abstract
An animal's health and welfare are enhanced by optimal young stock rearing, which also makes the herd more sustainable. Producers require knowledge into their kid's rearing outcomes, ideally based on key indications, in order to assess the rearing process. While mortality is thought to be a valuable metric for evaluating the general well-being and health of animals, less is known about its occurrence and the factors that affect it in the dairy industry. How and when producers record mortality after birth may present additional challenges to calculating the risks of kid mortality. The current study's findings indicate that by taking action to regulate environmental and animal-related factors, mortality losses may be reduced. Since the maximum birthweight has not yet been attained, there is still room to increase birthweight by improved nutrition for the mother, which will lower the infant death rate. The highest observed mortality rates were attributed to respiratory diseases (MTR-I=1.77%, MTR-II=7.29%), then blood diseases (MTR-I=0.85%, MTR-II=3.52%), other group diseases (MTR-I=0.41%, MTR-II=1.69%), digestive system diseases (MTR-I=0.85%, MTR-II=3.52%), and tetanus (MTR-I=0.32%, MTR-II=1.30%). Another way to reduce mortality would be to determine the dam's threshold weight at kidding in relation to child mortality. External validation can be carried out on separate datasets of Marwari sheep from different regions to ensure the model's generalizability.
