“…This finding could be explained by the adoption of mineral and concentrate supplementation at management A, which increased the weight gain of the animals by 72.5% when compared with management B. The use of diets containing concentrate is used in some cases to accelerate weight gain, improve feed efficiency and consequently reduce the time needed for finishing and yielding greater uniformity in the final product, which adds value and increases producer profits (Cirne et al, 2013). However, the opposite trend was observed for parameter K, which can be explained by the animals with greater precocity not being more likely to achieve a higher weight at maturity than those with slow growth.…”

The aim of this study was to evaluate carcass traits and growth curves in Santa Inês sheep. We used weight data collected from 51 developing sheep from birth to 336 days of age, from March 2012 to May 2013. The sheep belonged to the Core Conservation Team of the Federal University of Piauí and were located at two properties, one in Bom Jesus -PI and one in Cristino Castro -PI. The model used to represent the growth curve was the Gompertz model, in which the model parameters were estimated by using a Gauss-Newton algorithm modified by the NLIN procedure in SAS. The rib eye area (REA) and subcutaneous backfat thickness (SBT) of lambs were evaluated by ultrasound. These results were used to study the growth curve and the relationship between the estimated model growth curve parameters and the evaluated carcass traits. The estimated correlation between A and K was negative. The correlations between the carcass traits (REA and SBT) and the growth curve parameters (A and K) show that animals with a high adult weight and a high rate of precocity do not always yield good carcasses. Birth weight is a good indicator of animals that can achieve better weights in adulthood. The management effect influenced the growth pattern of Santa Inês sheep, indicating a need to adapt management decisions. These adaptations would mainly relate to fodder storage during periods of food scarcity, which indirectly relates to climate effects, so there would be no influence on animal growth.

“…Portanto, a utilização de dieta com alta proporção de concentrados depende de fatores econômicos e da disponibilidade dos ingredientes em cada região (Paim et al, 2011;Cirne et al, 2013). Esses autores ressaltaram que o consumo é o maior determinante do desempenho animal (Homem Júnior et al, 2010;Nóbrega et al, 2014).…”

“…As dietas para ovinos em confinamento e semiconfinamento, tradicionalmente, são balanceadas com maiores proporções de volumosos, por causa dos altos custos dos grãos e dos concentrados proteicos (Barros et al, 2009;Cirne et al, 2013). Apesar disso, o fornecimento de dietas com elevados teores de concentrado para animais jovens, que apresentam boas respostas a esse tipo de alimentação, tem sido utilizado com o objetivo de intensificar o sistema de produção, pois permite a terminação de animais com acabamento de gordura e peso adequado (Leme et al, 2002).…”

“…Resultado distinto para fêmeas (Tabela 4), que apresentaram menores médias de PAM 10 para ICA. Outros autores observaram níveis de conversão alimentar inferiores ao observados neste estudo, com médias de 3,35 a 3,59 para cordeiros em confinamento tanto para machos como fêmeas (Jacques et al, 2011;Cirne et al, 2013).…”

Economic analysis of feeding lambs confined by partial replacement of the concentrated by air part of cassava

The objective of this study was to evaluate the influence of inclusion of cassava raw in the diet of lambs, partially replacing concentrate food in order to reduce production costs. The experiment was conducted at XXXXXX-XXXXX, in XXXXXXXX-XXX. 28 sheep were used in the Pantaneira race, 14 males and 14 females, mean age of 75 days, average weight 18.84 kg ± 2.02 for 65 days. The experimental design were in randomized blocks in a factorial method (2x2) with two factors, distributed in 7 females and 7 males. Received diets were: treatment 1 - control and treatment 2 - 10% Air Part of Cassava (PAM 10) replacing concentrate, comprising two factors. The economic analysis of animal performance demonstrated the lowest feeding costs, lower interest on working capital and higher net margin for the treatment PAM 10. These results allow us to conclude that inclusion of raw cassava in the diet of lambs in partial replacement of concentrate can result in higher profitability.
