Previous research has shown that eastern gamagrass (EGG; Tripsacum dactyloides L.) will survive winter climatic conditions common throughout central Wisconsin, and will produce yields of dry matter (DM) ranging approximately from 7,000 to 10,000 kg/ha annually when managed with a 1-cut harvest system. The objective of this research was to determine whether the fibrous nature of this perennial w...

Three types of cattle (Angus x Hereford yearling steers, Charolais x British breed steer calves and Hereford heifer calves) were evaluated for their response to different feeding systems utilizing high moisture corn, corn silage and soybean meal as major feed ingredients. Feeding ing systems for steers included: A = 85% concentrate; B = 40% concentrate; C = two phase, with switch from all corn ...

Mixed model analysis of data from 32 studies (122 diets) was used to evaluate the precision and accuracy of the omasal sampling technique for quantifying ruminal-N metabolism and to assess the relationships between nonammonia-N flow at the omasal canal and milk protein yield. Data were derived from experiments in cattle fed North American diets (n=36) based on alfalfa silage, corn silage, and c...

We previously reported that milk production by dairy cows was increased by adding specific xylanase-rich (XYL) and xylanase-cellulase enzymes to corn silage-based diets containing 0 or 10% bermudagrass silage. This study examined effects of adding XYL on the intake and performance of lactating dairy cows consuming a totally mixed ration (TMR) formulated with a greater proportion of bermudagrass...

A study was conducted to investigate the effects of physically effective neutral detergent fiber (peNDF) content of dairy cow diets containing corn silage as the sole forage on intake, chewing, ruminal pH, microbial protein synthesis, digestibility, and milk production. A second objective was to compare current methods of measuring peNDF to determine the most suitable approach for use in ration...

the chemical composition, in situ ruminal degradability coefficients of dry matter (dm), and nutrient digestibility in sheep were evaluated for corn silage (cs) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (i) as follows: (1) untreated cs (control); (2) cs + i at half of the recommended level; (3) cs + i at the recommended level (3  1010 colony forming...

ABSTRACT This study aimed to evaluate the productive performance, dry matter intake, apparent digestibility and ingestive behavior of feedlot calves fed corn silage from feed out face trench silos with different types sealing. The animals were divided into three treatments four repetitions: Conventional seal - double-sided polyethylene 110µm thickness; Double-sided 200µm Double composed double ...

this experiment was conducted to determine the effects of propionic acid, formic acid, molasses and molasses plus urea on chemical composition, microbial population, ruminal degradability of dry matter (dm) and crude protein (cp), and aerobic stability of corn silage. prior to ensiling, whole crop corn was chapped and treated with water (control), propionic acid (1%), formic acid (0.8%), molass...
