In total, 196 samples of six categories of forage (n = 111) and eight categories of non-forage feedstuffs (n = 85) were analysed for chemical composition and in vitro gas production (GP). Lucerne hay as main forage source showed a stable average quality (mean +/- standard deviation: crude protein 179 +/- 19 g . kg(-1) dry matter (DM); metabolizable energy 8.9 +/- 0.6 MJ . kg(-1) DM) and its fibre fraction content was the most similar to browse leaves. Depending on the type, browse showed large variation in composition and fermentation. Supplementation of polyethylene glycol as tannin-binding agent, led to a significant increase of GP in leaves and bark. According to application, non-forage feeds differed in energy and crude protein contents, and fibre fractions. The chemical composition and GP of dehydrated lucerne pellets were very similar to lucerne hay, whereas other compound feeds were balanced. Characteristics of sugar beet pulp would ensure a beneficial fermentation when compared to other high-energy feedstuffs. A dietary substitution of fruits and vegetables with sugar beet pulp led to less distinct peaks in the theoretical GP of whole rations over 24 h. Available nutritive recommendations for giraffes in captivity were generally confirmed; however, the protein delivering capacity of lucerne hay was suspected to be undervalued. Comprehensive analyses of leaves and bark resulted in additional information on temperate browse."],["dc.identifier.isi","000378188400005"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41855"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Kielanowski Inst Animal Physiology Nutrition"],["dc.relation.issn","1230-1388"],["dc.title","Chemical composition and fermentation characteristics of feedstuffs for giraffes (Giraffa camelopardalis) in German zoos"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Clinicians tend to believe that the ever-growing teeth of rabbits and rodents have a constant growth that needs to be worn down by the mastication of an appropriate diet. In this study, we tested the effect of four different pelleted diets of increasing abrasiveness [due to both internal (phytoliths) and external abrasives (sand)] or whole grass hay fed for 2weeks each in random order to 16 guinea pigs on incisor growth and wear, and tooth length of incisors and cheek teeth. There was a positive correlation between wear and growth of incisors. Tooth lengths depended both on internal and external abrasives, but only upper incisors were additionally affected by the feeding of whole hay. Diet effects were most prominent in anterior cheek teeth, in particular M1 and m1. Cheek tooth angle did not become shallower with decreasing diet abrasiveness, suggesting that a lack of dietary abrasiveness does not cause the typical bridge formation' of anterior cheek teeth frequently observed in guinea pigs. The findings suggest that other factors than diet abrasiveness, such as mineral imbalances and in particular hereditary malocclusion, are more likely causes for dental problems observed in this species."],["dc.identifier.doi","10.1111/jpn.12226"],["dc.identifier.isi","000353360500021"],["dc.identifier.pmid","25041439"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37058"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1439-0396"],["dc.relation.issn","0931-2439"],["dc.title","Tooth length and incisal wear and growth in guinea pigs (Cavia porcellus) fed diets of different abrasiveness"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Data were collected on ten dairy farms. In each farm, blood samples were taken from ten cows on four test days (2, 4, 9 and 11), resulting in 400 samples. The reference method was the BHBA concentration in blood serum (BHBALAB). Four different devices that measure BHBA in whole blood were tested. The thresholds applied for identifying subclinical ketosis were ≥1.0, ≥1.2 and ≥1.4 mmol/L in blood serum. The BHBALAB was assigned in three classes: low—≤0.9 mmol/L; high—>0.9 mmol/L; and total—all values unclassified. Due to initial negative effects on the health and performance of cows with BHBA levels ≥0.9 mmol/L, this cut-off was chosen. The Passing–Bablok regression revealed different constant as well as absolute biases for each device in the aforementioned classes. The area under the receiver operating characteristics curve indicated highly accurate results, with 94–97% accuracy levels. As an overall conclusion, the performance of the devices was good and supports their use by farmers for the detection of subclinical ketotic cows in their herds."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2021"],["dc.identifier.doi","10.3390/dairy2040052"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/111669"],["dc.language.iso","en"],["dc.relation.eissn","2624-862X"],["dc.relation.issn","2624-862X"],["dc.relation.orgunit","Department für Nutztierwissenschaften"],["dc.rights","CC BY 4.0"],["dc.title","Accuracy of Subclinical Ketosis Detection with Rapid Test Methods for BHBA in Blood in Commercial Dairy Farms"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Because of the importance of ingesting food, this behaviour makes up a large part of the daily routine of mammalian and avian herbivores, since they have to ingest large amounts of fibrous forage to meet their daily energy demands. Hence, they have to solve the dilemma of conflicting interests in their daily activities between foraging, social behaviour, sleep or predator avoidance. In this study, the role that body mass (BM) plays in this context was quantified and mammals and birds were compared regarding the influence of BM on instantaneous food intake rate (IFIR) (the first minutes of a meal), bite size (BS) and bite rate (BR). Because birds do not chew their food, it was hypothesised that they can increase their IFIR above the upper limit of similar-sized mammals which chew their food. Combining our own findings with literature, results showed that there is no difference between mammals and birds regarding IFIR, BS and BR. It was shown that IFIR (mammals BM0.95, birds BM0.82) and BS (mammals BM0.83, birds BM0.87) increase with increasing BM. Moreover, the factor 'non-chewing' does not increase the IFIR of birds."],["dc.description.sponsorship","DFG; DFG Research Unit FOR 533 [166]"],["dc.identifier.doi","10.1007/s10344-014-0877-1"],["dc.identifier.isi","000348219700010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/38095"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1439-0574"],["dc.relation.issn","1612-4642"],["dc.title","Food intake rates of herbivorous mammals and birds and the influence of body mass"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
