| Optimal crop and livestock mix was determined for a representative Alabama farm using a dynamic programming model. Results indicate that decisions concerning livestock production are highly influenced by the amount of cotton base available on the farm. In most cases, increasing cotton base results in less cattle production. The triple base provisions of the 1990 Farm Bill, however, may give some cotton farmers an incentive to produce more stocker cattle during the winter months. Research results also indicate that the availability of farm programs can alter the optimal enterprise mix on a farm with no beginning base in cotton. |

| Questions have been raised regarding the economic costs of food-and-mouth disease (FMD) outbreak in the United States. This analysis examines how welfare changes are measured and argues that they must be decomposed by groups. Producers with animals quarantined and slaughtered because of FMD measure their welfare change using lost sales. Producers not quarantined measure their welfare change using producer surplus. The change in national sales revenue is accurate when the supply elasticity is low. Welfare changes for consumers also must be decomposed because the change in aggregate consumer surplus hides important shifts in welfare among groups of consumers. |

| This Working Paper presents a framework for assessing the impact of livestock diseases on the household economy and at local level. The framework is designed to help decision and policy makers in their selection of pro-poor livestock interventions. It should also help to protect them from making decisions under unwanted pressure from strong, non-objective political voices. The immediate users of the assessment methods presented in the Working Paper are expected to be consultants who have to evaluate interventions on behalf of their clients. These clients may be multi and bi lateral donors and, possibly, NGOs. Other users of the output could be governments receiving aid and communities receiving support. The author has drawn upon past experience to... |

| ABSTRACT Several spectral indices have been used to estimate droughts, however, these indicators only give evidence of a dry spell leaving out its impacts on significant economic activities performed in a given region. In this context, livestock breeding in one of the most important activities to analyze in the Brazilian semiarid region. The aim of this study was to evaluate the relationship between the drought indices, obtained through remote sensory devices, and annual milk production (2004 – 2014), identifying the most affected cities by the drought and were considered the most vulnerable and in need of special attention during dry periods. In order to analyze the data, the hierarchical grouping technique and correlation analyses between milk production... |

| Abstract: The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, in order to determine the relationships between forage grass nutritive quality and CH4 production. Guinea grass (Megathyrsus maximus), palisade grass (Urochloa brizantha), and signal grass (Urochloa decumbens) were evaluated. Palisade grass showed the highest organic matter, neutral detergent fiber, acid detergent fiber, lignin, and lower-crude protein content. Signal grass had the highest values for hemicellulose and neutral detergent fiber-nitrogen, and the lowest-cellulose content. Guinea grass and signal grass showed a higher-total gas production than palisade grass. Besides, Guinea grass... |
