This study compares the effects of different levels (0 to 50%) of Gliricidia sepiun leaves on the processing, proximate composition, and organoleptic characteristics of male and female rabbits using a 3 x 2 x2 factorial design. The effect of 8 weeks of cold storage at - 20+20 C on acceptability of the rabbit meat was also evaluated. The data obtained showed that the live-weight, dressing percentage, and fat content of the rabbits fed 25% Gliricidia sepium were higher than those from 0 % (control) or 50 % level at 10 weeks old. The total cooking losses were higher by 15 to 24% in the frozen roasts, due mainly to increased drip and evaporative losses which were also slightly higher in the female carcasses. The expressible moistrue index (EMI) increased in the frozen samples, and no significant difference (P>0.05) was found to be attributable to diet. The final moisture content and cook yield of the frozen samples decreased, whereas the ash content was not significantly affected by sex or diet. However, the protein and fat contents, and pH increased regardless of sex in all the cooked samples. The sensory evaluation results are suminarized as follows: (1) fresh roasts from rabbits fed 25% Gliricidia sepiun were preferred, possibly, influenced by tenderness scores and slightly higher fat content; and (2) meat roasts from the frozen samples did not differ on overall acceptability, although the palatability scores diminished at the end of 8 weeks of frozen storage, and panelists did not detect any significant differences (P>0.05) attributable to diet or sex.

The study evaluated the effects of level of feed offer on dry matter intake (DMI) , digestibility, the parts of plants selected and on the growth rate of West African dwarf (WAD) goats without resulting in toxicity. Seven different levels of feed offer ranging from 40g/kg0.75/day to 130Wkg0.75/day in increments of 15g/kg0.75) were fed to two groups of goats. The first group was fed 100% Gliricidia while the while the second was fed 50% Gliricidia and 50% Leucaena diet (50/50). The level of feed offer had significant effect on the DIM and digestible DMI (DDMI) of the goat (P < 0.01). The Leucaena intake in a 50/50 diet was always higher than the Gliricidia intake except at 55g1kg0.75 offer level. The level of feed offer had significant effects on the parts of plants selected (P < 0.01.) and on the growth rate. The leaf intake was statistically higher than the stem intake (P < 0.01). All the goats on 40g/kg0.75 and 55g/kg0.75 on a 100% Gliricidia diet lost weight while only those on 40g/kg0.75 lost weight on a 50/50 diet. There was no significant difference in the growth rate of goats on feed offer levels of 70g to 130g/kg0.75 (P > 0.05). The study indicate that goats performance was higher on a mixed browse diet than on Gliricidia alone. Goats performed best at 100g/kg0.75 offer level.

SUMMARYTwo experiments were conducted to compare the milk-producing value of dried forages in the form of cobs and pellets as replacements for a standard dairy concentrate. Four levels (0·33, 0·44, 0·55 and 0·66 kg/kg milk) of dried forage or standard dairy concentrate were offered in addition to a basal ration of 6 kg hay and 2 kg standard dairy concentrate. In both experiments the rate of eating by the cows of cobs was significantly slower (P<0·05) than that of pellets. No significant difference was found between the cobs and pellets in either experiment in their value for milk production. In Experiment 2 the standard dairy concentrate had a non-significantly higher (P>0·05) milk-producing value than the dried lucerne. Level of feeding had a significant positive effect on the milk yield (P< 0·001) of cows offered the dried grass and lucerne and on the milk solids- not-fat content (P<0·05) and live weight (P<0·01) of cows offered the dried grass, lucerne and standard dairy concentrate.

1. Nine groups of 4 litter-mate Wessex Saddleback gilts were divided on a within-litter basis between 4 treatments so that they were reared from 8 weeks of age to 200 1b. live-weight according to different levels of total feed intake; (a) a high level rising to 8·0 1b. meal per day at 200 1b. live-weight, (b) a medium level approximately 80% of the high, (c) a low level approximately 60% of the high and (d) changing from the low to the medium level between 14 and 16 weeks of age. From 200 1b. live-weight to mating at first heat after reaching 300 1b. all were fed to the medium scale (6·5 1b. meal per day), and all were treated alike during each of 3 pregnancies and lactations.2. Mean rate of growth from weaning to 100 1b. and from 100 to 200 1b. differed significantly between treatments (P<0·001), and mean efficiency of feed conversion of the low-plane group was significantly poorer than that of the high-plane group (P<0·05) from weaning to 100 1b. live-weight.3. All gilts, regardless of treatment, reached puberty at approximately the same age (25 weeks), with the result that mean weight at puberty differed markedly between treatments (P<0·001); 116, 154, 189 and 147 1b. for treatments (a) to (d) respectively.4. Gilts reared on medium and high planes of feeding exhibited oestrus less strongly than those reared on the low-plane, with the result that mean weight at successful mating was significantly greater in these two groups (P<0·05).5. Four gilts in the low-plane group and one in the high-plane group failed to conceive after repeated matings, but numbers were insufficient to indicate the significance of this.6. From the original 36 gilts, 27 first litters, 26 second litters and 25 third litters were produced and reared to 8 weeks of age. There was no significant difference between treatment groups in litter size at birth, mean weight of piglets at 3 or 8 weeks of age or total litter weight at weaning.7. Trouble from temporary collapse of the legs was experienced in all but one gilt of the high-plane group between 6½ and 7½ months of age.

