Abstract Eighteen Katahdin (initial body weight of 74 kg; SEM=1.8) and 18 St. Croix ewes (55 kg; SEM=1.3) were used in an experiment with four 6-wk periods to determine effects of dietary level of Sericea lespedeza (Lespedeza cuneata) containing 5.8% condensed tannins (dry matter; DM) and other supplemental ingredients on feed intake, digestion, and ruminal methane emission. Diets were consumed ad libitum and included a concentrate supplement at 0.45% BW (DM). Alfalfa was the basal forage for control (CON), ionophore (ION; lasalocid at 33 mg/kg DM), coconut oil (3%; CCO), and soybean oil (3%; SBO) diets, and forage in moderate- and high-lespedeza diets was a 1:1 mixture of alfalfa and lespedeza and all lespedeza, respectively (MSL and HSL, respectively). Data were analyzed with a 2 x 6 factorial arrangement of treatments, period as a repeated measure, and a mixed effects model. Digestion and methane emission were determined in weeks 4, 10, 16, and 22. Total DM intake was similar among treatments (P = 0.070) but numerically greatest for HSL (1,197, 1,297, 1,491, 1,203, 1,195, and 1,207 g/d; SEM=81.1), OM digestibility ranked (P < 0.05) CON, ION, CCO, and SBO > MSL > HSL (69.2, 57.6, 50.3, 66.3, 66.0, and 68.7%; SEM=1.57), and digestible OM intake was similar among treatments (P = 0.517; 697, 607, 589, 598, 635, and 690 g/d for CON, MSL, HSL, ION, CCO, and SBO, respectively; SEM=50.4). There were no interactions involving time in ruminal methane emission, which was greatest among treatments for CON (P < 0.05) in MJ/d (1.39, 0.93, 0.90, 0.92, 0.85, and 0.96; SEM=0.069) and relative to digestible energy intake (20.6, 15.7, 16.8, 16.1, 13.7, and 13.9% for CON, MSL, HSL, ION, CCO, and SBO, respectively; SEM=1.223). In conclusion, dietary inclusion of Sericea lespedeza may offer a natural and sustainable means of decreasing ruminal methane emission by hair sheep as previously shown in goats, with a magnitude of impact similar to that of some other supplemental dietary ingredients.

Abstract Twenty-four Alpine doelings (initial body weight (BW) and age of 25.3±0.55 kg and 10.4±0.11 mo, respectively) and 24 Katahdin ewe lambs (28.3±1.02 kg and 9.6±0.04 mo, respectively) were used to determine effects of dietary level of Sericea lespedeza (Lespedeza cuneata; 10% condensed tannins) on heat energy and ruminal emission of the greenhouse gas methane determined with an open-circuit calorimetry system. Pens with Calan feeding gates were used in the study with four 6–7-wk periods. Diets (i.e., treatments) consumed ad libitum were 75% ground hay, alfalfa, a 1:1 mixture of alfalfa and lespedeza (AL), and lespedeza. Data were analyzed with a 2 x 3 factorial arrangement of treatments, repeated measure of period, and a mixed effects model. Feeders were open 195 and 205 min/d for Alpine and Katahdin (SEM=9.8) and longer (P < 0.05) for diets with lespedeza (159, 209, and 231 min/d for alfalfa, AL, and lespedeza, respectively). Rate of dry matter intake (DMI) was greater (P < 0.05) for Katahdin vs. Alpine (10.2 and 6.1 g/min) and for alfalfa than for AL and lespedeza (11.1, 8.1, and 6.7 g/min, respectively). Heat energy was greater (P < 0.05) in MJ/d for Katahdin than for Alpine (10.19 vs. 7.90) and similar among diets (9.20, 9.40, and 8.53; SEM=0.266), but values in kJ/kg BW0.75 were similar between animal types (560 and 579; SEM=8.4) and greatest (P < 0.05) among diets for AL (563, 592, and 553 for alfalfa, AL, and lespedeza, respectively). Ruminal methane emission differed (P < 0.05) between animal types in MJ/d (1.17 and 1.44), kJ/g DMI (1.39 and 1.23), and kJ/g average daily gain (ADG; 18.1 and 9.8 for Alpine and Katahdin, respectively). Regardless of period, diet did not impact methane emission in MJ/d or relative to DMI, BW, or ADG. In conclusion, it is unclear why dietary inclusion of lespedeza did not reduce ruminal methane emission as in previous studies. Species differences in methane relative to DMI and ADG (i.e., lower for sheep than for goats) deserve further attention.

