A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products AgEcon
Uri, Noel D.; Hyberg, Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

CROSS-HEDGING COTTONSEED MEAL AgEcon
Rahman, Shaikh Mahfuzur; Turner, Steven C.; Costa, Ecio de Farias.
This study examines the feasibility of cross-hedging cottonseed meal with soybean meal futures. A simple linear regression of cottonseed meal cash prices on soybean meal futures provides a direct price movement relationship. Using the estimated hedge ratios, the net realized prices are calculated for seven different cash markets. The net realized prices are higher than cash prices in three of the four years evaluated. The empirical analyses suggest soybean meal futures can be used as a potential cross-hedging vehicle for cash cottonseed meal.

Longo,FA; Menten,JFM; Pedroso,AA; Figueiredo,AN; Racanicci,AMC; Gaiotto,JB; Sorbara,JOB.
There are some evidences described in the literature showing reduced energy metabolizability of ingredients for newly hatched chicks. Hence, a metabolism trial was carried out with the objective of determining the metabolizable energy of corn grain, soybean meal and micronized full fat soybean for newly hatched chicks. The method of total excreta collection was used in an experiment with 192 male chicks from one to seven days, distributed in a completely randomized design with four treatments and four replicates of twelve birds. Excreta were collected from four to seven days of age. The treatments included a reference diet, two test-diets consisting of 60% of the reference diet and 40% of the test ingredients: corn grain (CG) and soybean meal (SM), and one...

Soccol,Carlos Ricardo; Pollom,Teresinha E. V.; Fendrich,Ricardo Cancio; Prochmann,Fernando Alberto; Mohan,Radijiskumar; Blaskowski,Marita Maciel Moreira; Melo,André Luiz de Almeida; Carvalho,Cláudio Jose Barros de; Soccol,Vanete Thomaz.
Aedes aegypti is the vector of Dengue disease, responsible for 20,000 deaths/year worldwide. Bacillus thuringiensis var israelensis - Bti releases selective and effective toxins (crystal proteins) against A. aegypti larvae. We present a low cost bioprocess for toxin production, accomplished by a selected Brazilian strain Bti (BR-LPB01) and employment of low cost substrates. Soybean meal and sugarcane molasses lead to high toxic effectiveness after 2L bioreactor fermentation (LD50=26ng/mL), near to the reference strain IPS82 (LD50=17.3 ng/mL). The pH ranged between 5.8 and 7.0 during the exponential growth period and between 7.0 and 8.4 during the stationary phase, with low activity. Thus, control of foam and pH 7.0 were started and proved to be crucial for...

Imaizumi,Hugo; Santos,Flávio Augusto Portela; Bittar,Carla Maris Machado; Correia,Paulo Sérgio; Martinez,Júnio César.
Feeding extra protein as an attempt to increase amino acid flux to the intestine may increase lactational performance of dairy cattle. The objective of this study was to compare lactating dairy cow diets containing 16% crude protein (CP), adequate in rumen degradable protein (RDP) and metabolizable protein (MP) according to NRC (2001), with diets containing 17.5% CP. Forty-two Holstein cows (27 primiparous and 15 multiparous, with 172 days in milk) were used in a 3 ´ 3 Latin Square design with 14 replicates. Control diet consisted of 16% CP, adequate in RDP and MP . Crude protein content of diets was increased to 17.5% by feeding extra soybean meal and cottonseed meal (SBCS17.5) to increase diet MP, or extra urea (U-17.5) to increase diet RDP. The...
