Broiler "flowing" rapid feeding method

Quick-feeding of broiler chickens means that the broilers are reared in brooding and rearing, that is, the chicks are raised in the broiler house until they are 4 weeks old, and then transferred to the rearing house for rearing. This way, the broilers are accelerated to turn around the broilers. The batches also increased the utilization rate of chicken houses and reduced the occurrence of epidemics. The economic benefits were quite significant. Practice has proved that this feeding method can raise 8 to 9 batches of broiler chickens a year, and brooding, rearing with the same housing, can only raise 4 to 5 batches a year. The breeding method is described as follows:

1 variety selection

At present, the main fine inner chicken breeds are: Aviin, Kaunis, AA, Star and Red Jade. These species have high survival rate (up to 95% to 98%), rapid growth (up to 2 kg in 8 weeks of age), low consumption of material (feed ratio 1.8 to 2.1), and feeding throughout the year, etc. Advantages, breeders can choose according to local conditions.

2 chicken house disinfection

The area ratio of the brooding house and the finishing house is generally 1:2. The brooding houses can be replaced by ordinary houses, and they can be used after they are trimmed, cleaned and painted. The fattening house uses a wall outside the house and builds the remaining three sides with bricks or slabs. It requires a height of 2 to 2.5 meters. The length and width can be determined according to the amount of rearing, and the front and rear windows and the top are set. The brooding house and the finishing house must be disinfected before each batch of feeding. The method is: first clean the house, and then use 2% to 2.5% caustic soda water spray disinfection, and then press formalin per square meter of space to add water 14ml, into the container, will be 14 grams of potassium permanganate Put into it, you can carry out fumigation, close the doors and windows a week later, and then free for 2 to 3 days, you can start feeding.

3 diet formula

Diets for broilers should be high-energy, high-protein, full-priced feeds, with various proportions of nutrients being appropriate. 1 to 4 weeks of age require diets containing 2900 to 3,000 kcal per kilogram of metabolic energy and 22% to 23% of crude protein; 5 to 8 weeks of age require kilograms per kilogram of dietary energy to be 3100 to 3200 kcal, including Protein 19% to 20%. The diets may consist of corn (2428, -1.00, -0.04%), sorghum, barley, wheat, rice bran, bran, soybean (4807, -13.00, -0.27%), peas, hummus, rapeseed (5219, -6.00, -0.11%) cake, cottonseed cake, peanut cake, bean cake, silkworm cocoon, fish meal, blood meal, bone meal, shell powder, etc. 1 to 4 weeks old reference formula: corn meal 53.7%, bran 2%, bean cake meal 22%, cottonseed cake meal 6%, rapeseed meal meal 6%, fish meal 6%, bone meal 2%, shell powder 2%, salt 0.3%, and 0.25 kg of selenium auxin, 0.25 kg of multivitamin, and 100 olaquindox (crushed) were added for every 50 kg of feed. 5 to 8 weeks old reference formula: corn meal 57.7%, bran 4%, bean cake meal 23%, cottonseed cake meal 6%, fish meal 5%, bone meal 2%, shell powder 2%, salt 0.3% (additives Ibid.)

4 Reasonably feeding

In the first two days of the broiler's broiler's broiler's house, the chicks can be fed with broken rice or corn grits, and fed with cooked egg yolks (3 egg yolks per 100 chicks); on the 3rd day, feed the compound feed. For chicks aged 1 to 2 days, the feed meal was sprinkled on plastic (10155, -230.00, -2.21%) cloth and fed once every two hours; the feed flour was added within 3 to 10 days of age. Appropriate amount of water (with fingers not dripping) is steamed and fed to facilitate digestion and absorption of chicks; after 10 days of age, dry feed meal can be fed directly into strip feeders, and the number of feed troughs is much higher. No less, so that each chicken can eat at the same time, feeding 6 times a day; after 20 days of age (when the body weight reaches 0.25 kg or more), dry powder for the whole day, any chicken free to eat. At the same time, provide plenty of clean drinking water.

5 Careful management

For the first time, it is necessary to maintain proper temperature and humidity. In the first few days, the temperature in the house should be maintained at 35 °C ~ 32 °C, then down 3 °C every week, until it has dropped to about 20 °C. With suitable temperature, broilers are not susceptible to disease and grow faster. The humidity should not be too large, otherwise the bacteria and eggs will be easy to reproduce. The chickens are susceptible to aspergillosis and coccidiosis. Suitable relative humidity for broilers is: generally maintained at 65% to 70% in the early stage and about 55% in the latter stage. House humidity can be used for hygrometer determination. Second, do a good job of ventilation. The simple method of ventilation is to build a sunroof on the top of the house, or to open the window before and after, so that the air convection, but also can install a two-way fan. In a well-ventilated chicken house, people feel no ammonia smell and no pungent glare. Third, reasonable lighting and breeding density. The purpose of broilers to light is to extend the time of eating and speed up the growth. Experience has shown that it is best to give light 24 hours a day, and the light intensity is slightly stronger in the first 3 days to facilitate chicks to become familiar with the environment and gradually weaken afterwards so that the chicken can see the food. The reasonable rearing density per square meter is: 30 to 32 for 1 to 4 weeks of age and 14 to 16 for 5 to 8 weeks of age. Fourth, we must be diligent. The litter can be sawdust, glutinous rice, short straw, etc. Sand can also be used in summer. During the entire feeding period, litter is added as needed, and the matted litter can be used after being fluffed and loosened. In addition, we must promptly do a good job in the size, strength, and division of work, and constantly eliminate sick, weak, miscellaneous chickens, and carefully care according to their different circumstances to promote consistent growth of chickens. The brooding house can be used with 250-300 flocks, and fattening contains 400-500 flocks.

6 Disease Prevention and Control

Keepers should do a good job of personal hygiene and wear work clothes and hats. Keep the brooding house, the finishing house and the surrounding environment clean and hygienic, so that the chicken body, feed, drinking water, food utensils, tools and litter are all six clean. It is strictly forbidden that personnel enter the shed to prevent the introduction of human germs. In addition, drug prevention and treatment measures, etc., are the same as those raised by ordinary methods.
