蛋白质是维持家兔生命活动,保证其健康生长、正常生产的物质基础。家兔所需蛋白质来源于饲粮,兔能有效地消化蛋白质,尤其是青饲料中的蛋白质。蛋白质在兔体内的消化和营养生理与其他单胃、反刍家畜不同,小肠中未被消化吸收的蛋白质和氨基酸可以被盲肠中的微生物利用,形成菌体蛋白,随软粪排出,被家兔重新食入、消化吸收再利用。家兔食软粪的特性可以改善低质量的蛋白质。Jecsai(1985)报道,成年免食入含蛋白质12.8%的饲粮时,食粪特性有助于改善兔的必需氨基酸的供应,并且氮沉积、血清尿素氮、血清氨基酸指标都有提高。1 蛋白质 家兔从日粮中摄取的蛋白质,主要用于体组织更新、生长、妊娠、泌乳及产毛。在日粮配合上通常以粗蛋白和必需氨基酸含量作为计算配方的指标。 相似文献

日粮中纤维性物质是植物细胞壁的主要组成部分,在过去一般不认为它具有营养价值,因此,对于日粮纤维的认识和利用较晚,并且在初期仅限于对反刍动物的研究。时至今日,随着日粮纤维被列入第七大营养元素,人们对日粮纤维在单胃动物中利用的兴趣日益增加,尤其家兔方面也越来越多。 相似文献

As part of an experiment aiming to modify the meat fatty acid profile, this work studied the growth and carcass traits as affected by various dietary ratios of sunflower oil and linseed oil. A diet without added oil served as a control (C). Four other diets were equally 4% oil-enriched but they differed in the incorporation ratios of sunflower oil (S) to linseed oil (L), i.e. 4% S to 0% L (diet 4%S), 3% S to 1% L (diet 3:1%SL), 2% S to 2% L (diet 2:2%SL) and 0% S to 4% L (diet 4%L). The oil-rich diets had slightly higher digestible energy contents (11.4 vs 10.6 MJ/kg) than the C feed. In each group 10 litters of 7 to 9 Pannon White kits per litter were studied in the pre-weaning period from 21 to 35 days old. Growth and slaughter traits were assessed with 50 and 30 rabbits per group, respectively. No significant effects of diets were found on litter and doe performances. The only significant differences in growth performance of the C, 4%S, 3:1%SL, 2:2%SL and 4%L rabbits were for the 35–49 day feed intake (88, 86, 84, 84 and 83 g per day, respectively, P = 0.046), the 35–84 day growth rate (36, 38, 37, 35 and 37 g/day, P = 0.034) and the 84-day body weight (2608, 2703, 2664, 2565 and 2628 g, respectively, P = 0.022). There were several significant differences in carcass traits including the weight of reference carcass (1357, 1391, 1388, 1380 and 1369 g, respectively, P = 0.004) and left longisimus dorsi meat (78, 79, 81, 81 and 76 g, respectively, P = 0.046) of rabbits. The diets had major effects on the L*, a* and b* colour values (lightness, redness and yellowness) of meat and fat. Carcass colour of the C and 4%S rabbits was closer and the 4%L rabbits was further from the European consumer's preference of light coloured, less red and slightly yellow rabbit meat. Our result reveals the importance of age and body weight at slaughter. Taking the growth and slaughter performances and, the recent belief of human health benefits from lower n− 6/n− 3 FAs dietary ratios into account, the 2:2%SL diet seems most appropriate if the interests of the raisers, meat processors and buyers are considered equally. 相似文献
