(Medwell Online, 2009)
The aim of this study, was to estimate genetic and phenotypic parameters for birth weight and to determine the survival rate of calves of Holstein Friesian cattle reared organically. Aborting rate, still born rate and the ...
Performance and health of dairy calves fed limited amounts of acidified milk replacer
(South African Journal of Animal Sciences, 2006)
To compare growth performance of Brown Swiss calves fed acidified milk replacer (AMR) at 8% of birth weight, 20 newborn calves were reared under a new calf-feeding programme. Body weights, total weight gains and gains in ...

The purpose of the study was to determine the effects of average daily gain and age at first calving on the reproductive and milk production traits of Brown Swiss (BS) ad Holstein Friesian (HF) cattle. For this purpose, ...
The Effect of Concentrate Feeding Levels on the Postweanining Performance of Holstein Friesian Calves
(Turk J Vet Anim Sci, 2002)
The influences of different levels of concentrate on the growth characteristics of Holstein Friesian calves reared under an original calf-rearing program were investigated in this study. Forty-one new-born calves (20 male ...
Genetic and Environmental of Milk Ability Traits in Holstein Friesian Cows
