“…However, due to its low absorption rate, unstable chemical properties, and environmental pollution capacity, IOZ has been gradually replaced by organic zinc (OZ), which has good palatability, high chemical stability, lipophilicity, and bioavailability [6,7]. Previous studies have shown that the addition of OZ to feed (protein zinc, amino acid chelated/complexed zinc, and polysaccharide zinc [8,9]) can alleviate diarrhea [10], improve immune function [11] and antioxidant capacity [12], promote intestinal health [13], and enhance reproductive performance [14], thus supporting the healthy growth of animals.…”

The aim of this study was to investigate the effect of dietary supplementation with zinc (Zn) amino acids at different concentrations on immunity, antioxidant capacity, and gut microbiota composition in calves. Twenty-four one-month-old healthy Angus calves of comparable body weight were randomly divided into three groups (four males and four females in each group) based on the amount of Zn supplementation added to the feed the animals received: group A, 40 mg/kg DM; group B, 80 mg/kg DM; and group C, 120 mg/kg DM. The experiment ended when calves reached three months of age (weaning period). The increase in dietary Zn amino acid content promoted the growth of calves, and the average daily weight gain increased by 36.58% (p < 0.05) in group C compared with group A. With the increase in the content of dietary Zn amino acids, the indexes of serum immune functions initially increased and then decreased; in particular, the content of immunoglobulin M in group A and group B was higher than that in group C (p < 0.05), whereas the content of interleukin-2 in group B was higher than that in the other two groups (p < 0.05). In addition, the content of superoxide dismutase and total antioxidant capacity in the serum of calves in group B was higher than that in group C (p < 0.05), and the MDA level was lower than in group C (p < 0.05). Moreover, alpha diversity in the gut microbiota of calves in group B was higher than that in group A and group C (p < 0.05); the dominant phyla were Firmicutes and Bacteroidota, whereas the dominant genera were Unclassified-Lachnospiraceae and Ruminococcus. Linear discriminant analysis showed that the relative abundance of Bacteroides in the gut microbiota of calves in group B was higher than that in group A, and the relative abundance of Prevotellaceae-UCG-003 was higher compared to that in experimental group C. Thus, dietary supplementation of 80 mg/kg of Zn amino acids to calves could improve the immune function and antioxidant capacity, as well as enrich and regulate the equilibrium of gut microbiota, thus promoting the healthy growth of calves.

The study was conducted to investigate the effects of copper (Cu) sources and levels on mineral utilization, tissue copper residues, and lipid metabolism in Arbor Acres broilers. A total of 640 male broilers were randomly divided into 5 groups with 8 replicates per group and 16 broilers per replicate. The experiment was used in a 2 × 2 + 1 factorial experiment design. Broilers in the control group were fed a basal diet, and animals in the other four groups were fed basal diets supplemented with Cu from copper sulphate and copper methionine. Copper concentrations of the experimental diets were 20 and 40 mg Cu/kg dry matter. A metabolism trial of 4 days was conducted during the last week of experimental feeding. Neither Cu source nor Cu level affected average daily gain, average daily feed intake or feed gain ratio (P > 0.05). Broilers fed 40 mg Cu/kg diets had lower plasma cholesterol than those in the control group (P < 0.05). Copper supplementation decreased (P < 0.05) plasma low-density lipoprotein cholesterol but did not alter plasma high-density lipoprotein cholesterol concentrations or plasma triglyceride concentrations. Copper sulphate supplementation increased (P < 0.05) liver Cu but did not alter pectorals Cu, heart Cu, tibia Cu and tibia P. Broilers fed 40 mg/kg Cu from copper sulphate had a lower (P < 0.05) tibia Ca level. The concentration of liver Cu in the broilers fed copper methionine diets was higher (P < 0.05) than that in those fed copper sulphate. Compared with copper sulphate (100%), the relative bioavailability value of copper methionine was 117%. In conclusion, the relative bioavailability of copper methionine obtained in this study was greater than that of copper sulphate. Copper plays an important role in plasma lipids and in the digestion of dietary Ca in broiler chickens.
