Recent unenclosed iron-fertilization experiments in the equatorial Pacific Ocean have shown that phytoplankton biomass can be increased substantially by the addition of iron. Analyses of size-fractionated chlorophyll indicate that much of the increase during the most recent fertilization experiment, IronEx II, occurred in the .10-mm size fraction. We used flow cytometry, combined with taxon-spe...

The present study was undertaken to evaluate the accuracy of ultrasonography in early pregnancy diagnosis in goats. Ultrasonographic scanning with real time B-mode ultrasound machine having 5 MHz linear array transducer was performed on gravid uterus (n=24) obtained from slaughterhouse (Group I). Crown rump length (CRL) measured by ultrasound was found significantly different (p<0.05) with actu...

This study was accomplished with the objective to determine parameters of lactation curves in Beetal goats using Wood’s model. Therefore, milk yield data from 127 Beetal goats maintained at five different government farms were recorded from post-kidding to drying off of does. Wood model parameters were estimated using non-linear regression and individual curves were fitted. The characteristics/...

the objective of this study was to evaluate genetic and phenotypic parameters for some reproductive traits of black bengal does. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanent environmental effects. the least-squares means of litter size at birth (lsb), litter size at weaning (lsw), litter weight at birt...

This study was conducted to investigate the effect of different estrus synchronization protocols followed by artificial insemination on response and conception rate Abergelle goats. Three protocols: (i) standard protocol associating progestogens, gonadotropins prostaglandins (P4 + eCG PGF2?), (ii) single injection prostaglandin (PGFS), (iii) double (PGFD) were evaluated compared a control group...
