Four suggestions for autumn and winter broiler

The breeding and management of broilers is a comprehensive work. In addition to the following four points, we should also strengthen the management of broiler immunity, beak, feed and feeders, and do a good job in all details in order to improve the efficiency of breeding.

1. insulation at the same time to do a good job of ventilation

The temperature in autumn and winter gradually decreases, and the temperature required in the chicken coop is quite different from the outside temperature. It is necessary to maintain the temperature in the coop and to do a good job of ventilation. At the same time of ventilation, be careful not to let the temperature rise and fall, and strictly prevent diseases caused by stress reaction caused by excessive temperature difference. Vents should be more than 1.5 meters above the chicken's back. When the temperature drops sharply and the cold prevention and heat preservation work cannot keep up, it is often easy for broilers to be exposed to wind-cold, and respiratory diseases characterized by symptoms such as coughing, sneezing, and dyspnea occur.

Therefore, chicken coops should be repaired to prevent thieves and through-hall winds from invading chickens.

Broiler flocks raised on flat ground should be thickened with bedding and use bedding to increase indoor temperature. Change the padding frequently and open the window for ventilation at noon. At the same time, attention should be paid to the changes of chickens and the temperature should be adjusted in time. If the chickens gather together, chatter, shrink their heads, etc., it means that the temperature is too low and the temperature in the house should be increased. In case of open mouth panting and frequent drinking of water, the temperature in the house should be reduced if the temperature is too high.

2. guard against ammonia accumulation and do a good job of cleaning and disinfection

Feces and wet litter excreted by chickens cannot be removed in time, and ammonia accumulates in the chicken house, and the concentration increases, which can easily lead to ammonia poisoning or other diseases in broilers. The accumulation of ammonia in the house, the relative lack of oxygen, coupled with the cold weather, the metabolic rate of chickens increased, for fast-growing broilers, easy to cause ascites syndrome. In order to prevent the adverse effects of ammonia on broilers, it is recommended that chicken farms (households) do the following work: the bedding laid should have a certain thickness, generally more than 5cm; Try to reduce sprinkling water to prevent water leakage from the water tank and wet the bedding. If the humidity is too high, remove the excrement and wet bedding in the house in time, and do a good job of disinfection (water seal evaporates slowly in autumn and winter, liquid spray is not recommended). In addition, ammonia absorption deodorant can be used to reduce the ammonia concentration in the chicken house, and ferrous sulfate, superphosphoric acid, copper sulfate, hydrated lime and the like are commonly used.

3. strengthen feeding management

1, scientific management of new young. Before entering the chicks, the chicks are strictly washed, disinfected and fumigated. Wash utensils, clothes, and houses thoroughly. After broilers enter the house, they drink water first and then eat, and transport them over long distances to replenish the lost water in time. For chickens who are unwilling to move, artificial bombardment and forced feeding measures should be adopted, but attention should be paid to light movements and try to avoid squeezing to death. The illumination time should be shortened, not extended, and the position, time and intensity of the light source should not be changed at will.

2. The ground is dry and not anti-tide. It is best to hit the ground with triple soil, and the ground is breathable and dry without anti-tide. In addition, to control drinking water, drinking water is generally 2 to 3 times the amount of material consumption, but too much water will aggravate the wet bedding. Do not store water in the house to prevent the pad from absorbing water, and prevent water from running when using water pipes.

3. Select the cushion to keep it soft. Use fresh, dry, soft, non-moldy, absorbent bedding. Use it skillfully when using it. It is better to lay the bedding at one time, not to add it sporadically, but to turn it frequently to make it not hard, not to catch felt, not to harden, and to keep it soft.

4, feed nutrition skillful collocation. Due to the low temperature in autumn and winter, the heat consumption of broilers is large. When preparing diets, the standard of metabolic energy in the feed can be appropriately increased, and the proportion of protein in the feed can be appropriately reduced. At the same time, special attention should be paid to the content of vitamins in the diet to meet its needs. Feed should be mixed and fed now to prevent freezing. When conditions permit, hot feed can be fed and warm water can be drunk. The raw grain of the prepared feed must be free of mildew and impurities to prevent respiratory diseases. No excessive salt is used in the diet to prevent drinking too much water, resulting in high water content or diarrhea in chicken manure. In addition. The fat content in the feed should not be too high, otherwise it will make the feces sticky and easy to harpen on the bedding. Dietary protein to add the right amount, too much is not easy to digest, such as feeding bean cake, easy to diarrhea, wet bedding is harmful.

4. to prevent the spread of disease

When the constitution of broilers is weak and the resistance is decreased, the occurrence of some diseases can also be complicated by respiratory diseases. Therefore, while improving the body's resistance, it is necessary to do a good job in the prevention and treatment of related diseases. Vaccines should be strictly in accordance with the immunization procedures for preventive injections, usually often use some drugs to prevent diseases. Disinfect the chicken coop regularly. During the feeding period, it is advisable to use efficient and non-toxic disinfectants for disinfection, and regularly take chickens for disinfection. After the occurrence of respiratory diseases in broilers, they should find a veterinarian in time for diagnosis and prescribe the right medicine. Symptomatic treatment can be appropriate application of some antiasthmatic, cough drugs, can reduce the number of deaths due to breathing difficulties.
