This study evaluated enteric methane (CH₄) emissions, dry matter intake (DMI), and performance in rearing beef heifers fed either a guinea grass-only diet (0WCS) or grass supplemented with whole cottonseed (WCS) at 0.5% of body weight (BW). Twenty-four Braford were randomly allocated into four pens (three animals per pen) treatment over two experimental periods. Methane emissions measured using the SF₆ tracer technique. Heifers receiving WCS supplementation produced 29% less CH₄ (120.64 vs....

The aim of this study was to evaluate the effect dietary incorporation tannin-rich woody species on meat oxidative stability, carcass traits and quality in goats. Two were tested using a three-treatments feeding trial, where treatments consisted of: Larrea divaricata Acacia aroma both at 12.5% dry matter basis diet control (alfalfa hay). All diets iso-protein iso-energy. Carcass conformation, compactness, fatness subcutaneous fat deposition evaluated. Intake, liveweigh, Longissimus thoracis...
A total of 288 piglets weaned at 28 d and weighing 7.6 ± 0.2 kg were used in a 35-d experiment to evaluate the effect CP content (44% vs. 49% CP) soybean meal (SBM), micronization (fine grinding) SBM (HP-SBM), soy protein concentrate (SPC; 65% on tract apparent digestibility (TTAD) growth performance. In phase I (d 0 21 experiment), there was positive control diet that included 6.5% from SPC with negative supplied same amount as regular (R-SBM) 44% CP. The other 4 diets dietary 2 different...
An experiment was conducted to assess the impact of increasing levels supplemental soybean meal (SBM; 45.7% CP) in cattle consuming tropical grass hay (Panicum maximum cultivar Gatton; 7.0% CP and 81.8% NDF) drinking low salt water (LS) or high (HS). Six ruminally fistulated beef steers (BW = 375 ± 43 kg) were used a 6-treatment, 4-period crossover experiment. Treatments arranged as 2 × 3 factorial, with (LS HS: 786 6,473 mg/kg total dissolved solids [TDS], respectively) SBM (0, 0.2, 0.4%...
Twenty Hampshire lambs (31 ± 4 kg BW) in individual metabolism cages were used a 10-treatment by 2-period ( = 4) trial to evaluate the interaction between protein supplementation and sulfate water on intake metabolic responses when fed low-quality grass hay (; 6.4% CP, 79.5% NDF). The treatment structure was 2 × 5 factorial: qualities (WQ; low-sulfate [LS] high-sulfate [HS]; 442 8,358 mg/kg total dissolved solids, respectively) soybean meal levels (SBM; 0%, 0.25%, 0.50%, 0.75%, 1.00% BW/d)....
Se evaluaron parámetros de desempeño productivo y calidad la res carne 18 novillos raza Criollo Argentino (CrA), Braford (Bra) cruza F1 CrA x Bra (F1). Los animales fueron sometidos a un engorde corral durante 70 días sacrificados una edad promedio 19,3 meses. lograron mayor engrasamiento subcutáneo que (8.05 vs 5.30 mm, P = 0.0008), aunque no se hallaron diferencias 1 en el peso vivo definitivo (418 kg, 0.819), ni ganancia diaria (1.39 kg d , 0.8196) sobre nivel grasa intramuscular (1.78...
The objective of this experiment was to study the effect DDGS supplementation on feed intake and ruminal fermentation profile by steers (Braford crossbred; 383 ± 100 kg BW) fed low-quality grass hay. Treatments consisted hay (Megathyrsus maximus cv. Gatton panic) supplemented with three levels DDGS: 0 (no supplementation; 0DDGS), 6 (6DDGS) 12 (12DDGS) g (DM basis) /kg BW respectively. Total OM increased linearly (P < 0.01) while forage decreased increasing DDGS. A linear decrease observed in...
The aim of this study was to access the effect protein supplementation on intake, digestion, and N utilization in lambs fed a low-quality hay (Panicum maximum; 6.4% CP, 79.5% NDF, 54.3% ADF) drinking high-salt water. Twenty Hampshire (n = 4; 31 ± 4 kg BW) allocated individual cages ten treatments by two period (10 × 2) trial. Treatments consisted (2 5 factorial) water qualities (WQ; low salt, LS; 442 mg/L total dissolved solids (TDS) 108 sulfate; high HS; 8358 TDS 6363 sulfate) five soybean...
The objective of this study was to assess the effect two inclusion rates Fermenten (FER, Church & Dwight Co., Inc., Princeton, NJ) on ruminal fermentation profile, blood urea nitrogen (BUN) and apparent total tract digestibility nutrients in Angus crossbred steers. Eight steers, fitted with cannulas, were randomly assigned treatments a switchback design. Steers fed basal diet (92% DM) comprised mainly corn gluten feed, soybean hulls, peanut different top-dressed premixes (8% achieve: 1)...
