Matters needing attention in ewe breeding
Ewe breeding is an important stage of sheep breeding, so some aspects need to be very particular in order to ensure the litter yield in the later stage. Some details are easily ignored by farmers and lead to a reduction in production. The following editor will introduce to you some details that ewe breeding should pay attention to.
1. Prenatal fattening
Prenatal fattening is a problem that some farmers will not pay attention to. In fact, if we do some statistics, we will find that the relatively fat sheep are higher than the thin ones in terms of the number of cubs, the survival rate and the chance of conception. So prenatal fattening is very important. As long as the ewe has enough nutrition, it is possible to produce more eggs during the mating period. Of course, prenatal fattening when we also need to feed some feed to promote ovulation and so on has reached a complementary effect.
2. Selection of mating time
The mating time is generally divided into two periods: spring and autumn. from the point of view of editors, it is better to mate in spring. First of all, the temperature begins to warm up slowly at this time, the temperature is warmer, the corresponding ewe's egg activity will also become a little higher, mating is easier to succeed. Secondly, after recuperation in winter, the estrus in spring is almost the best time of the year in terms of duration and quality, and the success rate and quality of mating will be relatively high. At this point, farmers can make good statistics to get the results.
3. Selection of mating methods
Not every ewe will accept mating in estrus, so we should have different ways to breed such ewes. Before mating, you can raise rams and ewes together for a period of time, and if possible, let them mate directly. if ewes are unwilling to change rams, artificial insemination or aphrodisiac drugs are recommended to help with breeding. Must not start forced mating, it is easy to hurt ewes, resulting in later difficult breeding.
4. Management of breeding and breeding
The management during the mating period should be different from the usual, and we can no longer be the same as the breeding during the normal period. First of all, the living environment should be changed, and the grass needs to be added to the bottom to avoid making the ewes cold. Secondly, the number of breeding in the same enclosure should be reduced, with 3-4 heads as the best, so that they can have a good growth environment and enter estrus earlier. In terms of feed, some items to promote estrus should be added appropriately to ensure that the estrus can be relatively consistent.
These are some of the problems that ewes need to pay attention to during mating, when ewes and rams are easy to be grumpy, for their safety, we should increase the monitoring time. The rams and ewes should be separated immediately after breeding, so as not to quarrel with each other and get hurt.
