The breeding male rabbit plays a crucial role in the rabbit population, and its quality will affect the quality of the entire rabbit population. As the saying goes, "A good mother rabbit makes a good nest; a good male rabbit makes a good slope. The task of breeding male rabbits is to breed and breed offspring. The quality of male rabbits directly affects the conception rate and litter size of female rabbits, and greatly affects the vitality and quality of their offspring. Only good and excellent male rabbits can obtain a large number of good offspring. Therefore, when the genes of the male rabbits are determined, the breeding and management of the male rabbits will play a decisive role. Below, the manufacturer of Mengyin Changmao Rabbit will explain to you:
1. Breeding management during non breeding period
Although there is no obvious season for the breeding and reproduction of meat rabbits, there are light and peak seasons, especially in the northern regions where breeding and reproduction are mostly concentrated in spring and autumn, and less in summer and winter.
During the non breeding period, male rabbits are recovering their physical strength and energy, and their physiological burden is not heavy. Therefore, they only need to be fed with medium nutrient levels of feed. However, attention should also be paid to the comprehensiveness and balance of nutrition in feeding, and various nutrients in the diet should not be lacking, especially protein, vitamins, and minerals.
Can provide medium level feed, mainly green feed, supplemented by mixed concentrate. Moderate body fat is recommended, and should not be too fat or too thin. Practice has shown that the daily feed amount for non breeding period male rabbits is 800-1000 grams per animal. In addition, add a small amount of concentrate and feed at a daily rate of 30-50 grams per animal. In winter, each animal can be fed 200-500 grams of coarse feed and 300-500 grams of carrots per day.
Management requires single cage or small group feeding, with dry, ventilated, and transparent cages. Exercise should be sufficient, and farmers can set up a sports field in the courtyard, playing once a day for 1-2 hours each time. Factorized rabbit farms can increase the size of the rabbit cage to facilitate male rabbits' movement inside the cage.
2. Breeding management during the breeding period
The nutritional level of male rabbits directly affects their mating and semen quality. Therefore, attention should be paid to the full valence of nutrition in breeding, especially the need for protein, vitamins, and minerals. At the same time, it requires small size, good palatability, easy digestion and absorption, and long-term stable nutrition.
In the nutritional composition of the diet, the first step is to ensure the protein requirement by adding an appropriate amount of protein rich feed such as soybean cakes, soybean dregs, and alfalfa. Long term feeding of low protein diets can cause a decrease in semen quality. For male rabbits with poor semen quality, 15 to 20 soaked and cooked soybeans, silkworm pupae, and leguminous forage can be supplemented daily to improve the semen quality and mating conception rate of male rabbits.
Mineral elements also have a significant impact on the semen quality of male rabbits, especially calcium. If calcium is lacking in the diet, it can cause incomplete sperm development, decreased vitality, and limb weakness in male rabbits. There is generally no phosphorus deficiency in the diet, but the appropriate calcium to phosphorus ratio is also very important for the reproductive ability of male rabbits, which should be generally 1.5:1 to 2:1.
Vitamins also have a certain impact on the breeding ability of male rabbits. Therefore, an appropriate amount of trace elements should be added to the diet, as well as vitamin rich feed such as carrots, barley malt, and grass.
Although green feed contains abundant vitamins and is generally not deficient, it is easy to cause symptoms of vitamin deficiency when there is less green feed in winter or when pellet feed is fed year-round. When male rabbits lack vitamin A, it can cause degeneration of the epithelial tissue of the testicular fine tubules and an increase in the number of abnormal sperm, which can be corrected with green feed or various vitamins.
3. Feeding management before breeding
Starting from the 20th day, adjust the diet formula to increase protein levels to 14% -15%. During the peak season of breeding, animal feed should be appropriately added or supplemented, such as fish meal, silkworm pupa, eggs (1/4-1/2), and bone meal of 5 grams per day. When the frequency of breeding increases, such as reaching 2 times per day, the diet should be increased by 25%. In terms of nutritional supply, attention should also be paid to long-term and sustainability, and do not easily change feed. The feeding method can be limited feeding to control the body weight at medium fat level.
4. Breeding male rabbits must be raised in a single cage
The cage of male rabbits should be kept at a certain distance from the cage of female rabbits to reduce heterosexual stimulation and avoid decreased sexual desire during breeding. The arrangement of mating intensity should be reasonable, with a ratio of male and female rabbits, and a suitable artificial assisted mating ratio of around 1:10; If artificial insemination is used, it can be increased to 1:100-150. Young male rabbits should not be bred more than once a day; Adult male rabbits can mate twice a day, and should be arranged once in the morning and afternoon. They should mate for two consecutive days and rest for one day.
Provide a clean, hygienic, dry, cool, and quiet environment. The bottom plate of the cage should be flat, straight, and straight, with moderate gaps and no nail heads or burrs to prevent foot dermatitis or damage to the scrotum and testicles. Achieve four mismatches: mismatches within half an hour before and after feeding; Breeding male rabbits do not mate during hair changing; When the health status of male rabbits is poor, they are not suitable; The weather is hot and there are no cooling facilities.
In short, the breeding requirements for male rabbits are good development, strong physique, neither fat nor thin, and their body fat should reach the level of seed fat; Strong sexual desire and strong mating ability; The semen quality is good, and the conception rate is high compared to the mating mother rabbit. The breeding and management of male rabbits should be divided into breeding period and non breeding period. For more related content, come to our website http://www.myxinhua.com consulting service
