Plants with moderate contents of condensed tannins are assumed to have anthelmintic Plants with moderate contents of condensed tannins are assumed to have anthelmintic properties and to improve protein supply of ruminants by reducing its ruminal degradability. In the present study, birdsfoot trefoil (Lotus corniculatus), chicory (Cychorium intybus) and sainfoin (Onobrychis viciifolia), suitable to be grown in Central Europe, were tested for their suitability as feed for ruminants. Sainfoin proved to be the most promising forage plant since it was very well accepted by the sheep and presented the highest content of utilizable crude protein as determined in vitro. Only few condensed tannins were detected in chicory. Further in vivo studies are required to...

Apparent recovery of C18 polyunsaturated fatty acids from feed in cow milk: A meta-analysis of the importance of dietary fatty acids and feeding regimens in diets without fat supplementation Organic Eprints
Khiaosa-ard, Ratchaneewan; Kreuzer, Michael; Leiber, Florian.
A meta-analysis was conducted using the results of 82 experiments (78 publications, 266 treatments) to investigate the importance of dietary C18 fatty acids (FA) and feeding regime for milk C18 FA profile and apparent recovery of selected FA relative to intake of these FA or their precursors. Feeding treatments based on lipid-supplemented diets were excluded. Feeding regimes were defined as grazing (including partial and full-time grazing, at dietary concentrate proportions from 0 to 44% dry matter (DM)), forage-based indoor feeding (> 65% forage of total DM intake, DMI) and concentrate-based indoor feeding (forage DMI ≤ 65% of DMI). Linoleic acid (LA), α-linolenic acid (ALA) and total C18 FA proportions in milk fat increased linearly with the...

Artenreiches Rauhfutter als Alleinfutter und Fettsäurenmuster der Milch Organic Eprints
Leiber, Florian; Kreuzer, Michael; Scheeder, Martin R.L.; Wettstein, Hans-Ruedi.
In two experiments it was investigated which factors to what extent determine the fatty acid composition milk when cows are grazing high alpine pastures. The influences of altitude per se, of alpine forage quality, of concentrate-free diet type and of the overall grazing effect were separated by the experimental design. The most important factor which significantly elevated the concentrations of CLA, α-linolenic acid (ALA) and n-3 PUFA in milk fat was found to be the alpine diet type, i.e. the feeding of roughage-only (as well hay as pasture of as well lowland as alpine origin) with omission of concentrates and maize. Additionally a clear positive effect of the forage quality of alpine pastures on ALA concentration in milk fat was found. The latter effect...

Auswirkungen einer frühen taktilen Behandlungauf Verhalten und stressanzeigende Parameter von Kälbern aus der Mutterkuhhaltung Organic Eprints
Probst, Johanna Karolina; Spengler Neff, Anet; Leiber, Florian; Kreuzer, Michael; Hillmann, Edna.
Die arbeitsextensive Mutterkuhhaltung hat in den letzten Jahren in der Schweiz erheblich zugenommen. Der direkte Kontakt zwischen Mensch und Tier, wie er bei der Haltung von Michkühen durch das tägliche Melken stattfindet, ist in der Mutterkuhhaltung um ein vielfaches vermindert. Eine Folge davon sind oftmals sehr scheue Tiere, die nicht selten ein aggressives Verhalten gegenüber dem Menschen zeigen. Einige Studien haben bereits gezeigt, dass eine taktile Behandlung durch den Menschen das Wohlbefinden der Tiere und gleichzeitig den Umgang mit den Menschen verbessern kann (siehe z.B.: Krohn et al., 2001, Lensink et al., 2000). In der vorliegenden Studie sollten junger Kälber aus der Mutterkuhhaltung einer taktilen Behandlung unterzogen werden. Die...

Auswirkungen eines positiven Handlings auf die Ausweichdistanz und die Fleischqualität von Mastrindern aus der Mutterkuhhaltung Organic Eprints
Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
This research investigated the effect of a handling treatment in beef cattle on stress related parameters. Ten 15 months old Limousin beef cattle (crossbreds) were divided in a handling group (HG) and a control group (KG) by pairing animals with similar avoidance distances. The back-region handlings were carried out 10 times for 8 min during 5 weeks before slaughter. Before and after all handling sessions, each animal was tested by an avoidance distance test (AWD). From each carcass, samples of M. longissimus dorsi were analysed for meat quality (cooking loss, shear force and meat colour). Differences between first and second avoidance distance test were greater in HG animals. Avoidance distance got much lower in HG animals than in KG animals. Shear force...

