BACKGROUND Control of animal tuberculosis (TB) through vaccination has emerged as a long-term strategy to complement test and slaughter control strategy. A pilot trial under field conditions was conducted in a goat herd with high TB prevalence to assess the efficacy of the Mycobacterium bovis BCG vaccine. RESULTS Twenty-three goat kids vaccinated with BCG and other 22 unvaccinated control kid...

Goat production is an important economic activity for rural communities in the Gran Chaco of Argentina. Goat corrals are important for the survival of peridomestic populations of Triatoma infestans. This study evaluated the impact of modifying the traditional structure of goat corrals on T. infestans populations and goat productivity in the region of Los Llanos (La Rioja). Thirty-nine experimen...

Advances in mineral nutrition of goats have been made during the last decade, especially in our understanding of Ca and P requirements. However, few studies have focused on the mineral requirements of crossbred Boer goats in their growth phase. Our objective for this study was to determine the macromineral (Ca, P, Mg, K, and Na) requirements for the maintenance and growth of intact, male three-...

One hundred eighty-one Boer-sired goat kids from dams of predominantly Spanish breeding (17.6 ± 2.34 kg initial BW; 177 wethers, 4 doelings) were used to determine optimum inclusion level of concentrate in diets fed to goats in confinement. Effects of elevated loafing areas on performance were also examined. Goats were blocked by weight (2 blocks per treatment) and randomly assigned to 1 of 12 ...

To improve nutrient content of goat milk, we describe the construction of a vector (pBLAC) containing a hybrid goat β -lactoglobulin (BLG) promoter/cytomegalovirus (CMV) enhancer. We also describe the generation of transgenic goats expressing rhLA by somatic cell nuclear transfer (SCNT). Of 334 one-cell stage embryos derived from three transgenic cell lines and 99 embryos derived from non-trans...
