In the autumn, the plants are abundant, the herbs are ripe, the seeds are full, the nutrition is rich, and the weather is cool and pleasant. It is the good season when the sheep only grasps the breeding of the autumn pheasants and the ewes and should do a good job of management.
Grazing grazing, Bao Qiu
1. Select ranch. In autumn, shepherds should choose mountainside pastures or Pingchuan mountainous areas where the terrain is high and winter is unavailable. In late autumn, the air turns cold and it is necessary to graze as much as possible in the grassy gully so that the sheep will walk less and eat more grass.
2. Grazing time. At noon in the autumn, the sunlight is strong and the temperature is high. Sheep are prone to heat stroke and grazing should be avoided at noon. Graze early, collect the sheep lately, and provide enough water for the sheep to feed and feed the sheep. After returning from the grazing during the day, it will be supplemented with adequate amounts of nutrients, good palatability, good digestive feed, and sufficient supply at night. Drink water and add the right amount of salt.
3. Flock management. Sheep tend to grow up in the fall and are active and must strengthen management. When going in and out of the lap, you must block the sheep to prevent overcrowding; do not allow the sheep to cross the ditch and run while grazing, to prevent disability or miscarriage of the ewes. To enter the ranch, it is best to put the crickets that have been eaten for the first day, and then put in the new land. Grazing in soybean meal, the time should not be too long to prevent the excessive consumption of beans caused by swelling. Sorghum and corn are poisonous. It is strictly forbidden to grazing in the sorghum and corn fields with regenerated seedlings after harvest, and it is impossible to harvest such seedlings to feed sheep. Do not drink water in a puddle, and do not squat in wet or muddy areas to prevent infection with parasites.
Grasping and breeding, Bao extended group
Autumn ewes have good sensation, normal estrus, more ovulation, easy fetal development, and favorable fetal development. They must seize the opportunity to breed ewes to improve the conception rate and lambing rate.
1. Do a good job matching seed selection. The sheep uses a litter of male and female rams as a species, keeping the breed characteristics of the lambs of one lamb. Generally, the rate of twin lambs of the second-born or above is high. Therefore, it is necessary to control the proportion of high-yielding ewe in the flock. It is advisable that 4-6-year-old ewes account for 50%-60% of the total number of sheep. .
2. Correct breeding. Each time the estrus duration of the sheep is 24 to 40 hours, and the ovulation time is 30 to 34 hours after the onset of estrus. Therefore, the appropriate 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.
In one estrus period, fertilization can be completed by fertilizing one at a time. However, in order to increase the quasi-fetal rate and the odd-numbered rate, two breedings can be performed during the middle and late stages of estrus estrus, or two or three breeding rams can be used each at one time during one estrus period. 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.
Grasping the epidemic and keeping health
Autumn is a crucial period for goats to catch fattening and fattening, and it is also a frequent occurrence of diseases. We must strengthen management and strive to do a good job in the prevention and treatment of various diseases.
1. Establish a sound immunization system. It is necessary to establish a scientific disinfection program to kill various pathogens that exist in the external environment; to enter and leave the registration work and bathing and dressing records; to implement all-in and all-out systems.
2. Develop a scientific immunization program and conduct vaccination on time. The establishment of a thorough immunization plan and vaccination with various vaccines will take a certain period of time to produce strong immunity. Therefore, according to the seasonality of various infectious diseases, a corresponding immunization plan should be prepared and inoculated according to prescribed procedures.
3. Focus on prevention. Do a good job of feeding and management to enhance the individual's ability to resist disease; do not feed moldy feed, drink water and frozen water, make sheep fat and strong, and improve the individual's resistance to disease.
4. Grasp the epidemic prevention of key diseases. In autumn, because sheep only eat a lot of open grass fodder, and more rainfall in autumn, sheep are susceptible to disease and affect normal growth. Therefore, the insects can be repelled in autumn, with 5 to 7 adult lambs and 3 to 4 lambs with albendazole. The group of sheep was injected with insect nemesis once and injected with 1 to 2 ml each, except for pregnant sheep. Medicinal baths should also be taken after deworming to remove ectoparasites. At the same time, the sheep house should be kept clean and dry, remove feed residue and excrement in time, and sprinkle lime or ash in the sheep house after the rain or irregularly to absorb moisture and disinfect. Pay attention to the ventilation and prevent the air from being wet. Avoid disease in sheep.
