Abstract Butyrate (UltraMix GF; Adisseo) is known to enhance ruminal papillae development for transitioning calves to dry feed. The hypothesis was that butyrate would be beneficial to neonatal calf growth performance. Eighty 2- to 5-d old Holstein bull calves were assigned to one of 2 treatments using a randomized complete block design. Treatments were: 1) control: no butyrate; or 2) butyrate: 0.3% butyrate added to milk replacer (MR). Calves were fed 2x/d at 0630 and 1800 h along with free choice water and a 22% CP mini-pelleted calf starter (CS). The MR was fed at 0.567 kg/d for d 1–14, then increased to 0.85 kg/d for d 15–42, and feeding reduced to 1x/d for d 42–49 with weaning occurring after the 49-d experimental period. Calves fed butyrate demonstrated greater (P < 0.04) ending body weight (BW; 54.7 and 56.2 kg, for control and butyrate, respectively), BW gain (29.0 and 31.7 kg), and average daily gains (ADG; 591.3 and 647.7 g/d), compared with calves fed control. Dry matter intake (DMI) was similar (P > 0.10) for both treatments, but the number of d required for calves to consume 0.9 kg CS for 3 consecutive days (47.3 and 45.7 d) was lower (P < 0.05) for calves fed butyrate compared with calves fed control. Feed conversions were improved (P < 0.05) for calves fed butyrate (0.53 and 0.58 kg/kg) compared with calves fed control. At the end of the 49-d study, withers height tended (P < 0.10) to be greater for calves fed butyrate (85.2 and 86.0 cm) compared with calves fed control, while the remaining frame measurements (hip height, hip width, body length, and heart girth) and fecal scores were similar (P > 0.10) for calves fed both treatments. Feeding neonatal calves butyrate in the MR improved growth performance and reduced the days to transition calves to CS.

Abstract Several calf studies demonstrate advantages when feeding greater protein and/or milk solids amounts, however studies comparing 2x/d versus 3x/d feeding are limited. Forty 2- to 5-d old Holstein bull calves were blocked by body weight (BW) and randomly assigned to 1 of 2 treatments. Treatments were: 1) 2X: milk replacer (MR) fed 2x/d; and 2) 3X: MR fed 3x/d. The MR was fed at 15% solids at 0630 and 1800 h and the 3rd 3X feeding was at 1200 h. 2X calves were fed MR at 0.567 kg/d for d 1–14, increased to 0.85 kg/d for d 15–35, and reduced to 1x/d at 0.425 kg/d for d 36–42 for the 42 d study. 3X calves were fed MR 0.851 kg/d for d 1–14, increased to 1.275 kg/d for d 15–35, and reduced to 1x/d at 0.425 kg/d for d 36–42. Calf starter (CS) and water were free choice. Initial BW was a significant (P < 0.01) covariate and BW (55.6 and 57.3 kg for 2X and 3X, respectively) tended (P < 0.09) to be greater for calves fed 3X compared with 2X fed calves, but BW gains (25.5 and 27.7 kg) were similar (P > 0.10). A treatment by week interaction (P < 0.01) demonstrated variable BW gains. Intake of CS (0.28 and 0.13 kg/d) was approximately 63% lower (P < 0.04) for calves fed 3X compared with calves fed 2X. Feed conversions (0.65 and 0.60 kg/kg) were greater (P < 0.04) for calves fed 2X compared with calves fed 3X. Calves fed 2X had less scours (fecal score=0; 34.3 and 29.7 d) compared with 3X fed calves. Providing an additional MR feeding demonstrated minimal BW gains. Providing a 3rd daily feeding greatly reduces CS intake and inhibits the transition needed for weaning calves.

