Feeding and Management Techniques of Wuji Chicken in Different Periods
First, the rearing and management of broiler chickens: After the chicks grow to 60 days old, they can enter the stage of rearing. As a species of black-breeding fowl or laying-hens, raising to the hen's approach to egg production (approximately 130-180 days of age), restrictions should be imposed on rearing and timely production. Witches (drugs for domestic use) that are used for medicinal purposes or broilers (exports) for meat use are required to shorten the feeding period, increase the live-weight rate, reduce the consumption of materials, and increase the survival rate and the passing rate of commodities. The standards for Wuji chickens used for medicine are important, and the vitality is 900 grams. The live weight of hens is the export standard, and the rooster is 1000 grams as the standard. (1) Nutritional requirements: Starting from 18 weeks of age, due to weight gain and imminent egg production, necessary nutrients must be stored in the chicken body. The nutrition level of the raising should be appropriately raised, and the nutrition level should be intermediate between the large breed and the laying hens' feed, and the protein feed in the ration should be increased to 25%-30%, and the amount of bran should be reduced accordingly. The general feed formulation is as follows: Formulation (%) of barley mixed feed (bred chicken and commercial chicken) for more than 60 days: barley 10, sorghum flour 10, fish meal 10, rice bran cake 7, corn residue 20, bean cake noodles 15, wheat bran 15, Wheat noodles 7.6, shell powder 5, salt 0.4. (2) Temperature: Under normal circumstances, if the day-night temperature is above 18°C, the temperature can be stopped. When there is a strong wind and the temperature is still to be properly given, attention should be paid to observing the condition of the flock at night to reduce the occurrence of unexpected situations. . (3) Density: For broiler chickens aged from 61 to 90 days, the density of chickens per square meter of indoor ground is 8-10, and that of chickens from 91-140 days of age is 5-6. The density of chickens should not be too large, otherwise it will affect the normal growth and development of chickens. Second, the management of medicinal broiler chickens (1) feeding: broiler chicken growth period from birth to 5 weeks of age, the diet should contain high protein, at the same time to add enough vitamins and trace elements to promote the chicks Growth and development. The fattening period is from 5-8 weeks of age, which is the period of long meat and fat storage. When the diet is combined, the feed containing higher carbohydrates is required, and the crude protein may be slightly lower than the previous period. The ratio of protein and energy feed is appropriate. . Most of the feeding methods use a combination of dry powder and wet powder, and the dry powder must be kept constant. The chicks are allowed to feed day and night, and each morning and afternoon feeds 1 wet material, which can increase the appetite and increase the feed intake. Accelerate the growth and weight gain of broilers. All day feeding is due to mandatory feeding management and is only applicable to medicinal purposes. (2) Management: Requires the chicken house to be cool in winter and cool in summer. The room temperature is appropriate at 16°C to 20°C. Generally, the temperature is slightly higher in the first 2 weeks. In the later period, there is a certain amount of fat under the skin, and the temperature is high. It will increase the mortality rate. With the increase of age and weight, the house should maintain fresh air, drinking water should be clean and sanitary, and water should be kept every day. Its requirements and response to living conditions are not the same, and mothers and chicks have a strong ability to deposit fat, which results in slow weight gain and poor feed efficiency. Male chicks can use proteins and lysine in them to make good use of them, thus increasing weight and feed rate.
