Abstract

A total of 12 female crossbreed pigs (Hampshire × Tenyivo) with a genetic ratio of 75:25 were raised for 28 fortnights in two different housing types, i.e., group housing (Group 1, T1) and individual housing (Group 2, T2), at ages of 42 days each. With the aim to see the effect of rearing space on the animal welfare in terms of reproduction. Pigs' average ages at first mating were 330 days and 350 days for T1 and T2, their average ages at first farrowing were 446.33 days and 465 days for T1 and T2, their average litter sizes were 6.83 and 6.00 for T1 and T2, and their average litter weights were 7.59 kg and 5.67 kg for T1 and T2, respectively. T1 and T2. Age at first mating, age at first farrowing, litter size, and litter weight results for reproductive traits showed no differences. Based on the findings, it can be said that the reproductive features of crossbred animals under two distinct accommodations in Hampshire × Tenyivo crosses with a ratio of 75:25 do not differ.

Conclusion

The study was carried out to evaluate the reproductive features of crossbred pigs grown in two different environments. Twelve crossbred pigs were separated into two groups for this investigation, T1 for group living and T2 for individual housing. All of the animals were raised utilising the same food regimen and housing scheme. The average age at first mating recorded in the T1 and T2 groups was 330.17±5.72 vs. 350.17±5.72 (days). Statistical analysis demonstrated that there was no difference between the T1 and T2 groups, regardless of treatment. The average age at first farrowing recorded in T1 and T2 groups was 446.33±5.19 vs. 465.17±15.96 (days). Statistical analysis found no differences between the T1 and T2 groups. The average value for litter size recorded was 6.83±1.01 vs. 6.00±0.58 in the T1 and T2 groups, respectively. Statistical analysis demonstrated that there was no difference between the T1 and T2 groups, regardless of treatment. The average litter weight recorded was 7.59±1.31 (kg) in the T1 group and vs. 5.67±0.5 (kg) in the T2 group. Statistical analysis demonstrated that there was no difference between the T1 and T2 groups, regardless of treatment.