Abstract A botanical extract (BE; garlic oil, anise oil, cinnamaldehyde, rosemary, and thyme blend) has been shown to enhance dry matter intake (DMI) and gut health, while eubiotics (EU; lactobacillus acidophilus fermentation product), has been shown to improve gut health and growth performance of growing Holstein calves. The hypothesis was the combination BE and EU could be synergistic to post-weaning neonatal calf growth performance. Seventy-seven (77) Holstein bull calves from a previous milk replacer trial were randomly assigned to 1 of 4 treatments using a 3 wk experimental period. Treatments were: 1) Control: Calf starter (CS) without BE or EU; 2) BE: CS with 275.6 g/ton of an experimental BE (Adisseo North America, Alpharetta, GA); 3) EU: CS with 0.22% EU (RumaCell DF 5G; Pacer Technology, Murtaugh, ID); and 4) BE&EU: CS with added BE and EU. The 22% crude protein CS was a mini-pellet and fed for ad-libitum consumption with amounts fed and orts recorded daily. Calves fed EU demonstrated greater (P < 0.05) body weight (BW; 81.3, 80.8, 84.8, and 84.2 kg for Control, BE, EU, and BE&EU, respectively) compared with calves fed Control and BE with calves fed BE&EU being intermediate and similar (P > 0.10). Calves fed BE demonstrated greater (P < 0.05) average daily gains (ADG; 965.5, 984.3, 1052.8 and 989.1 g/d) compared with calves fed Control with calves fed BE and BE&EU being intermediate and similar (P > 0.10). The DMI (2.19, 2.18, 2.31, and 2.14 kg/d) and feed conversions (0.45, 0.46, 0.45, and 0.45 kg BW gain/kg DMI) were similar (P > 0.10) among calves fed all treatments. Blood urea nitrogen concentrations (14.7, 14.6, 14.9, and 13.4 mg/dL) were similar (P > 0.10) among calves fed all treatments. Feeding a EU improved BW of weaned growing Holstein bull calves, but the BE and EU combination was not beneficial for enhancing growth performance.

The aim of this study was to assess the effects of dietary probiotic enhanced liquid acidifier combined with mannan-rich fraction on growth performance, nutrients digestibility in growing pigs. Thirty [(Duroc×Yorkshire)×Landrace] pigs with the average initial BW of 36.75±1.57 kg were allocated into three treatments by a randomized complete block design. There were five pens per treatment with six pigs per pen. Dietary treatments include: 1) CON (basal diet); 2) T1 (basal diet+probiotic 0.1%) and 3) T2 (basal diet+probiotic+mannan rich fraction 0.2%). the data were analyzed as a randomized complete block design using of SAS University Version 4.0. The model included the effects of block (replication) and treatment. Pen served as the experimental unit. During the entire experimental period of 6 weeks, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG significantly (p<0.05). Also, digestibility of DM and N tended to increase. To sum up, results in this experiment indicated that dietary [(probiotik×acidifier)×mannan-rich-fraction]  supplementation had a positive effect on growing pigs performance and nutrient digestibility

Abstract The milk-fed calf has a requirement for amino acids (AA) instead of crude protein (CP); however, most milk replacers (MR) are still formulated for CP concentrations. Previous work has demonstrated that feeding a modified MR (24:20; CP:fat @ 0.64 kg/d) improved calf growth performance compared with standard (20:20 @ 0.57 kg/d) and accelerated MR (26:16 @ 0.78 kg/d). The 56-d study objective was to determine if feeding an MR formulated using synthetic AA to achieve the AA concentrations of a 24:20 MR while reducing CP results in similar or enhanced growth performance and/or reduce cost compared with standard MR formulations. Eighty 3- to 5-d-old Holstein bull calves received in two lots (40) within the same week were blocked by body weight (BW) and randomly assigned to one of four MR treatments consisting of 20:20 (20), 22:20 (22), 24:20 (24), and a 22:20 having the AA concentrations of the 24, but with reduced CP (22AA). All MR contain decoquinate and were fed at 0.57 kg/calf daily split into 2×/d feeding for 14 d via bucket, increased to 0.85 kg/calf daily in two feedings until 35 d, and then fed 1×/d at 0.41 kg/calf daily with weaning after day 42. Calves were housed in straw-bedded hutches with ad libitum access to water and pelleted calf starter (CS). All data were statistically analyzed as a randomized complete block design with block considered random with week as a repeated measurement. Initial BW was similar (P &gt; 0.10) across all treatments (42.4 ± 2.2 kg). Calves fed 22AA MR demonstrated greater (P &lt; 0.05) BW compared with calves fed the 24 MR, and calves fed the 20 and 22 MR being intermediate and similar (P &gt; 0.10; 78.7, 78.8, 76.5, and 81.8 kg for 20, 22, 24, and 22AA, respectively). CS intake was greater (P &lt; 0.05) for calves fed 22AA (0.74, 0.78, 0.65, and 0.81 kg/d) compared with calves fed the 20 and 24, but similar (P &gt; 0.10) to calves fed 22. Calves fed 24 MR demonstrated the lowest CS intake. This study demonstrates that similar growth performance can be achieved by feeding an AA fortified MR having a lesser CP concentration, which might reduce feed costs.

