Experiments were conducted to determine the effects of supplementing chopped ryegrass hay with 0, 5, 10, or 20% fat coated with ruminal bypass protein (Prolip on ruminal digestion by cows and nutrient digestibility by sheep. Ruminal disappearances of DM, ADF, and NDF were measured by the in sacco technique using a cannulated cow. Degradation of DM, ADF, and NDF was not affected by protected fat...
A meta-analysis was performed to determine the influence of cereal grain type and corn grain harvesting and processing methods, dietary starch, rumen-digestible starch, and forage NDF concentrations on intake, digestion, and lactation performance by dairy cows using a data set comprising 414 treatment means from 102 peer-reviewed journal reports from 2000 to 2011. Categories for corn processing...
Fats and oils are chemically diverse group of compounds, which have the highest energy density among all macro nutrients. Besides having high caloric values, they are major sources of essential fatty acids (Ω-3 and Ω-6), fat soluble vitamins (A, D, E and K) and lecithin. Moreover, supplementation of fats and oils to poultry rations increases the metabolizable energy of the total ration, the cal...
Data from six experiments (two with dry cows) were used to predict partitioning of gross energy to CH4 in Holstein cows using selected independent variables, some of which were intercorrelated, and a stepwise backward elimination regression procedure. Methane outputs ranged from 3.1 to 8.3% (mean 5.5) of gross energy intake for 134 dry cow balance trials and from 1.7 to 14.9% (mean 5.2) of gros...
The ileal energy contribution of protein, starch, and fat in response to 2 exogenous enzyme combinations was studied in 2 digestibility assays with 21- (experiment 1; 432 birds) and 42-d-old (experiment 2; 288 birds) Ross 308 broiler chickens. A 2 × 2 × 3 factorial arrangement of treatments with 2 base grains (corn or wheat), without or with high fiber ingredients (corn distillers dried grains ...
Whereas dietary fibers are well recognized for nutritional management of human health issues, fiber is also known to be one of the dietary factors potentially affecting digestive use of dietary proteins. As a staple food, potato (Solanum tuberosum) may be a significant dietary fiber source. The objective of this study was to examine effects of dietary supplementation of six potato cultivar-geno...
The apparent digestibility of energy, protein, fat and non-starch polysaccharides (NSP) of low and high dietary fibre (DF) mixed diets were studied in three series of experiments with man and the rat. Low DF diets were used as control diets in each experimental series and the DF level was increased by adding fruits and vegetables (Study 1), citrus fibre concentrate (Study 2) and insoluble barle...
five species of dominant halophyte plants including: salsola griffithii, chenopodium album, aeluropus logopoidies, alopecurus textillis and cardaria draba were sampled from sistan region at their late vegetative stage. the collected samples were dried at room temperature and ground, and their chemical components including: dry matter, organic matter, ash, crude protein, crude fat, as well as ce...
The objectives of these studies were to predict the effects of roasting and extrusion temperatures of whole soybeans (SB) on intestinal protein digestibility in cattle. Intestinal digestibility was assessed with a two-stage in vitro or in situ ruminal incubation/precision-fed cecectomized rooster bioassay. In Exp. 1, whole SB (raw SB or SB roasted to 141, 149, or 157 degrees C exit temperature ...
