Yeast products as feed additives in weaning piglets
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…
Effect of beak trimming on brown growing pullets and laying hens
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…
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 In cereals 92,5% of the registered area was admitted during field inspection, 2,1% was refused and 5.4% was withdrawn from field inspection.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…
Cereals instead of milk substitute in the diet of veal calves
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…
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…
Influence of single passes with high wheel load on a structured, unploughed sandy loam soil
In a field experiment, a sandy loam was subjected to single passes with a sugar beet harvester at two different soil water potentials and two different hopper fillings. The moist plot responded to a wheel load of 11,23 t with an increase in bulk density and pre-consolidation pressure as well as with a decrease in…
