The objective was to evaluate the effects of feeding two different commercially available blends of essential oils to finishing steers to replace conventional feed additives in feedlot diets. Angus-based crossbred steers (N=43; starting BW=466±31 kg) were used in a randomized complete block design. Steers were randomly assigned to four different dietary treatments for the 100-day finishing period in which steers were fed high moisture corn/alfalfa silage/soybean meal diets. Dietary treatments included a negative control (no additives; CON), a positive control (33 mg/kg monensin and 11 mg/kg tylosin added to the diet; M/T), and two different proprietary blends of essential oils [EO-1: 1 g/steer/day Victus Liv (DSM Nutritional Products) and EO-2: 4 g/steer/day Fortissa Fit 45 (Provimi Canada ULC)]. Growth performance, carcass characteristics, meat quality, sensory attributes (excluding juiciness), most fatty acid parameters, and shelf-life (color and lipid oxidative stability) were generally unaffected by the inclusion of two different commercially available essential oil blends when compared with both a negative control (CON) and a positive control (M/T). This indicates that commercially available essential oil blends may show promise as a replacement to conventional feed additives like antibiotics without causing negative effects to meat quality, storage stability, and eating experience.

Abstract The effects of PS were determined as a concentrate added to feed and of the days it was short-term and long-term fed to fattening dairy steers on their growth performance, carcass characteristics, meat quality, and economic return. The experimental units comprised 36 feedlot dairy steers arranged as a 2 ⋅ 3 factorial in a completely randomized design. The first term (diet factors) consisted of ground corn (GC), ground cassava (CA), or pineapple stem starch (PS) at 37% dry matter (DM) in the concentrate. The second term (feeding factors) consisted of feeding the concentrate from 1 to 206 days (short-term feeding) or from 1 to 344 days (long-term feeding). At the end of the feeding term periods, the animals were slaughtered and the growth performance, carcass characteristics, and meat quality were evaluated. The average daily gain (ADG), feed:gain ratio, dry matter intake (DMI), hot carcass and cool carcass percentages, and backfat thickness were greater for steers on short-term than on long-term feeding. Feeding the different starch sources had no negative influence on the growth performance, carcass characteristics, and meat quality. However, the ADG of steers fed PS tended (P = 0.07) to be higher than for those fed GC or CA. In addition, the concentration of the fatty acid C14:1 in the longissimus dorsi muscle was the highest in steers fed CA. Different starch sources had similar values for saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA.) Long-term feeding increased MUFA. Pineapple stem starch could be a useful feed ingredient for feedlot steers as an alternative starch source for energy.

Abstract This study examined the effects of feeding two different commercially available blends of essential oils with or without benzoic acid on growth performance, carcass characteristics, and meat quality of finishing steers. Angus-based crossbred steers (N = 76; allocation BW = 429 ± 30 kg; starting BW = 466 kg ± 31 kg) were assigned by allocation weight into two blocks. Within each block, steers were randomly assigned to one of seven dietary treatments for a 100 d finishing period. Treatments were: 1) a negative control with no additives; 2) a positive control with supplementation of monensin/tylosin; 3) essential oil blend #1 (Victus Liv, DSM Nutritional Products); 4) essential oil blend #2 (Fortissa Fit 45, Provimi Canada); 5) benzoic acid (VevoVitall, DSM Nutritional Products); 6) a combination of essential oil blend #1 and benzoic acid; and 7) a combination of essential oil blend #2 and benzoic acid. All feed additives were supplemented at dosage levels according to manufacturer instructions. Growth performance, carcass characteristics, and meat quality were evaluated. Individual animal feed intake was collected using an Insentec feeding system, therefore steer was the experimental unit for all analyses. Data were analyzed using a RCBD with fixed effect of treatment and random effect of block. Final BW, ADG, DMI, and G:F were similar (P > 0.25) among treatments. There were no treatment differences (P > 0.15) for the carcass characteristics or the meat quality parameters evaluated in this study. Overall, steers supplemented with the commercial blends of essential oils with or without benzoic acid had similar growth performance, carcass characteristics, and meat quality parameters as steers fed CON or M/T, indicating that these products may have potential as replacements for monensin and/or tylosin.

The objective of this study was to evaluate the associative effect of monensin sodium to virginiamycin and/or essential oils on performance, consumption of nutrients and dry matter, apparent digestibility, feeding behavior and carcass characteristics of feedlot finished steers. The experiment lasted 106 days with 10 days of adaptation and 96-day trial, and had 32 crosses angus steers, average age 12 months and average weight of 376 kg, divided into 16 stalls, the weighing took place every 21 days and at the end of the experiment. The treatments consisted of the combination of the following additives to the diet included: Monensin sodium, 200 mg day-1 (MO); Monensin sodium, a dose of 200 mg day-1 + essential oil dose of 1.5g day-1 (MO+EO); Monensin sodium, a dose of 200 mg day-1 + virginiamycin, 200 mg day-1 (MO+VI); Monensin sodium, 200 mg day-1 + essential oil dose of 1.5g day-1 + virginiamycin day, 200 mg day-1 (MO+EO+VI), each treatment had four repetitions, where each repetitions consisted of a bay with two animals. The MO+VI association in relation to MO only increase in average daily gain (ADG) of 24.44%, 22.35%, 21.10% and 17.31% in weighing 42, 63, 84 and 96 days, similar the combination of MO+EO+VI which provided an improvement of 21.94%, 13.59%, 15.45% and 14.75% respectively in the same weightings. The daily carcass gain and carcass overall gain were higher in associations MO+VI and MO+EO+VI and provided an average gain of 16.67 kg more compared to MO and MO+EO. In the parameters feed efficiency, dry matter intake and nutrient expressed in kg day-1 and percentage of live weight were not observed differences (P > 0.05) between treatments. Data on apparent digestibility, feeding behavior and carcass characteristics did not show statistical difference between treatment, except for fat thickness which was higher when associated with any of the additives to the MO, and farm weight was higher in associations containing VI. Associating MO+VI or MO+EO+VI proved to be best in this work compared to MO+EO or only MO in the diets of steers in termination.

Any evaluation of breeds or production systems for beef must consider effects on production, carcass and meat quality characteristics. Holstein-Friesian (HF) cattle are bred for dairy traits only, while Norwegian dairy cattle (NOR) have been selected with some emphasis on beef characteristics. A comparison of production data from bulls of these two breeds has been presented previously (Kirkland et al., 2005). The objective of the present study was to evaluate specific carcass and meat quality parameters of HF and NOR bulls.
