“…Ejaculate volume has been reported to increase with age in Malaysian swamp buffalo [8,20]. The average semen volume registered in the present study was higher than previously reported in younger swamp buffaloes in Thailand [12], and similar to that reported for bulls of similar age in both swamp [8,20] and riverine buffaloes. In the latter category, studies have been conducted in Murrah [21], Nali-Ravi [22] and Surti breeds [10].…”

“…meatproducing) buffalo are more scarce. Most publications reported semen characteristics of several buffalo types held in different locations but studied single ejaculates [8]. Studies examining the relationship between climatic changes and semen quality have been published for Murrah buffalo [9], Surti buffalo [10], and, at least with regard to sperm output, also for river [11] and swamptype buffalo [12].…”

“…These bulls also showed a low prevalence of sperm tail defects, in agreement with the literature which indicates that a healthy buffalo should not have more than 5%–10% of total sperm tail defects (Gopalakrishna & Rao, ; Mathias & Yusuf, ; Sukhato, Amornruji, Chanatinart, Sanithvong, & Uangvachanitgul, ). These observations have been confirmed with data from different varieties of buffalo: swamp buffalo (Jainudeen, Bongso, & Dass, and Nordin, Hilmi, & Bongso, ), Murrah buffalo (Nordin et al, ; Pant et al, ) and Nili‐Ravi buffalo (Jainudeen et al, and Nordin et al, ).…”

The current study aimed to investigate the effect of testicular artery angioarchitecture on the spermiogram parameters in Egyptian Buffalo bulls. Eight adult buffalo bulls aged between 2 and 8 years were used for semen evaluation. For anatomical studies, the masculine gonads were collected after slaughtering 30 adult bulls and prepared for injection by different masses (Urographine®, Latex and Epoxy) through the testicular artery. The mass activity of the ejaculate was assessed immediately after collection. The sperm motility in fresh bull ejaculate was more than 80%. The overall mean percentage of sperm abnormalities was <18%. The recorded sperm abnormalities were mostly secondary one including distal protoplasmic droplet, fragmented tail, detached head, detached galea capitis and bent tail. The highest percentage of sperm viability was recorded just after sperm collection (alive > 85%). The results revealed that testicular artery can be divided into three parts (abdominal, funicular and marginal parts) along its course. The coils of the funicular part forming a cone‐like structure with its base fixed to the head of the testis. Two epididymal branches to the head and tail of epididymis emanate from the funicular part which continues as pars marginalis on the lateral surface of testis before its division into the lateral and medial testicular arteries on approaching the tail extremity of the testis. The increase in the length of the testicular artery with increase in the size of the testes played a great role in the degree of complexity of the architectural vascular patterns. The degree of complexity is affected by the number of coils formed by the vessel. The increase in the convolutions of the vessel will reduce the speed of blood flow to the gonads. Thus in turn will enabling the thermoregulatory mechanism to work more efficiently and will affect the semen value.

“…Semen quality of the collected ejaculate, including the ejaculate volume, sperm motility and proportions of morphologically and physiologically normal spermatozoa, determines the quality of the processed (often frozen) semen and, ultimately, the potential fertility level achieved when artificial insemination (AI) is used (Rodriguez‐Martinez, 2000). Buffalo semen has been studied for some variables such as semen volume, sperm concentration, motility, sperm viability and sperm morphology (Kushwaha et al., 1955; Kapoor, 1973; Jainudeen et al., 1982; Sukhato et al., 1988; Nordin et al., 1990; Pant et al., 2003; Koonjaenak et al., 2006, 2007 a,b), but few studies have focused on cryopreservation or AI results (Heuer et al., 1987; Rasul et al., 2001; Sukhato et al., 2001).…”

In this study, we investigated the susceptibility of frozen-thawed swamp buffalo sperm nuclear DNA to undergo controlled acid-induced denaturation in situ, as analysed by flow cytometry, and aimed to correlate the results with sperm head morphology over three seasons in tropical Thailand. Artificial insemination (AI) doses (n = 218) from 18 AI buffalo sires, prepared between 1980 and 1989 and 2003 and 2005, were tested and compared among three seasons, the rainy season, July-October; winter, November-February; and summer, March-June. The overall mean of DNA fragmentation index (DFI) (+/- SD) was 1.84 +/- 1.68%, range from 0.19 to 7.92%, with 0.221 +/- 0.021 of the x-DFI ranging from 0.190 to 0.350 and 0.023 +/- 0.009 of the SD-DFI ranging from 0.010 to 0.070. The DFI was consistently low (range 1.40 +/- 0.21% to 2.16 +/- 0.21%; LSM +/- SEM), with x-DFI ranging from 0.216 +/- 0.003 to 0.225 +/- 0.003 and SD-DFI ranging from 0.022 +/- 0.001 to 0.024 +/- 0.001 across the seasons. The DFI was low enough to be related to high fertility potential. However, DFI values varied statistically among seasons, being lower in the rainy season (1.40 +/- 0.21%, P < 0.05) than in winter (2.16 +/- 0.21%) or summer (2.00 +/- 0.20%), and were also affected by the year of semen collection and processing (P < 0.001). The proportion of morphologically abnormal sperm head shapes was low, with no significant differences between seasons. However, DFI was significantly related to the proportion of loose abnormal sperm heads (r = 0.27, P < 0.01). In conclusion, frozen-thawed swamp buffalo sperm chromatin integrity is not seriously damaged by cryopreservation or affected by the seasonal variations in temperature and humidity seen in tropical Thailand.
