Khurshaid Anwar* and Ihsanuddin
ABSTRACT
A study was conducted to evaluate the effect of replacement of soya bean meal with yeast single cell protein on broiler antibody titer against Newcastle disease virus (NDV). A total of 120 chicks out of 150 chicks were selected randomly and were grouped as; YSCP-0, YSCP-5, YSCP-10 and YSCP-15 having 0, 5, 10, and 15% replacement of soybean meal with yeast single cell protein (YSCP), respectively. Each group had 3 replicates of 10 chicks each. The trial was continued for 35 days after a week of adaptation period. No significant effect was observed on antibody titre against NDV in all the groups. From outcomes of the present study it is concluded that yeast single cell protein should not be used or tried as a replacement meal for soybean meal in broiler chicks to enhance immunity against NDV.
