“…This effect was not observed in the lambs of the present study probably due to the higher slaughter weight and age of the lambs. Our lambs were 60 days old when sheep's milk production may be declining (Hentz et al, 2012). We must also take into account that the lambs in sucking system were milk-fed but with free access to the pasture as well.…”

This study aims to evaluate the physicochemical characteristics, fat composition, and sensory attributes of lamb meat produced in two feeding systems: (1) Unweaned and unsupplemented lambs in the pasture and (2) early weaned lambs in the pasture with concentrate supplementation post-weaning. The experiment was performed in the winter–spring pastures in the subtropical region of Brazil. The experimental design was completely randomized with two treatments (feeding systems), four paddocks per treatment and twenty lambs (experimental units) per paddock. Carcass weight, dressing percentage, pH, rib eye area, subcutaneous fat thickness, and visual fatness were determined. Loin samples were used for instrumental color, thawing and cooking loss, shear force, water holding capacity, fat and sensory analyses. Carcass pH did not differ between the systems (p > 0.05). Supplemented weaned lambs showed a higher body condition score, carcass weight, dressing percentage and fatness (p < 0.001). They also showed higher (p < 0.05) total fat and long chain fatty acid (FA) content than unweaned lambs. Lamb meat from both systems showed similar and high sensory acceptance. Early weaning and supplementation proved to be a better choice for producing lambs in the winter–spring pasture, under subtropical conditions, because it promoted better carcass and meat traits and good sensory attributes, which could improve payment to the farmers.

“…However, expenditures with concentrate may increase production costs and reduce profitability. On the other hand, studies of creep grazing strategy in Brazil are scarce (HENTZ et al, 2012;PIAZETTA et al, 2009;RIBEIRO et al, 2013;SILVA et al, 2012;STIVARI et al, 2011) and their economic feasibility have not been widely studied (STIVARI et al, 2013). Silva (2010) reported no difference regarding the average daily gain when comparing both supplementation systems.…”

Due to the high value of land in Brazil, it is necessary to conduct studies about the economic feasibility of the choice of production strategy. The soil expectation value determines the maximum purchase price of the bare land, considering the horizon of infinite time. Therefore, this methodology was used to assess the financial-economic feasibility of sheep production systems in pasture with either creep feeding or creep grazing termination of unweaned lambs. Six scenarios were proposed to evaluate the economic feasibility, according to the finishing strategy, the dry matter (DM) offer per kg of body weight (BW) per day (12% or 8%) and the corresponding percentage of white clover supplementary pasture area (30% to 50% -relative to the main pasture area). The soil expectation value was positive in all of the evaluated systems Creep grazing finishing system with 8% DM offer per kg BW and with 30% of reduction on the white glover area resulted in the largest financial return (R$ 289,043.71) and the highest internal return rate (1.74%). The most economically attractive scenario, however, was the creep feeding finishing system with 8% DM offer per kg of BW, which allowed expenses with the land as high as R$ 22,950.68 per hectare. Adjustments in the main pasture offer, which do not compromise animal performance, can enable economic improvement on the feasibility of grazing sheep production systems. The soil expectation value can be used as an economic indicator in the choice of location or expansion of grazing sheep farms.Keywords: Animal production. Creep feeding. Creep grazing. Land cost. Production strategy. ResumoDevido ao valor elevado da terra no Brasil, é necessária a realização de estudos de viabilidade econômica durante a escolha da estratégia de produção. O valor esperado da terra determina o preço máximo de compra da terra nua, considerando o horizonte de tempo infinito. Portanto, essa metodologia foi utilizada para avaliar a viabilidade econô-mico-financeira de sistemas de produção de ovinos em pastagem com terminação em creep feeding ou creep grazing de cordeiros não desmamados. Seis cenários foram propostos para avaliar a viabilidade econômica de acordo com a estratégia de terminação, a oferta de matéria seca (MS) por kg de peso vivo (PV) por dia (12% ou 8%) e a área de pastagem suplementar correspondente de trevo branco (30% a 50% -em relação à área de pastagem principal). O valor esperado da terra foi positivo em todos os sistemas avaliados. O sistema com terminação em creep grazing com 8% de oferta de MS/PV e com redução da área suplementar para 30% apresentou o maior retorno financeiro (R$ 289.043,71) e a maior taxa interna de retorno (1,74%). No entanto, o cenário economicamente mais atraente foi o sistema de creep feeding com 8% de oferta de MS/PV, permitindo despesas de até R$ 22.950,68 por hectare. Ajustes na oferta da pastagem principal, que não comprometam o desempenho do animal, podem permitir melhores resultados econômicos de sistemas de produção de ovinos em pastagem. O valor espera...
