“…This is in agreement with results from research in soybean oil (Jørgensen et al 1993;Kil et al 2011), corn oil (Kil et al 2010) and rapeseed oil (Jørgensen et al 1996). The TTTD and the endogenous loss of AEE for soybean oil was also determined in the present experiment.…”

This experiment was conducted to determine the effect of inclusion level and type of basal diet on the digestible (DE) and metabolisable (ME) energy content of soybean oil and its digestibility when fed to growing pigs. Thirty-six barrows (Duroc · Landrace · Yorkshire weighing 34.2 AE 3.8 kg) were randomly allotted to a 2 · 3 factorial arrangement involving two basal diets and three levels of soybean oil (0%, 5% and 10%). One basal diet was based on corn and soybean meal. The other basal diet was based on corn starch and casein. The barrows were housed in individual metabolism crates to facilitate separate collection of faeces and urine, and were fed the assigned test diets at 4% of initial bodyweight per day. A 5-day total collection of faeces and urine followed a 7-day diet-adaptation period. The DE and ME contents of soybean oil were significantly affected by the dietary inclusion level (P < 0.05), but not by the type of basal diet. The DE contents of soybean oil at the 5% and 10% inclusion level were 34.99 and 37.63 MJ/kg, respectively, for the corn-soybean meal basal diet and 33.72 and 35.21 MJ/kg, respectively, for the corn starch-casein basal diet. The respective corresponding values for ME were 33.91, 37.07, 33.06 and 34.83 MJ/kg. The DE values calculated from regression equation were 38.05 and 37.85 MJ/kg, respectively, for corn-soybean meal and corn starch-casein basal diet. The DE value calculated from regression equation was greater than the values determined from the difference method for corn starch-casein basal diet. The value of endogenous loss for acidhydrolysed ether extract was greater (P < 0.05) for corn-soybean meal basal diet than for corn starch-casein (13.06 g/kg of dry matter intake for corn-soybean meal basal diet and 1.37 g/kg of dry matter intake for corn starch-casein basal diet, respectively). The values of the true total tract digestibility and apparent total tract digestibility of soybean oil determined from the corn-soybean meal basal diet were not different from those determined from the corn starch-casein basal diet (true total tract digestibility: 97.1% and 95.4%; apparent total tract digestibility: 95.8% and 95.3%, respectively). In conclusion, the DE and ME values of soybean oil are affected by its inclusion level but not by basal diet. The type of basal diet did not affect the digestibility of soybean oil, but affected the endogenous loss of acid-hydrolysed ether extract for soybean oil.

BACKGROUND: The aim of this study was to identify health-related biomarkers affected by different growth conditions of plant foods. Rats were fed balanced diets composed of vegetables and rapeseed oil from three different cultivation systems ('LIminusP', low fertiliser input, without pesticides; 'LIplusP', low fertiliser input, with pesticides; and 'HIplusP', high fertiliser input, with pesticides) chosen to cover a broad range of management options, rather than representing actual food production systems.

“…The collection period for pregnant sows lasted for 5 days. In the middle of each collection period (days 3–4) the metabolic cage was wheeled into a respiration chamber for measuring the gas exchange for 2 × 24 h using the open‐air system, as described by Jørgensen et al, (1996). Respiration experiments were performed approximately on days 30, 61, 80 and 104 of pregnancy.…”

The present study was performed to quantify the energy and nutrient metabolism of pregnant sows fed high (HP) or low (LP) dietary protein [18.3 vs. 13.5% of dry matter (DM)]. A total of nine sows (four on HP and five on LP diet) were subjected to balance and respiration trials four times during their second pregnancy (approximately on days 30, 61, 80 and 104 of gestation). The digestibility of protein (83.0 vs. 79.9) (p < 0.01) and energy (84.9 vs. 83.7%) (p < 0.05) was higher for the HP diet. Daily intake of metabolizable energy (ME) and retained energy (RE) were similar for the two groups, with an average of 28.37 MJ ME and 3.94 MJ RE, respectively. Heat production (HE) measured according to the respiratory quotient (RQ) and carbon-nitrogen (CN) method was similar (464 vs. 454 kJ/kg 0.75/day, respectively). Sows fed HP retained more energy in protein (3.33 vs. 2.00 MJ/day) (p < 0.001) and tended to retain less energy in fat (1.59 vs. 2.50 MJ/day) than LP sows. Retained nitrogen (N) (22.3 vs. 13.4 g/day) (p < 0.001) and utilization of N (retained/digested) (45.2 vs. 38.1%) was higher for HP sows compared with LP sows. In late pregnancy, retained N, retained fat, HE and oxidation of carbohydrates increased, while oxidation of fat was reduced to zero. In conclusion, both diets provided adequate N for retention in maternal tissue and conception products. In spite of the lower utilization of N in LP sows, the N excretion was depressed by 5.6 g/day compared with HP sows, because of the lower N intake.
