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...

Effect of substitution of wheat starch by potato starch on the performance, dig...

The goal of this research was to study the effect of the substitution of wheat starch by potato starch (PS) on the performance, health and digestion of growing rabbits. Three experimental diets were formulated with 0%, 7% and 14% PS (PS0, PS7 and PS14, respectively) and similar starch contents (22% dry matter basis), proteins and fibre. The three diets were administered to three groups of 48 rabbits from weanin...

Real-time ultrasound to predict rabbit carcass composition and volume of longis...

Real-time ultrasonography (RTU) was used to measure the longissimus dorsi muscle (LM) volume in vivo and to predict the carcass composition of rabbits. For this, 63 New Zealand White × Californian rabbits with 2093±63 g live weight were used. Animals were scanned between the 6th and 7th lumbar vertebrae using an RTU equipment with a 7.5 MHz probe. Measurements of LM volume were obtianed both in vivo and on carc...

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...

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...
