Hello dear @etemitee, thank you for your valuable comment, it is a question that covers several aspects, but I will try to be as precise as possible.
Going into the topic, it is necessary to mention that livestock production is influenced by many aspects of milk production, taking into account that we are in a natural ecosystem, the climatic factor is one of the elements that can influence production; because for example, in tropical areas if the animals are in the paddocks without any shade from the trees, this could generate a heat stress that influences production.
Genetics and nutrition is another important factor animals of a good genetics need an equated and quality nutrition, therefore, it must be ensured that the forage that is being supplied to the animals is of quality, for that efficient management of pastures must be implemented.
On the other hand, animal health, logically also influences, that's why milking should be done with the best possible hygiene, one of the diseases could be mastitis which consists of inflammation of the udder due to infections.
There are many factors that can influence why in the agricultural sector it is important to keep records of the components of the system, with that we can detect any anomaly that is related to the decrease in production.
So long, have a great week.
Not so long…. I appreciate you taking time to help me understand.
Thank you. Have a lovely week too
