“…Despite the decrease in the "A" fraction in the extruded peas, the ED of the peas did not present any differences as a result of extrusion (P>0.05). Extrusion reduced the solubility and the fractional degradation rate in the lupin, which was also observed by Rémond et al (2003) and Ramos-Morales et al (2010). In this study, the ED obtained in lupins was lower than that in the abovementioned works, which may be attributed to the use of dehulled lupin instead of whole grain.…”

C. Barchiesi, P. Williams, and A. Velásquez. 2018. Extrusion of lupin and pea decrease the ruminal degradability improving true ileal digestibility of crude protein. Cienc. Inv. Agr. 45(3): 231-239. The aim of this work was to evaluate the effect of the extrusion of dehulled lupins (Lupinus albus L.) and peas (Pisum sativum L.) on the ruminal degradability and intestinal digestibility of their protein contents. Ruminal degradability was evaluated in situ in the rumens of two fistulated cows. The true ileal crude protein (CP) digestibility was evaluated via a bioassay with Sprague Dawley laboratory rats as the animal model. Extrusion caused soluble fraction decreases in both feeds (P<0.05), with a 29 % decrease in the extruded dehulled lupins (EDL) and a 59 % decrease in the extruded peas (EP). The degradable fraction (B) in EP increased by 19 % compared to that in raw peas (RP) (P<0.05), and there was no effect of extrusion on the degradable fraction in lupins (P>0.05). Extrusion decreased the effective degradability (ED) of lupins by 12 % (P<0.05). Moreover, in EP, extrusion presented no effect on the ED (P>0.05). The extrusion process had a greater impact on the reduction of the effective degradability in lupins than it did in peas. Nevertheless, extrusion increased the true ileal CP digestibility of the ruminal postfermentation residues in both feeds.

“…Ipharraguerre and Clark (2005) pointed out that the supply of microbial protein could be balanced by using protein sources that are resistant to ruminal degradation. The animal would thus acquire an additional supply of N. In a previous study the degradability of the crude protein of each legume seed was analysed (Ramos Morales et al., 2008b). Taking into account the soluble fraction (40.7, 51.9, 42.0 and 38.7% for L, FB, BV and V, respectively) and overall the effective degradability values (87.5, 86.2, 82,4 and 79.8% for L, FB, BV and V, respectively), the legumes used may be considered as a source of degradable protein for ruminal micro‐organisms and, therefore, for microbial protein synthesis (González and Andrés, 2003).…”

“…We believe the tannin content might determine the degradability of the dry matter or of the crude protein in each legume supplied. Comparison of the effective degradability of the protein in each legume with its tannin content (Ramos Morales et al, 2008b) showed that there is no relation between these values.…”

“…Earlier studies dealing with the legume seeds in our group fundamentally consisted of the characterization of four legume seeds of local varieties: lupins ( Lupinus albus , moltolupa variety), faba beans ( Vicia faba , alameda variety), bitter vetch ( Vicia ervilia , moro variety) and vetch ( Vicia sativa , filon variety). In these studies, the chemical composition, the ruminal degradability of their dry matter and crude protein, the possible correction of these values for particle loss, the intestinal digestibility of the non‐degradable protein fraction, the amino acid profile of their protein and the proportion of the latter that is non‐degradable was determined (Ramos Morales et al., 2008a,b). The present study focused on the utilization of N and energy of diets in which 30% of the protein was derived from one of the legume seeds studied.…”

The N and energy utilization of diets with different legume seeds was analysed in lactating goats. Four isonitrogenous and isoenergetic diets were used and in each case 30% of the protein was supplied by one of four different legume seeds: lupins (L), faba beans (FB), bitter vetch (BV) and vetch (V). A group of eight Granadina goats, allocated to a replicated 4 × 4 Latin Square, were used. The N and energy utilization of the different diets may be considered adequate; milk N/intake N was approximately 0.20, milk N/N balance was approximately 0.50 and milk energy/metabolizable energy was approximately 0.30. Under similar N and energy intakes, faecal and urinary excretion of N and the quantities in milk did not vary significantly. However, the partition of the N balance between milk production and deposit within the body varied depending on the diet. Although this N available to the metabolism was the highest for the FB diet, the quantity of this directed to milk was the lowest. Finally, the faecal and urinary excretion with respect to the quantity directed to milk production did not vary significantly among the different diets.

The synchronized provision of dietary nitrogenous and energetic compounds to the rumen at the appropriate time and in appropriate amounts increases the efficiency of microbial mass synthesis (Hall and Weimer, 2007) and can be used to minimize pollution emissions (Reynolds and Kristensen, 2008). Grass silage is widely used in dairy cow feeding. Diets based on grass silage are characterized by a high level of rapidly degraded crude protein in the rumen and for the successful nutritional synchrony, the supply of corresponding fermented carbohydrates is of great importance for microbial The study was conducted to find out the effects of the type of non-fibre carbohydrates (NFC) included in grass silage-based diets on in sacco degradability of dry matter (DM), crude protein (CP) and neutral detergent fibre (NDF) of lupin (Lupinus angustifolius L. cv. Sonet) seeds ground to different particle sizes. Measurements of degradability were carried out as a 3 × 2 × 3 × 3 experimental design of treatments with carbohydrates included in diets as primary sources of NFC (starch vs. pectin vs. sugars), particle size of ground seeds (1.0 vs. 5.7 mm), period of the trial (1 vs. 2 vs. 3) and cannulated cow (1 vs. 2 vs. 3). The variables of in sacco kinetics were calculated according to the equations of Ørskov and McDonald (1979) for degradation data corrected for the particle loss. The protein value of lupin seeds for ruminants was expressed as the amount of protein digested in the small intestine, and it was estimated based on the obtained characteristics of degradability. Under our experimental conditions, the type of NFC included in the grass silage-based diets and the particle size of seeds affected the course and extent of rumen degradation of lupin seed nutrients. Higher values of DM and CP degradation were estimated after 8 and 16 h of incubation (P < 0.05). The higher rate of degradation of insoluble but potentially degradable fractions (P < 0.05) and higher effective degradability (P < 0.05) were found out in the rumen of cows receiving diets containing sucrose compared with cows receiving diets containing starch. In comparison with starch and pectin, sucrose decreased the amount of protein digested in the small intestine (P < 0.05). The results suggested that the type of NFC determined ruminal microbial activity. An enlargement of the lupin seed particle size from 1.0 to 5.7 mm decreased the rumen degradability of lupin seed nutrients (P < 0.05) and increased the amount of protein digested in the small intestine (P < 0.05). The results indicated that feeding standards should consider the influence of the grinding level of lupin seeds in order to assess their nutritional value.
