Abstract Garlic products have been reported to have antimicrobial effects and may trigger anemia in horses, but their direct impact on feedlot cattle has not been detailed. With increased free-choice feeding of garlic-infused mineral supplements to beef cattle, it is important to evaluate this strategy’s impact on the animals’ health and the potential impact on carcass qualities. This 2-yr study recruited 208 crossbred feedlot steers in a supplementation trial using a completely randomized design. Each year, 104 steers were assigned to 1 of 4 groups that received either non-garlic mineral supplement (MS), MS + 0.3% garlic-oil-based premix (GOil), MS + 2.5% garlic powder (LGP), MS + 5% garlic powder (HGP). Feed and supplements were provided on an ad-lib basis and were measured for each steer with automatic feeding units. The study evaluated health indicators such as blood parameters and internal parasites. At harvest, carcass characteristics (including the incidence of liver abscesses) were assessed for all steers. The groups consumed between 156 and 208 g/d of the supplement over the two years, with the MS group having a lower overall supplement intake than other groups. The average daily consumption of garlic products in GOil, LGP, and HGP were approximately 0.6g/d, 5.2g/d, and 10.1g/d, respectively. There was no difference in total fecal egg counts (P = 0.45) among the groups. There was no association between the treatment groups and incidences of liver abscess scores (P = 0.10) nor carcass grade outcomes (P = 0.84). Further, there were no differences in hot carcass weight (P = 0.90), rib eye area (P = 0.34) and carcass backfat thickness (P = 0.99). All blood parameters evaluated were within normal ranges for all groups. The results suggest that infusing commercial garlic products into mineral supplements is not associated with undesirable effects on cattle health or carcass characteristics.

Abstract The objective of this study was to evaluate the effect of increasing quantity of soy-hulls in diets of feedlot cattle offered free-choice hay on finishing performance, roughage intake, and carcass characteristics. Sixty heifers and 54 steers, Angus*Simangus-crossbreds, were used in a randomized complete block design. Cattle were stratified by sex and weight and randomly assigned to 1 of 12 pens. Treatment 1 consisted of 5% soy hulls (SH; 5%SH), 70% cracked corn (CC), 15% dry distiller grains with soluble (DDGS), 10% mineral supplement (SUP). Treatments 2 (10%SH) and 3 (15%SH) included an additional 5% and 10% SH in place of CC, respectively. Hay was offered ad libitum and separate from the concentrates in different bunks, both concentrate and forage were fed in GrowSafe units. Data were analyzed as a complete block design and mean differences in group means were determined using polynomial contrast [lineal (L) and quadratic (Q)]. There was a quadratic effect of soy hull inclusion on final body weight (fBW) and concentrate intake (Q-P ˂ 0.05); 5%SH and 15%SH had a greater fBW and concentrate intake compared to those fed 10%SH. Gain to feed ratio was not affected by treatments (L-P ≥ 0.33). There was a linear effect of SH on hay intake (L-P ˂ 0.05) with cattle fed 5%SH consuming less hay than those fed 15%SH. There was no effect on ribeye area, yield grade, or backfat (L-P ≥ 0.35; Q-P ≥ 0.14). Hot carcass weight tended to quadratically respond to dietary treatments (Q-P < 0.10), while marbling score tended to be linearly decreased by increased SH inclusion (L-P = 0.09). Kidney-pelvic-heart fat was linearly decreased by increased SH inclusion (L-P ˂ 0.05). Results indicate that non-roughage NDF from by-products can effectively contribute to a reduction of roughage utilization in feedlot diets without compromising growth performance or carcass characteristics.

The Impact

Abstract The trial evaluated whether the addition of garlic powder increased mineral intake and reduced fly abundance in feedlot cattle. Following a completely randomized design, one hundred and four (104) spring-born crossbred steers (BW 529 ± 8kg) were recruited for the feeding trial at Lakeland College, Vermilion Alberta, Canada. Each steer was assigned to one of four treatment groups (26 steers each) where each group received a commercial feedlot mineral mixed with garlic powder to give a final supplement mix that contained either 2.5% or 5% garlic powder or 0.3% garlic-oil-based premix or 0% garlic product (as control). The animals received a feedlot ration. The different treatment groups were kept within side-by-side pens, each equipped with water troughs and automatic feeding equipment to measure individual feed and mineral consumption. Feed and mineral supplements were provided ad libitum. Differences were observed for mineral intake (P = 0.003), ADG (P = 0.002) and feed conversion efficiency (P = 0.01). Compared to the control, mineral supplement consumption increased between 18 to 50% in groups that received garlic-infused supplements. Fly counts did not differ among the groups, in part, due to low overall fly abundance. While there were no differences (P = 0.21) in the length of time the steers spent consuming feed, differences existed for time spent consuming minerals (P = 0.002) and mineral bunk visits (P = 0.0003). There was no difference (P > 0.18) in DMI, final body weight or hot carcass weight among the different groups. The hematological and biochemical parameters were within normal ranges for healthy cattle, and there was no difference in carcass quality grades (P = 0.78). Even though the impact on fly-counts was inconclusive, the preliminary results show that including low-dose garlic powder could be a practical strategy of increasing mineral consumption without any associated negative health consequences.

