Detecting Enterotoxigenic Escherichia coli in animal production: method develop...
Barros, Maria Margarida; Campos, Ana Maria; Oliveira, Ricardo; Castro, Joana; Almeida, Gonçalo Nieto; Silva, Sónia; Monteiro, Divanildo OutorSwine enteric colibacillosis is a disease characterized by an intestinal infection caused by the colonization of enterotoxigenic Escherichia coli (ETEC). This infection mostly causes illness or death in neonatal and weaned pigs making it responsible for significant economic losses worldwide [1,2]. Bacterial fimbriae (F4/F5/F6/F18) allow the adhesion of the bacteria to epithelial cells, and when both the immunol...
Aptamers for blocking enterotoxigenic Escherichia coli
Barros, Maria Margarida; Oliveira, Ricardo; Campos, Ana Maria; Castro, Joana; Araújo, Daniela; Silva, Sónia; Monteiro, Divanildo Outor; Almeida, CarinaThe most common bacterial pathogen causing enteric infections in swine is enterotoxigenic Escherichiacoli (ETEC). ETEC-associated diseases, lead to acute diarrhoea and eventual death of the animal, resulting in significant costs to the swine industry [1]. The toxins/fimbriae produced areessentialfor theirpathogenicity. Fimbriae are responsible for the first adhesion of ETEC to the intestinal epithelial cells, g...
Relación entre los depósitos de grasa corporal e el espesor da grasa perirenal ...
Monteiro, Divanildo Outor; Mourão, J. L.; Pinheiro, Victor; Guedes, Cristina; Silva, SeverianoEste trabajo tuvo como objetivo estudiar la metodología de ultrasonidos en tiempo real (UTR) para estimar las reservas de grasa de conejas con diferente condición corporal a partir de medidas de espesor da grasa perirenal, teniendo el riñón como referencia. Se han efectuado mediciones de espesor de grasa perirenal in vivo, en 21 conejas adultas, por la técnica de UTR y a continuación se han cuantificado los dif...
Effects of the dietary incorporation of untreated and white-rot fungi (Ganoderm...
Ribeiro, Luís; Silva, Arnaldo Alves Dias da; Bennett, Richard N.; Monteiro, Divanildo Outor; Marques, Guilhermina; Mourão, J. L.; Rodrigues, MiguelThe aim of this study was to evaluate the effects of the level of inclusion of olive leaves and its pre-treatment with Ganoderma resinaceum Boud on growth performance, nutrient digestibilities and caecal fermentation. A total of 48 rabbits were kept in individual cages and divided in 4 groups of 12 animals. Animals were fed ad libitum with one of four diets based on a basal feed for growing rabbits – Control di...
Growth performance, carcass characteristics and meat quality of growing rabbits...
Pinheiro, Victor; Silva, Severiano; Monteiro, Divanildo Outor; Silva, José António; Mourão, J. L.The study was carried out to investigate the effects of two housing systems on the growth performance, carcass traits, and meat quality of growing rabbits during the terminal fattening period. The rabbits were lodged in conventional cages between 35 and 59 days of age (growing period). At this age, they were moved into two different housing systems until they were 87 days of age (fattening period). During the f...
El manejo alimentario de los conejos en destete. Efecto sobre los rendimientos ...
Fontes, Paulo; Steczova, L.; Monteiro, Divanildo Outor; Mourão, J. L.; Pinheiro, VictorEn este trabajo se estudiaron los efectos del tipo de pienso en el final de lactancia sobre los rendimientos de las conejas y de los gazapos. Se han utilizado 30 conejas en el día 22 de lactación, que se dividieron en 2 grupos de 15. En uno de estos grupos se ha suministrado alimento de conejas (Grupo C) y en otro pienso de gazapos (Grupo G). Este manejo se ha mantenido hasta el destete y después las madres ing...
Strategies for mitigation of nitrogen environmental impact from swine production
Monteiro, Divanildo Outor; Mourão, J. L.; Rodrigues, Miguel; Pinheiro, VictorThis work presents strategies that can be implemented in order to minimize the environmental impact of swine slurry on soil, water, and air. This reduction can be achieved through decrease in nitrogen excretion and ammonia emissions. The correct feed formulation according to animal requirements, the increase in diet digestibility and improvement in animal performance can reduce nitrogen excretion. The use of ad...
Age affects the laying performance and egg hatchability of red-legged partridge...
Barbosa, Ágata Cristina Fernandes; Monteiro, Divanildo Outor; Mourão, J. L.; Pinheiro, VictorRed-legged partridge breeders are frequently reared in captivity with the aim of producing fertile eggs and chicks. However, little is known regarding the role of breeder age on fertility and egg production performance. Therefore, we investigated the effects of breeder age on egg size and shape, flock reproductive performance, fertility, hatchability, and embryonic mortality. In experiment 1, the effects of bre...
Effect of olive leaves on lipid and liver biochemical parameters in New Zealand...
Arantes, Regina Maria Rodrigues; Colaço, Aura; Pires, Maria João; Monteiro, Divanildo Outor; Mourão, J. L.; Oliveira, Paula; Pinheiro, VictorIn this experimental work was studied the effect of Olive leaf addition to diets of New Zealand white X California rabbits (Oryctolagus cuniculus cuniculus) on lipid and liver biochemical parameters.
Utilização de técnicas de ultrasonografia em tempo real e de bioimpedância na d...
Morais, Raul; Monteiro, Divanildo Outor; Mourão, J. L.; Pinheiro, Victor; Guedes, Cristina; Silva, SeverianoForam utilizadas 20 coelhas das técnicas de ultrasonografia em tempo real e da bioimpedância A espessura da gordura escapular e após o abate foram determinad medida de gordura escapular está visceral a r = 0,85 para a perirenal; P também correlacionada (r = medidas de ultrasonografia e de resistência P < 0,01, respectivamente). Com a utilização da vivo, foi obtida por análise de 0,128PV; R 2 =0,865; P < 0,001 7...
