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 of the pre-laying feed during 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 ...

Abstract

The invention discloses feed for promoting the development of the ovary and the fallopian tube of a laying hen and a preparation method of the feed, and belongs to the technical field of feed composition. The feed provided by the invention is prepared by scientifically adding plant extracts, corn bee pollen extracts, Chinese herbal medicine extracts, modified dietary fiber, one or more prebiotic factors and the like into early laying period chicken feed. Feeding tests show that compared with laying hens fed with two types of peak-laying feed sold in market, the laying hen fed with the feed provided by the invention has the advantages that the length of the fallopian tube is improved by 6.82 cm and 4.62 cm respectively; the weight of the fallopian tube is improved by 11.49 g and 7.46 g respectively; the weight of the ovary is improved by 6.08 g and 4.17 g respectively; the egg laying rate is improved by 2.07% and 2.15% respectively; the egg laying quantity is improved by 2.73 g and 1.92 g respectively; the shank length is improved by 7 mm and 5 mm respectively; the body weight is improved by 0.07 kg and 0.05 kg respectively; the survival rate is improved by 2.4% and 3.2% respectively. Therefore, the laying hen fed with the feed provided by the invention has higher reproductive performance, production performance, anti-immunity, and disease-resistant performance.

Description

technical field [0001] The invention belongs to the technical field of feed compositions, and in particular relates to a feed for promoting the development of ovaries and oviducts 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 reached 3-5% ...
