Effect of mannan oligosaccharides on the performance, intestinal morphology and...

A common problem in rabbits is the occurrence of digestive disorders just after weaning. This problem is associated with instability of the cecal microflora and characterized by diarrhea, loss of appetite and increased mortality. In the current study the effects of mannan oligosaccharide (MOS, Bio-Mos®, Alltech Inc., USA), a natural growth promoter, were compared to a commonly used antibiotic growth promoter (A...

Use of ß-glucanases and ß-1,4-xylanases to supplement diets containing alfalfa ...

It is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and β-1,4-xylanases ...

Efecto de las restriciones alimentarias sobre el crecimiento de conejos de los ...

Neste estudo foram utilizados 166 coelhos com o objetivo de avaliar o efeito da restrição alimentar na taxa de crescimento. Os coelhos foram divididos em quatro tratamentos de acordo com o tempo de acesso ao alimento (ad libitum (C), acesso ao alimento durante 5 ou 10 horas por dia (D5 e D10, respetivamente) ou em dias alternados (D24)). Foram pesados semanalmente entre os 35 e os 70 dias de idade e o crescimen...

Relación entre los depósitos de grasa corporal e el espesor da grasa perirenal ...

Este 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...

1.Detection, Accumulation, Distribution, and Depletion of Furaltadone and Nifur...

Nitrofurans were broadly used as an extremely effective veterinary antibiotic especially in pig and poultry production farms. Because of fears of the carcinogenic effects on humans, the nitrofurans were banned from use in livestock production in many countries, including the European Union. The present study examines the accumulation, distribution, and depletion of furaltadone and nifursol and of their tissue-b...

Laboratory limits on dermatophyte diagnosis in rabbits with clinical lesions

ermatophyte infection or ringworm is a superficial cutaneous infection with one or more of the fungal species of the keratinophilic genera Microsporum, Trichophyton, or Epidermophyton and is a zoonosis with a great impact on public health. Dermatophytes were identified from rabbit sample cultures submitted to mycological examination in the Laboratory of Microbiology of the University of Trás-os-Montes e Alto Do...

El manejo alimentario de los conejos en destete. Efecto sobre los rendimientos ...

En 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...

Predicción de la composición de la canal de conejo con análisis de imágenes de ...

Este trabajo tuvo como objetivo estudiar una metodología de análisis de imágenes de músculo y grasa para estimar la composición de la canal de conejos en crecimiento. En 18 canales de conejos sacrificados a las 10 semanas de edad, las imágenes se obtuvieron en el plano de corte entre la 6 ª y 7 ª vértebra lumbar. Mediante el análisis de imágenes se obtuvieron mediciones de la superficie, perímetro, eje principa...

The effect of replacing inorganic trace minerals with selenium yeast and organi...

The aim of the study was to compare the performance profiles of broilers fed with a commercial inorganic mineral premix (control) with the ones obtained using an organic treatment (OTM). OTM included; selenium yeast and organic mineral chelates of copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe). Four identical houses with a total of 119.500 mixed-sex broiler chickens were used (2 treatments × 2 replicates)...
