2 3/23/ How does Vita Plus evaluate new products and nutritional concepts? Actively involved in key scientific meetings Continuously evaluate peer reviewed research Meet with vendors Build network of key contacts inside and outside swine industry Collaborate with key players (Universities and suppliers) Evaluate external research trials Conduct our own research Background Continuous advancements in the genetics of modern pigs have resulted in superior growth performance and protein accretion, and potentially altering dietary nutrient. For growing-finishing pigs, providing optimum dietary Lys is crucial for maximum lean growth and optimizing feed cost. Although considerable research has been conducted to determine the optimum Lys requirement for swine, there are limited data reporting the Lys requirements at heavier market weights. 2

4 3/23/ Feeding optimal SID Lysine levels The dietary SID Lysine levels on the previous slides were optimal under the conditions of the study You can use mentor growth modeling to determine optimal dietary SID Lysine levels to feed to YOUR pigs. Dietary energy Feed accounts for up to 75% of pork production cost, with energy alone representing 50% or more of the total cost. Thus, the first and most important step in diet formulation is to set the energy concentration. To set the optimal energy level in the diet, we must know how an incremental change in dietary energy affects factors such as: diet cost, growth (ADG, G:F), and carcass traits (yield, lean). Even though energy is the most expensive component of the diet, the level used in formulation is often based on history or impact on diet cost rather than an indepth analysis to determine the most economical level. 4

6 3/23/ Impact of increasing NDF on carcass yield Coble et al. (2015). Measuring the impact of NDF on carcass yield Yield, % = WP (d) NDF1 (%) NDF2 (%) (NDF2 (%) WP (d)) Data from 8 trials were used to develop the model. NDF1 (%) = NDF concentration in dietary phase before final dietary phase. NDF2 (%) = NDF concentration in final dietary phase before marketing. WP (d) = Withdrawal period. 6

7 Net energy, Kcal/kg 3/23/ Application of the model Scenario i. Six phase feeding program. ii. Corn-soybean meal-ddgs based diets. iii. User specified had an inclusion of 20% DDGS, with an average NE equal to 1,132 kcal/lb and 13% NDF, across dietary phases. iv. To create the NE range diets were formulated to contain 0 and 40% DDGS. v. Corn $3.35/bu, Soybean meal $/ton, DDGS $/ton, L-Lys $0.79/lb. Dynamic scenario variables definition i. Carcass pricing modified from lower-priced ($0.40/lb) to high-priced ($0.90/lb). ii. Economic evaluation based on carcass and fixed time basis.

10 3/23/ Take home message 1. The dietary SID Lysine: Increasing levels of a nutrient in diet formulation will often produce a linear increase in diet cost; therefore, if the law of diminishing returns applies, formulating diets slightly below the requirement for some nutrients can potentially be more economical. 2. Dietary NE: is an important predictor of growth performance in growingfinishing pigs. The extent of the improvement in growth performance provided by dietary NE can be minimized if the amino acids or other nutrients are limiting. 3. NE economic model: The model developed can be utilized to predict the value of dietary NE that yields the most economical return to the production system.

Take-aways Although there is much still to be understood in vitamin and mineral nutrition, we are committed to evaluating external research and carrying out our own research to answer those questions that are relevant to producers, and their bottom line. 13

14 3/23/ What s Happening With Feed Additives? Dean Koehler Vita Plus Technical Services Manager In 2016 we were haunted by the looming specter of VFDs The swine industry has gotten used to VFDs We get a VFD if we need to use a medically important antimicrobial to treat disease in our pigs Antibiotic growth promotion using medically important antibiotics has ended 14

15 3/23/ No more Growth Promotion using: Chlortetracycline Lincomycin Neo-Terramycin Penicillin Virginiamycin (Stafac) Oxytetracycline Tylosin (Tylan) Remaining Growth Promoters: Antibiotic Growth Promoters Bacitracin zinc (Albac) BMD Bambermycins (Flavomycin) Carbadox (Mecadox) Ionophore Narasin (Skycis) Repartitioning Agent Ractopamine (Paylean, Engain) 15

16 3/23/ What is currently happening? There has been modest interest in the use of antibiotic replacement additives Acidifiers Antibody Products Bacteriostatic minerals (Cu, Zn) Botanicals Enzymes Essential Oils Organic Acids Prebiotics Probiotics Direct-fed Microbials Yeast Products Combination Products Where are we today? And what does the future hold? There are MANY classes of additives and A LOT of individual products Listing of Direct-Fed Products 16

17 3/23/ -specific additives: 113 Enzyme products 112 Yeast products 78 Bacterial products 30 Oligosaccharide products Not listed: Acidifiers, Botanicals, Essential Oils, Organic Acids How do we sort all this out? Evaluate the options Review scientifically valid data to screen options Conduct research on promising products or compounds Responses to many products are HIGHLY variable Agents act at the gut level Interact with the gut microbiome 17

18 3/23/ Gut microbes are important Gut microbiome (microbiota) lb human body consists of about 10 trillion cells lb human has about 100 trillion microorganisms in their intestines The same is true of a lb pig There are 10x more gut microorganisms than there are living cells in the host (pig or human)!!! What can pork producers do? Don t forget the feed additives that have already been proven that are still available CuSO4, TBCC, ZnO Chromium Superdose Phytase Sarsaponin Xylanase 18
