“…Eimeria challenge significantly increased the cooking loss of thigh meat compared to that of the CON group. In contrast to our results, Chodova et al [ 32 ] reported that subclinical E. tenella infection did not affect the meat color and cooking loss of broiler chicken breast meat. Interestingly, the dietary EO preparation tended to lower the cooking loss of thigh meat compared to that of the INFECT group.…”

“…Tauer et al [ 33 ] reported that dietary oregano essential oil did not affect the pH of the breast meat but increased the meat colors when the broiler chickens were exposed to a coccidiosis disease challenge. The results of our study, supported by earlier work [ 32 , 33 ], suggest that the meat quality of broiler chickens challenged by Eimeria warrants further investigation.…”

Background Due to presence of drug-resistant Eimeria strains and raised public health safety concerns about drug residues in the meat, there is renewed interest in the search for natural alternatives to the coccidiosis control agents. This study was conducted to test the anticoccidial efficacy of oregano and Citrus spp.-based essential oils for broilers. Methods A total of 280 7-day-old broiler chicks were fed a control diet or diets with salinomycin or essential oils for up to 35 d of age. On d 14, half of the control groups and the treated groups were orally challenged with a coccidiosis vaccine at 25 times higher than the recommended vaccine dose. Control diet-fed chickens that were gavaged with phosphate-buffered saline were considered non-challenged control group. Results Eimeria challenge or dietary additives failed to affect growth performance during the 7 to 20 d growth period although essential oil-fed chickens exhibited the lowest body wight gain (P = 0.332) and the highest feed conversion ratio (P = 0.062). Oocysts in the litter were detected in the challenged control diet group and the challenged/essential oil-fed groups at 21 and 35 d, respectively. Superoxide dismutase activity in the serum was elevated (P = 0.059) in the salinomycin-fed chickens compared to the challenged controls. Alpha-1-acid glycoprotein was decreased by 28.7% in the salinomycin-fed chickens but increased by 38.1% in the essential oil group compared with the challenged control group. Challenged control group exhibited a significantly higher cooking loss of the thigh meat, compared to the non-challenged control diet group, which was marginally mitigated by dietary supplementation with essential oils. Chickens fed essential oil-added diet had the highest branched-chain fatty acids contents in the cecum. Conclusions In conclusion, this study shows that oregano and Citrus-based essential oil preparation did not affect growth performance in broiler chickens challenged with the coccidiosis vaccine nor did Eimeria-specific duodenal lesion. However, dietary essential oil preparation lowered oocysts present in litter materials and altered branched-chain fatty acids in cecal digesta. Beneficial findings of the essential oil preparation on volatile fatty acids and oocysts output may warrant further research into assessing its effectiveness and its efficacy in pathogenic field-isolate Eimeria spp.-induced coccidiosis disease model.

“…In addition to small intestine morphology, a reduction in meat yield caused by coccidiosis can be due to changes in breast muscle histomorphology. A subclinical Eimeria infection has been observed to result in a decrease in muscle fiber cross-sectional area ( Chodová et al., 2018 ) and an increase in plasma levels of 3-methyl histidine, which is associated with muscle breakdown ( Fetterer and Allen, 2001 ). Dietary 25OHD 3 has been shown to increase muscle fiber cross-sectional area ( Hutton et al., 2014 ), which can subsequently result in an increase in breast meat yield ( Vignale et al., 2015 ) in broilers.…”

Effects of the in ovo administration of vitamin D 3 ( D 3 ) and 25-hydroxyvitamin D 3 ( 25OHD 3 ) on broiler intestinal lesion incidence, performance and breast meat yield after a coccidiosis challenge were investigated. On each of 10 incubator tray levels, 10 Ross 708 broiler hatching eggs were randomly assigned to each of the following 5 in ovo injection treatments administrated at 18 d of incubation ( doi ): 1) noninjected; 2) diluent; diluent containing either 3) 2.4 μg D 3 (D 3 ), 4) 2.4 μg 25OHD 3 (25OHD 3 ), or 5) 2.4 μg D 3 + 2.4 μg 25OHD 3 (D 3 +25OHD 3 ). A 50 μL solution volume was injected into each egg using an Inovoject multi-egg injector. Four male chicks were randomly assigned to each of 80 battery cages in each of 2 rooms. Half of the treatment-replicate cages (8) in each room were challenged with a 20× live coccidial vaccine at 14 d of age ( doa ). One randomly selected bird from each of 4 treatment-replicate cages was scored for coccidiosis lesions before and 2 wk after challenge. Mean BW, BW gain ( BWG) , feed intake, and feed conversion ratio were determined for all birds from 0 to 14, 15 to 28, and 29 to 41 doa. Carcass weight, and the absolute and relative (% of carcass weight) weights of carcass parts were determined in 3 birds per treatment-replicate cage at 42 doa. Hatchability of live embryonated injected eggs and hatch residue were not affected by treatment. Across challenge treatment, birds in the 25OHD 3 treatment group experienced an increase in BWG between 29 and 41 doa when compared to the D 3 or diluent-injected birds. Furthermore, pectoralis major muscle percentage tended ( P = 0.059) to increase in birds belonging to the 25OHD 3 treatment in comparison to birds in the D 3 or diluent-injected treatments. These results indicate that regardless of challenge treatment, 2.4 μg of 25OHD 3 may increase the BWG and breast meat yield of birds relative to those that only received an injection of commercial diluent.
