The data used came from two trials undertaken under the same climatic conditions (spring-summer). In both trials pluriparious buffaloes were utilized similar in weight, body condition score, and milk production from the previous year. From the first trial the data used was from the sub-period 23-88 DIM provided by seven animals fed ad libitum with diet A (6.69 MJ/kg DM; 158.30 g/kg of crude pro...

The water footprint (WF) of a product refers to freshwater consumed during production (1). We calculated bioenergy WFs assuming crop water requirements are met (2); Jongschaap et al. (3) correctly point out that this is not always true, giving an example for jatropha grown under poor, rainfed conditions in South Africa. Yields are generally expressed in ton/ha, but, when water is scarcer than l...

Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

The carbon dioxide gasification performance of low-quality lignite-agroindustrial/forest waste blends was investigated in terms reactivity, conversion, cold gas efficiency, product composition and heating value. experiments were conducted a fixed bed unit thermal analysis mass spectrometer system. Raw materials, chars, liquids gases quantitatively analyzed their energy content determined. Syner...

The performance of a tunnel furnace and dryer in brick production was exergoenvironmentally assessed. real data factory Turkey with daily capacity 392 tons fired bricks were used the analysis. exergoenvironmental factor control volume calculated as 0.87. specific cost determined to be 559.55 €/h, 3.39 €cent/ kg 1.94 €cent/MJ. exergoeconomic environmental damage prevention obtained 0.41 € cent/M...

An energy system is described in which, in both single-stomached and ruminant animals, the heat increment of feeding is considered to be linearly related to five measurable quantities. For both kinds of animals three of the quantities, with their heat increments in parentheses, are urinary N (wu; kJ/g), faecal organic matter (wd; kJ/g) and positive protein retention (wp; kJ/g). In ruminants the...

The purpose of this study was to examine the effect of an 18-wk weight-training program on average daily metabolic rate (ADMR). Before the intervention and in weeks 8 and 18 (T0, T8, and T18, respectively) data on body composition, sleeping metabolic rate (SMR), food intake, energy cost of the weight-training program (EEex), and nontraining physical activity (accelerometer) were collected in th...

Glucose metabolism was studied in ewes fed 800 g chopped alfalfa hay (H) or 400 g alfalfa hay and 400 g corn grain given in whole (HWC), ground (HGC) or extruded (HEC) form. Daily intake of metabolisable energy and crude protein were: 5.8 MJ, 109 g; 9.0 MJ, 84 g; 9.5 MJ, 84 g and 8.5 MJ, 88 g in H, HWC, HGC and HEC, respectively. In situ ruminal degradability ranked whole, ground, and extruded ...
