단백질수준별 급여시기가 계육생산에 미치는 영향
Effects of Dietary Protein Levels and Feeding Regimes on Performance of Broilers
초록
본 시험은 육계사료에 있어서 가장 경제적이고 효율적인 단백질 수준별 급여시기를 구명하여 육계사육의 생산성을 높이고자 실시하였다. 단백질 수준이 25, 23, 20 및 18%인 4가지 사료를 급여시기를 달리한 3개 처리구에 Aber Acres계 육계초생추 270수를 공시하여 1986년 6월 24일부터 1986년 8월 11일까지 7주에 걸쳐 시험을 실시한 결과를 요약하면 다음과 같다. 1. 증체량은 단백질 수준이 높아질수록 향상되었으며, T
This experiment was conducted to study the most economical and effective dietary protein level and feeding regimes in the performance of broilers. Four kinds of dietary protein level (25, 23, 20 and 18%) were prepared for this experiment. This experiment was carried on for 7 weeks and the results were shown as follows; 1. Increasing the dietary protein level resulted in a significant increase in the body weight gains (P〈0.05). 2. With a higher level of the dietary protein, the feed intake tended to be increased and the feed efficiency had same trends. 3. Increasing the dietary protein level resulted in a significant increase in the protein requirement per kg body weight gains (P〈0.05). 4. Viabilities were not affected by the different dietary protein levels. 5. The highest income had attained in the highest level of protein supplement, and the middle level of protein supplement was not higher than the lowest one. Conclusively, the highest level of protein supplement was considered to be adequate for the broiler's productiveity and income.
