The feed rate of substrate during fed-batch fermentation affects many physiological variables such as specific growth rate, cell mass accumulation, substrate feed per cell, substrate feed to maintenance, carbon starvation stress, by-product formation and population segregation. These variables are known, or can be theoretically assumed, to influence protein production. Feeding strategies such a...

BACKGROUND The rate of breast-feeding in Israel has increased over the last two decades but is still lower than rates in other developed countries that have taken an active role in promoting breast-feeding. OBJECTIVE To determine breast-feeding patterns and the association between sociodemographic characteristics and breast-feeding in the Tel Aviv district. METHODS The mothers of infants ag...

in order to study the effect of garlic crude extract on growth rate and histopathology of liver, kidney and intestinal bulb, 120 fishes with initial mean weight of 95±22 g were divided to four groups. they were fed with 0, 10, 20 and 40 g/kg garlic crud extract in food for 1 month. at the end of experimental period, the growth rate was estimated and samples from liver, kidney and intestinal bul...

the aim of this study was to show the effect of four feeding regimes on thyroid hormones concentrations, growth performance and food coefficient in rainbow trout applied through 4 treatments and 3 replications in winter 2006. in this research, samples of rainbow trout with an initial mean weight (so) 47.19±0.42 used in each rearing unite. fish were fed twice a day ad libitum as follows: treatme...

Measurements of ventilation and respiratory mechanics were made before and after tube feeding in 24 infants. In 12 infants with the respiratory distresssyndrome tidal volume tended to fall after feeding; as the respiratory rate increased after feeding; as the respiratory rate increased after feeding, minute ventilation remained unchanged. Hypoventilation is therefore unlikely to be the cause o...

This study was aimed to observe the correlations among egg, larvae and maternal characteristics of Persian sturgeon. A total of 41 females were used and the variables including fertilization rate, incubation survival rate, larvae survival rate during yolk sac absorption (before feeding), and larvae survival rate after first feeding were determined. As a result, fertilization rate was positively...

INTRODUCTION Selection of the artificial membrane feeding technique and blood meal source has been recognized as key considerations in mass rearing of vectors. METHODOLOGY Artificial membrane feeding techniques, namely, glass plate, metal plate, and Hemotek membrane feeding method, and three blood sources (human, cattle, and chicken) were evaluated based on feeding rates, fecundity, and hatch...

Breast feeding has a great impact on the infant morbidity and mortality. According to Pakistan Demographic and Health survey (PDHS) infant mortality rate is 78 deaths per 1,000 live births. World Health Organization recommends that exclusive breast feeding for six months can decrease infant mortality rate by one-third. The objective of the study was to find out how the mode of delivery had impa...
