Fattening performance of steers of six beef breeds

The fattening performance of 138 steers of the beef breeds Angus (AN), Simmental (SI), Charolais (CH), Limousin (LI), Blonde d’Aquitaine (BL) and Piemontese (PI) was investigated over two series. The basic ration fed ad libitum consisted of grass and maize silage in a proportion of 1:2 in the dry matter, which was supplemented with concentrate.…

DOC-trial: farming system and silage quality

Between 1996 and 1998 we investigated the influence of a bio-dynamic, a bio-organic and a conventional farming system on grass silage quality. For all treatments the same grass-clover-mixture was sown at the same place, the plots were fertilized differently depending on the farming system. Two different fertilizer levels per system were applied. The plots were…

Milking without stress

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…

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…

Crossbreds beef x dairy breed as suckler cows

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…

Effects of vaccination against coccidiosis in comparison to the use of dietary coccidiostats on the development and the performance of growing pullets and laying hens

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…

Production parameters in a suckler cow system with Simmental and Angus cows on alpine pastures

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…

Testing silage additives 2000

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…
