    Abstract: The objective of this study was to evaluate the effects of dietary supplementation of peanut skins (PS) with and without polyphenols on the performance, rumen fermentation, and carcass characteristics of Florida-Native Sheep. Thirty-three intact lambs were randomly blocked by body weight (BW) (33.5 ± 0.1 kg; 11 lambs per treatment) and distributed in three isonitrogenous (17.1%) and isocaloric (2.5 Mcal/kg) diets: 1) Control diet, 2) Diet + 20% of intact peanut skins (IPS) and, 3) Diet + 20% of treated PS without polyphenols (TPS) for 42 d + 7 days of adaptation. Then, lambs were slaughtered to evaluate carcass characteristics and rumen fermentation. Dry matter intake (DMI), BW, and blood samples were collected and analyzed using the effects of treatment, week, interactions, and the random effect of animals. Dietary IPS and TPS did not (P & gt; 0.05) affect DMI (1.14, 1.15 vs 1.04 kg/d) and final BW (35.9, 35.8 vs 36.8 kg) compared to the control. Dietary TPS reduced (P & lt; 0.01) blood glucose levels compared to IPS and control (67.9 vs 74.6, 75.7 mg/dL) but IPS had lower (P = 0.03) blood urea nitrogen than TPS and control (5.79 vs 6.0, 6.32 mmol/L). Both IPS and TPS decreased (P & lt; 0.01) total volatile fatty acid concentration (37.9, 14.2 vs 45.8 mmol/L) and increased rumen pH (7.1, 6.9 vs 6.7) compared to the control. Carcass weight was similar between treatments, TPS reduced (P = 0.01) dressing percentage compared to IPS and control (42.6 vs 45.2, 46.6%), both IPS and TPS reduced liver weight compared to control (230, 223 vs 302 g). Conversely, IPS and TPS increased (P & lt; 0.01) alpha-tocopherol concentration (3.73, 4.0 vs 1.24 mg/g) in lean meat compared to control. This study showed that IPS increased the incorporation of antioxidants in meat without affecting animal performance.

    Effect of ‘Serala’ Sericea Lespedeza ( Lespedeza Cuneata ) Hay on Gastrointestinal Parasite Fecal Egg and Oocysts Counts and Packed Cell Volume in Goats
    Oxford University Press (OUP) ; 2021

    Abstract: Fifty-two naturally parasite-infected intact male Spanish goats 6–7 mo of age were used in a 6-wk trial to investigate effects of ‘Serala’ (SER) sericea lespedeza (SL; Lespedeza cuneata) on indicators of gastrointestinal parasitism. Goats were individually housed in 1.5 x 1.5 m pens. Treatments were pure SER (n = 18) or ‘AU-Grazer’ (AUG; n = 16) varieties of SL or bermudagrass hay (n = 18; CON) at 75% of the ration. A corn-soybean meal-based supplement (25% of the ration) ensured isonitrogenous (17% crude protein), isocaloric diets. Diets were fed to 10% orts. Treatments were assigned for similar initial group mean fecal egg count (FEC). At the start of the study (D 0) and weekly thereafter, FEC and coccidia oocyst counts (FOC) were conducted via a modified McMaster’s technique [eggs per gram (epg); oocysts per gram (opg)], and percentage packed red blood cell volume (PCV) was measured via microhematocrit centrifugation. Data were analyzed using a mixed model for repeated measures. There was a treatment by time interaction (P & lt; 0.001) for FEC. In week 1, SER and AUG were lower (P & lt; 0.02) than CON and were higher than control at week 6 (AUG tendency only, P & lt; 0.10; SER, P & lt; 0.02). The FOC were impacted by treatment (P & lt; 0.008), averaging 1977 ± 945 opg for AUG (lowest, P & lt; 0.01), 3558 ± 876 opg for SER and 4164 ± 955 opg for CON (SER and CON similar). Percentage PCV tended (P & lt; 0.09) to be influenced by a treatment by time interaction in which AUG and SER were similar over time, while PCV for CON animals was lower (P & lt; 0.03) than D 0 at all sampling points after the first week. Overall, there was no effect of SER on FEC or FOC and no effect of AUG on FEC, though PCV was maintained throughout the study for both SL treatments.
