Xin Yang black laying hen egg producing period feed and breeding method

Abstract

The invention discloses Xin Yang black laying hen egg producing period feed and a breeding method. According to a physiological characteristic of a Xin Yang black hen at each stage, feed for three growth stages is set: egg producing period feed for 16 to 30 weeks old, egg producing period feed for 31 to 55 weeks old, and egg producing period feed for 56 to 72 weeks old; different nutritive indexesare required for each growth stage. According to the feed provided by the invention, the components are matched, and when the feed is used as the Xin Yang black laying hen egg producing period feed,an egg laying performance of the Xin Yang black hen can be improved, and the breeding cost is reduced.

Description

technical field [0001] The invention relates to a feed for chickens, in particular to a feed and a feeding method for new poplar black layer hens during laying period. Background technique [0002] With the continuous development of feed industry and animal husbandry, the output of feed increases, and the problem of shortage of raw materials is becoming more and more serious. For this reason, the country has developed a new breed of new poplar black layer hens with low feed intake. "Xinyanghei" laying hens have black feathers, black feet, and five toes. They are beautiful in shape and have a high egg production rate. At 72 weeks of age, they can lay more than 290 eggs. The egg production rate can reach more than 90% during the peak period and can last for more than one month. ; "Xinyanghei" eggs are small in weight, the average egg weight is less than 50 grams, and the egg breakage rate is low during long-distance transportation.

Problems solved by technology

[0003] Yang Jian and others from the National Poultry Engineering Technology Research Center of the Institute of Animal Husbandry and Veterinary Medicine of the Shanghai Academy of Agricultural Sciences published the "Key Points of Feeding and Management of "New Yanghei" Layers During Laying Period", but in actual production, according to the egg production in this document New Yanghei laying hens are fed with long-term feeding and management methods. The egg production performance of Xinyanghei is not ideal. The egg production rate of 80% lasts for about one month, and the egg production rate of 90% is less than one week. Most of the time The egg production rate is maintained above 70%, which is quite different from the breed standard

The inventor of the present application investigates its reason and finds that the nutritional index of the feed cannot meet the needs of laying eggs, and the feed configuration carried out by the nutritional standard (see Table 1) recommended by Xinyanghei is unscientific
