A 6 wk trial was conducted to evaluate the effects of nucleotide supplementation in improving performance, nutrient digestibility, and immune blood profiles so as to reduce foot-and-mouth disease (FMD) vaccine stress in growing pigs. A total of 120 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 25.76 ± 1.83 kg were used. Pigs were allocated to one of three treatments (eight pens per treatment; three barrows and two gilts per pen) based on BW and sex. Pigs were injected with FMD vaccine at 84 d of age (2 wk after experiment started). Dietary treatments consisted of (1) CON: corn–soybean-meal-based diet, (2) NUC1: CON + 0.5% nucleotide, and (3) NUC2: CON + 1.0% nucleotide. In the current study, the growth performance of gain:feed ratio (G:F), the apparent total tract digestibility of dry matter and nitrogen was linearly (P < 0.05) increased with the increasing level of nucleotide. After injection, the concentration of cortisol and epinephrine was decreased (P < 0.05) linearly in nucleotide treatments. In conclusion, nucleotide supplementation to FMD vaccinated pigs showed positive effects on improving performance, immune system health, and reducing vaccine stress in growing pigs.

Continuing studies on the physical and chemical properties of foot-and-mouth disease virus (FMDV) have included electron microscopy of RNA strands released when highly purified virus (1) was dialyzed against demlneralized distilled water. The RNA strands were dried on formvar-carbon coated electron microscope screens pretreated with 0.1% bovine plasma albumin in distilled water. At this low salt concentration the RNA strands were extended and were stained with 1% phosphotungstic acid. Random dispersions of strands were recorded on electron micrographs, enlarged to 30,000 or 40,000 X and the lengths measured with a map-measuring wheel. Figure 1 is a typical micrograph and Fig. 2 shows the distributions of strand lengths for the three major types of FMDV (A119 of 6/9/72; C3-Rezende of 1/5/73; and O1-Brugge of 8/24/73.

Models for the structure of foot-and-mouth disease virus (FMDV) have been proposed from chemical and physical measurements (Brown, et al., 1970; Talbot and Brown, 1972; Strohmaier and Adam, 1976) and from rotational image-enhancement electron microscopy (Breese, et al., 1965). In this report we examine the surface structure of FMDV particles by high resolution electron microscopy and compare it with that of particles in which the outermost capsid protein VP3 (ca. 30, 000 daltons) has been split into smaller segments, two of which VP3a and VP3b have molecular weights of about 15, 000 daltons (Bachrach, et al., 1975).Highly purified and concentrated type A12, strain 119 FMDV (5 mg/ml) was prepared as previously described (Bachrach, et al., 1964) and stored at 4°C in 0. 2 M KC1-0. 5 M potassium phosphate buffer at pH 7. 5. For electron microscopy, 1. 0 ml samples of purified virus and trypsin-treated virus were dialyzed at 4°C against 0. 2 M NH4OAC at pH 7. 3, deposited onto carbonized formvar-coated copper screens and stained with phosphotungstic acid, pH 7. 3.
