The effects of smoking processes on the sensory and proximate components of two species of shrimp were evaluated. Sixty specimens of each species were distributed in a completely randomized design, with two treatments (T1 = hot smoking and T2 = liquid smoking), and fresh shrimps samples were used as control (T3). The sensory characteristics were evaluated using the 9 point hedonic scale and the acceptance index. The centesimal composition was evaluated based on 100 g from each treatment and the fresh samples. The data were submitted to one-way ANOVA and Tukey's test. The results of sensory analysis showed significant variations (p <0.05) for the attributes analyzed among the species, whereas among the smoking processes there was no significance (p >0,05). The acceptance rate was above 70% for amazonian prawn and 80% for white shrimp, regardless of the smoking method. The proximate analysis showed significant differences between the two smoking processes, hot and liquid, with moderet values of lipids, between 0.27% and 1.51%, and high protein values, of 24.61% 24.13%, for white shrimp and amazonian prawn, respectively. The smoking processes altered the sensory and chemical profile of the prawns, causing good acceptance and adequate nutritional constitution for smoked fish.

Effect of processing methods on consumer’s acceptability and proximate composition of yellow croaker was investigated. The experiment was completely randomized design where the treatments were the various processing methods employed. 12kg frozen yellow croaker fish were purchased, cut into chunks, divided into 4 groups of 3kg each, each group was salted and then subjected to different processing methods including: sun drying, deep- frying, solar drying and smoking. After processing, the products were subjected to organoleptic assessment using hedonic scale while the proximate composition was determined using standard experimental procedures.  The result of this study indicates that the odour and flavour of smoked fish product were significantly (p < 0.01) preferred by consumers above other products. Solar dried fish product had highest percentage crude protein followed by smoked fish product while smoked fish product had the highest crude ash. This study suggests that it is better to process yellow croaker by solar drying and smoking so as to get good nutrients.

The present work aimed to evaluate the behavior of ten fertility attributes of soil organic matter physical fractions and total organic carbon upon addition of three EM Bokashis to a Rhodic Ferralsol (FRr) and a Dystric Cambisol (CMd). An experiment was carried out in greenhouse in which the soils were placed into plastic trays and cultivated with tomato. A completely randomized design was used with four repetitions and factorial scheme of 2 × 3 + 2, consisting of two soils (FRr and CMd), three EM Bokashis (Poultry Manure Bokashi (BPM); CNPH Bokashi (BC); and Cattle Manure Bokashi (BCM)), and two controls (both soils without addition of Bokashi). The following fertility attributes were evaluated: pH, Ca2+, Mg2+, K+, Na+, P, SB, H + Al, CEC, andV. Particulate organic carbon (POC) and mineral-associated organic carbon (MOC) and total organic carbon (TOC) were also investigated. Finally, the Principal Component Analysis was conducted in order to identify possible patterns related to soils when fertilized with EM Bokashi. The addition of EM Bokashi increased the soil fertility and contents of POC. Different EM Bokashi presents distinguished effects on each soil. The PCA suggests that BPM presents higher capacity to modify the analyzed chemical attributes.

A 16-week trial evaluated the effects of ethanolic extract of Aspiliaafricana leaf (EeAaL) on the growth performance, carcass and egg characteristics of growing and laying quails. One hundred and eighty (180), one-week old Japanese quail chicks were assigned to six experimental diets (0, 2.5, 5, 7.5, 10% EeAaL or 0.02% oxytetracycline). Each treatment had 30 birdswhich were further subdivided into three replicates of 10 birds. Each replicate was housed in a pen under the deep litter system; feed and water were provided ad libitum.Growth performance and egg characteristics(egg quantity and quality) indices were subjected to the one-way ANOVA in a completely randomized design (CRD). No significant (P>0.05) effect of EeAaL was observed between treatments on the final body weight and daily weight gains of quails. Feed conversion ratio (4.95 – 5.28) was significantly (P<0.05) improved in quails fed 2.5 – 7.5% EeAaL diets. Zero mortality was observed in quails fed 5 – 10% EeAaL diets compared to other treatments. EeAaL supplementation reduced (P<0.05) the amount of fat deposition in quail carcass, thus improving the carcass quality. The efficacy ofEeAaL was more pronounced in laying than growing quails where significant (P<0.05) differences were observed on some external and internal egg characteristics, whereas egg composition did not differ (P>0.05) between treatments. Egg number, hen day production, albumen weight,yolk weight, shell thickness and yolk colour were significantly improved following dietary EeAaL  upplementation, indicative of strong growth promoting and stimulatory effects.Therefore, for improved carcass and egg performances up to 7.5% EeAaL shoud be supplemented intoquail diets.Keywords: Leaf extract, growth rate, egg characteristics, bush marigold, quails
