  • Objective: To evaluate the effect of two concentrates and corn stover in the productive performance and economic impact of finishing hair lambs in pens.

    Design/Methodology/Approach: Twenty hair lambs (DorperKatahdin) with an initial live weight of 33.32.9 kg were grouped into ten blocks (two lambs per block) and then were randomly assigned to two treatments: T1) commercial concentrate corn stover and T2) experimental concentrate corn stover (with an 80:20 ratio). The total weight gain (TWG), average daily gain (ADG), dry matter intake (DMI), feed conversion (FC), feeding costs, gross value of TWG, gross profit margin and economics of feed efficiency (EE) were evaluated. An analysis of variance was performed under a completely randomized block design. The means were compared with the Tukey test (0.05).

    Results: There were no differences in TWG, ADG, FC, and DMI (P0.05). T1 has higher costs (US$41.91) per ton of feed. Production costs of diets and feeding were lower for T2, which also showed the best economic feed efficiency (EE26.6%).

    Study Limitations/Implications: Their availability throughout the year is the advantage of using agro-industrial and agricultural by-products (e.g., corn stover) in total mixed diets to finish ovines.

    Findings/Conclusions: Lambs finishing is profitable when the producer formulates and prepares his own diet, reducing feeding production costs without affecting productive variables.
