“…Total protein (TP) is vital for the maintenance of homoeostasis in broilers. ALB content accounts for the largest protein fraction (40-60%), and it is synthesized in the liver [46]. Both TP and ALB contents in the blood are considered markers of liver function that reflect protein synthesis [47].…”

Although Iron (Fe) is an essential nutrient that plays a vital role in respiratory processes, excessive Fe in the diet can affect the health of broilers. We investigated the effects of diet supplemented with high levels of iron chelates with lysine and glutamic acid (Fe–LG) on the growth performance, serum biochemical parameters, antioxidant status, and duodenal mRNA expression of Fe transporters in broilers. A total of 800 1-day-old male Arbor Acres broilers were assigned to 5 groups, with 8 replicates each. Broilers were fed a corn–soybean meal basal diet or basal diets supplemented with 40, 80, 400, or 800 mg Fe/kg as Fe–LG for 6 weeks. The body weight (BW) was increased in the 80 mg Fe/kg treatment group, but decreased in the 800 mg Fe/kg treatment group on day 21. During days 1–21, compared with the control group, the supplementation of the 80 mg Fe/kg increased the average daily gain (ADG) and average daily feed intake (ADFI); however, the supplementation of the 800 mg Fe/kg group decreased the ADG and increased the FCR in broilers (p < 0.05). The heart, liver, spleen, and kidney indices were reduced in the 800 mg Fe/kg treatment group (p < 0.05). The supplementation of the 800 mg Fe/kg group increased the serum aspartate aminotransferase activity and the levels of creatinine and urea nitrogen on day 42 (p < 0.05). The broilers had considerably low liver total superoxide dismutase activity and total antioxidant capacity in the 800 mg Fe/kg treatment group (p < 0.05). Serum and liver Fe concentrations were elevated in the 400 and 800 mg Fe/kg treatment groups, but were not affected in the 40 and 80 mg Fe/kg treatment groups. The duodenal Fe transporters divalent metal transporter 1 (DMT1) and ferroportin 1 (FPN1) were downregulated in the Fe–LG treatment groups (p < 0.05). We conclude that a high dietary supplement of 800 mg Fe/kg in broilers leads to detrimental health effects, causing kidney function injury and liver oxidative stress.

“…In addition, Kueile et al (2019) also did not observe any significant difference on body weight gain when animals were reared on different litter materials (wood chips, dry pine leaves, used barn litter, and sand). Costa et al (2021) also reported that the use of thick sawdust or rice straw in 2 different stocking densities had no significant effect on live weight gain and slaughter weight. Likewise, Dhaliwal et al (2018) concluded that animals reared on rice hull and thick wheat straw had similar body weight.…”

“…In production, abdominal fat deposition by chickens is problematic as fat can be lost during evisceration, affecting carcass yield 50 . Costa et al 51 indicated that a higher percentage of abdominal fat characterized birds kept on wood shavings (compared to rice straw), and the differences did not affect slaughter yield. In our research, despite the differences between the groups, no relationship was observed between the carcass yield and the abdominal fat percentage.…”

Bedding material is a crucial environmental factor for chickens. Coffee husks are waste from the industry that could be reused. The study aimed to analyze the chemical composition of various bedding types and assess their impact on the performance characteristics of broiler chickens and the incidence of footpad dermatitis (FPD). Ross 308 broilers were used in the study. Birds were divided into 3 groups (216 chickens, 72 per group). Group 1 was kept on chopped straw (S). Group 2 was kept on coffee husks (CHs), and the 3rd group (PB) was kept on pellet bedding made from S and CHs in a 1:1 ratio. The dry matter (DM), crude fiber (CF), nitrogen (N), phosphorus (P), potassium (K) content, and the pH of the bedding were analyzed. Production results were examined during 42 days of rearing. FPD was assessed on a point scale. The tissue composition of the carcasses and qualitative physicochemical characteristics of the meat (pH, color, water holding capacity, drip loss) and bone-breaking strength were analyzed. Straw had a higher CF content. In total, the highest N content in CHs was noticed. P content was lower in the S, and K was the highest in the CHs group, followed by S and PB. The pH of the bedding was lower in the CHs group, higher in PB, and highest in S bedding. The DM was decreasing within the days of rearing. A significant interaction was demonstrated between the type of bedding and rearing days on the bedding (manure) composition. On days 1–14, FCR deteriorated in the PB group compared to the S group. The presence of FPD was significantly lower in the PB group than in the others. In the PB group, chickens had a higher slaughter yield than in the S group and a lower weight and liver share than in the CHs group. The weight and proportion of abdominal fat were higher in the group kept on S than on CHs. It can be concluded that coffee husks as a component of pellets had a beneficial effect on reducing FPD in chickens and their slaughter yield and enriched bedding with nutrients, which with poultry manure, could be a good fertilizer for agricultural soils after rearing. It could be recommended to use pelleted bedding.
