Comparative analysis of SNP candidates in disparate milk yielding river buffaloes using targeted sequencing [PDF]
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.

Genetic relationships between calving interval and body condition score conditional on milk yield [PDF]
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.

Dynamics of correlation coefficients of economic and productive characteristics depending on the age of cows [PDF]
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.

Body condition score and live-weight effects on milk production in Irish Holstein-Friesian dairy cows [PDF]
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.

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

Modelling temperature effects on milk production : a study on Holstein cows at a Japanese farm [PDF]
Milk yield and its composition vary according to individual cows as well as to a variety of different environment conditions, such as temperature.

COMPARISON OF DIFFERENT PROCEDURES FOR LACTATION LENGTH ADJUSTMENT OF MILK YIELD IN SAHIWAL CATTLE [PDF]
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
