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…

In two balance trials with 15 and 16 lactating Saanen goats (model animal for cows), the effects of different sodium cloride (NaCl) supplies and roughage to concentrate ratios on performance and metabolism were investigated. The NaCl supply levels ranged from 100 to 200 and 300 % of Swiss recommendations (RAP, 1999). The tested roughage to…

In the years 1996 to 1998 we investigated the influence of the dry matter content on fermentation and on aerobic stability in grass silage. Therefore, we ensiled forage of the same plots with two different dry matter contents in tower silos in 1996 and in square bales in 1997 and 1998. In some cases we…

In 1999, we investigated the efficacy of six silage additives, containing lactic acid bacteria, which should promote the main fermentation. The trials were carried out in small-scale silos with a mixture of lucerne and cocksfoot. Forage of the first and also second cut was ensiled at two different dry matter levels (about 20 and 30…

In a five week long trial with a total of 128 Large White piglets weighing 10 to 30 kg, the effect of the feed additive Diamond V XP Yeast Culture, a yeast-fermented cereal mixture, on growth rate, feed intake, feed conversion and medical treatment was examined. The 2-factorial design comprised two control treatments, a negative…

1968 one-day old chicks of Isa brown hybrid were kept in an aviary system (Natura Typ AZ-187), which was divided in four groups of 492 animals each. At day 1, half of the animals were beak-trimmed by hot cut, whereas the beaks of the other chicks remained intact. At the beginning of week 16, 1500…

The goals of these trials were to investigate the effects of different dietary amino acid concentrations and valine:lysine ratios on piglet performance and health. Two 4-week trials with 90 weaned piglets each were conducted. Both trials were set up as a block design with 3 treatments and 6 replicates per treatment (a total of 18…

“No two cows are alike in their behavioural characteristics. These individual differences become evident in the reactions and the sensitivity of cows towards environmental changes already in daily life situations. There is evidence that such behavioural characteristics predispose an animal’s stress responsiveness. We assessed two methods in order to quantify individual characteristics: (1) we asked…

The possibility to replace the milk substitute in the diet of the veal calf by cereals was studied in three feeding trials with 224 calves. The aim of the study was to reduce the production costs and to improve the image of veal production. The animals of the experimental group received either rolled barley or…

Three experiments with growing-finishing pigs were performed to evaluate the effects of dietary trivalent chromium (Cr) under certain feeding conditions. The results of the first study indicated that an amount of 200 mg Cr / t feedstuff (ppb) is sufficient since daily gain was increased when 200 ppb Cr was added compared to the control…

Self-feeding at a horizontal silo adjacent to the exercise yard is a labour-saving alternative in winter feeding. In an experiment with forty dairy cows divided into two groups, the impact of the animal/feeding place ratio (1,5:1, 2:1 and 2,5:1) on social and feeding behaviour of the cows was investigated. We also varied the distance between…

In a trial we investigated the influence of the filling time on silage quality. On the one hand we ensiled the pressed pulp after the transport from the sugar factory on the same day and on the other hand, ensiling was carried out after two days. In all variants we used 9 m3 silos and…

In a trial we investigated the efficacy of different silage additives. Besides seven chemical products we also tested an inoculant, which was applied in liquid and solid form, as well as a product which contained a combination of lactic acid bacteria and chemical substances. The tests were carried out in laboratory silos in two series.…

During 34 days 4 x 16 female and castrated male piglets of the large white breed received a complete feed with the following vitamin A-, E- and D-concentrations in two consecutive series: Treatment A: 4000 IE, 16 mg, 500 IE, treatment B: 6500 IE, 16 mg, 1100 IE, treatment C: 10000 IE, 25 mg, 1500…
