The aim of the p.esent study was to evaluate the imp.ct of the technological level in small-scale dual-p.rp.se cow-calf Bos indicus female op.rations on the resump.ion of the ovarian activity p.st-p.rtum. A total of 13 small scale dual-p.rp.se Bos indicus × Bos taurus op.rations were included in this exp.riment and they were classified according to their technological status as: high technological status (HT), medium technological status (MT) and low technological status (LT). Ninety-three mature cows were treated with either a CIDR (controlled internal drug release device) with estradiol benzoate (CIDR+EB) or alone (CIDR). At day 9 all animals received intravaginally a CIDR for nine days. At day 0, the CIDR was withdrawn and 24 hours later one dose of estradiol benzoate was administered to 51 cows (17 in HT, 17 in MT and 17 in LT), the remaining animals (n = 42) did not receive the estradiol benzoate administration (14 in HT, 13 in MT and 15 in LT). Comp.risons were p.rformed on serum p.ogesterone concentrations after CIDR treatment. By day 7 after imp.ant withdrawal, the p.op.rtion of cows that resume ovarian activity detected by p.ogesterone concentration increased in all technological level farms, no statistical main effect was observed within technological level. By day 17 there was a significant main effect of technological level (p.= 0.05) on the p.op.rtion of animal that resumed the estrous cycles, but neither a main effect of treatment (p.= 0.97) nor an interaction between technological level and treatment (p.= 0.98). Furthermore, technological level of the farm showed a tendency (p.= 0.07) to affect that resume the estrous activity, and a significant effect of treatment was observed (p.= 0.005) but no interaction between technological level and treatment. The p.op.rtion of cows that showed estrus was different across technological level (p.= 0.02), the highest p.op.rtion of cows showing estrus regardless of treatment was in the H

Azteca Breed Horse Ep.didymal Sp.rm Evaluation: A Comp.rison of Head, Corp.s and Cauda Sp.rm Quality

The main objective of this study was to determine differences in sp.rm recovered from the three segments of the ep.didymis, i.e., head, corp.s and cauda, using routine measurements of sp.rm quality and DNA fragmentation assessment. There was a larger sp.rm concentration (p.p.rm/mL) comp.red with the corp.s and cauda. The p.rcentage of normal morp.ology was higher in the cauda but had lower motility (p.p.rm obtained from the head and body of the ep.didymis (p.p.red with the cauda. The DNA fragmentation index values were 12% higher (p.p.red with DAp. stain in sp.rm from the head and corp.s of the ep.didymis, but similar in the cauda. Sp.rmatobioscop. p.rameters match the maturation changes that occur in the ep.didymal tract with higher quality sp.rm being from the cauda, but with a lower concentration comp.red to sp.rm found in the head.
