Abstract:
Fifteen male Nubian kids at sexual maturity ranging between (6-9) month and 15 male Nilotic kids age between (2-4) month were used in study to investigate the effect of fatting on feed intake, feed conversion ratio, body weight gain and some blood parameters which include glucose, cholesterol, total protein, albumin, urea, uric acid, ceriatinine tri glyceride, calcium, phosphor,enzymes ( GOT, GPT ), fat and glycogen
The kids were randomly divided into two groups. Group one was all Nubian males and group two were all Nilotic kids. The Nubian group contained 15 kids and the Nilotic group 15 kids. The average initial weight of the two groups matching 3.21± 1.66 and 4.21±1.66 kg, respectively
The kids were fed individually, accommodated and weekly weight and blood samples for the metabolites test were taken. This experiment continued for eight weeks (60 day). The data were than analyzed using student (T test) to examine the significance of the effect of fattening on the feed lot performance and the blood metabolites levels.
The study showed that there was no significant difference between the Nubian and Nilotic kids in feed intake, although, the Nubian kids showed significantly (p< 0.05) higher body weight gain compared to the Nilotic kids.
There were no significant differences between the Nubian and Nilotic kids in feed conversion ratio although the Nubian kids had lower value than the Nilotic kids which suggest that the feed conversion ratio of Nilotic kids was better than the Nubian.
The results of blood metabolite showed that there was no significant difference between the two groups except for creatininne level, which was significantly higher for the Nilotic kids than of Nubian.
