“…In addition, the reports on the effect of the probiotic application on the growth and the fattening performance of lambs and carcass characteristics are inconsistent (Baranowski et al, 2007;Titi et al, 2008;Whitley et al, 2009). Besides, Knuth et al (2020) indicated that the addition of Zn to ration for 63 days increased the DM intake, but did not improve the growth performance of lambs. It was also reported that there was no effect of Zn addition to the diets of lamb on growth performance (Solaiman and Min, 2019).…”

This study aimed to evaluate the effects of ground or steam-flaked corn and zinc-enriched yeast addition to grower pellet feed on fattening performance, rumen papillae development, and some blood parameters in lambs. For this purpose, thirty-six Kivircik male lambs were selected and divided equally into six groups: basal diet containing pellet feed without different corn form and yeast (control), basal diet 80% + ground corn 20% (PGC), basal diet 80% + steam-flaked corn 20% (PFC), PGC + Zn-enriched yeast (PGCZnY), PFC + Zn-enriched yeast (PFCZnY), and control + Zn-enriched yeast (PZnY). They were fed for 56 days according to the diets mentioned above. At the conclusion of the evaluations in fattening performance, rumen papillae development, and some blood parameters, there were no significant differences in body weight gain, average daily gain, average daily feed intake, and feed efficiency among the experimental groups. In the PGCZnY group, rumen papillae length was found to be higher than the other experimental groups. At the end of the trial (day 0), leukocyte and lymphocyte counts decreased significantly only in the control group compared with the other groups in the present study. Serum blood urea nitrogen (BUN) values, analyzed at the beginning and at the end of the trial, increased significantly in all groups except in the PGCZnY group. Supplementation of Zinc-enriched yeast to ground corn can be used for increasing ruminal papilla length, however decreasing the serum BUN levels in lambs during the fattening period.

“…The impact of a combination of Zn sources (Zn amino acid complex with ZnSO4) supplied at dietary quantities that meet or exceed NRC requirements has been studied to a lesser extent in fine-wool feeder lambs. (Knuth, 2020). In the late 1990s, chromium (Cr) was considered a fundamental mineral in domestic animal production.…”

The purpose of this study was to evaluate the effects of chromium and zinc dietary supplements in an organic form on some productive performance and physiological responses in growing Zaraibi goats. Twenty eight male Zaraibi goats (4 months old, 15.72 ±1.40 kg BW) were allocated randomly into four treatment groups (7 animals in each). The first group (T1) was given a control diet without supplements. The control diet contained 3 mg/kg from organic chromium (Cr) was given to the second treatment group (T2). The third group (T3) received the control diet containing 40 mg/kg of organic zinc (Zn), whereas the fourth treatment group (T4) was fed on the control diet containing 3 mg Cr + 40 mg Zn/kg. The experimental period was 90 days included a 10-day digestibility trails. Results showed that, animals in groups T2, T3, and T4 had higher values for daily dry matter intake (DMI), final body weight (FBW), average daily gain (ADG), and total gain (TG) as compared to the control group (T1). Organic Cr and Zn supplementations improved feed efficiency and feed conversion ratio. The digestibility coefficients and feeding values of the treated groups were improved than those of the control group. The serum total antioxidant capacity, were significantly higher in groups fed Cr or Zn-diets than in the control group. Thus, administration of Cr and Zn in organic form has a significant impact on Zaraibi goats growth and digestion, as well as improved antioxidant and biochemical parameters.
