Special Issue Information

Dear Colleagues,

In modern agriculture, it is crucial to comprehend how nutrition affects the production and reproduction of livestock. Nutrition is a critical factor in guaranteeing the quality and quantity of animal products as well as the overall sustainability of livestock operations. It is critical to understand how livestock's nutritional state affects both their production and ability to reproduce. In order to satisfy the growing demand from consumers for high-quality animal products, it is crucial to have a thorough understanding of how to optimize nutrition for livestock.

Exploring the complex relationship between diet and animal production and reproduction is the focus of this Special Issue. It digs into the creation and evaluation of dietary plans intended to boost reproduction effectiveness, increase livestock performance, and guarantee the production of high-quality animal products. A wide variety of livestock species, including cattle, poultry, swine, and more, will be covered in the contributions to this Special Issue, which will also draw on multidisciplinary research from disciplines including animal science, veterinary medicine, and nutritional science.

This Special Issue's research articles will provide useful insights into the most recent developments in livestock nutrition; feeding methods; and their effects on animal health, production, and reproduction. We want original research, viewpoints, and reviews to encourage a thorough conversation on this important subject.

In conclusion, this Special Issue will highlight the impact of nutrition on both quantity and quality within the agricultural sector, clarifying the critical role it plays in determining the future of livestock production. It is our goal to solve urgent issues and realize promising prospects in enhancing animal nutrition through interdisciplinary cooperation and creative research.

Copper (Cu) and zinc (Zn) are trace minerals with multiple biological functions, playing roles in fetal development and immune regulation. Despite their known significance, research on Cu and Zn administration and supplementation for pregnant mares is insufficient. This study aims to evaluate Cu and Zn serum concentrations monthly throughout the year and through pregnancy in Polish Konik mares. The study was conducted in 2020 on 36 mares from the Polish state stud farm, with 24 mares in the pregnant group and 12 mares in the non-pregnant group. Monthly blood samples were collected, and serum Cu and Zn concentrations were measured. The total Cu concentration in the serum of all mares was higher (p < 0.0001) in August and September (13.98 ± 3.00 μmol/L) than in May, June, July, and November (11.04 ± 2.74 μmol/L). Similarly, the total Zn concentration was higher (p < 0.0001) in August, September, October, November, and December (19.80 ± 9.72 μmol/L) than in May, June, and July (14.50 ± 6.94 μmol/L). No evidence of a linear relation between Cu and Zn concentrations was demonstrated (slopes difference p < 0.001). No differences in Cu (p > 0.05) or Zn (p > 0.05) concentrations were found between pregnant (Cu: 12.08 ± 3.01 μmol/L; Zn: 18.02 ± 9.03 μmol/L) and non-pregnant (Cu: 11.23 ± 2.51 μmol/L; Zn: 18.59 ± 10.37 μmol/L) mares in any of the examined months of the year. In conclusion, the month of the year, rather than pregnancy, affects serum Cu and Zn concentrations. Full article
