Article Synopsis
- A new biologic treatment, Prevention-N-A, was tested for calves and shown to be effective compared to the older PS-2 preparation, significantly reducing gynecological issues in pregnant cows.
- Three injections of the biologics improved reproductive health, decreased complications post-calving, and allowed for earlier heat cycles and better fertility rates.
- In calves, the treatment also boosted growth and development, leading to heavier weights and fewer illnesses compared to untreated peers.
A study on the study of the qualitative assessment of the behavior of dairy cattle according to the VAS system (visual analog scale) was conducted in the LLP "Agrofirme "AKAS", located in the West Kazakhstan region of the Republic of Kazakhstan. According to research, it follows that different seasons of time affect the conditions of detention in different ways. So, for the maintenance of cows in the summer, the distance of avoidance at the feeding site according to test 1 and 2 is within 3 meters, whereas in spring and autumn it was 2 meters.
