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.

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.

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.

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.

Animal, 2014 The aim of this study was to investigate the effect of including milk yield data in the international genetic evaluation of female fertility traits to reduce or eliminate a possible bias because of across-country selection for milk yield.

Comparison of 2 types of milk flow meters for detecting bimodality in dairy cows
Journal of Dairy Science, 2023 : The primary objective of this observational study was to investigate whether incremental milk flow rates (in the 0–15 s, 15–30 s, 30–60 s, and 60–120 s intervals) from electronic on-farm milk flow meters can be used to detect bimodal milk flow curves ...

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

PREDICTION OF LACTATION YIELD FROM LAST-RECORD DAY AND AVERAGE DAILY YIELD IN NILI-RAVI BUFFALOES [PDF]
Pakistan Veterinary Journal, 2005 Different adjustment procedures were compared to determine if prediction of lactation milk yield using last record day information could be improved by using information on the average daily milk yield of the recorded lactation. Weekly milk yield records

ENVIRONMENTAL FACTORS AFFECTING MILK YIELD AND LACTATION LENGTH IN SAHIWAL CATTLE [PDF]
Pakistan Veterinary Journal, 2004 Weekly milk yield records on 661 Sahiwal cows calving during 1990-2000 at the Livestock Experiment Station Bahadurnagar, Okara were used to study how milk yield and lactation length were affected by different environmental factors.
