T HREE switchback metabolism studies were conducted to study the effects of replacing corn with 5, 10 and 15% cane molasses. Five percent molasses had no significant effect on any of the parameters studied. At 10 and 15% molasses added at the expense of corn in the basal ration, nitrogen retention and apparent digestibility of dry matter and energy were all significantly improved (P< .05) . The...

The digestion method using a small proportion of a strong oxidizing agent perchloric acid seems to have been taken from a ’continuous flow method’, which was not designed for discrete digestion and analysis. There is considerable evidence that satisfactory digestion ofeven tMrly refractory substances can be achieved without the use of perchloric acid (1) and it is now usually recommended that p...

Story in Brief Corn steep liquor (CSL) and fermented ammoniated condensed whey (FACW) were compared to cottonseed meal (CS1\I) as protein sources f())' wintering 6 I lactating first-calf Hereford heifers and 32 yearling HerefOl'd heifers on nati\'e range. Cattle were allotted by weight and individually fed 6 days per week fill' 12 weeks one of four protein treatments: negative control (I\C). po...

soil unsaturated zone is one of the important parts of hydrological cycle that has an especial role in agricultural water resources management. the objective of this research was to determine the amount of root water uptake under simultaneous water, salinity, and nitrogen stresses as prevailing conditions in arid and semi-arid regions. to do so, the experiment was conducted with four quantitati...

Measurement of the distribution of the photosynthesis product in the symbiotic association of a legume, a mycorrhizal fungus, and nitrogen-fixing bacteria showed that the fungus incorporated 1 percent of the photosynthesis product and respired 3 percent. The nodules of a 5-week-old plant utilized 7 to 12 percent of the photosynthesis product. The legume compensated in partfor the needs of its m...

This paper presents results on nutrient concentrations estimations in the Upper Tombigbee watershed (northern Mississippi-Alabama region, USA). It details the hydrological model development and its use for providing stream flow, runoff, and nutrient concentrations (total phosphorus, TP, and total nitrogen, TN) for subsequent biological studies. Geographical locations of data collection on fish ...

in order to evaluate the efficiency of inoculation of chickpea seeds with mesorhizobium and application of nitrogen on yield and yield components of chickpea an experiment was conducted in research station of neishobour, khorasan-razavi. the experiment was conducted in randomized complete block design (rcbd) with four replications and 13 treatments including mesorhizobium (swri 1, 2, 3, 6, 9, 1...

Nitrogen is one of the major elements available to plants through biological nitrogen fixation, which has received much attention in recent years. The present study aims at improving tree legumes viz., Albizzia lebbeck, Pithecolobium dulce, Sesbania grandiflora, Albizzia amara, Enterolobium saman, Erythrina indica, Leucaena leucocephala, Acacia mellifera, Pongamia glabra and Acacia auriculiform...

High levels of turbidity and suspended solids are the major disadvantages of aerated lagoons. Aerated lagoon effluent filtration was investigated by Horizontal Roughing Filter (HRF). Removal efficiencies were determined by examining total phosphorus (TP) and total Kjeldahl Nitrogen (TKN) from HRF influent and effluent, simultaneously. HRF pilot system located on effluent pump station of Qom was...