Enteric Methane

A quarter of all anthropogenic methane emissions in the United States are from enteric fermentation, primarily from ruminant livestock. This study was undertaken to test the effect of a methane inhibitor, 3-nitrooxypropanol (3NOP), on enteric methane emission in lactating Holstein cows. An experiment was conducted using 48 cows in a randomized block design with a 2-wk covariate period and a 12-wk data collection period. Feed intake, milk production, and fiber digestibility were not affected by the inhibitor. Milk protein and lactose yields were increased by 3NOP. Rumen methane emission was linearly decreased by 3NOP, averaging about 30% lower than the control. Methane emission per unit of feed dry matter intake or per unit of energy-corrected milk were also about 30% less for the 3NOP-treated cows. On average, the body weight gain of 3NOP-treated cows was 80% greater than control cows during the 12-wk experiment. The experiment demonstrated that the methane inhibitor 3NOP, applied at 40 to 80 mg/kg feed dry matter, decreased methane emissions from high-producing dairy cows by 30% and increased body weight gain without negatively affecting feed intake or milk production and composition. The inhibitory effect persisted over 12 wk of treatment, thus offering an effective methane mitigation practice for the livestock industries.

Tannins have become important phytochemicals in ruminant production, due to their wide range of biological activities. The use of a crude extract often comes with limitations, such as reduced feed intake and fibre digestibility, which could be overcome by the use of encapsulated tannin extract. In this study, four rumen-cannulated Merino wethers were used in a 4 × 4 Latin square design to determine the effect of encapsulating Acacia mearnsii tannin extract on intake, nutrient digestibility, and methane emission. The animals were placed on one of the following diets: control diet only, diet + silvafeed (Silvafeed ByPro, 10 g/kg feed), diet + Acacia tannin extract (ATE), 40 g/kg feed), and, diet + lipid-encapsulated-ATE (palm oil encapsulated ATE, 50 g/kg feed) in 4 cycles. Wethers were offered an Eragrotis and Lucerne hay-based total mixed ration diet above maintenance requirement with forage: concentrate ratio 50:50. Silvafeed, a commercial tannin additive, was used as a positive control. Nutrient intake was not different across the treatments, but nutrient digestibility was affected by dietary additives (p < 0.05). Compared to the control, and unlike the crude extract, encapsulated-ATE and silvafeed did not reduce dry matter, organic matter, and neutral detergent fibre digestibility. While the overall N-retention and total N-excretion (g/d) were not affected by dietary additives, ATE and encapsulated-ATE diets reduced urine-N excretion (g/d) and only a slight reduction was observed in silvafeed diet. The faecal-N proportion was highest in the ATE diet (388 g/kg N-intake), followed by encapsulated-ATE (317 g/kg), and silvafeed (267 g/kg), with the control diet having the lowest proportion (230 g/kg). The acetate:propionate (A:P) ratio reduced as a result of the inclusion of dietary additives with crude ATE and silvafeed having lower A:P ratio compared to the control diet. Methane production expressed in g/kg dry matter (DM) intake was reduced by 12%, 30% and 19% in the silvafeed, crude ATE and encapsulated-ATE diets, respectively (p < 0.05). The reduced methane production with higher neutral detergent fibre (NDF) digestibility in the encapsulated-ATE, compared to the crude-ATE, confirms that encapsulated-tannin can be used as an additive in ruminant diets.

