Residual feed intake (RFI) is a unique measure of feed efficiency (FE) and an alternative to traditional measures. The RFI is defined as the difference between the actual feed intake of a pig and its expected feed intake based on a given amount of growth and backfat. Therefore, selecting pigs with a low RFI (LRFI) results in a more feed-efficient animal for a given rate of growth. Our objective...
This research was conducted to study the nutritive value of Jerusalem artichoke (JA) as animal feed. The aerial part of the JA plant was harvested, at full bloom stage, and then chopped and dried. The chopped JA hay included 0.0, 10, 20, 30 and 40 % of alfalfa hay, used as experimental diets, and tested for in vitro digestibility. In a changeover experiment with Latin square based design the in...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
OBJECTIVE The objective of the study was to determine the effect of fermented spent coffee ground (FSCG) on nutrient digestibility and nitrogen utilization in sheep. METHODS Fermentation of spent coffee ground (SCG) was conducted using Lactobacillus plantrum. Fermentation was performed at moisture content of 70% and temperature of 39°C with anaerobic air tension for 48 h. Four adult rams (ini...
Introduction Application of enzymes to improve nutrients digestibility of plant-based feed ingredients for swine and poultry has now been studies for decades. Initially, the main focus was phytase to break down the phytate molecule and release the attached phosphorus molecules. In the last two decades, enzymes to assist digesting NSP were developed, tested, and commercialized. In the meantime, ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
This study was conducted to evaluate the effects of dietary supplementation of protected organic acid blends including medium chain fatty acids and different nutrient density diets on growth performance, nutrient digestibility and faecal noxious gas content in growing pigs. A total of 80 crossed [(Landrace × Yorkshire) × Duroc] growing pigs with an initial body weight (BW) of 22.61 ± 2.32 kg we...
Extended Abstract Introduction and Objective: Tannins have many limiting effects on consumption, nutrient digestion, growth and performance, palatability. There are many plants and by-products that are limited in animal feed due to the high content of anti-nutritional compounds such as tannins. The use of methods that can reduce the amount of these compounds will allow their use in animal feed...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
The objective of this study was to investigate the effect of enzymolytic products of soybean meal (ESBM), as one of the protein sources in the diet, on the growth performance, nutrient digestibility and immune function of weaned piglets. Soybean meal produced by bioprocessing with fermentation and enzymolysis contains reduced anti-nutritional factors and improved protein utilization. A total of...
