Scientific measures for ewe mating
2023-03-05 07:07:30
Autumn is the golden season for estrus mating of ewes. The proper mating of ewes of the right age is the most effective measure to increase the quaternary birth rate and multi-crop rate. Selection of breeding sheep
The use of a litter of male and female rams as a species, to maintain the characteristics of sheep breeds. With reminder
The ewes of the appropriate age should be fed for a short period of time one month prior to their mating, and 0.2 to 0.25 kg of supplemental concentrate per day. The ewes of the age-matched ewes only have good estrus, normal estrus, and increased number of ovulations, thereby increasing the quasi-fetal rate and omnipotence of the ewes. Raise the age of ewe
The percentage of sheep in the flock is generally higher than that of the second-row ewes. Therefore, it is necessary to control the proportion of high-yielding ewes in the flock. 4 to 6-year-old ewes account for 50 of the total number of sheep. % ~ 60% is appropriate.
Grab a catch
The proper timing of sheep mating is a good time for grabbing autumn fleas. Grasping autumn fleas will increase the number of ovulation of ewes significantly, the ram will have a strong libido, the quality of semen will be better, and the quasi-fetal rate and multiple birth rate will increase. Empathy, ovulation and more.
Timely breeding
Each estrus duration is 24 to 40 hours, and the ovulation time is 30 to 34 hours after estrus starts. Therefore, timely breeding time should be 12 to 25 hours after estrus. Older ewes have short estrus duration and should be bred early after estrus. Young ewes have a longer estrus time, and breeding time should be later.
Scientific breeding
Due to the different age of ewes, the timing of breeding is not the same. Older ewes have short estrus duration and should be bred early after estrus. Young ewes have a longer estrus time, and breeding time should be slightly later. Middle-aged ewes are moderate in estrus, and breeding time is between old and young sheep. . In addition, 13 to 14 days after the estrus estrus, in the hen's hind leg subcutaneous injection of 8-10 milliliters of pregnancy horse serum, every other day or every day after injection, after 3 to 4 days, timely estrus breeding, can greatly increase the rate of childbirth and Multi-rabbit rate. Implementing compounding
Usually within one estrus period, fertilization can be performed once the animals are bred. However, in order to increase the rate of quasi-childbirth and the number of lambs, it is possible to breed two times in the middle and late stages of estrus, or at different times during one estrus period. Three rams each have one time. If it is artificial insemination, the effect is better, and the rate of quasi-fetal and the rate of multiple lambs can be significantly increased.

Introduction:
The body produces carnitine in the liver and kidneys and stores it in the skeletal muscles, heart, brain, and other tissues. But its production may not meet the needs under certain conditions such as increased energy demands and therefore it is considered a onditionally essential nutriention. There are two forms (isomers) of carnitine, viz. L-carnitine and D-carnitine, and only the L-isomer is biologically active.
