The male rabbits should be pure breeds, be rich and well-groomed, be well developed, have a strong physique, have a strong sexual desire, and have excellent semen quality in order to complete the mating task and breed good quality offspring. As the saying goes: "The female rabbit is good and has a good nest; the male rabbit is good, it's a good slope." The quality of male rabbits plays a crucial role in offspring and rabbit populations. Therefore, male rabbits must be scientifically reared and managed.
First, breeding male rabbits should pay attention to the full price of feed
The quality of male rabbit semen depends on the nutrients in the feed, especially the protein, vitamins, and minerals in the feed, so nutrition must be guaranteed.
1. Protein: When the protein in the diet is sufficient, the male rabbit has a strong sexual desire, good semen quality, strong breeding ability, and female farrowing. Under normal circumstances, the protein content of male rabbit feed should be maintained at 16% -18%.
2. Minerals: Calcium and phosphorus are essential nutrients for male rabbits to form semen. When the content of calcium in the feed was insufficient, the male rabbit showed weakness in the limbs, decreased ability to mate, poor sperm development, reduced sperm motility, and decreased number of litters after mating. Phosphorus is the main component of nuclear proteins and is also a mineral essential for sperm production. Zinc plays an important role in sperm maturation. When zinc deficiency occurs, sperm motility decreases, and deformed sperm increase. Selenium can affect the development of reproductive organs and sperm production in male rabbits. The lack of selenium reduces the weight of the testes and epididymis, and decreases sperm motility and energy. Therefore, male rabbits should ensure that mineral content is sufficient in the diet of rabbits, and can satisfy the rabbit's need for minerals by adding trace element additives to the diet.
3. Vitamins: Insufficient vitamins in the diet can affect the normal physiological metabolism of male rabbits, resulting in loss of appetite, stagnation of growth, and a decrease in the number of normal spermatozoa and the ability to fertilize. Therefore, to provide male rabbits with rich vitamin content of green feed, carrots, leaves, etc., or to add complex vitamins in the feed, can significantly increase breeding male rabbit performance.
Second, adjust the male rabbit diet according to the season
Spring and autumn seasons are the peak season for breeding male rabbits, and they are also the moulting season. In this period, male rabbits need a large amount of protein to meet their own and breeding needs, so the protein content in the diet should be increased. In winter, the weather is cold and the energy consumption is fast. The proportion of energy feed in the diet should be increased, and the adequate supply of vitamins must be ensured to lay a good foundation for spring breeding.
Three kinds of male rabbits should be raised in a single cage
Male rabbits live in poor communities and are good at biting. Therefore, they must be raised in a single cage and the cages should be large enough to provide male rabbits with large enough space for breeding and sports. At the same time, male rabbits must exercise to increase their ability to breed and semen quality.
IV. Controlling the Number of Breeding of Male Rabbits
The frequency of mating is generally 2 times per day, and the reserved species cannot be used prematurely to avoid affecting growth and development and causing premature aging. Adult male rabbits should rest for 1 day after two days of mating, and do not use too many times, otherwise it will affect male rabbit semen quality and service life. In order to avoid heavy mating of male rabbits, each male rabbit can be fixed 8-10 female rabbits, and the male rabbits must also regularly check the genitals. If any inflammation or other disease is found, the breeding should be stopped immediately and the treatment should be promptly given.