Buchweizen: eine Futterpflanze für Milchkühe? Organic Eprints
Amelchanka, Sergej; Brand, Daniela; Kälber, Tasja; Kreuzer, Michael; Leiber, Florian.
Buckwheat (Fagopyrum esculentum) has a high ecological value due to the long and intensive flowering as well as its favorable impact on soil fertility. However, in Europe demand for buckwheat kernels as food is low. Therefore, the question arises whether cultivation of this plant could be promoted by using it as animal feed. In the current preliminary experiment, the extent to which buckwheat, offered in different forms, is consumed by dairy cows was tested in conjunction with potential effects on milk yield. Three groups of lactating cows were fed a silage-concentrate mixture, which either contained 3 kg DM/d buckwheat kernel flour (n=4), or 2.5 kg DM/d buckwheat total plant silage (n=3) or no buckwheat compound (control; n=4). After 4 days of...

Can early handling of suckler beef calves reduce their timidity towards humans? Organic Eprints
Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
In herds of suckler beef cows the relationship between humans and animals is an important issue concerning animal handling. Unlike dairy cow herds, suckler beef herds are less used to close contact with humans. Due to low management input animals may be difficult to handle during treatments like medical care, routine handling or at slaughter house.

Chronic intermittent stress exposure and access to grass silage interact differently in their effect on behaviour, gastric health and stress physiology of entire or castrated male growing finishing pigs Organic Eprints
Holinger, Mirjam; Früh, Barbara; Stoll, Peter; Graage, Robert; Wirth, Sandra; Bruckmaier, Rupert; Prunier, Armelle; Kreuzer, Michael; Hillmann, Edna.
Entire male pigs display more aggressive and sexual behaviour. This might cause a condition of chronic stress and impair their welfare. In order to assess chronic stress in entire and castrated male pigs, as well as effects of providing grass silage as occupational and feed material on behaviour and health, we carried out a 2 × 2 × 2-factorial experiment with 147 growing-finishing pigs. Factors investigated were castration (entire/castrated), chronic intermittent social stress exposure (yes/no) and access to grass silage (yes/no), as well as their interactions. The stress exposure treatment consisted of repeated short-term confrontations and separations. We recorded different behavioural variables, circadian rhythm of salivary cortisol, response to an ACTH...

Das Weidesystem beeinflusst Schlachtleistung und Fleischqualität von gesömmerten Lämmern Organic Eprints
Willems, Helen; Werder, Cornel; Kreuzer, Michael; Leiber, Florian.
Die Sömmerungsbeiträge für Schafe sind in der Schweiz nach Weidesystem gestaffelt und bei Umtriebsweide höher als bei Standweide. In dieser Studie wurden in einem kontrollierten Alpweideversuch die in diesen beiden Weidesystemen erzielbare Mast- und Schlachtleistung sowie die Fleischqualität verglichen. Hierzu wurden 55 männliche kastrierte Lämmer (36,2±4,2 kg schwer und 27±3 Wochen alt) der Schweizer Rassen Engadinerschaf und Walliser Schwarznasenschaf einer fetten Milchkrautweide und einer Borstgrasweide jeweils mit Standweide- und Umtriebsweidesystem zugeteilt. Von jeder Rasse wurden auf jedem Vegetationstyp und Weidesystem sechs bis sieben Tiere gehalten. Bei Umtriebsweide waren Tageszuwachs, Schlachtausbeute und tendenziell die Fleischigkeit (CH-TAX)...

Die Auswirkung eines positiven Handlings auf die Ausweichdistanz und die Fleischqualität extensiv gehaltener Rinder Organic Eprints
Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
In der Studie wurde untersucht, wie sich eine Handling Methode (basierend auf TTouch®) auf extensiv gehaltene Limousin Kreuzungstiere (15 Monate alt) auswirkt. Vor Beginn des Handlings wurde der erste Ausweichdistanztest (AWD-Test) durchgeführt. Anhand dieser Ergebnisse wurden zwei Gruppen mit jeweils ähnlichen Ausweichdistanzen gebildet: eine Handlinggruppe (HG = 1♀, 4♂) und eine Kontrollgruppe (KG =2♀, 3♂). Das “head-neck-region Handling” wurde 10-mal für je 8 min innerhalb von 5 Wochen vor der Schlachtung durchgeführt und beinhaltete die Anwendung der TTouch® Methode an der Kopf-Hals Region der Tiere. Ein zweiter AWD-Test wurde nach allen Handlingsessions, kurz vor dem Schlachttermin durchgeführt. Blutserumproben wurden während des Entblutens am...

Effects of dietary sainfoin on feeding, rumination, and faecal particle composition in dairy cows Organic Eprints
Kapp, Alexandra; Kreuzer, Michael; Kaptijn, Gerdine; Leiber, Florian.
An experiment was conducted to test whether dietary sainfoin (Onobrychis viciifolia), a plant containing condensed tannins, affects feeding and rumination behaviour of dairy cows fed different roughage-only diets. Out of a herd of sixty lactating Swiss Fleckvieh cows, twenty-nine were chosen for a 6-week experiment. Cows were fed pasture, fresh cut grass and hay. During week 1 (baseline) and weeks 2-4, they had access to pasture for 4 hours during day, and received approximately 6 kg DM/day fresh grass and 4 kg DM/day hay in barn. In week 5 and 6, daily pasture allowance was 2 h; hay offer was doubled. In week 2-6, each cow individually received respectively 1 kg of pelleted feed in the morning and in the evening. Ten cows received ryegrass pellets in week...

