The temperature rises and forage grass enriches the breeding techniques of hare in spring.

With the rise of temperature in spring, the fertilization rate of hare is high, and it is the peak season of weeds and forage production, so mastering the breeding of hare in spring can improve the economic benefit of hare breeding.

Hare

1. Select the breeding rabbit: it is better to breed the young and middle-aged male rabbit with strong physique, good development, stable gene and exuberant libido. Excellent female rabbits with good genital development, normal estrus, high litter yield and high lactation were selected.

2. Mating: when the body weight of breeding rabbits reaches more than 70% of the annual body weight, the first mating can be carried out. The female rabbit has estrus every 15 days and lasts for 2-3 days. The mating time can be determined according to the pubic color of the female rabbit, that is, "early pink, late black and purple, and red mating time". Mating time should be at night, so as to facilitate the care of babies during the day. A female rabbit can mate with a male rabbit twice (usually at an interval of 4 hours) or with two male rabbits successively (usually at an interval of 2 hours). After mating, lift the buttocks of the female rabbits and tap them a few times to make the muscles tense, prevent semen reflux and improve the fertilization rate. After mating for a week, the female hare is put into the cage of the male wild rabbit. If the female hare refuses to climb the hips of the male wild rabbit, it indicates conception, otherwise it has to be remated.

3. Feeding and management of female rabbits during pregnancy and lactation: in the middle and later stages of pregnancy, female rabbits should be carefully managed. In order to prevent abortion, attention should be paid to dietary nutrition level and feed hygiene, no mildew feed, no sudden change of diet, and no random capture or shock. Five days after giving birth, the daily feed should be increased by 1 to 1.5 times, and more fresh green and succulent feed (such as dandelion, bitter lettuce, lettuce, leaf, etc.), bone meal, fish meal, bean cake, minerals and a small amount of salt should be fed to increase the milk yield of female wild rabbits.

4. Feeding and management of baby rabbits: it is best to adopt artificial care for the newborn rabbits, dry them with clean gross coins and eliminate the dirt of their blood hairs. After the mother rabbits give birth to their cell coats, feed them some warm water, preferably 5% brown sugar water or 0.9% salt water. Then move the rabbits into the incubator covered with soft grass and breast-feed them once, and then put the mother rabbits into the incubator every 24 hours. As the temperature is low in spring, the young rabbits should keep warm and control the temperature of the rabbit house: 1-5 days old, the most suitable temperature is 30-32 ℃, 5-10 days old is 25-30 ℃, and then keep at 15-25 ℃. The young rabbits began to be fed 16-17 days after birth, and could be fed with green and tender grass, and gradually fed with full-price compound feed with high nutritional value, good palatability and easy digestibility. After 35-40 days, they could be weaned.

5. Health and epidemic prevention: it is cloudy, rainy and humid in spring, which is the peak period for the occurrence of various diseases. attention should be paid to moisture prevention and disease prevention in breeding, the health status of rabbits should be checked every day, and rabbit cages should be cleaned, disinfected and sterilized well. The rabbit cage had better be cleaned once a day and disinfected every 7 days. In cloudy and rainy days, the ground can be covered with some quicklime, plant ash and so on for disinfection, sterilization, moisture-proof. Let the hare bask in the sun as much as possible during the day, and artificial light should be used sooner or later to avoid affecting the growth of the hare due to lack of light. In addition, we should observe frequently and find that sick rabbits should be isolated and treated in time, and cages should be strictly disinfected.
