Different sperm selection methods used for ovine in vitro embryo production. Repository: BDPA Publication year: 2013
Effect of hydrogen peroxide on thawed ovine sperm motility. Oxidative stress, resulting from excessive levels of ROS in semen, has a negative impact on functional parameters and sperm fertility. In this study we examined the influence of the oxidative stress i... ... Repository: BDPA Publication year: 2014
Ovine B-globin polymorphisms and resistance to haemonchosis in different breeds. The selection of naturally resistant sheep breeds to gastrointestinal nematodes (GIN) can be a tool for controlling infections caused by Haemonchus contortus, responsible for haemonchosis and resistan... ... Repository: BDPA Publication year: 2023
Epidemiology of ovine toxoplasmosis and neosporosis in rams from Rio Grande do Sul, Brazil. Although the State of Rio Grande do Sul is one of the principal sheep rearing regions in Brazil, the prevalence of Toxoplasma gondii and Neospora caninum is unknown in rams. The objective of this stud... ... Repository: BDPA Publication year: 2018
Effect of estrus synchronization and superovulation protocol on the distribution of ovine embryos at different stages of development. Abstract: The compatibility between the embryo development stage and the estrous cycle moment of the embryo recipient is an important factor in the multiple ovulation and embryo transfer (MOET) progra... ... Repository: BDPA Publication year: 2019
FSH dose and strategy of administration during ovarian stimulation alter the gene expression profile in ovine cumulus-oocyte complexes. Ovarian stimulation is an important tool to increase the number of oocytes obtained by laparoscopy for the in vitro production of embryos (IVP). In sheep, different concentrations of FSH administered... ... Repository: BDPA Publication year: 2017
The influence of different methods of frozen-thawed ovine spermatozoa selection on sperm capacitation and viability after incubation. Abstract: Sperm capacitation is an essential event for fertilization; however, it decreases the sperm lifespan and viability. The aim of this study was to evaluate the effects of four sperm selection... ... Repository: BDPA Publication year: 2015
L-carnitine supplementation during vitrification did not improve survival and quality rates, but altered CrAT and PRDX1 expression in in vivo-produced ovine embryos. Embryo cryodamage is observed mainly at metabolic and molecular aspects and it impairs post warming quality and survival rates. This study aimed to evaluate the effect of L-carnitine (LC) supplementat... ... Repository: BDPA Publication year: 2017
Ovine resistance against Haemonchus contortus-globin subtype feature? Hair sheep breeds, as Santa Inês, are well-known for improved natural resistance and/or resilience against gastrointestinal infections, especially by Haemonchus contortus, compared to wool breeds, suc... ... Repository: BDPA Publication year: 2023
Improved mucosal response against hemonchosis related to Beta A allele of ovine beta-globin gene. Two B-globin haplotypes have been identified in domestic sheep: A and B. Repository: BDPA Publication year: 2023
