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...

Sheep whole body composition predicted by in vivo real time ultrasound measurem...

Accurate measurement of changes in body composition and in the energy content of live animals is crucial to understand the responses to the intake of nutrients. Despite the accuracy of the serial slaughter technique in determining body composition, it is very expensive and comparisons within an animal became impossible thus the need for an accurate method to predict body composition in the live animal is obviou...

Utilização de técnicas de ultrasonografia em tempo real e de bioimpedância na d...

Foram 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...

Utilización de ultrasonidos en la monitorización de las re-servas corporales de...

Se han utilizado 20 conejas Nueva Zelanda×California (4,3±0,6 kg) para evaluar la capacidad de la técnica de los ultrasonidos en tiempo real (UTR) para predecir la grasa corporal. Se obtuvo in vivo la medida del espesor de la grasa escapular (EGEsc) por UTR y en las canales se ha cuantificado por desecación los principales depósitos de grasa. Se verificó que la medida EGEsc está correlacionada con los principal...

Estimation of rabbit hind leg muscle weight and muscularity by real time ultras...

Forty-four New Zealand White x Californian rabbits were used to evaluate the real time ultrasonography (RTU) in assessing hind leg muscle weight and hind leg muscularity. For in vivo muscularity determination animals were scanned over the hind leg using a RTU machine equipped with a 5 MHz probe. The RTU images were taken on hind leg at three positions perpendicular to femur bone. At each position a section of h...

In vivo rabbit carcass composition and longissimus dorsi muscle vol-ume predict...

The real-time ultrasonography (RTU) was used to measure in vivo the Longissimus dorsi muscle (LM) volume and to predict carcass composition of 63 New Zealand White X Californian rabbits. Animals were scanned between 6 th and 7 th lumbar vertebrae with RTU equipment with a 7.5 MHz probe, then weighed and slaughtered. Chilled carcass and reference carcass weight (RCW) were recorded and carcass dissected into me...

Prediction of apparent digestibility of hays from natural pastures of the North...

In the Northeast region of Portugal hays from natural pastures are traditionally used as the main feed during the period of drought and the evaluation of its nutritive value is essential. The aim of this study was to predict the apparent organic matter digestibility (OMD) of 21 hays from natural pastures based on chemical composition, pepsin-cellulase solubility of organic matter (OMS) and in vitro organic matt...
