In autumn, the aquatic plants are rich, the grass is mature, the seeds are full, the nutrition is rich, and the weather has become cool and pleasant. It is a good season for sheep to do a good job in autumn fat and ewe breeding. We should do a good job in management. Autumn shepherd grazing, autumn fat 1. Choose pasture., Pasture should be selected for high-lying, winter and can not use the hillside grassland or hiragawa mountain. When the weather turns cool in late autumn, try to graze in a big ditch with good grass so that sheep can walk less and eat more grass. 2. Grazing time. Autumn noon sunshine is strong, the temperature is high, the sheep is easy to heat stroke, should avoid grazing at noon. Early grazing, late grazing, and provide sufficient drinking water for the sheep, so that the sheep can eat and drink enough,
In autumn, the aquatic plants are abundant, the grass is ripe, the seeds are full, the nutrition is rich, and the weather becomes cool and pleasant. It is a good season for sheep to grasp autumn fat and ewe mating.
Section, should effectively grasp the management work.
In autumn, shepherds grasp grazing and keep autumn fat.
1. Choose pasture.
The pasture should choose high-lying, winter and can not use the hillside grassland or hiragawa mountain. When the weather turns cool in late autumn, try to graze in a big ditch with good grass so that sheep can walk less and eat more grass.
2. Grazing time.
Autumn noon sunshine is strong, the temperature is high, the sheep is easy to heat stroke, should avoid grazing at noon. Early grazing, late grazing, and supply sufficient drinking water to the sheep, so that the sheep can eat and drink enough. After grazing during the day, they will be fed with an appropriate amount of nutritious, palatable, and digestible concentrate at night, as well as enough drinking water and salt.
3. Herd management.
Sheep in the autumn fat body strong, active, must strengthen management. When entering and leaving the gate, stop sheep to prevent crowding. Don't let sheep cross the ditch or run when grazing to prevent disability or ewe miscarriage. When entering the pasture, it is best to put the stubble field eaten on the first day, and then put the new stubble field. Grazing in the bean stubble field, the time should not be too long, to prevent excessive beans caused by bloating belly. Sorghum, corn and other regenerated seedlings are poisonous. It is strictly forbidden to graze sorghum and corn fields with regenerated seedlings after harvest, and it is not allowed to harvest such seedlings and feed sheep. Do not drink water in a dead puddle, and do not rest in a wet or muddy place to avoid infection with parasitic diseases.
Grasp breeding, protect and expand the group
In autumn, ewes have good fat condition, normal estrus, high ovulation, easy conception, which is conducive to fetal development. We should seize the opportunity to match ewes to improve conception rate and lambing rate.
1, do a good job in seed selection and matching.
The sheep use male and female sheep with more than one lamb as species, maintaining the breed characteristics of sheep with more than one lamb. Generally, the rate of double lambing of ewes with more than two births is high, so it is necessary to control the proportion of high-yielding ewes of the right age in the flock4~6 year old ewes account for the total number of sheep50%~60%is appropriate.
2, the correct mating.
The duration of each sheep estrus is24 to 40 hours, and the time of ovulation is mostly after the start of estrus.30~34Hours, so the timely breeding time should be selected after estrus12~25Hours. Aged ewes have a shorter estrus duration and should be mating early after estrus, while young ewes have a longer estrus duration and should be mating later.
In a period of estrus, mating once can generally fertilize pregnancy. However, in order to improve the quasi-fetal and multi-lambing rates, the ewes can be bred twice in the middle and end of the estrus, or at different times during a period of estrus.2~3 breeding rams each match once. If it is artificial insemination, the effect is better, which can significantly improve the quasi-fetal rate and the lamb rate.
Catch epidemic prevention and protect health
Autumn is the key period for goats to catch fat and fattening, and it is also the season of disease. It is necessary to strengthen management and strive to do a good job in the prevention and treatment of various diseases.
1. Establish a sound epidemic prevention system.
Scientific disinfection procedures should be established to kill all kinds of pathogens existing in the external environment; personnel entry and exit registration work and bathing and changing records; and full entry and full exit system should be implemented.
2, the development of scientific immunization procedures, timely vaccination.
Formulate a thorough immunization plan. It takes a certain period of time for various vaccines to produce strong immunity. Therefore, the corresponding immunization plan should be made according to the onset season of various infectious diseases, and vaccination should be carried out according to the prescribed procedures.
3, focus on prevention.
Do a good job in feeding management, enhance the individual's disease resistance; do not feed moldy and spoiled feed, do not drink sewage and frozen water, so that the sheep fat body strong, improve the individual's disease resistance.
4. Do a good job in epidemic prevention of key diseases.
In autumn, sheep are prone to diseases and affect normal growth due to a large amount of open grass and more rain in autumn. So you can deworming sheep in the fall,With Albendazole Adult Sheep5 to 7 pieces, lamb3~4Pieces. The flock is injected with Bug Buster once, each one.1~2Milliliters, except for pregnant sheep. In the deworming should also be carried out after the bath, the removal of ectoparasites. At the same time, the sheep house should be kept dry and clean, and feed residue and excrement and urine should be removed in time. Quicklime or plant ash can be sprinkled in the sheep house after rain or from time to time to absorb moisture and disinfect. Attention should be paid to ventilation of the sheep house to prevent air humidity and avoid diseases of sheep.
