“…The same result was reported by Rogers et al (1995), where there was an increase in animal performance without affecting the dry matter intake. Heker et al (2018), when evaluating the DMI of steers confined and supplemented with MO alone or MO combined with VM, also did not obtain any difference between treatments. Squizatti (2019) evaluated 5 cannulated cattle, adapted for 14 days and supplemented with MO alone (30 mg kg -1 ) or MO + VM (30 mg kg -1 + 25 mg kg -1 ) and found no differences in DMI corroborating the present experiment.…”

“…The ADG found by the same author showed no synergy between the additives, remaining at 1.240 kg day -1 . Heker et al (2018) examined the performance of confined steers receiving MO combined with VM and/or essential oils and found that the ADG for treatment with MO was 1,329 kg day -1 versus 1,559 kg day -1 in the combination of MO and VM, these data are in line with data of the present experiment with 1,636 kg day -1 versus 1,799 kg day -1 of the average of the treatments receiving different doses of MO and VM, that is, the combination of these provided greater daily gain regardless of the dosage provided.…”

“…As for the rumination behavior and time, an experiment carried out by Sitta (2011) showed no difference with the inclusion of MO and/or MO combined with VM. According to Heker et al (2018), these results can be explained by the same physical characteristic of the feed, being different only the supplementation offered to the animals. Pereira et al (2015) evaluated the diet with inclusion of MO in different dosages, and also observed no difference in the number of trips to the feeder, with an average value of 15.53 times day -1 .…”

The objective was to evaluate the associative effect of monensin sodium to virginiamycin on the performance, dry matter intake, apparent digestibility and ingestive behavior of steers in the initial feedlot phase. The experiment lasted for 30 days, divided into two experimental periods. Thirty-six Angus Nellore steers, non-castrated, with a mean age of 10 months and an average weight of 300 kg, were divided into 18 pens. Animals were assigned to three treatments with six replications each, with the inclusion of the following additives: T1-monensin sodium, dose of 200 mg day-1; T2-monensin sodium, dose of 125 mg day-1 + virginiamycin, dose of 125 mg day-1; and T3-monensin sodium, dose of 200 mg day-1 + virginiamycin, dose of 125 mg day-1. All experimental procedures were previously submitted to the UNICENTRO Committee for Ethics in Animal Experimentation (CEUA), and were approved for execution (Official Letter 021/2019). The combination of monensin sodium with virginiamycin at a dose of 200 mg + 125 mg animal day-1 showed greater (P < 0.05) average daily weight gain (1.919 kg day-1) and better feed conversion (4.27 kg DM kg of weight gain-1) compared to diets with monensin alone (200 mg animal day-1) or monensin combined with virginiamycin (125 mg + 125 mg animal day-1), even with no significant (P> 0.05) difference in DM intake, with a mean value of 7.88 kg animal day-1. Regardless of the isolated or combined supplementation of the additives, no significant differences were detected in the analysis of the feeder and feces scores, ingestive behavior, and rectal temperature or infrared thermography during the evaluation period. The combination of monensin sodium with virginiamycin at 200 mg + 125 mg animal day-1 proved to be efficient in the initial feedlot period, determined by the greater weight gain and better feed conversion observed in this study.

“…In an earlier report, Benchaar et al [ 58 ] concluded that there were no interaction effects with the combination MON + EO (350 mg/day and 2000 mg/day, respectively) on productivity and ruminal fermentation in lactating dairy cows. More recently [ 59 ], an experiment was performed to evaluate the effects of supplemental MON (200 mg/day) alone or combined with EO (1500 mg/day) on angus steers consuming a silage-based diet. Steers that were fed with the MON + EO combination had lower ADG and feed efficiency than steers that received MON alone.…”

With the aim of evaluating the effect of combining an antibiotic ionophore with plant extracts and probiotics on the productive efficiency (performance and carcass) during the last phase of lamb fattening, 24 Pelibuey × Katahdin male lambs (38.47 ± 3.92 kg, initial weight) were fed with a high-energy diet during for 56 days, and assigned, under a complete randomized block design experiment to one of the following supplement treatments: (1) 28 mg of monensin/kg diet DM supplemented alone (MON), (2) combination of MON plus 2 g/kg diet of a product contained Bacillus subtilis 2.2 × 108 CFU kg diet DM (MON + BS), (3) combination of MON + BS plus 300 mg essential oils/kg diet DM (MON + BS + EO), and (4) BS alone. At the end of the feeding trial (56-d), lambs were slaughtered and carcass variables were measured. Compared to the rest of the treatments, combining MON with BS improved dietary NE by 3.4% and the efficiency of utilization of dietary energy consumed. Inclusion of EO in the MON + BS combination resulted in a similar average daily weight gain (ADG) and feed efficiency (GF) when compared with MON + BS, but showed a lower dietary net energy (NE), hot carcass weight, and dressing percentage. Lambs receiving BS alone showed greater average ADG and dry matter intake (DMI) than lambs receiving MON + BS + EO, but similar feed GF and dietary NE. There were no treatment effects on tissue composition, whole cut, or visceral organ mass. It was concluded that combining probiotics with the ionophore monensin can improve the efficiency of dietary energy utilization in the last phase of finishing. Probiotics supplemented alone result in greater ADG without a difference in dietary energy efficiency when compared with MON alone. Inclusion of EO in the MON + BS combination did not show advantages; on the contrary, it reduced carcass weight and dressing percentage. It is necessary to further research the potential complementary effects of combining diverse sources of natural additives with synthetic antibiotics.

“…Monensin (MON) is an ion carrier antibiotic with the potential to regulate rumen fermentation and improve animal performance [12,13]. As an antimicrobial supplement, monensin has demonstrated its ability to enhance daily weight gain, feed conversion efficiency, proportion of lean meat, and area of the eye muscle in ruminant animals [14][15][16]. It occupies an important position in the animal husbandry industry and brings great convenience and economic benefits to people.…”

This study was conducted to evaluate the influences of supplementing Ampelopsis grossedentata flavonoids (AGF) on the rumen bacterial microbiome, plasma physiology and biochemistry, and growth performance of goats. Twenty-four Nubian kids were randomly allocated to three dietary treatments: the control (CON, basal diet), the 1.0 g/kg AGF treatment (AGF), and the 12.5 mg/kg monensin treatment (MN). This trial consisted of 10 days for adaptation and 90 days for data and sample collection. The results reveal that Bacteroidetes, Firmicutes, and Proteobacteria are the dominant phyla in kids’ rumen. Compared with the CON group, the alpha diversity in the MN and AGF groups significantly increased (p < 0.01). Beta-diversity shows that rumen microbial composition is more similar in the MN and AGF groups. LEfSe analysis shows that Prevotella_1 in the AGF group were significantly higher than those in the MN and CON group. The high-density lipoprotein cholesterol and glucose levels in the AGF group were significantly higher than those in the CON group (p < 0.05), whereas the low-density lipoprotein cholesterol, glutamic-pyruvic transaminase, and alkaline phosphatase levels exhibited the opposite trend. The average daily gains in the AGF and MN groups significantly increased, while the feed-to-gain ratios were significantly decreased (p < 0.05). The results suggest that adding AGF to the diet improves microbial composition and has important implications for studying juvenile livestock growth and improving economic benefits.
