“…Our results show that the effect of A. galli infection on the copper liver level is completely different to that of coccidiosis (SOUTHERN & BAKER, 1982). This difference is probably due to the different migratory patterns of the two parasites during their developmental stages.…”

“…They concluded the sulphate and acetate forms of copper were superior to either the oxide or the carbonate ones. SOUTHERN & BAKER (1982) reported that copper absorption was dramatically increased by intestinal coccidiosis (Eimeria acervulina) in chicks. Thus an important interrelationship was demonstrated between intestinal parasitism and excess copper ingestion.…”

“…All data were analyzed by analysis of variance, using procedures appropriate for factorial treatment designs (Steel and Torrie, 1980). Because the original kidney Cd data were heteroscedastic, one was added to all observations and the data were then transformed to natural logarithms before statistical analysis.…”

“…Previous research (Fox et al, 1971) with Cd and cysteine gave variable results when a single dose of cysteine was given to Japanese quail consuming high Cd (75 mg/kg) diets; tissue Cd levels, however, were not examined. Also, Eimeria acervulina-induced coccidiosis was found in the case of excess copper feeding to exacerbate the deposition of this element in soft tissues (Southern and Baker, 1982). Eimeria acervulina is a common protozoan parasite which attacks the duodenum of the chick and results in significant financial losses to poultry producers.…”

Three experiments were conducted with 9-d-old crossbred chicks to determine the effect of supplemental L-cysteine.HCl.H2O on tolerance to excess dietary Cd. Cd levels of 30 or 60 mg/kg added to a fully fortified corn-soybean meal diet depressed both body weight gain and gain:feed ratio and increased kidney Cd concentration. Supplemental cysteine (i.e., .59% L-cysteine.HCl.H2O) did not alleviate the depression of weight gain or gain:feed ratio due to Cd feeding but did decrease kidney Cd accumulation. Eimeria acervulina infection (i.e., duodenal coccidiosis) depressed rate and efficiency of weight gain and resulted in increased Cd concentrations in kidney tissue. Cystein supplementation increased kidney cadmium concentration even further in E. acervulina-infected birds.

“…Supplementation of 0.75% Met in broilers fed low crude protein diet and challenged with a mild coccidia infection increased the severity of coccidiosis, indicating the negative impact of Met supplementation on coccidiosis when birds were fed low crude protein diet ( Teng et al, 2021 ). However, there is also some research showing that the requirements of total sulfur amino acids (TSAA), Met + cysteine (Met + Cys), may be higher when chickens are infected with Eimeria species ( Southern and Baker, 1982 ; Ren et al, 2020 ).…”

Coccidiosis is a major intestinal challenge that causes economic loss to the broiler industry. Two battery cage studies were conducted to evaluate the effect of trace minerals, source and dose of methionine on growth performance and gut health of broilers subjected to Eimeria challenge. Experiment #1 consisted of 9 treatments of 2 × 2 × 2 factorial design + 1 arrangement with main factors of methionine (Met) sources (DL-Met vs. 2-hydroxy-4-(methylthio)-butanoic acid (HMTBa)), total sulfur amino acid (TSAA) levels (high vs. low; ±5% of recommended level), and sources of trace minerals (TM) Zn:Cu:Mn in the form Inorganic trace minerals (ITM) in sulfates (80:20:100ppm) vs. mineral methionine hydroxy-analogue bis-chelate (MMHAC, 40:10:50ppm), each with 8 pens of 10 birds. Experiment #2 consisted of 2 treatments--ITM [ZnSO4:tribasic copper chloride (TBCC):MnSO4 110:125:120ppm] and MMHAC (Zn:Cu:Mn, 40:30:40ppm), each with 36 pens of 10 birds. All birds except for treatment 9 in experiment #1 were orally gavaged with 1x, 4x and 16x recommended dose of coccidiosis vaccine on d0, d7 and d14, respectively. Data were subjected to one-way and/or three-way ANOVA, and means were separated by Fisher’s protected LSD test with significance at p ≤ 0.05. In experiment #1, factorial analysis revealed the main effects of TSAA level and TM, but not Met source. High TSAA level improved body weight and cumulative feed intake at 14, 20, and 27d. MMHAC improved body weight at 14, and 27d; feed intake at 14, 20, and 27d; and cumulative FCR at 27d vs. sulfates. One-way ANOVA analysis showed that birds fed MMHAC and high levels of TSAA regardless of Met source had similar body weight as unchallenged birds on d27. In experiment #2, MMHAC improved body weight and cumulative FCR, and reduced jejunal IL-17A gene expression on d28. In summary, in broilers subjected to Eimeria challenge, supplementation of the reduced levels of bis-chelated trace minerals MMHAC improved growth performance compared to high levels of ITM (sulfates or TBCC), which might partially result from better immune response, high levels of TSAA improved growth performance, Met source had no effect. Supplementation of both bis-chelated trace minerals MMHAC and high levels of TSAA could overcome the growth performance challenge issue due to coccidiosis.
