“…Western blotting analysis showed that whey protein exerted no effect on LXR␣ protein levels. These results were consistent with those of a previous study, showing that whey-based diets fed to weaned piglets for 72 d exerted no effect on LXRs either in the liver or in adipose tissues (40).…”

Whey protein is associated with improvement of metabolic syndrome. This study aimed to evaluate effects of whey protein on atherosclerosis in ApoE mice. Male ApoE mice were fed with a high-fat/cholesterol diet (HFCD), or HFCD supplemented with 10% or 20% whey protein for 18 wk. At the end of experiment, serum lipid profiles and inflammatory cytokines were assayed. Livers were examined using HE staining and Oil Red O staining. Aortas were used for en face and cryosection analyses to observe aortic lesions. Western blotting analysis was used to assess relative protein expression of cholesterol metabolism in the liver and aorta. No significant differences were observed in body weight or food intake among the three groups. Liver examination demonstrated decreased lipid droplets and cholesterol content in the whey-protein-supplemented groups. En face lesion of the aorta revealed a 21.51% and 31.78% lesion reduction in the HFCD supplemented with 10% and 20% whey groups, respectively. Decreased lesion was also observed in cryosection analysis. Whey protein significantly increased the serum high-density lipoprotein cholesterol level by 46.43% and 67.86%. The 20% whey protein significantly decreased serum IL-6 (a proinflammatory cytokine) by 70.99% and increased serum IL-10 (an anti-inflammatory cytokine) by 83.35%. Whey protein potently decreased lipogenic enzymes (ACC and FAS) in the liver and NF-κB expression in the liver and aorta. Whey protein significantly increased protein expression of two major cholesterol transporters (ABCA1 and ABCG1) in the liver and aorta. Thus, chronic whey protein supplementation can improve HFCD-induced atherosclerosis in ApoE null mice by regulating circulating lipid and inflammatory cytokines and increasing expressions of ABCA1 and ABCG1.

“…Blood cholesterol level is largely determined by dietary fat and cholesterol intake, also high intakes of crude protein have been found to downregulate blood cholesterol (Theodorou et al, 2015). The general level of crude protein intake was higher in experiment 1 than in experiment 2, corresponding to lower blood cholesterol levels in experiment 1 as compared with experiment 2.…”

Organically produced pork occupies only a small niche in the European meat market, with one of the main reasons being the shortage of locally produced high-quality protein sources. In an effort to promote currently under-utilized protein sources, two feeding trials were conducted with grass pea seeds as feed for weaned piglets. The grass pea (Lathyrus sativus L.) is a hardy grain legume that produces protein-rich seeds, but, as other grain legumes, it contains several anti-nutritive compounds. Apart from trypsin inhibitors and tannins, it also contains the neurotoxin β-N-oxalyl-L-α,β-diaminopropionic acid (ODAP) which may cause nerve damage in farm animals as well as humans. The content of both trypsin inhibitors and ODAP can be greatly reduced by hydrothermal treatment; therefore both raw and hydrothermally treated grass pea seeds were used in the two feeding trials. Diets were fed to 152 and 144 piglets [crosses of (Pietrain × Duroc) × (Landrace × Large White)] respectively, during their rearing phase directly after weaning. In experiment 1, a control diet was compared with two diets containing 10 and 20% raw grass pea seeds, plus one diet with 20% treated grass pea seeds, respectively (as fed basis). In experiment 2, a control diet was compared with one diet containing 20% raw grass pea seeds and two diets containing 20 and 30% treated grass pea seeds, respectively (as fed basis). Grass pea seeds contained 265 and 271 g kg−1 crude protein (as fed basis) in the first and second experiment, respectively, and had an amino acid profile similar to peas (Pisum sativum), including relatively low contents of methionine and cysteine. Hydrothermally treated grass pea seeds were found to be a valuable protein source that was well accepted by piglets. At an inclusion rate of 20–30% in diets, feed intake and daily weight gain of piglets was very similar to that of the control treatment. However, including 20% raw grass pea seeds had a significant negative effect on feed intake in experiment 1 and on daily weight gain in experiment 2. Therefore, hydrothermal treatment of grass pea seeds is recommended prior to feeding to piglets.

“…Whey powder has been supplied in swine diets ( Mahan, 1993 ; Yang et al , 2007 ). Several studies have been performed regarding the basic principle of dietary effect of whey protein on animals, including growth performance, nutrient digestibility, and its metabolic process ( Burnell et al , 1987 ; Grinstead et al , 2000 ; Kim et al , 2015a ; Theodorou et al , 2015 ). Ahmed et al (2014) noted that a positive effect of dietary whey protein on beef quality such as extended shelf-life of beef.…”

The objective of this study was to determine the effect of dietary supplementation with whey powder (WP, 1g/kg feed) from weaning to slaughter (150 d) on dry-aged loin quality of pigs. Fifty-eight pigs were randomly divided into two dietary treatment groups (seven replications of four pigs per treatments). Basal diet with 0.1% whey powder was supplied to the WP group. Basal diet was used for the control group (CON). Diet whey protein did not appear to influence the moisture or protein contents. However, ash and fat contents were significantly (p<0.05) decreased in the WP group compared to the control group. Drip loss was significantly (p<0.05) lower in the WP group than that of the control group. Increasing redness with decreasing lightness was found in the inner loin of the WP group. Calcium and iron contents in the WP group were significantly higher than those in the control group. Protein degradation was higher in the WP group than that in the control group (p<0.05), whereas shear force was lower in the WP group than that in the control group (p<0.05). In conclusion, the basal diet supplemented with 0.1% whey powder influence negatively the lipid oxidation of meat whereas the texture property and mineral composition of meat from whey powder fed pigs are developed.
