Voluntary intake of forage by ruminants is limited by forage bulk density and the rate at which forage is degraded to particles that can pass from the rumen. Two indirect laboratory measures of intake, neutral detergent ®ber (NDF) concentration and particle-size reduction index (PSRI), are being used in plant breeding programs. The objective of this study was to determine the relationship among...

mine which selection criteria will have the greatest impact on animal performance without detrimental effects Voluntary intake is often the greatest limitation to animal perforon agronomic traits. Plant breeders must evaluate large mance. Two different laboratory measures of intake potential were used as selection criteria in four smooth bromegrass (Bromus inermis numbers of individual plants, ...

A field experiment was conducted to evaluate the effects of two nitrogen levels (N: 0,100 kg ha -1 ) and four phosphorus levels (P: 0, 60, 90, 120 kg P2O5 ha -1 ) on smooth bromegrass (Bromus inermis Leyss.) seed quality by measuring germination, mean germination time (MGT), protein and phosphorus contents, acid phosphoesterase (APT) and antioxidant enzymes activities, hydrogen peroxide (H2O2) ...

Mixtures of legume and grass are used worldwide to gain advantages in forage production ecological maintenance. However, competition for nutrients by legumes mixtures has not been fully explored. The aim was determine how the proportion affected nutrient mixtures. Treatments included two species combinations five sowing ratios. Competitive ratios (CR) lucerne nitrogen (N) phosphorus (P) over gr...

The objective of this research was to determine the relationships between the morphological development and in situ ruminally degradable protein (RDP), ruminally undegradable protein (RUP), and microbial protein of two cool season grasses (intermediate wheatgrass and smooth bromegrass) and two warm season grasses (switchgrass and big bluestem). The initial growth of grass tillers grown near Mea...
