A new high-yielding bermudagrass hybrid, Tifton 85, produced 26% higher DM yield (P=.05) with 11% higher IVDMD (P=.05) than Coastal in two 3-yr yield trials. Tifton 78 and Tifton 85 were established in duplicate .81-ha pastures in 1988 and were grazed during 1989, 1990, and 1991 using a variable stocking rate method. Four tester steers per pasture with 269kg initial BW grazed continuously for 169d/yr beginning in April. Forage mass, targeted at 2,800kg of DM/ha, was maintained by adjusting stocking rates at 14-d intervals to correspond with ground-levelforage samples taken at 14-d intervals. Pastures received 84kg of N/hain March, June, and August of each year. Nutritive value was assessed using whole masticate samples from two esophageal cannulated steersgrazing each pasture in late May, mid-July, or early September. The 3-yr mean masticate analyses revealed similar CP for Tifton 78 and Tifton 85 in May and July, but higher (P<.05) CP for Tifton 85 than for Tifton 78 in September. The IVDMD was higher (P<.05) in May and Septemberfor Tifton 85 than for Tifton 78; and, mean and medium particle sizes were greater (P<.05) for Tifton 85 than for Tifton 78 in May, July, and September samples. The 3-yr mean ADG was similar for Tifton 78 and Tifton 85 (.65vs .67kg; P>.10); however, grazing days/hectare were higher for Tifton 85 than for Tifton 78 (1,823vs 1,319d; P<.01). Consequently, BW gain/hectare was 46% higher for Tifton 85 than for Tifton 78 (1,156vs 789kg; P<.01). Forage quality, DM yield, and grazing ...

The objective of the present study was to evaluate the accuracy and bias of direct and blended genomic predictions using different methods and cross-validation techniques for growth traits (weight and weight gains) and visual scores (conformation, precocity, muscling, and size) obtained at weaning and at yearling in Hereford and Braford breeds. |
