A 15-wk feeding trial was conducted to examine the supplemental effects of Barodon on growth performance, gastrointestinal histology, feed digestibility and innate immunity in olive founder. A basal commercial diet was used as a control and two other diets were prepared by spraying 0.1% or 0.2% of Barodon. Triplicate groups of fish (BW, 145 g) were fed one of the test diets to apparent satiatio...

A total of 360 1-d-old broiler chickens were fed on a diet based on rye and wheat in equal proportions without or with supplementation of increasing levels (0.11, 0.22, 0.44 and 0.88 g/kg) of a technical enzyme preparation containing pentosanase and beta-glucanase activities. In vitro investigations revealed that the enzyme preparation solubilized pentosans, increasing the relative viscosity of...

Pre-ruminant calves were pair-fed a concentrate feed in either liquid form (LC) from a nipple bottle or in dry form (DC). We then studied the effects of these two forms of feed on body weight gain, feed utilization, digestibility, digestive enzyme secretion and volatile fatty acids in the rumen liquor. The live weight gain of calves receiving the liquid concentrate was depressed by 34 p. 100. T...

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...

A sheep digestion trial and two feedlot trials with cattle were conducted to study effects of an ionophore, salinomycin, on nutrient digestibility, ruminal metabolism and cattle performance. In trial 1, addition of salinomycin at 5.5, 11 or 22 ppm to 60% concentrate diets fed to ruminal-cannulated rams had no effect (P greater than .05) on apparent digestibility of dry matter (DM), organic matt...

Thirty-six Merino lambs (8 to 9 wk of age, and 15.3 ± 0.13 kg of initial BW) 1 were used to evaluate the effects of the inclusion of 120 g sugar beet pulp (replacing 2 barley) and of the addition of 20 g sodium bicarbonate per kg concentrate on feed 3 intake, digestibility, animal performance and carcass characteristics in fattening lambs. 4 Animals were housed individually and fed barley straw...

Maize and solvent extracted soybean meal (SBM) were ground through a 2 or 3 mm screen, resulting in “fine” and “coarse” material. The mean particle sizes of fine and coarse feed were 0.62 vs. 0.96 mm (maize) and 0.63 vs. 1.01 mm (SBM). Maize or SBM of either particle size was included in experimental diets at two different levels at the expense of maize starch. Three week old broilers had free ...

The objective of this experiment was to determine the effect of a beta-glucanase-protease enzyme blend product (EBP) on fecal digestibility (FD), apparent ileal digestibility (AID), standardized ileal digestibility, and digestibility in the hindgut of growing pigs. Twelve ileal-cannulated, growing barrows (38.2 +/- 0.5 kg) were housed in individual metabolism crates, blocked by previous feed in...

Ileal digesta were collected via a post-valve-T-caecum cannula from piglets ( lo-15 kg) fed diets based on raw pea or on pea protein isolate (Finale or Frijaune variety). From the determined amino acids (AA) content of feed and digesta, AA apparent digestibility coefficients and proportions of proteins (endogenous, bacterial, dietary) theoretically present in digesta were calculated. Four essen...

1. The abilities of cattle, sheep, goats, equines and rabbits to digest mature timothy (Phleum pratense) hay were compared. Apparent digestibilities were partitioned into true digestibility, metabolic faecal output (MFO) and fibre digestibility. The aid of the study was to determine the relative effects of fermentation site (among groups) and of body-weight (within groups) on the efficiency of ...
