The objective of this study was to model MUN and lactose levels in Holstein cows and their relationship with days in milk (DIM), milk yield, milk fat, milk protein, and

Two hundred and seventeen records on milk production per lactation period (MY), milk production up to 305 days of lactation (MY305) and length of lactation period (LL) of 82

The milk yield and fat-corrected milk yield were lower (P<0.05) for those animals consuming corn steep liquor than for those fed soybean meal (Table 6), likely due

Genotype BB of the kappa-casein gene had more influence on the monthly milk yield, 305-days milk yield, monthly solids-not-fat (SNF) yield, and monthly protein yield, in the

Therefore, the aim of this study was to estimate heritability as well as genetic and environmental correlations between 305-day milk yield (Milk305), milk yield in the first

Protein content was positively correlated with fat, total solids, SCS, and stage of lactation, and negatively correlated with milk yield, lactose, and lactation number.. The

The highest lactation milk yield was observed in imported and farm born Holstein Friesian cows calved during autumn, while in imported Jersey cows maximum lactation milk yield was
