There are roughly three kinds of boar reproductive disorders. Loss of libido or loss; sexual desire, but not across the breeding stock, can not be mated; sexual desire, abnormal sperm, no insemination ability. Discussed separately below.
First, loss or loss of libido
Improper feeding and management, excessive mating or sperm collection, lack of exercise, unreasonable ratio of trace elements in feed, lack of vitamin A and vitamin E, aging of boar, overweight, overweight, overheated weather, testicular cells Androgen reduction and so on. Shows reluctance to approach or climb estrus.
Because the hormone secretion of the breeding pig is mainly reduced male hormone secretion, while maintaining the health of the pig, with chorionic gonadotropin 80 mg, or 100 mg of pregnant horse serum, or 80 mg of testosterone propionate, 3 kinds of medicine can be One is optional and is injected intramuscularly.
Scientific feeding of nutrients is the material basis for maintaining boar life activities and producing semen. Boar feeds are mainly high-protein, with crude protein levels of 14%-18% or higher. Vitamins and minerals should be comprehensive, especially vitamin A, vitamin D, and vitamin E. Can not use fattening pig feed, because fattening pig feed may contain sedative, hypnotic drugs, boar long-term feeding, prone to excited central numbness and unresponsive.
Creating a comfortable environment Young boars are raised in a single circle to avoid mutual crawling, premature ejaculation and impotence. Stay away from sow pens and avoid pheromone stimulation and numbness. The barracks should be spacious, bright, airy, dry and hygienic. Summer heat season should pay attention to cooling.
The boars should be started at 7-8 months of age, and 10 months of age should be used for official breeding. Early mating reduces the useful life of breeding pigs. When using a broiler, the estrus should be smaller than that of a boar. If the sow is too large, the initial breeding failure will affect the boar's libido. When training, the breeder should be careful and patient, and avoid irritating and strong actions such as whipping.
Boars should be given proper exercise and exercise once every morning and evening for 1 hour each time. Through exercise, you can exercise your limbs and shoes to ensure your body shape.
Second, boars have sexual desire. But can't mate
The reasons for this are most often seen in the penis, prepuce, inflammation, limb and foot disorders.
Penis, foreskin inflammation and pain, can not be mated, with penicillin 4 million international units, streptomycin 1 million international units, analgin l0 ml, mixed intramuscular injection, 2 times a day for 3 days. Or smear with fish ointment, erythromycin ointment.
If the foreskin is too thick, too tight, or has adhesions, surgical treatment should be performed in time to remove the foreskin and divide the adhesions.
Joint and muscle pain should be identified and treated symptomatically. Due to rheumatism, 10 ml of sodium salicylate can be used for 1 week. Or use 10 milliliters of intramuscular injection of Pacers injection. Contusions and sprains due to trauma can be used below. Natural copper, Zeeland, Angelica each 50 grams, wind, myrrh, frankincense, safflower 25 grams each, Dragon's Blood 20g, for the foam, warm wine transfer service. If the ball joint is sprained, acupuncture will be made at the Acupuncture Point, sprained at the hoof, and acupuncture will be made at Yongquan, Cuntai and Hosomen, and then wiped with warm wine.
Third, abnormal sperm without sperm
Sperm abnormalities include oligospermia, oligospermia, spermatogenesis, and teratogenic spermatogenesis. The boar's disposable semen volume is approximately 200-500 ml, with approximately 800 million spermatozoa. After microscopy, the number of spermatozoa is less than 100 million, which is less refined.
Sperm abnormalities are more common in the sequelae of heat diseases such as JE, erysipelas, pulmonary epidemics, and heat stroke. If you have a long fever, you can cause the testicles to become swollen and inactivate the sperm.
Treatment of febrile illnesses, with 800,000 units of penicillin and 500,000 units of streptomycin, mixed with compound aminopyrine injection (containing aminopyrine, Jidong, barbiturate) 5-10 ml, 1 intramuscular injection , 2 times a day for 3 to 5 days; also available Bupleurum injection (or Banlangen injection) 5 ~ 10ml intramuscular injection, 2 times a day, once every 3-5 days. In addition, with 10% sodium sulphate or camphor sulphonate injection 5 ml, intramuscular injection every other day, a better effect. Can also be used cold water, ice and other cold scrotum.
For the trial of oligozoospermia, choose one of the following methods: Jianshui orally.
