Hello everyone, how is everything going on there? I hope you’re doing well. Currently, I'm gonna conduct a study about the role of breed, feed, health, and environment improvement on livestock productivity. However, I have a doubt which one is best to contribute to livestock productivity. I want to know the one that should be prioritized, and/or at least contribute in a high percentage. Nowadays, the livestock sector is being claimed as a driver of climate change and food security. Indeed, to enhance food security, it would be better to mitigate climate change while increasing livestock productivity. I believe that breed, feed, health, and environment should be improved before the commencement of animal production. Here, my question is as follows:
Which one of the following is best contributing to livestock productivity?
A. BREED B. FEED C. HEALTH D. ENVIRONMENT
NB: I highly appreciate and encourage you to provide your description with the potential evidence.
With kindest regards!