Effects of vegetation type and breed on n-3 and n-6 fatty acid proportions in heart, lung and brain phospholipids of lambs Organic Eprints
Leiber, Florian; Willems, Helen; Werne, Steffen; Ammer, Stefanie; Kreuzer, Michael.
The known influence of forage composition on fatty acid (FA) profiles in ruminants’ meat and milk may be different for other organs. Therefore, in the present study FA profiles of phospholipids in lung tissue, heart muscle and brain (medulla oblongata) were examined in growing Engadine and Valaisian Blacknose sheep grazing 4 pastures of different botanical composition, whereof three were extensively managed natural mountain swards. An intensively managed lowland pasture represented the control. On each pasture type, 6–7 lambs of each breed (54 in total) grazed for 9 weeks and were subsequently slaughtered. Tissue samples were taken at slaughter, homogenized and analyzed for FA profiles after phospholipid extraction. Response to the diets was tissue...

Fatty acid profile of ghee derived from two genotypes (cattle–yak vs. yak) grazing different alpine Himalayan pasture sites Organic Eprints
Marquardt, Svenja; Barsila, Shanker R.; Amelchanka, Sergej L.; Devkota, N.R.; Kreuzer, Michael; Leiber, Florian.
The fatty acid (FA) profile of ghee produced from milk of cattle–yak hybrids grazing five mountain pasture sites along a high-alpine transhumance route in Nepal was analysed. Pastures differed in altitude above sea level(2600–4500 m), time period of being grazed and phytochemical composition of the swards. Additionally, a comparison of ghee from purebred yak and hybrid was performed, with samples produced at two of the sites. Pasture site had a strong effect on almost all FAs. Proportions of oleic, linoleic and a-linolenic acid in ghee were smallest on the highest pasture at 4500 m where the largest condensed tannin concentrations in the forages were found. No systematic site effects were found for c9,t11 conjugated linoleic acid and total polyunsaturated...

Gentle touching in early life reduces avoidance distance and slaughter stress in beef cattle Organic Eprints
Probst, Johanna; Spengler Neff, Anet; Leiber, Florian; Kreuzer, Michael; Hillmann, Edna.
This study investigated the effect of gentle touching applied during the early life of suckler beef calves on avoidance distance on-farm and stress reactions at the abattoir. Twentyseven Limousin crossbred calves were assigned to a treatment (n = 13) or a control group (n = 14) balanced by sex and day of birth. Gentle touching, using the TTouch© method, began on the second day post partum and was continued on the following 2 days. Additional touching was conducted on 3 non-consecutive days during the following 3 weeks in the home pen. Each treatment lasted for 10 min and was repeated once after 30 min. Individual avoidance distance was assessed 6 times. Following this test, all voluntary approaches towards the test person were recorded. All animals were...

Grass silage for growing-finishing pigs in addition to straw bedding: Effects on behaviour and gastric health Organic Eprints
Holinger, Mirjam; Früh, Barbara; Stoll, Peter; Kreuzer, Michael; Hillmann, Edna.
In organic and other enriched housing systems, straw is commonly used as enrichment material for pigs. Its positive effects on health and behavioural welfare are well known. However, potential additional impacts of roughages (other than straw) have rarely been investigated. On six organic farms, we therefore investigated how providing grass silage affects behaviour, gastric health and performance of growing-finishing pigs. Per farm, two to four pens were included in the experiment, with group sizes ranging from five to 26 pigs (total n = 368), and stocking density ranging from 1.65 to 3.50 m2 per pig during finishing. Groups were provided with either grass silage (SIL) or straw (CON) in a rack. Long-stack straw was used as bedding material in all pens....

Milk fatty acid composition of dairy cows fed greenwhole-plant buckwheat, phacelia or chicory in theirvegetative and reproductive stage Organic Eprints
Kälber, Tasja; Kreuzer, Michael; Leiber, Florian.
tThe hypothesis was tested that the phenological stage of dicotyledonous forages influencesmilk fatty acid (FA) composition of dairy cows. For this purpose buckwheat (Fagopyrum escu-lentum) and phacelia (Phacelia tanacetifolia; both in their first year of cultivation) as well aschicory (Cychorium intybus; second year) were cultivated in mixture with ryegrass (Loliummultiflorum). After 35 days of growth, feeding the green forages to 3 × 6 late lactating dairycows at ad libitum access started. The realized dietary dry matter proportions of the testplants were (vegetative and reproductive stage): buckwheat, 0.60 and 0.55; chicory, 0.70and 0.69; phacelia, 0.51 and 0.48. Experimental feeding lasted for 23, 17 and 26 days withbuckwheat, chicory and phacelia,...
