Estimation of genetic parameters for milk traits in Romanian local sheep breed [PDF]
Revista Mvz Cordoba, 2014 Objective. Estimate the genetic parameters for milk traits in a Romanian local sheep population Teleorman Black Head. Material and methods. Records of 262 sheep belonging to 17 rams and 139 ewes were used in the study.

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

Associations between sole ulcer, white line disease and digital dermatitis and the milk yield of 1824 dairy cows on 30 dairy cow farms in England and Wales from February 2003–November 2004 [PDF]
, 2008 The milk yields of 1824 cows were used to investigate the effect of lesion-specific causes of lameness, based on farmer treatment and diagnosis of lame cows, on milk yield.

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.

Nature, 1953 IN the early stages the growth of the lamb is largely dependent on the milk yield of its dam. In hill sheep, where the environment constitutes the limiting factor to production, a study of the milking capacity of the ewe would seem to be of special interest, as it forms a large part of the lamb's environment at a most important period of growth.

Genetic relationships between calving interval and body condition score conditional on milk yield [PDF]
, 2002 Body condition score (BCS) is a useful tool in assessing the energy status of dairy cattle. Previous research has shown that it is heritable and genetically correlated to reproductive performance.

Estimation of milk yield in the rat [PDF]
Laboratory Animals, 1970 The biases inherent in the use of the growth curves of the litter and of milking devices to estimate milk yield in the rat are discussed. A method is described in which the pups are separated from their dams for a period of hours and are then allowed to suck for about 60 minutes.

Body condition score and live-weight effects on milk production in Irish Holstein-Friesian dairy cows [PDF]
, 2007 peer-reviewedThe objective of the present study was to quantify the relationships among body condition score (BCS; scale 1 to 5), live weight (WT) and milk production in Irish Holstein-Friesian spring calving dairy cows.

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.
