Abstract

Copper and zinc are two micro-minerals important for maintenance of health and optimal production. This research sought to establish the levels of copper and zinc in goats to provide data for further studies on micronutrients, their interaction and deficiency states. Health status of sampled goats were clinically evaluated. Blood samples were collected through jugular venu-puncture. One (1) ml of each blood sample was acid digested with concentrated nitric acid, assayed for zinc and copper using atomic absorption spectrophotometer. Haematology was also done using whole blood as a health index. Most of the goats looked apparently healthy, while few goats showed emaciation, crusty skin lesions, varying degrees of achromotrichia (change in coat colour) and rough hair coats. 89.9 % had hypocupraemia, while none of the sampled goats showed zinc deficiency. However, zinc toxicity occurred in 84.4 % of the sampled goats when compared to reference values. Haematology showed varying result, ranging from monocytic hypochromic anaemia to polycytaemia. All anaemic animals were found to be deficient in copper. The study has highlighted the presence of copper deficiency and or zinc toxicity in goats and forms a preliminary data to the study of the fate of small ruminant health in the face of micronutrient imbalance.Keywords: Copper, Zinc, Micronutrient, Haematology, Hypocupraemia, Achromotrichia, Goats

Abstract

Currently, no information exists regarding internal and external morphometrics and their correlations in Funisciurus anerythrus and Heliosciurus gambianus. Therefore, this study examined the relationships among the internal and external morphometrics of the two species in University of Ibadan, Ibadan, Nigeria. Samples of adult F. anerythrus (n = 20) and H. gambianus (n = 13) were trapped from the wild at various locations within the campus. Live weights (LW), external measurements and weights of internal organs were taken. Comparisons within and between both species were carried out using T-tests and Pearson's correlation coefficient at p<0.05. H. gambianus was significantly bigger than F. anerythrus for all the measured parameters, except in ear and snout lengths. Male F. anerythrus was significantly bigger than female in LW, body length (BL) and shoulder to tail length (STL) while, female H. gambianus was significantly bigger than male in trunk circumference (TC). In male F. anerythrus, BL significantly correlates with STL (r = 0.85). In female F. anerythrus, LW correlates significantly with hind limb length (r = 0.62) and both kidneys. In male H. gambianus, LW correlates significantly with head length (r = 0.79), tail length (r = 0.81), BL (r = 0.97), STL (r = 0.87), and the weights of lungs and kidneys. In female H. gambianus, LW correlates significantly with TC (r = 0.99) and right lung weight (r = 0.92). Both species show some levels of sexual dimorphism and substantial positive correlations among the external and internal measurements. [ABSTRACT FROM AUTHOR]
