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

Phenotypic effects of calving ease on the subsequent fertility and milk production of dam and calf in UK Holstein-Friesian heifers [PDF]

, 2011
The effect of calving ease on the fertility and production performance of both dam and calf was studied in approximately 50,000 and 10,000 UK Holstein-Friesian heifers and heifer calves, respectively. The first objective of this study was to estimate the

Accuracy of predicting milk yield from alternative milk recording schemes [PDF]

, 2005
peer-reviewedThe effect of reducing the frequency of official milk recording and the number of recorded samples per test-day on the accuracy of predicting daily yield and cumulative 305-day yield was investigated.

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.

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 ...

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).

The effect of milking frequency on milk yield and milk composition in ewes

Czech Journal of Animal Science, 2020
Milking frequency is the main factor regulating milk yield and milk quality if feeding, welfare, health, and environmental conditions are adequate. Milk yield and composition are substantially influenced by breed, and consequently the breed has an impact

The chemical composition and technological properties of milk obtained from the morning and evening milking

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Milk yield varies during lactation, following what is termed a lactation curve. ŽIŽLAVSKÝ and MIKŠÍK (1988) recorded changes in milk yield within a day, too. TEPLÝ et al. (1979) a KOUŘIMSKÁ et al. (2007) published variation within a day ± 1.10 kg in milk
