“…Madruga et al (1999a) also stated that the age influences fat content because young animals have less fat in their muscle composition, since the ingested nutrients are converted into structure (bones and tissues). This lipid content concentration can be considered a plus before the search of consumers for foods with low fat.…”

-The objective of this study was to evaluate the centesimal composition and fatty acids in meat from animals fed diets containing levels of soybean hulls. The experiment was conducted at UESB in Itapetinga-BA, Brazil. Twenty-five confined Santa Inês rams were used. Treatments consisted of different levels of substitution of corn by soybean hulls (0, 25, 50, 75 and 100%) and elephant grass silage as forage. The design was completely randomized. Samples of concentrate and silage were collected to evaluate the fatty acid composition. The experimental period lasted 110 days. After this period, the animals were slaughtered and samples of the longissimus muscle were collected and vacuum-packed for further analysis. The levels of total lipid and protein showed quadratic effect with the increase of soybean hulls in the diet, as the moisture increased linearly with inclusion. There was no effect of treatments on the percentage of ash. The composition of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), PUFA/SFA and omega 6 (n-6) did not change, but increases in n-3 and reduction in the n-6:n-3 ratio were observed when the the amount of soybean hulls in the diet increased. The content of fatty acid conjugated linoleic acid (CLA) ranged from 3.0 to 4.0 g/kg at levels of substitution.The inclusion of soybean hulls in the diet increased CLA, the n-3 and decreased the n-6:n-3 ratio.

“…The observed results are similar to those presented by Grande et al (2009) in an extensive review of literature, of 70.80% to 80.25% for moisture, 18.50% and 23.82% for protein and 0.79% to 1.6% for ash. However, for the total lipid content, the literature reports range from 0.5% to 7.2% (Madruga et al 1999;Dhanda et al 2003;Silva, 2005), which may be related to the sex , slaughter weight (Mahgoub et al, 2004), age, food, breed types and the method of lipid extraction.…”

“…Goat meat has important nutritional characteristics, such as protein source of high biological value (Amaral et al, 2007), low cholesterol content (40 mg/100 g) lower than sheep (62 mg/100 g) and bovine meat (70 mg/100g), according to Souza & Visentainer (2006), and it is lower in fat, which results in a reduction proportion of saturated fat and calories when compared to other red meat (Madruga et al, 1999;Malan 2000). Silva Sobrinho & Osório (2008) reported that despite these characteristics of goat meat, the consumption is considered low (about 0.4 kg/capita/year) compared to beef (40 kg/capita/year).…”

-Twenty-seven carcasses of non-castrated confined goat kids, (18 ¾ Boer + ¼ Saanen and nine Saanen) with slaughtered weight of 30.1 ± 0.27 kg were used to evaluate quantitative characteristics of the carcass and qualitative characteristics of the loin and shoulder. The animals were distributed in a completely randomized design in a 2 × 3 factorial arrangement (breed group × diet). The diets consisted of inclusion of dry yeast, as follows: soybean meal, soybean meal + dried yeast or dried yeast. The other ingredients of the diets were oat hay (30% DM), ground corn and mineral mixture. Hot carcass weight, cold carcass weight, weight loss by cooling, true carcass yield and carcass compactness index were not influenced by the inclusion of dry yeast nor by racial group. Saanen goats presented the highest carcass commercial yield of carcass, but they needed 15 days more to reach the slaughter weight. The cut yields were not affected, but a significant interaction for shoulder yield occurred. Dry yeast and breed group did not influence the measurements of the loin, the muscle:bone ratio, the cooking losses, the shear force and composition. There was a significant interaction between the inclusion of dry yeast in the diets and the breed group for the muscle proportion on loin, which was higher in the ¾ Boer + ¼ Saanen group. For the shoulder, inclusion of dry yeast and breed group did not alter the proportions of muscle, fat, protein and ash. However, in Saanen goats, the proportion of bone and moisture content were higher and total lipid content was lower. The ¾ Boer + ¼ Saanen groups showed higher precocity. Dry yeast is an alternative protein source that can be included in diets for goat kids.Key Words: byproduct of sugar cane, genetic group, goat, meat quality, Saccharomyces cerevisiae Características quantitativas de carcaça e de qualidade da carne de cabritos ¾ Boer + ¼ Saanen e Saanen alimentados com rações contendo levedura seca RESUMO -Foram utilizadas 27 carcaças de cabritos machos não-castrados, confinados, sendo 18 ¾ Boer + ¼ Saanen e nove Saanen com peso de abate de 30,1 ± 0,27 kg, para avaliar as características quantitativas da carcaça e qualitativas do lombo e da paleta. Os animais foram distribuídos em delineamento inteiramente casualizado em arranjo fatorial 2 × 3 (grupo racial × rações). As rações foram constituídas pela inclusão de levedura seca, sendo: farelo de soja, farelo de soja + levedura seca ou levedura seca. Os demais ingredientes das rações foram o feno de aveia (30% da MS), milho moído e mistura mineral.Os pesos de carcaça quente e de carcaça fria, as perdas de peso por resfriamento, o rendimento verdadeiro de carcaça e o índice de compacidade de carcaça não foram influenciados pela inclusão da levedura seca nem pelo grupo racial. O grupo Saanen apresentou maior rendimento comercial de carcaça, porém 15 dias a mais de idade para atingir o peso de abate. Os rendimentos de cortes não foram influenciados, porém ocorreu interação significativa para rendimento de paleta. A levedura sec...