Three factorial experiments were conducted to determine the relative feeding value of dry barley (DB) and high-moisture barley (HMB), and to evaluate the influence of method of ensiling (Pit vs. Harvestore® (HAV) silo), source of roughage (hay vs. silage), and level of concentrate (90 vs. 75%) on the performance and carcass characteristics of feedlot cattle. In exp. 1, 252 steers (initial wt 357 kg) were assigned on the basis of weight to six treatments (two pens × 21 animals per pen). A mixed diet consisting of 85.2% barley grain (dry matter (DM) basis) was offered free choice. The barley portion of the ration consisted of either 0, 25, 50, 75 or 100% DB with the balance being HMB from a pit silo. The sixth treatment consisted of feeding 100% HMB for the first 57 d and 100% DB for the remainder of the trial. Overall average daily gain (ADG) for steers fed 100% DB (1.70 kg d−1) was significantly higher than observed for animals fed 100, 75 or 50% HMB (1.46, 1.49 and 1.56 kg d−1, respectively). The kg of feed DM required per kg gain (FC) varied between 5.76 and 7.13 and was not (P > 0.05) influenced by treatment. No differences (P > 0.05) were observed in carcass characteristics. In exp. 2, 360 steers (initial wt 340 kg) were allotted on the basis of weight to six treatments designed to evaluate the effect of source (Pit vs. HAV) and level of HMB, in diets containing 10.2% silage, on animal performance. Overall ADG (1.11 – 1.17 kg d−1), FC (6.66 – 7.01) and carcass characteristics were similar (P > 0.05) for animals fed Pit HMB, HAV HMB and DB. In exp. 3, 264 weanling calves (initial wt 216 kg) were allotted on the basis of weight to six treatments which differed in type of barley (HMB vs. DB), source of roughage (hay vs. silage) and level of concentrate (75 vs. 90%; DM basis). The feeding period was 127 d. Daily gains varied between 0.78 and 0.91 kg d−1 and FC ranged from 6.40 to 7.10 and were not influenced (P > 0.05) by source of barley or source or level of roughage. While animals fed DB had significantly higher ADG than those fed HMB in exp. 1, the overall results from the three experiments indicate that on a DM basis HMB has similar feeding value to DB, and that there is no major difference between Pit and HAV-stored HMB for feedlot cattle.

Abstract The objective was to evaluate growth performance and carcass characteristics for feedlot cattle fed two sources of rumen protected capsaicin at two dose rates. A total of 450 steers, stratified by BW, were assigned into 30 pens. Pens were randomly assigned to receive 1 of 5 treatments containing (DM basis) of 86.2% barley grain, 6.0% barley silage, 6.2% canola meal, and 1.6% vitamin and mineral supplement. Treatments contained no additive (CON) or included a low or high dose of Nexulin (100 mg/d for NEXLO and 330 mg/d for NEXHI) or CapsXL (77 mg/d CAPLO or 250 mg/d for CAPHI). Steers averaged 507 kg BW at the start of the study and 686 kg at the end of the study (69 days on feed) with no differences among treatments (P > 0.28). Dry matter intake, ADG, gain:feed, dressing percentage, backfat thickness, and rib-eye area were not affected by treatment (P > 0.33). Steers fed CAPLO and NEXLO tended (P = 0.07) to have lesser marbling scores than CON, CAPHI and NEXHI. The proportion of steers in Canadian yield grades 1 and 2 did not differ among treatments, while those in yield grade 3 were greater (P = 0.03) in NEXLO (29%) than the CON (10.0%) and NEXHI (12.2%) treatments, with those fed CAPLO (20%) and CAPHI (19%) being intermediate but not different. Treatment did not affect the proportion of steers in quality grades B4, A, or prime, but tended to increase the proportion of steers grading AAA (P = 0.08) and decrease the proportion grading AA (P = 0.06). Overall, the data from this experiment suggest the potential for capsaicin to affect carcass yield grade, marbling score and quality grades without affecting DMI, ADG, or dressing percentage.

