Egg feed costs account for approximately 60% to 70% of total expenditure. To improve the economic efficiency of laying hens, we must start with saving feed. Selection of breeder chicken laying hens should use varieties with small body weight and high feed utilization rate, and the same breed should have medium weight; the same amount of eggs is produced, and large-bodied chickens with smaller specific weights consume more material. The practice of raising the cage cage causes a stable environment, a small amount of activity, and a large breeding density, which reduces the amount of heat dissipation and therefore reduces the amount of food consumed. According to calculations, the ratio of cages to rearing can generally save 20% to 30% of feed. Turn off the good feed and feed the mildewed feed to ensure the full price of the feed, because nutrition is not the biggest waste. The feed must not be crushed too much, otherwise it may easily lead to difficulties in eating and be wasted due to the flying of dust. According to seasonal ingredients, chickens consume more calories in winter, and the proportion of energy feed should be appropriately increased (65% to 70% of total feed should be appropriate), and the proportion of energy feed should be appropriately reduced in summer. 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. Ensuring sufficient drinking chickens consumes 340 ml of water per egg. If there is a lack of water during egg production, egg production can be reduced by 30%. To improve the feed trough structure to feed chicken troughs, should be the bottom tip, belly, mouth small. Because of the large amount of material in such a chute, the chicken is not easy to pick it up and eat it. The trough height should be based on the chicken's free intake. The amount of added material should not be too full. Generally, it should be controlled at 1/3 of the tank height. Otherwise, it is easy to throw and waste. Deworming in time If there are parasites in the chicken, the nutrients converted by the chicken's feed will be absorbed by parasites, causing the consequences of "seemingly raising chickens, but actually keeping them up." Therefore, chickens should generally be repelled once in 30-60 days. Timely elimination of rooster cocks generally eats 20% to 25% more feed than hens. Therefore, excess roosters should be eliminated in time; breeder chickens should be maintained at a ratio of 1:15 for males and females and 1:1 for commercial layers. 20 is appropriate. Elimination of low-yielding hens often has 10% to 30% of low-yielding chickens. The elimination of low-yielding chickens will not result in significantly less egg production, and feed can be significantly saved.
