摘要

本文研究了不同代谢能水平的混合饲料在虹鳟鱼仔苗和鱼苗养殖中的有效性。本试验旨在探讨不同能量供给水平对鳟鱼生产性能的影响。为此,采用类似物法组成5个实验组。均衡期,实验鱼食用对照组饲料。在主要时期,鳟鱼饲料代谢能水平在14 ~ 18 MJ之间。的结果进行研究是建立在配合饲料能量的增加鳟鱼幼虫和弗莱从16到18 MJ导致体重的增加11.1% (p < 0.05)和强度增长- 5.6 -14.2%,而能量的减少到14 MJ /公斤可能有助于减少(p < 0.05)质量的11.9%,增长强度下降6.0 - -14.7%。结果表明,与能量含量为16 MJ / kg的饲料相比,饲料中能量含量为18 MJ / kg的鳟鱼幼苗和鱼苗每增重1 kg的饲料消耗量降低了5.1%,饲料中能量含量为14 MJ - 4.8%。实验鱼在整个实验过程中的安全性很接近,在83.1% ~ 84.9%之间。然而,与消耗代谢能营养价值为16 MJ的饲料相比,将该指标分别降低或增加到14或18 MJ,在经济上是最可行的。

EFFICIENCY OF USING MIXED FEEDS WITH DIFFERENT ENERGY LEVELS IN FEEDING LARVAE AND FRY RAINBOW TROUT
The article considers the effectiveness of the use of mixed feeds with different levels of metabolic energy for the cultivation of larvae and fry of rainbow trout. The aim of the experiment was to establish the influence of different levels of energy supply of trout on its performance. For this purpose, five experimental groups were formed by the method of analogues. During the equalization period, the experimental fish consumed feed of the control group. In the main period, the level of metabolic energy in trout feed ranged from 14 to 18 MJ. As a result of the conducted researches it is established that the increase of energy content in compound feed for trout larvae and fry from 16 to 18 MJ contributes to the increase of their weight by 11.1 % (p < 0.05) and growth intensity - by 5.6-14.2 %, while the reduction of energy content to 14 MJ / kg contributes to a probable decrease (p < 0.05) in mass by 11.9%, and a decrease in growth intensity by 6.0-14.7 %. It is proved that the feed consumption per 1 kg of weight gain in trout larvae and fry, which received feed with an energy content of 18 MJ was lower by 5.1 %, and with its content of 14 MJ - 4.8 % higher compared to fish consuming feed with an energy content of 16 MJ / kg. The safety of the experimental fish throughout the experiment was close and ranged from 83.1 to 84.9 %. However, it is most economically feasible to grow trout that consume feed with a nutritional value of 16 MJ of metabolic energy, compared with a decrease or increase of this indicator to 14 or 18 MJ, respectively.
