Early embryo losses, progesterone and pregnancy associated glycoproteins levels during summer heat stress in dairy cows
(2021)Objectives of this study were to characterize the effects of heat stress on pregnancy associated glycoproteins (PAG) and progesterone and its involvement in embryo survival. In trial 1, blood samples collected from days ... -
Effects of capsicum and propyl-propane thiosulfonate on rumen fermentation, digestion, and milk production and composition in dairy cows
(2020)Essential oils may affect rumen fermentation, nutrient digestion, and milk production and composition. The objective of this study was to test the effects of capsicum oleoresin (CAP) and propyl-propane thiosulfonate (PTSO) ... -
Modelling Human Brucellosis Based on Infection Rate and Vaccination Coverage of Sheep and Goats
(2022)In this study, the vaccination coverage, serological sampling and infection rate of sheep and goats were evaluated as predictors for the modeling of human brucellosis in Greece. The human bru-cellosis disease frequency per ... -
Neospora caninum, A potential cause of reproductive failure in dairy cows from Northern Greece
(2020)Neospora caninum infection has been reported in a large number of intermediate hosts, such as ruminants, rabbits, mice, etc. but neosporosis has emerged as a serious disease in cattle and dogs worldwide. Abortions and other ... -
Neosporosis and toxoplasmosis are two prevalent and important protozoses in dairy cows in small farms from Thessaly, Central Greece
