At present, greenhouses raise chickens because they are low in cost and are welcomed by many farmers. However, experts reminded the majority of chicken farmers in the province that chickens in greenhouses affect the growth and development of chickens, and are prone to disease and disease transmission. Drug residues are high and should not be promoted. First, the cost of raising chickens in greenhouses is low. The reporter recently saw an interview with Xiaomiao Town, Feixi County, the largest breeding town in the province. The villager of Xiaomiao Village, Xiaomiao Town, and Yao Jiagui, a peasant woman, have built four plastic chicken sheds. The plastic sheds are mainly covered with bamboo. The film, a plastic film on the roof, was covered with straw to regulate the temperature in the shed. Then the wire was pulled and the facilities in the shed were simple. She told reporters that as long as more than 2,000 yuan a plastic greenhouse can only be used for 3 years. In the village of Samsung Chicken in the village of Wudun, Xiaomiao Town, the reporter saw two standardized chicken houses built by Xu Yingming, a farmer. He told the reporter that a broiler house invested about 40,000 yuan, and a group of chickens could raise 6000-7000 chickens. The house is a brick-concrete structure with a double membrane on top, a straw in the middle, and a steel frame inside. For larger shed chickens, the broiler chickens are easy to manage, easy to sterilize, save feed, the chicken grows fast, and the feed-to-meat ratio is high, but the one-time investment is larger. Xiao Congzhen mayor Hong Cong Gui revealed that Xiaomiao Town has slaughtered 30 million chickens annually, accounting for 30% of the chicken production in Hefei City. About 50 chicken farmers in the town are raising chickens in chicken-raising districts, and there are about 1000-2000 households in greenhouses. The main reason why greenhouse chickens are welcomed by local farmers is that the main reason is that they have invested less money. Second, there are many drawbacks in raising chickens in greenhouses. Dr. Jiang Runshen of the Animal Science and Technology College of Anhui Agricultural University told the reporter that there are more drawbacks in raising chickens in greenhouses. One is the high density of the greenhouses and the slow growth of chickens. The number of chickens held in greenhouses is controlled at about 5,000 broilers. If it is between 8,000 and 10,000, the density is higher. In the greenhouse feeding area, the spacing, size and ventilation of the greenhouse should be reasonably distributed. The spacing between the greenhouses should be 3-5 times the span. According to reporters in Xiaomiao Town, most of the greenhouses are a shed and a shed, and some are connected; the second is poor health and epidemic prevention, and the incidence rate is high. Greenhouse chickens are placed on the ground to raise, eat and drink Lazard all in that piece, and it is easy to breed bacteria. If a chicken is sick, it will have to use drugs. This will not only increase the cost, but also cause chickens with large drug residues and affect sales. In particular, some chicken farmers do not have the concept of health and epidemic prevention. Farmers smash each other, look at each other chickens, do not sterilize, do not change clothes, and the incidence of a chicken causes several chickens to develop at the same time. Third, chicken house chickens are safe and safe. Zhang Miao, director of Agricultural Machinery Station of Xiaomiao Town, said that according to the calculation of 6,000 chickens, the cost of breeding chicken houses is more than 2,000 yuan more than greenhouse cultivation. The chicken house is cultured and ventilated quickly. The concentration of ammonia is low and the seal is good. The virus cannot go in and it is not easy to infect the disease. Poultry greenhouses have poor environment, high ammonia concentration, and chickens are susceptible to diseases. Warming in chicken house breeding sites is a local warming, and people work very safely. In greenhouses, coal stoves are heated in greenhouses and are prone to gas poisoning. There have been poisoning deaths in chicken sheds in towns. There is a drainage ditch in the broiler house, which has a strong ability to resist wind and rain; the rainwater in the greenhouse will flow into the shed, causing chickens to crush and die. The chickens in the chicken house are brightly colored, strong in resistance, small in dosage, good in quality, and easy to sell; chickens grown in greenhouses are disordered in color, prone to illness, and have high dosage and poor quality. Fourth, greenhouses should pay attention to raising chickens. Dr. Jiang Runshen believes that if chickens in greenhouses are well-made, they can be used. Gaps and sheds cannot blindly pursue low cost. With limited funds, chicken farmers must pay attention to reasonable planning and scientific breeding. First, the layout must be reasonable. The number of chickens in a greenhouse should be controlled between 5,000 and 8,000. The shed spacing should be more than 3 times the span and the length should not exceed 70 meters. The second is to raise the level of culture. Can not only feed corn and other single feed, with the feeding, nutrition should be comprehensive; the third is to scientifically prevent disease. The chicken-raising households must have a concept of epidemic prevention, should conduct daily disinfection, and must have certain isolation measures. The surrounding environment and open space of the chicken house should be limed and sprayed inside and outside the greenhouse. In the first two weeks after the chicken is on the market, it is necessary to stop feeding antibiotics and other drugs and control the drug residue within a certain range. Fourth, the greenhouse equipment should be improved. The ground floor of the greenhouse should be made of concrete floor, and each batch of chickens should be cleaned after slaughter. Bricks are used to construct pillars. Asbestos roof tiles and grass curtains are used as roof materials. The environment of chicken coops is better and the survival rate of chickens is higher. Fifth, advocate the regulation of chicken farming. Zhang Baozhan believes that in the future to gradually promote the standardization of chickens, chicken breeding community promotion, you can advocate chicken farmers 2-3 households to build a standardized chicken-raising area, and gradually regulate the production of chickens, improve the breeding technology, enhance Market Competitiveness. Dr. Jiang Runshen told reporters that bird flu reminds us to standardize chicken breeding. In the future, poultry breeding households that are not qualified for breeding should be banned from rearing. An access system must be established, and the breeding environment, construction sites, and chicken-raising equipment should be standardized; Large-scale rearing, mainly in captivity, opened a playground around the chicken house, pulled the net around the house, and stocked it in the house. Feeding technology, in the feeding process to strengthen the control of feed nutrition, to control the environment of the chicken house, such as temperature (summer cooling, winter insulation, chicken heating, etc.), humidity, light, etc., can not blindly raise, Otherwise, the slaughter rate is low, the profit is low, and the breeding effect is poor.
