Abstract:

Many markers can be used in digestibility assays for swine, but needs to be evaluated before its use. An assay was carried out with the objective of measuring the coefficients of ileal apparent (CIAD) and standardized digestibility (CISD) of amino acids in meat and bone meal for swine using different markers. Eight crossbred barrows were equipped with T-cannulas in the distal ileum. Four animals received a free protein diet and another four received a diet containing meat and bone meal as the only protein source in the diet. The treatments consisted in evaluating the chromic oxide, acid-insolu

Abstract:

Chromic oxide concentration was determined spectrophotometrically (440 nm) on 10 to 100-mg samples of feeds and feces following a procedure involving oxidation with chlorine bleach. Average coefficients of variation and internal recoveries of added chromic oxide were < 2% and > 96%, respectively. The procedure is simpler and safer than other procedures based on strong oxidizing acids. Key words: Chromic oxide, feed, feces, analysis

Abstract:

Chromic sesquioxide is an indigestible marker commonly used in grazing trials. Experiments were conducted to establish a procedure for preparing standard calibration curves for determination of low levels of chromium (Cr) in feces from animals dosed with Cr markers. The calibration curves (prepared using blank feces) were compared with feces-free standards to evaluate the effect of feces on the results. The presence of digested feces reduced the absorption of Cr by 0–5%. The slopes of the calibration curves prepared by digesting the Cr standards with feces were 79–90% of the slopes of standard

Abstract:

Studies were carried out to determine the digestibilities of amino acids (AA) and energy in five sources of rice bran (RB). The sources of RB included two that were not further processed, a defatted, an extruded, and an atypical source of RB consisting mainly of starchy endosperm referred to as polish. Six barrows, average initial body weight 36.5 kg, were fitted with a simple T-cannula at the distal ileum, and fed six diets according to a 6 × 6 Latin square design. The five RB-containing diets contained 53.8% corn, 19.9% soybean meal, and 23.1% RB. The basal diet contained 71.0% corn and 26.3

Abstract:

The aim was to test additivity of apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids (AAs) in mixed diets for Ross 308 broiler chickens. Two hundred and eighty-eight, 20-d-old male broiler chickens were assigned to one of six diets, with six birds per cage using a randomized complete block design. The diets consisted of a nitrogen-free diet, three diets containing corn, soybean meal (SBM), and corn distillers dried grains with solubles (CDDGS) as the sole source of nitrogen, respectively, and two mixed diets containing corn, SBM or CDDGS.

ABSTRACT: Three experiments were conducted to determine the nutritional composition of tilapia filleting waste meal (TFWM) for pigs in the initial phase. In the first experiment, the chemical composition and the values of digestible and metabolizable energy of TFWM were determined using 10 pigs (15.10 ± 0.74 kg), distributed in cages for metabolic research (2 treatments X 5 replicates). The TFWM replaced 20% of the reference diet based on corn and soybean meal. In the second experiment, the ileal digestibility coefficients of amino acids present in TFWM were determined, using chromic oxide as

Abstract:

Trials were conducted to study the effect of dietary fibre on performance and nutrient digestibility in growing rabbits. The basal diet was supplemented with 12% cellulose, pectin, lignin, or alfalfa, in four different treatments. Twenty-four 4-week-old Californian male rabbits were randomly allocated into four groups and placed in individual cages. The lignin supplement severely affected both feed intake and performance, pectin second, with dietary cellulose having the least effect. Dietary lignin significantly decreased the digestibility of crude protein, gross energy and dry matter content

Abstract Two experiments were conducted to test the hypothesis that different watering options affect the standardized ileal digestibility (SID) of amino acids (AA), apparent total tract digestibility (ATTD) of dry matter (DM) and gross energy (GE), and concentration of net energy (NE) by growing pigs. A corn-soybean meal-based diet was used in both experiments. There were 3 treatments: 1) dry feeder plus a water nipple located outside the feeder, 2) wet-dry feeder with the water nipple inside the feeder, and 3) combined system with a water nipple both inside the feeder and also an outside nip

An experiment was conducted to determine the effect of oil sources with differing degrees of fatty acid saturation on endogenous losses of fat (ELF) and fatty acids (ELFA) in growing pigs, in which endogenous losses were estimated by two methods. Sixty-eight growing barrows (initial body weight 31.13 ± 4.44 kg) were randomly allotted to a completely randomized design with 17 diets. Sixteen added-oil diets were formulated by adding four levels (2%, 4%, 6% and 8%) of palm oil (PO), soybean oil (SBO), flaxseed oil (FSO) and rapeseed oil (RSO) to a diet poor in fat, respectively.
