Efeito da adubação nitrogenada ou de leguminosas no ganho de peso vivo de bovinos em pastagens de capim-colonião

Pesquisa Agropecuária Brasileira (1985)

Vanildo Favoretto Ricardo Andrade Reis Paulo de Figueiredo Vieira Euclides Braga Malheiros

O presente trabalho teve por objetivo avaliar o ganho de peso vivo de bovinos submetidos a tres tipos de pastagens de capim-coloniao ( Panicum maximum Jacq.): coloniao testemunha (sem adubacao nitrogenada); coloniao adubado com 100 kg/ha de nitrogenio; e coloniao consociado com soja perene ( Neonotonia wightii Verde.) e centrosema ( Centrosema pubescens Benth.). Foram usados novilhos da raca Guzera, com idade variavel de 12 a 15 meses e peso vivo medio de 210 kg. O sistema de pastejo foi rotativo, sendo o ajuste pasto-animal realizado pelo metodo de carga variavel. As pesagens dos animais e amostragens do material vegetativo foram realizadas a cada 35 dias. Os resultados revelaram que, durante a epoca seca, os ganhos diarios e por hectare referentes ao tratamento consociado (0,264 kg/animal/dia e 85,73 kg/ha, respectivamente) foram superiores aos das pastagens adubadas com nitrogenio (0,114 kg/animal/dia e 19,93 kg/ha) e testemunha (0,140 kg/animal/dia e 36,60 kg/ha ). Ao final de quinze meses, as pastagens adubadas com nitrogenio e consociadas nao apresentaram diferencas nos ganhos de peso vivo por hectare, sendo estes, entretanto, 16% superiores em relacao ao da pastagem testemunha.

ABSTRACT The purpose of this research was analyze the fit of Gompertz function with or without fixing some of the parameters to describe body growth and major bodily chemical constituents of growing pullets. Weekly, data of body weight and chemical components of body free of feathers and feathers were collected from 1,200 chicks of four laying strains (Hisex Brown, Hisex White, Hy Line Brown and Hy Line White W36) until 18 weeks of age. The variables were subjected to two adjustments fixing, or not, some parameters of Gompertz function. The allometric model parameters were calculated for the chemical components. The lipid and protein composition of the body free of feathers were the components with the biggest change in the last weeks. Moreover, the chemical composition of the feather showed small variation. The parameters of the Gompertz function assumed values according to the employed adjustment, especially for protein and fat of the body free of feathers carcass. The adjustment of the Gompertz function by fixing the two parameters allowed coherence and biological significance. The allometric coefficients indicate that as the protein weight increased, the proportion of fat increased and the proportion of water and ashes in the body decreased. The fit of the model allows setting the parameters with consistency and biological significance without losing accuracy in the estimates.

<b>High levels of dietary vitamin E improve the reproductive performance of female <i>Oreochromis niloticus</i></b> - doi: 10.4025/actascibiolsci.v36i1.19830

Acta Scientiarum Biological Sciences (2014)

Thálita Stefann Ribeiro Nascimento Marta Verardino De Stéfani Euclides Braga Malheiros Teresa Cristina Ribeiro Dias Koberstein

This study aimed to evaluate the effect of vitamin E on reproductive responses of female tilapia (Oreochromis niloticus). To this, isonitrogenous and isocaloric diets with different levels of vitamin E supplementation (200, 300, 400, and 500 mg kg-1) were provided to groups of females for 90 days. Supplementation positively influenced the volume of eggs produced, spawning rate, fecundity, hatching rate, average production of larvae, reproductive frequency and survival. The fertilization rate, weight, and diameter of the eggs were not affected by supplementation. This study showed that 400 mg kg-1 vitamin E in the diet during the reproductive period of female Nile tilapia are sufficient to ensure the best reproductive performance, providing efficient production of a larger number of larvae in the individuals of this species.

Canopy characteristics and tillering dynamics of Marandu palisade grass pastures in the rainy–dry transition season

Grass and Forage Science (2016)

Silvano Santana Liziane de Figueiredo Brito Mariana Vieira Azenha Aline Aparecida Oliveira Euclides Braga Malheiros

Abstract The objective of this study was to evaluate the effect of pasture management during the rainy–dry transition season in Jaboticabal, Brazil, on the structural and tillering characteristics of Marandu palisade grass. The treatments were as follows: 15 cm sward height in the rainy season and ungrazed in the rainy–dry transition season (15/0); 25 cm sward height during the rainy season and fixed stocking rate of 2·5 AU ha −1 during the rainy–dry transition season (25/2·5); and 35 cm sward height in the rainy season and fixed stocking rate of 2·5 AU ha −1 in the rainy–dry transition season (35/2·5). There were more herbage mass, stem and dead herbage mass in treatments 25/2·5 and 35/2·5 than 15/0. Tiller appearance rate was greater in treatment 15/0 and tiller mortality rate was higher in treatment 35/2·5 compared to treatment 15/0. Tiller population stability index was 1 in treatment 15/0 and lower in treatment 35/2·5. Although treatment 15/0 showed favourable structural and tillering characteristics, it also has the lowest herbage mass. Treatment 25/2·5 can be regarded as an adequate management strategy for Marandu palisade grass, since it has similar herbage mass and better tillering characteristics than treatment 35/2·5.

