Influence of environmental factors and parity on milk yield dynamics in barn-housed dairy cattle
Journal of Dairy Science, 2022 : We investigated the effects of environmental factors on average daily milk yield and day-to-day variation in milk yield of barn-housed Scottish dairy cows milked with an automated milking system.

Decreased milk yield is associated with delayed milk ejection [PDF]
Journal of Dairy Science, 2019 To determine whether individual cow milking vacuum (within the short milk tube and the liner mouthpiece) could be substituted for milk flow technology to identify delayed (bimodal) milk ejection, and the possible relationship between bimodal milk flow and milk yield, we recorded milking data from 663 Holstein cows on a 3,600-cow Michigan dairy that ...

Genetic analysis of first dry period and lifetime performance in Hariana cattle
Indian Journal of Animal Sciences, 2022 The present study was aimed to study lifetime milk production of Hariana cattle in organized farms. The nongenetic factors such as period of calving/birth, season of calving/birth, AFC age group and farms on these traits were studied by least-squares ...

Age at first calving and lifetime performance of Hariana cattle at organized farms
Indian Journal of Animal Sciences, 2022 The present investigation was undertaken to access age at first calving, actual lifetime milk yield per day of productive life, actual lifetime milk yield per day of herd life and actual lifetime milk yield per day of total life. The non-genetic factors

Dynamics of correlation coefficients of economic and productive characteristics depending on the age of cows [PDF]
E3S Web of Conferences, 2021 In 2002, a new Ural type of black-and-white breed was officially registered. Animals of this type have high productivity indicators, but at the same time there is a decrease in the productive longevity of the breeding stock.

Comparative analysis of SNP candidates in disparate milk yielding river buffaloes using targeted sequencing [PDF]
PeerJ, 2016 River buffalo (Bubalus bubalis) milk plays an important role in economy and nutritious diet in several developing countries. However, reliable milk-yield genomic markers and their functional insights remain unexposed.
