Restricted feeding and high concentrate diets are potential strategies for growing dairy heifers. Ruminal manipulation with additives such as Saccharomyces cerevisiae yeast culture (YC) has been shown to alter digestibility when added to this type of diet. An experiment was conducted to investigate the ruminal fermentation and in situ digestibility of diets with 3 different levels of forage to ...

The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (Yuyeon hybrid) was harvested at height of 5, 10, and 15 cm from the ground level. Each cutting height was rolled to make round bale and ensiled for 100 days. After 100 days of ensiling, pH of silag...

One of the most frequently asked questions regarding feeding the performance horse is when to feed before a competition. Several studies have evaluated how feeding grain before exercise affects plasma concentrations of nutrients and hormones and substrate utilization during exercise (Rodiek et al., 1991; Zimmerman et al., 1992; Lawrence et al., 1993; Lawrence et al., 1995; Stull and Rodiek, 199...

The objective of this study was to evaluate the effect either a limited forage intake or concentrate supplementation prior adaptation high-concentrate diets on dry matter intake, ruminal pH, bacteria, and protozoa Nellore cattle. experiment designed as two 3×3 Latin square, six cannulated steers were used. Each experimental period composed by three feeding phases: pre-adaptation (14 days), (12 ...

The aim of the study was to investigate the effect of Saccharomyces cerevisiae (SC) live yeast culture on microbial protein supply to small intestine in Kivircik male yearlings when fed with different ratio of forage and concentrate diets. Four Kivircik male yearlings with permanent rumen canula were used in the experiment. The treatments were allocated to a 4x4 Latin square design. Diet I cons...
