Following the extraction of oil for biodiesel production, oilseed press cakes are high in fat. As the dietary supplementation of fat is currently considered the most promising strategy of consistently depressing methanogenesis, it follows that oilseed press cakes may have a similar potential for CH4 abatement. As such, this study aimed to characterise the nutritive value of several oilseed pres...

The present study was conducted to measure the flow of microbial and nonmicrobial N fractions entering the omasal canal of lactating dairy cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated Finnish Ayrshire dairy cows were fed, in a 4 x 4 Latin square design, grass-red clover silage alone or supplemented with (on DM basis) 5.1 kg/d of barley, ...

Intercropping legume with cereal is an extensively applied planting pattern in crop cultivation. However, forage potential and the degradability of harvested mixtures from intercropping system remain unclear. To investigate the feasibility of applying an intercropping system as a forage supply source to ruminants, two consecutive experiments (experiments 1 and 2) involving a field cultivation t...

Doepel, L., Montgomery, J. E., Beauchemin, K. A., King, J. R. and Acharya, S. N. 2012. Ruminal degradability and wholetract digestibility of protein and fibre fractions in fenugreek haylage. Can. J. Anim. Sci. 92: 211 217. The purpose of this study was to evaluate the digestibility of fenugreek forage compared with alfalfa in dairy cows. Alfalfa and two genotypes of fenugreek, Quatro and F70, w...

The hydroxyl radical induced decomposition of sulfonamide type antibiotics in dilute aqueous solutions was studied by a wide variety of analytical techniques. The degradation products were identified by LC/MS-MS, GC-MS, and ion chromatography. A new LC/MS-MS multiple reactions monitoring (MRM) database was set up for further identification purposes. ICP-MS, COD, BOD and TOC measurements were us...

introduction recently, considering the fact that access to high quality feed stuffs is limited, using agricultural by-products in animal nutrition has taken to consideration. effective use of these products as alternative energy source for ruminant feeding is important for economical and environmental reasons. major limitation for using agricultural by-products as ruminant feed stuffs is their ...

The objective of this study was to determine the chemical composition, in situ rumen Dry Matter (DMD) and Organic Matter Degradability (OMD48) of Apple tree leaves. In this study, Apple tree leaves were collected from the different parts of East Azerbaijan province. Chemical composition including Dry Matter (DM), Crude Protein (CP), crude Ash (Ash), ether extract, Neutral Detergent Fiber (NDF),...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...

Feeding cereal grain to cattle is common practice for optimal beef and milk production. High concentrations of starch other soluble carbohydrates may cause acidosis. Information on the effect processing protein degradability in rumen are scarce. This study was determine ruminal degradation patterns grains steam pelleting crude (CP) rumen. The pattern dry matter (DM), starch, CP ground pelleted ...

The purpose of this study was to investigate the optimum proportion sorghum straw and ammoniated wheat in vitro vivo apply ruminant diets. One-factor two-factor experimental designs were used tests, with different ratios (S:AWS) 2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2 measure total gas production, CH4 dry matter degradability (IVDMD), organic (IVOMD) fermentation parameters. Additionally, nylon bag t...
