Abstract

The optimal reproductive performance of cows was reflected by the low of Service per Conception, high pregnancy rate, and short postpartum estrus. So, the production of calf that was born every year would increase, so that the population and cows’ productivity were high. The high population of cows would cause the animal protein was available sufficiently. There were some alternatives to shorten postpartum interval to first estrus that indirectly was the improvement of feed, both quality and quantity in order to the reproductive organs got the function optimally, while which directly was by reproductive hormone injections (PGF2α) and uterine manipulation to accelerate the uterine involution. The hormone distribution to people’s cows needed to be considered, because the price was quite expensive for the breeders and the distribution had to be in veterinary’s supervision. The treatment which was like injection PGF2α was uterine manipulation, it was simpler and more economical. The aim of this research was to know the reproductive status of postpartum cows that did not have korpus luteum to be sample of this research, to know the effect of uterine manipulation to the first postpartum estrus, the uterine involution, the presence of PGF2α and the difference of variety toward appearance of the first postpartum estrus, and to know the effect of uterine manipulation toward livestock fertility rate. (b1) This research had been done in Bungo and Tebo Regency, Jambi, since September 1st, 2009 to September 5th, 2011. This research was conducted by using Factorial Randomized RAL 3×2×4 on treatment of Factor A manipulation for 0 minute (a0), 1 minute (a1) and 2 minutes (a2), whilst treatment of Factor B primiparous cows (b1) and multiparous cows (b2), which each was repeated as 4 times. This research was done by 3 phases survey and laboratory method. The first phase research was done by survey method that aimed to identify which livestock to be sample of this research. The second one was in breeders’ barn by manipulating the uterine and taking blood to be checked in laboratory to know the effect of the treatment to the first postpartum estrus and to look the presence of PGF2α after the treatment. Whereas the last phase was done in the barn to know the effect of uterine manipulation toward the livestock fertility rate. The parameters which were observed; the percentage of female postpartum Bos Sondaicus that did not have korpus luteum, the first postpartum estrus, level of hormone PGF2α of the blood, the length of reproductive tract from bivurcasio to vulva, the mating rate (S/C = Service per Conception, the pregnancy rate (CR = Conception Rate). The result showed that the reproductive status of sample for 92, 41%, the effect of factor A was very real (P<0,01) toward the first postpartum estrus and the effect of pregnancy rate was real (P<0,05) toward the conception rate, but was not real (P>0,05) toward the length of reproductive rate but the conception rate was real (P<0,05) toward pregnancy rate. While interactive treatment among factor A and B, the effect was not real (P>0,05) toward all parameters that were observed. Conclusion: The effect of uterine manipulation showed that the best treatment of factor A was W1 while factor B was multiparous on parameter of pregnancy rate (78,25%). Interaction among factor A and B did not cause difference toward all parameters that were observed.
