Bangladesh Journal of Animal Science 51 (3): 98-106, 2022 Further studies are recommended with layer diets supplemented with DOP at levels higher than 10% to determine the ideal DOP dose during other production periods in various layer strains. In summary, it may be said that layer diets can be supplemented with DOP up to 10% level to improve FCR, albumen index, yolk index, yolk color and Haugh unit without compromising egg production or exterior egg quality. Among interior egg quality attributes, the albumen height, albumen index, yolk color, and Haugh unit were all considerably elevated through supplementation of 10% DOP (p 0.05). The study revealed that dietary DOP significantly decreased the feed consumption and feed conversion ratio of layers (p 0.05). The dietary treatments were control (basal diet), 5% DOP (basal diet + 5% DOP), and 10% DOP (basal diet + 10% DOP). A total of 60 layers of 25 weeks of age were segregated into three dietary treatment groups using a completely randomized design and reared up to 42 weeks. Therefore, this study was carried out to assess the dietary effect of DOP on production and, internal and external egg quality characteristics of laying hens. The dried orange peel (DOP), by-product of citrus industry is a promising source of diversified bioactive ingredients with beneficial effects on health. Utilization of agricultural by-products in animal nutrition is a practice as old as the domestication of animals. However, evidence for fish, white meat, and eggs and the CRC risk were not as strong. In conclusion, a high consumption of total dairy products was associated with a lower CRC risk. The association between white meat and egg intake and CRC risk was low and based on a small number of studies thus, these findings should be interpreted with caution. Fish consumption, overall and by subtypes (oily or non-oily and fresh or canned), showed a mild inverse association with CRC risk. Less strong effects associated with the consumption of any subtype of dairy product were observed. The studies showed a consistent significant decrease in CRC risk, overall and by subsites, associated with a high consumption of total dairy products.
A total of fourteen cohort studies and seven case–control studies comprising a total of >60,000 cases were included. For this systematic review, we searched the PubMed database for the last five years.
We aimed to examine the recent available evidence from observational studies about the association between these food groups’ intake and CRC risk. There is limited evidence to support the relationship between the consumption of animal-source foods other than red meat and processed meat and colorectal cancer (CRC) risk. From farm to consumer, the study underlines the importance of encouraging eggshell bacterial contamination prevention strategies. Salmonella bacteria were isolated from eggshell samples at the Benghazi suburbs markets (sector E) (7.0 % from isolated samples). and Salmonella Sp.).our results showed that the mean total number of aerobic bacteria, coliform bacteria, and Staphylococcus aureus bacteria were 4.2 X 10 4, 3.9 X 10 5, 4.4 X 10 5 CFU / egg respectively. coli, Enterobacter sp., Klebsiella sp., Proteus sp., and Citrobacter sp., and 20 % are from the genera (Streptococcus sp., Pseudomonas sp.
According to this study, 80 % of pollutants are from the Enterobacteriaceae family, which includes E. The results showed significant differences (P < 0.05) between the sectors. The eggs were bought from several stores in each sector randomly, where twenty samples were collected (four from each sector) with three random replications each. Samples collected from the markets of Benghazi city, which were divided into five sectors (Bouhdima (A), Al-Laithi (B), Hay-Al-Salam region (C), Twenty Street (D), Suburbs of Benghazi (E)). This study aimed to conduct a microbial survey of the table eggs (eggshells) sold in the markets of Benghazi city and to identify some pathogenic bacteria.
