On the age of rabbit breeding
The age of breeding in rabbits is different by species size, genetic difference, and initial age. However, there are other problems that cannot be ignored, such as whether the feed is full price, whether the management is extensive, and whether the growth temperature is suitable. Huinong School has collected some knowledge about rabbit breeding. Let's talk about the age of the medium-sized meat rabbit and the rabbit.
The age of breeding in rabbits depends on the sexual maturity of the rabbit. The intensive rabbits in foreign countries use full-price feed, good management, and the age of breeding is as early as 4 months (please don't try). Good domestic feeding conditions are 5-6 months old, and the minimum weight standard is 3-3.5 kg or more. Through the practice observation of breeding rabbits, rabbits still maintain a relatively fast growth rate after initial matching and calving, until the adult body weight can reach the standard. However, some rabbit-raised homemade feeds can not reach the full price, and the rabbit house is greatly affected by the temperature difference of the four seasons. In particular, some meat rabbits are managed extensively, even using straw, vegetable leaves and weeds to feed rabbits. In this case, it is unscientific to use 5-6 months old breeding. Because rabbits do not meet the standard weight, weak calves, and less lactation, it seriously affects the survival and growth of the rabbits. Even if the initial weight is up to standard, but due to the inability to grow food, pregnancy, lactation, resulting in growth stagnation, the rabbit has become an old rabbit that will never grow up, the variety is seriously degraded. In this case, some farmers are facing the good breed rabbits they have purchased and are blaming the research and supply departments.
In view of the above reasons, the breeding age of rabbits should be combined with body weight and growth rate, and the three are equally important, which can minimize the degradation of rabbits. The feed nutrition level is low, and the farms and households that are behind the rear should be appropriately relaxed. The weight of the initial weight is increased to 60% of the adult weight, and the age of breeding can be postponed to 8-10 months. Especially in the cold winter, this should be the case, so don't be scornful, otherwise the loss will not be small.
Raising rabbits is also a matter of time, in the growth of rabbits, by saving feed, promoting growth, more complex, faster, and increasing survival rate is a necessary means to increase profits and improve efficiency, and must rely on the planned production of rabbits to implement and complete Should try to avoid the adverse effects of the season.
Spring and autumn produce two births, one winter, and the annual five-child plan is the consensus of most domestic rabbit breeders. In spring, all things recover, the climate is mild, the forage is rich, and the rabbit grows the fastest. It is the golden season for rabbits and rabbits. In order to make good use of the favorable characteristics of spring, it is necessary to do the breeding and childbirth work, preferably at the end of winter. Once the spring is warm, the green grass turns green. The rabbit can develop and grow rapidly, and the rabbit enters the next breeding season. By the end of the summer, the three-child production plan can be completed.
As for the summer calves, most people in the rabbit industry are opposed, but I think the opposite. In the midsummer, the appetite of the rabbits is diminished, the body is not good, but the body is not good, but as long as it is shaded, sprinkled, and ventilated, it is good to cool down. Feeding the green fodder at noon, and drinking enough water all day, breeding is not a big problem, especially in the north, promoting summer breeding. Raising the rabbit industry is extremely beneficial. For example, breeding in July and aborting in August, the growth period in September is the same as the autumn, the forage is rich, the growth rate is fast, the feed cost is low, and the benefits are obvious. However, in the summer, the speed of reproduction should be slowed down in summer. Due to the high temperature, the newly born rabbits sometimes have a suspended animation. The production box should be taken out in a cool, ventilated place to help the rabbit recover.
At the beginning of winter and the end of spring, it is not a favorable time for rabbits to breed. The rabbits they produce will face long winter and summer. No matter whether it is experiencing high temperature and heat, or the young rabbits that are frozen in the cold, it will inevitably affect their growth, gain weight, increase feed consumption, and the benefits will be relatively poor. On the occasion of the mid-summer winter, all the rabbits that have reached the selling standard will be sold, otherwise the disadvantages will be less.
Insulation conditions are poor, and the households with insufficient heating should compress the rabbits at the beginning of winter to avoid the adverse effects of low feed rate and feed intake due to low cold-to-low ratio of hay. The end of the breeding and refueling, and lay a firm foundation.
At the beginning of winter, it is also a good time to eliminate the aging and poor rabbits, and to integrate the rabbits, and also reduce the occurrence of the rabbits. The author updates 50% of the rabbits at the beginning of each winter (equivalent to two years and one species). Since the young rabbits are not yet mature, the weight is relatively small, which saves a lot of feed, and once it reaches the breeding season, it can be fully embraced. Fully equipped.
Rex rabbit breeding should take advantage of the relationship between fur and season, and advocate the summer to not relax the breeding work, while the sale period of commercial rabbits is to avoid the summer, so that it can do more with less, and achieve the purpose of increasing efficiency.
I have learned the age of the first-in-class meat rabbit and the rabbit. Did the farmers learn something? Huinong School will continue to bring more relevant agricultural technology to everyone.
