There are wonderful ways to increase weight in broiler breeding.

There are white-feathered broilers and yellow-feathered broilers. The growth period of white-feathered broiler is 42 days, and the general incubation period is 21 days, while yellow-feathered broiler is a free breed in China. Although it grows slowly, it has good meat quality and flavor. There are more breeding in southern China, the incubation period is 21 days, and the growing period is 60 days, 90 days and 120 days.

The management of broilers should be proper in order to reduce the occurrence of diseases in the growth process of broilers, and should not be relaxed from the beginning of feeding to the later stage of management.

1. The usual time for eating is 8-12 hours after coming out of the shell. Spread the plastic sheeting on the floor, sprinkle the mixed feed on the plastic sheeting, gently tap the cloth noodles with your fingers, and induce the chicken to eat for 20: 30 minutes each time. When you are 80% full, take off the plastic sheet and let it have a quiet rest, and then feed it every 2 hours, so that all the chicks learn to peck on the first day (1-3-day-old chickens, soak in boiled water, add oxytetracycline and multivitamin, or use fried chopped rice as food).

2, feeding, regular and quantitative feeding, 4 times a day, dry feeding can be used in the feeding process, as long as regular formula feed is added to the trough, green feed is fed separately. Wet feeding is to mix the formula feed, green feed and water and then feed.

427-day-old feed formula: corn 65%, wheat bran 4%, bean cake 14%, fish meal 9%, blood meal 4%, bone meal 2%, shell powder 2%, salt 0.3%, growth promoter 0.2%. In addition to feeding compound feed, it is also appropriate to add fresh materials, excipients and green fodder to make chickens eat better.

3. Drinking water, drinking water can be carried out at the same time as eating, but it is best to feed water before eating, feeding 0.01% potassium permanganate aqueous solution or 10% sugar water for the first time. At the age of 1-15 days, it is best to feed warm boiled water.

4. Management, chicks should have a good grasp of temperature, humidity, density and light before they are 4 weeks old. The suitable temperature was 34 ℃ at the age of 4 days, 32 ℃ at the age of 5 days and 7 days, and then decreased by 2 ℃ per week to 20 ℃. The relative humidity at the age of 3 weeks was 65% 70% and 55% 60% after the age of 3 weeks. The feeding density was 40 birds per square meter at the age of 1 week and 2 weeks, and 25 birds at the age of 3 weeks and 4 weeks. The sunshine time is not less than 16 hours per day. After the chicken has grown to the age of 4-5 days, pay attention to the ventilation in the chicken house and open the window properly to let the chicken bask in the sun.

How to gain weight for chickens in winter

1. The method of adding methionine added 4 grams of methionine and a small amount of microbiotics to every 5 kg chicken feed, the weight gain was faster.

2. The method of feeding aseptic fly maggot uses distiller's grains as raw material to produce 500 grams of fresh fly maggots to feed broilers, which can increase the weight by 0.9 kilograms.

3. Adding soybean oil can make the broilers fat and tender by adding a little raw soybean oil to the chicken feed 7 days before the sale of broilers.

4. The fat chicken powder was prepared by adding fat chicken powder according to the dosage of 20% dried ginger powder, 9% licorice powder, 7% fennel powder, 50% cinnamon, 6% cooked soybean powder and 8% ferric sulfate. Each chicken was 0.5 kilogram at a time, mixed with water and fed once every two days.

5. Feed a chicken with cooked cornmeal 200 grams of cooked cornmeal every day. Artificial feeding is divided into three times in the morning, noon and afternoon, and the effect is better by adding some green vegetable leaves appropriately.

6. Three days after feeding the chicks fed with multi-enzyme tablets, 0.04% polyacid tablets were added to the solar eclipse and fed for two weeks.

7. Feeding moxa powder adding 2% moxa powder to broiler diet can increase daily gain by 10% to 20%.

The above is for everyone to introduce the management mode of weight gain from the beginning of eating to the later stage of weight gain. As the saying goes, do not fight an unprepared battle, lay the foundation for the growth needs of broilers in the early stage, and then use the way of weight gain in the later stage, the effect is better.
