Semen production and semen quality of indigenous buffalo breeds under hot semiarid climatic conditions in India

Semen Production and Semen Quality of Mehsana Buffalo Breed Under Semiarid Climatic Conditions of Organized Semen Station in India

“…Post-thaw sperm motility was not affected signi cantly by season of semen collection in the present study. Contrarily to the present study signi cant effect of season of semen collection on post-thaw sperm motility was reported by Bhave et al (2020) in the pooled data of Banni, Bhadawari, Jaffarabadi, Murrah, Pandharpuri and Surti buffaloes.…”

“…in Murrah andBhave et al (2020) in pooled data of Banni, Bhadawari, Jaffarabadi, Murrah, Pandharpuri and Surti buffaloes.Overall LSMs of sperm concentration was found as 1238.19 ± 75.57 million per ml in the present study, which was higher as compare to reported values of 766.69 ± 5.50, 1016.68, 1164 and 978.9 million per ml byBhakat et al (2011),Bhakat et al (2015),Saini et al (2017) andShakya et al (2018) respectively in Murrah buffalo. Finding of the present study was also higher than the sperm concentration reports of 838.30, 1219.98 and 1180 million per ml in Jaffarabadi buffalo byGhodasara et al (2016), Parmar et al (2020) and Bhave et al (2020); 1100 to 1200 million per ml in Swamp buffalo by Koonjaenak et al (2006); 990 and 854.27 to 1023 million per ml in Nili-Ravi buffalo by Sajjad et al (2007) and Hameed et al (2017); 920.0 ± 71.09 million per ml in Tarai buffalo by Tiwari et al (2009); 930 million per ml in Pandharpuri by Bhave et al (2020); 963.05 and 846.30 million per ml in Surti buffalo by Dhami et al (2016) and Chaudhary et al (2017) respectively and 1160 million per ml in Bhadawari by Bhave et al (2020).The LSM of sperm concentration found in the present study was lower than the earlier reports of 1610.23 ± 142.07 million per ml(Selvaraju et al, 2008), 1343 million per ml(Pathak et al, 2018) and 1310 million per ml (Bhave et al, 2020) for the Murrah buffalo; 1365.15 ± 120.23 million per ml(Dhami and Sahni, 1994) for the Jaffarabadi buffalo; 2335.7 to 3550.5 million per ml(Ahmed et al, 2018) for the Nili-Ravi buffalo; 1246 million per ml(Pathak et al, 2018) and 1270 million per ml(Bhave et al, 2020) for Surti buffalo and1310 million per ml (Bhave et al, 2020) for Banni buffalo.The sperm concentration was signi cantly (P ≤ 0.01) higher in farm-1 (1394.10 ± 83.89 million per ml) as compare to farm-2 (1082.29 ± 77.64 million per ml). The nding of the present study on sperm concentration was in accordance with study conducted byHameed et al (2017) in Nili-Ravi buffalo who reported signi cant effect of districts on the sperm concentration.The nding of the present study revealed no signi cant (P > 0.05) effects of season of birth on sperm concentration.…”

Physico-Morphological Characteristics and Oxidative Markers of Fresh Semen of Gir Bulls

“…The overall mean HOST reacted spermatozoa was 79.58 ± 1.01 % with a range of 70 to 85 %, and acrosomal integrity was 91.21 ± 0.52 % with a range of 84 to 96 %, among the four bulls, which did not differ significantly (Table 1). Similar findings were observed by Ray and Ghosh (2013) in Sahiwal bulls, and Patel et al (2020) and Chaturvedi et al (2021) in Gir bulls, while Bhave et al (2020) recorded very low HOS reactive sperm (55.13 ± 0.005 %), and Dhami et al (2018) reported higher HOST reacted spermatozoa (82.54 ± 0.91 %) in Gir bulls. The HOST reactive spermatozoa had highly significant (p<0.01) positive correlations with individual motility and viability and significant (p<0.05) positive correlations with mass motility and acrosomal integrity, while acrosomal integrity had significant positive correlations with individual motility and viability (Table 2).…”

“…This is a normal physiological mechanism to compensate the total sperm output per ejaculate. Similar findings were also observed in Gir bulls by Chaudhary et al (2017), Das et al (2017), Dhami et al (2017), Chikhaliya et al (2018), Bhave et al (2020). In contrast, Shelek and Dhami (2001) reported lower ejaculate volume as 4.84 ± 0.16 mL, while Rana and Dhami (2004) reported comparable sperm count, but higher ejaculate volume of 7.03 ± 0.44 mL in Gir bulls.…”

Transcriptome analysis of the testes of male chickens with high and low sperm motility

“…Chicken is an economically important livestock product. The reproductive performance of breeding males has a significant economic impact on the poultry industry, and semen quality is an indicator of the reproductive performance of males ( Bhave et al, 2020 ; Tesfay et al, 2020 ). Nonetheless, international standards for evaluating chicken semen quality are currently unavailable, and the present study intended to fill this gap.…”
