“…Smaller sample sizes may result in greater variability among sires. The present results are in accordance with the study of Dash et al and Bhagat et al 3 , Hossain et al 4 found non-significant effect of different bull semen on pregnancy rate. CONCLUSIONS Study clearly indicates that AI operators, year of insemination & heifers have significant effect over conception rate while sire didn't make any difference in conception rate.…”

“…operators. Similar kind of study was done by Anzar et al 1 , Gokhale and Bhagat 3 and Hossain et al 4 .While Patricia et al 8 There were 6 operators which exhibited statistically significant and lower success rates than the average. It means that the performance of remaining 9 operators is comparable, since the differences are statistically insignificant in spite of insemination records & the odd ratio ranging widely.…”

The present study was carried out to study the conception rate of artificially inseminated khillar cattle with effect of sire, AI operator, Year of insemination, Lactation number under field condition. The study was conducted at different cattle development centres run by BAIF in Maharashtra state during the period from 2010 to 2014. Multivariate logistic regression method was employed to estimate conception rate from 2169 inseminations records. The overall mean conception rate was 60.58%. Year of insemination and AI operator showed significant variation in conception rate while no significant difference was found in conception rate due to sire & lactation number. Out of 15 AI operator, 9 operators were comparable, since the differences are statistically insignificant. Insemination records ranging from 60 to 209.There was no significance in lactation wise study highest conception was found in third lactation 68.43% while lowest conception rate was found in heifers 58.64%.Odds ratio of 2013 was lower (OR: 0.67) than our reference value of year 2010. Highest odds ratio found in year 2014 with estimated conception rate 59.12%. Six sires were used for current study conception rate was not shown statistically significant effect due to sire in present study. The insemination records ranged between 138 to 981.The Odds ratio of a bulls was higher than reference value however, mostly statistically non-significant. Therefore management can play important role in monitoring performance of AI operator in field condition.

“…Similarly [ 21 ], found that cows at 2 and 3 parity had a greater conception rate than nulliparous cows. Previous research has shown that pregnancy rates differ depending on parity [ 34 , 35 ]. Cows in their first three parties had advanced pregnancy rates than cows in later parties.…”

“…Triladyl is a commercial extender that might be developed in a highly controlled laboratory environment and precise concentrations of medium components. However, the better performance of TFE diluter might be due to the use of glycerol to a slightly higher percentage [14,28]. Glycerol is a widely used cryoprotectant in freeze-thawing that reduce the formation of intracellular ice crystal by entering the cells and binding with water content [15].…”

“…Several studies in Bangladesh reported lower CR in cattle due to variance in breeds and lack of appropriate semen diluents and freezing techniques. Hossain et al showed that the overall CR was only 59.29% among 224 cattle [28]. Therefore, inseminating buffalo with quality semen every time is necessary to obtain a higher conception rate.…”

Cryopreservation has been used extensively for cattle in Bangladesh, albeit no study was conducted on the cryopreservation techniques of buffalo. This study compares two freezing methods and the effects of diluters on the semen quality of buffalo. In the first freezing protocol, semen was frozen in two-step: from 37 °C to 5 °C for 30 minutes in a BLRI-developed equilibration chamber and from 5 oC to -120 oC in a Styrofoam box using liquid nitrogen vapor from different distances (0.5, 1.5, 1.6, 2 and 3 inches). At the same time semen was frozen in a programmable freezer in three steps. The semen samples were then evaluated for motility and morphological quality by CASA. In another experiment, the efficacy of one locally developed diluter-Tris-fructose-egg yolk-based (TFE) and three commercial diluters (Andromed, Triladyl and Steridyl) were evaluated. The highest number of motile sperms (62.67±1.12; P< 0.01) and progressive motility (38.97±1.10; P < 0.001) was observed at 1.6 inches above liquid nitrogen. There was no significant difference in overall motility, progressive and slow motility between semen cryopreserved in the cheap nitrogen vapor technique (57.49±5.67, 38.70± 4.04 and 3.83± 0.63, respectively) and expensive automated technique (65.94±4.65, 45.54 ± 3.64 and 2.43± 0.36, respectively). The highest recovery rate and conception rate were observed in semen diluted with TFE (82.4% and 80%, respectively). Hence, the cryopreservation technique using nitrogen vapor and TFE diluent is cost-effective and suitable for freezing buffalo semen that would produce superior semen for artificial insemination.
