ANALYSIS OF THE EFFICACY OF SUPRAPHYSIOLOGICAL DOSES OF OXYTOCIN ON SOWS AND THE STATE OF PIGLETS
The article presents the data from an experiment on the use of supraphysiological doses of oxytocin to sows in the early postpartum period. For its implementation, three groups of animals were formed. The animals of the experimental group 1 were injected with oxytocin once within three days after farrow at a dose of 75 IU, the animals of the experimental group 2 - similarly, oxytocin was injected twice within three days, the animals of the control group 3 were not administered hormonal drugs of myotonic action. It has been established that the use of oxytocin at a dose of 75 IU once or twice within three days after farrow helps to reduce the pathology of the uterus and mammary gland, prevents violations of milk flow, increases the secretion of colostrum (milk), which ensures high livability of piglets for weaning. Thus, in the experimental groups, a decrease in postpartum complications of an inflammatory nature was recorded by 26.67 - 33.33 %, an increase in the livability of piglets at weaning - by 5.96 - 7.36 %. The introduction of oxytocin at supraphysiological doses does not affect the increase in the concentration of immunoglobulins in the colostrum of sows and, as a result, does not change their blood serum level in piglets.
