A total number of 50 meat retailers (beef, chevon, broiler, mutton and chicken) were surveyed through a structured questionnaire for collecting necessary data and latent variables. Collected data were analyzed through descriptive statistics and regression model. Awareness were created by displaying a poster in front of meat retailer’s shop and distribution of Covid-19 kit which contains soap, sanitizer, face mask, hair net and hand gloves. Practical demonstration was given how to wear the kit materials. Meat retailers were very happy to wear from hypothetical observations. Results showed that average age, education and family size of meat retailers were 41.86 years, 5.96, and 6.16, respectively. The price of beef before, during and after lockdown was BDT 523.52, 477.64 and 542.00, respectively. Simarlry, the price of broiler meat and sonali chicken meat before, during and after lockdown was BDT 129.68, 95.59, 137.65; 182.50, 167.50, and 217.50, respectively. During Covid-19 situation the income of meat retailers became much lower as compared to any other critical conditions. About 100% meat retailers faced various problems towards buying and selling of animals, lack of consumers, and lack of demand for meat. The prices of all kinds of meat namely beef, chevon, and chicken meat became drastically lower during pandemic. About 84% meat retailers used face mask, 60% maintained physical distance and 2% people tested for corona virus. During lockdown 98% meat retailers did not get any financial support from government, NGOs or any other private organizations. They did not get any kind of help to create awareness from the government or local authority. Despite facing all these problems, 98% meat retailers would like to continue their meat business. Meat retailers demanded subsidy to maintain their livelihood during lockdown. In conclusion, awareness was created through poster and supplied Covid-19 kit among meat retailers and they need government incentive during lockdown to maintain their livelihood since income of meat retailers was negatively and significantly decreased.","PeriodicalId":18312,"journal":{"name":"Meat Research","volume":"113 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80741438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, raw beef liver sample was divided into five treatments groups as T1 (day 1or control), T2 (day 2), T3 (day 3), T4 (day 4) and T5 (day 5). Sensory attributes, proximate composition, pH value, cooking loss, free fatty acids (FFA), peroxide value (POV) and microbial load such as total viable count (TVC), total coliform count (TCC) and total yeast mould count (TYMC) analysis were carried out for each treatment. The results show that color, odor, juiciness, and tenderness were significantly (P<0.05) decreased with increase the storage periods. Dry matter and ash contents were significantly (P<0.05) increased, whereas, crude protein and either extract were decreased with increase storage periods. Consequently, the cooking loss (%), FFA and POV values were significantly (P<0.05) increased, while pH value was significantly (P<0.05) decreased with the increase of storage periods. Moreover, TVC (log CFU/g), TCC (log CFU/g), and TYMC (log CFU/g) were also showed significantly (P<0.05) higher value for T3 and T5 compared to T1 . These findings suggest that shelf life of raw beef liver at refrigeration temperature (4°C) may be maximum three days with minor changes of quality.","PeriodicalId":18312,"journal":{"name":"Meat Research","volume":"os-27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87038802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, sausages were prepared into four different groups. They were as follows: broiler breast meat sausage without bee honey, spent hen breast meat sausage without bee honey, spent hen breast meat sausage with 2% bee honey and spent hen breast meat sausage with 4% bee honey. All parameters were analyzed at 0, 15th and 30th days of storage time. Significant differences were found in pH, the percentages of dry matter (DM), crude protein (CP) and ether extract (EE), while no significant differences were found in the percentage of cooking loss and ash of sausage batter. While analyzing the different types of sausages, CP, ash and EE content of all treatments differ significantly (p<0.05). In contrast, CP and EE content increased significantly (p<0.01), while ash content decreased significantly (p<0.01) with the advancement of different days of intervals. The FFA, POV and TBARS values were increased significantly (p<0.01) with prolonging the storage time. Lightness (L*) and yellowness (b*) did not differ among different sausages and time of intervals. Redness (a*) was significantly higher in broiler breast meat sausages without bee honey. Redness increased significantly with the advancement of different days of intervals. Flavor and overall acceptability were found significantly lower in spent hen breast meat sausage without bee honey. Bee honey increased the flavor, juiciness, tenderness and overall acceptability of spent hen breast meat sausages similar to broiler breast meat sausage.

In experiment 1, 312 one-day-old Ross×Ross broiler chicks with similar body weight were randomly assigned to 4 dietary treatments (C, control having no amino acids; Arg, a diet with 0.5% L-Arg; Gln, a diet with 0.5% L-Gln and Trp, a diet with 0.5% L-Trp), each containing 6 replicate cages with 13 birds per cage. For further confirmation, experiment 2 considered similar treatments as of experiment 1. Body weight and feed intake were measured weekly. At 2nd and 6th weeks of age, 12 birds per treatment were killed in both experiments to measure gut morphology, serum IgG and IgA and meat quality of broilers. In Expt 1, results showed that dietary Arg, Gln and Trpsupplementation significantly increased (P< 0.05) weight gain and feed intake of broilers than those of control group. In experiment 2, a similar performance trend was obtained compared to Experiment 1. Circulating levels of IgG and IgA were increased with supplementation of AAs in the diet. In both experiments, the breast and drumstick muscles of the group of birds feed amino acids had a higher pH and redness (a*) values, but lower lightness (L*) and yellowness (b*) values of meat. Chicks fed diet with Arg, Gln and Trp had longer villi height and villi to crypt depth ratio, and shorter crypt depth as compared with the control (P<0.05). Thus the addition of Arg, Trp and Gln each at 0.5% in the diet of broiler chicken enhanced growth performance, immunity, gut morphology and meat quality characteristics of broiler.","PeriodicalId":18312,"journal":{"name":"Meat Research","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86850097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ninety six male lambs were reared by 16 farmers at two upazila namely Paba and Godagari in Rajshahi district. Lambs were slaughtered at 6 (T1 ), 9 (T2 ) and 12 (T3 ) month‘s age. Each farmer kept 6 lambs (Two lambs for each 3 age category). Four types dressing percentages were measured; DRSWIEO (on the basis of slaughter weight and hot carcass weight including edible offal), DRSWEXEO (on the basis of slaughter weight and hot carcass weight excluding edible offal), DREMIEO (On the basis of empty body weight and hot carcass weight including edible offal) and DREMIEO (On the basis of empty body weight and hot carcass weight excluding edible offal). All lambs received maternal milk and a supplementation of commercial concentrate @ of 1.5% of live weight up to slaughter and allowed to graze for 8 hours a day on natural grassland. The Redness (a) was more (18.80±0.06) in 12 month‘s lamb and Yellowness (b) was higher (10.17±0.06) in 6 month‘s lamb. Ultimate pH (pHu ) varied significantly among age groups and it was lowest (5.62±0.01) at 6 month and highest at 9 month. Drip loss (DL) was highest on young and lowest in aged lambs.
