1. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

2. Composição nutricional e valores energéticos determinados com frangos de corte de coprodutos do processamento do etanol de milho
ABSTRACT It was determined by the total collection of excreta method, with broilers from 22 to 32 days of age, the coefficients of apparent metabolism of dry matter, crude protein and crude energy and apparent metabolizable energy corrected for zero nitrogen balance (AMEn) of the ethanol co-products of corn: acid oil and dried distillery grains with soluble

3. Influência da qualidade micotoxicológica e nutricional de híbridos de milho no custo da ração de frangos de corte
RESUMO Objetivou-se avaliar as variáveis micotoxicológicas e nutricionais de híbridos de milho com diferentes características que influenciam no custo da ração para frangos de corte. Foram avaliados 26 híbridos de milho geneticamente modificados nas safrinhas de 2016 e 2017, com diferentes germoplasmas, textura de endosperma e duração do ciclo. Nos

4. Blood parameters of Angus and Nellore young bulls fed diets with or without forage.
ABSTRACT We evaluated blood parameters of Angus and Nellore bulls fed diets with and without forage. Forty animals with initial body weight (BW) of 380±16.2 kg were housed in individual stalls. Eight bulls of each breed were fed a whole shelled corn (WSC) diet [850 g kg−1 of WCS and 150 g kg−1 of a pellet based on soybean meal, dry mater (DM) basis] or

5. METABOLIZABLE ENERGY OF RICE BRAN, COTTONSEED MEAL AND WHEAT BRAN FOR SLOW-GROWING BROILERS AT TWO AGES
Resumo O objetivo nesta pesquisa foi determinar a composição bromatológica e os valores de energia metabolizável para frangos de corte de crescimento lento em diferentes idades dos ingredientes: farelo de algodão, farelo de arroz e farelo de trigo. Para determinação dos valores energéticos foi utilizado o método de coleta total de excretas em dois e

6. Effect of Nitrogen Addition to Shielding Gas on Cooling Rates and in the Microstructure of Thin Sheets of Duplex Stainless Steel Welded by Pulsed Gas Tungsten Arc Welding Process
The effect of the nitrogen content in the shielding gas and its effect on temperature distributions at the welded zone of thin sheets of duplex stainless steel have been evaluated. The duplex stainless steels have many features due to unique microstructural combination of austenite and ferrite grains. The phase balance can be easily shifted depending on the

7. 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

8. Do live or inactive yeasts improve cattle ruminal environment?
ABSTRACT This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility of nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, and ruminal ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental perio

9. Productivity and crude protein concentration of Tifton 85 pasture-based mixed with pinto peanut
RESUMO Sistemas forrageiros constituídos pelo consórcio gramínea-leguminosa equilibram a oferta de forragem e minimizam impactos ambientais, pela redução da fertilização nitrogenada. O amendoim forrageiro tem várias características que são adequadas aos consórcios forrageiros, mas ainda não foram adequadamente explorados. O objetivo deste trabalh

11. Trophic dynamics (Dissolved Inorganic Nitrogen-DIN and Dissolved Inorganic Phosphorus-DIP) in tropical urban estuarine systems during periods of high and low river discharge rates
Abstract: This paper focused on the use of the biogeochemical LOICZ (Land Ocean Interactions in the Coastal Zone) to investigate the dynamics of DIN and DIP nutrients among three highly urbanized tropical estuaries (Barra das Jangadas (BJ), Recife (RE) and Timbó (TB)), located in the northeastern region of Brazil. The input data were obtained through in sit

12. Fibrous feedstuffs for the nitrogen retention of growing pigs
RESUMO: O objetivo deste estudo foi medir o balanço de nitrogênio (N) de suínos alimentados com dietas limitantes em lisina contendo níveis práticos de inclusão de farelo de trigo (FT) ou casca de soja (CS). Foram utilizados 24 suínos machos castrados com peso médio inicial de 57,36±2,01 kg e 72,68±3,24 kg nos experimentos 1 e 2, respectivamente.
