Abstract
1.The present study was conducted on 73 sows of "T & D" breed distributed in six groups.
2. Different treatments viz., Gestaforte vet bolus, Uterotone liquid, Betadine liquid along with Payapro bolus and Betadine liquid in four different treatment groups were administered within 24 hours of farrowing. Two groups were kept as control.
3. Highly significant effect (P < 0.01) of treatments on weight of piglets at various ages was recorded during pre-weaning periods from birth to 56th day of age.
4. Significant influence of treatments on litter weight was noted at different ages during pre-weaning periods except at birth,
5.Significant effect of Gestaforte vet bolus on average litter weight was noted at 10th, 20th, 30th, 40th, 50th and 56th day of age, except at birth in comparison to the subsequent farrowing in which no treatment was given.
6. Non-significant effect of treatments on litter size was recorded at all the ages during pre-weaning period.
7. Non-significant difference with regard to litter size was found between treated and subsequent farrowing non-treated sows in all the four treatment groups at all ages except at 10th day in group T₂.
8. The shortest interval of fertile estrus (10.58 1.86 days) was also observed in group T However, non-significant effects of various treatments on the interval of fertile estrus was observed.
Farrowing interval was lowest (179.581.91 days) in group T, in which Betadine liquid intrauterine was administered. However, non-significant effect of treatments on farrowing interval in sows was observed.
10. Non-significant difference in the average percentage of still born piglets in all the treatment groups was observed.
11. Non-significant effect of treatments on mortality percentage of piglets at different ages was indicated. Non-significant difference in mortality rate in treated and untreated next farrowed piglets in all the treatment groups at all ages was recorded.
12. Post farrowing intrauterine therapy reduced duration of fertile estrus and farrowing interval but higher piglet weight at weaning was recorded with oral therapy groups.
13. The difference in return from the sale of piglets just after weaning was Rs. 394.80 and 283,50 in groups T, and T, respectively. The anticipated net extra return in T, and T, groups were found to be Rs. 3,51,016.00 and Rs. 1,82,644.50 respectively.
14. Oral therapy groups of sows showed higher profitability in comparison to intrauterine therapy groups of sows.
