Abstract
ABSTRACT Groups were designated as a positive control (+C), negative control (−C), Amprolium (AM1), Aloe vera, 2.5 g/l water (AV2.5) and Aloe vera 5 g/l water (AV5) during the finisher phase. The experiment was conducted using 360 broiler chicks, which were divided into five different groups. Overall feed intake was significantly (P<.01) lower in Aloe vera supplemented groups. The overall weight gain was significantly (P<.01) higher in AV5 and AMI compared to –C. No significant difference was found in the feed conversion ratio between AMI and Aloe vera-treated birds. The caecal lesion, oocysts count and intestinal lesion were significantly (P<.01) reduced in Aloe vera-treated birds. The number of heterophils and total leucocyte count significantly (P<.01) decreased, while the number of monocytes and eosinophils increased (P<.01) in the treatment groups. From the results, it is also clear that the infection increased the monocytes and eosinophils and decreased the heterophils and TLC. In conclusion, the use of Aloe vera at the rate of 5 g/l of water produced encouraging results in broilers in comparison with Amprolium.
Highlights
Among important poultry disease, avian coccidiosis is one of the economically most dangerous diseases caused by several species of genus Emeria
The European Union (EU), banned the use of antibiotics to justify them as animal feed additives (Khan et al 2012; Abudabos et al 2018; Safiullah Chand et al 2019; Nasir et al 2020)
The objective of this study was to investigate the beneficial effect of Aloe vera on the production performance, intestinal lesion score and leucocytes count in experimentally induced coccidiosis in the broiler
Summary
Avian coccidiosis is one of the economically most dangerous diseases caused by several species of genus Emeria. The protozoan enters into the intestinal tissues, leading to the pathological changes (Chand et al 2016; Ali et al 2019). This disease is typically characterized by low feed consumption; poor feed efficiency and high morbidity and mortality in the flock. A number of negative effects on health have been reported; the use of antibiotics in controlling coccidiosis is still continuing. There is an instant need to discover novel feed additives for the effective controlling of avian coccidiosis
