“…In the present study, overall oestrus expression of 85.3% in dairy cows and 65.0% in beef cows was recorded. This finding were in agreement with previous studies where 80% oestrus expression was recorded in dairy cows by Karki et al (2018), 83.3% in dairy cows by Hirole et al (2018) and 75.0% in beef cows by Raphalalani et al (2020) when Ovsynch protocol was used. According to Bisinotto F I G U R E 1 Depiction of a 9-day Ovsynch + CIDR protocol and TAI 55 h following CIDR removal, used to induce oestrous cycle in dairy and beef cows.…”

The objectives of this study were to compare oestrous synchronization expression and conception rate following timed artificial insemination (TAI) with frozen–thawed X‐sexed or unsexed semen in dairy and beef cows. For this study, 227 cows (dairy, n = 130 and beef, n = 97) were assigned to a 9‐day Ovsynch + controlled intravaginal drug release (CIDR) protocol. All cows were TAI using X‐sexed or unsexed semen from 8 sires. Each semen type was obtained from 4 sires [2 dairy (Holstein Friesian) and 2 beef (Angus)]. Pregnancy detection was performed on Days 35, 65 and 95 following TAI by transrectal ultrasonography and hand palpation. The proportion of oestrus expression was higher in dairy (85.3%) cows compared with beef (65.0%) cows (p < .05). Overall, dairy (X‐sexed, 61.9% and unsexed, 62.0%) cows had greater conception rates on Day 35 compared to beef (X‐sexed, 56.0% and unsexed, 52.2%) cows (p < .05). Concurrently, on Day 95, overall conception rates in dairy (X‐sexed, 41.4% and unsexed, 48.5%) cows were greater than beef (X‐sexed, 38.0% and unsexed, 37.0%) cows (p < .05). Pregnancy/embryo losses between Days 35 and 65 in dairy (X‐sexed, 33.3% and unsexed, 18.2%) cows and beef (X‐sexed, 28.6% and unsexed, 29.2%) cows were recorded (p < .05). Dairy (X‐sexed, 7.7% and unsexed, 8.3%) cows had higher incidence of pregnancy losses between Days 66 and 95 when compared to beef (X‐sexed, 5.0% and unsexed, 0.0%) cows (p < .05). Oestrous expression and conception rates in dairy and beef cows were satisfactory. Advanced reproductive biotechnologies can successfully utilize gender‐ablated semen in organized emerging cattle farming systems.

“…Time required for onset of estrus: The average time required for onset of estrus after last PGF 2 ? injection was 67.80±1.44 h. The result observed in present study for mean time required for onset of induced estrus are in agreement with findings of Hirole et al (2018) who recorded the time required for onset of induced estrus with Ovsynch protocol as 53.20±1.8 hrs and 54.60±2.44 by Ratnaparkhi et al (2020). The mean value of duration of estrus detection was 23.85±0.54 hrs.…”

“…There are many factors causing anoestrus problem in buffalo like poor nutritional status, negative energy balance, parasitic infestation, hormonal imbalance, Uterine pathology (Purohit, 2014), (Gilbert, 2011). Out of 36 anoestrus buffaloes each subjected to GPG protocols 61.11 % buffaloes exhibited behavioural estrus (Table 1) with prominent to moderate signs within mean intervals of 67.80±1.44 h. The present findings of estrus exhibition are in accordance with Hirole et al (2018). However, our findings differ with worker like Bhoraniya et al (2012), Ramkrishnan et al (2012) and Deshmukh et al (2017) who reported 100% oestrus response after GPG treatment.…”

Water Buffalo (Bubalus bubalis) is one of the premier productive animal and a major contributor to milk, meat, skin and draught power in our country. It is a better dairy animal in comparison to cattle in terms of better feed (roughage) conversion efficiency, greater resistance to diseases and higher milk fat percentage. But anoestrus is the most important cause of poor reproductive performance in buffaloes both in field condition as well as in organized farm. The percentage of anoestrus is more in rural areas mainly due to malnutrition, lack of scientific knowledge and improper management practices causing huge economic losses to the farmers. Thus this study was conducted to test the effectiveness of GPG protocols in farmers field for treating anoestrus in buffaloes with PGF2α or GnRH protocol under the field conditions. A total of 36 animals were selected from different affected villages of Mathura district with good body condition score (BCS >2.5), parity of two or above, healthy reproductive organs and history of minimum 6 months anoestrus problems after reaching the age of breeding or after calving or the last breeding were selected. The treated animals were examined by per-rectal method. Among 36 treated buffaloes, 13 were found pregnant (36.11 %) and another 9 buffaloes had become cyclic with success rate of treatment was 61.11 %.
