Abstract
The invention relates to a premix and a feed for improving the fertility of broiler breeders and application thereof. The premix comprises the following components in parts by weight: 1-8 parts of resveratrol, 10-30 parts of abelmoschus manihot, 5-30 parts of tributyrin, 5-12 parts of vitamin E, 2-5 parts of apple pectin oligosaccharide, 25-5 parts of hydroxy vitamin D31, 1-5 parts of canthaxanthin and 20-60 parts of rice chaff. The feed comprises the following components in parts by weight: 50-100 parts of corn, 1-10 parts of soybean oil, 10-30 parts of soybean meal, 5-15 parts of calcium carbonate, 1-5 parts of calcium hydrophosphate, 0-0.5 part of sodium chloride, 0.1-0.5 part of choline chloride, 0-1 part of compound multivitamin, 0.1-1 part of mineral premix, 0.1-0.3 part of L-lysine sulfate, 0.1-0.5 part of DL-methionine, 0.01-0.1 part of threonine, 0.05-0.5 part of baking soda and 0.1-1 part of premix.
Description
Technical Field
The invention belongs to the technical field of feed preparation, and particularly relates to a premix for improving the fertility of broiler breeder chickens, a feed and application thereof.
Background
Poultry farming is one of the industries with the highest degree of intensification and socialization in the animal husbandry in China, and the development of poultry farming directly influences the health and economic development of the nation. The AA broiler breeder is bred by America Avicey company, the offspring has the characteristics of high survival rate, high meat yield, high weight gain speed and the like, the number of qualified eggs produced by the father and mother generations is high, and the fertility rate, the hatching rate and the hatched healthy chickling rate are increased in different degrees. The breeding period of AA parental breeding hens is 448 days, the egg laying accumulation of the hens in the shed is 184.5, and the qualified breeding eggs are 176.9. The laying rate of the egg is 5.3 to 13.6 percent at the age of 175-182 days, the laying rate of the egg only reaches 87.7 percent in the week and the laying rate of more than 80 percent can only be maintained for about 9 weeks in the egg-laying peak period. The results of the previous studies showed that even in the absence of other diseases, a small fraction (8.48%) of broiler hens maintained very high laying rates, a fraction (41.89%) had slightly poor productivity, maintained at an average level, and a fraction (36.83%) of broiler breeders had poor productivity, significantly below the average level. Poultry possesses 480 ten thousand primary follicles, but ovulate 500-1000 for life, poultry follicles are less than 1 ‰ capable of finally developing, maturing and ovulating, most follicles cannot be developed and remain silent or die through autophagy, apoptosis and other unknown pathways, and a part of follicles are killed during development due to granulosa cells under stress or disease to form follicular atresia. The growth and development of the follicle are a complex regulation process, and are regulated by a plurality of factors, so that the growth and development of the follicle of the poultry are promoted, the probability of atresia of the follicle of the poultry is reduced, the egg producing period of the poultry is prolonged, and the egg producing rate is improved. Studies have shown that follicular atresia due to various stress factors is responsible for the poor reproductive performance (egg production levels) of poultry. And earlier researches show that the differences of intestinal canal structure forms, intestinal canal microbial community structures and follicular development conditions of laying hens with different egg laying levels are obvious, which shows that the reproductive performance of the laying hens can be improved by regulating and controlling the intestinal canal function, improving the absorption of nutrient substances and reducing the atresia of follicles. Therefore, a nutrition regulation and control technology for improving the intestinal microbial structure of the low egg laying performance broiler breeder through the feed, reducing follicular atresia and improving the production performance of the broiler breeder needs to be constructed.

Example 4
1120 AA broiler breeders with the age of 48 weeks are selected in the experiment and are treated in 7 ways, wherein the treatment is as follows: basal feed group (CON: basal diet); and (3) treatment 2: the feed of example 1; and (3) treatment: feed of example 2, treatment 4: feed of example 3, treatment 5: feed of comparative example 1, treatment 6: feed of comparative example 2, treatment 7: the feed of comparative example 3,8 replicates per treatment, 20 chickens per replicate, with a test period of 8 weeks. The experimental basic feed is corn-soybean meal type powder, is prepared according to NRC (1994) and Chinese chicken feeding standard 2004, and the nutrient level in the basic feed can meet or exceed the nutrient requirement of the broiler breeder in the period. The daily formula is shown in table 1. The breeding method comprises the following steps: the feed is prepared by mixing 150g-160g per day in two times: at 30 am and 30 pm and 4 pm, the broiler breeder chickens of the present example were given free water during the breeding process, while controlling the henhouse temperature at 22 ℃ and the relative humidity below 75%.
The test results are shown in tables 2 to 4.
TABLE 1 basic ration composition (air dry basis)
TABLE 2 influence of the premix according to the invention on the performance of broiler breeder breeders
Note: the letters a, b, c in the same column are different and mean that the difference is significant (P < 0.05).
As shown in table 2, the results show that: compared with a control group, the premix added into the basic feed can improve the laying rate and the hatching egg qualification rate of broiler chickens (P is less than 0.05), reduce the feed-egg ratio (P is less than 0.05) and improve the feed utilization efficiency of broiler chickens (P is less than 0.05).
TABLE 3 Effect of the premix according to the invention on the reproductive performance of broiler breeder chickens
As shown in table 3, the results show that: compared with a control group, the addition of the premix of the invention in a basic diet (CON) group improves the fertility rate, the hatchability rate and the healthy chick rate of hatching eggs and reduces the dead chick rate (P < 0.05). The feed of the invention can improve the reproductive performance of broiler breeder chickens.
TABLE 4 Effect of the premix according to the invention on the number of follicles in broiler breeder chickens
As shown in table 4, the results show that: addition of this premix in basal diet (CON) group increased the number of secondary follicles (P <0.05), decreased the number of atretic follicles (P <0.05) relative to control group.
Example 5
The effect of basal diet, the feeds of example 1 and example 2 on ovarian apoptosis-related gene expression was evaluated using fluorescent quantitative PCR. Since the method belongs to a relatively mature assessment method, the specific operation steps are not described in detail.
The mature follicle mainly comprises egg yolk, oocyte, granular cell layer, membrane cell layer and the like. The granular cells are connected with the oocytes through gap junctions, can exchange substances with the oocytes, and play a role in determining fate of quiescence, activation, death and the like of the oocytes. Proliferation, differentiation and apoptosis of granulosa cells determine the recruitment, selection and atresia of follicles. Human and murine studies have demonstrated that the apoptotic mode of the mitochondrial pathway is the predominant form of granular apoptosis. Apoptosis of the mitochondrial pathway is a complex process of co-action of pro-apoptotic proteins (Bax, Bim) and anti-apoptotic proteins (Bcl-2) with the apoptosis performer Caspase family (3,8,9), where increased expression of caspases 3 and 9 is thought to reflect markers of apoptosis and follicular atresia of follicular granulosa cells. As shown in fig. 1, the results show that: the addition of the premix of example 1 of the present invention to the basal diet (CON) group reduced the relative expression levels of the pro-apoptotic genes Caspase 3,8 and Bax (P <0.05), and increased the expression of the anti-apoptotic gene Bcl-2 (P <0.05) relative to the control group.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
