An important objective is to identify nutrients or dietary factors that are most critical for advancing our knowledge of, and improving our ability to predict, milk protein production. The Dairy NRC (2001) model is sensitive to prediction of microbial protein synthesis, which is among the most important component of models integrating requirement and corresponding supply of metabolizable protei...

effects of summer savory (satureja hortensis l.) dry powder (ssdp) and essential oil (sseo) on performance, ruminal fermentation and blood metabolites were assessed using 20west azerbaijan native kids (16±1.94 kg initial live weight) in a random block design with 5 treatments (4 replicates per treatment) over a 13-week period. treatments were: i) basal diet without additive (control), ii): basa...

paste of big head carp fish was prepared based on three formulas and was selected base on organoleptic properties test results. the product was then divided into three portions of: sample 1 (control), sample 2 (containing 0.01% butylated hydroxy anisole bha antioxidant) and sample 3 (containing 0.02% antioxidant bha). to determine the shelf life, the samples were frozen and kept in cold storage...

Molecular distillates of butter oil consisting of the four most volatile 2.5% cuts (obtained by a redistillation of the first 10% cut), the next most volatile 40% cut, and the 50% residue obtained from 777 pounds of oil were subjected to fractionation by adsorption and gas-liquid chromatography. Only the most volatile 2.5oj, cut, which contained 10% unsaponifiable matter, was examined in detail...

The present study was conducted to evaluate the effect of low-dose gamma irradiation (0, 1, 3 and 5 kGy) on fatty acid composition of Rainbow trout (Oncorhynchus mykiss) fillet. Among all of the fatty acids, oleic acid (C18:1) (with mean 33.50±3.02 g/100 g fatty acids) and myristoleic acid (C14:1) (with mean 0.41±0.26 g/100 g fatty acids) were the most predominant and the lowest fatty acids in ...

Polyhydroxyalkanoates are known to be temporarily stored by microorganisms in activated sludge, especially in anaerobic-aerobic processes. Due to the problems resulted from the disposals of plastic wastes and excess sludge of wastewater treatment plants, the production of polyhydroxyalkanoates by treating activated sludge and determining the effect of process variables were the main issues of t...

Growth, cecal volatile fatty acids, mineral profile of plasma, liver weight and gastrointestinal weights were measured in rabbits fed isonitrogenous, equicaloric diets containing 3, 6, 9 or 12% dietary crude fiber from either alfalfa or Coastal Bermuda grass. Rabbits were fed from 4 to 8 wk of age. Alfalfa diets improved (P less than .05) average daily gain (20.5 vs 11.9 g/d) and livability (67...

In in vitro ruminal fermentation, micronised wood powder is digested to produce volatile fatty acids, but its fermentability is weak. The aim of the present study was to ascertain a suitable pretreatment of micronised wood powder to enhance volatile fatty acid production in vitro. Rumen fluid taken from beef cattle was anaerobically incubated with micronised wood powder. Initially, effects of p...

infant formula has a fatty acid composition that meets the needs of the neonates for unsaturated fatty acids.these fatty acids are of major importance during this period of life in which the brain and retina are developing, and will therefore have an influence upon visual acuity and learning abilities. oxygen reacts readily with unsaturated fatty acids, so that every time these compounds are ha...
