“…In the pig, it has been shown that the level of fibre in the diet affects the volume of pancreatic juice secreted (LANGLOIS et al 1987) and the total output of protein and enzyme activity are mainly regulated by the intake of protein, carbohydrate and fat (BRANNON 1990). The present study is thus in agreement with these findings and also demonstrates the dietary effects on the bicarbonate-chloride exchange mechanism.…”

Introduction Cowpea (Vigna unguiculata) is a valuable protein source that can contribute towards overcoming a predicted protein deficit equivalent to more than 1 000 000 t oilcake in Southern Africa by the year 2000 (Nell et al. 1992). However, like most other legumes, cowpeas contain antinutritional factors (ANFs) (Makinde et al. 1996). It has also been shown that feeding raw cowpea causes reduced growth and histomorphometric changes in the various segments of the intestine (Makinde et al. 1997) attributable to ANFs. The major ANFs in the cowpea are trypsin inhibitors, tannins and phytates (Aletor and Aladetimi 1989). Although the protease inhibitors are found in most legumes, only soybean inhibitors have been thoroughly investigated (Liener and Kakade 1980), and trypsin inhibitors in other legumes have received little attention.

“…As far as the pancreatic secretion was concerned, the daily volume of juice secreted was in the range of values obtained by others (Partridge et al, 1982;Zebrowska et al, 1983;Corring et al, 1986;Langlois et al, 1987). The pancreatic juice flow rate was shown to be affected by the concentration of the diet (ie, liquid, solid, semisynthetic or natural), being lower with a semi-synthetic diet (Partridge et al, 1982;Zebrowska et al, 1983).…”

“…It was lower in animals fed a semisynthetic diet than in animals given a normal diet with similar amounts of nutrients (1.9 g vs 2.1 g according to Zebrowska et al, 1983; 1.1 g vs 1.5 g according to Partridge et al, 1982). The pancreatic endogenous total nitrogen production was 2.1 g per day in the pig fed heated soyabean (Corring et al, 1986) or 2.3 g per day when the diet contained wheat (Langlois et al, 1987). Furthermore, the present study shows that the amount of pancreatic nitrogen increased after meal intake, as reported earlier (Corring, 1980).…”

Summary -The aim of the present work was to study the endogenous contribution of the exocrine pancreatic and biliary secretions to the total endogenous nitrogen production in the pig. Three growing Large White pigs weighing 45 t 2.5 kg were fitted with permanent fistulae in the pancreatic duct, the bile duct and the duodenum. They were adapted to a semi-synthetic casein diet for 14 d before surgery. In a 7-d post-operative period and an 8-d experimental period, they were fed the same diet. Secretion rates were recorded, total nitrogen and TCA (trichloroacetic acid) insoluble nitrogen were determined in representative pancreatic juice and bile samples.Daily pancreatic juice and bile flow rates were very similar: 1 850 and 1 820 ml, respectively. The amount of endogenous total nitrogen secreted in the intestinal lumen was 3.6 g per day: 1.9 g N through pancreatic secretion and 1.7 g N through bile secretion. Pancreatic nitrogen increased after meal intake, whilst the kinetics of nitrogen production in the bile were

“…Similar results were obtained in this experiment and treatment three and five improved crude protein utilization compared with the control. It is possible that the inclusion of WB in diets might have enhanced the secretion of digestive enzyme and juices that are beneficial to protein digestion (Langlois et al, 1987;Valette et al, 1989). Research indicated that microbial phytase increased the dietary nitrogen retention (Ketaren et al, 1993;Mroz et al, 1994).…”

An experiment was conducted to determine effects of wheat bran (WB) phytase on production performance and nutrient utilization in laying hens. Three hundred and seventy-five Lohmann hens at 32 weeks of age were randomly allotted to treatments of fifteen hens per pen with five pens per treatment. Five experimental diets were formulated. Diet one (control) contained 0.19% inorganic phosphate (Pi) from dicalcium phosphate. On the basis of diet 1, diet 2 and 3 were formulated to contain WB 5% and 10%, respectively. In diet 4 and 5, the WB was fixed at the level of 10% with Pi level adjusted to 0.14% in diet 4 and completely replaced with 500 U/kg microbial phytase in diet 5. The results showed that treatment three improved egg yield (P = 0.142), feed conversion ratio (FCR) (P = 0.011), utilization of crude protein (CP) (P = 0.060) and total phosphorus (tP) (P < 0.001), and serum Pi concentration (P = 0.016) compared with the control. Ten percent of WB replacing 0.05% Pi did not influence either egg yield or nutrient utilization. Compared with the control, treatment five improved FCR (P = 0.011) and utilization of CP (P = 0.060) and tP (P < 0.001), but did not influence either performance or serum parameters. The current study suggests that wheat bran could be used successfully in laying hen diets and wheat bran and microbial phytase supplemented together could replace inorganic phosphate completely.
