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 ...

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.

Evaluation of Milk Yield and Milk Composition of Honamlı Goats
Journal of the Hellenic Veterinary Medical Society, 2021 The aim of this study was to determine the milk yield and milk composition (total solids, fat, protein and lactose), freezing point depressionand somatic cell counts of Honamlı goat during second lactationin Turkey. The animal material of the study consisted of a total of 30 goat. Total milk yield was detected by using Fleischmann’s method.
