“…The CP content of ECSL seemed markedly higher than unprocessed lupins (26.6% and 29.5%), which may be due to the release of peptides from cell walls during the extrusion process. The CP value of sweet lupins in this study was lower than the value of 35.5% reported by Brand et al (1992). One possible reason could be the addition of molasses in this study, which would also explain the lower DM of lupins in this study as molasses (Kalori 3000, Yara Animal Nutrition) has a high hygroscopicity.…”

The effect of the extrusion of canola oilcake meal (COM) and crushed sweet lupins (CSL) with molasses on the dry matter (DM) and crude protein (CP) degradability was determined in situ. Locally sourced (SOILL Moorreesburg, South Africa) COM and CSL, with the addition of 6% molasses, were extruded at a maximum temperature of 116 °C. A total of six Dohne Merino wethers (± 80 kg), fitted with rumen cannula, were used in this trial. Samples in polyester bags (5 g) were incubated in the rumen of the sheep at intervals of 0, 2, 4, 8, 16, 24, and 48 h. The DM and CP disappearances from the rumen were determined and degradability parameters were estimated. Extrusion increased the potentially degradable CP fraction by 43.5%. At each outflow rate, the average CP effective degradability of COM (68.2%) was lower than that of CSL (78.0%). Extrusion substantially lowered the CP effective degradability for both protein sources at every outflow rate tested. The biggest effect was seen at 0.08/h, where effective degradation was lowered by 25.6%. Extrusion with molasses was found to modify ruminal degradation parameters of both canola oilcake meal and crushed sweet lupins, while also decreasing the effective rumen degradation, especially at faster outflow rates. Thereby, the rumen undegradable protein fraction was increased by 85.4%. This study shows that COM and CSL extruded with 6% molasses can substantially increase RUP.

Kikuyu pasture was grazed continuously for 12 months by 20 dry and 40 producing South African Mutton Merino (SAMM) and Merino ewes at a stocking density of 23 ewes ha -1 . Supplementary sweet lupin seed was supplied to one group of producing ewes of each breed during pregnancy and lactation at a rate of 0.5% of the liveweights of the ewes. Rumen fluid samples for the determination of pH, volatile fatty acids (VFA), and ammonia-nitrogen (NH 3 -N) were collected from rumen-fistulated wethers corresponding to the periods of late pregnancy and early lactation of ewes. Rumen NH3-N concentrations (8.7 mg 100 ml -1 and 5.4 mg 100 ml -1 ) were low during both periods of sampling. Rumen VFA concentrations (12.3 mmol 100 ml -1 and 9.2 mmol 100 ml -1 )were within normal ranges. Supplementation significantly increased blood urea concentration of ewes. Supplemented ewes lost less weight than the unsupplemented ewes (P 0.02) during the experimental period. Pregnancy (P 0.001) as well as lactation (P 0.0001) reduced greasy wool production. Supplementation increased birthweight of lambs by 21% (P 0.0007). Rumen parameters indicated no severe deficiency in either protein or energy intake. A lack of response in wool and lamb growth due to lupin supplementation was primarily A98055Received 2 1 October 1998; accepted 16 July 1999 ascribed to a high CP degradability of lupin seed. Production of the different breeds was in accordance with their respective genetic potential.
