Influence of feeding all-vegetable protein versus animal protein dietse on performance ,carcass characterstics and immune response of broiler chicks reared in hot climate

Abstract: Five hundred and ninety four, one-day old, Hubbard broiler chicks were used to compare between the effects of feeding diets containing all- vegetable protein versus mixture of vegetable and animal protein sources on the performance, carcass characteristics and the immune response of broiler chicks reared in hot climate.
Results indicated that live body weights of chicks fed on vegetable protein diets such as soybean meal (SBM), corn gluten meal (CGM) and/or sunflower seed meal (SFM) were not significantly different from those of the control fish meal (FM) diet, but significantly higher than those obtained from meat and bone meal (MBM) diet. However, body weights of chicks fed on diets containing sesame seed meal (SSM) were significantly lower than those fed either on FM or other vegetable protein diet. Feed conversion of chicks fed on SBM, SBM+CGM or SFM diets were equal to or significantly better than those obtained from FM diet. Carcass characteristics and nutrient digestibilities were not significantly affected by feeding chicks either on animal or vegetable protein sources, but those fed on SFM had significantly lower % dressing weight and total edible parts. However, chicks fed on FM diet had significantly higher abdominal fat. There were no significant differences in antibody titer against sheep red blood cells (SRBC) for chicks fed either on vegetable or animal protein source, but chicks fed on SSM+SBM produced lower antibodies compared to the control FM groups. Chicks fed on SBM+CGM or SFM+CGM recorded the highest economical efficiency, whereas, the lowest economical efficiency was recorded by MBM diet. It is concluded that feeding diets containing vegetable protein sources such as SBM, SFM and/or CGM had a performance equal or superior to that obtained from the diet containing animal protein sources in terms of body weight, feed conversion, mortality rate, carcass characteristics and immune response. However, vegetable protein diets are more safe and economical.
Keywords: vegetable proteins, animal proteins, broiler performance, immune response, hot climate.
