Ammonia concentrations, litter quality, performance and some welfare parameters of broilers kept on different bedding materials

ABSTRACT 1. Litter quality has been related to broiler performance, behaviour, welfare, dust and ammonia (NH3) emissions. Drier litter leads to a reduction in NH3 emissions and reduces the formation of foot- and hock lesions. However, maintaining good litter quality is often challenging. This study investigated the effects of different bedding materials on litter quality and NH3 concentrations at litter level, broiler performance, foot- and hock lesions, plumage cleanliness and breast skin irritation. 2. A total of 2160 Ross 308 male broilers were randomly assigned to 36 floor pens. There were six replications for each of the following six litter treatments: wood shavings, flax, peat, maize silage, chopped wheat straw and flax pellets. 3. For the total period, the highest feed intake and body weight was obtained for broilers housed on peat. The NH3 concentrations measured at litter level was highest for peat and chopped wheat straw at 36 d of age and numerically the lowest for flax at 30 and 36 d of age. Maize silage remained friable, but did not result in lower NH3 concentrations compared to wood shavings. Chopped wheat straw and wood shavings gave rise to the highest incidence of foot lesions at 38 d of age, while broilers kept on flax, peat, maize silage and flax pellets had the lowest incidence of foot lesions at the end of the rearing period. 4. The results of the current study suggest a complicated relationship between the type of bedding material, litter conditions and NH3 volatilised from the litter.

The foot deformity versus postural control in females aged over 65 years.

Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. The study included 116 women aged 65-90 years. The mean age was 70.6 ± 8.4 years and BMI 29.1 ± 3.4 m/kg2. The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.

The structure and probable mechanism of evolutionary formation of the foot in piciform birds (Aves: Piciformes)

The foot structure of piciform and coraciiform birds is examined in detail. Certain similarity in foot structure between woodpeckers and woodhoopoes is shown and provides the basis for the model of the evolutionary formation of the zygodactyl foot. It is shown that African mousebirds and the Madagascan Leptosomus discolor are probably the closest relatives of piciforms. A brief review of fossil groups presumably belonging to the piciform stem is provided.

The Exit Failure of Cemented Carbide Face Milling Cutters Part II —s Testing of Commercial Cutters

Earlier work by Pekelharing has shown that in interrupted cutting with cemented carbide cutting tools on steel workpieces the exit failure due to the formation of feet is the major cause of tool failure. A typical industrial operation with these characteristics is face milling. The sensitiviness of a number of commercial milling tools when cutting Ck45 steel was investigated. For a certain range of positions of the cutter relative to the exit face of the workpiece the number of cuts which can be taken until tool failure occurs is nearly zero. This is called the “dangerous zone of exit conditions”. The position of the boundaries between safe and dangerous exit conditions are used to evaluate the sensitiviness for exit failure of milling cutters. The influence of tooldesign and cutting conditions on these boundaries is discussed.

玩具の歩きのつ機構

Toys on the market which go on foot are usually nothing but a miniature copy of machines. And so they have little or no appeal to those who have gone far beyond the mechanical princiles involved in those toys.The toys the author presents here should challenge your curiocity because of their design. The reason is that kinematic chains to which the toys belong have more than two degrees of freedom of motion which does not prevent them from moving as if they have only one.This phenomenon seems to inform us that a machine can be free from the condition known as “Zwanglauf”.In this paper the author treats the following articles : 1. Introduction, 2. Fundamental concept, 3. Formation of feet, 4. Coxistruction and 5. Conclusion.
