Article Synopsis
- Feeding low iron milk substitutes contributes to anemia in neonatal dairy calves, often leading to the need for iron dextran injections on their first day of life.
- The study found that while iron supplementation increased serum iron levels, it did not significantly affect serum ferritin levels and that diseased calves had lower iron concentrations compared to healthy ones.
- Results indicated significant correlations between red blood cell count, hemoglobin, and hematocrit levels, highlighting the complexity in using serum ferritin as a reliable anemia indicator in very young calves.
Background And Aim: The mortality rate of perinatal calves is high, particularly in dystocia cases. Besides detectable conditions such as trauma or amniotic fluid aspiration, the potential salience of cardiological diseases in neonatal bovine deaths has received little attention. This study aimed to compare the electrocardiographic parameters of calves born under conditions of dystocia and eutocia.

Aim: In this study, we evaluated whether the onset of puberty can be suppressed by implantation of a slow-release GnRH implant (4.7 mg deslorelin) in juvenile rams.
Background: Swine dysentery (SD) is a diarrheal disease in fattening pigs that is caused by the strongly hemolytic species Brachyspira (B.) hyodysenteriae, B. hampsonii and B.

Low iron levels are commonly caused by feeding whole milk without the addition of dietary supplements and led to the most frequent cause of anemia in calves. Other reasons for the development of anemia include congenital iron deficiency, malnutrition, bleeding ulcers, or bloodsucking parasites.

- - Swine dysentery (SD), a significant diarrheal disease affecting pigs, is caused by various Brachyspira species, particularly B. hyodysenteriae, with limited previous research on its strain types and drug resistance in Germany.
- - A study analyzed 116 B. hyodysenteriae isolates from German pigs over 26 years, revealing that most belonged to three major sequence types (ST52, ST8, and ST112), and identified several new sequence types as well.
- - The study found varying levels of antimicrobial resistance, with 39.1% of strains resistant to both tiamulin and valnemulin, and confirmed the constant presence of several virulence and iron acquisition-related genes across the
