Effect of Silage Volatile Fatty Acid Content on Milk and Meat Yield and Quality

Silage quality is closely related to the maturation status of the forage crops at harvest. In ruminant animals, silage consumption of dried forage is less than that of fresh one of the same material. Silage is the basic feed source for beef and dairy cattle production. Quality of forage, thus, is one of the most important factors affecting meat and milk quality and quantity in the animal sector. The production of high quality milk is necessary for further processing of raw milk to produce high quality food. Moreover, the quality of forage not only affects the general composition and character of meat and milk, but also the individual building blocks of products. It’s clear that producing roughage based on high quality silage is of high importance in terms of both the breeder and national economy now and in the near future. Indeed, the proportion of concentrates in total mixed ration is influenced by the quality of silages and increasing concentrates in total mixed ration enhances not only milk yield, but change milk composition also. Silage contains nutrients and VFAs in appropriate quantities and is similar to VFAs, which are produced in the ruminant's rumen and meet 60% of the energy needs. In this study, the silage VFAs have been seen to have a positive effect on milk quality and quantity as well as the quantity and composition meat and it has been determined that the presence of quality silage in the ration has led to lowering the concentrate feed ratio
