Genetic parameters between somatic cell score and production traits for Holstein cattle in Southern Brazil

open access: yesRevista Colombiana de Ciencias Pecuarias, 2020
Background: Somatic cell score is an important parameter to predict milk quality and health of cows. However, in countries like Brazil, this trait is still not selected on a large scale, and no genetic parameters are reported in the literature. Objective:

Body Condition Score and Milk Production on Conception Rate of Cows under a Small-Scale Dairy System

open access: yesAnimals, 2019
Management and production characteristics impact conception rate to first service (CR1S) in small-scale dairy farms, but the impact of body condition score (BCS) and milk production levels on cows’ fertility is unknown.

Relaxation Dynamics of the Holstein Polaron [PDF]

open access: yesPhysical Review Letters, 2012
Keeping the full quantum nature of the problem we compute the relaxation time of the Holstein polaron after it was driven far from the equilibrium by a strong oscillatory pulse. Just after the pulse the polaron's kinetic energy increases and subsequently exhibits relaxation type decrease with simultaneous emission of phonons.

Bio-economical model application in cattle breeding

open access: yesActa Agriculturae Slovenica, 2005
Dairy production systems are complex and cannot be described by a single profit function. In a bio-economical model, relevant biological and economical aspects of the production system are described as a system of equations.

Effect of fattening period on growth performance, carcass characteristics, and economic traits of Holstein steers

open access: yesJournal of Animal Science and Technology, 2021
This study was conducted to investigate the effect of different fattening periods on the growth performance, carcass characteristics, and economic traits of Holstein steers. Sixty Holstein steers (8.0 ± 0.28 months

Optical Conductivity of the Holstein Polaron [PDF]

open access: yesPhysical Review Letters, 2011
The Momentum Average approximation is used to derive a new kind of non-perturbational analytical expression for the optical conductivity (OC) of a Holstein polaron at zero temperature. This provides insight into the shape of the OC, by linking it to the structure of the polaron's phonon cloud.
