The aim of this study was to evaluate the effect of a supplementation diet for hens consisting of dried basil herb and flowers of calendula and dandelion for color, carotenoid content, iron-induced oxidative stability, and sensory properties of egg yolk compared with commercial pigment (control) and marigold flower. The plant parts were supplemented in diets at two levels: 1% and 3%. In response to dietary content, yolks from all diets differed in carotenoid profile (p < 0.001). The 3% supplementation level resulted in a similar total carotenoid content as the control (21.25 vs. 21.79 μg/g), but by 3-fold lower compared to the 3% marigold (66.95 μg/g). The tested plants did not achieve yolk color fan values as the control (13.47) or 3% marigold (11.47), and among them, calendula had the highest values (9.73). Despite the low carotenoid content in diets supplemented with basil herb, iron-induced malondialdehyde (MDA) concentration was low as for marigold (on average 106.83 vs. 92.68 ng/g after 250 min). The treatments differed in sensory color scores for fresh and hard-boiled yolks and flavor while other sensory properties were similar. In conclusion, the supplementation of plants in a hen diet may result in yolks containing carotenoids and other compounds showing a high antioxidant effect.

The Relationship

Medical progress has reduced the mortality from infectious diseases in most countries, but allergic diseases have become more prevalent worldwide over the same period, especially in industrialized countries. This has prompted speculation that modern lifestyles have altered the relationship between heredity and environment so as to promote development of an atopic phenotype when exposure to infection decreases. A healthy uterine microenvironment is known to favor Th2 lymphocyte development. However, some evidence suggests that persistence of the Th2 pattern of immunity directs the developing organism's immune response towards a long-lasting atopic phenotype. Even though the outcome also depends on other factors (such as infection, functional state of the intestinal microflora, and exposure to environmental allergens at times critical to development), it seems that the immune system during the perinatal period is responsive to interventions that are no longer effective in adulthood. We have reviewed the literature accessible through Medline to identify recent advances in the prevention of allergic disease through interventions in the fetal-maternal relationship. Diet seems to have a significant impact on the immunological profile of the pregnant uterus, as well as on the postnatal development of allergic disease in the offspring, as suggested by the effects of probiotic bacteria and by manipulations of the dietary content of polyunsaturated fatty acids and antioxidants. This highlights the need for further studies, in order to define the best intervention methods, the most appropriate time interval and the individuals who will most likely benefit from them.

Swine Diets

Seed from Lathyrus sativus L., with a low content of β-N-oxalyl-L-α, β-diamino-propionic acid (ODAP), was evaluated as an ingredient (LM) in swine diets. The first experiment involved 45 pigs fed LM, containing 27% protein (CP) and 3 g ODAP kg−1, as 0, 10, 20, 30 and 40% of starter diets (20% CP) over a 6-wk period. In exp. 2, two types of LM (0.9 and 2.7 g ODAP kg−1) were each included as 0, 10, 20 and 30 of mash diets fed to 84 pigs from 25 to 100 kg liveweight. The effects of pelleting and supplementation with 1 and 2 g methionine kg−1, for LM diets containing < 0.5 g ODAP kg−1, were examined in the final experiment using 80 growing-finishing pigs. Increasing the LM content above 10% of the starter diet reduced average daily gains (ADG) and feed intake (ADFI) but feed conversion (gain/feed; G:F) was unaffected (P > 0.10). In exp. 2, ADG declined as the dietary content of either LM increased. The lower-ODAP LM-fed pigs had relatively higher ADFI (P < 0.01) and ADG (P < 0.05) but slightly lower G:F (P < 0.08). Consumption of lathyrus led to higher (P < 0.01) liver and kidney weights and lower (P < 0.05) protein content in the longissimus dorsi. Pelleting the diet improved ADG (P < 0.01) and G:F (P < 0.05) but did not prevent the LM-effect on growth rates. Increasing the total sulfur amino acid content of the diet from 0.48 to 0.66% had no beneficial effect on live or carcass measurements. Using a method capable of detecting 100 ng ODAP per g fresh tissue, no residues were found in the loin muscle of LM-fed pigs. The results suggest that anti-nutritive constituents (e.g. anti-trypsin and anti-chymotrypsin), rather than ODAP, limit the potential of lathyrus seed as a feedstuff for swine.

