Effect of Macleaya cordata and Magnolia officinalis plant extracts on oxidative stress control in lambs fed a high-concentrate diet.

Objective: The objective of this experiment was to compare conventional antioxidants and plant extracts for oxidative stress control in lambs fed a high-concentrate diet.

Methods: Forty-eight male Dorper×Santa Ines lambs with an initial weight of 20±1.49 kg and 60 days of age, were used to evaluate the effects of feeding a combination of Macleaya cordata and Magnolia officinalis plant extracts (0 vs 320 mg/kg dry matter [DM]) in combination with selenium+vitamin E (0 vs 100 IU/kg DM of vitamin E and 0.

Implications of low fiber levels in finishing lambs on performance, health, rumen, and carcass parameters.

The objective of this study was to evaluate the effects of different levels of NDF in high-concentrate diets on performance and aspects ruminal, blood, and carcass parameters of finishing lambs. Twenty-four lambs, with initial BW of 24 ± 3 kg, were randomly divided into individual pens, in a completely randomized design, comprising three treatments with eight repetitions each. The treatments consisted of dietary levels of 15%, 20%, and 25% of NDF, based on DM.
