First, the basic quality requirements
1. Body appearance. In accordance with the basic species-specific characteristics of cultivars, rams require good testis development, uniform symmetry, flexibility, good libido, and no defects. The ewes required good breasts, elasticity, no induration, good motherhood, and normal estrus cycle.
2. Grade requirements. To achieve the basic species level requirements, the ram is guaranteed to be above the first level sheep, and the ewes are guaranteed to be above the second level sheep.
3. Health requirements. The introduction of breeding sheep is in good condition, healthy and disease-free, without any bad genetic diseases. Do not introduce weak sheep, sick sheep and infertile sheep.
4. Age requirements. Generally, it is advisable to use a sheep of 1 to 1.5 years old. Sheep of this age not only have strong anti-stress ability, but also have greater plasticity due to immature development. After introduction, it is easy to acclimate and adapt to the new environment, the use of a long period of time, at the same time, easy to observe and select when introduced.
Second, the selected treatment
Marked selected sheep, isolated during feeding, focus on the injection of foot-and-mouth disease, goat pox, infectious pleuropneumonia and other vaccines, combined with antibody testing, to achieve the level of immune standards, can be considered for introduction. When a small number of introductions are made, reference is made to viewing seed-related immunization records as a reference, focusing on quarantine of PPR, foot-and-mouth disease, Brucellosis, etc. to ensure the health of the breeding sheep.
Three species of goats placed and after attending nursing
After the introduction of the species of goats, the animals were unloaded and counted. According to age, gender, body size, etc., organize groups. Placed in pre-cleaned and disinfected housing and disinfected vehicles.
After the sheep enters the field and rests fully, it arranges for the first time to freely drink water. The water temperature is moderate and the amount is suitable. Drinking water is best to add appropriate amount of electrolytic multidimensional, astragalus polysaccharide, etc., can effectively help restore physical fitness, improve disease resistance. After one week, change to normal drinking water. After 2 to 3 hours of drinking water for the first time, start feeding the high-quality mixed forage. It is not appropriate to feed grass or hay alone. The mix ratio of grass and hay is 2:1. The first feeding amount should not be too much, and it is sufficient to feed it until it reaches 67%. After 3 days, it can be turned into feeding soft, tender and easily digestible forage, and gradually increase the amount of feeding, allowing it to freely food. Keep for 30 days in isolation and keep quiet, comfortable and well cared for, reducing adverse stress.
IV. Inspection during the period of isolation
After long-distance transportation, the physical loss of the goats is serious, the digestive system is disordered, and the disease-resistant function is reduced, which easily induces various diseases. Therefore, we must carefully observe the sheep's spirit, feeding, drinking, sports, and excrement. If abnormal phenomena are found, appropriate effective measures must be taken in time to control the development of the disease. The performance of cough, runny nose and other symptoms can not be treated only by the common cold, but also combined with bronchitis and pneumonia and other diseases for comprehensive prevention and treatment; the performance of infectious impetigo, conjunctival keratitis, convulsions, Sheep infected with contagious pleuropneumonia and other infectious diseases should be promptly isolated and treated to prevent the spread of the epidemic.
V. Feeding management
After being kept in isolation for 30 days, the herds recovered and recovered. At this time, blood tests can be performed in a place where conditions permit, and after routine health checks, routine disinfection, deworming, and reimbursement are performed. Two weeks after immunization, the breeding sheep can be transferred to the production area and put into production and application. The dead animals in the isolation period are strictly treated as harmless.
