The experiment was carried out to evaluate the effect of wheat straw and urea additives on chemical composition, quality characteristics and ruminal degradability parameters of dry matter, neutral detergent insoluble fiber and crude protein orange pulp silage, in a completely randomized design, using nylon bag technique in the form of fore treatments (citrus pulp 1. without additive, 2. with 40...
the prevalent method of irrigation in paddy fields in iran is continuous ponding, which changes to intermittent method at the time of water shortage. soil cracks are the main problem in intermittent irrigation. in this study, effects of adding rice straw on some soil physical characteristics and cracks were studied in paddy soils of the guilan province of iran. the experiment was performed as s...
1. Possible association between high rates of feather pecking and increased stress were investigated in laying hens. 2. From week 19 to week 30 after hatching, 16 groups of 11 hens (white Lohman Selected Leghorn hybrids) were kept in pens with or without long-cut straw as foraging material and provided with food in the form of pellets or mash. 3. Stress was assessed by egg production, weight ga...
The objective of this study was to evaluate the effect of partially replacing forage sources (alfalfa hay) with treated wheat straw on nutrient digestibility, chewing activity, blood metabolites, rumen fermentation, and performance of finishing lambs. Wheat straw (WS) was treated with 7 % sodium hydroxide, 3.5 % salt, and 3.3 % calcium carbonate and then ensiled for 2 months. Twenty-three male ...
This research was conducted in order to determine chemical composition, gas production parameters, in vitro digestibility and ruminal degradability of Acroptilon repens at different phonological stages (vegetative, flowering and seeding) and its comparison with alfalfa hay and wheat straw in Completely Randomized Design. For this purpose, Acroptilon repens was prepared in three stages of growth...
Extended Abstract Introduction and Objective: Processing of agricultural by-products for animal feed can upgrade the supply of animal feed without increasing the current production and only by improving productivity via enhancing energy efficiency and maintaining it in the food supply chain, and at the same time, diminish the concerns of waste management, food security, resource constraints, a...
Thinning of the site to a target basal area of 65 ft/ac was conducted in June 1999 to maintain stands within the 50to 80-ft/ac basal area range recommended for red-cockaded woodpecker (Picoides borealis) habitat (US Fish and Wildlife Service [USFWS] 2009). Additionally, it was thought that by reducing stand stocking the remaining trees would have sufficient growing space to better respond to ma...
The main objective of this study was production of ethanol from three lignocellulosic biomasses like sugarcane bagasse, rice straw and wheat straw by Sacchromyces cervisae. All the three substrates were ground to powder form (2 mm) and pretreated with 3%H2O2 + 2% NaOH followed by steaming at 130 °C for 60 min. These substrates were hydrolyzed by commercial cellulase enzyme. The whole fermentati...
The study was carried out to explore the effects of replacing wheat straw with fungal treated wheat straw as an ingredient of total mixed ration (TMR) on the growth performance and nutrient digestibility in Nili Ravi buffalo male calves. Fungal treated wheat straw was prepared using Arachniotus sp. Four TMRs were formulated where wheat straw was replaced with 0 (TMR1), 33 (TMR2), 67 (TMR3), and...
Clostridium cellulolyticum is capable of producing glycosyl hydrolase enzymes as well as fermentation products including ethanol and acetate. In this study, the potential of using C. cellulolyticum for ethanol and volatile fatty acid production from straw and grape pomace was examined. For rice straw, the effects of alkaline pretreatment and substrate sterilization prior to fermentation on prod...