Experimental peritonitis in horses. Hematological and biochemistry aspects

Brazilian Journal of Veterinary Research and Animal Science (2000)

Luiz Cláudio Nogueira Mendes Luiz Carlos Marques R. P. Schocken-Iturrino Fernando Antônio de Ávila Euclides Braga Malheiros

Sixteen adult horses were randomly divided into 4 equal groups (GI, GII, GIII and GIV) of 4 animals and each group was injected intraperitoneally with one of the following suspension: Group I, 100 x 10(7) colony-forming units (CFU) of E. coli diluted in 500 ml of 0.9% saline; Group II, 100 x 10(7) CFU of Bacteroides fragilis in 500 ml of 0.9% saline; Group III, 100 x 10(7) CFU of E. coli in combination with 100 x 10(7) CFU of B. fragilis in 500 ml of 0.9% saline; Group IV, 500 ml of 0.9% saline. Leukopenia appeared in all animals inoculated with bacteria within the first six hours of the experiment. After this period, leukocytosis was observed in some inoculated horses. Horses inoculated with pure cultures of either E. coli or B. fragilis demonstrated mild and self-limiting peritonitis, whereas those inoculated with a combination of both bacteria demonstrated laboratory findings of higher intensity and duration.

Níveis de zinco na dieta de leitões recém-desmamados:Desempenho, incidência de diarréia, isolaento de E. coli e análise econômica

Boletim de Indústria Animal (2005)

Vânia Maria Arantes Maria Cristina Thomaz Rodolfo Nascimento Kronka Euclides Braga Malheiros Vinicius Mundim e Barros

The present experiment was conducted to determine the effect of the addition of different levels of zinc (0, 1500, 3000 and 4500 ppm) in the diet of weaned pigs on performance, diarrhea incidence and importance, E. coli, enterohemorrhagic E. coli and P. mirabilis isolation and economical analysis. Sixty crossed weaned piglets with 21 days of age, were used, arranged in a randomized design, with 4 treatment, 5 replications. The periods (P) considered were: P1, of the it weans (day zero) up to 14 days it after weaning; P2, from 15 to 42 days after weaning and Total (TP), of the day zero to the 42 days after weaning, for performance and economical analysis; week 1, week 2, and P1, for incidence and gravity of the diarrhea; collection of feces to the 0, 7 and 14 days after weaning for the microbiological isolation. The polinomial regression was used for the levels of Zn in the variables daily feed intake (DFI), daily weight gain (DWG) and feed:gain ratio (FG). The addition of 1500 ppm of Zn in diet was enough to improve piglets DWG and FG. ZnO was not effective in controlling E. coli and enterohemorrhagic E. Coli in the 14 days after weaning.

Positioning and number of nutritional levels in dose-response trials to estimate the optimal-level and the adjustment of the models

Ciência Rural (2014)

Fernando A. Souza Euclides Braga Malheiros Paulo Roberto Oliveira Carneiro

The aim of this research was to evaluate the influence of the number and position of nutrient levels used in dose-response trials in the estimation of the optimal-level (OL) and the goodness of fit on the models: quadratic polynomial (QP), exponential (EXP), linear response plateau (LRP) and quadratic response plateau (QRP). It was used data from dose-response trials realized in FCAV-Unesp Jaboticabal considering the homogeneity of variances and normal distribution. The fit of the models were evaluated considered the following statistics: adjusted coefficient of determination (R²adj), coefficient of variation (CV) and the sum of the squares of deviations (SSD).It was verified in QP and EXP models that small changes on the placement and distribution of the levels caused great changes in the estimation of the OL. The LRP model was deeply influenced by the absence or presence of the level between the response and stabilization phases (change in the straight to plateau). The QRP needed more levels on the response phase and the last level on stabilization phase to estimate correctly the plateau. It was concluded that the OL and the adjust of the models are dependent on the positioning and the number of the levels and the specific characteristics of each model, but levels defined near to the true requirement and not so spaced are better to estimate the OL.

Estudo da variação na estrutura da vegetação de duas cultivares de Panicum maximum jacq. (colonião e tobiatã) submetidas a diferentes tipos de manejo. 1. produção e densidade de perfilhos e de matéria seca

Pesquisa Agropecuária Brasileira (1992)

Ciniro Costa Vanildo Favoretto Euclides Braga Malheiros

O trabalho foi conduzido na FCAV-UNESP, Câmpus de Jaboticabal, com o objetivo de estudar os efeitos da presenca ou ausencia de adubacao nitrogenada (0 e 50 kg de N/ha/corte), de tres crescimentos sucessivos (21.12.87, 25.01.88 e 29.02.88) e de tres idades de corte (28, 35 e 42 dias), sobre a producao de materia seca e densidade de perfilhos de duas cultivares de Panicum maximum Jacq. (Coloniao e Tobiata), cortando-se a vegetacao em cinco estratos verticais (0-20; 20-40; 40-60; 60-80 e acima de 80 cm, em relacao ao nivel do solo). As amostras referentes aos diversos estratos foram separados em: folhas verdes, colmos verdes e material seco. Os resultados revelaram que apesar de a cultivar Tobiata ter apresentado maiores producoes de materia seca total e de folhas verdes, a cultivar Coloniao apresentou disposicao mais concentrada dessa producao, revelando maiores densidades de materia seca total e de folhas verdes. A adubacao nitrogenada (50 kg de N/La/corte) promoveu aumento na densidade de materia seca de folhas verdes de ambas as cultivares, sem, contudo, alterar a densidade de perfilhos, evidenciando o efeito do fertilizante no alongamento dos colmos, o que proporcionou melhor distribuicao de folhas verdes nos estratos superiores da vegetacao.
