“…However, the demand for lamb meat can be considered low when compared with other meats such as beef, pork, and poultry (HERMUCHE et al, 2013a(HERMUCHE et al, , 2013b. Some factors exert a great influence on lamb meat consumption, mainly those associated with eating habits and purchasing power (PAIM et al, 2011). Also according to these authors, the decisive factor for the expansion and consolidation of this market in Brazil is quality carcass production.…”

This study aimed to evaluate the effect of pre-and post-calving feed restriction on quantitative characteristics and lipid profile of meat from Morada Nova sheep. Twenty-four male lambs from single births only, with an initial weight of 10.0 ± 3.07 kg and at four months of age, were distributed in a randomized complete design, into three groups: pre-calving restriction (R-PRE; n=8) post-calving restriction (R-POS; n=8), and ad libitum feeding (ADLI; n=8). To make up the experimental treatments, the feeding regime applied previously on the sheep in the last third of pregnancy was considered. Treatments ADLI and R-POS were composed of lambs born from ewes fed ad libitum in the last third of pregnancy. Treatment R-PRE consisted of lambs born from ewes subjected to feed restriction in the last third of pregnancy at 60% of the recommended requirements for the group of ewes feeding ad libitum. For the lambs from treatments ADLI and R-PRE, the diet was supplied allowing 20% of the total supplied as refusals. For the animals from R-POS, a 30% restriction was imposed in relation to the animals feeding ad libitum. Animals were slaughtered with an average live weight of 25 kg. Afterwards, carcasses were chilled at 4 ºC for 24 h. Meat quality measurements were taken on the right side of each carcass; pH was determined immediately after slaughter and then again after chilling. Samples of the longissimus dorsi muscle were collected and frozen at -20 ºC. Moisture, ash, protein, total lipids, water-holding capacity, and cooking loss were determined in the meat samples, which were then subjected to the shear-force test. The sensory analysis was determined by the hedonic-scale test, in which sensory parameters of tenderness, juiciness, flavor, aroma, and overall acceptability and fatty acid profile were evaluated. There was a feed-restriction effect on protein, lipids, and water-holding capacity (P<0.05). Meat sensory attributes were not influenced by the nutritional regimes (P>0.05). Saturated fatty acid contents were affected by the treatments (P<0.05); however, there was no effect of nutritional regimes on mono-or polyunsaturated fatty acids (P>0.05). Feed restriction does not compromise the physicochemical or sensory quality of Morada Nova lambs meat, but rather provides a meat product of good acceptance. ResumoObjetivou-se avaliar o efeito da restrição alimentar pré e pós-natal sobre características qualitativas e do perfil lipídico da carne de ovinos da raça Morada Nova. Vinte e quatro cordeiros foram usados, machos, somente de parto simples, peso inicial 10,0 ± 3,07 kg e quatro meses de idade, distribuídos num delineamento inteiramente casualizado, em três grupos: restrição pré-natal (R-PRE; n=8) e pós-natal (R-POS; n=8), e ad libitum (ADLI; n=8). Para composição dos tratamentos experimentais foi considerado o manejo alimentar aplicado anteriormente nas ovelhas no terço final de gestação. Os tratamentos ADLI e R-POS foram formados por cordeiros nascidos de ovelhas alimentadas ad libitum no terço final da gestação....

“…Centro de custo de produção para ovinos consumindo dietas contendo substituição parcial do concentrado por parte aérea de mandioca em sistemas confinados e semiconfinados, durante 65 dias O custo operacional total dos cordeiros machos em confinamento foi de R$3,07kg -1 (Tab. 6), valor inferior ao encontrado por outros autores: R$3,57kg -1 de peso vivo (Paim et al, 2011). Para os cordeiros machos de semiconfinamento, observou-se valor de R$2,33kg -1 de peso vivo (Tab.…”

“…A receita total teve uma diferença significativa (P<0,05) para os sistemas de produção conforme o peso final dos cordeiros, pelo fato de o pagamento ser feito pelo peso vivo, ou seja, animais com maior peso representam maior receita (Paim et al, 2011). O mesmo fato foi observado com a margem líquida, que apresentou diferença significativa (P<0,05) para efeito de sexo, em que foi verificado que os machos com valor de R$112,99 foram superiores às fêmeas em R$21,70 (Tab.…”

“…Fixed costs (depreciation, interest on average capital invested at the rate of 6% per year, and maintenance and preservation at the rate of 2% on the average capital invested) and variable costs (feeding, medication and health, energy and fuel, purchase of animals, and labor) were considered. The effective operating cost, the total operating cost (TOC), the total cost, and the gross revenue (GR) composed the basis for the economic analysis (PAIM et al, 2011). The economic analysis was based on the calculation of the gross margin, which consists of the difference between gross revenue (GR) and the effective operating cost and on the obtention of the net margin (NM): NM = GR -TOC (SANTOS et al, 1997).…”

This study aimed to evaluate the production performance, quantitative carcass characteristics, and economic viability of lambs of genetic group Pantaneiro finished under four production systems: 1) Stockpiled Brachiaria brizantha cv piatã pasture; 2) Consortium of sorghum intercropped with Brachiaria brizantha cv piatã; 3) Feedlot based on sorghum silage and 2% body weight energyprotein supplementation, 4) Feedlot based on sorghum silage and 4% body weight energy-protein supplementation. Were used one hundred Pantaneiro lambs with an average body weight of 17.85 ± 2.50 kg and at 70 ± 15 days of age, approximately. The average final body weight and total body weight gain of the animals finished on the consortium of sorghum intercropped with Brachiaria brizantha cv piatã were higher than those obtained with feedlot based on sorghum silage and 2% body weight energy-protein supplementation. However, when this system were compared with sorghum silage and 4% body weight energy-protein supplementation, these characteristics did not differ (P > 0.05). Hot and cold carcass weights were lower when animals were fed sorghum silage and 2% body weight energyprotein supplementation as compared with the animals finished on the other systems. The greatest hot (48.20%) and cold (45.83%) carcass yields were observed in animals finished on sorghum silage and 4% body weight energy-protein supplementation. For the carcass compactness index, animals that received sorghum silage and 4% body weight energy-protein supplementation obtained higher values than those observed for 2% of supplementation. The economic evaluation showed a great return for the finishing systems, except for sorghum silage and 4% body weight energy-protein supplementation, and concluded that finishing lambs in a crop-livestock integration system presented a higher benefit/ cost ratio (1.61). Therefore, based on the conditions under which this study was conducted, the croplivestock integration is the most viable system for finishing lambs. ResumoAvaliou-se o desempenho produtivo, características quantitativas das carcaças e viabilidade econômica de cordeiros do grupamento genético Pantaneiro, terminados em quatro sistemas de produção: 1) Pastagem vedada de Brachiaria brizantha cv piatã; 2) Pastagem de Brachiaria brizantha cv piatã em plantio consorciado com sorgo; 3) Confinamento a base de silagem de sorgo e suplementação energético-proteica fornecida na proporção de 2% do peso corporal; 4) Confinamento a base de silagem de sorgo e suplementação energético-proteica fornecida na proporção de 4% do peso corporal. Foram utilizados cem cordeiros Pantaneiros com peso médio de 17,85 ± 2,50 kg e 70 ± 15 dias de idade, aproximadamente. O peso corporal médio final e o ganho de peso corporal total dos animais terminados em consórcio de sorgo com Brachiaria brizantha cv piatã foram superiores aos obtidos com o confinamento a base de silagem de sorgo e suplementação energético-proteica na razão de 2% do peso corporal. No entanto, quando comparados com o confinamento a ...
