Maternal Supplementation

The objective of this study was to investigate effects of maternal supplementation with an injectable trace mineral (Cu, Mn, Zn, and Se) on subsequent steer performance during the finishing phase. Seventy-six Angus cross steers (initial body weight 249 ± 41.5 kg) from dams administered either an injectable trace mineral (TM; Multimin 90) or sterilized physiological saline (CON) during prepartum stage were used. Individual feed intake during the finishing phase were recorded with GrowSafe feed bunks. Blood and liver biopsy samples were collected to evaluate trace mineral status. Steers were slaughtered at 413 ± 26 days of age and carcass data were obtained at a commercial abattoir. Growth performance or mineral status of the steers during the finishing phase was not affected (p ≥ 0.14) by maternal treatments. Carcass characteristics were not different (p ≥ 0.18), except steers from TM dams had greater (p = 0.05) percentage of carcasses graded as Choice or greater. In conclusion, maternal supplementation of an injectable trace mineral increased the percentage of carcasses graded as Choice or greater, other than that, maternal supplementation had limited influence on finishing phase growth performance, trace mineral status, or carcass characteristics of the subsequent steer progeny.

Abstract Two experiments were conducted to determine the effects of trace mineral source and level for grow-finish pigs. In Exp. 1, 2,168 pigs (initial BW = 23.0 kg) were used in a 117-d trial. There were 5 treatments based on inorganic (sulfates and oxides) or organic (Alltech Bioplex, Lexington, KY) minerals supplemented at different levels as follows: 1) Industry inorganic (120 mg/kg Zn, 100 mg/kg Fe, 40 mg/kg Mn, 10 mg/kg Cu); 2) 100% NRC inorganic (60 mg/kg Zn, 60 mg/kg Fe, 2.2 mg/kg Mn, 4 mg/kg Cu); 3) 33% NRC organic (20 mg/kg Zn, 20 mg/kg Fe, 0.7 mg/kg Mn, 1.3 mg/kg Cu); 4) 66% NRC organic (40 mg/kg Zn, 40 mg/kg Fe, 1.5 mg/kg Mn, 2.6 mg/kg Cu); and 5) 100% NRC organic (60 mg/kg Zn, 60 mg/kg Fe, 2.2 mg/kg Mn, 4 mg/kg Cu). Selenium level was 0.30 mg/kg for all treatments. Treatment 1 had 14 replicates and the other treatments had 18 replicates. Pigs were weighed approximately every three weeks and carcass data was collected at the end of the trial. Data was analyzed with SAS MIXED procedure. There was no evidence for differences (P > 0.10) for overall ADG, ADFI, G:F, and final BW. Pigs fed 66% NRC organic had the highest (P < 0.05) percentage lean and loin depth. In Exp. 2, 1,188 pigs (initial BW = 25.9 kg) were used in a 120-d trial with two treatments: 1) Industry inorganic and 2) 66% NRC organic, with the same mineral levels as Exp. 1 and 24 replicates per treatment. There was no difference (P > 0.10) in growth performance. Similar to Exp. 1, pigs fed 66% NRC organic had higher (P < 0.05) percentage lean and loin depth. In conclusion, lower levels of organic trace minerals resulted in improved carcass characteristics without compromising growth performance.

Abstract The objective of this study was to determine if different sources and levels of supplemental copper (Cu), zinc (Zn), and manganese (Mn) affect growth performance, health and carcass characteristics of finishing beef steers. A large pen, commercial feedlot in OK utilized 1,707 crossbred steers (297 ± 5 kg) randomized across 8 pens/treatment. Supplemental trace mineral treatments consisted of: Control (CON) = CuSO4 plus Availa® Cu (10.6 ppm), ZnSO4 plus Availa Zn (37.8 ppm), and MnSO4 plus Availa Mn (25.5 ppm); Combination (COMBO) = basic Cu chloride (IntelliBond® C; 10 ppm), ZnSO4 plus Zn methionine (ZINPRO® 120; 90 ppm), and MnSO4 plus Mn hydroxychloride (IntelliBond M; 20 ppm); or Hydroxy (HYD) = basic Cu chloride (IntelliBond C; 10 ppm), Zn hydroxychloride (IntelliBond Z; 90 ppm), and MnSO4 plus Mn hydroxychloride (IntelliBond M; 20 ppm). Statistical analysis was performed using SAS with pen as the experimental unit and pre-planned orthogonal contrasts to separate means. Contrasts were: CON vs. COMBO and HYD (level) and COMBO vs. HYD (source). Supplemental trace mineral source or level did not affect final BW (P ≥ 0.34), ADG (P ≥ 0.36), DMI (P ≥ 0.36), feed efficiency (P ≥ 0.30), morbidity (P ≥ 0.28), total treatment days (P ≥ 0.43), or mortality (P ≥ 0.33) (Table 1). Additionally, trace mineral source or level did not affect HCW (P ≥ 0.78), DP (P ≥ 0.85), or backfat thickness (P ≥ 0.32) (Table 2). Increased level of trace mineral tended (P = 0.13) to increase marbling score. There was tendency for COMBO to have a larger loin muscle area (P = 0.14) and lower yield grade (P = 0.10) than HYD. Feeding a lower level of sulfates and amino acid complexes resulted in similar performance to higher trace mineral levels. Providing 100% Zn from Zn hydroxychloride resulted in an economic benefit while maintaining similar performance and carcass characteristics as feeding a combination of ZnSO4 and Zn methionine.
