“…It has also been shown in the dog (Behrman and Kare, 1969), chicken (Wills and Hinners, 1968) and pig (Corring, 1975) (fig. 5) (Mourot and Corring, 1979) Rodgers (1970) and Mc Manus and Isselbacher (1970), the process of intestinal reesterification responds to changes in the amounts of lipid substrate digested. This is evident in fed animals which showed increased total specific monoglyceride acyltransferase activity as compared to the fasted ones (Rodgers, 1970 (Snook, 1965).…”

“…D'autre part, l'adaptation de la lipase à la teneur en lipides du régime est un aspect bien connu chez le porcelet (Mourot et Corring, 1979), en revanche son adaptation à la nature des lipides n'est pas évi-dente. Ainsi, le remplacement de l'huile d'olive par une graisse saturée n'a pas stimulé l'activité totale et spécifique de …”

Résumé — Au total, 24 porcelets de la race Alentejana (six animaux par traitement) sevrés à 21 jours ont été utilisé pour l'étude de l'adaptation digestive et métabolique des animaux à l'utilisation du son weeks of age were randomly affected to four treatments including two levels of wheat bran (0 or 15°/) and two sources of fat (5°/ of olive oil or 5% of beef tallow) in a 2 x 2 factorial arrangement. The effects of the level of wheat bran and fat source (olive oil or beef tallow) were evaluated on growth performance, faecal apparent digestibility (FAD) and activity of pancreatic and intestinal digestive enzymes. In addition, the effect of the diet on the serum level of glucose, urea, cholesterol and triglycerides was measured prior and during 5 h after an experimental meal. The inclusion of wheat bran to the diet decreased the FAD of energy by 3 and 6 percentage units in the presence of olive oil and tallow, respectively. A further reduction in the FAD of ether extract was observed when animals were fed wheat bran 65.4 versus 56.9°/, respectively. There is a significant (P < 0.01) interaction between fibre level and fat source on the FAD of NDF and hemicellulose, so the addition of wheat bran increased the FAD of these fractions only in the presence of olive oil. Compared to the diet containing beef tallow, FAD of dry matter and energy were increased by 2 and 4.5 percentage units by the addition of olive oil in the diet. Moreover, the FAD of ether extract was significantly higher (P < 0.01) for the diets containing olive oil (70%) than for those supplemented with tallow (52%). Despite an increase in the weight of the pancreas in piglets fed diets supplemented with wheat bran, total or specific activity of pancreatic enzymes were not significantly affected by the composition of the diet. The level of total cholesterol, HDL cholesterol and LDL cholesterol and that of triglycerides were not affected by the addition of tallow and consequently by the increase in dietary cholesterol.

“…Ingestion of the diet containing 21 % lard led to a particularly low trypsin activity. Such an effect was not observed either with 21 % sunflower oil or with diets including similar levels of peanut oil administered to growing pigs (Mourot and Corring, 1979 ;Simoes Nunes, 1982). It seems that lard exerts a depressive effect on the activity of trypsin.…”

“…Pancreatic lipase was long considered as a non-adaptative enzyme (Bucko and Kopec, 1968) but, owing to improved determination techniques, it was demonstrated that lipase did adapt to the amount of .lipids ingested in a large number of experiments and in many animal species (Behrman and Kare, 1969 ;Hulan and Bird, 1972 ;Mourot and Corring, 1979 ;Simoes Nunes et al, 1985 Nunes and Corring, 1979). The total lipid content of the pancreas was measured according to Folch et al (1957).…”
