Caecal microflora and fermentation pattern in exclusively milk-fed young rabbits.
Thirty-two SPF New Zealand White rabbits of both sexes were used in this experiment. They were sequentially slaughtered at 22, 29, 35 and 42 days of age. The rabbits were only milked by their mother and by foster mothers (no access to solid food) throughout the experiment. They exhibited a caecal fermentation pattern that turned towards a proteolytic metabolic activity (high levels in NH3 and i...
متن کاملIn vitro study of the age-dependent caecal fermentation pattern and methanogenesis in young rabbits.
The caecal fermentation pattern, including methanogenesis, was studied in young rabbits using in vitro batch incubations. Six conventional litters of eight rabbits each were used. At the age of 22, 25, 28, 32, 36, 42 and 56 days, an animal was slaughtered from each litter and its caecal contents were used for in vitro batch incubations at 39 degrees C/24 h. The incubated samples were analysed f...
متن کاملRelationships between microflora and caecal fermentation in rabbits before and after weaning.
Some microbiological and biochemical parameters of caecal content were studied in 15- to 49-d-old rabbits that were slaughtered sequentially. The ammonia level did not differ before weaning (11.5 mmol/L on average) (P = 0.41) or after weaning (7.4 mmol/L on average) (P = 0.19) but decreased by 40% (P < 0.001) between days 29 and 32. The level of pH decreased linearly (P < 0.001) throughout the ...
متن کاملInfluence of starch digestion in the large intestine of sheep on caecal fermentation, caecal microflora and faecal nitrogen excretion.
I . The concentrations of volatile fatty acids (VFA) in the rumen and caecum were compared when sheep were given barley or dried grass. The molar proportions of VFA in the caecum resembled those in the rumen except that the proportions of isobutyric and isovaleric acids were higher in caecal than in rumen fluid indicating an extensive breakdown of protein during fermentation in the caecum. 2. T...
متن کاملEffect of type of lucerne hay on caecal fermentation and nitrogen contribution through caecotrophy in rabbits.
Seventy-five New Zealand White x Californian rabbits were used to study the influence of the chemical composition of lucerne hay on caecal and caecotrophy characteristics. Five lucerne hays varying in chemical composition were ground and formed into pellets. These were the sole form of nutrition during the experiment. The type of lucerne hay did not affect caecal volatile fatty acid concentrati...
