Thyme oil inclusion levels in a rabbit ration: Evaluation of productive performance, carcass criteria and meat quality under hot environmental conditions

The aim of this study was to determine the impact of thyme essential oil supplementation in rabbit rations on performance, carcass criteria, and meat quality under hot environmental conditions. A total of 75, 4-week-old Californian male rabbits were assigned to 5 dietary treatments until 12 weeks of *** rabbits were reared in an open house system(38C average ambient temperature and 26% to 35%relative humidity). Treatments were as follows: unsupplemented standard ration, negative control(CON); standard ration supplemented with 1.50 g/kg olive oil as carrier, positive control(POS);POS t 50 mg/kg thyme oil(TO1); POS t 100 mg/kg thyme oil(TO2); and POS t 150 mg/kg thyme oil(TO3). Dietary thyme oil up to 150 mg/kg improved(P < 0.001) feed intake and growth performance in comparison to CON. The highest average daily gain and most efficient feed conversion ratio(linear,P < 0.001 and quadratic, P < 0.001) were found for TO1 followed by TO2, TO3 and POS, *** incorporation of thyme oil improved(P < 0.001) carcass criteria and decreased(P < 0.001) perirenal and scapular fat without any side effects on internal organs. Notably, the water holding capacity of rabbit meat was greater(P < 0.001), and the lipid oxidation was lower(P < 0.01) in rabbits fed treated rations compared with CON. Differences were also recorded in oxymyoglobin and metmyoglobin contents in rabbit meat among treatments. In conclusion, thyme oil of a specified composition and to be added to a rabbit ration up to 100 mg/kg using 1.50 g/kg olive oil as a carrier can be used as an efficient feed additive for improving productive performance of rabbits under hot environmental conditions.

饲料博览 2015年第1期 14-14页

作者： Abdel-Wareth A A A lohakare J D

文章旨在研究蛋鸡饲粮中添加干薄荷叶(欧薄荷属)对蛋鸡产蛋性能、蛋品质和血液指标的影响。试验选择海兰褐蛋鸡(64周龄)150只,将其分成5组,分别添加干薄荷叶0、5、10、15、20 g·kg-1,试验期为12周。每个处理6个重复,每个重复5只鸡。在... 详细信息

文章旨在研究蛋鸡饲粮中添加干薄荷叶(欧薄荷属)对蛋鸡产蛋性能、蛋品质和血液指标的影响。试验选择海兰褐蛋鸡(64周龄)150只,将其分成5组,分别添加干薄荷叶0、5、10、15、20 g·kg-1,试验期为12周。每个处理6个重复,每个重复5只鸡。在试验过程中,64～68、68～72、72～76和64～76干薄荷叶组的蛋重、产蛋量、采食量显著增加(线性,P0.05)。血液中胆固醇含量显著下降(P<0.001),但随着薄荷叶的添加血清总蛋白增加(P=0.015)。研究结果表明,薄荷叶可以作为一种有效的饲料添加剂来提高蛋鸡产蛋后期的生产性能。
