Relationship between udder measurements and milk yield in Bergamasca ewes in Brazil
(Elsevier B.V., 2008-03-01)
The present work aimed to evaluate udders of Bergamasca ewes and their correlation with milk yield in a mix system of milk yield. Seventy-seven ewes were fed with balanced concentrate starting 20 days before lambing until ...
Genetic Parameter Estimates for Milk Yield and Lactation Length in Buffalo
(Int Buffalo Information Ctr, 2013-01-01)
The objective of this study was to estimate genetic parameters for milk yield at 244 days and lactation length in graded buffalo cows at the El Cangre Cattle Genetic Enterprise. Data were gathered from 2575 lactations, ...
Milking Machines on Chilean Dairy Farms and their Effects on Somatic Cell Count and Milk Yield: A Fied Study
(Instituto de Investigaciones Agropecuarias, INIA, 2006)
Pathogen effects on milk yield and composition in chronic subclinical mastitis in dairy cows
This study aimed to evaluate the effects of chronic subclinical mastitis (CSM) on milk production and component yields in dairy cows. A total of six herds located in the Midwest area of São Paulo State, Brazil were selected. ...
Polymorphism in the Beta Casein Gene and analysis of milk characteristicsin Gir and Guzera dairy cattle
Several human health problems have been related to the allergenic constitution of bovine milk due to the body's immune reaction to milk proteins. It is necessary find solutions to minimize the occurrence of such reactions, ...
Genetic parameter estimates for buffalo milk yield, milk quality and mozzarella production and Bayesian inference analysis of their relationships
Buffalo milk has excellent physical and chemical qualities as a consequence of the high percentage of constituents. This milk property is desirable for the dairy industry because it facilitates manufacture of mozzarella ...
Consistency of side choice in the milking parlour by holstein-friesian cows and its relationship with their reactivity and milk yield
Dairy cows often have to choose which of two sides to enter in the milking parlour. Some cows are very consistent in this choicė, and it is common to assume that when these cows are more disturbed are being milked in their ...
Effect of lactation length adjustment procedures on genetic parameter estimates for buffalo milk yield
(Sociedade Brasileira de Genética, 2011-01-01)
The objectives of this study were to estimate the genetic parameters for milk yield unadjusted and adjusted for days in milk and, subsequently, to assess the influence of adjusting for days in milk on sire rank. Complete ...
Effect of milk production on reproductive performance in dairy herds
(American Dairy Science Association, 2018-05-23)
The objective of the present study was to assess the relationship between individual cow milk yield and fertility, accounting for the contextual effect of the herd. A dataset including 657,968 lactations from 677 dairy ...
Factors affecting somatic cell counts and their relations with milk and milk constituent yield in buffaloes
Data concerning daily milk yield (MY), percentage of milk fat (%F), protein (%P), lactose (%LT), and total solids (%TS), and somatic cell counts (SCC) for a herd of 222 Murrah buffalo reared in the state of São Paulo, ...
