Cím:	Optimizing feed utilization and reducing deterioration of African catfish feed with sodium propionate supplementation / Ifeanyi Emmanuel Uzochukwu, Patrick Emeka Aba, Nelson Ike Ossai, Hillary Chukwuemeka Ugwuoke, Krisztián Nyeste, Ndubuisi Samuel Machebe

Megjegyzések:	A 56-day, two-phased experiment was conducted to investigate the effect of sodium propionate (NaP) on the growth performance of African catfish and the feed quality. One hundred juveniles with an average body weight of 50.47 g ( ? 4.60) were procured and used for the study's first phase. Fish were randomly assigned to five groups (A, control group), B, C, D, and E) and replicated four times with five fish each. Respective groups were fed diets containing NaP at 0, 1.67, 3.33, 5.00, and 6.67 g kg 1 feed, respectively. For the second trial, the individual diets were analyzed for quality characteristics on 0-, 28- and 56-days of storage, using a mixed-model analysis of variance. Results showed significant differences in most growth performance parameters among groups except for the final body length and condition factor. Group C had lower final body weight (FW), weight gain (WG), average feed intake (AFI), specific growth rate (SGR), and higher feed conversion ratio (FCR) than the control. However, these parameters did not differ in Group D, which also showed lower AFI compared to the control. Increasing NaP decreased the sensory attribute scores of the feed and its crude protein (CP), ether, and ash levels while increasing moldiness, crude fiber, nitrogen-free extract, and thiobarbituric acid reactive substances (TBARs). NaP inclusion in feed resulted in a dose-dependent reduction in the feed deterioration, as seen in the lowered aggregate changes in sensory attributes, CP, moisture, and ash levels, with Group D having an optimal effect. The TBARs level (rancidity) decreased in Group B but increased in Group E during the study. The study concludes that there was a loss of fish feed quality with increasing storage time and that NaP particularly at 5.0 g kg 1 feed optimally improves feed utilization and effectively lowers feed deterioration for 56 days. Therefore, the use of NaP is recommended for improved aquaculture production.
