The Efficacy of Bovine Pituitary Extract for Treating Ovarian Hypofunction Cases in Bali Cattle

Abstract

Ovarian hypofunction is marked by the absence of a follicle or corpus luteum, which leads to a smooth ovarian surface during rectal examination. Furthermore, cattle affected by this disease experience an extended period of anestrus, where they do not display signs of estrus. This condition can be treated by administering gonadotropin hormones. One reliable source of these hormones is the bovine pituitary, which contains follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Therefore, this study aims to demonstrate the efficacy of bovine pituitary extract as a source of FSH in enhancing follicle development and inducing estrus response in cattle with ovarian hypofunction. The study was conducted experimentally using a completely randomized design with two groups: a control group and a treatment group. In the control group, cattle were injected with a placebo (Physiological NaCl) of 1.5mL intramuscularly in two repetitions. Meanwhile, 1.5mL of bovine pituitary extract was injected into cattle intramuscularly in the treatment group.
