An in situ study (Exp. 1) using 4 ruminally cannulated steers (343 ± 11 kg of BW) in a completely randomized design was used to compare ruminal degradation characteristics of low-quality cool-season (C3; Kentucky bluegrass straw; Poa pratensis; 6.3% CP; DM basis) and warm-season (C4; tallgrass prairie; 5.7% CP; DM basis) forage. Four ruminally cannulated steers (252 ± 8 kg of BW; Exp. 2) and 4 ...

This study aims to estimate the degradation process of polylactide (PLA) in natural aqueous environments. The biological PLA took place Baltic Sea and pond over a period 1 16 months. characteristic abiotic parameters both environments were monitored during incubation time, their influence on was discussed. changes weight, chemical structure, mechanical properties surface morphology investigated...

Plastic waste disposal is a significant environmental concern due to its low degradability and management practices, especially in developing countries. recycling considered the most effective method, which minimizes impacts. This paper discusses use of poly(ethylene terephthalate) (PET), high-density polyethylene (HDPE), polypropylene (PP) plastic as aggregates concrete industry by incorporati...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

the aim of this work was to investigate the effect of silica coating on bioactivity and biodegradability of hydroxyapatite. in this purpose, we firstly attempted to synthesis hydroxyapatite (ha) nanoparticles and its silica coated (si-ha) sample in collagen matrix using calcium chloride, sodium phosphate and sodium silicate. characterization of the sample was carried out using fourier transform...

effect of electron beam irradiation on degradability coefficients and ruminal- postruminal digestibility of dry matter and crude protein of soybean meal, canola meal and lathyrus sativus seed, irradiated at doses of 50, 100 and 150 kgy was investigated. ruminal degradability of dry matter and crude protein was determined by in situ method using two cannulated holstein heifers. ruminal- postrumi...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

introduction: pragmates australis (pa) (common reed) is a riverside perennial grass found in wetlands throughout temperate and tropical regions of the world. pa grows in many wetlands around rivers in iran. animal feed restriction is the main problem of iranian animal production systems and this feed resource can be fed to native livestock especially in rural areas. ensiling pa could improve it...

The effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (DM) and nutrient digestibility of corn silage wereexamined. Whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: Propionibacterium acidipropionici plus L...
