Haematological changes in the blood of Clarias gariepinus fed Chrysophyllum albidum seedmeal replacing maize

This study was conducted to investigate growth response of C. gariepinus fed diets containing C. albidum seed-meal replacing Five isonitrogenous diets containing maize which was replaced by C. albidum at a rate of 0,25, 50, 75 and 100% were made. Without C. albidum seed-meal served as the control, experimental diets were assigned randomly to the tanks and each group was fed 5% body weight in equal proportion per day. The fish fed diet 1 had the highest PCV while the fish fed diet 3 had the PCV. There was significant difference (p0.05) in the PCV of the fish fed diet 2, diet 3, diet 4, diet 5. A similar trend as observed for PCV was also Hb, RBC, MCV, MCH and MCHC. There was no significant difference (p>0.05) in the WBC of the blood of the fish fed various treatments so also were neutrophyls and lymphocytes

Effect of Cooking and Roasting on Nutritional and Anti-Nutritional Factors in Kenaf (Hibiscus Cannabinus L.) Seed Meal.

The effect of cooking and roasting on levels of nutrients and anti-nutritional factors in Kenaf (Hibiscus cannabinus) seed meal was investigated. Significant (p < 0.05) variation existed in the nutrient levels among the raw, cooked and roasted kenaf seed meal. Roasting resulted in a significant (p < 0.05) increase in crude protein and mineral composition. The processing methods had no significant (p > 0.05) effect on the phytic acid but significantly (p < 0.05) reduced the tannin content of the kenaf seed meal. While cooking significantly (p < 0.05) reduced the trypsin inhibitors, roasting did not significantly (p > 0.05) alter the trypsin inhibitory activities in Kenaf seed meal  when compared with the unprocessed kenaf seed meal.
