This study examined the effect of Parkia biglobosa (Locust bean) husk extract and honey blend on the chemical, sensory and bacterial qualities of traditional West African soft cheese. In this study, soft cheese was treated with blends of honey and ethanol extract of P. biglobosa husk at varied levels of 0, 1, 2, 3 or 4% (being percentages of the milk used) for both of the components immediately after coagulation. Seven (7) treatments were studied in a completely randomized design and assessment of the proximate composition and sensory attributes of the cheese was done. The Total Bacterial Count (TBC) was also monitored throughout a five days period. The result revealed that the control cheese was highest in moisture, and ash, but lower in cheese fat content. General acceptability was highest for the cheese curds fortified at 1:3, 2:2 and 3:1 % Honey/P. biglobosa. The 3/1: Honey/P. biglobosa treated cheese showed the highest inhibition rate against bacterial growth. The treatments fortified with 1:3, 2:2 and 3:1 % Honey/P. biglobosa also had the lowest TBC for the days of microbial assay. Seratia odonrifera and Seratia liqueficiens were prominently identified at days 2 and 4 of storage. The study recommend the use of 1:3 , 2:2 and 3/1 % Honey/ P. biglobosa cheese curd fortification as an improvement of the nutritional, sensory and bacterial attributes of West African soft cheese.

The high nutrient value and the high demand for cheese worldwide has necessitated the adoption of cheese alternatives including Soybean cheese, and different methods of processing it. This study was designed to determine the replacement value of these cheese types by comparing the nutritional, sensory, economic and bacterial attributes of differently processed cheese from cow milk and soybean (cow cheese and soya cheese respectively). Thirty samples each of cow cheese (boiled and fried) and soya cheese (boiled, fried, pepper-coated and egg-coated) constituted six treatments (T1 to T6). The cheese values and bacterial attribute of these six treatments were compared using a Completely Randomized Design. Results revealed that protein was highest in fried soya cheese, then the egg coated soya cheese, but lowest in the pepper coated soya cheese. The sensory values of egg coated soya cheese sample was highest. The pepper coated soya cheese had the highest content of tannins, isoflavones, steroids and phenols, while the fried cow milk cheese had the highest content of alkaloids and terpenoids. The pepper coated soyabean cheese (T5) had lowest bacterial count for the first two days of storage on the shelf. The fried cow cheese (T2) was also low in bacterial count, but highest in cost. The widely prevalent bacteria species in the cheese samples studied include Enterobacter aerogenes, Staphylococcus aureus and Lactobacillus plantarum. It was concluded that the freshly prepared cow cheese supplies calcium and sodium abundantly and is low in anti-nutritive factors, but the nutrients contained depreciates fast with storage while the highly nutritious and acceptable egg coated soya cheese and the phytochemicals-rich pepper coated soyabean cheese are highly recommended as lower cost cheese substitutes to enhance protein supply and bioavailability.

This studywas carried out to determine the utilization and the optimumlevel of offer of bitter leaf (Vernonia amygdalina) meal (BLM) by West African Dwarf (WAD) goats. In a 20-week trial, twenty four WAD goats of both sexes, 5-7 months old, were randomly allotted to four treatments of graded levels of BLM(0% BLM(Control diet), 15% BLM, 30% BLMand 45% BLMdiets) in a completely randomized design to determine the utilization of bitter leafmeal as feed for goats. The dietswere used as supplements to a basal ration of Panicummaximum. Two digestibility trials were carried out. The digestible ether extract intake and digestible organic matter of goats on 0% BLM were significantly (P<0.05) higher than the values obtained for goats on bitter leaf meal diets. The average daily weight gain (g/day) for goats on 0% BML was significantly (P<0.05) higher than that of others. There were significant (P<0.05) differences in the percentage mortality of the goats fed experimental diets. The percentagemortality of goats on 30% and 45%BLMwere significantly (p<0.05) higher than that of others. It is concluded that bitter leafmeal can be included in the diets of (WAD) goats up to15%without any deleterious effect.

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.

