The digestibility of crude nutrients in horses. 1. Methods of determining digestibility     

R Fuchs  H Militz  M Hoffmann 《Archives of Animal Nutrition》1987,37(3):235-246

The ascertainment of the digestibility of crude nutrients in rations for horses requires the inclusion of movement-based performance as influencing factor. Under the consideration of this requirement, indicator methods gain significance in comparison with the standard method of collecting faeces completely. In two experiments the digestion of the crude nutrients in rations for horses was tested according to the standard method (complete collection of faeces) and the indicator method 4 N HCl-insoluble ash). According to the indicator method the digestibility of crude nutrients was slightly higher, the differences to the values of the standard method were statistically insignificant. Under consideration of the inhomogeneity of horse faeces and the possibility of doing without the complete collection of faeces, the indicator method with 4 N HCl-insoluble ash is to be preferred to the standard method. The analysis of air-dried faeces connected with the indicator method resulted in improved reproducibility due to the significantly better homogeneity. A recommendation is made for carrying out digestibility experiments with horses, in which the 4 N HCl indicator method is used.  相似文献   

Urea utilization in growing lambs. 6. N balance with 15N urea     

M Ulbrich  S Nikitin  C Geissler  M Hoffmann 《Archives of Animal Nutrition》1988,38(1):53-65

Lambs of an age of 2 or 4 months and of an average live weight of 14.7 and 27.4 kg resp. received rations consisting of 44% cereals, 46% dried sugar beet pulp, 6% wheat starch, 2% urea and 2% mineral-vitamin mixture. The crude protein content was 17.1 and 15.9% resp. in the dry matter, that of native crude protein 10.6 and 9.4% resp. During a 6-day N balance period 8 and 16 g 15N urea resp. with a 15N excess (15N') of 9.26 and 9.40 atom-% were fed orally instead of commercial feeding urea. There were no significant differences between the two age groups with regard to the digestibility of the organic matter and the crude nutrients. The average N balance of 372 +/- 85 mg/kg LW 0.75/day were in the intermediate range of N retention capacity and accounted for 26 +/- 5% of the consumed N. N retention in per cent. was slightly lower in younger lambs. Projections of urea utilization in a quasi stationary state resulted in an efficiency of the utilization of 33 +/- 4%. The dismembering of the lambs at the end of the main period showed between 0.02 and 0.22 atom-% 15N' in the total N, TCA precipitable N and amino acid N of the meat. At between 0.24 and 0.38 atom-% 15N' they were highest in the heart and jaw muscles. The quota of 15N' amounts found in the total N of the meat were 10.6 +/- 3% of the 15N-intake and 20.1 +/- 5.1% of the 15N' amount remaining in the body. The bones contained 7.7 +/- 1.7% and the fleece 7.9 +/- 3.1% of the 15N'-intake. Generally seen, the total N and urea utilization was slightly lower in younger lambs than in older ones.  相似文献

Epidemiology of periodontal disease in poodles     

Th. Hoffmann  P. Gaengler 《The Journal of small animal practice》1996,37(7):309-316

The periodontal condition of 123 poodles was assessed using the parameters of depth of gum pocket, attachment level, bleeding on probing, and plaque and calculus accumulation. No dogs were free of periodontal disease. The number of deep pockets and dramatic loss of attachment ranged from 0.1 teeth in young dogs to 4.2 teeth in old animals. A sixfold increase in deep pocketing took place in dogs between the ages of six and seven, followed by a twofold increase in the number of teeth missing in dogs within the 10 to 11 year age group. First premolars, incisors and second molars were at highest risk. No correlation between dietary conditions and disease incidence could be detected. It is concluded that, by concentrating their diagnostic efforts on those age groups and types of teeth at highest risk, clinicians could improve the effectiveness of their treatment interventions.  相似文献   

The effect of energy concentration and source on the use of feed protein and NPN in lambs. 3. Allantoin excretion and microbial protein synthesis     

M Ulbrich  C Geissler  S M Bassuny  F Borowiec  M Hoffmann 《Archives of Animal Nutrition》1989,39(6):553-562

In an N balance experiment with male crossbreeding lambs at an age of 3 ... 4 months four different rations were given differing in energy concentration (high greater than 700 EFU cattle/kg DM and low less than 650 EFU cattle/kg DM) and in the energy source (sugar, starch or crude fibre) with crude protein intake being almost equal. The rations contained 2% urea. Microbial protein synthesis in the rumen was assessed according to ROTH and KIRCHGESSNER (1978) (1), RYS et al. (1975) (2) and BICKEL-BAUMANN and LANDIS (1986) (3) on the basis of allantoin excretion in urine. The highest ruminal protein synthesis quotas were 868 ... 921 mg protein N per kg LW0.75 in (2). In (3) 723 ... 766 mg protein N/kg LW0.75 were synthesized. From the 15N labelling of the supplemented urea and the excreted allantoin it could be calculated that 26 ... 40% of the microbial protein resulted from the urea-N of the ration. Despite a high crude protein content of the ration of between 16 and 17% in the DM and a relation of NPN: pure protein of 0.95 the utilization of the NPN in the ration was relatively high but slightly lower than the utilization of pure protein. The variants with higher energy concentration showed as a tendency higher allantoin excretion in spite of slightly lower dry matter intake and a slightly higher NPN utilization than the variants with lower energy concentration.  相似文献

The nutrient and energy disposition of growing lambs. 2. Results of slaughter and animal carcass analysis     

H P Fix  M Brützke  I Peschke  M Hoffmann 《Archives of Animal Nutrition》1988,38(4):327-341

A total of 90 lambs (fattening hybrids of either sex of three different genetic constructions and male merino meat sheep) were butchered at the beginning (9...16 kg live weight) or at the end (29...33 kg live weight) of a growth experiment. Total body and the meat of carcass, cutlet and loin were analysed. Significant differences between the genotypes could only proved in the crude ash content. The female animals showed a significantly higher content of fat, dry matter and energy as well as a significantly lower content of crude ash--at the end of the experiment also of protein--in the total body than the male animals. The content of nutrients and energy in the total body could be much more precisely derived regressively from the corresponding content values in the meat of the carcass than from the values of cutlet and loin.  相似文献
