Estimating test-day milk yields by modeling proportional daily yields: Going beyond linearity

open access: yesJournal of Dairy Science, 2023
In the United States, lactation milk yields are not measured directly but are calculated from the test-day milk yields. Still, test-day milk yields are estimated from partial yields obtained from single milkings. Various methods have been proposed to estimate test-day milk yields, primarily to deal with unequal milking intervals dating back to the ...

Once-daily milking effects in high-yielding Alpine dairy goats [PDF]

open access: yesJournal of Dairy Science, 2009
Two experiments were conducted to determine the milk loss of high-yielding Alpine goats resulting from once-daily milking (ODM) and its relationship to udder cisternal size. We investigated the effects of application of this management strategy on milk yield, composition, and technological parameters: lipolysis, fat globule size, and cheese yield. In a

Predicting bovine daily milk yield by leveraging genomic breeding values

open access: yesComputers and Electronics in Agriculture, 2023
The main goal of this work, conducted on a herd of 502 Holstein cows situated in Italy, is to propose a machine learning-based approach to forecast the individual bovine daily milk production by explicitly leveraging genotypic information. As part of our study, we also evaluated the importance in the prediction of genotypic and phenotypic variables ...

Estimation of Daily Milk Yields from AM/PM Milking Records

open access: yesJournal of Animal Science and Technology, 2013
Daily milk yields on test days were estimated using morning or afternoon partial milk yields collected by official agencies and the accuracy of the estimates was determined. Test-day data for milk yields consisted of 3,156,734 records of AM/PM partial milking measurements of 255,437 milking Holstein cows from 3,708 farms collected from December 2008 to

Prenatal maternal effects on body condition score, female fertility, and milk yield of dairy cows [PDF]

open access: yes, 2007
In this study, maternal effects were described as age of dam at first and second calving, first-lactation body condition score (BCS) of the dam during gestation, and milk yield of the dam.

BODY CONFORMATION WITH DAILY MILK YIELD RELATIONSHIP ON BUFFALOES

open access: yesJournal of Life Science and Applied Research, 2022
The study aimed to correlate milk yield with the body dimensions of buffaloes, during lactate season 2019, a total of 25 and 47 lactate buffaloes (Bubalus bubalis) were chosen randomly from Baghdad and AL-Muthanna province (270km south of Baghdad) respectively.

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

open access: yes, 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.

Technical note: Variation in daily milk yield calculations for dairy cows milked in an automatic milking system [PDF]

open access: yesJournal of Dairy Science, 2010
An accurate estimation of the daily milk yield of dairy cows milked in an automatic milking system is not obvious because of variations in milking intervals and frequencies. Daily harvested milk varies substantially, and developing a method to be used for estimating daily milk production is of great importance.

Impact of single nucleotide polymorphisms in leptin, leptin receptor, growth hormone receptor, and diacylglycerol acyltransferase (DGAT1) gene loci on milk production, feed, and body energy traits of UK dairy cows [PDF]

open access: yes, 2008
The impact of 9 single nucleotide polymorphisms (SNP) in the leptin (LEP), leptin receptor (LEPR), growth hormone receptor (GHR), and diacylglycerol acyltransferase (DGAT1) gene loci on daily milk production, feed intake, and feed conversion, and weekly ...
