A preliminary study on milk yield, composition and economic profitability of alfalfa pellets and long ryegrass fibre (Kit N°10) in a total mixed ratio in lactating dairy cows

Abstract

This study was developed to improve the qualitative and quantitative performance of milk production of dairy cows. The aim of this work is to evaluate the impact of feeding Kit N°10 based on alfalfa pellets and long ryegrass fibre produced by “La Romana Farine srl” on the milk yield and milk composition in dairy cows. Kit N°10 was administered thrice daily to six multiparous Holstein–Friesian cows assigned to two treatments including control and staple feed Kit N°10. Feeding the Kit N°10 as basic ration improved animal performance by increasing significantly (p
