High feed prices save the doorway - reduce the cost of feed for laying hens 15 strokes
The cost of feed for laying hens usually accounts for 60%-70% of the total expenditure, while the amount of feed waste accounts for 3%-8% or more of the total feed consumption, which is more than 10%. Therefore, conservation of feed can significantly improve the economic efficiency of laying hens.
1. Selection of breeder chicken laying hens should use varieties with small body weight and high feed utilization rate; the same species should be medium weight. The same amount of eggs is produced, and large-sized chickens consume more material than the smaller ones.
(2) Cutting off razor clams at the age of 6-9 days of chicks not only can effectively prevent the emergence of fleas, but also can save 3.5 grams of feed per day during the growth period and save 5.5 grams of feed during the laying period; Eggs save 12 grams of feed.
3. The implementation of a cage raising cause of environmental stability, a small amount of activity and a high density of breeding, reducing the amount of heat, so the corresponding reduction in food consumption. It is estimated that the ratio of cages to rearing can generally save 20% to 30% of feed.
4. The protection of feeding the most suitable chicken egg-laying temperature is 13-21 °C. In winter, the house temperature is lower than 8°C, and every 100 chickens eat 1.5 kg of feed each day, and the egg production rate is decreased. In summer, the chicken feed intake is reduced, but the egg production rate is also reduced. Therefore, protective measures should be taken in production, summer cooling should be taken care of, and winter should be warm and warm, provide suitable environmental conditions for the growth of chickens, not only conducive to multiple eggs, but also help save feed. According to experiments, the chicken house temperature was appropriately increased in the winter, and each chicken could save 3.1 grams of excess protein per day.
5. The good feed should not be fed with mildewed feed to ensure the feed's full price nutrition, because the incomplete nutrition in the feed is the biggest waste. Feed crushing can not be too fine, otherwise it will easily lead to feeding difficulties and waste of “dust†flying.
6. According to seasonal ingredients, chickens consume more calories in winter, and the proportion of energy feeds should be appropriately increased (65%-70% of the total amount of feed is appropriate); the proportion of energy feeds should be appropriately reduced in summer.
7. The use of alternative protein feeds, especially fishmeal, is expensive, with some cheap insects, cockroaches, local fish, shrimp, meat processing by-products, fish waste, powder residue, sugar residue, bean curd residue, distiller's grains Such as, after appropriate processing and modulation to replace part of the protein feed to feed chickens, can greatly reduce the cost of feed.
8. Use of Feed Additives The use of additives can increase the utilization of protein feed and also help reduce feed costs. It has been reported that adding 0.1% methionine to common feeds can increase the utilization of feed protein by 2% to 3%; adding lysine can reduce 3% to 4% of the feed crude protein dosage; add vitamin B12 and quinoline Ethanol and other feed additives can also improve the utilization of crude protein in feed.
9. Adding vitamin C to 50 grams of vitamin C per ton of chicken feed can increase egg production by more than 10% and save more than 15% of feed.
10. Adding grit to grit once a week The grit will help grind the feed in the stomach and stomach, aid in digestion and absorption, and increase the feed digestibility by 3%-8%.
11. Improve the feed structure of the feed to feed chickens, it should be the bottom tip, large belly, small mouth. Because of the large amount of material contained in this kind of material, chickens do not easily pull out the feed, so that the chicken can eat the net leftovers. As regards the height of feedstuffs, the main criterion for chickens to eat freely should be adopted. The amount of material added to the feed should not be too full. Generally, it should be handled at 1/3 of its height. Otherwise, it will be easily thrown and wasted. According to reports, when feed is added to 2/3 of the material, 12% of the feed is wasted and it is wasted at 1/2. 5%, wasted 2% when added to 1/3.
12. Ensure adequate drinking chickens consume 340 ml of water per egg; if there is water shortage during egg production, egg production can be reduced by 30%.
13. Deworming in time If the chicken has parasites, the nutrients converted by the chicken's feed will be absorbed by the parasite, causing the consequences of "seemingly raising chickens, but actually keeping them up." Therefore, chickens should generally be repelled once in 30-60 days.
14. Timely elimination of cockerel cocks generally eats 20%-25% more feed than hens. Therefore, excess cocks should be eliminated in time; breeder chickens should be kept at a ratio of 1:15 for males and females; : 20 is appropriate.
15. Elimination of low-yielding hens Often 10% to 30% of low-yielding chickens are culled from low-yielding hens. The elimination of low-yielding chickens will not result in a significant reduction in egg production, but it can significantly save feed.
