Saanen male goats evaluated for body weight, scrotal circumference and volume, preputial release and semen characteristics from birth to 12 months old. At 3 months old, 77,4% of the animals had a complete preputial release and at 4 months all showed a released prepuce. Theres was no goat with spermatozoa in the ejaculate at the age of 3 months, although at 4 months 23.1% of them ejaculated live spermatozoa. At 7 months, mean sperm motility is 70.0 ± 12,9%, with a range of 55-90%. Testicular size increase just before live spermatozoa could be found in the ejaculate, and had a higher positive correlation with body weight (r=0,92) than with age (r=0,84). On the other hand, sperm motility had higher correlation with age (r=0,5526) than with body weight (r=0,45) or scrotal circumference (r=0,39). For Saanen goats under intensive management in tropical condition, the separation between male and female kids must be done at 3 months of age to avoid undesirable pregnancy. Saanen bucks can be allowed to beed at a moderate frequency at the age at of 7 monsths. Saanen bucks raised under the insensive management that is usual in Brazilian dairy goats farms, can be allowed to breed at teh age of seven months, although is recomended not to overuse the bucks until they reach a sperm output close to that of adult bucks. |

Death from hunger in the world may overcome the number of deaths in conventional war. Therefore, food should be considered a National Security core issue of any country. However, the concept of National Security has evolved in this direction only with the end of the Cold War and a growing public awareness that global changes may exacerbate tensions related to food and water shortages. Accordingly, this paper presents a conceptual evolution of the food issue within the context of National Security. Brazil?s situation is contrasted to international scenarios outlined in an attempt to earn greater attention from the Ministry of Defense regarding Brazilian agriculture due to its important role in the five expressions of national power. |
