“…The result of this study also showed that older cows produced a greater concentration of progesterone (Table 6). It was previously explained that estrous behavior had a positive relation with age and parity (Frade et al, 2014). Additionally, concentrate supplementation did not affect progesterone profile on day 1 to day 17.…”

This study aimed to evaluate the effects of concentrate supplementation containing different protein levels on estrous signs and progesterone profiles of two age groups of Ongole Grade cow. Thirty females cows were grouped according to their ages (G1= 25±1.6 months; G2= 37±1.7 months), where each group received 3 dietary treatments with 5 replicates. The dietary treatment was based on CP levels of total mixed ration (TMR) (T1= 7.41% CP; T2= 8.23% CP; and T3= 9.17% CP). The cows were synchronized using PGF2α and GnRH, followed by time-fixed artificial insemination (TAI) using frozen semen. Data on nutrient intake and progesterone concentration were subjected to a randomized complete block design of ANOVA following a factorial arrangement of 2×3 while data of estrous signs were analyzed using non-parametric methods of Kruskal-Wallis and independent t-test. The results showed that there was a significant interaction effect between age group and dietary TMR treatment on CP intake and TDN intake in which the highest intakes were found in older cows (G2) fed TMR at 7.41% CP (T1) (p<0.01). Dry matter intake (DMI) was not affected either by age group or level of concentrate supplementation. Results also suggested that estrous signs, including vulva redness, swollen vulva, and mucus discharge, were higher in older cows (G2) than in younger cows (G1). In addition, interactions were also found on progesterone levels, whereas younger cows (G1) fed TMR with 9.17% CP (T3) showed the highest concentration of progesterone on d 5, 17, and 21 (p<0.01). In conclusion, this study suggests that younger cows receiving the highest CP diet (T3) result in higher progesterone concentration during the experimental period. Therefore, it is important to fed sufficient dietary CP especially for cattle in early reproduction period to optimize the reproductive performance.

“…thus more total embryos collection because more total structure ovarian were recovered. According to [41] that a positive correlation was found between the number of follicle responsive to pFSH (2-8mm) at the beginning of treatments and the super ovulatory response, and no differences were found in these follicular population between two treatment groups. .…”

The objective of this research was to evaluate the effect of FTAI on embryo production that used GnRH plus progesterone combination to synchronize ovulation of 3 different parity of donor from local pesisir cows in west Sumatra. This study used timed embryo transfer program using GnRH plus progesterone combination in 3 local pesisir cows and 2 cows in time embryo program using estradiol plus progesterone of donor. Ovarian ultrasonography was performed on d 0 (time of AI) and at flushing to determine ovulatory diameter and ovulation. On d 0 at the time CIDR implant + PGF2α injection and on d 7 started ovsynch protocol administrated by injection GnRH and FSH for FTAI without detection estrus. The number and the quality of embryo was evaluated to determine the fertility of pesisir selatan cows. The result showed that the expression of estrus cows tend to high ovulation rate. The diameter size of a follicle was range from 5 to 15 mm with 10.67±2.96 mm in GnRH plus progesterone and 5 to 14 mm with mean was 8.75±2.05 mm in estradiol plus progesterone (P<0.005). The number of follicle ovulation was 27 in treatment A and 18 in treatment B (P<0.05). The number of CL and embryos was higher in treatment A. CL was 19, with 18 embryos and in treatment B was 9 with 6 embryos. The quality of embryo range from 1-4 grade with the transferable embryos was higher in treatment A than treatment B (P<0.05). There was the linear regression between ovular follicle, CL and number of embryos recovery of local pesisir cows. It was concluded that equal numbers of embryos and transferable embryo by using GnRH plus progesterone combination of local pesisir cows.

“…An adequate uterine exposure to E2 affects positively the fertilization process [12], reduces the incidence of early luteolysis [13,14], and provides an uterine environment favourable to the establishment of pregnancy [15,16]. Regarding P4 concentrations during diestrus, the relationship between P4 concentrations and fertility are generally positive [3,6,17]. Progesterone is critical for successful maternal recognition and maintenance of pregnancy [18,19].…”

Impact of estradiol cypionate prior to TAI and progesterone supplementation at initial diestrus on ovarian and fertility responses in beef cows

et al. 2017

In cattle, early diestrus progesterone (P4) supplementation modulates endometrial function to exert pro- and anti-pregnancy establishment effects; specifically, P4 stimulates conceptus growth, but also induces early onset of luteolysis. This paradoxical effect is frequently related to the inconsistent fertility outcomes that result from P4 supplementation experiments. Aim was to investigate the impact of exogenous estradiol (E2) treatment at the end of timed fixed AI (TAI) on frequency of early luteolysis and pregnancy of beef cows supplemented with P4. Ovulations (D0 of study) of suckled multiparous (n = 643) and primiparous (n = 193) Nelore cows (Bos indicus) were synchronized with an E2/P4-based protocol for TAI and assigned to receive 1.0 mg of estradiol cypionate (CP) or nothing (NoCP) on D-2 and 150 mg of injectable long-acting P4 (iP4) or Placebo (NoiP4) on D4 on a 2 × 2 factorial arrangement. On D15, the iP4 supplementation increased (P < 0.05) the frequency of early luteolysis (NoCP + iP4: 26.0%; [13/50] vs. NoCP: 8.0% [4/50]), but CP prevented this effect (CP + iP4: 8.3% [4/48] and CP: 6.4% [3/47]). The CP improved pregnancy/AI (P/AI) of multiparous (CP: 51.6% [165/320] and NoCP: 35.0% [113/323]; P < 0.001) and primiparous cows (CP: 40.4% [40/99] and NoCP: 24.5% [23/94], P < 0.05), regardless of iP4 treatment. The iP4 supplementation affected P/AI of CP and NoCP treated cows according to follicle size at TAI. For the CP treated cows, the iP4 supplementation improved P/AI of sub-populations of cows with follicles <12.35 mm (42.0% [34/81] vs. 53.1% [34/64]), while for NoCP treated cows, the improvements occurred in subpopulations of cows with follicles ≥12.35 mm (46.1% [35/76] vs. 58.7% [37/63]). In conclusion, strategies associating E2 and P4 supplementation decrease the incidence of early onset of luteolysis and improve P/AI of suckled beef cows with smaller follicles.