The aim of the current study was to find out the effect of adding different levels of lemon extract to the chicken meatballs. Fresh lemon extract was incorporated into freshly prepared meatball and compared with 0.01 % beta hydroxyl toluene (BHT) and control (without antioxidant). For this purpose, chicken meatball samples were divided into four treatment groups; viz. T0 (Control), T1 (0.01% BHT), T2 (0.5 % lemon extract) and T3 (1 % lemon extract). The study was conducted in completely randomized factorial design. The samples were analyzed for determination of sensory, proximate components, physicochemical, biochemical and microbiological qualities at 0, 30th and 90th days of preservation. Color, flavor, Juiciness, tenderness and overall acceptability increased significantly (p<0.05) among different treatment groups than control and BHT group but decreased at different days of intervals. Dry matter (DM) content decreased significantly (p<0.05) with different treatment levels than control and BHT group and increased with days of intervals. Crude protein (CP), ether extract (EE) and Ash of all treatments were decreased significantly (p<0.05) among different treatment groups. Raw pH, cooked pH and cooking loss were decreased significantly (p<0.05) with different treatment levels than control and BHT group and decreased with days of intervals. Free fatty acid (FFA), peroxide value (POV) and thiobarbituric acid reactive substances (TBARS) value were decreased significantly (p<0.05) with different treatment levels than that of control and BHT group and increased with days of intervals. Total viable count (TVC), total coli form count (TCC) and total yeast mould count (TYMC) decreased significantly (p<0.05) at different treatment levels than that of control and BHT group. Therefore, it can be concluded that 1 % lemon extract for formulation of value-added chicken meatballs was enriched source as natural antioxidant. SAARC J. Agri., 18(2): 139-156 (2020)

The effects of soy cheese (tofu) and trisodium citrate concentration on the organoleptic characteristics of pizza cheese were studied. Flavor, texture, stretchability, appearance, and overall acceptability of pizza cheese samples decreased significantly with increased proportion of soy cheese. Statistically, the color of cheese samples made from different blends of tofu and trisodium citrate was similar to that in the control sample. Stretchability, appearance, and overall acceptability of pizza cheese samples increased but not significantly (p>0.05) as concentration of trisodium citrate increased. However, the scores of flavor did not show significant difference.

Purpose – This study aims to evaluate the effect of oat meal on the quality characteristics of restructured spent hen meat blocks. Spent hen meat is considered as poor because of comparatively higher toughness and less juiciness. Design/methodology/approach – Oat meal (1:1 hydration, w/w) was incorporated at the levels of 4, 6 and 8 per cent by replacing the lean meat in prestandardized restructured spent hen meat blocks formulation and assessed for physico-chemical and sensory quality. Findings – The product yield and pH of restructured spent hen meat blocks (RSHMB) were significantly higher at 8 per cent oat meal as compared to control. Shear force values of RSHMB with various levels of oat meal incorporation were significantly lower than control. There were no significant differences in the general appearance, texture, binding, juiciness and overall acceptability scores of RSHMB with different levels of oat meal and control. However, there was a marginal increase in binding and juiciness of RSHMB with increase in the level of oat meal. The optimum incorporation level of oat meal in RSHMB was adjudged as 8 per cent, which also resulted in reduction of production cost by Rs. 14.4/kg as compared to control. Research limitations/implications – The trials can be further carried to evaluate the storage stability of developed RSHMB. Originality/value – The paper has demonstrated potential of oat meal as an extender in the development of RSHMB, which also reduced the cost of production.

