Doctoral Thesis / Dissertation from the year 2016 in the subject Veterinary medicine, grade: A, course: Poultry Nutrition - Animal science, language: English, abstract: The objective of this experiment was to determine the effect of dried blood- rumen content mixtures (DBRCM) on the performance of SASSO C44 broiler chicks. A total of 225 unsexed day old broiler chicks (SASSO C44) were randomly distributed to five dietary treatment groups in a completely randomized design and replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100%Soyabean meal(SBM)+0%DBRCM (T1), 80%SBM+20% DBRCM (T2),60%SBM+ 40% DBRCM (T3), 40%SBM+60% DBRCM(T4) and 20%SBM+80% DBRCM (T5) in 56 days of age. Both starter and finisher diets were formulated to be iso-caloric and iso-nitrogenous. Data were collected on average feed intake, body weight gain (BWG), feed conversion ratio (FCR) and mortality rate. The result revealed that the daily dry matter intake was ranged from 75.8 to 80.4g/day/bird in the entire experimental period of growth. Birds fed on T5 (75.8) was lower (P0.05) among each treatment groups. The feed conversion ratio(FCR) ranged from 2.5-2.9 and there was no statistical marked difference (P>0.05) among treatment groups. Also there was no statistical difference (P>0.05) in mortality rate. Based on the present result, it could be concluded that dried blood rumen content mixture can be included up to 60% inclusion level for starter phases and up to 80% for finisher phases of growth to replace soybean meal without any adverse effect on bodyweight gain, FCR, and mortality rate of birds.
