Prevalence of Reproductive Disorders in Niali and Kantapara Block of Cuttack District, Odisha, India

Abstract

A survey was conducted to study the incidence of infertility in crossbred cows and distribution of repeat breeding crossbred animals in Niali and Kantapara block of Cuttack district, Odisha, India which revealed that, the incidence of reproductive problems were 45.18 per cent in cross bred cows and 25.47 per cent in heifers. Out of the total reproductive disorders, 36.89, 51.94 and 11.17 per cent of cases were recorded as postpartum anoestrus, repeat breeding and miscellaneous disorders, respectively in crossbred cows. In crossbred heifers the incidence of anestrus, repeat breeding, delayed maturity and miscellaneous disorders were recorded to be 38.21, 45.53, 7.32 and 8.94 per cent respectively. Incidence of infertility was higher in summer months (45.29%) than that in rainy (25.23%) or winter (29.48%) season. Incidence of repeat breeding in cows included in the study recorded to be highest in second calvers (40.19%) followed by first (21.50%) and third calvers (13.08%). Incidence of repeat breeding was higher in cows with average daily milk yield of 10-12 litres and above. The cows with 6-8 litres of average daily milk yield recorded to be the lowest (9.35%). Incidence rate for repeat breeding in animals was recorded to be highest (43.56%) in cows with a body condition score of 1-2. The overall distribution of repeat breeding in animals was found to be 30 and 70 per cent with sub active and functional ovaries. However cows with non-functional ovary did not reveal any repeat breeding problems.

Occurrence of repeat breeding in crossbred dairy cattle

“…Kutty and Ramachandran, (2003) also observed a high prevalence of RB (35 %) among crossbred cattle of Kerala. However, Harichandan et al (2018) reported the highest (51.94%) incidence of RB in dairy cows, in India. The incidence of RB varied with the season, number of calvings, body condition score, average days in milk etc.…”

WAKTU OVULASI DAN ANGKA KEBUNTINGAN PADA SAPI PERAH YANG MENGALAMI KAWIN BERULANG SETELAH PEMBERIAN GnRH, VITAMIN ADE DAN INFUSI IODIUM POVIDON

“…Repeat breeding (kawin berulang) pada sapi perah merupakan salah satu gangguan reproduksi yang menyebabkan kerugian ekonomi cukup besar bagi peternak karena jumlah inseminasi yang lebih banyak, jarak beranak yang panjang, dan penurunan produksi. Sapi yang mengalami kawin berulang (repeat breeding) adalah sapi betina yang mempunyai siklus dan periode estrus normal, sudah dikawinkan tiga kali atau lebih dengan pejantan fertil atau diinseminasi buatan dengan semen pejantan fertil tetapi tetap belum bunting (Robert, 1986) Kejadian kawin berulang pada sapi persilangan sekitar 36% (Azeez et al, 2017), 25,96% (Arun et al, 2020), pada sapi perah di Daerah Istimewa Yogyakarta 29,4 % (Prihatno et al, 2013), sapi perah di India tertinggi 51,94% (Harichandan et al, 2018), dan 23,60% (Aruna et al, 2021). Penyebab dasar kawin berulang adalah kegagalan fertilisasi dan kematian embrio dini.…”