“…Os produtores buscam sua sobrevivência, na maioria dos casos, através da exploração animal, destacando-se na criação de caprinos (Madruga et al 1999). O rebanho caprino paraibano ocupa o quinto lugar do rebanho nacional, possuindo um efetivo de 653.730 mil cabeças, sendo que as regiões do Cariri Oriental e Ocidental são as mais importantes para a caprinocultura, possuindo um efetivo correspondente a 52,6% do rebanho estadual e destacando-se, principalmente, na exploração leiteira (Rodrigues 2003, IBGE 2006.…”

526Pesq. Vet. Bras. 29(7): 526-532, julho 2009 RESUMO.-A tuberculose é uma enfermidade infecciosa, de distribuição mundial, provocada por micobactérias patogênicas, que afeta o homem e diversas espécies de mamíferos. Visando determinar a prevalência da Tuberculose Caprina e identificar fatores de risco associados à infecção foram tuberculinizados, através do Teste Tuberculínico Comparado (TCC), 1.866 caprinos de diferentes raças e idades, oriundas de 84 propriedades localizadas na microrregião de Monteiro, Estado da Paraíba, Brasil. A interpretação do TCC foi aferida pelo cálculo da diferença obtida entre as cutimetrias correspondentes às respectivas tuberculinas, antes e 72 horas após a inoculação: negativa, quando PPD bovina for menor que a aviária ou maior em até 1,8mm; suspeita ou inconclusiva, reação à PPD bovina maior que a aviária entre 1,9 e 2,4mm; positiva, reação à PPD bovina maior ou igual a aviária em 2,5mm. Das cabras submetidas ao TCC, 0,47% (9/1866), reagiram positivamente (IC 95% = 0,23-0,94% Tuberculosis is an infectious disease of world wide distribution caused by pathogenic mycobacteria that affect humans and several mammals species. In order to determine the prevalence of tuberculosis in goats and to identify risk factors associated with infection, 1,866 goats of different breeds and ages from 84 herds in the microregion of Monteiro, State of Paraíba, Northeast Brazil, were tuberculinized by the Comparative Cervical Test (CCT). Interpretation of the CCT was checked by calculation of the difference obtained between skin measures correspondent to respective tuberculins, before and 72 hours after inoculation: negative, when bovine PPD is smaller than avian PPD or larger in up to 1.8mm; suspicious or inconclusive, reaction to bovine PPD larger than avian PPD between 1.9 and 2.4mm; positive, reaction to bovine PPD larger than or equal to avian PPD in 2.5mm. From goats submitted to CCT, 0.47% (9/1866) reacted positively (95% CI = 0.23%-0.94%). The prevalence of positive herds to caprine tuberculosis was 10.71% (95% CI = 5.02-19.37%). When submitted to necropsy and histopathologic examination, a positive goat at tuberculin test presented tuberculosis-like lesions. The presence of Acid-Alcohol Resistant Bacilli (BAAR) was also detected by direct bacterioscopy; in relation to herd size, herds with larger number of animals (>25) with high incidence of the disease, and presence of the infection was evidenced in properties that raised cattle in association with goats and did not carry out tuberculin tests in cattle.INDEX TERMS: Caprine tuberculosis, prevalence, tuberculin test.
