Effect of green syntheses Nano zinc oxide on performance characteristics and haematobiochemical profile of West African Dwarf goats

Abstract

A study was conducted to investigate the effect of green syntheses nano zinc oxide on performance characteristics,   haematobiochemical profile and serum zinc levels of West African Dwarf (WAD) goats. A total of 12 apparently healthy WAD goats (5 – 6 month of age, 7.3 ± 1.15 kg body weight) were randomly assigned to T1, T2 and T3 diets for 56 days in a complete randomised designed experiment. Result showed that dry matter intake (DMI) and average daily gain (ADG) significantly increased (p<0.05) across the groups with increasing levels of nano zinc oxide. The mean values of haemoglobin, packed cell volume and red blood cell were found not to be significantly different (p>0.05) among the different groups. However, there were significant differences (p<0.05) in white blood cell counts, neutrophil, lymphocytes, mean corpuscular volume and mean corpuscular haemoglobin values among the different groups. The mean values of serum glucose also did not differ among the groups; however significant variations were noticed in total protein and blood urea nitrogen as higher value were obtained in T1 (7.25) and control group (13.17) respectively as compared with other  treatments. There was no significant variation in the activities of alanine aminotransferase among the treatments, however, significant difference (p<0.05) was observed in the activity of aspartate aminotransferase as lower value was obtained in T3 (31.00) as compared  with other treatments. Result obtained on Zn concentration showed that WAD goats placed on T2 and T3 diet had significantly higher (p<0.05) levels of zinc concentration compared to control diet.
