The present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by Trichoderma reesei and Trichoderma viride. In vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. The cultivation of T. reesei and T. viride on orange pe...

1. The absorption of zinc in humans from composite meals, was determined by extrinsic labelling of the meals with 65Zn and measurement of the whole-body retention of the radioisotope. 2. Low-Zn (mean 25 mumol) chicken meals with 150 g white bread or 225 g potatoes, carrots, turnips, cabbage or green peas were studied. The effect of a beet-pulp-fibre preparation used as a breakfast cereal, in br...

The effect of time and pressure on the selective extraction of sugar beet pectin using steam pre-treatment on unprocessed Sugar Beet Pulp was evaluated using a design of experiments approach. This process gave the highest solubilisation of pectin oligomers at a relatively low pressure and longer time (5Bar, 24min), whilst leaving the majority of the cellulose fraction intact. This method of ste...

A repeated 4×4 Latin square design was conducted with eight ileal cannulated castrates to examine the effect of source of starch and fiber on nutrient balance and energy metabolism. Pigs were fed on one of the four experimental diets: Control diet (C) mainly based on cooked rice; and diets P, S and W with the inclusion of either raw potato starch, sugar beet pulp or wheat bran supplementation, ...

Six wethers were used in a replicated 3 x 3 Latin square to study the fermentation quality and nutritive value of total mixed ration (TMR) silages that included wet coffee grounds (WCG). The TMR were prepared using a commercial compound feed, timothy hay, alfalfa hay, dried beet pulp, and a vitamin-mineral supplement in a ratio of 36.5:30:20:12:1.5, respectively, on a DM basis, with timothy hay...

In order to enhance knowledge of the nutritive value of ostrich feeds, the in vitro gas production technique was used. Five feeds (corn silage, CS; alfalfa hay, AH; barley, BG; soybean meal, SM; beet pulp, BP) were weighed (~ 1g) in quadruplicate in 120 ml serum flasks and incubated at 39 °C with 75 ml of anaerobic medium and 4 ml of reducing solution. A pool of caecal contents obtained at slau...

this experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. a completely randomized design with six treatments and six replicates was used.the six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

This experiment was conducted to determine whether increasing the net energy (NEL ) of a total mixed ration (TMR) with mainly unsaturated fat from corn distillers dried grains with solubles (DDGS) vs. rumen inert (RI)-saturated fat has similar impacts on animal performance. The experiment was an incomplete Youden square with three treatments and four 28-days periods, completed on a large commer...

In Exp. 1, soybean hull samples were obtained from nine sources across the United States and analyzed for nutrient content to determine their suitability for inclusion in dog diets. Compositional data revealed variation in both the amount of total dietary fiber (TDF; 63.8 to 81.2%) in the soybean hulls and the ratio of insoluble:soluble fiber (5.0:1 to 15.4:1). Crude protein content varied wide...

introduction ensiling is one of the common preserving methods for forage or other organic materials. in this method, organic matters were preserved by proving an aerobic condition and then by reducing the ph with increasing acids production (mainly lactic acid). some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in en...
