  ABSTRACT: A biological experiment was conducted to study the effect of panchagavya and Andrographis paniculata as alternatives to antibiotic growth promoter on broiler production and carcass characteristics with one hundred and eighty commercial, straight run day-old broiler chicks. The chicks were fed basal diet (T₁), basal diet with virginiamycin -20 mg/kg (T₂), basal diet with panchagavya -7.5 g/kg (T₃), basal diet with A. paniculata -2.0 g/kg (T₄), basal diet with probiotics -0.5 g/kg (T₅) and basal diet with mannanoligosaccharide (MOS) - 2.0 g/kg from 1 to 28 days and 0.5 g/kg from 29 to 42 days growing period (T₆) for 6 weeks period. The result revealed that the mean body weight and weight gain of T₆, T₅ and T₃ groups were significantly (P<0.05) higher as compared to the body weight of T₂ and T₁ groups at 6 weeks of age. The feed consumption did not show any difference between treatment groups. The FCR was (P<0.05) better in T₄ (1.87) compared to T₁ and T₂ groups, which recorded inferior FCR (2.04 each) at 6 weeks of age. Livability did not differ between treatment groups from 1 to 6 weeks of age. The carcass characteristics, cut-up parts of carcass and sensory qualities of meat did not differ due to dietary supplements.

  ABSTRACT: The influence of sunflower acid oil (SFAO) usage on production performance, carcass traits and economics of broilers were studied. SFAO was analyzed for its ME value by conducting metabolic trial and result revealed that the AME and TME value of SFAO were 4.398 and 4.453 kcal/g, respectively. The feeding trial was conducted by using two hundred commercial, straight run day-old broiler chicks. These chicks were randomly grouped into five treatments with four replicates of ten chicks each and fed basal diet (T<SUB>1</SUB>), basal diet with 1 (T<SUB>2</SUB>), 2 (T<SUB>3</SUB>), 3 (T<SUB>4</SUB>) and 4 (T<SUB>5</SUB>) percent of SFAO for a period of six weeks. The results revealed that there was no significant difference in body weight gain, cumulative feed consumption, cumulative feed conversion ratio and livability between treatment groups from first week till the end of the experiment. The carcass yield, abdominal fat pad weight and thickness also did not differ significantly between treatments. Inclusion of SFAO at 1, 2 and 3 percent in broiler diet increased the net profit per kg live weight by 2.8, 1.8 and 3.7 percent, respectively as compared to control group. It was concluded that 3 percent SFAO can be safely included in broiler diet without affecting production performance with increase in net profit per kg live weight.
