Cows only achieve their full yield potential in an environment where they feel comfortable. The milking parlour plays an essential part in shaping this environment. Even when milking machines are installed according to ISO 5707, operators of new milking parlours often notice not only the advantages, but find signs indicative of unfavourable conditions: Cows are…

Two different pasture utilisation systems – rotational versus continuous – were compared during the grazing seasons of the years 1995 – 98, each with a herd of 24 dairy cows of mixed age and stage of lactation, including dry cows. The two herds were split again into two groups each which were fed different supplements…

In a trial with 4 × 500 growing pullets of Bovans brown hybrid, the effect of access to litter material (wood shavings) from day 1 on (E1) in comparison to offering litter from day 10 on (E10) was compared up to week of age 16. Pullets were kept in an aviary system of Harmony 3A-type.…

In Switzerland, the landscape is to be enriched and the diversity of species shall be promoted with the preservation of meadows, which are managed extensively. The forage of such meadows, particularly that of the first cut, has a low nutritional value. Different trials enabled us to test the silage quality of such forage. Over a…

Until now, the milk yield of dairy cows has steadily been increasing. Consequently, their nutritional requirements are also increasing. This requires a higher proportion of concentrates in their ration. It is a trend which leads to intensive production systems with high needs for energy and nitrogen. This may not be brought in line with an…

Science aims at putting facts into context. Science attempts to define laws that underlie these facts and to clear its purview. Scientific work requires good techniques and methods. A real scientist is prepared to discard a hypothesis if it is in contradiction to the facts. A good scientist not only examines the results of an…

In foreign beef production herds F1-crossbred cows between beef x dairy breed are common. The goal of this investigation, carried out on the ETH research stations, was to compare different production parameters of 20 F1 crossbreed cows Angus x Holstein and 22 pure-bred Angus cows. All of the 42 animals, mated with Angus, were calving…

The efficacy of the three silage additives Conservit liquid, Kofa Grain pH5 and Lupro-Grain on aerobic stability during unloading and feed out was investigated in grass and also maize silage in comparison to a treatment without additives and a treatment with propionic acid (Luprosil). All three silage additives are chemical products. The trials with grass…

2000 one-day old and non beak-trimmed chicks of H&N hybrid (white) were kept in an aviary system (Natura 400 AZ-187) which was divided into four groups of 500 animals each. Two groups were vaccinated with Paracox-8® on day 8 whereas the others were given a coccidiostat in the diet up to week 12. At the…

Recently, pressed pulps are also baled for silage. From March to August 2000 we investigated at four different dates the quality of eight bales, which were made in 1999. As soon as the bales were opened we took samples and subsequently every day a part of about 7 cm was fed to cows. 7 and…

In Switzerland +Natura Beef® + is the brand name for suckler cow calves which will be slaughtered at weaning at the age of 10 months. The goal of this investigation was to compare production efficiency of medium sized dual purpose Simmental cows and small sized and strong by muscled Angus cows. The whole herd was…

In 2000, we tested the efficacy of the two silage additives Naturasil (concentrate) and Topsilage. Both products are containing lactic acid bacteria meant to promote the main fermentation in silages. The trials were carried out in small-scale silos with a mixture of lucerne and cocksfoot. Forage of the first and also of the second cut…

Dietary conjugated linoleic acids (CLA) have been reported to profoundly affect lipid metabolism, to act as a repartitioning agent and to promote body weight gain. We resume in the present review experimental data assessed with pigs (sows, piglets, finishing pigs) fed either a CLA or sunflower oil fortified diet. The CLA source (59 g CLA/100g…

On a group of 95 heifers of the Fleckvieh / Red Holstein and Brown Swiss breeds, growth, fertility and first lactation culling decisions werde studied. Calf rearing, feeding and housing were according to current practice in Switzerland. The heifers were first bred relatively late, at 20,3 months average. When subdivided by calving age, the growth…

In order to gather data about the quality of wheat, especially for broiler feeding, a study covering the 1999 Swiss harvest was performed with the help of the major interested circles. Wheat quality data is essentially based on their baking ability, which criteria are used to classify the lots. Wheat of good baking quality in…

In a feeding trial set up as a 2 x 2 factorial design, the effect of 30 g and 40 g of potassium per kg of DM in a diet containing 100 % or 200 % of Swiss sodium recommendations on mineral metabolism and on selected parameters of 12 dairy cows was investigated. The desired…

The effects of supplementing the diet with either milk or whey during the first few days after weaning at four to six weeks of age on disease incidence and growth performance was studied in herd with a high incidence of coliform diarrhoea and enterotoxaemia. In the first trial the 90 piglets of the two experimental…

The efficacy of two silage additives on aerobic stability was investigated in maize silage in comparison to a treatment without additive and a treatment with propionic acid. The maize was harvested at two different dry matter levels (31 and 37 % dry matter) and ensiled in 1.5 litre laboratory scale silos. 7 days before the…

Total microbial counts from 2400 samples of goat milk from the Bernese Oberland and Central Switzerland are not normally distributed. Arithmetic means of the number of colony forming units (cfu/ml) are higher than in cow milk whereas the medians are lower. From 1995 until 1997 the producers managed to increase steadily the ratio of class…
