Development of a NCR-42 Vitamin-Trace Mineral Mix
University of Nebraska 2005 Swine Day Report. A vitamin-trace mineral mix (NCR-42 VTMM) and a vitamin B-safety pak (biotin, choline, folacin, thiamin and vitamin B6) were formulated as possible common sources of nutrients for cooperative projects for the NCR-42 (North Central Regional) committee on swine nutrition. The adequacy of the NCR-42 VTMM and the vitamin B-safety pak were evaluated in a four-week growth trial with weanling pigs. The pigs (weaned 18-23d) were fed one of six diets: 1) NC, negative control, a common nursery diet with vitamins at minimum levels (VTMM OX); 2) treatment 1, a common nursery diet with VTMM vitamins at 100% of NRC 1998 requirements for 5 to 45 lb pigs; 3) treatment 2, a common nursery diet with VTMM vitamins at 300% of NRC 1998 requirements for 5 to 45 lb pigs; 4) treatment 3, a common nursery diet with VTMM vitamins at 100% of NRC 1998 requirements for 5 to 45 lb pigs and B-safety pak at 100% of NRC 1998 requirements for 5 to 45 lb pigs; 5) treatment 4, a common nursery diet with VTMM vitamins at 300% and B-safety pak at 300% of NRC 1998 requirements for 5 to 45 lb pigs; 6) UNL, a common nursery diet with the concentration of vitamins/minerals regularly fed in University of Nebraska (UNL) diets. Overall, there were no differences (P > 0.10) in average daily gain (ADG), average daily feed intake (ADFI), or feed efficiency (ADG/ADFI). However, numerically, there were increases in ADG and ADFI as the concentrations of minerals and vitamins increased. Pigs receiving the diet conforming to the typical University of Nebraska supplement had increased ADG, ADFI and feed efficiency compared to the negative control. Results from this study will be collectively examined with identical studies conducted at other research stations.
