| Three diets were prepared with ingredients cultivated by each of three different farming systems, low input of fertilizer without pesticides (LIminusP), low input of fertilizer and high input of pesticides (LIplusP), and high input of fertilizer and high input of pesticides (HIplusP). A preference test was conducted to investigate whether rats could distinguish among the three iso-energetic and iso-nitrogeneous diets, and the influence of the mothers’ diet was accordingly studied with regard to the food choice of the progeny. The experimental diets contained potatoes, carrots, peas, green kales, apples, and rapeseed oil and were formulated to meet the NRC requirements for growing rats by mixing. Rats were weaned from dams, which had been fed one of the... |

| I det økologiske husdyrhold skal dyrene have adgang til grovfoder. Grovfoderet skal ikke udgøre en bestemt andel af foderet, men være dagligt tilgængeligt for alle dyr. Grovfoderet tilfredsstiller dyrenes adfærdsmæssige behov mht. mæthed og rodeadfærd, og formodes at have en gavnlig virkning på deres sundhedstilstand. Ønsket om en øget økologisk svineproduktion påvirker økosystemets næringsstofbalance, hvorfor det er vigtigt at kende til svinenes bidrag hertil. Der er ikke særlig megen viden om, hvor godt svin udnytter grovfoder, fordi forskningen i mange år har været fokuseret på koncentrerede fodermidler, der giver maksimal foderudnyttelse og vækst. I projektet, som beskrives i det følgende, er der lavet nogle basale undersøgelser af, hvordan... |

| The effect of three iso-energetic and iso-nitrogeneous diets composed of ingredients originating from three different cultivation systems (“Organic”, low input of fertilizer without pesticides; “Minimally fertilised”, low input of fertilizer and high input of pesticides, “Conventional”, high input of fertilizer and high input of pesticides) was investigated with respect to several physiological responses and biomarkers of health using a rat model. The diets were optimized according to the nutritional requirements of rats, except for a high content of fat. The diets consisted of equal proportions of potatoes, carrots, peas, green kale, apples, and rapeseed oil, which were grown according to three different cultivation systems. Even though most of the... |

| The present investigation aimed to study the ileal and fecal digestibility of three forages (Clover grass, Clover grass silage and Pea-Barley silage) supplemented to a basal diet. A total of 24 pigs, adapted to eating forages by supplementing a basal feed with clover grass silage from weaning, were fitted with a T-cannula at the terminal ileum at approximate 30 kg LW. For each of the three types of forage, two balance trials with 4 weeks interval were carried out. Two pigs in each test were fed the basal diet while 6 others were fed the basal diet plus forage throughout the whole experiment. The intake of forages was relative low and quite variable and accounted on average for only 10-12 % of the daily dry matter intake. Ileal digestibility estimated by... |

| Mussels cultured on lines for nine months and harvested in March were boiled to remove shells and processed into a dry meal or a silage acidified by formic acid. Starfish meal was prepared from starfish caught in May, and a starfish juice fraction was obtained by pressing fresh starfish. Commercial fish silage from farmed salmon was also included in the experiment. The standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) was evaluated in a Latin square design with pigs (initial weight 39.3 kg) fitted with a simple T-cannula in the terminal ileum. Diets contained 131–162 g CP/kg and 5 g chromic oxide/kg. Endogenous losses of protein and AA were estimated by feeding an N-free diet. On a dry matter (DM) basis, mussel meal... |

| Mange forbrugere anser økologiske fødevarer for at være af bedre kvalitet, sundere og mere næringsrige end fødevarer produceret ved konventionelle metoder. Men forskning på området, der kan fastslå en sådan sammenhæng, er enten ikke tilstede eller mangelfuld. Ingen forskningsresultater, der kan be- eller afkræfte forbrugernes opfattelse. |

| The aim of the study was to measure protein utilization and energy value of dried apple, carrot, kale, pea, and potato prepared for human consumption and grown in 2 consecutive years with 3 different farming systems: (1) low input of fertilizer without pesticides (LIminusP), (2) low input of fertilizers and high input of pesticides (LIplusP), (3) and high input of fertilizers and high input of pesticides (HIplusP). In addition, the study goal was to verify the nutritional values, taking into consideration the physiologic state. In experiment 1, the nutritive values, including protein digestibility-corrected amino acid score, were determined in single ingredients in trials with young rats (3-4 weeks) as recommended by the Food and Agriculture Organization... |

| A preference test was conducted to investigate whether rats could distinguish among three iso-energetic and iso-nitrogeneous human diets prepared with ingredients cultivated by each of three different farming strategies: LIminusP: low input of feritlizer without pesticides, LIplusP: lowinput of fertilicer and high input of pesticides and LHplusP: high input of fertilizer and high input of pesticides. The experimental diets were formulated to meet the NRC requirements for growing rats by mixing potatoes, carrots, peas, green kales, apples, and rapeseed oil. For five days, rats (N=27) had free access to each of the three diets, and consumption of each of the diets was recorded daily. Thereafter, rats were offered a standard laboratory chow until the test... |

| Environmental as well as cultivation factors may greatly influence the chemical composition of plants. The main factors affecting chemical composition of foodstuff is level and type of fertilizer (conventional and organic cultivation systems), location or soiltype and year of harvest. Organic foods are defined as products which are produced under controlled cultivation conditions characterized by the absence of synthetic fertilizers and very restricted use of pesticides. Dietary carbohydrates constitute a major fraction of most feedstuffs and can be divided according to glycosidic linkage into sugars (mono- and disaccharides), oligosaccharides, starch and non-starch polysaccharides (NSP). The bulk of disaccharides and starch will be broken down by the... |

| Total energy expenditure or heat production is comprised of basal metabolic rate, thermic effect of food, and physical activity. Physical activity is the most variable and easily altered component of total heat production. Physical activity is influenced by a number of biological parameters i.e. diet, genetics, age, and gender. The diet components of the macro as well as micronutrients and other components (secondary metabolites) associated with a diet could contribute to the well being of the animal and cause variation in physical activity. In order to investigate physical activity as a parameter to differentiate diets based on conventional or organic grown carrots the total heat production and physical activity was measured in a rat model. The... |

| Food preference tests represent an approach in food quality research, taking advantage of the instinctive feeding behavior of animals by allowing them to choose between food samples. A great number of investigations using laboratory rats concerning essential and/or dangerous contents are based on this method and have shown its effectiveness. The selection of food is influenced to some degree by smell and taste, but mostly by wholesomeness and need. In the present study a preference test was used in order to test eventual selective differences among rats with regard to same composition, but cultivated in three different systems. The experimental diets were formulated to meet the NRC requirements for rats by mixing 40% of freeze dried carrots with an... |

| In 2 experiments, 10 gilts (30 kg initial liveweight) were given a basal diet with fresh or frozen/thawed clover-grass, clover-grass silage or whole-crop pea-barley silage. The faecal digestibility of gross energy (GE), DM, organic matter (OM), dietary fibre (DF) and CP were measured. The 3 roughages, leaves and stems of clover-grass and the basal diets were also tested for in vitro OM digestibility. Roughage intake was similar in both experiments and the average proportion of roughage ingested was 18-19% of DM. There were no differences between fresh and frozen/thawed clover-grass nutrient digestibility values. Glucose (cellulose) and xylose were the main constituents of the non-starch polysaccharides (NSP) in the roughages, with whole-crop pea-barley... |
