Description
These study compares farrowing rate and litter size in AI sows after cervix stimulation with catheter or fence-line boar contac around
insemination. Within firs 7 days after weaning, the total of AI 149 sows were divided into three groups. Group I: cervix stimulation with catheter immediately before and after sperm deposition (n=49), Group II: fence-line boar contact immediately before, within and after insemination (n=50), Group III: not treated, control, sows (n=50). Farrowing rate were significant higher (P<0.05) after cervix stimulation (90%) or stimulation by boar presence (86%), compared with control sows (78%). These value were not significant
differ (P>0.05) among the stimulated swos (Group I and II). Performed treatments has no significant effect on litter size. These results indicate that cervix stimulation or boar presence at AI can be useful method to improve sows fertility.
