Abstract:
Broiler production is a prominent worldwide agricultural practice that serves as a
substantial meat supply. The efficiency of broiler production is crucial, given the
rising global demand as a result of the population growth and increasing per capita
income. Exogenous emulsifiers are a type of surfactant that have ability to enhance
the breakdown and absorption of fats and other nutrients in animal feed. Exogenous
emulsifiers promote lipid digestion by a specific method. Emulsifiers decrease the
surface tension between fat molecules and aqueous digestive enzymes, resulting in a
more effective digestion and absorption of fats. This study investigated the impact of
an exogenous emulsifier on the growth, carcass, litter traits, yield, and quality
characteristics of broiler chickens. Three hundred of 14th -day-old cobb 500 broilers
as hatched basis were arranged randomly via complete block design. There were one
treatment and six replicates per each treatment. Each treatment contained 150 birds
and each replicate contained 25 birds. Birds were fed with two types of diet, Nelna
basal diet as the control diet and Nelna basal diet with 500 g per ton exogenous
emulsifier as the treatment diet. Applying standard statistical tests and one way
ANOVA at p< 0.05, the results indicated significant differences in body weight gain
(BWG), average feed intake (AFI), feed conversion ratio (FCR), and mortality,
dressing yield, meat quality score, and nutrient utilization for the treatment group
were recorded. Key findings included a mean weekly body weight gain of 0.286 kg,
FCR of I.266, and a dressing yield of 73.86%. However, some parameters such as
abdominal fat, and fecal tests were statistically not significant (p > 0.05). Data were
analyzed using. Overall, the study suggests that exogenous emulsifiers can positively
influence broiler performance and quality, although further research is needed to
confirm these trends in non-significant areas.
