Protein Degradability

A study was conducted to determine the effects of lignosulfonate and heat treatment of canola meal on protein degradability, and to evaluate whether feeding treated canola meal to nursing beef calves enhances preweaning growth. Four supplements were formulated to contain 31% crude protein (CP) using either: (1) untreated canola meal (UTC), (2) heat-treated canola meal (HTC; 100 °C for 1 h), (3) lignosulfonate-treated canola meal (LTC; 5% calcium lignosulfonate and 100 °C for 1 h), or (4) corn distillers' dried grains (DDG). Degradability of canola meal CP was reduced significantly from 55.1% (measured in sacco) to 43.2% by heat, and to 26.7% by lignosulfonate treatment. One hundred and three nursing crossbred calves were given access to either no supplement (control) or one of the four supplements. Weight gain (kg d−1) increased (P < 0.05) from 0.90 for the control to 1.05 for calves fed DDG, and further increased (P < 0.05) to 1.16, 1.16 and 1.18 for calves fed UTC, HTC, and LTC, respectively. Consequently, calves fed canola meal gained 30.8 kg more (P < 0.05) than those fed control, and 12.8 kg more (P < 0.05) than those fed DDG. The performance of suckling calves during the grazing season and body condition of their dams were enhanced by offering canola-based creep feeds. Although degradability of canola meal CP was substantially lowered by lignosulfonate treatment, calf performance was not further enhanced by feeding treated canola meal.

The heat treatment of whole soybeans was investigated, with consideration for oven temperature, process time and the initial moisture content of the beans, with a view to optimizing the removal of the toxic factors and enhancing the feed utilization of the soybean. Two purified diets equal in both crude protein level and classical metabolizable energy level were used. One of the diets consisted of ground whole soybeans (both heat treated and raw), whereas the other diet, containing commercial soybean meal as the only source of protein, provided the control for the tests. Male, White Leghorn cockerel chicks were selected on a weight basis and randomized in battery pens. The experimental treatments were assigned at random to pens and the chicks were provided feed and water ad libitum. Three experiments were conducted using soybeans with initial moisture of 10, 12.5 and 16% and heat treatment for 10, 5 and 3 minutes in a still-air oven within a temperature range of 149–246 C. Certain combinations of time and temperature not only promoted weight gains and feed efficiencies superior to those of the commercial diet, but also resulted in minimal pancreatic hypertrophy. The data obtained reaffirmed that a critical quantity of heat is required to deactivate the toxic factors and to ensure maximum nutritive availability.

The aim of this study was to determine the effect of heat treatment alone or in combination with the addition of lignosulfonate (LSO3) on canola cake protein, lysine, and methionine degradation in the rumen. Cold-pressed canola cake was left untreated, heated at 90, 110, 130, or 150 °C, or processed with 5% of LSO3 (in dry matter) and then heated. Effective rumen degradability of crude protein (CP), lysine, and methionine was less for treated than untreated canola cake (P < 0.05) and decreased with increased temperature of heating, but particularly when canola cake was heated at 150 °C (quadratic, P < 0.01). In general, effective rumen degradability of CP, lysine, and methionine was less for canola cake heated at 130 °C in combination with LSO3 compared with canola cake heat treated only (quadratic × LSO3 interaction, P ≤ 0.07). Results of this study indicate that high temperature heating (130 °C or greater for 60 min) may be necessary to protect canola cake protein from degradation in the rumen, and the combination of heat treatment and LSO3 may be more effective in protecting canola cake protein, lysine, and methionine from degradation in the rumen than the use of heat treatment only.

The effect of adding 5% calcium lignosulfonate (LSO3) and heat to canola screenings on in situ ruminal and intestinal dry matter (DM) and crude protein (CP) disappearance in Holstein cows was investigated. Treatments consisted of untreated canola screenings, canola screenings that had been heated to 100 °C for 30 or 60 min and canola screenings that had 5% (wt wt−1) LSO3 added and were subsequently heated at 100 °C for 0, 30 or 60 min. Results indicate that treatment of canola screenings with 5% LSO3 and heated to 100 °C for 60 min was effective in reducing rumen degradation of DM and CP with a corresponding increase in disappearance in the lower gastrointestinal tract when compared to untreated and heat-treated canola screenings.

The effect of heat treatment on canola meal (CM) dry matter (DM) and nitrogen (N) degradability in the rumen and digestion in the small and large intestines and total digestive tract of steers was determined. CM was moist-heat-treated at 127 °C for 15 and 45 min. The degradation of DM and N was estimated using small nylon bags in the rumen for 0.1, 4, 8, 12, 16, 24, 48 and 72 h. The mobile bag technique with an in vitro incubation in an acid-pepsin solution was used with a separate set of bags to estimate the digestion of each nutrient in the small and large intestines as well as the total digestive tract for rumen incubation times of 8, 16 and 24 h. Chemical analysis of heated CM showed a significant reduction in soluble N, sucrose and glucosinolate content while the concentration of ADIN increased. Treatment significantly reduced the degradation of DM and N in the rumen while the digestibility of DM and N in the small intestine increased with both treatments proportional to the decreased rumen degradation. Heat treatment had no effect on DM and N digestibility at the large intestine site. Total tract disappearance of DM and N were not affected by 15 min heating; however, after 45 min heating, DM and N disappearances were reduced. Moist heat treatment was effective in reducing rumen disappearance of CM nitrogen while it increased the N digestion in the small intestine.

