Effect of milk composition and a dietary crude protein source on an increasing of resistance of growing-fattening rabbits to digestive disorders
PŘÍDOVÁ, Lenka
Recent findings showed that white lupine is a suitable alternative source of crude protein for feed mixtures of broiler rabbits. It was found that white lupine can completely replace the hitherto commonly used soybean meal , which in higher concentrations assigns a negative impact on the health of the gastrointestinal tract. For fattening rabbits are therefore all white lupine seeds suitable source of nitrogen compounds . White lupine seeds are also an important source of fat with a favorable profile and fatty acid composition . In further experiments it was found that the addition of white lupine into lactation diet rabbits significantly increased daily milk production and milk fat , which significantly reduces the amount of saturates and significantly increases the percentages of oleic acid , linolenic acid and eicosapentaenoic acid (EPA). Such milk nutrition rabbits, along with the use fattening mixtures from 17 days of age also contains white lupine , significantly reduce the health risk index rabbits in the first weeks after weaning. It is however clear whether the favorable health condition of weaned rabbits was due to higher acid content of EPA in milk, which are attributed to the organism significant physiological and immune function, or has a better state of health due to the fact that the rabbits received fattening diet containing white lupine , compared with rabbits receiving the diet with soy extracted scrap. Compared to soy white lupine also has a higher content of oligosaccharides rafinosové series , which is attributed to the prebiotic effect . The addition of white lupine in fattening mixtures may favorably affect the fermentation microflora activity appendicitis rabbits , thereby increasing the resistance of weaned rabbits digestive disorders . From the foregoing it is clear that there are many unclear issues that need to explain the experimentally .
