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...
Study on sexual maturity and levels of gonad steroid hormones in female kutum Rutilus frisii kutum (Kamenskii, 1901) during spawning season from river Sefid-Rood of the southern Caspian sea
Sexual maturity and levels of two main steroid hormones in gonads, 17-β estradiol (E2) and testosterone (T) relations which occur in female kutum Rutilus frisii kutum during spawning season from the river Sefid-Rood of the southern Caspian sea were studied using histological and radioimmunoassay. The study was carried out from February to May, 2008 using 105 fish specimen. The results of present study revealed that...
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...
