The purpose of this study was to increase the nutritional value two raw materials (soybean straw and ryegrass hay), in order propose use as feed for ruminants. Different technologies were used develop animal feed: addition proteins, Spirulina platensis biomass, solid state fermentation by Aspergillus niger, encapsulation microalgae biomass (capsules with xanthan gum chitosan), well control test...

Samples of feed ingredients were collected from poultry feed mills in the United States and Canada: corn (133), soybean meal (114), corn distillers dried grains with solubles (DDGS; 89), bakery by-product meal (95), wheat (22), wheat middlings (31), canola meal (21), and wheat shorts (15). The samples were assayed by standard wet chemical techniques for CP, fat, neutral detergent fiber (NDF), a...

Pelibuey sheep is the main breed in the tropical and subtropical regions of Mexico, and high demand of sheep meat has favored the finishing of lambs in feedlots with diets containing high levels of grains. The objective of this study was to evaluate the effects of exogenous enzymes (EE) and application method on nutrient intake and digestibility and performance of growing Pelibuey lambs. Treatm...

The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral Detergent Fiber (NDF), a...

the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...

in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

studying the autecology of range plants provides the basic information on their ecological requirements, cultivation methods and the interactions with the prevailing environment. such information is necessary for a proper range management. some ecological characteristics of astragalus arpilobus kar. & kir., were studied in the winter rangelands of northern khorasan province. it was naturally gr...

efficient use of agricultural wastes due to their recycling and possible production of cost effective materials, have economic and ecological advantages. a biological method used for degrading agricultural wastes is a new method for improving the digestibility of these materials and favoring the ease of degradation by other microorganisms. this research was carried out to study the possible bio...
