Efeito do cilostazol na produção in vitro de ovinos

Vet. zootec; 30 (), 2023
O objetivo deste estudo foi avaliar o efeito da inclusão de cilostazol no meio de maturação in vitro de oócitos sobre produção in vitro de embriões ovinos. Para isso, foram realizadas colheitas de oócitos oriundos de ovários obtidos em abatedouro por meio do método de aspiração folicular com ...

Antioxidant capacity, reproductive response and glucose concentration and insulin of ewes supplemented prior to insemination with orange residue

The objective was to evaluate the antioxidant capacity, glucose and insulin concentration and reproductive performance of ewes supplemented with orange residue prior to insemination. Fifty-five multiparous ewes were divided into two corrals, and 15 unbred ewes were kept individually to measure feed consu...

Use of ammonium chloride to prevent urolithiasis in sheep

Urolithiasis has a high incidence among confined sheep. It is multifactorial and may cause economic damage. Our aim was to determine the capacity of urinary acidification using ammonium chloride in sheep. Twenty-five 3-month-old male sheep were confined and randomly divided into three groups; the G200 an...

Influência da restrição alimentar e do estresse térmico sobre parâmetros fisiológicos em ovinos

Objetivou-se avaliar as alterações fisiológicas de ovinos submetidos à restrição alimentar, expostos à radiação solar e à sombra. Dez borregas mestiças foram divididas igualmente em dois grupos: grupo radiação solar - GRS, animais expostos ao sol durante o dia; e grupo sombra - GS, animais a...

Comparação dos parâmetros bioquímicos entre gestação única e gemelar de ovelhas da raça Dorper durante gestação, parto e pós-parto

Nas ovelhas, a demanda de nutrientes aumenta durante a gestação, especialmente nas últimas seis semanas, quando ocorre maior desenvolvimento do feto. Os objetivos deste trabalho foram estudar o perfil bioquímico de ovelhas durante a gestação e no periparto imediato, comparando-se gestação única ...

Assessment of serum lactate levels, blood glucose values and blood gas values in sheep, newborn lambs and placenta

Pesqui. vet. bras; 38 (9), 2018
Newborn animals, in the fetal-to-neonatal transition, usually face several challenges in their first 24 hours, including issues with acid-base balance, glycemic levels and oxygenation. Difficulties to overcome such issues have caused several deaths among newborns. Therefore, studies have been carried out...

Echocardiographic parameters and vertebral heart size (VHS) in lambs during the neonatal period

Pesqui. vet. bras; 38 (9), 2018
Due to cardiac immaturity, newborns have a different morphology and cardiac output when compared with adults. The purpose of this study was to describe the cardiac changes in echocardiographic characteristics and vertebral heart size (VHS) in newborn lambs during the neonatal period. Twenty-eight healthy...

Iron supplementation for lambs experimentally infected by Haemonchus contortus: response to anemia and iron store in the bone marrow

Pesqui. vet. bras; 38 (8), 2018
To evaluate the effect of supplementation of iron dextran on blood variables and iron metabolism in lambs experimentally infected by Haemonchus contortus, four experimental groups were used: uninfected and non-supplemented animals (GI); infected animals supplemented with iron (GII); uninfected animals su...
