Evaluation of an application for dynamic feeding of dairy cows [PDF]
, 2009 Dynamic feeding is an innovative application for concentrate feeding of dairy cows. Daily individual settings are derived from the actual individual milk yield response to concentrate intake.

Potentials to differentiate milk composition by different feeding strategies [PDF]
, 2009 To investigate the effect of the dietary intake of the cow on milk composition, bulk-tank milk was collected on 5 occasions from conventional (n = 15) and organic (n = 10) farms in Denmark and on 4 occasions from low-input nonorganic farms in the United ...

ESTIMATION OF DAILY AND LACTATION MILK YIELD FROM ALTERNATIVE MILK RECORDING SCHEME
Stočarstvo : Časopis za unapređenje stočarstva, 2008 Statistical methods were to developed and evaluated for the estimation of daily and 305-day lactation milk yield of dairy cattle from alternative milk recording scheme. Data included 7,815 individual test-day milk yield records collected according to the A4 milk recording method on 769 cows reared on 15 family farms.

Effects of Daily Exogenous Oxytocin on Lactation Milk Yield and Composition
Journal of Dairy Science, 1991 Eighty-four Holstein cows were used to determine effects of exogenous oxytocin on 305-d milk production and health. Cows were assigned at parturition by parity group to treatments: 1) oxytocin group, animals received an injection of 1 ml (20 IU) of oxytocin at each milking throughout lactation and 2) control group, animals received no injection ...

Kinetics of fat and protein secretion in dairy cattle, sheep, goats and buffaloes [PDF]
, 2003 The negative correlations of fat and protein concentrations and milk yield, existing in all ruminants dairy species (Oftedal, 1984; Mepham, 1987), reflect a deep mechanism regulating the respective kinetics of secretion of carrier (mainly lactose which ...

Estimation of daily milk yield of Nellore cows grazing tropical pastures
Tropical Animal Health and Production, 2018 Beef cows' milk yield is typically determined by measuring milk yield once daily and then doubling this value to estimate daily production. However, it is not known whether this is accurate. Thus, we aimed to determine the association between morning and afternoon milk yield in grazing Nellore cows. Eighty Nellore cows were used, with initial weight of

The Effect of Thermal Environment on Daily Milk Yield of Dairy Cows [PDF]
Macedonian Veterinary Review, 2016 Abstract The primary objective of this research was to evaluate the impact of environmental air temperatures on the milk production of dairy cows. Therefore, the experiment was carried out at the height of summer (from 15th of June to 15th of September) in three small family dairy farms and one commercial dairy farm.

Drying off the dairy cow [PDF]
, 2006 Most dairy cows generally have a non-lactating, “dry period” prior to parturition. As the milk production of dairy cows has increased dramatically during the last decades, cows managed conventionally with a 12 to 13 month-calving interval are dried off ...

Estimating Daily Yields of Cows Milked Three Times a Day
Journal of Dairy Science, 1986 Factors to estimate daily yield from one or two sampled milkings of cows milked three times a day were derived with data for 21 mo from seven Pennsylvania herds and data for 1 yr from five Utah herds. Accuracy of estimation increased with number of milkings weighed; standard deviation of error was nearly halved when information was included from two ...
