Abstract Background The focus of triticale breeding in the southern Great Plains of the United States has been to increase forage yield for autumn–winter seasons when most other forage species are dormant. This study aims to estimate the trends of

Estimating forage availability is important in optimizing livestock stocking rates. The rising plate meter was developed to estimate forage availability. It needs a calibration equation to convert its measurement to a prediction of forage mass, and p

Tall fescue (Lolium arundinaceum) infected with an endophyte (Neotyphodium spp.) generally has agronomic advantages over endophyte-free tall fescue. The objective of this study was to determine if endophyte presence (E+) or absence (E−) in three ta

The objective of this study was to examine the effects of diet energy density on ranking for dry matter intake (DMI), residual feed intake (RFI), and greenhouse gas emissions. Forty-two mature, gestating Angus cows (600 ± 69 kg body weight [BW]; bod

PurposeThe authors determine the effectiveness of the Rainfall Index Annual Forage Program (RIAFP) in offsetting yield risk of winter annual forage growers. The authors also evaluate the effectiveness in reducing risk of potential alternative weather

The objective of this study was to determine the effect of diet type on feed intake in mature Angus cows. Forty-eight gestating Angus cows (708 ± 52 kg; 7 ± 0.75 years old) were assigned to one of four drylot pens based on their genomic score for r

The upper south is a climatic transition zone from the west to the east and from the south to the north. This transition has a huge impact on forage and livestock production systems across the region. Precipitation ranges from 30 in./year in the west
