The research purpose was to determine the utilization of bay meal (SyzygiumpolyanthumWalp) microflora, and carcass quality of broiler. The research method was used completely randomized design with 5 treatments and 4 replicates. The materials used for this research were 80 unsex 15 days old with average body weight 307.725±22.17 g/head. The treatments used for research were dietary with T0 (basal feed), T1 (basal feed + 1% bay leaf meal), T2 (basal feed + 2% bay leaf meal), T3 (basal feed + 3% bay leaf meal), T4 (basal feed + 4% bay leaf meal). The parameters observed were intestinal characteristic bacteria (lactic acid bacteria, Escherichia coli, and Salmonella sp.) and (carcass percentage, abdominal fat, organ visceral weight, breast meat cholesterol). The data analysis was the analysis of variance (anova) and continued by Duncan Multiple Range Test. The results showed that using bay leaf effect as in feed has significant difference (P<0.05) on lactic acid bacteria and Escherichia coli and significantly different (P<0.01) (breast meat cholesterol) but didn’t significant difference (P>0.05) on carcass percentage, abdominal fat and organ visceral weight. The addition of 4% bay leaf gave the best effect on microflora, and breast cholesterol quality of broiler.

The present study aimed to investigate the effect of feeding fermented mixture of cassava pulp and M. oleifera leaf meal (FCPMO) on the breast meat characteristics of broiler chickens. From day 8 onward, 400 Lohmann broiler chicks were allotted to four dietary groups included CONT (maize-soybean-based feed with no additive), BACI (maize-soybean-based feed supplemented with 0.1% zinc bacitracin), FERM (feed containing 20% of FCPMO) and FERB (feed containing 20% of FCPMO and 0.1% probiotic Bacillus subtilis). At day 35, one male chick from each replicate (10 chicks per treatment group) was taken and slaughtered. After being eviscerated and de-feathered, sample of breast meat was obtained for the assessment of meat characteristics. Results showed that feeding FCPMO had no effect (P>0.05) on pH and water holding capacity (WHC) of breast meats. Compared to other groups, FERB meat had higher (P<0.05) cooking loss. FERM and FERB meats had lower (P<0.05) moisture content than that of CONT and BACI meats. Feeding FCPMO with or without B. subtilis increased (P<0.05) crude protein content of breast meats. Feeding FCPMO resulted in lower (P<0.05) fat content in the breast meat. Compared to other meats, breast meats from BACI had higher (P<0.05) ash content. Cholesterol was lower (P=0.08) in FERB than in BACI and FERM meats. The 2,2-diphenylpicrylhydrazyl (DPPH) IC50 values were higher (P<0.05) in meat of CONT than that in other groups. Feeding FCPMO resulted in higher (P<0.05) polyunsaturated fatty acids (PUFA), lower (P<0.05) monounsaturated fatty acids (MUFA) and had no effect on saturated fatty acids (SFA) contents of broiler breast meats. In conclusion, feeding FCPMO produced healthy broiler meat as reflected by the higher contents of protein, PUFA and antioxidants, and lower fat in meats.

This study investigated the breast meat proximate composition and quality indicators in relation to response of broilers to the following dietary treatments (T): positive control (+C; with 668 mg salinomycin and 500 mg zinc bacitracin per kg of feed); Moringa oleifera leaf meal (MOLM) was fed at a low level (ML; 1–5 g/kg feed, depending on growth stage), a medium level (MM, 3 times the low level) or a high level (MH, 5 times the low level); and a negative control (–C; without supplementation) for 35 days. At postmortem, the carcass weight, and breast muscle pH at 45 min (pH45) and 24 h (pH24) were recorded. At 36 h postmortem, breast muscles were excised, weighed and stored in a refrigerator at 4°C to measure pH, colour (CIE-L*, lightness; a*, redness; and b*, yellowness) and cumulative drip loss over eight consecutive days. Chroma (C*) and hue angle (h) were calculated. The –C had the highest (P > 0.05) dressing percentage and chilled carcass weight, and ML had the lowest. Breast meat fat and energy contents were highest (P < 0.05) in +C and MOLM supplemented diets, and lowest in -C. Dietary treatments had no effect on pH at postmortem and during storage over time. Cumulative drip loss increased with each day of storage, and it was highest (P < 0.05) in +C and lowest in MH. Dietary supplementation of MOLM significantly (P < 0.05) reduced lightness, but increased redness, yellowness, chroma and the hue angle during storage over time. In conclusion, dietary supplementation of M. oleifera leaf meal had positive effects on proximate composition and shelf-life quality indicators of broiler breast meat.

ntroduction: Detection and examination of proper number of lymph nodes in patients after rectal resection is important for next treatment and management of patients with rectal carcinoma. There are no clear guideliness for minimal count of lymph nodes, variant recommendations agree on the number of 12 (10−14) nodes. There are situations, when is not easy to reach this count, mainly in older age groups and in patients after neoadjuvant, especially radiation therapy. As a modality for improvement of lymph nodes harvesting seems to be establishing of defined protocols originally designed for mesorectal excision quality evaluation. Methods: The investigation group was formed by patients examined in 2 three-years intervals before and after implementation of the protocol. Elevation in count of harvested lymph nodes was rated generaly and in relation to age groups and gender. Results: The average count of lymph nodes increased from 10 to 15 nodes, in subset of patients whose received neoadjuvant therapy from 7 to al- most 14 nodes. The recommended number of lymph nodes was obtained in all investigated age groups. By the increased number of lymph nodes, rises also possibility of positive nodes found, that can lead to upstaging of the disease, in subset of patients whose received neoadjuvant therapy it is more than 4%. Conclusion: Our conclusions show, that forming of multidisciplinary cooperative groups (chiefly surgeon-pathologist), implementation of defined protocol of surgery, specimen manipulation and investigation by detached specialists lead to benefit consequences for further management and treatment of the patients with colorectal cancer.
