Effects of compound Chinese herbal medicine and probiotics on egg production,egg quality and economic benefit of laying hens
This experiment aims to explore the effects of compound Chinese herbal medicine and probiotic preparations on egg production,egg quality,and economic benefits of laying hens. Select 2100 Hailan brown laying hens at the late stage of egg laying,aged around 50 weeks,and randomly divide them into 7 groups,with 1 group for every 10 replicates and 1 replicate for every 30 chickens. Add 0,0.02,0.04,0.08,0.16,0.32,and 0.64％ of compound preparations(with a 5:1 ratio of compound Chinese herbal medicine and probiotic preparations)to the basic diet as experimental groups Ⅰ to Ⅶ,for a total of 42 days. The results showed that compared with experimental group Ⅰ,the egg laying rates of experimental groups Ⅲ,Ⅴ,and Ⅵ were significantly increased by 8.78％,8.82％,and 7.67％,respectively(P<0.05). Compared with experimental group Ⅰ,the soft breaking rate of experimental groups Ⅲ,Ⅴ,and Ⅶ was significantly reduced by 34.09％,36.36％,and 32.58％,respectively(P<0.05). Compared with experimental group Ⅰ,the feed to egg ratio of experimental groups Ⅲ,Ⅵ,and Ⅶ was significantly reduced by 4.53％,4.12％,and 3.70％,respectively(P<0.05). The eggshell strength of Experiment Ⅲ and Ⅴ groups was significantly improved compared to Experiment Ⅰ group(P<0.05);The protein height of experimental groups Ⅲ and Ⅴ was significantly increased compared to the control group(P<0.05);The Hasselblad units of experimental groups Ⅲ,Ⅴ,and Ⅵ were significantly increased compared to the control group(P<0.05);The feed cost of experimental groups Ⅴ,Ⅵ,and Ⅶ significantly increased compared to the control group(P<0.05);The total farming expenditure of experimental groups Ⅵ and Ⅶ was significantly increased compared to the control group(P<0.05);The egg sales income of experimental groups Ⅲ,Ⅴ,and Ⅵ significantly increased compared to the control group(P<0.05);The net profit of Experiment Ⅲ and Ⅴ groups significantly increased by 0.39 and 0.33 yuan respectively compared to the control group(P<0.05). In summary,under the conditions of this experiment,the egg quality and economic benefits of Group Ⅲ were the best.
