  diet
Chinese Early Cretaceous birds had experienced a significant differentiation in morphology, flight, diet and habitat.
      
For each test group, 20 loaches with similar body size (5.17-7.99 g; 11.79-13.21 cm) were selected and kept in aquaria with dechlorinated water at (22±1)°C and fed a commercial diet every 48 h.
      
Diet composition of post-metamorphic bullfrogs (Rana catesbeiana) in the Zhoushan archipelago, Zhejiang Province, China
      
The analysis of the stomach contents shows that, for adult bullfrogs, the most important prey (by diet volume) overall were Decapoda, Coleoptera, Odonata, Mesogastropoda, Raniformes, and Cypriniformes.
      
Moreover, the prey size and diet volume increased with the body size of both adult and juvenile bullfrogs.

1.The nutrient content of yeast (Condida Y-17) grown on n-alkane studied in this experiment was comparable to that of the same type of yeast produced in other countries. Its content of lead, arsenic, mercury and benzo (a) pyrene were within the limit proposed by the Protein-Calorie Advisory Group of the United Nations System. The Content of its residual n-alkanes and total aromatic hydrocarbons were within or a little over that limit. It is a good supplementary protein feed.2.The corrected PER values were, yeast grown on n-alkane 1.18; deli pid and denucleic acid yeast grown on n-alkane 1.16; brewer's yeast 1.52; full fat soybean meal 1.81. The PER of yeast grown on n-alkane was significantly lower than those of other samples. When 0.3% DL-methionine was added to the diet, the corrected PER values increased: n-alkane grown yeast 2.32; delipid and denucleic acid n-alkane grown yeast 2.49; brewer's yeast 2.35; full fat soybean meal 2.28. The corrected PER value of casein used for correction was 2.43, it was standardized with ANRC reference protein (PER = 2.50).3.Yeast grown on n-alkane with and without removal of lipids and nucleic acid was fed to groups of rats at a dietary level of 25% and 35% respectively for 1 year. A stock diet group and a brewer's yeast diet group were used as control. In the first 3 months the weight gain and feed consumption of the rats fed n-alkanc grown yeast diet were lower than those of the two control groups. The male rats were more sensitive to the change of diet. In the later 9 months the difference of weight gain among different groups were not significant. The concentration of haemoglobin, red cell counts, white cell counts, GPTase activity, serum cholesterol levels and serum urea levels determined at the beginning and the end of the experiment were all in the normal ranges. The concentrations of n-alkanes and odd-chain fatty acids in the adipose tissue of the n-alkane grown yeast group were higher than those of the two control groups, and the difference was highly significant. The concentrations of total aromatic hydrocarbons and benzo(a) pyrene in the muscle of different groups of rats were 0.4-0.6 ppm and 0.4 ppb respectively. No detrimental effect was observed in pathological examination.4.When 5% fish meal or 3.5% casein was added to the 25% n-alkane grown yeast diet, the weight gain and feed consumption of weanling rats were improved significantly, though it was still inferior to those fed with stock diet.5.Strongly growth depressive effect was noted as the level of n-alkane grown yeast was increased to 20% in the diet. This depressive effect was neither due to the toxicity of the residual n-alkanes and aromatic hydrocarbons, nor due to the deficiencies of potassium and selenium in the diet. It might be the result of nutrient or nutrients imbalance of the diet. The appropriate amount of yeast grown on n-alkane used in mixed feed should not be more than 15%.

Weanlimg male rats fed on synthetic diet containing 1% succinylsulfa-thiazole and devoid of vitamin B12 and folic acid for 3-5 weeks, developed syndromes of the vitamins deficiency, i.e. poor food consumption, low growth rate, decrease in white cell count and marked increase in formimi-noglutamic acid excretion.Nevertheless, the others had an intake of vitamin B12 (0.02 μg/day/-rat) and folic acid (0.5μg/day/rat) for a 36-day period, also showed signs of vitamins deficiency. But when given a daily dose of 0.1 μg of vitamin B12 and 2.5 ug of folic acid, the rats had a good appetite and grew well, and excreted more formiminoglutamic acid than normal rats, when they were given a loading dose (0.05 g/rat) of histidine. Under the similar feed- ing condition, rat ingesting a daily dose of 0.3 ug of vitamin B12 and 7.5ug of folic acid, showed no obvious syndomes of the vitamins deficiency.After the rats were fed on the same diet and given with vitamin B12 (0.02 ug/day/rat) and folic acid (0.5ug/day/rat) for a 36-day period, the animals developed increased radiosensitivity. After total-body irradiation (700 rad), the food consumption, growth rate and survival rate in this group were lower than those in other groups ingesting individually 0.1 ug of vitamin B12 and 2.5 ug of folic acid or 0.3ug of vitamin B12 and 7.5 ug of folic acid daily.After irradiation, in the group of 0.02 ug of vitamin B12 and 0.5 ug of folic acid or 0.1 ug of vitamin B12 and 2.5 ug of folic acid in daily in-gestion there was a considerable increase in formiminoglutamic acid with a loading test of histidine(0.05 g/rat) than before. The results showed that the radiation intensified vitamins deficiency in rats.

Observations were conducted on 11 kinds of tissues and organs(brown adipose tissue, thymus gland, blood, heart, lungs, muscle, bone, kidneys, spleen, liver, and intestine) in experimental animals, which were fed on crops from endemic areas of Keshan disease and non-endemic areas for 8-13 weeks. The absorption and distribution of 75Se (Na2 SeO3) in above tissue and organs were studied. Results revealed that the absorption of Na2-SeO3 in experimental group fed on crops from endemic area was higher than control group fed on crops from non-endemic area. The gradient of distribution of 75Se in various organs was regular: The highest absorption was in kidneys, the lesser was in liver, spleen and thyrnus, the least was in muscle, heart and bones.In one week observation, the contents of 75Se changed as time passed, but the fluctuating changes of the two groups were different.The regular differences of 75Se absorption as above, revealed a distinction between endemic and non-endemic crops. Under the influences of the crops on experimental animals, there appeared more or less a condition of selenium deficiency, which proved that the soil-water-food chain had apparently influenced the selenium metabolism of the organisms.

以克山病病区和非病区粮饲养大鼠(饲料号为13和35)6—13周进行~(75)Se示踪代谢实验,观察11种组织脏器(褐脂、胸腺、血液、心脏、肺、肌肉、骨、肾、脾、肝、肠)~(75)Se(Na_2SeO_3)的吸收量和体内分布状况。结果表明,自由进食条件下,病区饲料组动物~(75)Se吸收量高于非病饲料组。其中以13号莜麦饲料组差异最为明显(A实验)。对饲条件下病区组动物~(75)Se的吸收量仍高于非病区组。但是差异程度较自由进食组为小(B实验)。各组动物体内不同组织脏器~(75)Se的分布梯度呈现一定规律性。皆以肾脏的吸收量为最高,其次是肝、脾脏及胸腺等,吸收量最低的是肌肉、心脏及骨骼。 在观察的一周之内,随时间的增加,~(75)Se于组织脏器中的含量,病区饲料组与非病区饲料组有不同的动态变化。 病区与非病区组间~(75)Se吸收量规律性差别,反映了病区组动物在病区出产的饲料影响下,体内硒不足或缺乏,表明病区与非病区出产的粮食存在着质的差异,证实了病区水土——食物链因素对动物机体硒代谢有明显影响。