The effect of heat treatment and germination on the proximate and mineral composition, HCH, tannins, phytic acid and the in vitro protein digestibility of Mucuna utilis seeds were studied. The raw seeds had a protein content of 35.4%, 7.7% crude fibre, 3.2% ether extract, 5.8% ash and 47.9% carbohydrates on a dry matter basis. The germinated and dehulled seeds had 40.5% crude protein 2.2% crude fibre, 3.4% ether extract, 7.0% ash 47.0% carbohydrates, while the heat -treated seeds had 34.4% crude protein, 11.9% crude fibre, 3.3% ether extract, 9.4% ash and 41.1% carbohydrates. Potassium and iron were the most abundant minerals while the least were sodium and copper. Germination caused a reduction in the levels of all minerals while heat treatment also caused a reduction in the levels of the minerals but with exception of Ca, Mg and Zn. Processing caused a reduction in all the levels of anti-nutritional factors assayed. The in-vitro protein digestibility of the raw seeds was 89.4%; 91.7% for the heat-treated seeds and 76.0% for the germinated seeds.

Abstract Characterizing fiber into fermentable and unfermentable fractions may enhance the accuracy of estimating DE and ME energy content in fiber-rich ingredients. Therefore, the objective of this study was to analyze the concentrations of NDF, representing both the fermentable (fNDFom) and unfermentable (uNDFom) portions among sources of corn distillers dried grains with solubles (DDGS), and determine their relative contributions to DE and ME content. The concentrations of DE and ME, as well as apparent total tract digestibility (ATTD) of GE, were measured in a previous experiment. Samples of DDGS (0.5 g) were mixed with fecal inoculum and incubated for 8, 12, and 72 h. The ash corrected NDF (NDFom) content of DDGS residues at each time point was determined. The fNDFom increased with fermentation time of 8 h (21.6%), 12 h (29.0%), and 72 h (68.6%). The ATTD of GE increased as the uNDFom decreased at 8 h (uNDFom8; R2 = 0.83; P &lt; 0.01) and 72 h (uNDFom72; R2 = 0.83; P &lt; 0.01). Likewise, ME content of DDGS increased as uNDFom72 decreased (R2 = 0.59; P &lt; 0.01). The best-fit DE equation was DE (kcal/kg DM) = 2,175 – 3.07 × uNDFom8 (g/kg, DM) – 1.50 × uNDFom72 (g/kg, DM) + 0.55 × GE (kcal/kg DM) (R2 = 0.94, SE = 36.21). The best-fit ME equation was ME (kcal/kg DM) = 1,643 – 2.31 × uNDFom8 (g/kg, DM) – 2.54 × uNDFom72 (g/kg, DM) + 0.65 × GE (kcal/kg DM) – 1.42 × crude protein (g/kg DM) (R2 = 0.94, SE = 39.21). These results indicate that in vitro unfermented fiber is negatively associated with GE and NDF digestibility, and therefore, is a good predictor of DE and ME content in corn-DDGS.

Abstract Although heat treatment affects digestibility of amino acids in feed ingredients, there is less information as to whether such an effect also applies to minerals. Therefore, the objective of this research was to investigate the effects of heat treatment on apparent (ATTD) and standardized total tract digestibility (STTD) of P in dry extruded-expelled soybean meal (DESBM), solvent-extracted canola meal (SCM), and expeller-extracted canola meal (ECM) fed to growing pigs. A total of 36 pigs (19.0 ± 1.0 kg) were assigned to 1 of 6 diets in a completely randomized design to give 6 replicates per diet. Pigs were individually housed in metabolism crates for 12 d, including 7 d for adaptation and 5 d for total collection of feces. The experimental diets were formulated to contain non-heated or heat-treated DESBM, SCM, and ECM as the sole source of P. Pigs were offered their daily ration at 2.8 times their maintenance energy requirement. Data were analyzed as a 3 × 2 factorial arrangement using the PROC MIXED of SAS with ingredients, heat treatment, and their interaction; however, no interaction was observed for any variable. Pigs fed the DESBM diet had a higher (P &lt; 0.05) ATTD and STTD of P than pigs fed SCM and ECM diets. The ATTD and STTD of P in heat treated samples were higher (P &lt; 0.05) than in non-heated samples. In the heat-treated samples, the values of STTD of P were 49.4, 23.2, and 25.8% for DESBM, SCM, and ECM, respectively. Respective values for STTD of P in non-heated DESBM, SCM, and ECM were 48.5, 20.2, and 22.5%. The ATTD of Ca in non-heat-treated samples was lower (P &lt; 0.05) compared to the values for heat-treated samples. In conclusion, heat treatment increased ATTD and STTD of P in DESBM, SCM, and ECM fed to growing pigs.

A study was conducted to determine the effects of stage of processing of canola seed on chemical characteristics and in vitro crude protein degradability (IVCPD) of canola products. Processing stage prior to oil extraction had no effect on nutrient composition or IVCPD of canola products. Prepressing of cooked flaked seed reduced IVCPD and increased fiber and crude protein (CP) levels of presscake relative to canola seed (P < 0.05). Heating in the desolvetizer-toaster increased neutral detergent fiber (NDF) content and reduced CP solubility and IVCPD of canola meal relative to solvent-extracted meal (P < 0.05). Acid detergent insoluble CP of canola products was not affected by stage of processing. It was concluded that major changes in protein composition and degradability took place as a result of heating in the desolventizer-toaster stage.
