Anticoccidial effect of mananoligosacharide against experimentally induced coccidiosis in broiler

Abstract

The aim of this study was to find the effect of mananoligosacharide (MOS) in comparison with amprolium hydrochloride on performance and integrity of gut in experimentally induced coccidiosis in broiler. A total of 300, day-old male broiler chickens (Ross 308) was randomly allocated to four treatments. Each group was further divided into five replicates of 15 birds each. Group A was kept as control; group B was contaminated with Eimeria tenella, while groups C and D were infected with E. tenella and treated with MOS (0.8 g/kg feed) and anticoccidial drug, amprolium hydrochloride (12 g/100 l water), respectively. The results showed that weight gain, feed intake, and feed conversion ratio (FCR) were significantly higher (P < 0.05) in infected + MOS-treated group compared to the other groups. The result of oocyte per gram (OPG) was significantly higher (P < 0.05) in the group infected with coccidiosis during 5th, 7th, 10th, and 12th day post infection (dpi). Furthermore, the OPG was significantly lower (P < 0.05) in infected groups treated with MOS and amprolium at the studied periods (5, 7, and 10 dpi). At 12 dpi, the infected group treated with MOS showed significantly lower OPG compared to the other groups suggesting the effectiveness of MOS in comparison to amprolium. The result of pinpoint hemorrhages, thickness of cecal wall, bloody fecal contents, and mucoid contents in the cecum were significant highly (P < 0.05) in birds fed with infected oocytes. It was also noted that the differences were not significant in these parameters between amprolium and MOS-treated birds showing the effectiveness of the prebiotic agent. It was concluded from the results of the present study that MOS improved growth performance and reversed the lesions of E. tenella.

Anticoccidial effect of garlic (Allium sativum) and ginger (Zingiber officinale) against experimentally induced coccidiosis in broiler chickens

“…The oocysts of Emeria species were taken from infected caeca following the procedure of Chand et al (2016). Briefly, caecal contents were immersed in 2.5% potassium dichromate solution for overnight.…”

“…Samples were kept in the refrigerator for determination of OPG. The oocysts counting were done through Mc Master Techniques as described by Chand et al (2016). Faecal samples (2 g) were mixed in 10% (w/v) NaCl solution.…”

“…At the end of the experiment, three birds were selected randomly from each group and were slaughtered. Ceca were separated and processed for histopathological examination as described by Chand et al (2016). About 1 cm thick tissue of ceca was cut and placed in 10% buffer formalin.…”

“…Coccidiosis is one of the major protozoan diseases of poultry caused by genus Emeria. This organism mostly affects the gastrointestinal tract causing reduced feed intake, weight gain, worsen feed efficiency and higher mortality (Tanweer et al 2014;Chand et al 2016). Massive economic losses are associated with the outbreak of coccidiosis in the form of morbidity and mortality of the birds (Abudabos et al 2017).…”

Effect of organic acid blend andBacillus subtilisalone or in combination on growth traits, blood biochemical and antioxidant status in broilers exposed toSalmonella typhimuriumchallenge during the starter phase

“…As a result of these circumstances, the poultry researchers are focusing on the alternative to antibiotics to optimize gut health and improve animal performance (Wu et al 2011;Chand et al, 2016;Khan et al, 2016;Raza et al, 2016). One such alternative possessing growth-promoting characteristics is organic acid, which can maintain gut health and improve animal performance by balancing normal gut flora (Sultan et al 2015).…”
