How boars maintain their superiority
As the saying goes, sows are good and they have a good nest. Boars are good and they are good. Keeping good boars mainly produces high-quality semen and produces excellent offspring. So, what are the conditions that affect boar libido and semen quality? One is the thermal stress caused by hot weather, the second is the physiological metabolic dead sperm that is not used for a long time, and the third is the stress caused by illness or injection of vaccine; these three phenomena will cause the boar semen quality to decrease. When the ambient temperature is higher than 32°C, the boar's libido declines rapidly, and the sperm's vigor is reduced. The testis' heat dissipation is difficult and the local temperature is higher than the normal temperature. In this way, sperm metabolism is accelerated and the death rate is accelerated. In addition, boars that have not been used for a long period of time have similarly reduced libido, deteriorated semen quality, and increased spermatozoa and deformed spermatozoa in semen, often resulting in non-pregnant sows. In addition, the response of pigs to a fever or vaccination can also lead to reduced sperm motility or dead sperm. Management points: First, on the basis of strengthening the management of boars, regular inspection of semen quality is a key measure to ensure the effective fertility rate, especially in the summer, after the disease or after the vaccine, but also to strengthen the testing. Secondly, the boars should be collected regularly and should not be left idle for a long period of time. If using boars that have not been harvested for a long time, the semen collected for the first time should be discarded. The third is to establish a fine boar management process that can maximize the potential of boar germplasm resources. Such as: create a suitable environment, reasonable exercise, correct use, regular insecticide epidemic prevention, regular physical examination (weight, piggyback, antibody monitoring, etc.).
