The apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients were evaluated in 2 commercially available products: wheat (Triticum aestivum) wet distillers grain with solubles (WDGS) and wheat dried distillers grain with solubles (DDGS). Two diets included (DM basis) 50% basal diet with either 50% WDGS (W) or 50% DDGS (D). The basal diet included corn (Zea ma...

Twenty-four Merino lambs were allocated to three dietary treatment groups determine the effects of a starch and protein binding agent heat stress on methane (CH4) emissions rumen parameters. The diets wheat-based diet (WD), 2% Bioprotect™ (Bioprotect™, RealisticAgri, Rutland, UK) treated (BD), maize-based (MD) for 3 periods 1-week duration. During Period 1 (P1) maintained under thermoneutral co...

Two experiments were performed to evaluate the effects of different levels of supplementation with a 50:50 (as-fed) mixture of molasses:crude glycerol on animal performance, total tract digestibility of nutrients, and ruminal in situ degradability of nutrients in beef heifers and steers consuming Tifton 85 Bermuda grass (Cynodon spp.) hay. For Exp. 1, 24 Angus crossbred heifers (380 ± 31 kg BW)...

Two experiments were conducted to determine the effects of supplementing ruminally degradable intake protein (DIP) or ruminally undegradable intake protein (UIP) on N balance (Exp. 1; n = 6 wethers; initial BW = 48.7 +/- 4.6 kg) and site and extent of digestion (Exp. 2; n = 5 wethers; initial BW = 36.9 +/- 3.1 kg) in whiteface wethers consuming (as-fed basis) 69% blue grama and 31% love grass h...

The study addressed the importance of yeast (Saccharomyces cerevisiae) viability for reducing the incidence of subacute ruminal acidosis (SARA) and improving total tract nutrient digestibility in beef heifers. Six ruminally cannulated beef heifers (680 ± 50 kg BW) were used in a replicated 3 × 3 Latin square design and were fed a diet consisting of 40% barley silage, 10% chopped grass hay, and ...

These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

Seventy-two growing pigs (initial BW: 18.0 ± 1.6 kg) were used to determine the apparent total tract digestibility (ATTD) of P and Ca and the standardized total tract digestibility (STTD) of P in 8 different sources of meat and bone meal (MBM) and to develop equations to predict digestibility of P and Ca in MBM. Pigs were housed individually in metabolism cages and were randomly allotted to 9 d...

An experiment was conducted to determine the effect of graded levels of β-glucanase supplementation to barley (Hordeum vulgare)-based diets on the digestibility of DM, GE, N, and AA for growing-finishing pigs. Eight pigs (initial BW: 53.3 ± 3.2 kg) were each fitted with a simple T-cannula at the distal ileum and allotted to a replicated 4 × 4 Latin square design with 4 diets and 4 periods in ea...

and Implications The aim of this study was to test if further grinding of corn DDGS is advantageous in terms of apparent total tract digestibility (ATTD) of DM, GE, nitrogen (N), and NDF in growing and finishing pigs. It was also tested to determine if ATTD was different between hammermill and roller mill grinding methods. There were 3 diets. Each diet consisted of 51% corn ground at 500 micron...

One hundred twenty medium-frame crossbred steers (364 kg) were used in a 106-d feedlot trial to compare the feeding value of Condor, a hulless barley (HB), with Leduc, a conventional covered barley (CB). Dietary treatments consisted of a finishing diet containing 77% grain (DM basis) as 1) steam-flaked corn (SFC); 2) dry-rolled HB (DRB-H); 3) steam-flaked HB (SFB-H); 4) dry-rolled CB (DRB-C); a...
