Key technologies for rabbit breeding
1. Breeding Breeding Rabbits are divided into American lines, German lines, and legal lines by pedigree. Due to different cultivation conditions and directions, the three strains have their own characteristics. The U.S. strains have high adaptability, disease resistance, and fertility, but their size is smaller and the individual differences are larger. The Ashkenazi rabbits are large in size and grow fast, but have poor adaptability and fertility; The advantages of the German system, but the introduction of a short time, the introduction of a small number, still need to strengthen the breeding and adaptive exercise. For breeders, there is no need to insist on which strain is good, as long as the production of good skin is a good rabbit. Must emphasize the usual breeding, good breeds are not necessarily all good offspring, only good selection, excellent selection, perseverance, after five consecutive generations will develop an outstanding group. During the breeding period, attention should be paid to the coat density, coat level, coat length, early growth rate, feed reward, disease resistance, litter size, lactation force, and maternality. Second, pay attention to nutrition Rabbits expensive in the fur, fur growth requires more nutrition, protein requirements than other rabbits, especially sulfur amino acids (methionine and cystine) higher. With the nutrition standards, it is also necessary to carry out a reasonable mix of feed varieties, nutritional characteristics and feed prices in different regions. 1. Pregnancy female rabbit formula: loquat leaf powder 7%, corn stalk 5%, soybean straw 23%, corn 39.8%, soybean meal 12%, soybean 5%, bone meal 1.5%, fish meal 2%, shell powder 0.5%, flax cake 3%, salt 0.5%, rabbit music 0.5%, methionine 0.1%, lysine 0.1%. Formula for lactating female rabbits: 9% of loquat leaf powder, 25% of soybean straw, 36.5% of corn, 12% of soybean meal, 10% of fried soybean, 1.5% of bone meal, 2% of fish meal, 3% of shell powder, 0.5% of salt, 0.5% of rabbit music . 2.Fattening rabbit feed formulation: 6.5% of eucalyptus leaf powder, 23% of soybean straw, 38% of corn, 12.74% of soybean meal, 5% of wheat bran, 7% of soybean, 1.3% of bone meal, 1.5% of fish meal, 0.16% of shell powder, flax cake 3%, salt 0.5%, rabbit music and ball net each 0.5%, methionine 0.15%, lysine 0.15%. 3. Feeding formula for puppies: 10% of foliar meal, 10% of soybean straw, 38% of corn, 17% of soybean meal, 6.9% of wheat bran, 12% of soybean, 1.2% of bone meal, 3% of fish meal, 0.5% of salt, rabbit 1%, methionine 0.2%, lysine 0.2%. 4. Empty female rabbit formula: 8% foliar powder, corn 5%, soybean straw 23%, corn 33%, soybean meal 8%, wheat bran 11%, soybean 5%, bone meal 1%, flax cake 2.5%, cotton Ren cake 2.5%, salt 0.5%, rabbit music 0.5%. Third, weight control Rabbit weight is not the bigger the better. Rabbits weighing more than 5 kilograms have absolutely no high reproduction rate. According to experience, the average body weight can reach 3.5-4 kg. For rabbits with reserve potential for growth, it is necessary to adopt a strategy of promoting the control of the rabbit beforehand, and it is impossible to grow the body in an unlimited amount in the later period. Generally, the method of restricting feeding is adopted. That is, when a certain weight is reached, the amount of feeding is controlled to be about 85% per day. For breeding rabbits, it is necessary to control the lyrical condition and prevent over-fertilization. Fourth, the commercial rabbit fattening According to research, early postnatal rabbit hair follicle differentiation, if the nutrition is satisfied, the hair density can be greatly improved. After 3 months of age, the hair follicles are differentiated slowly. After 5 months of age, the differentiation of the hair follicles is almost complete. At this time, providing higher nutrition will not help. Therefore, early culture of commercial rabbits is crucial. In terms of management, the following points should be noted: First, strengthen environmental control. The temperature should be kept between 15 and 25 °C. The temperature at the late stage of fattening can be appropriately reduced to improve the quality of the fur; the humidity is controlled at about 60%; 10 to 14 fattening rabbits are reared per square meter of cage area; there is a certain amount of light, but No need for strong light; strengthen ventilation, keep the air fresh in the rabbit house; keep cages clean, sanitary, and healthy. Second, improve feeding techniques. The best form of feed is pelleted feed, and free-feeding can increase the rate of weight gain. Unconditional wet mix can be taken with powder, to feed in the hands into a group, the fingers are sewn with water, but not dripping, open the cracks can be, take regular feeding, less feed Tim Tim; farmers raise rabbits, in the green feed In the season of supply, it may be possible to adopt green feed as the main ingredient during the day and supplement the fine feed at night so as to save feed costs. Third, free drinking water and providing sufficient clean drinking water.