Abstract Two-hundred and forty Continental × English beef steers (allotment BW = 365 kg [SD 22.5]) were used in a randomized complete block design feedlot study to evaluate the effects of bedding application during the finishing phase. Steers were allotted to 30 concrete surface pens (n = 8 steers/pen) at the Ruminant Nutrition Center (RNC) in Brookings, SD. A common diet was fed that contained 2.09 Mcal/kg of NEm and 1.39 Mcal/kg of NEg and provided 30 g/ton of monensin sodium to diet DM. Pens were assigned to 1 of 2 treatments: 1) No bedding applied (NO) or 2) 1.8 kg (as-is basis) of wheat straw bedding/steer/d (BED). The first 9 pen replicates began on test 14 d prior to the last 6 pen replicates. Pen was the experimental unit; an α of 0.05 determined significance. This study was part of a factorial experiment that included steroidal implant. No interactions were detected (P ≥ 0.09). Daily ambient temperature (n = 183) averaged 4.33°C [SD 3.21] during the study. Dry matter intake was increased (P = 0.01) by 5.8% in BED compared to NO. Carcass-adjusted ADG (P = 0.01) and G:F (P = 0.01) were increased in BED by 21.0% and 14.4%, respectively. Carcass-adjusted final BW and HCW tended to differ (P ≤ 0.07) between NO and BED. Cattle from NO required an additional 35 days to achieve similar final live BW. Rib eye area (P = 0.69) did not differ between NO and BED. Dressing percentage (P = 0.01; 63.29 vs. 62.30 ± 0.410%), backfat (P = 0.01; 1.19 vs. 1.09 ± 0.410 cm), marbling (P = 0.01; 475 vs. 437 ± 6.6), and yield grade (P = 0.03; 2.95 vs. 2.81 ± 0.045) were increased in NO. Estimated metabolic rate was elevated (P = 0.02; 0.0995 vs. 0.0948 ± 0.013 Mcal/BW0.75, kg), for NO vs. BED. Bedding improved feedlot finishing phase growth performance and gain efficiency during finishing in eastern South Dakota.

Kirk and Cooper (1983) reported two experiments in which the growth performance and carcass conformation of intensively fed dairy-bred bulls was improved by sequential implantation with Zeranol®. Two further studies have been conducted in which there has been repeat implantation of Zeranol® and detailed carcass dissection to measure precisely the effects on carcass quality.In trial A, 16 Holstein bull calves were purchased from pedigree breeders and weaned at eight weeks of age, when they were divided into two groups of eight, balanced by weight. From 8 to 12 weeks they were given commercial rearing pellets followed by a. commercial pencil and hay was given ad libitum. From 12 weeks onwards a cereal mix was offered ad libitum, formulated to give 13 MJ/kg dry matter, 160 g/kg crude protein. Hay was withdrawn from 14 weeks of age. At eight weeks of age, half the animals were implanted with 36 mg Zeranol® (Ralgro, Crown Chemical Company, Kent), and re-implanted a further three times every 70 days. Five blood samples were taken from all animals over a 15h period at about 8, 14, 33 and 43 weeks of age.

Abstract Two experiments were conducted to investigate effects of dietary flavor as a feed additive on growth performance of weaned pigs. The flavor used in experiments was a commercial product (Luctarom®, Lucta Guangzhou, China) containing milky cream flavor. In Exp. 1, 72 weaned pigs (initial BW = 6.51 ± 0.21 kg) were randomly assigned to 2 dietary treatments (4 pigs/pen; 9 replicates/treatment): an experimental diet based on corn and soybean meal (CON1) and CON1 supplemented with 0.05% flavor (FLA). In Exp. 2, 72 weaned pigs (initial BW = 6.66 ± 0.32 kg) were randomly assigned to 2 dietary treatments (4 pigs/pen; 9 replicates/treatment): a commercial diet based on corn and soybean meal with spray dried plasma, fish meal, and zinc oxide (CON2) and CON2 supplemented with FLA. Pigs were fed respective dietary treatment for 6 weeks. Growth performance was measured on day 1, 7, 14, 21, and 42 after weaning. Data were analyzed using the PROC GLM procedure of SAS. The statistical model for every measurement included dietary effect and BW as a covariate in a randomized complete block design (block = BW). In Exp. 1, pigs fed FLA tended to increase ADG (0.493 vs. 0.451 kg/d; P &lt; 0.10) during the experimental period compared with those fed CON1. However, there were no differences in ADFI and G:F between CON1 and FLA. In Exp. 2, pigs fed FLA had greater ADG (0.548 vs. 0.463 kg/d; P &lt; 0.05) and tended to increase ADFI (0.870 vs. 0.753 kg/d; P &lt; 0.10) during the experimental period than those fed CON2. However, there was no difference in G:F between CON2 and FLA. In conclusion, the addition of dietary flavor in experimental and commercial nursery diets improved growth performance of weaned pigs.

