Feeding practices and nutritional status of infants in Morogoro Municipality, Tanzania.

Breast feeding practice especially exclusive breast feeding (EBF) is a major determinant of child growth and development. In Tanzania, most women breastfeed their infants for long periods, but many introduce alternative feeding too early in life. The objective of this study was to determine factors affecting EBF and the relationship between feeding practices and the nutritional status of infants.

Phenotypic and genetic parameters for body weights and antibody response against Newcastle disease virus (NDV) vaccine for Kuchi chicken ecotype of Tanzania under extensive management.

This study was carried out to estimate phenotypic and genetic parameters for body weights and primary antibody response (Ab) against Newcastle diseases virus (NDV) vaccine for Kuchi chicken ecotype of Tanzania managed extensively. Body weight was evaluated at 8 (Bwt8), 12 (Bwt12), 16 (Bwt16) and 20 (Bwt20) weeks of age, while Ab against NDV vaccine was evaluated at 6 weeks of age (2 weeks post-vaccination). Number of birds per trait varied from 373 to 430.
