The physiology of the thyroid gland has become of increasing interest to us because of the observations made by Graham3 and the confirmation by others that the feeding of dried thyroid gland or the injection of thyroxine would dramatically increase the milk yield and fat secretion of many dairy cows. The effect of thyroxine upon the rate of growth and body type and conformation has been suggest...

Antimicrobial resistance of Escherichia coli to modern beta-lactam antibiotics due to the production of extended-spectrum beta-lactamases (ESBL) and/or plasmid-mediated AmpC beta-lactamases (AmpC) represents an emerging and increasing resistance problem that dramatically limits therapeutic options in both human and veterinary medicine. The presence of ESBL/AmpC genes in commensal E. coli from f...

OBJECTIVE This study was conducted to compare growth performance, blood components and carcass traits by two feeding systems (concentrate with roughage separately [CON] vs total mixed ration [TMR]) in Hanwoo steers, and to learn the relationship between blood components during fattening or finishing phases and carcass traits in Hanwoo steers. METHODS Sixty steers aged 8 months were allotted t...

twenty four male lambs divided into four groups and were allocated to 90, 105, 120 and 135 days of fattening periods.at the end of each fattening period, lambs were slaughtered. the percentage of cold carcass on the basis of empty body weight in the mentioned periods were 57.0 ± 0.94, 57.5 ±1.7, 59.9 ±3.3 and 62.2 ±4.4,respectively(p

this experiment was conducted using 172 male lambs of ghezel and mehraban breeds for two periods of 60 and 80 days. two systems of fattening were studied. the first group of lambs entered feedlot boxes immediately after weaning (spring) but the second group being fed on pasture, entered the experiment approximately 4 months later (autumn). fattening periods were 60 and 80 days. the average wean...

Block matching along epipolar lines is the core of most stereovision algorithms in geographic information systems. The usual distances between blocks are the sum of squared distances in the block (SSD) or the correlation. These distances suffer the adhesion (or fattening) effect, a defect by which the center of the block inherits the disparity of the more contrasted pixels in the block. This re...

To understand the different selection procedures used in Germany it is necessary to explain the structure of pig breeding and production. The commercial fattening pigs are either produced by traditional herdbook organisations or by commercial breeding companies. While in Bavaria 90 % of all fattening pigs are single crosses with Pietrain as sire and Landrace as dam, in the northern part of Germ...

Data of 5,390 Merino lambs born from 1986 to 2007 (approximately 6.9 generations) were used to derive genetic parameters and trends for age-specific and overall lamb survival on the underlying scale, as well as for lamb birth weight, using Gibbs sampling. The majority of lambs were descended from lines that were divergently selected for the ability of ewes to rear multiples. The line selected i...

This paper deals with the study of the spectral components of Lamb waves generated in thin aluminium plate using pulsed Nd-YAG laser and detected using a He-Ne Laser Heterodyne interferometer. Laser generation of Lamb waves leads to simultaneous generation of various frequency component as well as multiple Lamb wave modes. The Lamb wave signals are successfully and comprehensively analyzed usin...
