Development of the rumen digestive functions in lambs placed in a sterile isolator a few days after birth.
The development of the rumen digestive functions was studied in lambs placed in sterile isolators at 1, 4, 8 or 9 days of age to define the role of the bacterial species that colonize the rumen just after birth. The values of the main rumen digestive parameters (pH, concentrations of volatile fatty acid, ammonia, lactic acid) in these lambs were close to those observed in conventional controls....
متن کاملUltrastructure of the myenteric ganglia in the rumen, reticulum, omasum and abomasum of grey, white and black Karakul lambs.
Homozygous grey and white Karakul lambs die after they have reached weaning age. This is due to a lethal gene causing digestive disturbances. Previous studies revealed that grey and white lambs have large, milk-filled rumens; the phenomenon was attributed to a significant decrease in the number of myenteric ganglia and neurons in the rumen wall. This study was undertaken to determine whether an...

Including these in the ration is fairly easy; however, some studies indi cate that injecting these into lambs upon receiv ing is more advantageous than day-to-day vitamin supplementation. Water soluble vita mins (B vita mins) usually are not needed unless lambs ar...
متن کاملA descriptive study of rumen digestion in meroxenic lambs according to the nature and complexity of the microflora.
We studied in meroxenic lambs, i.e. in lambs with a simplified digestive microflora, the effect of the microflora on the quantities of solid feed intake and on the main digestive parameters in the rumen. Axenic lambs were inoculated with a more or less complex flora, obtained by diluting (10(-8), 10(-7), 10(-8) a pool of rumen fluid taken either from young conventional lambs before weaning from...
متن کاملComparison of the Fatty Acid Composition of the Longissimus Dorsi Muscle of Kids, Lambs and Calves Produced under Iranian Transhumant Production System
Transhumant production system (TPS) is a type of extensive livestock production practiced by transhumant pastoralists in which indigenous livestock breeds are mainly fed a pasture-based diet. The hypothesis tested in this work was whether differences existed between fat samples from the different species in respect to ratios of n-6/n-3, and polyunsaturated fatty acids to saturated fatty acids. ...
