Different vitamin effect in chicken diets


Test with chicken shell eggs for the parents on behalf of Roman Brown breeder. Test Location: Institute of Animal breeder farm in Sichuan Province. Et Chinese food to add multi-dimensional and the four ten thousandths ten thousandths,[link widoczny dla zalogowanych], Hua Luo Duowei, imported multi-dimensional, all are four ten thousandths. Test in adjacent carried out three kinds of sheds. One sheds a total of six, including 1,3,5-dimensional as the Chinese group, diet supplemented ten thousandths; 2,4,6 as Hua Luo Duowei group, diets supplemented with three ten thousandths. II a total of ten sheds, where 1,3,[link widoczny dla zalogowanych],5,7,9 as the Chinese multi-dimensional group, diets supplemented with four ten thousandths, 2,4,6,8,10 imported multi-dimensional group, diet Add four ten thousandths. Three sheds were two, commodity chicken diets as a cost-effective multi-dimensional analysis of five ten thousandths of the control group. Groups, which are listed daily egg production records,[link widoczny dla zalogowanych], broken egg rate, feed consumption, chicken deaths. Trial began Aug. 8, 1996. After two weeks of pre-tests, to formally test the twenty-fourth week. Test records the end of the end of thirty weeks of age, testing of a total of ten weeks, each experimental group were hatching eggs at thirty weeks, the eggs from hatching in the incubator and placed inside the machine evenly, packet records fertilization rate, hatching rate, healthy child rate. Test basal diet containing 2750 kcal metabolic energy / kg, crude protein 17.5%, methionine 0.35%, 0.81% lysine, 3.5% calcium, phosphorus 0.46%. 2 Results 2.1 different vitamins and chicken egg traits results in Table 1: Chinese imports of multidimensional multi-dimensional group than in the egg production rate of 2.51% group: 35 weeks egg weight, the Chinese group was the highest multi-dimensional, import multi-dimensional group was the lowest, a difference of 1.49 g groups; import multi-dimensional set of broken egg was the lowest, Hua Luo Duowei group was the highest, a difference of 0.25%. Table 1 living index and rate of egg-laying chicken, egg weight, broken egg rate of 2.2 between the different vitamins and chicken hatching traits results in Table 2 Description: Import multi-dimensional group of the three groups the highest hatching rate, compared Hua Luo Duowei group higher than 0.88%. Healthy child rate, fertilization rate was the highest Luoduo Wei Hua, of which the Chinese multi-dimensional group (ten thousandths) of the fertilization rate and rate of healthy young multi-dimensional than the Chinese group (four ten thousandths) were 1.12% and 0.45% higher. S, Table 2 composite index and the eggs fertilized living rate, hatching rate, healthy relationship between the rate of 2.3 child benefit analysis in 10-week trial period, multi-dimensional group of Chinese net income per hen more revenue than imports multidimensional 1.85 yuan. Addition of one ten thousandths of Chinese multi-dimensional than four ten thousandths income of 0.71 yuan more per hen. In this experiment,[link widoczny dla zalogowanych], young chicks home prices to 2.8 yuan / only, male child 0.20 / only, the Chinese multi-dimensional 135 yuan / kg, Hua Luo Duowei 140 yuan / kg,[link widoczny dla zalogowanych], imported multi-dimensional 140 yuan / kg, commodity chicken cube 70 yuan / kg. Table 3 test period (ten weeks) breeder diets supplemented with different vitamin discuss the economic analysis of three different vitamin 3.1 on the important breeders have significant effect on production performance. Tests showed that the Chinese multidimensional breeder egg production rate of significant improvement and facilitating role. Chinese multi-dimensional in this study can increase the laying rate 2.51% (compared with imported multi-dimensional.) However, different amounts of Chinese multi-dimensional (ten thousandths and the four ten thousandths) of chicken hatching traits to a certain extent, the best scores to ten thousandths group hatching. The effect on egg production rate did not differ significantly. In the diets of Chinese multi-dimensional, (ten thousandths) significantly increased the profits of chicken raising, which is reflected in the trial of the profit margin per hen higher than 0.02 yuan Hua Luo Duowei group, higher than the import of multi-dimensional one. 85 yuan (see Table 3). In addition, the test, China Luo Duowei chicken hatching traits of a certain role in promoting healthy child and the fertilization rate was the highest, followed by the Chinese multi-dimensional group, the minimum import multi-dimensional group. 3.2 Since the production performance of each experimental group were higher than the multi-dimensional group of commercial chickens, so the chicken cube in this study as control of goods, the marginal benefit analysis used to calculate each test group during the trial period the marginal revenue (J blush) and the marginal cost (MC), from a profit margin (1 of a MC) evaluation of the test group as breeder of the economic benefits. To micro-economics margin analysis showed that diets supplemented with Chinese multidimensional and significant economic benefits (see Table 3). The cost of the increase in the same conditions, feeding commercial layers increase in income came from the broken egg laying rate of increase and decrease in the rate. Is calculated, the marginal profit is positive. Therefore, feeding diets supplemented with commercial layers in the multi-dimensional Chinese have significant economic benefits. Mouth
