Four groups of 10 animals each of the domestic buffalo (Bubalus bubalis) were slaughtered at the ages of 9, 14, 21, and 26 months of age, respectively. The chemical composition of each of the longissimus dorsi and the semitendinosus muscles of these animals was determined and compared with various other carcass traits. Intramuscular fat has significantly increased when the animals were 21 months old. Carcass side had no significant effect on the chemical composition of the comparable muscles. The only significant differences in the chemical composition of the 2 muscles were in moisture and protein contents. The carcass weight has correlated significantly fat deposition and musculature of the carcass, but the correlations with the chemical composition were those of fat percent with caudal fat weight, kidney fat weight with moisture percent and those of protein percent with moisture percent.

Blood pictures of the European silver eel Anguilla anguilla L. were described. Blood was obtained from control (immature) male and female silver eels, at ripe stage after developmental maturation of gonads by intramuscular injection with chorionic gonadotropin hormone (HCG) for male and Carp pituitary (CP) mixed with (HCG) for female, and after long starvation for both sexes.
In normal blood (control), the haematological parameters such as haemoglobin, haematocrit, red blood cells were higher in male than in female.
Changes in blood picture were used as criteria of systemic response to experimental conditions.The effects of developing testes led to significant decrease in haemoglobin, haematocrit, whereas developing ovaries showed more significant decrease in haemoglobin, haematocrit, red blood cell count. As a result of such decrease in haematological parameters in both male and female, the experimented fish suffered from certain degrees of anaemia.
Fish of extended starvation revealed sharp decrease in all haematological parameters.
An abnormal blood film is seen in nutritional anaemia. There is marked anisocytosis with predominantly hypochromic irregular microcytes and macrocytes
