Summary

Farmers can reduce difficult births (dystocia) in Grati cattle by using local bulls, especially for first-time mothers. Using exotic bulls with artificial insemination increases abnormal births and calf weight.

Area of Science:

Animal Science
Veterinary Medicine
Reproductive Biology

Background:

Dystocia and birth weight are critical factors influencing calf survival and herd productivity in cattle.
Grati cattle, a local breed in East Java, face challenges that may impact calving ease and calf development.

Purpose of the Study:

To identify key factors influencing dystocia and birth weight in Grati cattle.
To provide evidence-based recommendations for improving calving outcomes in the Pujon district.

Main Methods:

Retrospective analysis of 268 parturition records from Grati cattle in Pujon, East Java.
Data collected included birth weight, dystocia score, village, season, parity, sex, service type (artificial insemination [AI] vs. natural service), and dam age and weight.
Statistical analysis was performed to determine the significance of various factors on birth weight and dystocia.

Main Results:

Dam weight and village significantly affected birth weight, but not dystocia.
Parity was a significant factor influencing dystocia scores.
Artificial insemination (AI) with exotic bulls was associated with a higher incidence of abnormal births.
Calves born from abnormal births were, on average, over 3 kg heavier than those from normal births.
First-parity births combined with AI using exotic bulls showed a particularly high incidence of dystocia.

Conclusions:

Farmers in Pujon can mitigate dystocia in heifers by exclusively using local bulls.
Management strategies should consider parity and service type to reduce calving difficulties in Grati cattle.
