Abstract:
The aim of the present study was to compare the fertility results of artificial insemination performed with liquid boar semen diluted in Farmer friendly Boar Semen Extender (FBSE) stored at refrigeration temperature (5-8 ºC) with that of Beltsville Thawing Solution (BTS) stored at 15-18 ºC. An experiment was designed with 20 crossbred LWY sows which were randomly and equally divided into two groups namely; group F and group B based on the semen diluents used (FBSE and BTS). The semen was utilised within 24 hours after collection. Fertility results were measured by evaluating farrowing rate, litter size at birth and at weaning and average individual litter weight at birth and at weaning. The farrowing rate was 60 and 80%; litter size at birth was 9.66 ± 1.08 and 9.00 ± 1.77; average individual litter weight at birth was 1.08 ± 0.05 and 1.03 ± 0.95; litter size at weaning was 6.83 ± 0.90 and 6.00 ± 0.91; average individual litter weight at weaning was 7.91 ± 0.95 and 8.00 ± 1.36 respectively, with FBSE and BTS. The results of the present study indicate that the farrowing rate was significantly higher for BTS diluted semen stored at 15-18 ºC. However, the litter size at birth and at weaning, average individual litter weight at birth and at weaning did not differ significantly (p > 0.05). In conclusion AI can be practiced satisfactorily with liquid semen stored at 5-8 ºC with 3 billion sperm per dose of 60 ml when utilised within 24 hours of dilution.
