16-week-old-2% laying hens use crown-throwing feed

Abstract

The divisional application of the invention discloses a comb growth feed achieving comb growth consistency and increasing laying rate for laying hens of 16 weeks and with laying rate of 2%, belonging to the field of feed compositions. The feed is used for the laying hens of 16 weeks and with laying rate of 2%, and can promote the propagative organ development and weight gaining; the feed is mainly prepared from the following raw materials in parts by weight: 54.365 parts of corn, 3 parts of rice bran, 2.5 parts of wheat bran, 14 parts of bean pulp, 3 parts of fermented soybean meal, 3 parts of peanut meal, 2.8 parts of sunflower seed meal, 2 parts of rapeseed dregs, 3.5 parts of distillers dried grains with soluble (DDGS), 3 parts of corn bran, 1.0 part of soybean oil, 5.2 parts of mountain flour, 0.8 part of calcium hydrogen phosphate, 0.35 part of table salt, 0.13 part of methionine, 0.12 part of 70% lysine sulfate, 0.05 part of probiotics, 0.05 part of a complex enzyme preparation, 0.012 part of phytase, and 1 part of a compound premix. By using the feed, the comb growing consistency in a comb growth phase, large eggs in a preliminary egg laying stage, fastness in speed of reaching the egg laying peak, and the relatively high laying rate can be achieved.

Description

[0001] This application is a divisional application, the original application number: 201310061331.1, the application date: 2013-02-25, the name of the invention: the application method and feed of laying hen nutrition package with high egg production. technical field [0002] The invention belongs to the field of feed composition and feeding, and in particular relates to a feed composition and a feeding method for promoting the growth of reproductive organs and body weight of laying hens (16-week-old-2% egg production rate). Background technique [0003] At the age of 16-28 weeks, commercial laying hens have special physiological characteristics such as rapid weight growth and rapid development of reproductive organs. There is a physiological anorexia period, and the feed intake is insufficient, but the nutrients needed for egg production growth, weight gain, and rapid maturation of reproductive organs High, resulting in a huge stress response, leading to five major problems...

Problems solved by technology

[0006] Third: the peak is slow, the peak is not lasting, and the egg weight is not ideal (adjustment, reserve);

[0008] Fifth: Inexplicable death (development, reserve), great stress, high death rate

The reason for the gap is not only insufficient nutrient concentration of the feed, but also poor division of feeding and management stages. Some feed factories directly feed the peak egg production feed at 16 weeks old, the feeding amount is not accurate enough, and the feed intake is not enough. Many reasons

[0010] At present, the egg-laying peak feeds on the market are basically layer feeds that start to be used from 16 weeks to 72 weeks. The needs of chickens at special physiological stages before laying and at the peak cause huge hidden losses in chicken farms, which are manifested in high death rate, low egg production, short feeding cycle, and some are eliminated at 65 weeks old
