Piglets diet supplemented with amino acid valine

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…

Wheat in feed for broilers

“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…

Field inspections 1999

The field inspections for seed certification of cereals, hybrid maize, grain legumes, red clover and forage grasses were carried out on 8‘945 ha in 2000. In cereals 92,5% of the registered area was admitted during field inspection, 2,1% was refused and 5.4% was withdrawn from field inspection. Hail damage, presence of other cereals, and varietal…

Trivalent Chromium – Interactions with the diets

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…

Plastic silos – Recommendations for safe operation

Material fatigue and/or overloading can cause a collapse of tower silos of glass fiber reinforced plastic. As the silos are designed mainly for the relatively coarse-fibred grass and maize silages, the danger of collapse increases when the silo is filled with products of a high density, such as sugar beet pulp, coarse meal of maize…

Behaviour of dairy cows with self-feeding at a silo

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…

Selenium status of the Swiss population and the agriculture

The natural environmental conditions in Switzerland are not in favor of an adequate selenium supply to humans and animals. However, the results of different studies (food, blood serum) demonstrate a sufficient selenium status of the population. The reasons are selenium-rich wheat imported from North-America as well as the supplementation of feeds for domestic animals. It…

Amount and composition of manure produced by fattening beef cattle

To furnish a reliable basis for the revision of the guide values on manure production and composition of fattening beef cattle, 37 balance experiments were conducted on 13 Swiss farms. The daily growth rate of the animals varied between 1100 and 1500 grams. The mean annual production of slurry per fattening beef place was 7.5…

Nutrient and pollutant content of compost

The quantity of compost produced in Switzerland has been assessed, and the quality of individual composts has been determined and compared to the legal standards describing a minimal quality of compost. A last comparable study has been made in 1988. Today, more than 450’000 tons of fresh material are composted in more than 200 compost…

Decimal Code for growth stages of hemp

A decimal code for growth of hemp (Cannabis sativa L.) is presented. The life cycle is divided into four principal stages: germination and emergence, vegetative stage, flowering and seed formation, senescence. Each principal stage is subdivided into secondary stages. The practical use of the code is discussed with particular reference to different yield components.<br><br>Un codice…

New problem plants and weeds in Switzerland – a threat to agriculture and natural areas?

The increasing number of naturalized nonnative (exotic) plant species is a significant component of global change in most regions of the world. In agricultural areas new exotics may cause new weed problems and may demand for new control measures. In natural areas newly established exotic species may become dominant and suppress native vegetation, thus threatening…

New Swiss cultivars of perennial ryegrass: Cavia, Arvicola, Lacerta

Three new Swiss cultivars of perennial ryegrass have been inscribed recently into the list of recommended cultivars of forage plants: Cavia (diploid, early), Arvicola (tetraploid, very early) and Lacerta (tetraploid, early). They were mainly derived from the same genetic resources (Swiss ecotypes collected in 1972) as our very early cultivar Arion. As compared to Arion,…

The use of silage additives in pressed pulp silage

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.…

Recommended vitamin A, E an D for piglets

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…

Control of seed-borne snow mould (Gerlachia nivalis) of winter wheat with warm water

Warm water treatment of seeds of winter wheat cv. Runal under practical conditions was compared with a laboratory warm water treatment, a chemical seed dressing, and an untreated control in field and laboratory experiments in 1997-1998. The treatment under practical conditions was performed as follows: seed lots (350 kg) were dipped into water (45°C) for…

Control of Septoria tritici based on ELISA-thresholds

In Europe Septoria tritici (ST) is actually one of the most important diseases in wheat. The data from 12 Swiss field trials from 1993 to 1998 with different cultivars were analyzed. In 1/3 out of the cases a treatment against ST was economically justified. This situation is an ideal prerequisite to use intervention thresholds. From…

Market demands on Golden Delicious Apples

Sugar content and firmness are two important factors determining eating quality of apples. Sensory analysis with a trained panel confirmed that sweetness, sourness, fruitiness and firmness can be predicted by instrumental measurements such as total soluble solids (refractometer), titratable acidity and firmness measurements by penetrometer. Tests with consumers indicated that Golden Delicious of acceptable eating…