Abstract. The study of carcass and meat quality of four male genotypes namely: Thai native (TH), crossbred (Thai native x Barred Plymouth Rock; THB), Barred Plymouth Rock (BPR) and Shanghai (SH) chickens was conducted. Three hundred and twenty birds receiving from four equal groups were allotted in Completely Randomized Design (CRD). They were fed from one day and slaughtered at 16 weeks of age. Breast (M. pectoralis major) and thigh (M. biceps femoris) muscles were investigated for meat quality. TH had lower slaughtered weight (P<0.001) but higher lean : bone as well as less bone percentage (P<0.05) than all groups. Thigh muscle fiber of TH had higher type I and lower type IIB whereas there were similar in breast muscle fiber. Meat quality in terms of IMF, cholesterol and triglyceride contents as well as n-3 fatty acid and the ratio of n-6/n-3 of Thai indigenous male strain was more favorable compared to those all genotypes. Breast and thigh muscle were higher in shear force value and collagen content but the sensory evaluation was not significantly different. Since they were similar in sensory evaluation, the male layer and the male crossbred chickens have the potential to substitute TH in a market serving consumers who prefer chewy chicken meat.

Enzyme Complexes

Two experiments were carried out to investigate the effect of “on top” addition of different enzyme complexes, the enzyme α-galactosidase and three sources of the enzyme phytase available on the market, in broiler diets. In the first experiment, 1260 one-day-old Cobb 500® chicks were distributed into seven treatments in a completely randomized design (CRD) with six replicates and 30 birds/replicate. Treatments consisted of combinations of different enzyme complexes, namely, complex A (phytase, protease, xylanase, ß-glucanase, cellulase, amylase, pectinase), complex B (protease and cellulase) and complex C (xylanase, amylase and protease); isolated α-galactosidase (GAL); and three sources of phytase (P1, P2 and P3) in the diet. The treatments were formulated as follows: T1 - basal diet (BD); T2 - BD + enzyme complex A + enzyme complex B (BDAB); T3 - BDAB + GAL; T4 - BD + complex A + GAL; T5 - BD + complex C + P1 + GAL (BDCG); T6 - BDCG + P2; and T7 - BDCG + P3. The following variables were measured in the experimental period of 42 days: feed intake (FI), weight gain (WG), average final weight (AFW), feed conversion (FC), and carcass yield. Significant differences occurred for AFW, WG and FC in the pre-starter phase. In the second experiment, 112 Cobb 500® chicks aged 25 days were distributed into seven treatments in a CRD with four replicates and four birds/replicate. Treatments were the same as in the first experiment. Nutrient digestibility was evaluated in an experimental period of seven days. Differences were found in the metabolism coefficient of ether extract (MCEE). Dietary inclusion of enzyme complexes improves the AFW and WG of chickens from 1 to 7 days of age and MCEE in the grower phase.

The present research was conducted to discover antimicrobial compounds in methanolic leaf extracts ofJatropha curcasandAndrographis paniculataand ethanolic leaf extract ofPsidium guajavaand the effectiveness against microbes on flower preservative solution of cut Mokara Red orchid flowers was evaluated. The leaves were analyzed using gas chromatography-mass spectrometry. A total of nine, 66, and 29 compounds were identified inJ. curcas,P. guajava, andA. paniculataleaf extracts, with five (88.18%), four (34.66%), and three (50.47%) having unique antimicrobial compounds, respectively. The experimental design on vase life was conducted using a completely randomized design with 10 replications. The flower vase life was about 6 days in the solution containing theP. guajavaandA. paniculataleaf extracts at 15mg/L. Moreover, solution with leaf extracts ofA. paniculatahad the lowest bacterial count compared toP. guajavaandJ. curcas. Thus, these leaf extracts revealed the presence of relevant antimicrobial compounds. The leaf extracts have the potential as a cut flower solution to minimize microbial populations and extend flower vase life. However, the activities of specific antimicrobial compounds and double or triple combination leaf extracts to enhance the effectiveness to extend the vase life need to be tested.
