“…Courtheyn et al (2002) reported that providing glucocorticoids in low dosages increases feed intake and ADG and improves the feed conversion ratio. In our study, however, although the use of dexamethasone significantly increased ADG, feed intake for both Control and treated animals was similar, and therefore this gain in the weight of the bulls treated might be related to an improved feed efficiency.…”

“…In addition to anti-inflammatory and immunosuppressive activities, synthetic glucocorticoids such as dexamethasone affect gluconeogenesis, glycogen deposition, protein and calcium metabolism (Courtheyn et al, 2002). The effect of these substances on carbohydrate metabolism led to their use as growth promoters in beef cattle fattening, and in the United States they are still used to increase carcass fatness and meat marbling (Corah et al, 1995).…”

“…The effect of these substances on carbohydrate metabolism led to their use as growth promoters in beef cattle fattening, and in the United States they are still used to increase carcass fatness and meat marbling (Corah et al, 1995). Although the use of corticosteroids as growth promoters is banned in Europe, illegal administration (Courtheyn et al, 2002) in order to increase feed intake, water retention and live weight gain (Istasse et al, 1989) is highly suspected. Beef farmers first began administering dexamethasone in combination with other substances such as b-agonists, at low dosages, in order to exploit additional or synergic growth effects and perhaps conceal its use from public service veterinarians conducting checks at the slaughterhouse (Courtheyn et al, 2002).…”

“…Dexamethasone and other corticosteroids are now becoming the most commonly used growth promoters, however, because their detection in organic matrices does not necessarily testify the use for non-therapeutic reasons. Dexamethasone alone has also been administered recently in low dosages because field experience and scientific results showed that high dosage inhibits growth and leads to muscle atrophy (Istasse et al, 1989;Corah et al, 1995;Courtheyn et al, 2002).…”

The study investigated the effects of prolonged oral administration of dexamethasone at a low daily dosage of 0.75 mg/head per day (Dexa) on beef cattle productive traits, behaviour and meat quality. In all, 14 finishing Marchigiana bulls were used in a trial that begun 56 days prior to slaughter, of which six bulls received treatment from day 5 to day 53, whereas the remaining animals were used for Control. The animals treated showed an increased average daily gain (1515 v. 1177 g/head per day; P , 0.05; s.e.d. 5 48.54) and improved warm carcass dressing percentage (60.8% v. 59.7%; P , 0.05; s.e.d. 5 0.32). Behavioural observation did not permit a clear distinction between treated and Control animals since feeding and social behaviour were similar in both groups. The bulls treated spent less time lying (16.5% v. 34.6%; P , 0.05; s.e.d. 5 4.38) and grooming (6.7% v. 11.9%; P , 0.05; s.e.d. 5 1.23), and this may indicate poorer welfare. No evidence of treatment was observed in other carcass traits, and redness was the only meat quality parameter slightly affected by corticosteroid administration.

Meat Inspection and Control in the Slaughterhouse

View full text Add to dashboard Cite

The strong development of science in the nineteenth century prompted the need to develop practical solutions to prevent diseases caused by parasites and bacteria in humans based on the findings of Louis Pasteur, Robert Koch, Rudolph Virchow and Friedrich A. Zenker. It was shown in the 1860s that Trichinella was transmitted to humans through contaminated pork meat. Later, many bacterial and other parasitic diseases were shown to transmit to humans through meat. Due to these findings, veterinary medicine grew in importance and it was increasingly demanded that veterinarians be in charge of public health and that the importance of veterinary education be increased in the society. The role of veterinarians became significant in meat inspection. Later, veterinary public health and food hygiene became an essential part of veterinary education. Robert von Ostertag, a German veterinarian, wrote an extensive handbook on meat inspection in 1892 and created the scientific basis for meat inspection. The book was translated into English in 1904. The proportion of meat originating from diseased animals was high in the nineteenth century and the quality of meat was poor. A huge improvement was achieved through the organization of meat inspection and the development of the scientific basis of meat inspection. Meat inspection has been a success story and it has been the most important programme in improving food safety. Huge steps were taken to prevent the transmission of pathogenic organisms and contagious diseases from animals to humans. Meat inspection
