AbstractThe aim of the study was to assess the quality of carcasses and meat from selected native breeds and breeding lines of hens after using them for laying eggs in terms of their usefulness as raw material in traditional old polish cuisine. hens included in the programme for the protection of genetic resources were the object of this study. they belonged to the following breeds/breeding lines: greenleg partridge (Z-11), rhode Island red (r-11), new hampshire (n-11) and Barred rock (WJ-44) – 30 hens from each line. the hens were kept in a closed hen house under standard raising conditions. eight hens were selected from 56-week-old hens of each line which were subjected to analysis after being slaughtered. as a result of the research conducted, it was found that:– Among the hens under study, heavier layers, i.e. Barred rock (WJ-44), new hampshire (n-11) and rhode Island red (r-11), which are characterized by good muscling and dressing percentage similar to that of broiler chickens, proved to be most suitable for use as meat.– The meat from WJ-44 hens contained most cholesterol and least protein, and the meat from Z-11 birds had the least fat compared to the other lines.– At the end of the laying period, meat and broth from WJ-44, n-11 and r-11 hens obtained better sensory scores than those from the carcasses of Z-11 hens, which makes them an attractive raw material for traditional polish cuisine.

Methicillin Resistant

Multiresistant and especially Methicillin-Resistant Staphylococcus aureus (MRSA) poses a serious public health problem that requires their immediate identification and antibiotic resistance characteristics. In order to determine antibiotic resistance S. aureus poultry and bovine origin, 8840 samples were collected from slaughterhouses in the northern region of Algeria between years 2009 and 2014. 8375 samples were from an avian origin (1875 from laying hens and 6500 from broiler chickens) and the rest was from bovine origin. Bacteriological isolation and identification were made by classical culture method and antibiotic resistance patterns were determined by disc diffusion test. The prevalence of S. aureus was 42% in laying hens, 12% in broilers, and 55% in bovine samples. The prevalence of MRSA was 57%, 50%, and 31% in laying hens, broiler chickens, and bovine, respectively. While MRSA strains isolated from poultry showed cross-resistance to aminoglycosides, fluoroquinolones, macrolides, sulphonamides, and cyclins, those isolated from bovine also revealed similar multiresistance except for sulphonamide. This high percentage of methicillin resistance and multidrug resistance in S. aureus poultry and bovine origin may have importance for human health and curing of human infections.

Microbial Phytase

This research aimed to determine effects of phytase in cottonseed meal (CM) and rice husk (RH) based diets on true phosphorus digestibility (TPD) by broiler chickens. Two studies were conducted with 576 one-day-old broiler chickens using regression analysis to determine the TPD in these diets and the response to phytase supplementation. Six semi-purified diets were formulated to contain 150 g, 300 g, and 450 g each of CM/kg (experiment 1) and RH/kg (experiment 2) with phytase supplied at 0 and 1000 units/kg. Titanium dioxide was added to the diets at the rate of 5 g/kg as an indigestible maker. A total of 288 broiler chickens in each study were weighed and allotted to the six diets with six replicates of eight birds in a randomized complete block design. The birds were fed the experimental diets until day 26 post hatch. The coefficients of true phosphorus retention (TPR) were 0.8 for CM and 0.78 for RH without phytase; 0.93 for CM and 0.92 for RH with phytase. True phosphorus digestibility was 0.82 for CM and 0.75 for RH without phytase; and 0.95 for CM and 0.92 for RH with phytase. Phytase supplementation resulted in 13.27 and 17.94 % increases in TPD; and 12.29 and 13.61 % increases in TPR by birds fed the CM and RH diets, respectively. Phytase supplementation of CM and RH based diets increased TPD and improved total TPR and true ileal phosphorus digestibility in broiler chickens.
