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.

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.

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.

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
