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...

Scientific investigations of production losses in pigs due to roundworms are rarely conducted in commercial farms, despite the fact that this information is needed to decide whether anthelmintic treatment is cost-effective or not. Therefore, the aim of our study was to compare performance in fattening pigs treated or not treated for Ascaris suum infections. Two Danish pig farms producing fatten...

We investigated the effects of temperature on photoperiodic induction of the phenologies linked with migration (body fattening and premigratory night-time restlessness, Zugunruhe) and reproduction (testicular maturation) in the migratory blackheaded bunting. Birds were exposed for four weeks to near-threshold photoperiods required to induce testicular growth (11.5 L:12.5 D and 12 L:12 D) or for...

An investigation was conducted to estimate approximate production and assess the marketing of mud crab in the south-western region of Bangladesh. Crab culture was done by hardening and fattening collected from the natural source. Most of the fattening farms were 0.2 to 2 acres. Fattening and hardening period varied from 10 to 30 days. The Sundarban mangrove, tidal rivers, estuaries, canals, shr...

The aim of the present study was to investigate the relationships between temperament score and blood cortisol concentration, as well as energy metabolic parameters (glucose, triglyceride, non-esterified fatty acid and cholesterol) in Tsigai lambs during fattening. The temperament of lambs was assessed (scored) by a temperament score test, where the behaviour of animals was evaluated in a 5-sco...

Chlamydial infections in pigs are associated with respiratory disease, diarrhea, conjunctivitis and other pathologies. The aim of this study was to define the prevalence of Chlamydiaceae in Swiss fattening pigs by applying sensitive and specific detection methods and to correlate prior antibiotic treatment and farm related factors with differences in prevalence. Conjunctival and fecal swabs wer...
