Performance and health of broiler chickens fed low erucic acid, lower fiber pennycress (CoverCressTM) grain
ABSTRACT: CoverCress (low erucic acid, lower fiber pennycress) is being developed as a cover crop to be planted in the fall after corn and harvested in the spring prior to planting soybeans. Two experiments were conducted to evaluate 2 lines of the whole grain (CCWG-1: natural mutation and mutation...

| description | ABSTRACT: CoverCress (low erucic acid, lower fiber pennycress) is being developed as a cover crop to be planted in the fall after corn and harvested in the spring prior to planting soybeans. Two experiments were conducted to evaluate 2 lines of the whole grain (CCWG-1: natural mutation and mutation breeding; CCWG-2: gene edited) and the whole grain pretreated with the potential palatability agent copper sulfate (CCWG-1-CuSO4; CCWG-2-CuSO4) as an ingredient for broilers. In Experiment 1, CCWG-1-CuSO4 was included in the diet at 0, 4, and 6% for 41 d. Feed intake, body weight gain, feed conversion, processing characteristics, organ weights, serum thyroid, macropathology and histology data were collected. In Experiment 2, broilers were fed diets containing Control, 2% CCWG-1, 4% CCWG-1, 4% CCWG-2, and 4.35% CCWG-1-CuSO4 for 42 d. Feed intake, body weight gain, feed conversion, organ weights, serum thyroid, blood chemistries, macropathology, and histology data were collected. In Experiment 1, feed intake and body weight were diminished with no effect on feed conversion for the birds consuming diets containing CCWG-1-CuSO4. In Experiment 2, feed intake and body weight were lower with no difference in feed conversion in birds fed diets containing greater than 2% CoverCress grain during d 0 to 28. During d 28 to 42 no difference in feed intake, body weight and an improvement in feed conversion was observed in birds fed all of the CoverCress grain products. In both experiments no significant negative effects were observed in processing, liver, kidney, and thyroid weights, T3, T4, blood chemistries, macropathology, and histopathology between the control and any of the CoverCress grain treatments. No difference in performance was observed in birds fed the mutant (4% CCWG-1) and gene-edited (4% CCWG-2) products. Pretreating CoverCress grain with copper sulfate did not have a significant effect on improving palatability. In conclusion, CoverCress grain can be safely fed to broilers when included at a target rate of 4% in diets and with total glucosinolate levels not to exceed 4.9 µmoles g-1. |
