“…In the present study, the form of pea seeds (raw or extruded) had a negligible effect on the morphology of the ileum and distal colon. Similar results were observed previously [53] and indicated that pea seeds (raw or extruded) had no effect on the epithelium of chickens’ intestine.…”

“…The high tannin content (7.26–12.11 g/kg) in peas may decrease the digestibility of protein and metabolizable energy in rats and chickens [52]. In the present study, thermal process did not change their content but it is suggested that modern cultivars of peas, such as Milwa with a low tannin content (0.96–1.10 g/kg), can be accepted in feeds for broilers [53]. …”

Effect of Replacing Soybean Meal by Raw or Extruded Pea Seeds on Growth Performance and Selected Physiological Parameters of the Ileum and Distal Colon of Pigs

et al. 2017

The use of pea seeds is limited due to the content of antinutritional factors that may affect gut physiology. Heat treatment such as extrusion may reduce heat-labile antinutritional factors and improve the nutritional value of pea seeds. This study determined the effect of partial replacement of soybean meal in pig diets by raw or extruded pea seeds on growth performance, nitrogen balance and physiology of the ileum and distal colon. The experiment was carried out in 18 castrated male piglets of initial body weight of 11 kg, divided into three groups. The animals were fed cereal-based diets with soybean meal (C), which was partly replaced by raw (PR) or extruded pea (PE) seeds. Nitrogen balance was measured at about 15 kg body weight. After 26 days of feeding, tissue samples were taken from the ileum and distal colon for histological measurements, and colonic digesta samples for analyses of microbial activity indices. The animals fed the PE diet had a significantly greater average daily gain than those fed the C diet and better apparent protein digestibility than those on the PR diet. Pigs fed the PR diet had a significantly greater butyric acid concentration and lower pH in the colon than pigs fed PE and C diets. There was no significant effect of the diet on other indices of microbial activity or morphological parameters. In conclusion, feeding a diet with extruded pea seeds improved growth performance of pigs, did not affect intestinal morphology and had a negligible effect on microbial activity in the distal colon.

“…The major antinutritional factors in peas are tannins and trypsin inhibitors (Smulikowska et al, 2001;Konieczka et al, 2014). Several researchers report that tannins can negatively influence nutrient digestibility by their ability to form complexes with proteins (Griffiths and Moseley, 1980;Gdala et al, 1992).…”

“…Several researchers report that tannins can negatively influence nutrient digestibility by their ability to form complexes with proteins (Griffiths and Moseley, 1980;Gdala et al, 1992). The other commonly recognized antinutritional substances occurring in pea seeds include trypsin and chymotrypsin inhibitors (Konieczka et al, 2014), which significantly reduce the activity of enzymes responsible for protein digestion and, as a consequence, result in deterioration of production results (Gatel and Grosjean, 1990). Two subspecies of pea are cultivated in Poland: P. sativum hortense, which is white-flowered, and P. sativum arvense, which has coloured flowers (pink, red, or purple).…”

Factors affecting the nutritional value of pea (<i>Pisum sativum</i>) for broilers

“…Research on the utilisation of peas in diets for young growing monogastrics reveals; however, research on the extent to which peas can replace SBM in these diets is limited [ 2 ]. It has been shown that partial substitution of dietary SBM with a high amount of raw peas (200–500 g/kg) may have a negative impact on broiler chicken performance [ 7 , 8 , 9 ]. This is primarily because of the action of secondary metabolites occurring naturally in the whole seeds (collectively referred to as anti-nutritional factors, ANF) or, as concluded by Nalle et al [ 10 ], due to the lack of careful consideration given to the protein and AA digestibility differences in feed formulations.…”

This study aimed to determine and compare standardised ileal digestibility (SID) coefficients of amino acids (AA) in raw seeds of the white-(WF) and the coloured-flowered (CF) field pea cultivar as sole sources of AA in the diets fed to broiler chickens aged 14 or 28 days. An additional purpose was to check the influence of exogenous protease added to pea-based assay diets on AA SID in birds at both ages. Each assay diet was offered to six replicate pens. On both sampling days, the contents from the lower half of the ileum were collected for determination of the apparent digestibility values. The SID coefficients were calculated using ileal endogenous AA losses determined from birds fed an N-free diet. Results indicated a substantial advantage of WF pea over CF pea as a source of digestible Lys, Met, Cys, His, Ile, Leu, Phe, Val, Asp and Glu for 14-day-old chickens. With the exception of methionine and cysteine, there was no significant difference between these two cultivars in the SID values of AA in 28-day-old birds. The protease increased SID of nutritionally essential AA from WF pea-based diet at both ages, and from CF pea-based diet in chickens aged 28 days. In conclusion, the SID coefficients of indispensable AA determined at 14 days of age in low-tannin WF peas are not applicable to the formulation of grower-type feeds containing seeds of CF cultivars.
