  Objective: The present study was performed to determine the influence of dietary Acetic Acid (AA) supplementation on growth performance, intestinal histomorphology, blood hematology and serum constituents of broilers. Methodology: A total 200 chicks were randomly divided into five experimental groups with four replicates each (10 chicks/replicate) in a complete randomized design experiment. Treatments were as follow: (AA0: control, AA1: basal diet+0.1% acetic acid kg–1, AA2: basal diet+0.2% acetic acid kg–1 and AA3: basal diet+0.3% acetic acid kg–1). Results: The results showed that AA supplementation improved weight gain (p<0.001) and feed conversion ratio (p<0.001). Generally, acetic acid supplementation at 0.3% level improved bird’s performance during 2-6 weeks of age. Increased intestinal length and higher intestinal weight were recorded in AA treated birds. Significant reduction in pH of proventriculus and ventriculus (p<0.01) was observed with in dose related manner. No significant effects were observed on dressing percentage. Histological observations revealed that intestinal morphology professed positive effects under AA treatment. Furthermore, the effect of dietary AA supplementation was significant (p<0.05) only on lymphocytes count and heterophil/lymphocyte ratio. It is obvious that blood of birds fed AA3 diet had the highest concentration of calcium, phosphorous, total protein and globulin comparing with the control diet and other levels of AA. The best results of all parameters were observed in AA3. Conclusion: Based on the results, it could be concluded that AA supplementations in feed employs positive effect on performance and intestinal histomorphology of broilers.

  Present paper reports the effects of sugar cane juice (SCJ) on immune responses and its protection against Eimeria (mixed species) infections in broiler chickens. Experiment 1 was conducted to test the dose efficacy of SCJ and its effects on chickens against coccidiosis. Maximum weight gain per day was recorded in chickens given SCJ @ 400 mg/kg body weight. Significantly (P < 0.01) low mortality and increased body weight gain per day were recorded in chickens administered SCJ orally and challenged with mixed species of genus Eimeria. Furthermore, mild hemorrhages, lower lesion scores (+1), and significantly lower number of oocysts shed in faeces were recorded in immunized chickens compared to control. Experiment 2 was carried out to evaluate the immunomodulatory effects of SCJ on cellular and humoral responses. Highest antibody titres (1:1024-1:16; GMT 367.28) were recorded in chickens administered SCJ @ 400 mg/kg body weight in comparison with control (1:16-1:2; GMT 2.82). To demonstrate the cell mediated immunity (CMI), amplitude of toe-web swelling 72 h post avian tuberculin injection was recorded in the experimental and control groups. Maximum swelling (8.13 ± 0.21 mm) was recorded in the experimental group as compared to control (1.04 ± 0.10); indicating higher cell mediated immune response. From these results it was concluded that SCJ elicit a significantly higher cellular and humoral responses compared to control, which may provide protection against Eimeria infections (mixed species) in chickens.
