In determining the economic impact of a possible outbreak of the quarantinable wheat disease Karnal Bunt, an examination was made of the detailed components of the costs involved. The costs were classified as: (a) Direct costs (yield and quality losses); (b) Reaction costs (export bans, quality down-grading, seed industry costs); and (c) Control costs (quarantine zones, fungicides, spore destruction). The relative importance of each of these cost components is measured for a hypothetical outbreak of Karnal Bunt in the European Union, as a means of ensuring that the policy responses to such an outbreak are appropriate considering the costs involved.

Measuring the Stochastic Monetary Benefits of Multiple Inlet Irrigation in Arkansas Rice Production

Watkins, K. Bradley; Hristovska, Tatjana; Anders, Merle M..

Irrigation fuel costs represent a significant portion of rice production expenses. Multiple inlet (MI) irrigation represents a water saving alternative to conventional flood irrigation. This study uses simulation to calculate the range of monetary benefits to MI in rice production. Water savings from MI relative to conventional flood irrigation along with rice yields, rice prices, and prices for key production inputs (diesel and fertilizer) are simulated, and stochastic rice net returns above variable and fixed expenses are calculated for different pump lifts with and without MI. Monetary benefits to MI are measured as the difference in net returns with and without MI. The results indicate MI monetary benefits depend greatly on pump lift and the presence...

RISK AND SITE FACTORS AFFECTING POTENTIAL NITROGEN DELIVERY IN THE VIRGINIA COASTAL PLAIN

Peng, Wei; Bosch, Darrell J..

The effects of cropland slope, distance to surface water, farmers' risk attitudes, and farmers' nitrogen (N) fertilizer applications on potential N delivery to streams and costs of reducing N delivery were evaluated for a representative Virginia peanut-cotton farm. Target MOTAD and generalized stochastic dominance were used to select preferred plans for different levels of risk aversion. Costs of reducing N delivery were lower on farms where fields were located close to surface water, where N was overapplied relative to extension fertilizer recommendations, and where the operator was risk averse. Cropland slope had less effect on cost of reducing N delivery relative to other factors.

Modeling Economywide versus Sectoral Climate Policies Using Combined Aggregate-Sectoral Models

Pizer, William A.; Burtraw, Dallas; Harrington, Winston; Newell, Richard G.; Sanchirico, James N..

Economic analyses of climate change policies frequently focus on reductions of energy-related carbon dioxide emissions via market-based, economywide policies. The current course of environment and energy policy debate in the United States, however, suggests an alternative outcome: inefficiently designed and/or sector-based policies. This paper uses a collection of specialized, sector-based models in conjunction with a computable general equilibrium model of the economy to examine and compare these policies at an aggregate level. We examine the relative cost of different policies designed to achieve the same quantity of emissions reductions. We find that excluding a limited number of sectors from an economywide policy does not significantly raise costs....

Hybrid Phytase and Carbohydrases in Corn and Soybean Meal-Based Diets for Broiler Chickens: Performance and Production Costs

Rev. Bras. Ciênc. Avic.

Bavaresco,C; Krabbe,E; Gopinger,E; Sandi,AJ; Martinez,FN; Wernik,B; Roll,VFB.

ABSTRACT This study aimed to evaluate the effect of using 500 FTU/kg of hybrid phytase (created from three bacteria - Natuphos E), with or without xylanase and glucanase (560 TXU/kg; 250 TGU/kg) - Natugrain TS, in corn and soybean meal-based diets, with nutritional reductions in metabolizable energy (ME), Ca, and available phosphorus (AP), on performance parameters and production costs in broiler chickens. The 1875chickens were housed in boxes and distributed among 5 treatments with 15 replicates of 25 chickens each. The experiment included a positive control (the diet of which met the nutritional requirements of the birds), two negative controls (with ME reductions of 70 and 100 kcal/kg, and fixed reductions in Ca [0.16%] and AP [0.15%]), and two...

In the present study, 35 farmers contracted by an integration company were selected. Each farmer owned an average of seven poultry houses, and housed six flocks per year, with a total of 4.0 million housed broilers. Birds were grouped into 5 market ages (MA1=<43, 43<MA2=<44, 44<MA3=<45, 45<MA4=<46, MA5>46 days), and the following parameters were measured: average flock body weight (AFW), feed conversion ratio (FCR), livability (L), production efficiency index (PEI), production cost, and farmer's gross margin. MA significantly influenced all parameters, except production cost/kg broiler. The effects of farm and farm*MA interaction were not significant. Each day of MA increase resulted in increases of 68.43g and 0.039 units in AFW and...

The objective of this study was to evaluate the effects of feeding cattle with isoprotein and isoenergetic diets, with and without the addition of polyclonal antibody preparation (PAP), yeasts (YST) or monensin sodium (MON) on performance, carcass characteristics and gain cost in feedlot. Ninety-five 20-month old bullocks (323.3±21.8 kg) were distributed in 25 pens. The completely randomized experimental design had a 2 × 2 + 1 factorial arrangement and the treatments were replicated 5 times. There was no effect of MON for DMI throughout the feedlot period; however, MON reduced the dry matter intake (DMI) in g/kg of BW in the first 28 days when compared with the other treatments. The gain cost decreased with MON addition in relation to the other treatments....

ABSTRACT The objective of this study was to evaluate residual feed intake (RFI), residual intake and body weight gain (RIG) and their relationship with other traits of efficiency, performance, and economic analysis of sheep. Lambs (n = 102) were evaluated during 56 days and a herd consisting of 500 ewes was simulated with the mean of dry matter intake (DMI) and final body weight of the lambs, the same as that of the experimental lambs. The lambs were fed hay-based diet of Tifton 85 (Cynodon spp.), corn, and soybean in the voluminous:concentrate ratio of 35:65. Residual feed intake and RIG were correlated with DMI, feed conversion ratio, and feed efficiency. Residual intake and body weight gain were positively correlated with average daily gain, relative...

ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity (38% dry matter, DM). Plants were chopped approximately 2 cm after harvest and then treated with inoculants and were ensiled in 1.5-L mini laboratory silos. Two lactic acid bacterial inoculants with enzymes (LAB+enzymes I: Pediococcus acidilactici, Lactobacillus plantarum, and Streptococcus faecium with cellulase, hemicellulase, pentosanase, and amylase; LAB+enzyme II: P. acidilactici, L. plantarum,...

Rice production potential zoning of Petchaburi province had been conducted from 2010 to 2012. Research methodology composted of general rice production information collection, soil sampling and crop cutting from farmer field, and field experiment. The research found that there were 4 major rice varieties growing in the area Chainat1, Phitsanulok2, Suphanburi60 and Suphanburi1. The field experiments for comparing of fertilizer application were conducted 2 seasons at 12 locations. The results showed that L1 area, recommended fertilizer application (F1) gave the average yield of 1,067 kg/rai, while fertilizer application base on soil analysis (F2) gave the average yield of 1,222 kg/rai. Farmers’ practice of fertilizer application (F3) gave the average yield...

Luempua is a dark-purple glutinous upland rice belongs to the Mong hilltribe. The origin prior to the time of seed purification was the mountainous area 450 m above sea level. The variety is normally grown in the wet season under upland condition. To obtain the information for appropriate time of sowing and growing with water as for the lowland sowing, Luempua was sown by transplanting in the cement container every 15 days from 2010-2013 at Phitsanulok Rice Research center (PSL). Results revealed that the most appropriate time of sowing is from mid to the end of May and the lowland areas especially those prone to Brown planthopper infestation are not recommended. Seed conservation was carried out at 3 sites i.e. upland farmer’s field, amphoe Khao Kor,...
