“…In all groups, a significantly higher pregnancy rate was noted in multiparous animals as compared to primiparous animals. The present findings are similar to the Khanh et al [11] who observed a higher pregnancy rate in multiparous animals as compared to primiparous animals. But they reported the non-significant difference in pregnancy rate among the primiparous and multiparous cows.…”

“…Pheromones are defined as airborne chemicals released from the feces, cutaneous glands or from urine, that are sensed by the respiratory or olfactory systems that cause endocrine response and behavioral changes [10]. In male animals, pheromones are largely released from urine and they affect on hypothalamic-pituitary-adrenal (HPA) activity of female animals [11,12]. It has been stated by exposing the cows to bulls (biostimulation) before, during, and after a GnRH-based ES protocol following fixed timed artificial insemination improved pregnancy rate in bovine animals [13,14].…”

Anestrus and unobserved estrus are one of the crucial managemental lapses in the livestock business. This research was planned to assess the efficiency of different estrus synchronization procedures with bull exposed and with non-bull exposed groups in primiparous and multiparous buffaloes at Kundhi buffalo farm Rorhi and its surroundings. Total 40 (n=20 primiparous, n=20 multiparous) buffaloes were used in this study. The chosen buffaloes were divided into two main groups, A (BE, Bull-Exposed) and group B (NE, Non-Exposed). Based on the treatments A group was further sub-divided into two sub-groups, OvSynch bull-exposed (OBE) A1 and prostaglandin bull exposed (PBE) A2. Also, B group was parted into dual sub-groups Ovsynch non-exposed (ONE) and prostaglandin non-exposed (PNE) group B2. Results of the present study showed that estrus response differed significantly among the primiparous and multiparous Kundhi buffalo in all groups (P<0.05). The overall estrus response (50% and 100%) and pregnancy rates (40% and 70%) were higher in both primiparous and multiparous animals of BE groups as compared to primiparous (60% and 70%), and multiparous animals (30% and 60%) of NE groups. The overall estrus, duration was also higher in the primiparous (22 ± 0.66 hours) and multiparous animals (20 ± 2.05 hours) of BE groups, in contrast to 16 ± 0.95 hours and 14 ± 0.84 hours of NE groups. These findings suggested that the use of bull with OvSynch protocol it could efficiently be used to improve the estrus incidence and pregnancy rate in primiparous and multiparous buffaloes as compararion double prostaglandin protocol.

“…In the present results, litter size at birth was slightly higher in treated does compared to control and this might be related to the positive influence of biostimulation on ovulation rates at insemination time (Khanh et al, 2012). Concurrently, the larger litter size of treated does suggests that biostimulation around insemination may have exerted an improvement on sperm transport (Rodríguez-de Lara et al, 2003).…”

Biostimulation and reproductive performance of artificially inseminated rabbit does (Oryctolagus cuniculus)

Biostimulation is a non-hormonal and practical technique that has not yet been widely utilised when applied immediately before insemination to improve reproductive efficiency in livestock species. This study was conducted to determine the influence of short-term male biostimulation on behavioural and reproductive performance of inseminated rabbit does. A total of 142 female New Zealand White rabbits were randomly assigned to 3 groups. Females were either exposed to male odour (Odour group) or an adult aproned male (Male group), while the remaining does that were neither exposed to the male odour nor the adult male are considered the control group. All females were inseminated after the 2 h exposure session. Conception rates were determined by abdominal palpation 12 d after insemination. The results showed that conception rate of the male odour group (79.59%) was greater than that of male presence group (76.09%) and that of the control group (68.09%). Moreover, biostimulated does showed significant behavioural activities during the 2 h exposure session compared to the control group. Although no significant differences were recognised, litter size at birth and at weaning was slightly increased in biostimulated compared to control females. Nor were there any significant difference in serum oestradiol concentrations between treated groups. Conclusively, short-term 2 h biostimulation of rabbit does resulted in the appearance of various behavioural responses followed by differences in conception rates between groups after routine artificial insemination.

“…Along with this it is also helpful in increasing the intensity and duration of estrus in animals. Primiparous cow showed longer duration of estrus (23.65 h vs 13.50 h) and more intense heat and also shows more mounting behavior (100% vs 52%) when exposed to male continuously (Khanh et al, 2012). 95% gilts displayed a standing response Page23 in the presence of boar and in absence of boar 60%.…”
