Histology and morphometry of the testes of adult domestic cats (Felis catus)
(Journal of Feline Medicine and Surgery, 2012-02-01) [Artigo]
Testicles of 30 mongrel cats were analyzed histologically and morphometrically, divided into three groups: G1 (1-2 years old), G2 (over 2 and up to 4 years old) and G3 (over 4 and up to 6 years old). After orchiectomy and ...
Evaluation of ovarian follicular production in ewes submitted to follicular aspirations at a one week interval: pilot study
(Reproduction In Domestic Ruminants Vii, 2010-01-01) [Resumo]
Demecolcine Effects on Microtubule Kinetics and on Chemically Assisted Enucleation of Bovine Oocytes
(Cloning and Stem Cells, 2009-03-01) [Artigo]
This study aimed to evaluate the effect of demecolcine, a microtubule-depolymerizing agent, on microtubule kinetics; to determine the best concentration of demecolcine as a chemically assisted enucleation agent in metaphase ...
The interval between the emergence of pharmacologically synchronized ovarian follicular waves and ovum pickup does not significantly affect in vitro embryo production in Bos indicus, Bos taurus, and Bubalus bubalis
(Theriogenology, 2015-02-01) [Artigo]
The aim of the present study was to determine the optimal phase of the follicular wave to perform ovum pickup (OPU) for in vitro embryo production (IVEP) in various genetic groups. For this purpose, 27 heifers-nine Bos ...
Monitoring ovarian cycles and pregnancy in brown brocket deer (Mazama gouazoubira) by measurement of fecal progesterone metabolites
(Theriogenology, 2006-01-20) [Artigo]
In the present study, pregnancy and the estrous cycle were monitored in captive brown brocket deer (Mazama gouazoubira) by measuring fecal progestagens with a commercial enzyme immunoassay (EIA), along with behavioral data. ...
Seasonal changes in fecal testosterone concentrations and their relationship to the reproductive behavior, antler cycle and grouping patterns in free-ranging male Pampas deer (Ozotoceros bezoarticus bezoarticus)
(Theriogenology, 2005-05-01) [Artigo]
The purpose of this study was to validate noninvasive endocrine monitoring techniques for Pampas deer and to evaluate seasonal changes in testicular steroidogenic activity and their correlation to reproductive behavior, ...
Isolation of Campylobacter jejuni from viscera and bile secretion of broiler chickens with diarrhea
(Revista de Microbiologia, 1997-04-01) [Artigo]
Since chickens are important reservoirs of Campylobacter jejuni and their meat is the most frequent route of transmission for human campylobacteriosis, the purpouse of the present study was to investigate the presence of ...
Effect of follicular fluid supplementation during in vitro maturation on total cell number in bovine blastocysts produced in vitro
(Revista Brasileira de Zootecnia = Brazilian Journal of Animal Science, 2014-03-01) [Artigo]
This study evaluated the influence of follicular fluid (FF) added to the maturation medium on the quality of bovine embryos produced in vitro. In the first experiment, oocytes were matured in media containing five different ...
Reproductive tract development and puberty in two lines of Nellore heifers selected for postweaning weight
(Theriogenology, 2013-07-01) [Artigo]
The objective was to evaluate reproductive tract development (ovary and uterus) and onset of puberty in two lines of Nellore heifers (Bos indicus) selected for postweaning weight. A total of 123 heifers, including 46 from ...
Analysis of follicular events in owl monkeys (Aotus azarai infulatus) using B-mode and Doppler ultrasound
(Theriogenology, 2013-07-15) [Artigo]
Ultrasound (B-mode) was used to analyze follicular events in 12 trained female owl monkeys (Aotus azarai infulatus). The animals were examined every 48 hours for over 90days to measure and map follicular growth in both ...
