“…In Estradoublesynch protocol, the mean plasma protein levels on the day of FTAI and day 12 post-AI were significantly (p<0.05) higher compared to day 0 and 9 of the protocol. Recent studies [ 13 , 33 - 34 ] also reported similar findings with different synchronization protocols in postpartum anestrus crossbred cows. Further, the overall mean protein concentrations did not differ significantly between the two protocols at day 0 and day 9.…”

“…Bora et al . [ 33 ] observed higher plasma cholesterol concentrations on the day of induced estrus and on day 20 than day 10 or 0 of treated respondent postpartum anestrus crossbred cows. However, in earlier studies employing Ovsynch, Cosynch, PRID, etc., the plasma cholesterol levels were not influenced significantly between sampling days in anestrus cattle [ 4 , 32 , 34 ].…”

AimThis study aimed to evaluate the efficacy of Doublesynch and Estradoublesynch protocols on estrus induction, conception rates, plasma progesterone, protein, and cholesterol profile in anestrus Gir heifers.Materials and MethodsIn this study, 50 pubertal anestrus Gir heifers were selected from the field and farm conditions. The heifers were dewormed (injection ivermectin, 100 mg, s/c) and supplemented with minerals and vitamins (injection organic phosphorus 800 mg and injection Vitamin AD3E and Biotin 10 ml i/m) and multi-mineral bolus at 1 bolus daily for 7 days. The heifers were randomly divided into three groups: Doublesynch (n=20), Estradoublesynch (n=20), and control (n=10). The animals were monitored for estrus response, estrus interval, behavioral signs, and conception rates after induced/first, second, and third cycle post-treatment. Blood samples were obtained on day 0, day 9, day 12, and on day 12 post-artificial insemination (AI) for determination of plasma progesterone, protein, and cholesterol profile.ResultsThe estrus response rate between Doublesynch and Estradoublesynch protocols was similar between treated heifers (85% and 95%). The interval from the second prostaglandin F2α (PGF2α) injection to estrus induction did not differ between the groups (63.87±4.19 vs. 58.27±3.83 h). The conception rates following induced estrus (20% vs. 30%), at the second cycle (23.07% vs. 16.66%), at the third cycle (22.22% vs. 30.00%), and the overall conception rate (45% and 55%) within 27.89±5.75 and 26.45±5.48 days were the same across the treatment groups. The mean plasma progesterone concentrations were significantly (p<0.01) higher on day 9 (second PGF2α injection) and day 12 post-AI compared to day 0 (first PGF2α injection) and the day of fixed-timed artificial insemination. The concentrations were also significantly (p<0.05) higher in conceived than non-conceived heifers on day 9 of treatment and day 12 post-AI in both the protocols. The mean plasma cholesterol concentrations were significantly higher during peak follicular and luteal phases compared to the initial anestrus phase in both the protocols. The values were also higher in non-conceived than conceived animals in both the protocols. The plasma protein profile was not influenced by the sampling days or conceived and non-conceived status.ConclusionThe results showed that both Doublesynch and Estradoublesynch protocols resulted in similar estrus induction and conception rates with modulation of plasma progesterone and cholesterol profile in anestrus Gir heifers.

The aims of this study was to evaluate the effect of tonophosphan (TPH), as a phosphorous compound, on resumption of estrus and ovulatory activity of anestrous Egyptian buffalo heifers and anestrous post-partum buffalo cows, in relation with blood phosphorus level. Total of 24 anestrus animals with smooth ovaries and serum progesterone of <1 ng/ml up to 90 days postpartum (12 buffalo cows, weighing 470-530 kg, aging 5-7 years and between 3-4 parities. as well as 12 buffalo heifers, weighing 390-420 kg and 2.5-3 years old) were used in this study. In each of heifer and cow groups (n=12), animals were randomly divided into two subgroups (treated and control, 6 in each). Animals in treatment group (6 heifers and 6 cows) were injected twice at 7 day-interval with 4 ml/100 kg of TPH, while those in control group (6 heifers and 6 cows) were administrated with 4 ml distilled water/100 kg at the same time of TPH treatment. Estrous activity was detected twice daily to detect estrous signs. Blood samples were collected from all animals of each group on days 0, 3, 6, 10, 14, 18, 22, 26, 30, 34 and 38 of treatment. Results revealed that the estrus rate in treated animals was higher (P<0.05) in cows (83.33%) than in heifers (66.67%), while the control animals showed no estrous signs. Intensity, duration and interval from treatment to estrus were nearly similar in both heifers and cows. Concentration of serum P4 was higher (P<0.05) in cows than in heifers only on days 3 and 6 of treatment, while it was higher (P≥0.05) in cows than in heifers on other sampling days. Concentration of P4 was higher (P<0.05) in treated groups than in control on all sampling days, except during the 1 st and six days of treatment. Concentration of P4 was less than 1 ng/ml in control groups on all sampling treatment days, while P4 concentration level was ≥1 ng/ml after 10 days of treatment in treated groups. Concentration of Ca on most sampling days of treatment and P concentration on all sampling days were significantly (P<0.05-P<0.001) higher in heifers than in cows, while Ca:P ratio showed an opposite trend on all sampling days. In conclusion, Based on the foregoing results, twice tonophodphan injection of true anestrous buffalo heifers and cows at a week interval at a level of 4 ml/100 kg LBW has impact on resumption of estrous activity and achieving conception, being more effective for buffalo cows than for buffalo heifers.
