Embodiment 1

[0040] In this example, the feed preparation method for 110-210-day-old laying hens will be described. During this period, laying hens need to consume 320 kcal of energy, 17.6 g of crude protein, 360-380 mg of methionine, and 4 g of calcium per day. In this example, the 3% premixed feed LD63 sold by Hemeihua Group was selected as the premixed feed in the feed, and its dosage was used according to the recommended dosage of LD63 products. The feed intake at this stage is 103g / bird / day, and the required amount of methionine should be more than 420mg. Therefore, more than 50mg of methionine should be added, so the content of methionine in Kaisanbao should not be less than 0.25%. The recommended feed formula for 110-210-day-old laying hens is: 65% corn, 22% soybean meal, 2% Kaichanbao, 8% stone powder, and 3% LD63 premix.

Embodiment 2

[0042] In this example, the preparation method of feed for laying hens aged 210-350 days is described: laying hens in this period need to consume 360 ​​kcal of energy, 18.9 g of crude protein, 380-400 mg of methionine, and 3.9 g of calcium every day. In this example, the 4% premixed feed LB64 sold by Hemeihua Group was selected as the premixed feed in the feed, and its dosage was used according to the recommended dosage of LB64 products. The feed intake at this stage is 110g / bird / day, and the required amount of methionine should be above 380mg, so an additional 55mg of methionine should be added, so the content of methionine in Gaochanling should not be less than 0.27%. The recommended feed formula for 110-210-day-old laying hens is: 63.5% corn, 22% soybean meal, 2% Gaochanling, 8.5% stone powder, and 4% LB64 premix.

Embodiment 3

[0044] In this example, the feed preparation method for laying hens aged 350 days to two months before elimination is described: laying hens in this period need to consume 360 ​​kcal of energy, 19.1 g of crude protein, 370-390 mg of methionine, and 4.09 g of calcium every day. In this example, the 3% premixed feed LD63 sold by Hemeihua Group was selected as the premixed feed in the feed, and its dosage was used according to the recommended dosage of LD63 products. The feed intake at this stage is 110g / bird / day, and the required amount of methionine should be more than 370mg. Therefore, more than 45mg of methionine should be added, so the content of methionine in Keliling should not be less than 0.27%. The recommended feed formula for 110-210 day-old laying hens is: 65% corn, 22% soybean meal, 2% Keliling, 8% stone powder, and 3% LB64 premix.

Abstract

The invention belongs to the technical field of poultry farming, and particularly relates to a feed preparation method for improving performance of laying hens in the egg laying period. The problem that in the prior art, the feeding scheme is single in the egg laying period, and consequently the nutritional needs of the laying hens cannot be met at different laying stages and in different laying seasons is solved. As for the current situation, the invention provides the feed preparation method suitable for the egg laying period of the laying hens, the feed preparation method is called as an N+2-2 package, that is, the calculated amount of a nutritional fortifier is added into pre-mixed feed, meanwhile, the corresponding daily ration addition is decreased, and farmers can change the type ofthe nutritional fortifier according to the egg laying stages. Through the research, it is shown that through the laying hen feed prepared through the scheme, the high yield and stable yield of the laying hens can be achieved, the environment-friendly farming requirements for low-protein daily rations can also be met, the energy saving and environmental protection effects are achieved, and the method is simple, convenient and easy to implement and has generalization significance.

Description

technical field [0001] The disclosure belongs to the technical field of poultry breeding, and in particular relates to a feed preparation method for improving the laying performance of laying hens. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] At present, the feed-to-egg ratio of laying hens is generally 2.0:1. The metabolic intensity of laying hens is relatively high, and the production performance of laying hens cannot be fully exerted due to undernutrition. metabolic disease. [0004] At present, the breeding period of laying hens in China is generally about 500 days, and the elimination will be advanced or postponed depending on the market conditions and disease...
