the objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (dm), crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) of ten pasture forage species dominant in the west provinces of iran. duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. the chemical com...

The viability of multistrain cocktails genetically marked strains Listeria monocytogenes and Shiga toxin-producing Escherichia coli (STEC) were separately monitored on slices one brand a commercially produced bresaola (ca. pH 6.7 aw 0.899) during extended storage at refrigeration abusive temperatures. Two 8 g each; ca.10.2 cm wide, ca. 11 long) layered horizontally within nylon-polyethylene bag...

Four rumen and proximal duodenum fistulated non-lactating Holstein cows were used to determine the effect of extrusion at 120 degrees C of whole horse beans (Vicia faba cv Talo) on in vitro nitrogen (N) solubility and in situ degradation of dry matter (DM) and crude protein (CP) in the rumen and intestine. Cows were fed a ration of 30% whole horse beans (WHB) and 70% Italian rye-grass hay. The ...

Veira, D. M., Charmley, L. L., Charmley, E. and Lee, A. J. 2001. The effect of feeding soybean oil to mid-lactation dairy cows on milk production and composition and on diet digestion. Can. J. Anim. Sci. 81: 425–428. Mid-lactation Holstein cows were used to test the effect of feeding 3% soybean oil (SBO) on total mixed ration intake, apparent digestibility, milk production, and milk composition...

We studied the microbial flora in decomposing mangrove leaves in relation to changes in nitrogen and tannin levels, and in penaeid prawn assemblages. Senescent leaves of two mangrove species (Rhizophora apiculata and Avicennia marina) kept in nylon bags, were separately immersed for 80 days in five tanks full of mangrove water. A known amount of decomposing leaves was collected every ten days f...

Traditional food packaging protects food from external contamination, oxygen, water vapour and light. However, newer packaging technologies such as Modified Atmosphere Packaging (MAP) do more than just provide protection from outside influences. The study was conducted to increase the shelf life of paneer by using MAP technique. The paneer samples were packaged in high barrier bags (LLD/BA/Nylo...

During investigations into the volatility of female pheromones of A. walkerae in a Y-shaped olfactometer, engorged conspecific male ticks responded weakly both to female-contacted filter paper discs and to intact females enclosed in nylon bags. In tests in which female-contacted filter paper discs were separated from engorged male ticks by means of a screen, no aggregation was observed. However...

Effects of packaging and irradiation combinations on lipid oxidation, off-flavor, and color changes of raw patties prepared from three pork muscles were studied. Patties were prepared from each of the ground L. dorsi (L. thoracis and lumborum), psoas, and R. femoris muscles of pig, packaged either in oxygen permeable polyethylene bags or impermeable nylon/polyethylene bags, irradiated with an e...

This study was carried out to determine the nutritive value of sun flower meal treated and untreated with 0.5% urea and microwave using nylon bags technique in Gizel sheep. Two fistulaed Gizel sheep with average BW 45±2 kg were used in a complete randomized design. The treatments were as following: A: sun flower, B: sun flower treated with 0.5% urea, C: sun flower treated with microwave. The ru...
