COMPARISON OF DIFFERENT PROCEDURES FOR LACTATION LENGTH ADJUSTMENT OF MILK YIELD IN SAHIWAL CATTLE [PDF]
Pakistan Veterinary Journal, 2004 The purpose of the present study was to compare three procedures for lactation length adjustment of milk yield. For this purpose, weekly milk yield records (n = 2039) of Sahiwal cows were used. Multiplicative adjustments using simple linear regression of

PREDICTION OF LACTATION YIELD FROM LAST-RECORD DAY AND AVERAGE DAILY YIELD IN NILI-RAVI BUFFALOES [PDF]
Pakistan Veterinary Journal, 2005 Different adjustment procedures were compared to determine if prediction of lactation milk yield using last record day information could be improved by using information on the average daily milk yield of the recorded lactation. Weekly milk yield records

Variation in carbon footprint of milk due to management differences between Swedish dairy farms [PDF]
, 2011 To identify mitigation options to reduce greenhouse gas (GHG) emissions from milk production (i.e. the carbon footprint (CF) of milk), this study examined the variation in GHG emissions among dairy farms using data from previous CF studies on Swedish ...

ENVIRONMENTAL FACTORS AFFECTING MILK YIELD AND LACTATION LENGTH IN SAHIWAL CATTLE [PDF]
Pakistan Veterinary Journal, 2004 Weekly milk yield records on 661 Sahiwal cows calving during 1990-2000 at the Livestock Experiment Station Bahadurnagar, Okara were used to study how milk yield and lactation length were affected by different environmental factors.

Covariance among milking frequency, milk yield, and milk composition from automatically milked cows
Journal of Dairy Science, 2011 Automatic milking systems allow cows voluntary access to milking and concentrates within set limits. This leads to large variation in milking intervals, both within and between cows, which further affects yield per milking and composition of milk. This study aimed to describe the degree to which differences in milking interval were attributable to ...

Agreement of Predicted 305-Day Milk Yields Relative to Actual 305-Day Milk Weight Yields [PDF]
Journal of Dairy Science, 2007 The objectives of this study were to compare the multiple trait prediction (MTP) model estimate of 305-d lactation yield with the 305-d daily milk yield data from on-farm automated meters and software and to examine the accuracy of electronic identification (ID).

Dietary supplementation of essential oils in dairy cows: evidence for stimulatory effects on nutrient absorption [PDF]
, 2019 Results of recent in vitro experiments suggest that essential oils (EO) may not only influence ruminal fermentation but also modulate the absorption of cations like Na+, Ca2+ and NH4+ across ruminal epithelia of cattle and sheep through direct ...