Oat (Avena sativa L.) is an underutilized cereal and is considered as a rich source of protein, minerals, lipids, β-glucan and other phytochemicals. It has an immense scope for its application in preparation of various nutraceutical and functional foods. Oat flour was incorporated with wheat flour at different concentrations for preparation of breads and noodles. Breads were prepared by incorporation of oat flour (OF) in wheat flour (WF) at different levels (0, 10, 15, 20 and 25%). Overall acceptability of breads decreased with increase in level of oat flour. However, breads were moderately desirable up to 20% replacement of WF with OF and slightly desirable at 25% level of replacement. Significant decrease in loaf volume of oat incorporated bread (OIB) was observed with increase in level of incorporation of OF in WF. Oat incorporated noodles (OIN) were prepared by substitution of OF in WF at proportion of 0, 10, 20, 30 and 40%. These were moderately desirable only up to 30% replacement of wheat flour with oat flour and slightly desirable thereafter. There was significant (P≤0.05) increase in proteins, crude fibres, ash and fat content but significant decrease in carbohydrate content and calorific value of processed products was recorded with increased incorporation of OF in WF. Results of organoleptic evaluation concluded that bread and noodles were moderately desirable up to 20 and 30% replacement of wheat flour with oat flour, respectively. Therefore, oat can be successfully substituted with wheat flour upto a level of 20% for bread and 30% for noodle preparation thereby, enhancing the nutritional components such as crude protein, fibre, fat and ash content in prepared products.

Background: The commercial rearing of native chicken has been gaining importance due to higher demand for natural and organic meat. In this context the present study was designed to compare the carcass and meat quality characteristics of native chicken reared under backyard system as compared to native chicken reared under farm setting in Karnataka.Methods: Sixty (30 backyard and 30 farm reared) native birds were used to evaluate the carcass characteristics viz., dressing per cent, yield of cut up parts and meat bone ratio. Breast muscle was used to evaluate physico-chemical (pH, WHC, colour, drip loss and cooking loss), compositional (proximate composition, cholesterol content and collagen content), structural characteristics (muscle fibre diameter, sarcomere length, shear force) and sensory characteristics.Result: A significant difference (P less than 0.05) in live weight, carcass weight and dressing per centage was evident in backyard native chicken (BNC) and farm reared native chicken with higher weight being recorded in FNC, whereas no significance could be observed in yield of various primal cuts between them. Physico-chemical and compositional characteristics revealed no significant difference, whereas farm reared birds had lower shear force and collagen compared to backyard birds. Sensory evaluation revealed no negative influence on any of the eating quality indicating that commercial rearing of native chicken could be advocated for faster growth of native birds without compromising on the quality of meat.

<p>The authors investigated the effect of different levels of calcium and phosphorus in the mixed fodder on mineral composition of Japanese quail skeleton. Experimental studies were carried out in the conditions of the Problematic Research Laboratory of Mixed Fodder Additives, National University of Life and Environmental Sciences of Ukraine (Kiev, Ukraine). We selected Japanese quail as the material for scientific and economic experience.</p><p>The experiment was conducted by groups-analogues method. Fodder was in the dry loose form. The difference in feeding was due to different levels of calcium and phosphorus in the feed for experimental groups. In the beginning of the experiment the experimental quail were similar regards live weight while in the end we did not detect significant difference in their mass. Nevertheless, we observed little decrease in live weight with increasing of phosphorus up to 1.4 % and calcium up to 3.5 %. We fixed that water content in the quail skeletons from Group 4, 5 and 6th study groups (calcium 4.0 %, phosphorus 0.8, 1,1 and 1,4 % respectively) were smaller in comparison with quails from Control, Group 2 and 3 (calcium content 3.5 % with the same level of phosphorus). We also determined increasing of dry matter content in the skeleton by 2.5 – 2.8 % while increasing the content of calcium and phosphorus in mixed fodder of quails-hens (Group 4, 5 and 6). The phosphorus content in quail skeleton depended on the level of phosphorus in the mixed fodder and can be up to 0.39-0.66 % in the bones. The simultaneous increase in the level of phosphorus and calcium in mixed fodder of experimental groups was accompanied by increase in the concentration of calcium and magnesium in the quail skeleton by 0.85–0.87 and 0.01–0.07 per cent respectively.</p>

This research was undertaken to evaluate the potential of different meat sources in producing acceptable suya when compared with the traditional beef suya in Nigeria. Five meat types viz: pork, beef, chicken, rabbit and chevon were used for this experiment. The sensory evaluation was conducted on the suya samples by a 20-man panel of judges using a 9-point hedonic scale to assess the colour, flavour, texture and overall acceptability of the samples. The results showed that beef, goat and chicken suya significantly maintained a better acceptance (P<0.01) than the pork suya. There was a significantly (P<0.01) positive response to the flavour of chicken and beef suya than the rest of the other samples. Texture wise, beef and goat suya were significantly (P<0.01) more acceptable than the rest. In overall acceptability, the beef and chicken suya showed no significant difference (P<0.01) from each other and were both rated the best among the samples. It is apparent from the overall results that both goat and chicken could successfully substitute for beef in the production of acceptable suya. The quality characteristics generally showed that both meat samples were comparable to the beef sample.
