The reason why cattle eat dung is probably that they lack certain elements in their bodies, and their daily feed cannot be supplied, so they need to be supplemented by other "foods". This is called pica.
If obvious pica symptoms are found, we can make up for them from the following four aspects and improve the feeding management measures.
(1) Feed enough green hay.
(2) Reasonable collocation of concentrated feed, the proportion of corn flour, cake and wheat bran can be 50%, 30% and 20% if possible.
③ salt supplement. Every adult cow is supplemented with 50-100g of salt every day, which is put in a basin or cow trough for cows to lick freely, or mixed with feed for cows to eat.
④ Every adult cow should be supplemented with bone meal 100- 150g every day, or the bones of pigs, cows and sheep can be dried and crushed and mixed in the feed to feed the cows.
You can also buy licking bricks and hang them in the cowshed for the cowshed to lick trace elements and minerals.
