The use of guava byproduct in the production of feedlot sheep in Brazil: impacts on the productive and economic performance
ABSTRACT This study evaluated the effects of replacing ground corn with dehydrated guava (Psidium guajava L.) byproduct, at concentrations of 0.0, 8.2, 16.4, and 24.6% on the intake and digestibility of nutrients as well as on productive and economic performance of lambs. The study included 40 uncas...

| description | ABSTRACT This study evaluated the effects of replacing ground corn with dehydrated guava (Psidium guajava L.) byproduct, at concentrations of 0.0, 8.2, 16.4, and 24.6% on the intake and digestibility of nutrients as well as on productive and economic performance of lambs. The study included 40 uncastrated feedlot Santa Inês sheep with an average age of 120 days and an average initial weight of 17.4±1.27 kg, distributed in individual stalls in a completely randomized design with four treatments and 10 replicates. Santa Inês sheep fed diets containing higher levels (16.4%) of guava byproduct showed lower weight gain and feed conversion and reached slaughter weight later. Replacing corn with guava byproduct at higher levels increased acid detergent fiber and reduced non-fiber carbohydrate intake and nutrient digestibility. The inclusion of up to 16.4% of guava byproduct in the diet of feedlot sheep is appropriate for maintaining good performance and economic viability of the system. |
