Effect of Nanozinc Supplementation on Haematological and Blood Biochemical Profiles in Goats

Nano Zinc Oxide Supplementation Improves Growth Performance and Health of West African Dwarf Goats

“…Neutrophil concentration values which were below reference range reported Daramola (2005). Our results are in agreement with the report of Swain et al (2019), who reported significant difference in neutrophil level with higher concentration in control group than the supplemented groups that received 25 to 50mg/kg nanoZin. In concordance to this study, Someyaet al (2007) reported that dietary Zinc deficiency increased the number of eosinophil and neutrophils and decreased the number of lymphocytes, suggesting a change in white blood cell distribution.…”

“…Similar finding observed by Elaminet al reported an increase in WBC of goat kids fed 33mg/kg ZnSO4 as against the control were not significantly affected by treatment differences, which is in agreement with findings in this study, while Kegleyet al, (2001) and Swain et al (2019) reported no significant difference in total WBC and lymphocyte when 360 mg Zn/d of ZnSO4 or Znamino acid complex was supplemented in beef calves and 25 to 50mg/kg nano zinc fed to goats, respectively. White blood cell values observed in this study was found to be at par with those reported by Daramola (2005) and Merck (2011).…”

“…However, and contrary to this result, Mandal and Das (2010) and Swain et al (2019) reported similar PCV in crossbred calves after supplementing 35 mg/kg of Zn as zinc sulphate or zinc propionate and in goats fed 25 and 50mg/kg nano zinc respectively.…”

“…Zinc may be supplemented in form of feed inorganic, organic or nano source and the nanometer dimension for zinc is term nanozinc (nZn; Swain et al, 2019). Nano form of supplementation increases the surface area that would increase mineral absorption (Desai et al, 1997).…”

Reproductive Performance of Rahmany Ewes Fed Basal Ration Supplemented With Different Sources of Zinc

“…Prasad andKundu, 1995 andEnjalbert, 2009 reported that Zinc in particular and other nutrients of new-born depends on maternal transfer via the placenta and the colostrum or the milk. In this respect, Swain et al (2019) reported that supplementation of daily ration with Zn at level of 50 mg/ kg feed DM for inorganic and 25 or 50 mg Nano Zn had no significant effect on RBC (10 6 / μl), WBC (10 3 / μl), PCV (%), neutrophil (%), lymphocytes (%), eosinophil (%), monocyte (%), haemoglobin (g/dL), ALT (IU/L), AST (IU/L), ALP (IU/L) and creatinine (mg/dL) levels of goat blood. However, globulin (g/dL) and total protein (g/dL) significantly varied among the treatment groups (P<0.01) without affecting blood albumin (g/dL) and A/G ratio levels.…”