A normal and a low-tannin sericea lespedeza (Lespedeza cuneata (Dumont) G. Don.) cultivar were grown in controlled environments under a warm (32/24 °C) or cool (22/17 °C) temperature regime. Both cultivars accumulated more dry matter at the higher temperature. The normal-tannin sericea contained a higher concentration of tannin, and lower concentrations of crude protein and neutral detergent fiber (NDF than the low-tannin sericea. Tannin concentration in the leaves of the normal-tannin cultivar was 10 percentage units greater and crude protein and NDF were each 3 units lower at 32/24 °C than at 22/17 °C. Tannin concentration in the leaves of the low-tannin cultivar was 2 percentage units higher, crude protein was 3 units lower, and NDF was 3 units higher at 32/24 °C than at 22/17 °C. In vitro dry matter disappearance (IVDMD) of the normal-tannin leaves was approximately 20 percentage units less than that of the low-tannin leaves, and was not influenced by temperature. Stems were more digestible than the leaves in both cultivars, but normal-tannin stems were slightly less digestible than the low-tannin stems. The IVDMD of low-tannin stems was 6 units lower at 32/24 °C than at 22/17 °C. Future breeding efforts with low-tannin sericea should place emphasis on lower tannin and NDF concentrations because both these components tend to increase with temperature and bear negative associations with IVDMD.Key words: Lespedeza cuneata, neutral detergent fiber, crude protein, forage quality

ABSTRACT   EFFECT OF UTILIZATION OF VIRGIN COCONUT OIL (VCO) IN THE DIET ON PIG PERFORMANCE. Utilization of fats and oils in pig diets is of great importance due to their high energy value. VCO is obtained by cold press processing of the kernel from the coconut fruit. Utilization of virgin coconut oil (VCO) in the diets on pig performance.  The present study was designed to elaborate the effect of utilization of VCO in the diets on energy and protein digestibility of growing pigs. The experiment was conducted using 20 castrated male pigs aged 1.5 - 2.0 months weighing 12,0±2,0 kg. The data were analyzed according to the linear model procedure for ANOVA appropriate for Randomized Block Design with 5 treatments and 4 replications. Treatments were formulated as follow: R0 = 100% control diet + 0% VCO; R1 = 99.5% control diet + 1.0% VCO; R2 = 98.0% control diet + 2.0% VCO; R3 = 97.0% control diet + 3.0% VCO; and R4 = 96.0% control diet + 4.0% VCO. Parameters measured were: daily feed intake, daily gain, daily water consumption. The results showed that the utilization of VCO up to 4% in the diets had no significant effect (P > 0.05) on daily feed intake, daily gain, daily water consumption of pigs. It can be concluded that the addition of VCO up to 4.0% in the diets has no significant meaning on pig performance.   Key words: Virgin coconut oil (VCO), Performance, Growing pigs

Two Stages

We evaluated heifer post-weaning residual feed intake (RFI) classification and cow age on dry matter intake (DMI) at two stages of production. Fifty-nine non-lactating, pregnant, (Study 1) and fifty-four lactating, non-pregnant (Study 2) commercial black Angus beef cows were grouped by age and RFI. Free-choice, hay pellets were fed in a GrowSafe feeding system. In Study 1, cow DMI (kg/d) and intake rate (g/min) displayed a cow age effect (p < 0.01) with an increase in DMI and intake rate with increasing cow age. In Study 2, cow DMI (kg/d) and intake rate (g/min) displayed a cow age effect (p < 0.02) with an increase in DMI and intake rate with increasing cow age. Milk production displayed a cow age × RFI interaction (p < 0.01) where both 5–6-year-old and 8–9-year-old low RFI cows produced more milk than high RFI cows. For both studies, intake and intake behavior were not influenced by RFI (p ≥ 0.16) or cow age × RFI interaction (p ≥ 0.21). In summary, heifer’s post-weaning RFI had minimal effects on beef cattle DMI or intake behavior, however, some differences were observed in milk production.
