不同组成合生元对蛋鸡生产性能的影响
发布时间:2019-03-07 17:54
【摘要】:随着人们对饲料安全问题的深入了解,对饲料添加剂的选择已经成为了一个热门话题。乳酸菌能够调节动物肠道的菌群平衡,从而提高动物的食物消化率,并且能够很好地降低动物产品的胆固醇;另外,红曲霉中药合生元添加剂也是一种绿色安全的饲料添加剂。本试验采用216只400日龄、体重均匀、产蛋率相近、体况健康的海蓝褐蛋鸡,随机分成3组,每组设置3个重复,每个重复24只鸡,分别标记为对照组(采食基础日粮)、试验1组(基础日粮添加乳酸菌-红曲霉中药合生元混合添加剂)和试验2组(基础日粮中添加红曲霉中药合生元制剂)。试验共分为两个阶段,即预试期7天、试验期49天。试验期间保证充足的光照、干净的饮水和清洁的鸡舍。正式试验开始后每天捡蛋1次,并且记录每个重复组试验鸡的产蛋数、产蛋重及蛋鸡死亡数,试验结束前3天采用全收粪法进行鸡的养分消化率的测定,记录每天的给料量、剩料量。48小时后用纸盒收集试验鸡的粪便,用于测定养分含量,并计算蛋鸡消化吸收日粮中干物质、粗蛋白、有机物及钙、磷的表观消化率。试验结果如下:1、在生产性能方面:乳酸菌-红曲霉中药合生元混合添加剂组对蛋鸡的生产性能有很好的改善作用,能显著提高蛋鸡产蛋率,同时显著降低蛋鸡料蛋比。2、在蛋品质方面:乳酸菌-红曲霉中药合生元混合添加剂组对平均蛋重也有所提高。红曲霉中药合生元组能够显著改善鸡蛋的各项常规指标。乳酸菌-红曲霉中药合生元混合添加剂组在哈夫单位、蛋壳厚度方面有显著地提高,在提高蛋壳红色度、黄色度方面也有显著的改善。两个试验组对提高蛋壳亮度方面均有了显著地改善。3、在蛋营养成分方面:乳酸菌-红曲霉中药合生元混合添加剂组和红曲霉中药合生元添加剂组对蛋黄中各种营养成分的含量均有较好的影响,而且乳酸菌-红曲霉中药合生元混合添加剂组的效果相较于红曲霉中药合生元组好。4、在蛋鸡养分表观消化率方面:乳酸菌-红曲霉中药合生元混合添加剂组对蛋鸡日粮中各营养成分的表观消化率均有显著地提高。5、在贮存性方面:乳酸菌-红曲霉中药合生元混合添加剂组和红曲霉中药合生元组在提高鸡蛋贮存时间方面均有积极地作用,但蛋黄系数方面未见显著性差异。6、在抗氧化性方面:乳酸菌-红曲霉中药合生元混合添加剂组和红曲霉中药合生元组对提高鸡蛋蛋黄的抗氧化性方面均有着积极的作用。以上试验结果表明,两个组合对蛋鸡的生产性能均有所提高,红曲霉中药合生元组合更能提高鸡蛋的常规品质,而乳酸菌-红曲霉中药合生元混合添加组合对鸡蛋的贮存时间和抗氧化活性方面更有所帮助。
[Abstract]:With the deep understanding of feed safety, the choice of feed additives has become a hot topic. Lactic acid bacteria can regulate the balance of flora in animal intestines so as to improve the food digestibility of animals and reduce the cholesterol of animal products. In addition Monascus Chinese medicine additive is also a green and safe feed additive. 216 sea-blue brown layers of 400-day-old, uniform weight, similar laying rate and healthy body condition were randomly divided into three groups, each group was divided into 3 groups, each of which was labeled as the control group (the basal diet was taken), and the control group was divided into three groups: the control group and the control group. Experimental group 1 (basic diet supplemented with lactic acid bacteria-Monascus Chinese medicine mixed additive) and test group 2 (basic diet supplemented with Monascus Chinese medicine compound preparation). The experiment was divided into two stages: 7 days pre-test period and 49 days trial period. Ensure adequate light, clean drinking water and a clean chicken coop during the trial. The eggs were collected once a day after the beginning of the formal experiment, and the number of laying eggs, laying weight and death of each repeated group were recorded. Three days before the end of the experiment, the nutrient digestibility of the chickens was measured by the method of total feces, and the daily feed quantity was recorded. 48 hours later, the feces of the tested chickens were collected with paper tray for the determination of nutrient content, and the apparent digestibility of dry matter, crude protein, organic matter, calcium and phosphorus were calculated for digestion and absorption by laying hens. The results were as follows: 1. In the aspect of production performance: the mixed additive group of lactic acid bacteria and Monascus herbal medicine could improve the performance of laying hens, significantly increase the laying rate of laying hens, and at the same time significantly reduce the feed to egg ratio of laying hens. In the aspect of egg quality: the mixed additive group of lactic acid bacteria and Monascus herb also improved the average egg weight. Aspergillus monascus Chinese medicine combined group can significantly improve the routine index of eggs. In the mixed additive group of lactic acid bacteria and Monascus herb, the thickness of egg shell was significantly increased in Hafu unit, red degree and yellow color of egg shell were also improved significantly. Both groups had a significant improvement in improving eggshell brightness. 3, In the aspect of nutrient composition of egg: the mixed additive group of lactic acid bacteria-Monascus Chinese medicine and Monascus Chinese medicine compound additive group had a good effect on the content of all kinds of nutritional components in egg yolk. Moreover, the effect of the mixed additive group of lactic acid bacteria and Monascus Herbal medicine was better than that of the mixed additive group of Monascus Herbal Medicine. 4, In the aspect of apparent digestibility of nutrients in laying hens, the apparent digestibility of nutrients in laying hens was significantly increased in the mixed additive group of lactic acid bacteria and Monascus herbal medicine. 5, In the aspect of storage property: the mixed additive group of lactic acid bacteria-Monascus Chinese medicine and Monascus Chinese medicine compound additive group had positive effect on improving the storage time of eggs, but there was no significant difference in egg yolk coefficient. 6, In the aspect of anti-oxidation: the mixed additive group of Lactobacillus-Monascus Chinese medicine and Monascus Chinese medicine combination group have positive effect on improving the antioxidation of egg yolk. The results showed that the two combinations could improve the production performance of laying hens, and the combination of Monascus and traditional Chinese medicine could improve the routine quality of eggs, and the quality of eggs could be improved by the combination of Monascus and traditional Chinese medicine. The mixed addition of lactic acid bacteria and Monascus herb was more helpful to the storage time and antioxidant activity of eggs.
