Reduced Glutathione in the Freezing Extender Improves the In Vitro Fertility of Ram Epididymal Spermatozoa
This study was aimed to improve the freezability and post-thaw fertility of ram epididymal spermatozoa by the addition of antioxidants into the freezing extender. Ram epididymal spermatozoa were frozen either at the presence of L-glutamine (2.5 or 5 mM), sericin (0.25 or 0.5%), reduced glutathione (GSH, 2.5 or 5 mM), or in freezing medium without supplement (Control). Immediately after thawing, the motility, functional membrane integrity and DNA damage of the thawed spermatozoa were not significantly different between groups. After 3 h post-thaw incubation at 39 °C, however, the total motili...

Pregnancy-associated glycoprotein profile in milk and its relationship with the circulating level during early pregnancy in goats
In conclusion, the PAG level in milk and peripheral circulation is affected by the day of gestation during early pregnancy and the optimal time to carry out first pregnancy diagnosis using milk or plasma based ELISA is on and after d 28 of gestation. The strong relationship and high agreement of milk PAG with its level in peripheral circulation supports that milk (both whole and skim milk) is a good alternative to plasma for early pregnancy diagnosis from d 28 to d 51 and can effectively be used as a marker of placental functions and fetal health in goats.

Faecal excretion of moxidectin in lambs and its persistence in different environmental conditions
Publication date: Available online 27 February 2019Source: Small Ruminant ResearchAuthor(s): Susana G. Hentz, Maria Angela M. Fernandes, Michelle Del Bianchi, Felix.G.R. Reyes, João Kleber G. de Souza, Fábio M. Giannotti, Alda L.G. MonteiroAbstractThe faecal excretion profile of moxidectin (MOX) was evaluated in Suffolk lambs (n = 7) with mean body weight (BW) of 36.06 ± 3.23, using a completely randomized experimental design. The animals received a single subcutaneous dose of 0.2 mg/kg BW. Faecal samples were collected 6, 12, 18, 24, 30 and 36 hours (h), and 5...

Electrocardiographic, endocrine and biochemical stress indices of electroejaculated Egyptian Baladi goat bucks
In conclusion, although repeated EE causes acute stress response which increases with repetition, the response appeared transient and not deleterious to the cardiac activity and semen characteristics evidenced by non-persistent significant increases in CTnI and absence of significant changes in the standard semen characteristics of the bucks. Additionally, ECG might be beneficial in assessing the welfare of electroejaculated bucks. Further assessment of heart rate variability (HRV) indices of bucks after EE using frequency and non-linear indices in a larger animal population is recommended. (Source: Small Ruminant Research)

Antioxidant, tyrosinase and urease inhibitory activities of camel αS-casein and its hydrolysate fractions
Publication date: April 2019Source: Small Ruminant Research, Volume 173Author(s): Lydia Addar, Chawki Bensouici, Saliha Si Ahmed Zennia, Saliha Boudjenah Haroun, Abderrahmane MatiAbstractThe aim of this study was to investigate the effect of pancreatic enzymes hydrolysis of camel αS-casein on their antioxidant, tyrosinase and urease inhibitory activities. Isolated αS-casein was hydrolyzed, fractionated and assayed for their antioxidant properties by using four complementary tests; namely, ABTS•+ scavenging, hydroxyl radical scavenging, ferrous ion chelating and β-carotene-linoleic acid assays. The in ...

Genotyping of Prion protein in black merino sheep from the Iberian Peninsula
In conclusion, we reported high richness in haplotypes in this sheep, but its distribution critically depends on the studied flock. This genetic richness enables to analyze different scenarios before implemented breeding programmes. In this way the application of a breeding programme to control scrapie appears to be a less challenging task. (Source: Small Ruminant Research)