Abstract Gut health is critical for neonatal calves, and nutritional technologies are needed for disease and stress prevention. Previous work feeding Monensin (MON) in combination with a blend of essential oils and a proprietary cobalt source (EOC) blend had demonstrated improved calf gut health and growth performance. The objective was to evaluate MON and EOC alone or in combination on calf growth performance. Eighty (80) new born Holstein calves were randomly assigned to one of four treatments arranged in a 2 x 2 factorial (MON and EOC). Treatments were: 1) Control without MON or EOC added to the calf starter (CS); 2) MON: 50.8 mg/kg CS (Norvikon Biotechnology Co., Hunan, China); 3) EOC: 44.1 mg/kg CS (Rum-A-Fresh, Ralco Inc. Marshall, MN); 4) MON+EOC: MON and EOC added to CS. Calves were fed colostrum followed by whole milk through weaning at 42 d, while CS was fed ad libitum through the 70-d experimental period. The MON by EOC interaction was found to be nonsignificant (P &gt; 0.41) for growth performance. Calves fed without or with MON demonstrated similar (P &gt; 0.70) body weight (BW; 68.7 and 68.9 kg without and with MON, respectively), while calves fed EOC demonstrated greater (P &lt; 0.01) BW (67.3 and 70.4 kg without and with EOC, respectively) compared with calves fed without EOC. Calves fed a CS containing MON were similar (P &gt; 0.47) in ADG (0.88 and 0.91 kg/d) compared with calves fed without MON; however, calves fed a CS with EOC increased (P &lt; 0.01) ADG (0.84 and 0.95 kg/d) 13% through the 70 d experimental period compared with calves not fed EOC. These data demonstrate that EOC and MON fed in combination was not beneficial for enhancing growth performance, but that calf growth performance can be improved with EOC compared to MON.

Forty Holstein bull calves (73.6 ± 6.3 kg) were used in a randomized complete block design to determine if varying the corn-to-barley ratio in the diet affects growth, diet digestibility and carcass quality of grain-fed veal calves. Five diets consisting of corn:barley ratios of 100:0, 75:25, 50:50, 25:75, 0:100 were offered along with a protein supplement (43.6% CP). Grain-to-protein supplement ratios were 2:1, 3.5:1 and 5:1 for the starting, growing and finishing phases, resulting in diets of 23.5, 20.3, and 18.7% CP, respectively. Incidence of diarrhea increased with an increase in dietary barley (P < 0.05). Apparent digestibility of diets decreased as the proportion of barley increased (P < 0.01). Throughout the experiment, DMI was the highest for diets containing 75% barley and the lowest for those containing 100% corn (P < 0.01). Average daily gains behaved in a quadratic manner during the starting phase only (P < 0.01). This effect became linear during the growing and finishing phases, with ADG decreasing as dietary barley increased (P < 0.01). Average feed to gain ratio increased linearly with dietary barley content (P < 0.01). Hot carcass weights and yields decreased linearly with increasing proportions of barley (P < 0.01). Carcass color was not affected by treatments. Carcass classification tended to decrease as dietary barley increased. The results indicate that compared with barley, the use of corn improves performance and diet digestibility of grain-fed veal. Key words: Veal calves, corn, barley, starch digestion, carcass quality

ABSTRACT The objective of this study was to evaluate the phytomorphological parameters of soybean in a crop-livestock system inoculated with Azospirillum brasilense. The experiment was conducted in Santa Maria, Brazil, for two agricultural years (2 Paper extracted from the doctoral thesis of the first author. 012/2013 and 2013/2014) in a randomized complete block design with three replications. In the winter, the black oat and ryegrass pasture was managed with sheep under different grazing systems: (I) - a conventional grazing (CG) system, where the animals remained in the pasture throughout the experimental period without any pasture height control; (II, III, and IV) - systems with post-grazing pasture heights of 10, 20, and 30 cm, respectively; and (NG) - one control without grazing. All treatments received two nitrogen doses (50 and 100 kg ha-1) and inoculation or no inoculation (A. brasilense). The soybean cultivar BMX Potência RR was sown using no-tillage on 16 November 2012 and 1 December 2013. In each plot, seven rows of plants with spacing of 0.45 m were used, and in four rows, the seeds were inoculated with the bacterium A. brasilense. The phytomorphological variables and grain productivity were evaluated. In a croplivestock system, soybean has better productivity when established on black oat and ryegrass pasture managed with post-grazing pasture heights of between 20 and 30 cm. Areas under conventional grazing in the winter led to smaller soybean plants with lower first and last pod heights. Inoculation with A. brasilense should not be used alone in soybean cultivation.
