A set of prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) of individual ingredients and diets used in the poultry feed industry was evaluated. The AMEn values of three energy ingredients (maize, sorghum and defatted maize germ meal), four protein ingredients (soybean meal, maize gluten meal 60% crude protein, integral micronized soy and roasted whole ...

Marine algae have recently emerged as a new exciting source of biofuel. Our objective was to determine effect of supplemental defatted algal biomass from biofuel production on biochemical indicators of protein metabolism in plasma of weanling pigs. A total of 27 weanling pigs (BW = 10.69 ± 0.22 kg) were divided into 3 groups (n = 9/group), and fed a corn-soybean meal basal diet (BD), the BD plu...

This experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (NaB and CaB) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. Two hundred and sixty day old broilers of male Ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. The experiment was carried out in a comp...

Two experiments involving a total of 581 crossbred pigs weaned at 23 +/- 2 d of age evaluated 1) the efficacy of two diets that contained milk products during the initial 14 d postweaning and 2) the effect of coconut oil or soybean oil additions to swine starter diets. In Exp. 1, postweaning performance responses of pigs fed a control corn-soybean meal-dried whey (C-SBM-DW) diet without added f...

The standardized ileal digestibility (SID) of CP and AA was evaluated in soybean (Glycine max) meal, sunflower (Helianthus annuus) meal, rapeseed cake, and field pea (Pisum sativum) using 10 pigs and in lupine (Lupinus angustifolius) using 7 pigs. Pigs were fitted with either a T-cannula or a steered ileocecal valve-cannula. Diets contained 170 to 186 g CP/kg DM. Endogenous losses of CP and AA ...

Two experiments were conducted to investigate the use of sorghum, cottonseed meal and millet in broiler diets and their interaction when they are used simultaneously. In Experiment 1, a corn-soybean meal control diet was compared with eight experimental treatments based on low tannin sorghum (S30, S45 and S60), cottonseed meal (CM15, CM40) or both ingredients included in the same diet (S30/CM40...

Ten ruminally cannulated lactating Holstein cows that were part of a larger trial studying the effects of feeding different proteins on milk production were used in a replicated 5 x 5 Latin square to quantify flows of microbial and rumen-undegradable protein (RUP) in omasal digesta. Cows were fed total mixed rations containing (dry matter basis) 44% corn silage, 22% alfalfa silage, 2% urea, and...

An experiment was conducted to examine the effects of adding microbial phytase (Natuphos) on the performance in broilers fed a phosphorus-adequate, lysine-deficient diet. A wheat-soybean meal-sorghum-based diet, containing 1.00% lysine and 0.45% nonphytate phosphorus, was supplemented with L-lysine monochloride to provide 1.06, 1.12, or 1.18% lysine or with 125, 250, 375, 500, 750, or 1,000 phy...

In this study the effects of supplemental crystalline niacin on sow reproduction and sow and litter performance were evaluated using 240 litters produced by 67 sows. A basal 12.80% CP corn-soybean meal-oat diet was supplemented with 0 or 33 mg of crystalline niacin/kg during gestation and lactation. The sows were grouped to equalize initial BW and parity among the two treatment groups. Each sow...
