“…Sharma and Fernando (32) observed an accumulation of lipid globules within the duodenal villus epithelial cells of E. acervulina infected birds, indicating that intracellular lipid processing or transport across the basolateral cell membrane of the enterocyte may be compromised. Furthermore, Adams et al (33) reported coccidiosis challenged birds had an improvement in lipid digestion when supplemented with cholic acid, indicating that bile salt synthesis or secretion may be impaired during an infection. In the current experiment, jejunum villi height was not influenced by coccidiosis vaccination at 12 d post-hatch when the greatest impacts of vaccination on nutrient and energy digestibility were observed.…”

An experiment was conducted to quantify the timing and magnitude of the effects of coccidiosis vaccination on the growth performance, apparent ileal digestibility (AID) of nutrients and energy, intestinal morphology, and plasma carotenoids and nitric oxide in broilers. Treatment groups consisted of 3 coccidiosis control methods [unvaccinated, unmedicated (NC), in-feed chemical coccidiostat (PC), and live oocyst vaccination (VAC) at day of hatch] administered to male Cobb broilers reared in floor pens. Body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) were determined at 12, 16, 20, 28, and 36 d. Blood and ileal digesta were collected from birds in 10 replicate pens of each treatment at 12, 16, 20, and 36 d to evaluate plasma carotenoid and nitric oxide concentrations and determine nutrient AID and IDE. Jejunal samples were taken at 12, 20, and 36 d for morphological measurements. Oocyst shedding in VAC birds was confirmed by increased oocyst counts and decreased carotenoid concentrations (P < 0.05) when compared with PC birds, with no differences (P > 0.05) in nitric oxide concentrations. At 20 d, BWG and FI were lowest (P < 0.05) in VAC birds, intermediate in NC birds, and highest in PC birds, with no differences in FCR (P > 0.05). By 28 and 36 d, FCR was higher (P < 0.05) for VAC and NC birds but BWG and FI of VAC birds were similar (P > 0.05) to PC birds. At d 12, IDE and AID of nitrogen and ether extract were lower (P < 0.05) in VAC birds than PC birds. At d 16, AID of nitrogen was similar (P > 0.05) between PC and VAC birds, whereas AID of ether extract remained lower in VAC birds than PC birds. No differences in AID of nutrients or IDE were observed (P > 0.05) between VAC and PC birds at 20 or 36 d. No differences (P > 0.05) in jejunal morphology were observed at any time point. Overall, VAC elicited a transient reduction in AID and IDE, particularly for lipids, that diminished by d 20.

“…The detrimental effect of infection was also reflected in the highest OPG recorded in the excreta collected on post-infection days 6, 8, 9 and 14 and in the lesion score of the duodenum on post-infection day 6. The duodenum is the site of invasion for E. acervulina, which does not cause a drastic increase in mortality, but has a negative impact on the digestion, absorption and assimilation of nutrients (Adams et al, 1996).…”

The aim of the experiment was to evaluate the anticoccidial efficacy of supplementing feeds with herbal extract blend containing garlic (Allium sativum), sage (Salvia officinalis), echinacea (Echinacea purpurea), thyme (Thymus vulgaris) and oregano (Origanum vulgare) extracts in broiler chickens experimentally infected with 170.000 sporulated oocysts of Eimeria acervulina, E. tenella, E. maxima and E. necatrix at 12 days of age. A total of 280 Ross 308 broilers were randomly allocated into 5 groups with 7 replicates of 8 chickens per replicate. The experimental dietary treatments were formulated by supplementing the basal maize-soyabean meal diet. The experimental design allocated the groups as follows: 1. uninfected birds and an unsupplemented diet; 2. uninfected birds and the diet supplemented with the herbal extract blend at a level of 1 g/kg feed (200 mg of each herbal extract/kg); 3. infected birds and an unsupplemented diet; 4. infected birds and a diet with the addition of coccidiostat diclazuril at a level of 1 mg/kg feed; and 5. infected birds and a diet supplemented with the herbal extract blend at a level of 1 g/kg feed (200 mg of each herbal extract/kg). Throughout the 42 days of the experimental period, performance parameters, mortality, lesion score, oocyst output, and serum carotenoid concentration were recorded. Dietary supplementation with the herbal extract blend increased growth performance to the level found in the group fed the coccidiostat and in the non-challenged groups. The number of oocysts per gram of excreta did not differ significantly between the groups fed the herbal extract blend and the group receiving the coccidiostatic supplement. The herbal extract blend had no effect on mortality, lesion score, with the exception of the duodenum, or blood carotenoid concentration.

“…Coccidiosis usually reduces body weight gain in broiler chicks as a result of reduced feed intake, digestibility and absorption of macronutrients [17]. It is accepted that weight gain is the more sensitive variable to coccidiosis and anticoccidial treatments [18].…”

BackgroundCoccidiosis is one of the most economically important diseases affecting the poultry industry. Currently, anticoccidial drugs used in veterinary clinical showed many deficiencies, and new control measures are urgently needed. Many plant-derived drugs, such as herbal extracts, showed effects with less drug residues and resistance. Development of herbal medicine as the anticoccidial drug is one of the most prospective method for treating coccidiosis.Methods“Shi Ying Zi” powder is consisted of Cnidium monnieri (L.) Cuss, Taraxacum mongolicum Hand-Mazz and salt with the proportion of 55: 40: 5 (g/g/g). 200 1-day-old broiler chicks free of coccidiosis were equally divided into 10 groups: normal group, untreated group, 4 protective groups (positive control group and three “Shi Ying Zi” powder groups) and 4 therapeutical groups (positive control group and three “Shi Ying Zi” powder groups). At 11th day of age, the chicks in the four protective groups were prophylactically supplemented with “Shi Ying Zi” powder at the doses of 5g/kg, 10g/kg and 15g/kg and monensin (100mg/kg), respectively. At 14th day of age, chicks except those in blank group were inoculated with 2×104 sporulated oocysts of E. tenella. When the first hemorrhagic fecal was found, therapeutical drugs started administration. The low (5g/kg), medium (10g/kg) and high doses (15g/kg) of “Shi Ying Zi” powder were added into the diet, respectively. Sulfachloropyrazine sodium (positive control) was added into water (1g/L). The anti-coccidial index, biochemical parameters and tissue lesions were determined from 4 d post infection to 8 d post infection.ResultsSupplement with “Shi Yin Zi” powder for 3d prior to infection or after infection could improve the survival rate and relative growth rate and alleviate the pathological changes in the cecum, liver and kidney. “Shi Yin Zi” powder could recover the contents of glutamic-pyruvic transaminase, creatinine, albumin and triglycerides in serum. The hemorrhage and total number of oocysts in feces were reduced. The anti-coccidial index reaches to 165. The anti-coccidial effects were equal to positive controls (monensin and sulfamlopyrazine). Conclusions“Shi Ying Zi” powder possesses potent anticoccidial effect and exhibits the potential to control E.tenella infection.
