Effect of dam parity on the reproductive performance of Nigeria indigenous sows and progeny survivability rates in Enugu State, South Eastern Nigeria
Journal Title: Journal of Sustainable Veterinary & Allied Sciences - Year 2021, Vol 1, Issue 1
Abstract
The effects of parity on the reproductive performance of Nigerian indigenous sow breed, progeny survivability and mortality in a commercial breeding farm in Enugu State Nigeria were investigated in this study. One hundred apparently healthy third trimester pregnant sows were randomly assigned to four treatment groups of twenty five sows per group in a completely randomized design (CRD) according to their reproductive parities as groups I, II, III and IV representing the first (P1), second (P2), third (P3) and fourth (P4) parities respectively. This study lasted for two years. The mean number of piglets born alive (NBA) of P1 (6.00±0.71 Head) and P2 (6.00±0.71 Head) were significantly decreased when compared to P4 (8.50±0.65 Head) but showed no significant difference when compared to P3 (7.50±0.50 Head). Second parity sows recorded the highest number of piglets’ deaths after birth while P1 and P3 litters recorded the lowest deaths after birth. Mean pre-weaning survival of progenies was highest in P3 (91.43±5.09 %) and lowest in P2 (84.38±11.83 %) while mean piglet mortality was highest in P2 (15.63±11.83 %) but lowest in P3 (8.57±5.09 %). It can be concluded from this research work that PIII sows provided adequate requirements necessary for their litter nourishment, growth and survival more than the other parities. Therefore progeny growth performance was best at third parity of reproduction.
