Testicular Parameters and Sperm Morphology of Chinchilla Rabbit Fed With Different Planes of Soymeal International Journal of Morphology
Oyeyemi,Matthew Olugbenga; Okediran,Babatunde Samuel.
The testicular parameters and sperm morphology were studied in twenty healthy Chinchilla breed bucks of rabbits fed with different planes of soybean meal. Their ages were between 6 to 10 months with their weights ranging from 1.4 to 1.9kg.The same quality of feeds was fed to each group throughout the study and at the rate of 0.5kg/head/day. The feeds contained graded percentage of soybean meal and growers mash. Semen used in this study was from the caudal epididymides while morphological aberrations were determined from a total count of 400 spermatozoa in smears obtained with Wells and Awa stain. Results of the spermiogram showed that the colour and consistency of the semen appreciated as the percentage of soybean meal increased. Group D with 90% soybean...

Poder de mercado das exportações de farelo de soja: uma análise via demanda residual AgEcon
Coronel, Daniel Arruda; Amorim, Airton Lopes; Braga, Marcelo Jose; Campos, Antonio Carvalho.
The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports
