Influence of eCG and breed on the number of oocytes collected and the production of in vitro embryos of young goats during the reproductive season.

The objective of this study was to determine the effect of breed and equine chorionic gonadotropin (eCG) on ovarian response and in vitro embryo production from young goats. Thirty-one (12 Alpine, 10 Nubian, and 9 Saanen) were randomly assigned into three treatments of eCG (T1, 0 IU; T2, 500 IU; and T3, 1000 IU). Alpine goats showed the highest amount and largest size of follicles (P = 0.

Dietary inclusion effects of phytochemicals as growth promoters in animal production.

Growth promoters have been widely used as a strategy to improve productivity, and great benefits have been observed throughout the meat production chain. However, the prohibition of growth promoters in several countries, as well as consumer rejection, has led industry and the academy to search for alternatives. For decades, the inclusion of phytochemicals in animal feed has been proposed as a replacement for traditional growth promoters.

Culturosity: Fostering Cultural Awareness Among Faculty and Residents in a Community Teaching Hospital.

Cultural awareness is the first step towards building cultural competence. 'he goal of our study was to evaluate the effect of a cultural awareness intervention among faculty and resi- dents in three residency programs at St. Vincent's Medical Center (SVMC).

Intraherd correlation coefficients and design effects for bovine viral diarrhoea, infectious bovine rhinotracheitis, leptospirosis and neosporosis in cow-calf system herds in North-eastern Mexico.

Knowledge of the intraherd correlation coefficient (ICC) and design (D) effect for infectious diseases could be of interest in sample size calculation and to provide the correct standard errors of prevalence estimates in cluster or two-stage samplings surveys. Information on 813 animals from 48 non-vaccinated cow-calf herds from North-eastern Mexico was used. The ICC for the bovine viral diarrhoea (BVD), infectious bovine rhinotracheitis (IBR), leptospirosis and neosporosis diseases were calculated using a Bayesian approach adjusting for the sensitivity and specificity of the diagnostic tests.

9a-hydr-oxy-3,4a,5-trimethyl-4a,6,7,8a,9,9a-hexa-hydro-4H,5H-naphtho[2,3-b]furan-2,8-dione), C(15)H(20)O(4), is a sesquiterpene lactone showing the typical eremophilanolide skeleton, which has been isolated from the plant Senecio candidans collected in the Chilean Magallanes region. The present study confirms the atomic connectivity assigned on the basis of (1)H and (13)C NMR spectroscopy, as well as the relative stereochemistry of the 4α-methyl,5α-methyl,8β-hydr-oxy,10β-H unit. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds involving the hydr-oxy group as donor and the oxo group as acceptor, giving chains along the a axis.

Bioactive eremophilanolides from Senecio poepigii.

A new bioactive eremophilanolide, 1alpha-tigloyloxy-8betaH,10betaH-eremophil-7(11)-en-8alpha,12-olide, was isolated from Senecio poepigii and its structure was elucidated by spectral analysis. 1alpha-Angeloyloxy-8beta-methoxy-10betaH-eremophil-7(11)-en-8alpha,12-olide was also isolated. Antifungal and insect antifeedant properties were evaluated.
