“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.…

66 newborn piglets of 11 litters were allotted to 6 treatments: 285 mg iron (Fe) as Fe methionine orally either within 12 h after birth or on the 2nd day (FeM1, FeM2), 290 mg Fe as Fe dextran orally either within 12 h after birth or on the 2nd day (FeD1, FeD2), 200 or 100…

Seven different types of concrete, three types of asphaltic concrete and three types of mastic asphalt were exposed to silage juice of maize during 9 weeks. The samples were mounted on transmission chains making an alternation between immersion and drying possible. The measuring of the weight losses showed that the resistance of the concrete could…

In a feeding trial at the Swiss Federal Research Station for Animal Production (RAP), a total of 48 fattening pigs were given daily access (7 to 9 hrs) to an uncultivated plot infected with Ascaris suum eggs to investigate the influence of the parasitic exposure and subsequent infection on the amino acid requirements. Set up…

The efficacy of the silage additive All-Sil Granular, an inoculant to promote the main fermentation was tested. The trials were carried out in small-scale silos with a mixture of lucerne and cocksfoot. Forage of the first and second cut was ensiled at two different dry matter levels (about 20 and 30 % dry matter). A…

Dairy cows kept in a cubicle housing system were offered round bales of either hay or grass silage in the exercise yard using two types of racks. Feeding them part of their daily ration outside resulted in doubling the time the cows spent in the exercise yard. Rank order had no significant effect on exercise…

In a field survey of the Swiss College for Agriculture and a complementary trial at the Swiss Federal Research Station for Animal Production (RAP), the mineral content of grass from continuous short grass pastures and rotational pastures was analyzed. The order of magnitude of the mineral content of investigated continuous short grass pastures and rotational…

In a series of feeding trials with veal calves, the effect of dietary Cu levels on the Cu concentration in calf livers was investigated. The examined rations contained per kg of dry matter (DM) 2, 6, 8, 10 and 30 mg of Cu. The copper was added as sulfate. Up to a live weight of…

In a pig herd with a high prevalence of oedema disease, the preventive effect of a pelleted diet with a crude fibre content of 10 % which contained beet pulp, apple pomace and carob beans was tested in weaned piglets with a weaning weight of 11 kg. The 80 weaned piglets of the diet group…

In a joint project of the companies Hoffmann-la Roche, Micarna SA and the Swiss Federal Research Station for Animal Production (RAP), the effect of an additional vitamin E supplementation of 100 mg/kg in a standard diet on pork quality parameters and purchasing habits of consumers was investigated. The control treatment consisted of a standard diet…

In a five week feeding trial with 160 rearing piglets, the effect of the multiactive probiotic growth promoter Sanobiotice® S was investigated alone or combined with 50 mg of Carbadox in comparison to a negative and positive control (50 mg of Carbadox) diet.<br>Only the treatment factor Carbadox increased growth rates. Due to differing animal losses,…

In a trial with 10 x 180 laying hens (LSL white), the effect of the exclusion of animal proteins from layer diets (diets B and C) was tested in comparison to a standard diet (diet A) from week 21 to week 72. Essential amino acids (EAA) were optimised on total base in diets A and…

Vitamin E is an antioxidant. Various papers report on positive effects of vitamin E supplementations on meat color and oxidation stability thus improving meat quality.<br>In a feeding trial with fattening pigs, the control diet contained, according to Swiss feeding recommendations, 40 mg of vitamin E per kg of feed. The experimental diet was supplemented with…

The efficacy of different silage additives on aerobic stability was investigated in maize silage. The maize was harvested at two different dry matter levels (31 and 39 % dry matter) and ensiled in 1.5 liter laboratory scale silos. During the storage period different air stress conditions were made.<br>The silageadditives Lact-A-Pro containing lactic and propionic acid…

In 1981 an authorisation procedure for the sale of housing systems for farm animals was introduced in Switzerland. Authorisation shall only be granted if such systems provide proper living conditions for the animals. Requests for authorisations are handled at the two Centres for Proper Housing in Animal Production of the Swiss Federal Veterinary Office, which…

A study was conducted to determine the effects of dietary safflower oil and/or tallow with or without vitamin E supplementation (0, 100 or 200 mg/kg) in a feed for laying hens, on laying performance and traits of internal quality of eggs. The feed was based on wheat and corn. A total of 54 laying hens…

Feed characteristics can influence behaviour in laying hens. Twelve hens (ISA-Brown, 56th to 68t th week of age) were used to analyse feeding patterns. Three diets, different in structure (fine vs. coarse particle size distribution) and composition (isoenergetic replacement of starch by fibre and fat) were tested. Diurnal distributions of number, size and duration of…

Japanese quails (Coturnix japonica) kept for egg and meat production are typically housed in battery cages. In such intensive systems several welfare problems occur. Part of the results of a research project that aimed at developing an alternative housing system are presented. Groups of eight to nine quails were observed in Semi-natural outdoor aviaries. The…