Eight herds of beef cattle from Northwestern Manitoba were selected for Cu supplementation trials during the 1974 and 1976 grazing season (four herds in each season). Supplementary Cu was provided as injectable Cu glycinate or as CuSO4 in a free-choice mineral supplement. The treatments were a combination of: (1) one dose of injectable Cu at the start of the pasture season; (2) two doses of injectable Cu, at an interval of approximately 90 days, with the first dose as in (1); (3) CuSO4 added to mineral supplements to provide 0.25 or 0.50% Cu; and (4) injectable Cu, one or two doses during the pasture season, plus 0.25% Cu as CuSO4 in the mineral supplement. Within each herd a cow and her calf were treated as a cow-calf unit. The concentration of Cu in blood serum was used as an indicator of the Cu status of cattle. Forage samples were analyzed for Cu, Mo and total sulfur, and absorption coefficients for Cu and available Cu were calculated. One dose of injectable Cu at the start of the pasture season, or the inclusion of 0.25% Cu as CuSO4 in the mineral supplement, was effective as a Cu supplement where dietary Mo and total S were less than 3 mg/kg and 3 g/kg dry matter, respectively. When Mo and total S concentrations were higher than 3 mg/kg and 3 g/kg dry matter, respectively, doses of injectable Cu provided at a 90-day interval or a Cu concentration greater than 0.25% in the mineral supplement were effective. More than 0.50% Cu, as CuSO4, was required where Mo and total S in forages were in excess of 10 mg/kg and 3 g/kg dry matter, respectively. Inclusion of CuSO4 in the mineral supplement was adequate as a supplement for cows, but the calves did not appear to consume adequate mineral. Injectable Cu was equally effective for cows and calves. An inadequate transfer of Cu via milk was indicated when a cow, but not its calf was provided with injectable Cu. The beneficial influence upon serum Cu of injectable Cu as opposed to Cu in the mineral supplement, depended upon whether the Cu requirement of the cow or its calf was to be met. The level of supplementation to prevent a drop in serum Cu over the pasture season depended upon the concentrations of dietary Mo and S, and their effect upon the coefficient of absorption for Cu.

Abstract One-hundred twenty crossbreed steers (initial body weight (BW) 566 ± 42 kg) were used to evaluate the interaction of protein source (PS) and non-roughage NDF content (NRFC) in finishing diets of feedlot cattle fed free-choice hay on performance and carcass characteristics. Steers were stratified by BW and randomly assigned to 8 pens (2×2 factorial) and fed for 104 ± 10 d. Four dietary treatments were investigated: 1) distillers’ dry grains with solubles (DDGS) and a low NRFC (DLF), 2) DDGS and a high NRFC (DHF), 3) soybean meal (SBM) and a low NRFC (SLF), 4) SBM and a high NRFC (SHF). Free-choice grass hay and concentrates were offered in a different bunk. Data were analyzed as a randomized complete block design. Do to the confounded effect of PS and protein intake, a linear regression was used to evaluate the effect of protein intake in growth performance. For gain to feed ratio (G:F) an interaction tended to occur (P = 0.10) between PS and NRFC. Steers on the DHF treatment had a lower G:F compared with SLF and SHF. Feeding SBM increased (P = 0.05) final BW, tended to increase (P = 0.06) average daily gain (ADG), and decreased (P = 0.05) hay intake (HI) compared with steers fed DDGS. There was a positive association (P ˂ 0.01) of crude protein intake with ADG and FBW. Dietary NRFC did not change (P ≥ 0.3) final BW, ADG, DMI, and HI. Protein source did not affect (P ≥ 0.16) hot carcass weight (HCW), longissimus muscle (LM) area, dressing, 12th rib fat thickness, or marbling score (MS). No differences were detected between NRFC for dressing, HCW, LM area, or MS (P ≥ 0.18); but diets with greater NRFC decreased (P = 0.03) the 12th rib fat thickness. Steers in the SHF treatment presented the lesser kidney-pelvic-heart fat compared with the remaining treatments (PS×NRFC interaction, P = 0.04). Soybean meal inclusion/increase in protein intake improved growth performance of feedlot steers compared with DDGS, despite protein intake meet the protein requirement. Increasing the NRFC did not affect growth or HI but decreased feed efficiency of steers fed DDGS.

