Five growth and ten digestibility trials were carried on growing male Bouscat rabbits to study the effect of some methods applied for improving the efficiency of residual small bowel segments after resection of its
5.
Forty rabbits were divided into five groups, each of eight animals. The first one was used for measuring the normal data concerning the digesti bility of the ration and its nutritive value together with the growth per formance. Rabbits of the second group were subjected to resection of about two-thirds from their small intestine. Some surgical operations
following the massive resection were applied on rabbits of the rest of the groups for increasing the efficiency of the residual small bowel seg ments. These operations were artificial valve, artificial valve with reverse segment and reverse segment alone.
The data obtained indicated that resection of about two-thirds of small bowel markedly depressed all the parameters studied which related to digestibility and nutritive value of the ration and also growth per formance, while the surgical safeguard operations followed it, markedly improved these parameters. The artificial valve is the most efficient methods for management the disorders resulted by massive resection of small intestine, followed by artificial valve with reverse segment and finally comes the reverse segment alone.
