The aim of the present study was the evaluation of the bioaccumulation of cadmium (Cd), Zinc (Zn), Chrome (Cr), Lead (Pb), Iron (Fe) and Copper (Cu), in the blood, serum, tail and mane of horses from the industrialized area of Milazzo (Messina, Sicily), to understand the relationships between haematological parameters: Red Blood Cells (RBCs), White Blood Cells (WBCs), Haemoglobin (Hb), Haematocrit (Hct), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), Platelets (PLTs) and the concentrations of trace elements. Blood and hair samples from 20 healthy Italian Saddle horses and water, hay and concentrates samples were obtained to determine the haemogram and mineral concentration using a Thermo Scientific iCAP-Q ICP-MS spectrometer. Descriptive analysis showed a higher concentration of Zn, Cr, Pb, Fe, and Cu in the blood and a higher concentration of Cd in the tail than other substrates. A positive correlation was found for Cr ( < 0.0001) and Zn ( < 0.01) between blood and serum substrates, for Zn ( < 0.001) between mane and tail and for Pb ( < 0.01) between blood and mane, while a negative correlation was observed for Cr ( < 0.01) between blood and tail. Results showed a close relationship between the bioaccumulation of certain trace elements in biological substrates and haematological parameters, which represent useful biomarkers suggesting further studies, given the role of haematological parameters in athletic horses.

Department of Animal Nutrition and Feed Science, Faculty of Animal Science, Universitas Gadjah Mada, Yogyakarta, Indonesia.
Background: The lactation period is a crucial period where the nutritional status and the mother's environment influence milk production, impacting organ differentiation, function, and structure in the baby's body.
Aim: The study aimed to determine the impact of providing lactating rats with quail egg supplements enriched with marine macroalgae on their physiological condition (blood cells, lipids, blood glucose, antioxidant activity, and prolactin hormone levels) and the growth of their offspring.
Methods: The study involved 25 lactating Sprague Dawley white rats aged 3 months old and weighing approximately 200 g divided into five treatment groups thus; T0 as the control, T1 with quail eggs enriched with commercial feed, T2 with quail eggs enriched with 3% of marine macroalgae, T3 with quail eggs enriched with 4% of marine macroalgae, and T4 with quail eggs enriched with 5% of marine macroalgae, which received one quail egg for 21 days.

Hematological and biochemical parameters in the blood of working Belgian Shepherd dogs: An age-related study.
Open Vet J
November 2024
Department for Clinical Sciences, University of Sarajevo-Veterinary Faculty, Sarajevo, Bosnia and Herzegovina.
Background: Age-related changes in physiological parameters are crucial in understanding the health and performance of working dogs, particularly those in demanding roles such as military and law enforcement. However, limited research exists on how aging affects the hematological and biochemical health of these dogs.
Aim: This study aims to characterize age-related variations in hematological and biochemical parameters in working Belgian Shepherd dogs to provide insights that could inform health management strategies for these animals.
Assessment of Serum Levels of Vitamin D and Selected Biochemical and Hematological Parameters in Rats Post-Immunized with Inactivated COVID-19 Virus.
Arch Razi Inst

Department of Basic Sciences, Faculty of Veterinary Medicine, Semnan University, Semnan, Iran.
Serum levels of vitamin D (VD) are inversely correlated with the incidence or severity of COVID-19. This study aimed to investigate the effects of inactivated COVID-19 virus (ICoV-19) immunization on VD levels, as well as biochemical and hematological parameters in adult male Sprague-Dawley rats. Twenty rats were randomly divided into two groups of 10: the control group (group I) and the ICoV-19-receiving group (group II).
