Two experiments were conducted to investigate the effect of supplemental zinc (Zn) on performance, nutrient digestibility, and plasma Zn status in Zandi lambs. In experiment 1, 18 male lambs (BW = 21.30 ± 0.55 kg) were fed a basal diet containing 22.8 mg Zn/kg dry matter (DM) with no supplemental Zn (control) or 20 mg of supplemental Zn/kg of DM from Zn sulfate (ZnS) or Zn peptide (ZnP). Average daily gain and dry matter intake were higher for the lambs fed the diet supplemented with ZnP. Feed conversion ratio was significantly (P < 0.05) lower in the ZnP group compared to the control and ZnS groups. In experiment 2, an in vitro gas production technique was used to evaluate the effects of zinc source on the gas production parameters. Rate of gas production after 6 h and total production of gas after 24 and 48 h did not differ between groups. In vitro DM digestibility, short-chain fatty acids, and ME content were increased (P < 0.05) by ZnP supplementation when compared to the ZnS and control groups. The results of this study showed that feeding ZnP improves performance and digestibility of DM and could result in higher metabolizable energy and short-chain fatty acid yield.

The effects of supplementing broilers' diets with fermented cottonseed meal (FCSM) on the broilers' performance, apparent digestibility, carcass traits, and meat composition were studied. A total of 180 yellow-feathered chickens of 21 days old were randomly divided into three groups (six replicates of 10 broilers each): 1) a control group (Con), 2) a treatment group of FCSM by Candida tropicalis (Ct), and 3) a treatment group of FCSM by C. Tropicalis plus Saccharomyces cerevisiae (Ct-Sc). Results showed that FCSM supplementation improved the average daily gain and gain-to-feed ratio from the 43rd to 64th and the 21st to 64th day, respectively …

The objective of this study was to evaluate the effect of dietary red grape pomace (RGP) on amino acid digestibility (AIAAD), intestinal microflora, and antioxidant activity in the sera and liver. Sixty-six broilers were housed in battery cages. They were allocated to six cages corresponding to two dietary treatments with three replicates of each treatment. The treatments were administered from 10 to 36 days and included a control diet and a diet containing 1.5% RGP dry powder with the other components remaining unchanged, compared to the control. The RGP had a significant (P < 0.05) positive effect on the apparent metabolizable energy. The majority of coefficients of AIAAD were higher in the RGP. The ileal digestibility of threonine, serine, proline, and glycine was significantly (P < 0.05) higher in RGP. RGP had a positive effect (P < 0.05) on the content of Lactobacillus in the lower part of the ileum. The blood sera of broilers fed RGP had significantly (P < 0.05) lower 2,2-diphenyl-1-picrylhydrazyl (DPPH) and uric acid content. The RGP at a concentration of 15 g/kg in the grower diet did not affect the growth of broilers, and RGP is suitable for broiler diets to improve gastrointestinal tract functionality.
