“…However, most of the previous studies (Sathiamoorthy and Kathirchelvan, 2010;Murugavel et al, 2010b) have shown that majority of the cows have exhibited intense estrus following CIDR treatment. Low percentage of cows showing intense estrus when compared to the previous studies could be due to low concentration of estrogen hormone in plasma to express estrus behaviour (Devipriya et al, 2020), difference in body condition and nutritional status of the animal (Butler, 2003).…”

The present study was conducted to evaluate the influence of blood glucose, total protein and haemoglobin at the time of induced estrus on conception rate in 30 postpartum anestrus crossbred dairy cows. The cows were treated with progesterone intravaginal (CIDR) based estrus induction protocol with double fixed timed inseminations at 12 and 24 h after injection of last GnRH. estrus induction response was 100% with majority of the cows (80%) showed intermediate intensity of estrus. On the day of first AI, blood was collected from all the animals for the estimation of glucose, total protein and haemoglobin. The mean time to onset of estrus from the time of removal of CIDR was 44.85 ± 7.23 h. The overall conception rate in the present study was 30 % (9/30). In the present study, the mean values of glucose, total protein and haemoglobin at the time of estrus were 43.81 ± 1.14 mg/dl, 7.78 ± 0.24 g/dl and 8.68 ± 0.22 g/dl respectively. The mean glucose, total protein and haemoglobin levels in the anestrus cows which were included in the study are lower than the normal range. There is no significant different in the biochemical parameters among the cows showing weak, intermediate and intense intensity of estrus. Similarly, there is no significant difference in the biochemical parameters between the cows that conceived and cows not has not conceived. The findings in the present study clearly indicates that poor nutritional status may be the cause for the anestrus condition of the animal under field conditions.

“…Hence unobserved estrus and silent estrus are more common in Changes in Mineral Profiles in Progesterone-based Estrus Induction Protocols and their Relationship with the Phases of Estrous..... these breeds. This issue necessitated the use of estrus induction protocols (Naikoo et al, 2016;Devipriya et al, 2020;Periyannan et al, 2021;Manokaran et al, 2023) to achieve a favourable conception rate in indigenous breeds of cattle. Allan et al (1993) stated that pregnancy rates were increased in cows that were supplemented with trace elements with Vitamin bolus.…”

Background: For the successful reproduction in Kangayam cows, adequate nutrition containing sufficient quantum of minerals is necessary. Minerals are important cofactors in majority of the metabolic and immune reactions and hormone synthesis that could affect reproduction. Present study was planned to analyse whether mineral levels change in different treatment days following estrus induction and corresponding changes in stages of the estrous cycle. Methods: Non pregnant, pluriparous Kangayam cow (n=70) were allotted to control and different treatment protocols (each consist of 10 cows) based on the transdermal (PNC based groups) and transvaginal application of progesterone (CIDR based group) with a shot of PGF2α one day preceding the day of progesterone removal. Ovulation was induced either using estradiol benzoate or buserelin acetate. Mineral profiles were analysed on the day of progesterone application (APP), removal (REM), AI and 10 days post insemination (10 DPAI). Result: It indicated that changes in the mineral levels between the treatment days especially on the day of AI and 10DAPAI could be correlated with the corresponding follicle and luteal phases and it could be concluded that there were significant changes especially in selenium, manganese, zinc and copper levels between the treatment days in each group which could be extrapolated to have specific roles in stages of estrous cycle. Among these minerals copper levels could be correlated to affect the steroid concentration by altering its metabolism thereby its clearance in Bos indicus breed ie Kangayam breed of Tamil Nadu.
