[Data on artifical rearing of dual-purpose calves belonging to the dairy-beef type. 2. Effect of single or twice daily milk feeding and omission of Sunday milk feeding].

The authors carried out a 2x2 factor trial to investigate in which way different regimes of drinking and the feeding of a concentrate mixture at 2 levels of nutrition would affect the general development, food consumption and nutrient utilization of the calves or would influence their state of health and their behaviour in the period of milk feeding, and after weaning, up to the age of 6 months. No significant differences in the average liveweight were noted between th groups of calves that were milk fed once or twice daily and those milk fed once or twice daily with the exception of Sundays. The feeding of 2 types of concentrated food significantly influenced the liverweight of the calves only at the time of weaning. Significant differences in weight increases were only noticed with regal to the average daily weight increases until weaning, i.e. between the groups of animals receiving milk feeds twice daily, with the exception of Sundays, and the groups fed different types of concentrate mixtures. The different kinds of feeding did not influence the amount of solid food consumed by the animals, nor did it affect the level of nutrient utilization and the general behaviour of the animals. It was found that in the animals receiving milk once daily,except Sundays, the symptoms of diarrhea observed in the early phase of milk nutrition disappeared more slowly than in the outher animals.

[Artificial rearing of double purpose calves of the beef-dairy type. 1. Effects of the length of the milk-rearing period and of the amount of milk substitutes needed for the rearing of the calf].

Reducing the period of Milk rearing of calves from 90 days (time of weaning) as practised today to 50 days or 70 days (and thus reducing the amount of regenerated milk which is needed to rear the calf from 400 litres to 200 litres or 300 litres) would limit the rate of weight gains of the calves in the first 3 months of age. This delay is, within certain limits, compensated for by the calf in the growth period up to 6 months of age. Therefore, the authors believe that with cattle of the Hungarian breed "Ungarische Fleckviehrasse" weaning after 50 days and rearing the calves with 200 litres of milk seems to be possible. The method of early weaning and then feeding stock mixtures of concentrates seems to be also applicable provided that the conditions of veterinary hygiene would allow this. This, in turn, would require supplementation of the food with minerals and vitamins. Due to the results obtained supplementation of concentrate mixtures with urea for calf rearing is also possible, even under practical conditions. Aromatization of the concentrate mixtures, as practised in the present series of trials, did not substantiate the favourable results obtained by the authors in previous trials with respect to the effect of aromatics on food consumption and the development of weight gains.

Acoustic rhinometry and rhinomanometry in the evaluation of nasal patency of patients with nasal septal deviation.

The aim of the present study was to assess the clinical utility of acoustic rhinometry (AR) compared with active anterior rhinomanometry (AAR) in the evaluation of nasal patency in subjects with nasal septal deviation. Fifty patients were divided into three groups based upon the part of the nasal cavity where the septal deviation was situated (anterior: up to 2.5 cm; middle: between 2.5 and 4.5 cm; posterior: between 4.5 and 8 cm measured from the columella). The control group consisted of 15 subjects with no nasal complaints and no history of nasal disease. Inspiratory and expiratory nasal airway resistance (NAR) at 75 Pa and at 150 Pa before and after decongestion were measured by AAR. Minimal Cross-sectional Area (MCA), distance of MCA, and nasal volume (Vol) were measured before and after decongestion by AR (Rhino 2000). Subjective nasal patency was assessed by Visual Analogue Score (VAS). In the statistical analysis the deviated unilateral nasal cavities were compared with the randomly chosen unilateral nasal cavities of normal subjects. Both techniques AR and AAR were sufficiently sensitive to reveal severe deviations in the anterior nasal cavity (MCA, Volant, NAR75, NAR150, p < 0.05). The techniques were less sensitive in cases of middle and posterior deviations (MCA, Volmid, Volpost, MCAmid, MCApost, NAR75, p > 0.05). The nondecongested inspiratory and expiratory NAR at 150 Pa were the only parameter that differed from normal in cases of posterior deviations. The VAS correlated better with NAR than with MCA. MCA correlated more frequently with expiratory than with inspiratory NAR.