Abstract Conflicting anecdotal accounts from producers about their cattle performance and fly-repellence outcomes while receiving garlic-infused supplements have limited feeding decisions. This study evaluated differences in animal performance and insectifugal outcomes among four groups (26 steers per group) over two years (total = 208 steers). The steers either received non-garlic mineral supplement (MS), MS+0.3% garlic oil-based premix (GOil), MS+2.5% garlic powder (LGP), or MS+5% garlic powder (HGP). A completely randomized design was implemented where each steer was assigned to each treatment group while balancing for bodyweight and breed composition. Steers received a feedlot ration and free-choice mineral supplement for 86 and 108 d in the first and second year, respectively. Individual feed and supplement consumption were measured with automatic feeding units. Fly abundance on each animal was determined using digital images collected during weekly fly surveys. The ADG, feed efficiency, ultrasound body composition, and intake-related activities were also evaluated during the study. Data were analyzed using linear- or generalized linear mixed models in SAS. A significant year and Group×year interactions were observed for daily supplement intake (P < 0.02). Similar interactions (P < 0.04) were observed for feeding behaviors associated with supplement intake. Fly abundance during the peak months was below the economic threshold and was not different among the groups (P = 0.25), but the year and Group×year interactions were significant (P < 0.02). There were no differences among the groups for DMI (P = 0.81), ADG (P = 0.54) and gain to feed ratio (P = 0.34). The Group×year interactions were present for the change in ultrasound rib-fat-thickness. The reasons behind the differences in supplement intake are not clear but may be related to the garlic products’ phytochemical profiles. These results suggest that further studies are required to identify the specific bioactive compounds in garlic that affect supplement intake.

This study was conducted to evaluate the effect of phosphorus (P) supplementation, with or without addition of other minerals, ionophore and antibiotic, on performance, P utilisation and profitability in finishing Nellore bulls in a feedlot. Forty-two animals, with an initial bodyweight of 296 ± 25 kg, were distributed in a completely randomised design consisting of three treatments and 14 replicates. The treatments were without P supplementation (T1), commercial mineral supplement specific for feedlot cattle (T2) and supplementation with dicalcium phosphate (T3). The T3 was formulated to achieve a P concentration similar to that of T2, but without adding other additives (e.g. vitamins, ionophores, yeast and chelates) in the mineral mix. The P concentrations were 2.4, 4.2 or 5.0 g P/kg of dry matter (DM), respectively, for T1, T2 and T3. The diet, on a DM basis, comprised sugarcane bagasse (200 g/kg) plus concentrate (800 g/kg). The DM, crude protein and neutral detergent fibre intakes and apparent DM digestibility were similar among the three treatments (P > 0.05). Despite the numerical difference on P concentration in T2 and T3 treatments, P intakes were similar in these treatments. The addition of commercial mineral supplement specific for feedlot cattle or dicalcium phosphate in diets increased P excretion in the faeces and urine, increased P retention and reduced the profitability of the feedlot. Performance and carcass traits were not affected by diet P concentrations (P > 0.05). The profit per head in T1 treatment was US$13.7 and the addition of the dicalcium phosphate and mineral mix in T2 and T3 did not result in profit, these treatments gave economic losses of US$6.80 and US$6.20 per head, respectively. Under Brazilian conditions, feedlot Nellore cattle fed high-grain diets do not require any additional mineral supplements. P concentration of 2.4 g/kg DM, as used in the control diet, was adequate to ensure animal performance and reduce faecal P excretion, which is in agreement with NRC and CSIRO recommendations. Lower values may also be appropriate, but were not tested here.

Nutritional Muscular Dystrophy

Nutritional muscular dystrophy (NMD) was prevented in suckling beef calves and lambs by the inclusion of selenium (14.8 ppm) and vitamin E (2,700 IU/kg) in the mineral supplement of their selenium-deficient dams. The fortified mineral supplement was provided for the latter two-thirds of gestation and for the 1st mo of lactation. Three to four mo after withdrawal of selenium supplementation, selenium levels in the cow and ewe milk, and in the kidney, liver, muscle and blood of the calves, ewes and lambs were comparable to published values for selenium-deficient animals. During the selenium supplementation period, the blood and milk selenium concentrations of the cows and ewes, and blood selenium levels of their offspring were well within normal ranges for animals raised in Canada and other countries. Thus, the method was effective against dystrophy and there was no evidence that it resulted in any abnormal selenium residues. The use of selenium plus vitamin E in mineral supplements is an economical, convenient and practical method for preventing NMD in ruminants. Its general use in Canada on a veterinary prescription basis, as required, appears indicated, pending clearance for the addition of selenium to ruminant supplements and rations.
