Abstract Historic data supports the use of pre-weaning implants to maximize beef calf weaning weight, but their use has declined over the recent decade. A total of 96 beef steers (initially 85.2 kg BW and > 45 d of age) were used in a 168-d study to evaluate the effects of Synovex C® implantation during suckling on pre-weaning calf growth performance. At initial processing, calves were individually weighed and allotted in a completely randomized design to one of two treatments: 1) not implanted (control) or 2) implanted with 150 mg of trenbolone acetate and 21 mg of estradiol benzoate (SYNOVEX® ONE GRASS, Zoetis, Kalamazoo, MI). All calves were weighed on d 0 (implantation), 83, 126 and 168 (weaning), with ADG calculated for each period. Data were analyzed using the GLIMMIX procedure of SAS (v9.4, Cary, NC). There were 48 replicates per treatment, with grazing location as a random effect. While there were no detected differences in BW during the initial phases (P > 0.10), implanted calves tended to have greater (P = 0.100) greater weaning weight than non-implanted calves (279 vs. 265 kg, respectively). Calves implanted with SYNOVEX® ONE GRASS had 0.8, 0.12, and 0.16 kg/d greater (P < 0.05) ADG than those that were not implanted in all three phases. This resulted in an average of 0.10 kg/d greater (P = 0.002) ADG in implanted calves overall compared to the control. In conclusion, this research showed significant increases in suckling calf ADG in implanted calves compared to their non-implanted counterparts, which led to a tendency for 14-kg greater weaning weights. Additional research is warranted to consider the post-weaning growth and impact of re-implanting, but this data reinforces previous literature that suckling calf implantation continues to be cost effective for cow-calf producers.

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 > 0.10) across all treatments (42.4 ± 2.2 kg). Calves fed 22AA MR demonstrated greater (P < 0.05) BW compared with calves fed the 24 MR, and calves fed the 20 and 22 MR being intermediate and similar (P > 0.10; 78.7, 78.8, 76.5, and 81.8 kg for 20, 22, 24, and 22AA, respectively). CS intake was greater (P < 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 > 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 Our previous work has indicated that feeding a blend of essential oils and a proprietary cobalt source (EOC) in combination with monensin (MON) may not be mutually beneficial to dairy calf growth performance. To evaluate this observation further, a 240 d long-term growth experiment was conducted using 12 young growing Holstein bulls using a 2 × 2 factorial treatment arrangement. Main factors were EOC (Rum-A-Fresh, Ralco, Inc., Marshall, MN) and monensin (MON; Norvikon Biotechnology Co., Hunan, China) arranged in 4 treatments: 1) Control: ration fed without EOC or MON; 2) EOC: EOC fed at 26 mg/kg DM; 3) MON: MON fed at 25 mg/kg DM; and 4) EOC+MON: EOC and MON fed in combination. Holstein bulls were 70 d of age and similar in BW (93.3 ± 4.54 kg) and individually fed for 280 d. Body weights, frame measurements, and blood samples were collected monthly. Interactions of EOC by MON were detected for BW, BW gain, ADG, and a trend for feed conversion. Bulls fed EOC or MON demonstrated greater final BW (367.7, 385.2, 381.2, and 357.5 kg for Control, EOC, MON, and EOC+MON, respectively), while BW gains (277.2, 291.5, 284.8, and 265.2 kg) and ADG (1.16, 1.22, 1.19, 1.11 kg/d) were greatest for bulls fed EOC or MON compared with bulls fed EOC+MON, with bulls fed Control being intermediate and similar to bulls fed MON. Intake of DM was greater for bulls fed EOC (6.55, 6.99, 6.60, and 6.42 kg/d) compared with bulls fed remaining treatments. Feeding EOC or MON separately can improve growth performance of growing Holstein bulls. Why the combination of EOC and MON is antagonistic to growth performance of Holstein bulls is unknown.

Abstract Background: Maternal nutrition during gestation affects fetal development, which has long-term programming effects on offspring postnatal growth performance. With a critical role in protein and lipid metabolism, essential fatty acids can influence the development of muscle and adipose tissue. The experiment investigated the effects of late gestation supplements (77 d prepartum), either rich in saturated and monounsaturated fatty acids (CON; 155 g/cow/d EnerGII) or polyunsaturated fatty acids (PUFA; 80 g/cow/d Strata and 80 g/cow/d Prequel), on cow performance and subsequent calf growth performance as well as mRNA expression in longissimus muscle (LM) and subcutaneous adipose tissue at birth and weaning.Results: There was no difference (P ≥ 0.34) in cow body weight (BW) or body condition score from pre-supplementation through weaning. Relative concentrations of C18:3n-3 and C20:4n-6 decreased (P ≤ 0.05) to a greater extent from mid-supplementation to calving for PUFA compared to CON cows. Cow plasma C20:0, C20:5n-3, and C22:6n-3 were increased (P ≤ 0.01) in PUFA during supplementation period. At birth, PUFA steers had greater (P = 0.01) plasma C20:5n-3. No differences (P ≥ 0.33) were detected in steer birth BW or dam milk production, however, CON steers tended (P = 0.06) to have greater pre-weaning average daily gain and had greater (P = 0.05) weaning BW compared to PUFA. For mRNA expression in steers: MYH7 and C/EBPβ in LM increased (P ≤ 0.04) to a greater extent from birth to weaning for PUFA compared to CON; MYF5 in LM and C/EBPβ in adipose tissue tended (P ≤ 0.08) to decrease more from birth to weaning for CON compared to PUFA; SCD in PUFA adipose tissue tended (P = 0.08) to decrease to a greater extent from birth to weaning than CON. In addition, maternal PUFA supplementation tended (P = 0.08) to decrease MYOG mRNA expression in LM and decreased (P = 0.02) ZFP423 in adipose tissue during the pre-weaning stage.Conclusions: Late gestation PUFA supplementation decreased pre-weaning growth performance of the subsequent steer progeny compared to CON supplementation, which could have been a result of downregulated mRNA expression of myogenic genes during pre-weaning period.

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.
