Study of The Effect of Using Some Feed Additives on Milk Production and Some of Its Components in Ruminants (Review Article)

This study aims to know the influence of consuming some feed additives in ruminant rations on milk production and some of its components. It was found that adding fenugreek seeds to the ration of Damascus goats had a significant effect in increasing milk production, while milk production increased and fat percentage decreased significantly in Awassi ewes, in local Sharabi cows, milk production and fat percentage increased significantly. Adding anise seeds to the ration of Holstein cows led to a significant increase in milk production and its components ( fat, protein and lactose percentage). Adding flax seeds to the ration of Holstein Friesian cows led to a significant increase in milk production while its components were not affected. Milk production and fat percentage increased significantly in Anglo-Nubian goats and Friesian cows when sesame seeds meal was added to the ration.
