Matricaria chamomilla CH12 decreases handling stress in Nelore calves

Matricaria chamomilla CH12 is a phytotherapeutic or homeopathic product, which has been used to reduce stress. Here, we examined its effect on preventing handling stress in bovines. Sixty Nelore calves were randomly distributed into two equal groups. One group was administered Matricaria chamomilla CH12 in diet and the other the 'control' was not. Animals in both groups were maintained unstress...

Alternative parameterizations of relatedness in whole genome association analysis of pre-weaning traits of Nelore-Angus calves

Gestation length, birth weight, and weaning weight of F2 Nelore-Angus calves (n = 737) with designed extensive full-sibling and half-sibling relatedness were evaluated for association with 34,957 SNP markers. In analyses of birth weight, random relatedness was modeled three ways: 1) none, 2) random animal, pedigree-based relationship matrix, or 3) random animal, genomic relationship matrix. Det...

Amniotic fluid cytology at parturition from Nelore calves conceived by artificial insemination, embryo transfer, or in vitro production

The aim of the present study was to describe the differences in the cytological pattern of amniotic fluid at the moment of parturition, comparing the data from Nelore calves conceived by in vitro production, conventional embryo transfer, or artificial insemination. Sixty Nelore cows were divided in three groups as follows: Group 1, 20 pregnant cows carrying Nelore calves conceived by in vitro p...

The effects of long term handling stress on thyroid function in male rats

Inappropriate responsiveness of the stress system may cause numerous alterations in endocrine, metabolic and autonomic systems. Many studies have been carried out on the effects of acute stress on thyroid function but the effects of chronic stress have not been fully investigated. The purpose of this study is to evaluate the effects of long term handling stress on thyroid function. Study was pe...
