The comparative anticoccidial effects of herbal products with a standard synthetic anticoccidial drug on the production performance, intestinal histology, and some blood biochemical parameters in broilers exposed to experimental coccidiosis was investigated. One-day-old broiler chicks (n = 336) were randomly distributed into six groups. One group served as a control, the second was treated with the coccidial infection, the third was treated with synthetic anticoccidial drug (Elancoban), the fourth group was treated with an herbal product (Cozante), the fifth group of birds was treated with Norponin, and the sixth group was treated with Emanox. The results indicated that BWG, BW, FCR, and PEF decreased significantly (P < 0.05) in the positive control. Body weight gain, BW, and PEF were significantly (P < 0.01) high in Elancoban-treated birds. On day 25, lesion score was significantly (P < 0.01) low in duodenum, jejunum, and ceca in Elancoban-treated birds control. On day 30, lesion score was significantly (P < 0.05) low in Emanox-treated birds as compared with the positive control. Albumin concentration was significantly (P < 0.01) low in Emanox while glucose concentration was significantly (P < 0.01) high in all the treated groups compared with the positive control birds. The total antioxidant capacity was significantly (P < 0.05) high in Emanox on day 15 and 30 as compared with the positive control. The results showed that birds exposed to the natural anticoccidial products showed improved villi and total antioxidant capacity. We concluded that herbal products performed better than the positive control group.

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.

3,5-Dinitrobenzamide has been widely used as a feed additive to control coccidiosis in poultry, and part of the added 3,5-dinitrobenzamide is excreted into wastewater and surface water. The removal of 3,5-dinitrobenzamide from wastewater and surface water has not been reported in previous studies. Highly reactive hydroxyl radicals from UV/hydrogen peroxide (H₂O₂) and UV/titanium dioxide (TiO₂) advanced oxidation processes (AOPs) can decompose organic contaminants efficiently. In this study, the decomposition of 3,5-dinitrobenzamide in aqueous solution during UV/H₂O₂ and UV/TiO₂ oxidation processes was investigated. The decomposition of 3,5-dinitrobenzamide fits well with a fluence-based pseudo-first-order kinetics model. The decomposition in both two oxidation processes was affected by solution pH, and was inhibited under alkaline conditions. Inorganic anions such as NO₃ ⁻, Cl⁻, SO₄ ²⁻, HCO₃ ⁻, and CO₃ ²⁻ inhibited the degradation of 3,5-dinitrobenzamide during the UV/H₂O₂ and UV/TiO₂ oxidation processes. After complete decomposition in both oxidation processes, approximately 50% of 3,5-dinitrobenzamide was decomposed into organic intermediates, and the rest was mineralized to CO₂, H₂O, and other inorganic anions. Ions such as NH₄ ⁺, NO₃ ⁻, and NO₂ ⁻ were released into aqueous solution during the degradation. The primary decomposition products of 3,5-dinitrobenzamide were identified using time-of-flight mass spectrometry (LCMS-IT-TOF). Based on these products and ions release, a possible decomposition pathway of 3,5-dinitrobenzamide in both UV/H₂O₂ and UV/TiO₂ processes was proposed.
