| Summary: | The study aimed to determine the protein requirements for basic life and growth on Napu. Four Napus with an average 3.2 kg body weight were used in this study. 4 X 4 Latin square design was used in this research. Feed treatment were contained four levels of protein, namely 10%, 15%, 20% and 25%.
Research results showed that protein levels did not significantly affect dry matter intake, nitrogen in faeces and nitrogen in urine. Consumption of nitrogen at levels 25% was higher (P <0.05) than 10%, 15% and 20% 0f protein level. Consumption of nitrogen on the protein level 10% and 15% were not
significantly different. Nitrogen balance increased (P <0.05) with increased levels of protein in feed. Retention of total nitrogen at the highest protein level was 0.92 g / kg BW and in the lowest level of 0.25 g/kg BW. The highest body weight gain was obtained at the protein level of 25% followed by the level of
20%, 15% and 10%. BW gain was not significantly different from the retention of nitrogen (R2= 0896). Nitrogen requirement was estimated at the time of retention of nitrogen equal to zero ie 0.20 g/kg BW/day, equivalent to 8.1% protein in feed. Nitrogen requirement for growth is 0.67 g N/kg BW/day,
equivalent to 20.4% protein in feed |
