Bacterial Systems

In many bacterial systems chloramphenicol has been shown to inhibit protein synthesis (Hahn & Wisseman, 1951; Gale & Folkes, 1953). The precise mechanism of this inhibition is not clear, although the evidence suggests that the interaction of the soluble RNA-amino acid complex with the ribosomes is prevented because the attachment of the messenger RNA to the ribosomes is itself impaired (Lacks & Gros, 1959; Nathans & Lipman, 1961; Jardetsky & Julian, 1964; Julian & Jardetsky, 1964). In contrast to its effect on bacterial systems, chloramphenicol has been reported to have little or no action on the protein synthesis by cell-free extracts of mammalian cells (Rendi, 1959; Ehrenstein & Lipmann, 1961). A basis for this resistance has been proposed by Vazquez (1964), who finds that whereas bacterial ribosomes bind chloramphenicol, ribosomes from other organisms do not. Nevertheless, it cannot be stated with any confidence that chloramphenicol has no effect on the protein synthesis of animal cells.

Soluble Zinc

Abstract Previously, we reported that supplementing a water soluble zinc via drinking water (0 to 80 mg/L) to nursery pigs improved ADG and G:F. To evaluate the efficacy of higher titrated levels of this water soluble zinc amino acid complex (ProPath®Zn LQ, Zinpro Corporation, Eden Prairie, MN) on growth performance, 280 crossbred pigs (5.5 kg BW; 19 d of age) were randomly allotted to four water treatments (7 pens/treatment; 10 pigs/pen). The water treatments were 0, 40, 80 and 160 mg Zn/L of water. Pigs were fed in 4 dietary phases with complex, nutrient-dense, corn-soybean meal-based diets: Phase 1 and 2 (2,500 and 1,750 mg Zn as ZnO/kg; d 1–7 and 7–14, respectively) and Phase 3 and 4 (200 mg Cu as CuSO4/kg; d 14–23 and 23–42, respectively). Pigs and feeders were weighed weekly to determine ADG, ADFI, and G:F. Water meters were used to record and calculate water disappearance and zinc intake. Data were analyzed as a randomized complete block design. Orthogonal polynomial contrasts were used to determine linear and curvilinear effects. Water and total zinc intake increased linearly (P < 0.001) with increasing water zinc concentration. From d 0–14 when high dietary zinc was fed, there were no differences (P > 0.10) in ADG, ADFI, or G:F. However, from d 14–42 when basal levels of zinc were fed, quadratic improvements in ADG (0.545, 0.561, 0.578, 0.546 kg; P < 0.05) and G:F (0.686, 0.706, 0.723, 0.702; P < 0.01) were observed with increasing zinc via water. Similarly for d 0–42, ADG (0.435, 0.440, 0.454; 0.434 kg; P = 0.07), G:F (0.726, 0.740, 0.763, 0.749; P = 0.05) and average ending wt (23.73, 23.97, 24.55, 23.70 kg; P = 0.07) improved quadratically with increasing zinc. In conclusion, supplementing ProPath®Zn LQ via water resulted in improvements in ADG and G:F for nursery pigs.

Abstract A 42-d research study evaluated effects of feeding beef steers increasing levels of dietary Zn from Zn methionine (AAC-Zn; ZINPRO, Zinpro Corporation, Eden Prairie, MN) with or without supplemental Cu from Cu amino acid complex (AAC-Cu; Availa Cu, Zinpro Corp.) concurrently with ractopamine hydrochloride (RAC; Optaflexx, Elanco Animal Health, Greenfield, IN). One hundred-twenty steers (mean BW = 624 kg), ≤ 50 d from projected harvest were randomized to three pens (40 steers/pen) equipped with GrowSafe Systems (Calgary AB, Canada) feed bunk technology. Each pen was assigned to one of three treatment diets: 1) basal finishing diet + 30 mg Zn/kg DM from AAC-Zn (CON); 2) basal finishing diet + 90 mg Zn/kg DM from AAC-Zn (AAC-Zn90); or 3) AAC-Zn90 diet + 10 mg Cu/kg DM from AAC-Cu (AAC-Zn/Cu). Following allocation to treatments, cattle were acclimated to pen cohorts and GrowSafe feed bunks for 7 days. All steers were fed 300 mg RAC∙hd-1∙d-1 starting 35 d prior to harvest. Individual feed intake measurements began with RAC feeding and continued for 35 d until cattle were shipped for harvest. Carcass data were collected from each steer. Data were analyzed with individual animal as the experimental unit using PROC MIXED and PROC GLIMMIX procedures of SAS 9.4 (SAS Institute, Cary, NC). Numerically AAC-Zn90 fed cattle had heavier carcass weights than CON and AAC-Zn/Cu. Steers fed AAC-Zn90 had greater (P = 0.02) marbling scores compared to AAC-Zn/Cu. Steers fed AAC-Zn90 had lower backfat thickness (P = 0.02) and numerically greater marbling scores compared to CON. A biphasic program of feeding a lower level of AAC-Zn for the duration of the finishing phase followed by an increased rate of AAC-Zn during RAC feeding may optimize overall live and carcass response and improve total individual animal value.
