Estimates of correction factors for lactation length and genetic parameters for milk yield in buffaloes

Milk yield and milk components (percentage of fat and protein) presented sufficient genetic variation to provide genetic gains in selection

Data was available on daily average milk yield (AMY), total lactation milk yield (TMY), last milk yield before drying of (LMY) and milk yield corrected for 305 days lactation

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

ABSTRACT - The major objective of this study was to estimate heritability and genetic correlations between milk yield (MY) and calving interval (CI) and lactation length (LL) in

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

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
