The Interplay between Oxidative Stress and Fatty Acids Profile in Romanian Spotted Cows with Placental Retention.

(1) Background: Retained fetal membranes (RFM) in cattle negatively impact reproduction, calving intervals, and health. This study examined OS markers and fatty acid profiles in Romanian Spotted cattle, comparing cows with normal parturition to those with RFM. Over 9 weeks, serum samples were collected from 22 cows (7 with RFM, 15 normal) at intervals before and after parturition.

Peripartal changes of metabolic and hormonal parameters in Romanian spotted cows and their relation with retained fetal membranes.

This clinical study investigates various metabolic and physiological parameters in dairy cows during puerperium. Retained fetal membranes (RFM) is a significant postpartum complication that can affect the overall health, fertility and productivity of dairy cattle. The research focuses on changes in total proteins, albumin, glucose, triglycerides, total cholesterol, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), cortisol, insulin, and insulin-like growth factor 1 (IGF-1) levels among cows experiencing normal post-partum period (NP) and those with RFM.

Experimental infection with Toxoplasma gondii in broiler chickens (Gallus domesticus): seroconversion, tissue cyst distribution, and prophylaxis.

Toxoplasma gondii is a widespread zoonotic protozoan that infects most species of mammals and birds, including poultry. This study aimed to investigate the course of T. gondii infection and the efficacy of diclazuril and Artemisia annua in preventing infection in experimentally infected chickens.

Laboratory development of Dermacentor marginatus ticks (Acari: Ixodidae) at two temperatures.

The influence of two temperatures on the development of Dermacentor marginatus evolutive cycle was studied. Tests performed under controlled laboratory conditions at 21 °C, 80 % RH and 27 °C, RH 80 %, on ten fully engorged female ticks collected from naturally infested goats, in Cluj County, Romania. Hatched larvae were fed on white mice and the nymphs and adults on guinea pigs.
