“…However, it has been reported that supplementation of diets with Znmethionine had no effect on feed intake in goats (5), growing lambs (17,18), and beef steers (6), which is in contrast to our findings and other reports (4).…”

“…The improved dry matter intake observed in this study following Zn supplementation is in agreement with the previous findings of Garg et al (4). However, it has been reported that supplementation of diets with Znmethionine had no effect on feed intake in goats (5), growing lambs (17,18), and beef steers (6), which is in contrast to our findings and other reports (4).…”

“…To each bottle, one of the following treatments was applied: 1) control (C; no supplemental zinc), 2) 20 ppm of Zn as ZnS, or 3) 20 ppm of Zn as ZnP. Samples were incubated in triplicate and cumulative gas production was monitored at 2, 4,6,8,10,12,15,19,24,30,36,48,72, and 96 h after incubation. Three bottles with incubation medium only were used as blanks to correct the gas production values for gas release from the rumen contents.…”

“…Some researchers (2,3) have reported greater bioavailability for organic Zn sources than that observed for inorganic forms, including Zn oxide and Zn sulfate. It has been demonstrated that organic Zn is transported intact from the intestinal lumen into mucosal cells, increasing tissue supply of Zn and thereby improving animal productivity (4).…”

“…In contrast, Mandal et al (6) and Jia et al (7) indicated that DM, CP, acid detergent fiber (ADF), and neutral detergent fiber (NDF) digestibility were not affected by dietary Zn in bull and goat, respectively. In addition, Garg et al (4) found that supplementation of the basal diet with 20 mg of organic Zn/kg DM improved ADF digestibility in lambs, but DM, CP, and NDF digestibility were not affected.…”

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.
