## Status:     

**Priority Rating:  High**
_**Issue:**_**  National Phenotypic/Genotypic Repository**
_**Explanation:**_**  Collection of existing phenotypic, genotypic, pedigree, and QTL data along with DNA, RNA, tissue samples will facilitate comprehensive data analysis. The repository would be publicly available. ARS coordinates activity due to long term commitment.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Paucity of Scientists with Quantitative Training**
_**Explanation:**_**  Expertise in quantitative genetics, statistics, and population genetics is in short supply. There is an aging faculty that represents a critical mass with this expertise. Training grants are urgently needed to meet the rapidly growing demand.**

## Status:     

**Priority Rating:  High**
_**Issue:**_**  Development of Statistical Analysis Techniques for Application to Genetic Evaluation**
- _**Explanation:**_**  Incorporation of genetic marker information into genetic evaluations is an urgent need. Research on statistical methodology to accommodate high-density SNPs is a major constraint to application of genomics research. Needs to be species neutral.**

## Status:     

**Priority Rating:  Medium**
_**Issue:**_**  Preservation of Unique Germplasm**
_**Explanation:**_**  There is need to maintain unique genetic lines in species where cryopreservation is not feasible. There was a conclusion that appropriately characterizing the problem is essential to gaining public support (e.g., relating to avian influenza).**

## Slide 12

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Alternative Feed Needs**
_**Explanation:**_**  Biofuel production is utilizing feedstuffs (corn, fats) commonly used as feedstuffs by livestock and poultry.  Alternative feedstuffs are needed.  This necessitates characterization of composition and nutrient availability.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Associative Effects Among Nutrients**
_**Explanation:**_**  The impact of associative effects among nutrients or feeds on feed utilization is not characterized so we can predict outcomes from different diets.  Need to understand mechanism and effects across gut compartments. **

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Nutrient x Genetic Interaction (multiple species)**
_**Explanation:**_**  Do different genetic lines utilize nutrients differently?  Different requirements?  Impact of nutrition on gene expression, "programming"?**

## Status:     

**Priority Rating:  Low**
_**Issue:**_**  Systems evaluation for impact of byproducts**
_**Explanation:**_**  Utilization of feedstuffs for biofuels appears likely to have an impact on diet formulation, farm profitability, nutrient management, product salability and societal concerns.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Improvement of Forage **
_**Explanation:**_**  There is a need to improve fiber digestibility to improve nutrient utilization.  This may entail changing the plant, better understanding the role of rumen microbes and effects of the rest of the diet.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Anti-nutritional Factors in Feedstuffs**
_**Explanation:**_**  How do we detect and reduce anti-nutritional factors (e.g., mycotoxins, factors in endophyte infected tall fescue, soy) and understand their effects on nutrient utilization.  Do we have the appropriate tools to assess them?  **

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Impact of Microflora**
_**Explanation:**_**  What is the effect of gut microflora?  Ruminal, small intestine, hindgut?  Potential improvements through use of "probiotics", adjuvants or diet components?  **

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Metabolism Studies / Evaluation of Feedstuffs**
_**Explanation:**_**  We need to reassess/assess nutrient requirements of animals (different genetics than 30 yr ago).  Revision/evaluation of feed analysis methods for nutritional relevance is needed.  In vitro methods need to be tied to in vivo response.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Increase utilization and decrease losses**
_**Explanation:**_**  Further evaluation of nutrient (e.g., N, P) inclusion in diets to reduce nutrient excretion.**

## Slide 22

## Status:  Needs to be investigated further

**Priority Rating:  High**
_**Issue:**_**  Limited ability to define and assess well being and stress of animals under production in pasture based systems**
_**Explanation:**_**  Limited data concerning the well being of animals in pasture based production systems exist. **
**Agreement on defining well being & limited methods for assessing animal stress constrain researchers from developing protocols for reducing this stress.**

## Status:  New and needs to be investigated

**Priority Rating:  Medium**
_**Issue:**_**  Limited empirical data concerning how utilization of grazing systems affect productive longevity of animals.**
_**Explanation:**_**  There is the assumption that animals completing their production cycles in extensive systems have increased productive longevity versus those in intensive systems of production.**

## Status:     

**Priority Rating:  N/A**
_**Issue:**_**  Limited information on combining nontraditional and conventional management systems to increase resource utilization.**
_**Explanation:**_**  Combient Modeling**
**Example:  Conventional concentrated dry lot dairy with maxed nutrient credits might consider moving certain aspects of operation to pasture based systems (e.g., dry cows, cows with mastitis, heifers).**

## Status:  Needs to be investigated further

**Priority Rating:  Medium**
_**Issue:**_**  There is limited empirical data quantifying the potential synergistic benefits of integrated grazing systems utilizing multiple forage-animal species.**
_**Explanation:**_**  Empirical data exists concerning the benefits of these systems under limited situations. **
**Synergistic benefits of these systems are still not well defined, thereby limiting development of management protocols to fully capture all resource inputs.**

## Status:  Needs to be investigated further

**Priority Rating:  High**
_**Issue:**_**  Consistent product delivery from pasture finished meat animals suffers from a lack of predictability of input (e.g., forages) quantities & qualities.**
_**Explanation:**_**  Year round delivery of quality meat products from pasture finished meat animals requires improved understanding seasonal forage quality fluctuation & G*E interaction impacts on product quality & quantity.**

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Lack of data concerning how to switch from conventional farming to organic farming while maintaining economic viability.**
_**Explanation:**_**  Farmers considering a transition to organic farming need information to guide them in making appropriate decisions during the transition to ensure sustainability of the new operation.**

_**Issue:**_**  Optimum supplementation of grazing dairy animals (includes: cattle, goats, sheep)**
_**Explanation:**_**       **

## Status:  New and needs to be investigated

**Priority Rating:  High**
_**Issue:**_**  Limited empirical data concerning effects of forage-based management and environment on equine health & production.**
_**Explanation:**_**  Horses are effected by many of the same issues affecting other grazing species (e.g., fescue toxicosis, salmonella, reproductive efficiency, etc.).  However, horses have not routinely been recognized by ARS or other agencies for research funding.**

## Status:  New and needs to be investigated

**Priority Rating:  Medium**
_**Issue:**_**  Limited empirical data effects of forage-based management and environment on grazing monogastric animal (e.g., chickens, pigs) health and production.**
_**Explanation:**_**  Much of the information available for grazing ruminant animals does not exist for these animals which are filling a niche market.  Thus, development of sustainable production systems for these animals on pasture is particularly difficult.**

## Status:

**Priority Rating:     **
_**Issue:**_**  How do we retain for the producer the value added to niche products?**
_**Explanation:**_**  This was not fully discussed.  May not be a researchable issue - but rather a marketing issue.**
