Turkey breeding technology
Turkey scientific name spit chicken, also known as the seven-sided bird, native to the Americas, is a kind of high-grade wild game rare meat that is imported from abroad. 1, the economic value of breeding turkey: turkey tender and delicious, good taste. Turkey's protein content is 20% higher than other poultry, while fat content is 21% lower, and cholesterol is low. Turkey is mainly herbivorous, with fresh meat, no smell, no odor, no drug residue, pure and delicious taste, suitable for both young and old. It can adapt to high-grade dining tables and meet ordinary families. It is a good product with nourishing nutrition and good food. 2. Benefits of turkey breeding: Turkey has the characteristics of large body growth, high meat production rate, strong fertility, easy management, and high profitability. Turkey grows fast. Under normal circumstances, 140 days of heavy turkey cocks can reach 16 to 20 kilograms, hens can reach 9 to 15 kilograms; medium turkey cocks can reach 13 to 15 kilograms, and hens can reach 8 to 10 kilograms; light turkey cocks Up to 10 to 12 kilograms, and hens up to 5 to 8 kilograms. Turkey has a high rate of meat production. Turkey has developed breast meat and leg meat, accounting for more than 40% of live weight, live slaughter rate of 64%, carcass slaughter rate of more than 85%. Turkey breeds strongly. Artificially hatching each turkey can produce 180 eggs per year. The natural hatching can produce 80 to 100 pieces per year. The rate of insemination can be as high as 90%. Turkeys generally grow to 6-7 months of age and begin to lay eggs. Every time they produce 15 to 25 eggs, they begin to hug their nests. The hatching period is 26-28 days. After the chicks hatch about 10 days, they lay eggs again and produce 15 eggs. When it comes to ~25 pieces, it is hatched again and the production cycle continues. With artificial hatching, hens are not allowed to hug and they can continue to lay eggs. Turkey is easy to manage. Turkey is a wild animal in the Americas. It feeds on plant stalks, tender odor, seeds, and insects. It is resistant to heat, cold, rain, rain, and snow. It adapts to a variety of harsh conditions. With artificial rearing, all crop stalks are crushed into powder and mix well. All of them can be used as turkey feed and can be adapted for grazing and grazing. The 300 to 500 animals per person in the countryside do not affect their job. The turkey was born heavy and big, and the survival rate was high. The newly hatched turkey can weigh 110-130 grams and its survival rate is above 95%. Turkey has a high input-output ratio. The turkey is a herbivore, and the input of fine material is very small. In addition to the normal feeding of grass, every year only needs to invest 20 yuan for water and electricity feed, which can achieve the effect of scientific rearing. The income can be 80 to 100 yuan. 1:4~5. It has the advantages of less investment, multiple outputs and high benefits. 3. Market analysis of turkeys: Turkeys are very popular abroad and have already been scaled for factory farming. Although China has not introduced them for a long time, turkey has a fast growing, big, tender and delicious nutrition, and herbivorous festival. The rapid development of the grain economy has been listed in the “State Spark†development rich project, and the development prospects are very impressive.