Nutritional or dietary status and interactions between carcinogens and nutrient absorption, storage or metabolism influence carcinogenesis in many experimental animal models and probably in people. Use of dose-response data to indicate a threshold exposure for carcinogenesis must include consideration of dietary and nutritional factors that may alter the dose response. Two models in rats in which there is clear evidence of dietary or nutritional modulation of chemical carcinogenesis are mammary tumors induced by 7, 12-dimethylbenzanthracene (DMBA) or N-nitrosomethyl-urea (NMU) and hepatocarcinomas induced by many compounds. Mammary tumorigenesis is increased by increasing dietary content of some, but not all, fats. The time in tumor development at which fats act varies. Their mechanisms of action are not known but appear to include effects on the hormonal mileu and possibly mammary gland cell turnover and response to hormones. Hepatocarcinogenesis by chemicals is increased by dietary deficiency of the lipotropes methionine, choline and folate, possibly through alteration of carcinogen metabolism and increased hepatocyte DNA synthesis. The same deficiency induces cirrhosis. In humans, cirrhosis induced by alcoholism, viral hepatitis or unknown factors increases the risk for hepatocarcinoma. Alcohol-induced folate or other deficiency can be a contributory factor in the alcoholics. Infection with hepatitis B virus is increased in alcoholics and in patients with hepatocarcinoma and may be an initiating or modulating factor for tumors.

SUMMARYMammalian organs are nourished by nutrients carried by the blood circulation. These nutrients originate from diet and internal stores, and can undergo various interconversions before their eventual use as tissue fuel. Here we develop isotope tracing, mass spectrometry, and mathematical analysis methods to determine the direct sources of circulating nutrients, their interconversion rates, and eventual tissue-specific contributions to TCA cycle metabolism. Experiments with fifteen nutrient tracers enabled extensive accounting both for circulatory metabolic cycles and tissue TCA inputs, across fed and fasted mice on either high carbohydrate or ketogenic diet. We find that a majority of circulating carbon flux is carried by two major cycles: glucose-lactate and triglyceride-glycerol-fatty acid. Futile cycling through these pathways is prominent when dietary content of the associated nutrients is low, rendering internal metabolic activity robust to food choice. The presented in vivo flux quantification methods are broadly applicable to different physiological and disease states.

Fattening Pigs

Background: Methionine (Met) requirements have not been clearly established for fattening pigs due to their metabolic interrelationships and its bioavailability for protein synthesis. Objective: To determine the optimum level of regular crystalline or protected Met in pig diets from nursery to finishing. Methods: A total of 48 crossbred pigs (11.74±1.72 kg of initial body weight) were used. The treatments consisted of adding four levels (0.00, 0.05, 0.10, 0.15% in addition to dietary content) and two types of Met (regular and protected) to pig diets. Results: Nursery, Finishing I, and II pigs fed protected Met increased daily feed intake (DFI; p≤0.10). Protected Met raised daily weight gain (DWG) in nursery pigs and increased backfat thickness (BT) in nursery and grower pigs (p≤0.10). In Finishing I pigs, protected Met increased DWG and improved carcass characteristics (p≤0.10). In nursery and grower pigs, an extra 0.15% Met decreased feed:gain ratio (FGR; p≤0.10). In grower and Finishing II pigs fed extra 0.05% Met improved DWG and extra 0.10% Met reduced plasma urea concentration (p≤0.10). Conclusions: Feeding protected Met in pig diets increases DWG, DFI and BT. Increasing 0.05-0.15% Met level improves FGR, DWG, potentially reducing nitrogen excretion to the environment.
