Effect of cellulase-glucanase-xylanase combination on the nutritive value of Telfairia occidentalis leaf meal in broiler diets

Telfairia occidentalis leaves were purchased fresh from local farmers, sun dried and milled into T. occidentalis leaf meal (TOLM). The proximate analyses revealed that TOLM contained 35.14 ± 0.44% crude protein; 9.61 ± 0.01% fat; 12.68 ±  0.02% crude fibre; 10.87 ± 0.02% ash; 9.04 ± 0.13% dry matter and 3.25 ± 0.01 kcal/ g gross energy. Eight broiler starter...

Hepatic pathologies in the brackish water catfish (Chrysichthys nigrodigitatus) from contaminated locations of the Lagos Lagoon complex

Several toxicological studies into the effects of aquatic pollutants on the liver of teleost fish exist in literature. The focus on the liver in these studies is predicated on its central nature in the scheme of biotransformation and excretion of xenobiotics following exposure in polluted water bodies. As a consequence of the latter primary role of the liver in these processes it is regarded as...

A comparative study of the gross structure and distribution of spermatogonia-like cells in the testis of pre-pubertal and mature adult rats

The testis of pre-pubertal and those of mature adult albino rats were physically divided into three segments with a view to studying histologically the gross structure and distribution of spermatogonia-derived cells (spermatogonia,spermatocytes, spermatids and mature spermatozoa) in the seminiferous tubules in these segments.  After using 50% Mezo stain (organic), spermatogonia-derived...
