Problems solved by technology

[0007] The technical problem solved by the present invention is to overcome the defects such as the lack of pre-egg production peak feed or the unscientific, incomplete, and poor effect of the pre-egg production peak feed during the peak climbing stage (pre-laying stage) of the existing laying hens. The special physiological and growth characteristics of laying hens at the peak stage are based on the physiological needs and nutritional needs of laying hens during the peak climbing period. The reproductive performance, immunity, disease resistance, nutrition and digestibility of plant extracts, corn bee pollen extracts, Chinese herbal medicine extracts, modified dietary fiber, and probiotics are used to prepare a kind of egg production peak early to promote reproductive performance the feed

Abstract

The invention discloses a feed for promoting the reproductive performance and used in the earlier stage of a peak laying period, belonging to the technical field of feed composition. Plant extracts, corn bee pollen extract, Chinese herb extracts, modified dietary fiber, prebiotics factors and the like are scientifically compounded in the laying hen feed used in the earlier stage of a peak laying period and thus the feed for promoting the reproductive performance is prepared; through feeding experiment, the feed disclosed by the invention and the commercially available feed used in the peak laying period respectively have the following beneficial effects: the length of the fallopian tube of the laying hen is 6.82cm and 4.62cm respectively, the weight of the fallopian tube is improved by 11.49g and 7.46g respectively, the weight of ovary is improved by 6.08g and 4.17g respectively, the laying rate is improved by 2.07% and 2.15% respectively, the egg yield is improved by 2.73g and 1.92g respectively, the shank length is 7mm and 5mm respectively, the weight is improved by 0.07kg and 0.05kg respectively and the survival rate is improved by 2.4% and 3.2% respectively; the laying hen has strong reproductive performance, strong production performance, strong immunity resistance and disease resistance.

Description

technical field [0001] The invention belongs to the technical field of feed compositions, and in particular relates to a feed for promoting reproductive performance in the early stage of egg production peak and a preparation method thereof. Background technique [0002] Climbing feed is the feed used by laying hens from 5% egg production rate to the peak period of egg production (that is, 5% egg production rate-32 weeks of age). At this stage, the egg production rate rises rapidly, and the egg production rate curve moves like a steep mountain. , from bottom to top, rising rapidly. At the same time, the weight of laying hens increases rapidly, the reproductive system also develops rapidly, the follicles on the ovaries grow rapidly, the oviducts also become thicker and longer, and the weight increases. . Weight gain and reproductive system maturation occur simultaneously. At this time, some chickens began to lay eggs, and the egg production rate of well-developed chickens r...
