Abstract

NEUMANN, Mikael et al. Effect of utilization of yeast (Saccharomyces cerevisiae) for feeding Ile de France lambs in creep-feeding system. Cienc. Rural [online]. 2008, vol.38, n.8, pp. 2285-2292. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782008000800030.

The experiment was conducted at the Núcleo de Produção Animal of the Universidade Estadual do Centro Oeste do Paraná (UNICENTRO). The trial aimed to evaluate the effect of living yeast (Saccharomyces cerevisiae) on dry matter intake of concentrate and performance of lambs kept in the creep-feeding system, submitted to the following treatments: T1 - 0g animal-1 day-1; T2 - 0.4g animal-1 day-1; e T3 - 0.8g animal-1 day-1. Twenty-seven lambs Ile de France of simple birth with an average age of 40 days and average live weight of 19.5kg were used. The whole supplementation period in creep-feeding was 63 days, divided in three periods of 21 days. No significative interaction was observed between supplementation of level of the yeast and evaluation period for average daily dry matter intake of concentrate, for average daily weight gain and feed conversion of the g of concentrate by 100g weight gain. No difference of supplementation of level of the yeast for average daily dry matter intake of concentrate (635.7g day-1) and average daily weight gain (418g day-1) for Ile de France lambs simple birth on creep-feeding system, according to supplementation of living yeast.

Keywords : intake of concentrate; milk production; weight gain.
