13. Effects of varying levels of dietary protein and net energy on growth performance, nitrogen balance and faecal characteristics of growing-finishing pigs
ABSTRACT This experiment was conducted to evaluate the effects of dietary protein and net energy (NE) levels on growth performance, nutrient digestibility, nitrogen metabolism, and faecal microbiota of growing-finishing pigs. Eighteen crossed barrows were randomly allocated into one of three dietary treatments: high protein + high NE diet, low protein + high

14. RESEARCHING NEW WAYS TO REDUCE N2O EMISSION FROM A GRANULAR SLUDGE SEQUENCING BATCH REACTOR TREATING DOMESTIC WASTEWATER UNDER SUBTROPICAL CLIMATE CONDITIONS
ABSTRACT N2O emissions from wastewater treatment plants have become an important issue, since this compound is a significant greenhouse gas that affects the sustainability of sewage treatment. This work aimed to investigate and to reduce N2O emission from a pilot-scale aerobic granular sludge sequencing batch reactor (AGS-SBR) operated for carbon and nitroge

15. A novel simplified scoring system for predicting mortality in emergency colorectal surgery: prediction model development
ABSTRACT BACKGROUND: Despite advances in surgical approaches, emergency colorectal surgery has high mortality and morbidity. OBJECTIVE: We aimed to create a simple and distinctive scoring system, for predicting mortality among patients undergoing emergency colorectal surgery. DESIGN AND SETTING: Prediction model development study based on retrospective

16. Effect of Withania somnifera on gentamicin induced renal lesions in rats
ABSTRACT Gentamicin induced renal complications are well known in humans and animals. Medicinal properties of Withania somnifera (L.) Dunal, Solanaceae, are recognized to improve renal functions. However, the pharmacological function of W. somnifera is not completely understood. We sought to unravel medicinal therapeutic function of W. somnifera on gentamici

17. NITROGENATED FERTILIZATION FAVORS VEGETATIVE RESCUE AND PROPAGATION OF Ilex paraguariensis
ABSTRACT The vegetative growth of plants depends on the nutritional conditions of the soil, mainly in relation to the N element. This element favours the formation of cytokines and auxins, essential hormones for sprouting and rooting, respectively. The objective of this study was to evaluate the influence of nitrogen fertilization of Ilex paraguariensis moth

18. Contents of macronutrients and growth of ‘BRS Marataoã’ cowpea fertigated with yellow water and cassava wastewater
Resumo O uso agrícola de águas amarelas associadas à manipueira é uma técnica sustentável, uma vez que possibilita a redução de custos com a aquisição de fertilizantes industrializados e minimiza a poluição ambiental ocasionada pela destinação final inadequada desses efluentes. Neste contexto, objetivou-se com este trabalho avaliar os teores de

19. Effect of observed individual data of performance and excretion on life cycle assessment of piglets
ABSTRACT: The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replica

20. Increased urinary losses in piglets fed diets containing high levels of glycerin
ABSTRACT This study evaluated the nutritional value of glycerin added to diets of weaned piglets and its effects on animal performance and urinary losses. Weaned piglets were individually housed in metabolic cages and fed diets in which a basal diet containing lactose (Gly0) was replaced by 50 (Gly50), 100 (Gly100), or 150 g kg−1 (Gly150) of glycerin; or a

21. Limnology of shallow lakes of the semi-arid Central Pampa of Argentina
Resumo Objetivo No Pampa Central da Argentina, há três regiões fitogeográficas criadas pela diminuição da precipitação vinda do oeste. Essa região possui um grande número de lagos sendo a maioria desses temporários com hidroperíodos definidos por ciclos climáticos, embora alterados pela ação antrópica. Alguns desses lagos foram estudados co

22. Agronomic performance and sweet corn quality as a function of inoculant doses (Azospirillum brasilense) and nitrogen fertilization management in summer harvest
ABSTRACT The inoculation of sweet corn seeds with Azospirillum brasilense in association to nitrogen fertilizer may be an agronomic alternative for increasing the crop yield and net income of plant growers. Therefore, the aim of this study was to investigate the effect of the different doses of inoculant (Azospirillum brasilense) associated to the nitrogen f

23. Predicting post-absorptive protein and amino acid metabolism
ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic per

24. Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland
ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativ
