Technical Key Points of Artificial Insemination in Turkey Breeding
In order to solve the problem of difficult mating in large turkeys and to improve the utilization rate of breeding male turkeys and the fertility rate of breeding eggs, the method of artificial insemination should be adopted for mating. During artificial insemination, strong male turkeys of excellent quality must be selected. Each male turkey can simultaneously inseminate

Technical Key Points for Pollution-Free Classical Swine Fever Prevention in Pig Farms
1. Isolation measures Countries and regions that have eliminated classical swine fever mainly adopt measures such as prohibiting the introduction of live pigs, pork and inadequately heated classical swine fever products from countries and regions where classical swine fever exists, in order to prevent the reintroduction of classical swine fever virus. If classical swine fever cases appear, the infected herd shall be destroyed immediately

Technical Measures for Improving the Reproduction Rate in Rex Rabbit Breeding
1 Improving Mating Methods Adopting repeated mating or double mating can significantly increase the conception rate and litter size of does. Repeated mating means that after the first mating, at an interval of 4-6 hours, the same buck is used to mate once more. Double mating means that 1 doe is mated successively with 2 bucks

Detailed Explanation of Key Points in Dairy Cattle Breeding Technology, a Must-Read for Farmers
1. Formulate breeding indicators for the herd. To draw up a breeding plan, the first step is to determine breeding indicators. The ideal reproductive rate should reach 100%, with a calving interval of 12 months, but this is difficult to achieve. Therefore, in actual production, the reproductive rate should not be lower than 85%, and the calving interval should not exceed

Rapid Finishing Breeding Technology for Meat Ducks in Multi-Tier Cages
I. Advantages of Cage Rearing for Meat Ducks: First, it makes full use of the duck house space, increases stocking density and raises output per unit area. Second, mechanized equipment can be used to reduce labor intensity. Third, the diet is nutritionally complete and feed intake is uniform, and the finishing time is shortened to about 60 days,

Key Technical Points for Natural Mating Breeding of White-Feathered Broiler Chickens
(1) Male-to-female ratio The male-to-female ratio refers to the number of hens each rooster is responsible for mating. Taking free-range floor rearing as an example, the male-to-female ratio for fast-growing white-feathered broilers is 1:8-10, for high-quality white-feathered broilers it is 1:9-12, and for layer-type chickens it is 1:10-13. If raised on wire-floor flat rearing, the lower limit should be adopted;

Key technical points for overwintering storage of river crabs: these methods you need to master
River crabs are generally caught and brought to market in a concentrated period from early October to the end of November each year, so the volume is large and the price is low, and farming profits are not high. Overwintering storage of river crabs helps stagger the peak marketing season, raise the market price of river crabs, and thereby achieve the best economic benefits. 1. The pond should
