摘要
泥鳅营养丰富,全球对泥鳅的需求很少,尤其是具有观赏价值的泥鳅。热鳞头鱼是泥鳅重要的食用品种,市场价格较高,但有关其营养需求和生殖生物学方面的资料有限。因此,本研究旨在详细分析维生素饲料对热乳杆菌圈养成熟和繁殖性能的影响。在含23% cp的基础饲料中添加3种不同剂量的维生素A、C和E,饲喂育仔鸡90 d。记录生殖力、GSI、性腺组织学、激素(皮质醇和孕酮)变化、育种性能和生长参数。不同处理对雌鲟的生长和繁殖性能有显著影响。在所选维生素中,维生素C添加量为150 mg /kg时,最大平均增重(2.51±0.043 g)、平均增重率(70.74±1.219)、平均DGR(0.16±0.003)和平均SGR(3.13±0.0037)。组织学观察表明,饲粮中添加200 mg/kg维生素e时,热乳杆菌的成熟度最高,各处理的平均估计生长和成熟参数均高于对照组(p<0.05)。所得结果采用SPSS- 22.0中Duncan多元极差检验的单因素方差分析(One way ANOVA)进行统计分析,比较各处理间生长参数的显著性差异,并结合现有文献进行讨论。
Effect of Vitamins A, C and E on the Bio-Growth Performance and Captive Maturation of Lepidocephalichthys thermalis
Loaches are highly nutritious and global demand has been recognized for only few species especially of ornamental importance. Lepidocephalichthys thermalis is an important food species of loach fetching high market price but there is limited data related to its nutritional requirements and reproductive biology. Therefore, a detailed study was carried out to analyze the effect of vitamin enriched diets on the captive maturation and breeding performance of L. thermalis . Vitamins A, C and E were incorporated at three different doses in basal feed containing 23% C.P and fed to brooders for a period of 90 days. Fecundity, GSI, gonad histology, hormone (cortisol and progesterone) variations, breeding performance and growth parameters were recorded. Significant differences in the growth and breeding performance of female brooder under different treatments were noted. Among the selected vitamins, incorporation of vitamin C at 150 mg /kg of diet resulted in maximum mean weight gain (2.51 ± 0.043 g), mean weight gain percentage (70.74 ± 1.219), mean DGR (0.16 ± 0.003) and mean SGR (3.13 ± 0.0037). Based on the histological observation, maximum maturity of L. thermalis was obtained when fed with diet incorporated with 200 mg/kg vitamin E. All the treatments recorded higher mean estimated growth and maturation parameters when compared to control and were significantly different (p<0.05). The results obtained were statistically analysed using One way ANOVA following Duncan multiple range test in SPSS- 22.0 to compare the significant differences in growth parameters among all treatments and discussion was made in the light of available literatures.
