Effect of dietary supplementation of raw and extruded grass pea seeds (<i>Lathyrus sativus</i> L.) on activity of pancreatic enzymes in pigs

Abstract

The studies were carried on 24 pigs divided into 4 groups: control and 3 experimental. The pigs were fed for 8 weeks the diets: basic diet (control group) and supplemented with 10% raw grass pea seeds (group II) or with 10%) raw grass peas seeds plus methionine (group III) and supplemented with 20% extruded grass pea seeds and methionine (group IV).The protein content in the pancreas did not differ significanty between mean valeus for control and experimental groups. In the control group the protein content in pancreas amounted 755.00 ± 52.7 mg/ml, while in the three experimental groups 691.27 ± 25.55, 715.83 ± 54.84 and 763.33 ± 50.62 mg/ml, respectively. Proteolytic activity of the pancreatic homogenates was significantly lower in both experimental groups (II and III) of pigs fed on diets with 10% raw grass pea seeds. There were no significant differences between the pigs from group IV and control.Tryspin activity of pancreatic homogenates from pigs of the groups II and III was significantly lower than in control pigs and pigs from group IV.

“…Also, the initially low protein level of GPS compared with SBM Table (1), as well as the non sufficient processes (soaking, fermentation and germination) may consider as another impact on decreasing growth parameter particularly in the high ration of substitution. These results agree with [25] and [4]. On the other hand, soaking, fermentation and germination processes may due to some extent to inhibit the anti-nutritional substance.…”
