Feed resource selection of Criollo goats artificially infected with Haemonchus contortus: nutritional wisdom and prophylactic self-medication

open access: yesAnimal, 2018
Previous cafeteria studies suggested that a moderate natural gastrointestinal nematode (GIN) infection did not modify the resource selection of adult Criollo goats towards tannin-rich plants compared with worm-free goats.

Optical selection rules of graphene nanoribbons

open access: yes, 2011
Optical selection rules for one-dimensional graphene nanoribbons are analytically studied and clarified based on the tight-binding model. A theoretical explanation, through analyzing the velocity matrix elements and the features of wavefunctions, can ...

New insights into genomic selection through population-based non-parametric prediction methods

open access: yesScientia Agricola
: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of ...

Reduction of traits for genetic evaluation of linear described traits in the Old Kladruber horse

open access: yesCzech Journal of Animal Science, 2012
The estimated genetic parameters were used for selection of important conformation traits and reduction in the number of the described characteristics. For reduction in the number of described traits from the original 36 to 24, the traits were selected ...

Genomic Prediction for Abortion in Lactating Holstein Dairy Cows

open access: yesAnimals, 2022
Abortion in dairy cattle causes great economic losses due to reduced animal health, increase in culling rates, reduction in calf production, and milk yield, among others. Although the etiology of abortions can be of various origins, previous research has
