“…Similar findings were also reported, in Iraqi buffaloes by Azawi et al (2009), who reported the POF size, on the right and left ovaries as 10.78 and 11.24±2.15 mm, respectively. Barkawi et al (2009) reported the maximum diameter of POF as 14-15 mm in Egyptian buffaloes whereas Yindee et al (2011) in swamp buffaloes revealed the presence of ovulatory follicles with a mean diameter of 13.5±0.52 to 14.17±1.08 mm during the post-partum ovulations. Contrary to the present findings, Derar et al (2012) reported the POF size as 9.8±0.32 mm in Egyptian buffaloes which was much lower than the present observations.…”

An investigation was taken up to study the relationship of preovulatory follicle size at the time of first postpartum AI and CL biometry with conception using transrectal ultrasonography in 70 parous Graded Murrah buffaloes maintained under rural conditions. POF sizes were measured ultrasonographically and grouped in to small preovulatory follicle (SPF), medium preovulatory follicle (MPF) and large preovulatory follicle (LPF). Serum progesterone concentration at the time of AI and pregnancy status was negatively correlated indicating that when progesterone level declined to < 0.3 ng/ml (basal level) at the time of AI, the chances of the animal becoming pregnant was increased. The size of the POF was positively correlated to the size of the CL on day 10 in pregnant buffaloes. The overall POF diameter at the time of estrum was 12.31 ± 0.29 mm (Range 9 to 16 mm) in Graded Murrah buffaloes and 50 % of the buffaloes had POF size > 12 -14 mm. They conceived only if the POF diameter was more than 9 mm at the time of AI however there was no significant correlation between the POF size at the time of AI and conception. Thus, it was concluded that physiological maturity rather than the diameter of the follicle influenced the fertility in Graded Murrah buffaloes under field conditions.

“…The time for resumption of ovarian activity is important for reduction of post‐partum anoestrus and calving interval in buffaloes (El‐Wishy, ; Kandiel, Gad, Sosa, & El‐Azab, ; Yindee et al., ). Hormonal and metabolic changes during the peri‐parturient period and especially after calving have an important impact on post‐partum follicular development and ovulation (Hussein, Senosy, & Abdellah, ; Prakash et al., ; Terzano, Barile, & Borghese, ).…”

“…Hormonal and metabolic changes during the peri‐parturient period and especially after calving have an important impact on post‐partum follicular development and ovulation (Hussein, Senosy, & Abdellah, ; Prakash et al., ; Terzano, Barile, & Borghese, ). Earlier development of a large follicle has been associated with better resumption of ovarian activity and resulted in effective reproductive performance (Malik et al., ; Yindee et al., ; Yotov & Atanasov, ). The reported intervals between calving and initiation of follicular activity in buffaloes varied from 7 days (Presicce, Bella, Terzano, De Santis, & Senatore, ), 10 days (Lohan, Malik, & Kaker, ), 14 days (Hussein et al., ) to 30 days (Usmani, Dailey, & Inskeep, ).…”

“…Follicles >8.5 mm in diameter have been interpreted as a start of ovarian activity in Mediterranean Italian buffaloes (Lohan et al., ). The onset of ovarian cyclicity in most Thai Swamp buffaloes, however, was demonstrated by the emergence of waves of follicles (≥5 mm) with only one follicle (the 1st DF) developing up to a larger size (10.80 ± 0.20 mm) than the others (Yindee et al., ). In Murrah buffaloes, large follicles (8–10 mm) were detected for the 1st time at 24.4 ± 1.99 days post‐partum (Malik et al., ).…”

This study was designed to evaluate the dominant follicles development and the estradiol-17β concentrations in non-ovulating and ovulating post-partum buffaloes. Sixteen Bulgarian Murrah buffaloes were submitted to transrectal ultrasonographic examination from the 1st post-partum day until day 50, 3 days apart. The follicular diameter of the different categories of follicles and the ovulations was recorded. The animals were allocated into two groups: I (n = 6) non-ovulating and II (n = 10) ovulating buffaloes. Serum estradiol-17β concentrations on the days for dominant follicle registration were measured by enzyme-linked immunosorbent assay. The results were statistically processed by analysis of variance, non-parametric and correlation analysis. The mean intervals between calving and first dominant follicle detection differed significantly (p < .05) among the groups (19.5 ± 6.2 vs. 13.8 ± 5.1 days), while the mean intervals between registered dominant follicles from two successive waves were comparable. The mean follicular diameters for the same category follicles in both groups were similar. Different estradiol-17β concentrations (p < .05) for the first dominant follicle between non-ovulating (23.5 ± 7.0 pg/ml) and ovulating (33.3 ± 8.4 pg/ml) buffaloes were determined. The cumulative percentages of buffaloes with firstly detected dominant follicle and ovulating animals correlated positively (r ≥ .84; p < .05) to post-partum days. In conclusion, non-ovulating and ovulating post-partum Bulgarian Murrah buffaloes showed differences in the development of the first dominant follicle and estradiol-17β concentrations during the time of dominant follicles detection.

“…Many authors reported that the administration of hormones include PMSG, GnRH, Progesterone or hCG during early postpartum period has conception (8), (9). The effect of ovarian inactivity is including increase period of first estrus postpartum, number of services per conception, pregnancy rate and days open (7),(10),(11), (12) ,(13). The purposes of this study were to evaluate different hormonal regimes for treatment ovarian inactivity and the effects on reproductive parameters (response animal, services per conception , pregnancy rate, days open) to improvement the reproductive performance in Iraqi buffaloes.…”

The present study was performed on 153 Iraqi cow buffaloes, suffered from ovarian inactivity after 60 days from calving, in Babylon province in period from November 2012 to August 2013. The affected animals were divided into four groups randomly according to the hormonal treatment regime, 48 cow buffalo treated with 1000 I.U/I.M of PMSG in one does in day 60 postpartum, which represents the 1 st group, while the 2 nd group include 45 cow buffalo treated with 0.021mg/I.M of GnRH (Receptal) in one does in day 60 postpartum, but the 3 rd group (36 cow buffaloes) treated with hCG 1500 I.U/I.M in a single dose also after 60 days postpartum, while 4 th group (24 cow buffalo) was represented the control group(without treatment). The response animals for different hormonal treatment were 87.2%, 80%, 69.4% and 54.1% for the 1 st , 2 nd , 3 rd and 4 th group respectively. The 1 st group which treated with PMSG give higher significant differences (p<0.01) compared with other groups, also the 2 nd group (treated with GnRH) record significant differences (p<0.01) compared with 3 rd and 4 th group. The duration of response also record higher significant differences (p< 0.01) between 1 st and 2 nd group compared with 3 rd and 4 th group, while the number of services per conception was no different between all groups, but the pregnancy rate record superior significant differences (p<0.01) for the 1 st group compared with other groups and reached to 85% but the 4 th group (control group) record low ratio compared with treated groups. Finally the days open was recorded superior significant differences between 1 st and 2 nd group compared with 3 rd and 4 th group, also 4 th group record long postpartum period (175.82± 13.56 days). They concluded in this study that the hormonal treatment still an important method to treated the ovarian inactivity and this fact depends on the many reproductive parameters which involve the rate of response animals, duration of response, number of services per conception, pregnancy rate and days open.
