Correlation between body condition score and hormone level of Bali cattle with postpartum anestrus

Abstract

Body Condition Score (BCS) is a simpler and more practical method to evaluate the body’s energy and fat reserves in cows. Nutrition play a direct role both in the hypothalamus by synthesizing and releasing GnRH, as well as on the anterior pituitary by controlling the synthesis and release of Leptin, FSH, LH and Estrogen. The purpose of this study was to determine the relationship between the body condition score with the activation of hormones in the hypothalamic–pituitary–gonadal axis on Bali cattle that experienced postpartum anestrus. This research was an observational analytic study with Cross-Sectional Study design. The samples used were Bali cattle that have given birth and have not shown estrus for more than three months. BCS assessment method is qualitatively conducted through visual and tactile techniques. Measurements of Leptin, FSH, LH and estrogen hormone levels were performed using the ELISA Double Antibody Sandwich method. The results showed a correlation between body condition score to hormone level i.e. Leptin level of 0.861; LH level of 0.960; FSH level of 0.799; and Estrogen level of 0.761. These data demonstrated that BCS significantly affects Leptin hormone concentrations. It takes Leptin with a certain concentration to trigger the release of LH in follicle maturation and ovulation, thus achieving a threshold that causes the activation of the hypothalamic–pituitary–gonadal axis.

Genetic Monomorphism of Luteinizing Hormone Receptor (lhr) Gene by Restriction ‎Fragment Length Polymorphism and Expression of LH in Egyptian Buffaloes

“…Luteinizing hormone plays a substantial role in contributing ovarian inactivity in buffaloes (Razdan et al 1981).In this study, the average concentrations of serum LH hormone samples were recorded in the 1 st group (ovarian inactivity) (1.98 ± 0.088), 2 nd group (silent heat) (2.17 ± 0.057) and 3 rd group (control) (2.2 ± 0.068). These results were in contact with Agustina (2019) and Taher et al (2020) who reported the reduction in both FSH and LH in inactive ovaries. Other related studies Janakiraman et al (1980); Aboul-Ela and Barkawi (1988); Singh and Chaudhry (1992) recorded that secretion was lower during summer compared to winter.…”

Administration of concentrated diet to overcome cases of delayed puberty in bali cattle

“…Puberty in animals does not indicate a standard and perfect reproductive capacity. The appearance of puberty is marked by changes in the external genitalia during estrus, such as redness of the vaginal mucosa, discharge from the vagina, and swelling of the vulva (Laksmi et al, 2019). In the form of concentrate, supplementary feedings such as calcium, phosphorus, crude protein, fat, and fiber show a faster estrus emergence time than others without the treatment.…”

“…This explains why a close relationship exists between body condition score and reproductive hormone level in Bali cattle with postpartum anestrus. BCS 3 tends to produce more estrus in a minimal amount of time, while BCS 2 cattle can experience delays in the emergence due to ovarian hypofunction (Laksmi et al, 2019).…”

Reproduction Performance as a Basis for Selecting Female Balinese Cattle in Traditional Breeding in East Halmahera Regency

“…It takes longer compared to the results of previous studies ranging from 28-43 days. It was stated (Laksmi et al, 2019) that the average time of first and second ovulation of primiparous cattle is 27.67 and 47.67 days postpartum, while the average time of first and second ovulation of pluriparous cattle is 28.33 and 43.33 days postpartum. This showed a correlation between body condition scores and hormone levels, namely Leptin levels of 0.861; LH level of 0.960; FSH level of 0.799; and Estrogen level of 0.761 (Laksmi et al, 2019).…”
