“…In addition, lower quality of bovine cryopreserved semen has been reported as a consequence of lower C18:2 and C20:4 concentrations in spermatozoa ( Argov et al, 2007 ). The difference in C18:2 abundance in the biological matrices analyzed in the present study associate with previous results obtained by our research group in complementary experiments with water buffaloes ( Gonçalves et al, 2014 ; Santos et al, 2017 ) allow inferring that seminal plasma composition varies more immediately than sperm membrane composition due to the lipemic effect noted when animals are fed diets rich in fats ( Silva et al, 2014 ).…”

“…Some of the lipids present in the mitochondrial membranes have to be imported, at least in the form of precursors ( Monteiro et al, 2014 ). Considering the mitochondrial biogenesis and the anatomic peculiarity of sperm mitochondrial sheath, mitochondria might also benefit from changes in lipaemic profile ( Silva et al, 2014 ) and higher availability of fatty acids to increase their structural resilience during spermatogenesis. As much of the cytoplasmic mitochondria is lost during spermiogenesis, the morphological changes in 72-80 remaining mitochondria of late spermatids and sperm appear to prepare them for structurally fitting in sperm flagellum and arrange around the developing spermatid tail ( Vertika et al, 2020 ).…”

“…Recent researches on the adoption of vegetable oils or fats as alternative energy sources for ruminants have been carried out ( Esmaeili et al, 2014 ; Gürler et al, 2015 ; Moallem et al, 2015 ; Khoshvaght et al, 2016 ), which has brought attention to the inclusion of agro-industry products in ruminant feed ( Van Tran et al, 2017 ). Among such products are by-products from oil palm ( Elaeis guineensis ) fruit processing ( Santos et al, 2014 ; Gonçalves et al, 2014 ; Silva et al, 2014 ), which are available in many parts of the world. During industrialization, palm oil is extracted from the pulp and its physical refining generates a compound known as palm oil deodorizer distillate.…”

Ruminant energy supplementation with vegetable oils or fats has been standing out worldwide and oil palm processing has been receiving growing interest. This study assessed the effect of supplementation with saturated and unsaturated fatty acids from the palm oil industry on the lipid profile of seminal plasma and of the sperm membrane, as well as on the morphological and functional characteristics of raw and cryopreserved buffalo semen. Twelve purebred Murrah bulls ( Bubalus bubalis ) were assigned to the experimental groups and fed diets for 120 days with no added lipids (CONT, four bulls), or with an extra amount of 3% lipids from crude palm oil (PALM, four bulls), or from palm oil deodorizer distillate (PODD, four bulls). Semen was collected and cryopreserved every 15 days. The lipid composition of membranes and semen quality were determined after collections. Lipid supplementation did not impact feed intake (P>0.05). Diet enrichment with PALM increased the linoleic acid (C18:2,ω6) in seminal plasma. Lipid supplementation did not increase the polyunsaturated fatty acids in the sperm membrane composition, but significantly increased the lignoceric acid (C24:0). Cryopreserved semen of the supplemented bulls presented higher progressive motility (60.2 vs. 67.9 vs. 65.2%; P<0.05) and sperm viability detected by eosin-nigrosin staining (61.1 vs. 69.4 vs. 67.8%; P<0.05). Palm oil reduced major sperm defects in both raw (12.2 vs. 9.3 vs. 13.2%; P<0.0001) and cryopreserved semen (12.4 vs. 9.4 vs. 11.2%; P<0.0001). The lipids added to the diet did not impact the population of spermatozoa with intact plasma and acrosomal membranes (PI-/PSA-), but significantly increased the percentage of spermatozoa with high mitochondrial potential (25.6 vs. 31.5 vs. 32.0%; P=0.008). The results suggest that lipid supplementation based on crude palm oil or palm oil deodorizer distillate can be safely used to feed buffalo bulls and may increase sperm attributes related to male fertility.

This study evaluated the capacity of thermoregulation and its consequences on the scrotal surface temperature patterns and semen quality of buffalo bulls raised in a wet tropical climate. Eleven water buffaloes were evaluated in the rainiest, in the transitional and in the less rainy season. Air temperature and humidity were consistently high, but the animals did not show thermal stress in any season. The scrotal temperature gradient of buffalo bulls using infrared thermography was described, and three parallel and decreasing thermal bands were characterised. Sperm quality (n = 176 ejaculates) was maintained in normal parameters over the periods. Pearson's coefficients showed that sperm volume and progressive motility were negatively correlated with ocular globe, epididymal tail and minimum scrotal temperatures (p < .01). Sperm membrane integrity was negatively influenced by increases in epididymal tail and minimum scrotal temperatures (p < .01). Ocular globe temperature also showed positive correlation with rectal, spermatic cord, and epididymal tail temperatures (p < .01). Therefore, even under high temperature and humidity, the thermoregulatory system was effective in preventing heat stress and the normality of scrotal surface temperatures, spermatogenesis and sperm maturation were maintained.

This study aimed to assess the variation over time in thermal comfort indices and the behavior of physiological parameters related to thermolysis, blood parameters, and semen in natura of buffalo bulls reared in tropical climate. The study was carried out in an artificial insemination station under a humid tropical climate (Afi according to Köppen). Ten water buffalo bulls (Bubalus bubalis) were used during the 5 months (April to August) of study. The environmental Temperature Humidity Index (THId) and the pen microclimate Temperature Humidity Index (THIp) were calculated. Every 25 days, respiratory rate (RR), heart rate (HR), rectal temperature (RT), and Benezra's thermal comfort index (BTCI) were assessed in the morning and in the afternoon. A blood assay was performed every month, while semen was collected weekly. THIp did not vary over the months (P > 0.05) and was higher in the afternoon than in the morning (77.7 ± 2.6 versus 81.8 ± 2.1, P < 0.05). RR, HR, and BTCI significantly increased over the months and were different between the periods of the day (P > 0.05) but within the physiological limits. RT varied between the periods of the day and decreased over the months, being the lowest in August (37.8 ± 0.7 °C), time-impacted hematocrit, mean corpuscular volume, hemoglobin levels, and spermatic gross motility and vigor (P < 0.05). Thus, buffalo bulls reared under a humid tropical climate may have variations in thermal comfort during the hotter periods but are able to efficiently activate thermoregulatory mechanisms and maintain homeothermy, hence preserving their physiological and seminal parameters at normal levels.
