Problems solved by technology

And 10,000 chickens can produce 1.3 tons of manure every day, which contains 28% of crude protein and about 200kg of nitrogen, which will cause huge pollution to water quality and land after discharge
How to reduce the environmental pollution caused by laying hen farming has become a current research hotspot. Chicken manure can be fermented to produce ammonia (NH 3 ), indole and other harmful gases have great harm to the respiratory tract of laying hens, cause diseases, and reduce the production performance of laying hens
At the same time, it diffuses into the air and causes air pollution, which affects the surrounding living environment and seriously endangers human health.

Embodiment 1

[0014] A feed for laying hens, in terms of air-dried matter, contains 56% of corn, 17% of soybean meal, 4% of cotton meal, 5% of full-fat rice bran, 6% of bran, 9% of stone powder, 1% of soybean oil, and 1% of calcium hydrogen phosphate %, Methionine 0.12%, Lysine Sulfate 0.05%, Bacillus (10 10 Individual / g): 0.1%, EM bacteria (10 8 pc / g): 0.1%, 0.08% of mulberry leaf extract, and 0.55% of other additives.

[0015] Contain protein 15.25% in the present embodiment, 2% lower than other feedstuffs, metabolizable energy 2600kcal / kg, crude fat 4.22%, crude ash 12.7%, calcium 3.65%, phosphorus 0.06%, methionine 0.38%, lysine 0.73%, The ingredients are well proportioned.

[0016] Compared the formula feed of this embodiment with the control group, the formula of the control group was: fish meal 1%, corn 46.5%, soybean meal 12%, cotton meal 7%, rapeseed meal 7%, full-fat rice bran 13%, stone powder 9%, soybean oil 1.5%, calcium hydrogen phosphate 1%, and other additives 2%, the com...

Embodiment 2

[0020] A feed for laying hens, in terms of air-dried matter, contains 1% of fish meal, 56% of corn, 18% of soybean meal, 2% of cotton meal, 5% of full-fat rice bran, 6.5% of bran, 9% of stone powder, 1% of soybean oil, Calcium hydrogen phosphate 1%, methionine 0.1%, lysine sulfate 0.1%, Bacillus (10 10 Individual / g): 0.1%, EM bacteria (10 8 Piece / g): 0.1%, 0.1% of mulberry leaf extract, and 0.5% of other additives.

[0021] In Taoyuan County, Changde City, Hunan Province, using the formula feed of this embodiment, 10,000 laying hens, 300 days old, by eating this feed for about 2 weeks, compared with other feed breeding users in the surrounding area, the feces odor was significantly reduced, and the laying hens Respiratory diseases are reduced, and the air ammonia concentration in the house is detected to be 2.2%. The air ammonia concentration in the house with other feeds around is 4.21%, which is 48% lower than that in this embodiment.

Embodiment 3

[0023] A feed for laying hens, which contains 1% fish meal, 55% corn, 17% soybean meal, 2% cotton meal, 6% full-fat rice bran, 7% bran, 9% stone powder, 1% soybean oil, and Calcium hydrogen phosphate 1%, methionine 0.1%, lysine sulfate 0.1%, Bacillus (10 10 Individual / g): 0.1%, EM bacteria (10 8 Piece / g): 0.1%, 0.1% of mulberry leaf extract, and 0.5% of other additives.

[0024] In the area of ​​Hanshou County, Changde City, Hunan Province, using the formula feed of this embodiment, 10,000 laying hens, 240 days old, passed the feeding of this feed for 10 days, the temperature in winter was low, the chicken house was closed, and there was no obvious odor, and the feces were collected and tested Indole 1.21mg / kg, skatole 35.45mg / kg, ammonia 2.04%.

Abstract

The invention relates to a chicken feed, in particular to a layer feed. A high-efficiency environment-friendly layer feed contains 15 to 15.5 percent of protein, and comprises the following components: an animal protein source, a plant protein source, a fat source, methionine, lysine, mineral substances, a vitamin additive, bacillus, EM bacteria and a mulberry leaf extract. By adding the methionine and the lysine, the protein content of the feed is reduced to 15-15.5 percent, and the nitrogen emission in manure of layers can be effectively reduced; meanwhile, the added bacillus and the EM bacteria can decompose and utilize substances such as indole, proteins, ammonia in the manure, the nitrogen emission in the mature and the discharge of harmful gas such as ammonia gas (NH3) and indole are reduced, and the nutritional value of eggs cannot be influenced.

Description

【Technical field】 [0001] The invention relates to a feed for chickens, in particular to a feed for laying hens. 【Background technique】 [0002] With the improvement of the intensification of laying hens, the pollution of the environment caused by feeding commercial feed is becoming more and more serious. The current measurement shows that 200,000 laying hens pollute the air with a diameter of 500 meters through ammonia gas. And 10,000 chickens can produce 1.3 tons of feces every day, which contains 28% crude protein and about 200kg nitrogen, which will cause huge pollution to water quality and land after discharge. How to reduce the environmental pollution caused by laying hen farming has become a current research hotspot. Chicken manure can be fermented to produce ammonia (NH 3 ), indole and other harmful gases have great harm to the respiratory tract of laying hens, cause diseases, and reduce the production performance of laying hens. At the same time, it diffuses into t...
