One milliliter of broth was sampled before and after the glucose feeding to determine the concentrations of glucose, ethanol, and acetate.
From d 16 to 21 of each period, DM intake was measured while, from d 22 to 24, ruminal contents were sampled 0, 4, 8 and 12 h after feeding to determine ruminal pH, volatile fatty acids (VFA) concentration, large peptide (LPep), small peptide plus amino acid (SPep + AA), and ammonia N. Statistical differences were declared if P<0.05.
Nymphs attached to mice were removed after 72 hrs of feeding to determine candidate genes expression levels.
Naphtha obtained from Chevron was analysed prior to being used as a feed to determine the hydrocarbon composition.
analysis on the supernatant solution yielded the composition of unreacted monomer mixture, which was used in conjunction with θ and the composition of initial feed to determine the reactivity ratios (r) via an iterative procedure involving a simplex algorithm, yielding AMA(1 MMA(2)r1 = 1.55 ± 0.16, r2 = 0.99 ± 0.19 and AMA(1 VP(2)r1 = 1.408 ± 0.074, r2 = 0.401 ± 0.044.
Chemical analysis was performed on this feed to determine the concentrations of vitamin E. The result showed that the feed contained < 11.98 mg/kg, which is an insignificant amount of dietary supplement (normal horse feed would contain 80 μg/kg vitamin E).
Try sprouting the seeds you feed to determine their quality.
The objectives of this study were to expand the database and determine the intestinal digestibility of rumen undegradable protein (dRUP) of common dairy feeds and to determine the effects of feeding 37.9% wet corn gluten feed on these estimates.
A standardized questionnaire was administered at every study visit by a member of the study team who was not conducting the feeding counseling to determine feeding behaviors in the past 24 hours, past week and since the last visit.
