Megjegyzések:	The potential of Annona muricata leaf meal (SLM) as a feed additive for African catfish (Clarias gariepinus) was investigated through a 56-day feeding trial. The study began with a quantitative phytochemical analysis of SLM, followed by Gas Chromatography-Mass Spectrometry (GC?MS) of methanolic leaf extracts. 180 juveniles, averaging 151.12 ? 8.54 g, were randomly assigned to four groups, each with 45 fish and three replicates in a Completely Randomized Design. The groups?Control, T1, T2, and T3 were fed diets containing 0 %, 2.5 %, 5 %, and 7.5 % SLM, respectively. Phytochemical analysis revealed substantial amounts of phenols, flavonoids, alkaloids, and saponins. GC?MS identified 13 distinct compounds, including fatty acids, fatty acid esters, ethers and aldehydes. Fish were weighed at the study's conclusion, and blood samples were collected for hematological and serum lipid profile analysis. Condition factors and survivability were similar across all groups (p ? 0.05). However, final body weight (FW), weight gain, specific growth rate, total feed intake (TFI), and feed conversion ratio varied significantly (p < 0.05). The control group exhibited the highest FW (339.20 ? 3.16 g) and TFI (597.05 ? 6.65 g), with results comparable to T1. Conversely, TFI and growth progressively declined with increasing SLM levels, with T3 showing the lowest FW (299.62 ? 7.83 g) and TFI (541.06 ? 20.39 g). Hematological and serum profile indices were similar across groups (p ? 0.05). These findings highlight the nutritional and ethnopharmacological relevance of A. muricata leaves. It was, therefore, concluded that SLM can be included in catfish diets at 2.5 % without negatively affecting growth or health.

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.
