Effects Of Alfalfa On Laying Traits, Hatching Rate And Reproductive Hormones In Zi Goose

150 adult laying zi geese aged at 240d, 30 adult female geese were randomly divided into five groups, each with two repeat, the sex ratio of each repeat is 1:5, and the number of each repeat is 18. Experimental groups were added with the diet of 5%, 10%, 15%, 20% alfalfa meal, and 56 d for the trial period. The results show that: the feed intake and expected egg ratio of experimental groups were lower than that of the control. For the fourth test group(20% of the alfalfa), feed intake, feed/egg ratio were 19.1% and 20.0%lower than the control group (P <0.05). Test group and the control group feeding on egg-laying rate, feeding, egg production, egg weight each there was no significant difference (P> 0.05), but the test group egg weight illustrated improved trend compared with the control group; Test 1 Test 2 group fertilization rate, the hatching rate were 7.97%, 11.17% and 11.87%, 8.1% lower than that of the control, respectively, test three group and four group fertilization rate, the hatching rate were 14.41%, 10.90% and 11.30% , 2.66%higher than the control group. During the pilot, experimental group 1,3,4 profits increased by 13.96%, 13.68%, 22.01%, 20% respectively for the control group. In particular, Effect of group added with 20% alfalfa possessed the highest profit.251 Zi goose and 251 White goose eggs were divided into five groups respectively according to egg weight and divided into four groups according to egg shape index, and re-examine its egg, egg shape the relationship between the index and hatchability. The results show that: Zi goose and White Goose eggs weight were129.25±13.07 g, 128.11±12.04 g; eggs shape index were 1.457±0.068, 1.457±0.065, Zi goose and White Goose egg weight, egg shape index There was no significant difference(P> 0.05); Hatchability showed the first increase and then decrease with egg weight, egg shape index. Hatchability was the highest when Zi egg Hatchability was the highest when egg weight was 137.08 ~ 151.04 g and the egg shape index in the range 1.349 to 1.449.White Goose egg weight was among 131.16 ~ 144.88 g and the egg shape index 138.7 to 149.6.The addition of alfalfa in a proper ratio has no effect on the concentration of reproductive hormones in serum during the later laying stage. the experimental groups added 10%, 15% and 20% alfalfa showed rising tendency in P4, E2 compared with the control group(P> 0.05).
