Reasons and measures for the lack of sexual desire, dead sperm, and azoospermia in boars

There are many reasons why boars do not have sexual desire, low libido, dead sperm, azoospermia, and reduced sperm count. Infectious diseases include: PRRS, PR, JBE, BEP, Brucellosis, Chlamydia, etc. Non-infectious factors include lack of vitamin E and sodium selenite in feed, lack of protein or amino acids, and high temperature environment. Fever caused by any cause, stress during mating, excessive breeding, scrotal injury, cold shock of sperm, and exercise disturbance caused by any cause can lead to low or even no sexual desire. Pig e net users suggested to try the following methods:

Based on clinical information, combined with the symptoms of sows and other pigs, after understanding the effects of the immune response and wild-type infections, a preliminary diagnosis can be made to develop protocols for immunization prevention, drug treatment, or elimination.

Test the content of vitamin E, sodium selenite, and protein in the feed and the formula to determine whether the corresponding ingredients need to be added.

Any form of elevated body temperature must be promptly addressed.

To reduce the stress of young boars during breeding, avoid brutal treatment of boars, especially small boars.

Immature breeds of small boars have emerged. After understanding the causes, they can be treated with Viagra supplements and mate with appropriate, estrus-friendly, docile sows to restore self-confidence.

Pigs that are damaged by the scrotum need to be treated in time, and do not breed or collect sperm in the short term.

Create a cool, comfortable environment for boars at 17 -21 °C.

Artificial insemination workers should operate as required to avoid cold shock or death of sperm.

For boars caused by contagious factors that have no sexual desire, low libido, dead sperm, azoospermia, and reduced spermatozoa, they must be tested for safety, non-infectious, and semen quality before they can be used.
