Recent prediction tools for estimation of first lactation 305 days milk yield using monthly test days for genetic evaluation in crossbred cattle

Indian Journal of Animal Sciences, 2022
First lactation 305 days milk yield (FL305DMY) of progenies is an important criteria for selection of sires. In field progeny testing programme, prediction of FL305DMY based on test day records will reduce the cost of recording.

Determining Point of Economic Cattle Milk Production through Machine Learning and Evolutionary Algorithm for Enhancing Food Security

Journal of Food Quality, Volume 2023, Issue 1, 2023., 2023
Artificial neural networks (ANNs) in conjugation with genetic algorithms (GAs) have been demonstrated to be an effective tool for system modelling and optimization in a variety of applications. The current communique is about assessing the capacity of ANN to predict investment on cattle till age at first calving (AFC) and milk production based on the ...
