Problems solved by technology

[0007] The technical problem solved by the present invention is to overcome defects such as no pre-egg-laying feed or unscientific, incomplete, and poor effect in the peak-climbing stage (pre-laying stage) of the existing laying hen feeding process. According to the peak-climbing stage The special physiological and growth characteristics of laying hens are mainly based on the physiological and nutritional needs of laying hens during the peak climbing period; the main goal is to efficiently promote the development of reproductive organs (fallopian tubes, ovaries) of laying hens. Reproductive, immune, disease resistance, nutritional and digestible plant extracts, corn bee pollen extracts, Chinese herbal medicine extracts, modified dietary fiber, and prebiotic factors are used to prepare a product that can effectively promote the development of reproductive organs of laying hens.

Abstract

The present invention discloses pre-laying feed for promoting the development of reproductive organs of laying hens and a preparation method thereof, and belongs to the technical field of feed composition. The feed is prepared by scientifically compounding pre-laying feed for the laying hens with plant extracts, corn bee pollen extracts, herbal extracts, modified dietary fibers, prebiotic factors, etc. The feeding experiment shows that: compared with the commercially available egg laying peak feed, the feed makes tubal lengths increased by 6.82 cm and 4.62 cm respectively; oviduct weight increased by 11.49 g and 7.46 g respectively; ovary weight increased by 6.08 g and 4.17 g respectively; egg laying rates increased by 2.07% and 2.15% respectively; egg weight increased by 2.73 g and 1.92 g respectively; tibia lengths increased by 7 mm and 5 mm; weight increased by 0.07 kg and 0.05 kg respectively; and survival rates increased by 2.4% and 3.2% respectively; suggesting that the laying hens have strong reproductive performance, egg production performance, immunity improvement performance and disease resistance performance.

Description

technical field [0001] The invention belongs to the technical field of feed compositions, and in particular relates to a pre-laying feed for promoting the development of reproductive organs of laying hens 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 rea...
