| Popis: | A study was conducted to evaluate three different levels of Azadirachta indica dried leaf meal, using diets supplemented with 0 (negative control), 1.25 g antibiotic/kg (positive control), 1.25, 2.5 and 5.0 g leaf meal/kg of feed. The chicks were randomly divided into 15 separate floor pens (each 10×15 feet) each comprising 20 chicks and three pens (replicates) per treatment group following completely randomised design. At 28 and 42 d BW and feed conversion ratio (FCR) were determined. At 42 d, five birds per pen were slaughtered to measure dressing percentage and lymphoid organs weight was also determined. Serum protein, serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), alkaline phosphatase (ALP), serum cholesterol, tissue cholesterol, growth hormone, thyroxine and haematological indices were also determined. At both 28 and 42 d, birds fed diets supplemented with 2.5 g/kg of leaf meal had significantly greater BW and better FCR than those fed diets with 1.25, 5.0... |
