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

Twenty-four Holstein cows (five months in milk on average) were grouped in blocks of three cows, according to parity and milk production, in a multiple 3 × 3 Latin square design,

The objective of this study was to estimate the covariance components and genetic parameters for test- day milk, fat and protein yields of primiparous Holstein cows, using

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

Se observó en los casos negativos a la prueba de alcohol una alta correlación entre el contenido de materia seca y mayor concentración de fósforo lácteo, además de una alta

The effects of farm, parity (PO) and month of parturition on milk production, percentage of fat and protein, somatic cell count (SCC), and milk urea nitrogen (MUN) concentration

It is concluded that extension model used in the present work is reliable for extending the lactation curve in Holstein cows, and the increase in milk yield in response to the

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
