Problems solved by technology

[0007] The technical problem solved by the present invention is to overcome the defects such as no pre-egg production peak feed or unscientific, incomplete, and poor effect during the peak climbing stage (pre-laying stage) of the existing laying hen feeding process. 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

Abstract

The present invention discloses a laying chicken reproductive performance improving material in the egg laying peak prophase and a preparation method thereof, which belongs to the technical field of feed composition. The material in the egg laying peak prophase is prepared by scientifically blending plant extract, corn bee pollen extract, Chinese herbal medicine extract, modified dietary fiber, prebiotic factors, etc. The feeding trial showed that compared with the commercially available egg laying peak phase material, the oviduct lengths of laying chickens are 6.82 cm and 4.62 cm respectively; the oviduct weights increase by 11.49 g and 7.46 g respectively; the ovary weights increase by 6.08 g and 4.17 g respectively; the egg laying rates increase by 2.07% and 2.15% respectively; egg productions increase by 2.73 g and 1.92 g respectively; the tibia lengths are 7 mm and 5 mm; the weights improve by 0.07 kg and 0.05 kg respectively; and the survival rates increase by 2.4% and 3.2%. The laying chicken fed by the material in the egg laying peak prophase shows relative strong reproductive performance, production performance, anti-immunity 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-peak feed for improving the reproductive performance of laying hens and a preparation method thereof. Background technique [0002] The feed in the early stage of egg production peak is the feed used by laying hens during the period from 5% egg production rate to the peak egg production period (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 tends to be steep. Like a mountain, it rises rapidly from bottom to top. 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 ...
