the effect of dietary sucrose on dna formation in rat liver and kidney compared with that of starch was studied. male, weanling rats were fed for 6 and 14 days on diets containing 68% 'sucrose or 68% starch, and liver and kidneys were examined for 1ilie amount and rate of formation of dna; and also for content of fat, protein, and moisture. food intake and weight gain were estimated. sucrose fe...

1. When resources are scarce, organisms are faced with critical challenges trying to optimize competing functions. Reproduction and immune function are both resource intensive and important to most species. Most studies have reported a down-regulation of immune function during reproduction. Conversely, it is unclear whether mounting an immune response can affect the reproductive process and few...

Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals p...

This study was conducted to evaluate foetal/pregnancy losses following slaughtering of food animals at Nsukka Municipal Abattoir Enugu State, Nigeria over a period three months (April June). The pregnancy status each animal determined tentatively by visual observation and palpation the exposed uterus after slaughtering. Attempts were made recover embryos from dams with structures suggestive flu...

Hormonally active substances (e.g. anabolic steroids) and residues of pharmaceutical drugs prohibited from use in food-producing animals (e.g. chloramphenicol or metronidazole) are monitored in biological matrices (tissues, urine, blood plasma) as part of regular official tests for the presence of banned substances in animals intended for food production. Any such residua found in farm animals ...
