“…According to the decreasing frequency of occurrence, behaviors expressed by bulls presented to a restrained dummy female from the beginning of the interaction up to seminal collection were: smelling the vulva, Flehmen reflex, incomplete mating (animal exposes the penis, but does not ejaculate), licking the vulva, mounting without penile exposure, intermittent exposure of penis prior to mount, chin rump resting and head beat on female body parts. These behaviors were also reported in studies by Anzar et al (1993) and Samo et al (2005). Johari (1960) draws the attention to the occurrence of Flehmen reflex and repetitive small penile movements with a projection of the penis by a few centimeters out of the preputial ostium.…”

The aim of the present review is to provide complementary information about reproductive characteristics of male buffaloes having as perspective a four -year-study based on a weekly seminal collection schedule and collection of data in partner properties of several regions of Brazil. Aspects of testicular growth, reproductive behavior and characteristics of 1477 ejaculates of 13 donors are discussed in conjunction with data available in the literature.

“…Libido is defined as the willingness and eagerness to mount and to complete copulation (Hultnas, 1959) and mating ability can be characterized analyzing the posture of the male during mount, ejaculation and dismount (Chenoweth, 1981;Anzar et al, 1993).…”

“…Differences in libido scores were also observed between breeding lines and sires-within-lines in young bulls of British breeds (Perry, 1990), and sire strongly influenced serving capacity in young Angus bulls (Ologun et al, 1981). Anzar et al (1993), in a study on forty-four buffalo bulls determined that semen production was correlated with sexual behavior in only the fair and poor categories of buffalo bulls (r=0.84, P<0.005). In the study that was performed for libido examination of Belgian Blue and Holstein Friesian bulls by Hoflack et al (2006), it was expressed that regarding the breeding soundness evaluations (BSE) trait semen evaluation, significantly more Belgian Blue bulls failed the BSE as a result of poor sperm quality compared to Holstein Friesian bulls, and the average breed scores for progressive motility and for sperm morphology both indicated a relevant difference in the advantage of the Holstein Friesian breed.…”

This study was conducted on 10 crossbred rams consisted of 5 ArkharMerino×Moghani (AM×MG) and 5 Baluchi×Moghani (BL×MG), to analyze correlation between semen characteristics and libido activity. The semen samples were evaluated for semen volume, total sperm per ejaculate (TSE), spermatozoa concentration (SC), color, wave motion, spermatozoa progressive motility, percentage of live and abnormal spermatozoa, pH, rate of metabolic activity of spermatozoa and semen index. The libido of rams was measured by two indices including reaction time (RT) and refractory period (RP). While RT only had a negative and significant correlation with semen volume (r=-0.15, P=0.04), but RP had a significant correlation with seminal traits except for TSE. Moreover, libido test scores between two genetic groups did not have a significant difference (P<0.05). Considering the observed significant correlation between RP and semen characteristics, we suggest that a reliable monitoring with the aim of detecting rams of poor semen quality and libido seems worth making an effort for the future of the herd. In summary, the reported correlation between libido and seminal traits will confirm the importance of simultaneous selection for both libido and semen quality in the herd. Finally, the importance of performing an individual evaluation of semen and libido for each male and for using a ram in breeding programs is highlighted, due to the existence of differences among rams as well as a low correlation between semen characteristics and libido indices.

The effect of dietary supplementation of Cu and Zn on semen quality parameters and certain bio-chemicals parameters were evaluated in Murrah bulls. Twelve mature Murrah bulls (4-6 years of age) were divided into three groups (n=4) T1, T2, and T3 based on semen volume and concentration and were fed as per ICAR standard (2013). However, the animals were supplemented with 0%, 25%, and 50% Cu and Zn above the basal diet in T1, T2 and T3 groups, respectively for 180 days. Quantitative and qualitative characteristics of semen, blood and seminal plasma antioxidant status, blood and semen minerals (Cu, Zn, Ca and Mn) were determined in experimental Murrah bulls. Semen ejaculate volume (mL) increased in T2 and T3 while sperm concentration (million/mL), intact acrosome (%), HOST reacted spermatozoa (%) increased in T3 group compared to T1 and T2 groups. No difference was observed in mass motility, pH, live spermatozoa (%) in semen sexual behaviour except dismounting time which was decreased in T3 than T1 and T2 (plessthan0.05). SOD activity in blood plasma and LPO activity decreased in seminal plasma in both T2 and T3 groups than T1, whereas catalase activity did not show any significant difference. Cu and Zn supplementation in T2 group improved plessthan0.05) Zn level in blood and seminal plasma and Cu level in blood plasma only, but not in seminal plasma. Therefore, it can be concluded that supplementation of Zn and Cu at 50% above the recommended levels of ICAR (2013) improved the qualitative and quantitative attributes of semen in Murrah bulls.
