Daily rhythms of body core temperature and liver function were recorded in goats maintained under various schedules of lighting and feeding. Concentration of urea in the blood was used as an index of digestion-driven hepatic activity, whereas concentration of cholesterol served as an index of autonomous hepatic activity. Body temperature exhibited robust circadian rhythmicity in the presence an...

Food availability is a primary driver of avian population regulation. However, few studies have considered the effects of what is essentially a massive supplementary feeding experiment: the practice of wild bird feeding. Bird feeding has been posited as an important factor influencing the structure of bird communities, especially in urban areas, although experimental evidence to support this is...

The present study was designed to investigate the effect of molasses feeding on biochemical and hormonal parameters in Sahiwal and Karan Fries heifers under two feeding regimes, i.e. feeding regime-1, as per the NRC (2001) and feeding regime-2 having 15 % higher energy (supplementation of molasses) than NRC (2001). Twelve healthy heifers (18-24 month) of each Sahiwal and Karan Fries were select...

Biogas biodesulfurization by an anoxic biotrickling filter packed with open pore polyurethane foam at the laboratory scale (packed volume 2.4L) has been studied. The biotrickling system was operated for 620 days with biogas supplied continuously and two nitrate feeding regimes were tested (manual and programmed). Biomass immobilization was carried out under the manual nitrate feeding regime and...

The effect of light regime and feeding system on broiler performance, carcass traits, serum hormones and metabolic profiles was studied using eight hundred and ten one-day-old broiler chicks from Arbor Acres strain. Broilers were distributed randomly in 3 by 3 factorial arrangement. Three light regimes, (continuous light (23L: 1D), constant light (15L: 9D) and intermittent light (4L: 8D)) were ...

Total and specific activities of alaninaminotransferase (Al-AT) were determined in general tissues, mitochondrial and cytosol fractions of visual, orbital, motor, limbic areas of brain cortex and hypothalamus of three-month old and one-year old rats under 10-20 days and 30 days protein deprivation and under recovery of normal food regime during the same terms. It was found out that Al-AT activi...

The connection between a feeding regime with a high proportion of concentrates and laminitis is well recognized in domestic animal medicine but has received little attention in captive wild hoofstock. We used the occasion of a transport of two ruminant groups, that necessitated immobilization, for an evaluation of the appearance of the hooves on the one, and of the pH of the rumen fluid gained ...

We consider a Mode III lattice with an interface layer where the dynamic crack growth is caused by a localised sinusoidal wave. In the wave–fracture scenario, the ‘feeding wave’ (here also called the knife wave) delivers energy to the moving crack front, while the dissipative waves carry a part of this energy away from the front. The questions addressed here are: What are the conditions of exis...

In this study, the potential of four different culture selection methods under short-term enrichment time (STE) to accumulate PHA-producing bacteria in mixed activated sludge was compared and the most efficient culture selection method was introduced. This means, PHA-producing microbial community was firstly enriched in a sequencing batch bioreactor (SBR) with four different selection methods i...
