“…The most commonly used Zn supplements in poultry feed are Zn sulfate (ZnS) and Zn oxide, which are of inorganic origin. In recent years, organic Zn sources for feed supplementation have become popular in livestock and poultry production [13]. The addition of Zn in poultry feed has a positive effect on the growth and immunity of broilers.…”

Heat stress can cause intestinal inflammation, impaired barrier integrity, and decreased immunity in poultry. While zinc is known to mitigate the adverse effects of heat stress, how the dietary supplementation of different sources and levels of it can improve the heat stress capacity of Chinese landraces remains unclear. This study investigated Xueshan chickens, which are an important local breed in China. The effects of different levels of ZnS and Zn-Prot M on their intestinal immune function under heat stress were compared. We found that different levels of ZnS and Zn-Prot M could effectively reduce the secretion level of IL-6 in the serum, and 60 mg/kg was optimal. Compared with ZnS, Zn-Prot M significantly increased duodenal villus height and VH/CD ratio. ZnS and Zn-Prot M effectively increased the villus height and villus width in the jejunum and ileum at 74 and 88 days old, with the 60 and 90 mg/kg groups outperforming other groups, and Zn-Prot M was more effective than ZnS. Both ZnS and Zn-Prot M significantly down-regulated TNF-α, IL-1β, and MyD88 in 102-day-old duodenum, and IL-1β, IL-6, and NFKBIA in jejunum and ileum at 74, 88, and 102 days old, with 60 mg/kg Zn-Prot M determined as optimal. In conclusion, our study demonstrates that Zn-Prot M is superior to ZnS in improving intestinal immunity in Xueshan chickens, and 60 mg/kg is the optimal addition dose.

“…The shift in research topics from growth and performance in the 1990s to meat quality and antioxidant status in 2010s suggests that increasing numbers of researchers were gradually becoming involved in studies addressing the quality of meat and antioxidant status in farm animals. Several studies have been performed demonstrating the protective and beneficial effects of CTM on animal production, health and, eggshell quality [95], enriched egg content [96] and other metabolic variables in animal nutrition, such as acid-base [30] and antioxidant status [30,96,97]. Therefore, this intellectual structure and network analysis provides insight into the evolution and emerging trends in chelate research and allows researchers to identify key research areas and potential gaps in current research.…”

The purpose of this study was to look at research trends in the application of CTM in animal nutrition in order to identify current and emerging challenges, as well as to examine the intellectual structure of the subject. The intellectual structure of CTM was examined using keyword and reference analysis. The research community includes all research and review articles published in journals indexed in the Web of Science database during the years 1990–2022. The results showed that the terms zinc, co-occurring 331 times, performance (324 times), and copper 216 (times) were the main and hotspots of research in the field of chelate. The data suggest that the most important keywords during the study period were zinc, copper, pig, bovine, metabolism, and bioavailability. The terms health, muscle, beef, trace elements, and dietary supplements represent emerging topics in CTM, as research began to focus on these areas during the years 2017–2022. The country with the greatest number of published articles was the United States of America. This bibliometric analysis showed that countries are focusing on the effects of CTM on the health and musculature of cattle through dietary supplementation with trace elements. According to the identified hot and emerging topics, this research can serve as a roadmap for a global comprehensive scientific plan and policy.

“…Moreover, Zn is necessary because it functions as a cofactor in over 240 enzymes and aids in the metabolization of nutrients such as carbohydrates and proteins, thereby increasing growth and reproductive efficiency [8]. Zinc in broiler diets can be organic zinc (e.g., Zn protein, Zn amino acid, or Zn picolinate) or inorganic zinc (e.g., ZnCl2, ZnSO4, or ZnO) [9]. The National Research Council (NRC) [10] recommends a zinc level of 40 mg/kg in broiler diets, which can be supplemented with inorganic or organic forms.…”

T HE objective of this study was to evaluate of nano-zinc oxide and zinc sulfate on thyroid hormones, histomorphometry and microbial in the small intestine. A total of 108 Rose 308 chicks (1d old) were randomly divided into six groups with three replicates per group, each having 18 birds. Treatments include: group one (control with basal diet),group two diet supplemented with nano-zinc oxide 40 mg/kg , group three diet containing zinc sulfate 110 mg/kg , group four subjected to high ambient temperature 40± 2 up to 4 h /day , group five was exposed to high ambient temperature 40± 2 up to 4 h /day and were dietary supplemented with nano-zinc oxide 40 mg/kg , group six was exposed to high ambient temperature 40± 2 up to 4 h /day and were dietary supplemented with zinc sulfate 110 mg/kg. The results showed a significant increase in thyroid hormones and thyroid stimulating hormone (TSH), villi height, villi width, crypt height, crypt width, goblet cell, apparent surface area, Lactobacillus population with a reduction of E. coli in nano-zinc oxide and zinc sulfate compared with control and height ambient temperature. It was concluded that nano-zinc and zinc sulfate improved thyroid function, intestinal morphology and microbial populations in broiler.
