Studied was the effect of biomass of freshwater microalgae on the dynamics of the weight gain in calves. A total of ten test calves aged 10 days were treated three time subcutaneously at 15-day intervals with 5 cm3 each of a 10 per cent suspension of biomass of such algae. Higher gain was established on the 10th, 25th, 40th, 60th, and 90th day after birth as compared to the 5 control calves. It was also found that the daily growth rate with the test animals was higher than the that of the control -- 112, 84, 87, and 62 g,-respectively, however, the difference proved statistically insignificant. Significant in this sense was the rise of the gain in the twice treated hypotrophic calves at 15-day interval as compared with the untreated animals. The total gain with the calves treated for 30 days was 3.9 g higher than that with the control calves. The daily gain was 837 +/- 23 g for the test animals and 707 +/- 13 g for the control animals.
研究了淡水微藻生物量对犊牛体重增加动态的影响。总共10头10日龄的试验犊牛，每隔15天皮下注射3次，每次注射5立方厘米10%的此类藻类生物量悬浮液。与5头对照犊牛相比，试验犊牛在出生后的第10天、25天、40天、60天和90天体重增加更多。还发现试验动物的日生长率高于对照动物，分别为112克、84克、87克和62克，然而，差异在统计学上不显著。从这个意义上说，每隔15天接受两次治疗的营养不良犊牛与未治疗的犊牛相比，体重增加显著。接受30天治疗的犊牛总增重比对照犊牛高3.9克。试验动物的日增重为837±23克，对照动物为707±13克。
