Composição centesimal e teor de colesterol na carne de eqüinos (Equus caballus, Linneaus, 1758) machos e fêmeas agrupados por peso de carcaça

Abstract

RESUMOO presente estudo foi conduzido em frigorífico comercial e as análises no Setor de Tecnologia de Carnes do Departamento de Ciências dos Alimentos da Universidade Federal de Lavras (UFLA). Com o objetivo de avaliar o efeito do sexo e categoria de peso sobre a composição centesimal e teor de colesterol, 20 eqüinos (10 machos castrados e 10 fêmeas) foram abatidos e agrupados em categorias de peso ao abate preestabelecidas, sendo: C 1 ( 88,82 a 97,88 kg); C 2 (102,20 a 115,80 kg); C 3 (129,71 a 160,69 kg); C 4 (162,80 a 236,40 kg); com 5 animais por categoria. Os músculos longissimus dorsi (LD) e semimembranosus (SM), após o abate, foram coletados e analisados: umidade, gordura, proteína e cinzas (AOAC, 1990) e o colesterol foi determinado por colorimetria (BRAGAGNOLO, 1997). O modelo estatístico foi inteiramente casualizado, em esquema fatorial 2X4, e os dados foram analisadas pelo programa estatístico SAS. O fator sexo influenciou (p<0,05) os teores de colesterol no músculo LD. As médias encontradas (em base de matéria seca natural) foram de 36,77% e 56,08% para macho e fêmea, respectivamente. Os fatores categoria de peso e sexo não influenciaram os valores de umidade, proteína, cinza e gordura, nos músculos LD e SM, cujas médias foram: cinzas 0,70% e 1,16%; umidade 75,53% e 75,83%; gordura 0,67% e 2,03%; proteína 21,63% e 22,49% , para os músculos LD e SM, respectivamente. As proporções desses constituintes químicos mostram que a carne de eqüinos obtida em abatedouro comercial apresenta alta quantidade de proteína e baixa de gordura e pode ser considerada uma carne magra.Termos para indexação: Composição centesimal; Carne; Eqüino. ABSTRACTThe present study was conducted in a packing house, with the assays being done in the Sector of Meat Technology/Food Science Department of the Universidade Federal de Lavras (UFLA). With the objective of evaluating the effect of sex and category of weight on the meat proximate composition and content of cholesterol, 20 equines (10 castrated males and 10 females) were slaughtered and grouped in pre-established categories of weight: C 1 (88.82 to 97.88 kg); C 2 (102.20 to 115.80 kg), C 3 (129.7 to 160.69 kg) and C 4 (162.80 to 236.40 kg); with 5 animals for each category. The muscles longissimus dorsi (LD) and semimembranosus (SM) were collected and analyzed for: moisture, fat, protein and ashes (AOAC, 1990) and the cholesterol was determined by colorimetry (BRAGAGNOLO, 1997). The statistical model was completely randomized, in factorial scheme 2X4, and the data were analyzed through the statistical program SAS. The factor sex influenced (p<0,05) the contents of cholesterol in LD muscle, with average values (in base of dry natural material) of 36.77% and 56.08%, for males and females, respectively. The factors category of weight and sex had no influence in the values of moisture, protein, ash and fat in the muscles LD and SM, the averages seing: ashes (0.70% and 1.66%); moisture (75.53% and 75.83%); fat (0.67% and 2.03%); protein (21.63% and 22.49%) for the muscles LD and SM...

Antibodies against Toxoplasma gondii in horses from the coastal and mountain mesoregions of the state of Santa Catarina, Brazil

“…The slaughter of horses as well as the packaging and distribution of horse meat is legal in Brazil, under the proviso that this type of meat be so labeled (JUNQUEIRA et al, 2005). Brazil has become the world's eighth largest horse meat exporter, usually of unwanted horses (CASTAGNO, 2013); the largest importers of Brazilian products are Belgium, Italy, Japan, and France (BRASIL, 2013).…”

Diagnosis and isolation of Toxoplasma gondii in horses from Brazilian slaughterhouses

“…This is because, as in many other countries, horses are viewed as pets. However, Brazil has legal provisions allowing the slaughter of horses, as well as the packaging and distribution of horse meat, including a requirement that products containing horse meat be so labelled (JUNQUEIRA et al, 2005).…”

“…Horse meat is obtained from horses that can no longer work or breed and is produced exclusively for export, because the Brazilian market for horse meat is virtually nonexistent (TORRES;JARDIM, 1987;JUNQUEIRA et al, 2005).…”

Serological Evidence of Hepatitis E Virus Infection in Brazilian Equines

“…The equids sent to slaughterhouses are, usually, those not considered appropriate for their primary purposes and are old animals or animals presenting health issues. They no longer promptly receive veterinary assistance nor have tracking records, which does not favor their sanitary conditions nor animal welfare [44,45]. These are issues that have already raised the concern of the risks of infection with other etiological agents transmitted via the consumption of raw or undercooked equid meat, such as Toxoplasma gondii [28,44,45].…”
