Problems solved by technology

[0003] However, at present, most local breeds of laying hens still lack national unified nutritional standards. In terms of feed preparation, they mostly refer to the nutritional needs of foreign high-yield laying hens. Therefore, the nutritional level is too high, or unbalanced, and there are many types of additives. Local areas are not fully considered. The layer hens have

Embodiment 1

[0013] The mass percentage composition of the feed raw materials for laying hens of local breeds is: corn 63.30%, wheat bran 3.40%, soybean meal 23.00%, vegetable oil 0.60%, stone powder 7.22%, calcium hydrogen phosphate 0.90%, salt 0.35%, 65% lye amino acid 0.02%, methionine 0.10%, 50% choline chloride 0.1%, phytase 0.01%, premix 1.00%.

[0014] Mix the above ingredients evenly to make feed for laying hens of local breeds. The nutritional components of the feed consist of 11.29MJ / kg of metabolizable energy, 15.52wt% of crude protein, 3.04wt% of calcium, and 0.3wt% of available phosphorus . The Beijing oil chickens in the laying period were fed with this feed for 45 weeks (20-65 weeks), with an average egg production of 176 eggs and 5 broken eggs. Beijing oil chicken 45 weeks (20-65 weeks), average egg production 170, broken egg 11, adopt the feed of present embodiment to increase egg production 3.53% compared with commercially available chicken feed (Yukou laying hen feed), ...

Abstract

The invention discloses a feed special for a laying period of a laying hen of a local variety, belonging to the technical field of chicken feed preparation. The feed comprises the following raw materials: 60-65 percent of corns, 2-10 percent of wheat bran, 18-25 percent of bean pulp, 0-1.0 percent of vegetable oil, 4-9 percent of mountain flour, 0.5-1.5 percent of calcium hydrophosphate, 0.2-0.5 percent of table salt, 0.01-0.05 percent of 65 percent lysine, 0.05-0.20 percent of methionine, 0.1-0.15 percent of 50 percent choline chloride, 0.01-0.02 percent of phytase, and 0.5-1 percent of premix. The feed is mainly used specific to the laying period of the laying hen of the local variety; the feed is fed directly in a powder form, so that the feed conversion rate can be effectively improved, the laying peak time can be prolonged, the egg quality can be improved, and the egg broken ratio can be reduced by 3-5 percent.

Description

technical field [0001] The invention belongs to the technical field of chicken feed preparation, and in particular relates to a special feed for laying hens of local breeds during laying period. Background technique [0002] my country is the largest poultry and egg producer in the world, especially the egg output has maintained the first place in the world for many years. At present, more than 80% of the laying hens raised in my country are high-yield laying hen breeds bred abroad, such as Roman Brown, Hessex Brown, Isa Brown, Hailan Brown, Hailan White, etc. The remarkable characteristics of these breeds are egg production. The rate is high, and the average egg production of 72-week-old hens is more than 250 pieces. The local breed layer refers to local chicken breeds in my country, such as Xianju chicken, green-shell layer hen, black-bone chicken and Beijing oil chicken, or egg-type chickens that contain at least 50% of the blood of local chicken breeds in my country.
