both experiments. Therefore, the 6 g cinnamon/kg diet may be used for producing a safe, quality, and cost-effective broiler.

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
