Effect of Shrimp Liquid Extract on Growth Performance, Carcass Traits, Biochemical Parameters and Immunological Responses of Broiler Chicken

The present study was conducted to investigate effect of shrimp liquid extract on growth performance, carcass traits, immunological responses, and biochemical parameters evaluation of broiler chickens. A total of 360 day-old Ross 308 broiler chicks were randomly allocated to five experimental treatments, with six replicates of 12 birds each. The dietary treatments comprised five different levels (0, 1, 1.5, 2, and 2.5 ml/l) of shrimp liquid extract added to the drinking water of the birds in a completely randomized design over a 35-day trial period. Results showed that supplementation of broiler chickens with different concentrations of shrimp liquid extract, particularly at 2 and 2.5 ml/l, resulted in improved performance metrics. Notably, these concentrations showed optimal results in terms of carcass yield, weight gain, and organ weights such as breast, thigh, and heart. Serum lipid fractions were not affected by the shrimp liquid extract. However, birds receiving the extract exhibited lower levels of serum creatinine and uric acid, along with higher urea levels. Furthermore, the shrimp liquid extract significantly boosted antibody titers against AIV (Avian Influenza Virus), NDV (Newcastle Disease Virus), IBD (Infectious Bursal Disease) and IBV (Infectious Bronchitis Virus) post-vaccination. Specifically, broilers given 1.5 to 2.5 ml/l of the extract displayed markedly higher antibody titers against various diseases compared to those receiving lower concentrations. Supplementation of shrimp liquid extract in water for broiler chickens at concentrations of 2 and 2.5 ml/l positively impacted performance metrics, organ weights, serum biochemistry parameters, and antibody response against various diseases.
