An experiment was conducted to evaluate the effect of substituting different levels of sun-dried Irish potato peel meal (SPPM) for maize in diets of broiler chickens. Five diets in which SPPM was replaced with 0 (0SPPM), 25 (25SPPM), 50 (50SPPM), 75 (75SPPM) and 100% (100SPPM) of maize in starter and finisher diets for a 8 week period using broiler chickens were examined. A total of 300 two weeks old broilers chicks Anak 2000 were randomly allotted to five experimental diets with six pen per treatment and 10 birds chicks per pen. Body weight and feed intake of broilers, and feed conversion ratio were determined at the beginning and 56th day of the experiment respectively. On day 56, four broilers from each pen were selected and slaughtered to determine some carcass characteristics and serum biochemistry. The result of growth performance showed that 100SPPM decreased daily weight gain of chickens when compared to other SPPM levels (P

Kolza bitkisinin Samsun koşullarında yapılan iki yıllık sonuçlarına göre ortalama 41,5 gün çiçekte kaldığı, günlük nektar üretiminin 0,23 mg/çiçek/gün, nektar kuru madde düzeyinin %20,25 ve polen üretiminin 0,48 mg/çiçek/gün olduğu saptanmıştır. Samsun İlinde kolza bitkisinin, erken ilkbahar döneminde, çevrede bulunan birçok bitkinin çiçeklenmesinden önce çiçeklendiği ve başta bal arıları (Apis mellifera L.) olmak üzere pek çok tozlayıcı böceğe, nektar ve polen sağladığı belirlenmiştir. Kolza bitkisinin arıcılık açısından ekiminin yaygınlaştırılarak erken ilkbahar döneminde, bal arıları ve diğer tozlayıcı böcekler açısından elverişli bir besin kaynağı olabileceği ortaya konmuştur.

All around the world, particularly in developed countries, fresh potato consumption decreased while the consumption as fast food, snack and convenience food was increased. Potato processing industry has by-products such as cull potato, peel, pulp, and waste water. These by-products can be utilized for production of ethyl alcohol, single cell protein, microbial enzymes, lactic acid, organic fertilizer and bioethanol. The pulp obtained from the processing of potato for starch production can be considered as an energy source with starch content in animal nutrition. Recently, potato peel with the contents of bioactive compounds (chlorogenic, caffeic, gallic, protocatechuic acids) and their antioxidant and antimicrobial effects have been intensely focused on. Conversion of by-products of potato processing industry into value-added products is economically important. It was reviewed here by-products of potato processing industry and their evaluation in animal nutrition.

Bu çalışmada, Doğu Akdeniz Tarım Havzasında bazalt, serpantin ve kireçtaşı ana materyalleri üzerinde oluşmuş topraklarda gidya (% 0, 1, 2, 4) ve azot (0, 70, 140 ve 210 mg kg-1) uygulamalarının kırmızı biber bitkisi ve farklı toprak çeşitleri üzerine etkileri incelenmiştir. Araştırmada, vejetatif gelişim bakımından gidya uygulamalarında bitki ağırlıklarındaki artış istatistiksel olarak önemli bulunmuştur. Ancak, gidya uygulamalarının meyve verimi üzerine önemli bir etkisi gözlemlenmemiştir. Diğer yandan, 140 mg kg-1 ve 210 mg kg-1 azot dozlarında bitki ve meyve ağırlıklarında önemli oranda artışlar görülmüştür. Farklı topraklarda yetiştirilen kırmızı biber bitkilerindeki morfolojik değişimler bakımından en yüksek bitki boyu ve en yüksek bitki ağırlığı bazaltik topraklarda, en yüksek meyve ağırlığı serpantinli topraklarda ve en yüksek meyve sayısı kireçli topraklarda yetişen bitkilerde ölçülmüştür.

Identification and multiple antibiotic resistances of amphicillin, chloramphenicol, streptomycin and tetracycline resistant gram-negative bacteria that isolated microorganisms from Gölbaşı and Azaplı lakes (Adiyaman) were investigated in this study. Seasonally taken isolates of totally 386 bacteria in 10 different species from 7 genera were scanned against 16 antibiotics [gentamycin, imipenem, kanamycin, chloramphenicol, meropenem, nalidixic acid, nitrofurantoin, penicillin, cephalothin, cefazolin, cefpirome, ceftizoxime, cefuroxime, streptomycin, tetracycline and trimethoprim-sulphamethoxazole (Bioanalyse)] by using the disc diffusion method to determine the prevalence of multiple antibiotic resistance. Multiple antibiotic resistance of stations showed seasonal changes between 0.29 and 0.91. In generally, multiple antibiotic resistance in Golbasi and Azapli lakes were higher than the reference value and highest multiple antibiotic resistance values were obtained at summer season (3th period). When the obtained data are considered, high multiple antibiotic resistance poses a risk in terms of public health and for economically important animals.

During the prevention and treatment of cardiovascular diseases, first cause of deaths in the world, diet has a vital role. While nutrition programs for the cardiovascular health generally focus on lipids and carbohydrates, effects of proteins are not well concerned. Thus this review is written in order to examine effect of proteins, amino acids, and the other amine consisting compounds on cardiovascular system. Because of that animal or plant derived proteins have different protein composition in different foods such as dairy products, egg, meat, chicken, fish, pulse and grains, their effects on blood pressure and regulation of lipid profile are unlike. In parallel amino acids made up proteins have different effect on cardiovascular system. From this point, sulfur containing amino acids, branched chain amino acids, aromatic amino acids, arginine, ornithine, citrulline, glycine, and glutamine may affect cardiovascular system in different metabolic pathways. In this context, one carbon metabolism, synthesis of hormone, stimulation of signaling pathways and effects of intermediate and final products that formed as a result of amino acids metabolism is determined. Despite the protein and amino acids, some other amine consisting compounds in diet include trimethylamine N-oxide, heterocyclic aromatic amines, polycyclic aromatic hydrocarbons and products of Maillard reaction. These amine consisting compounds generally increase the risk for cardiovascular diseases by stimulating oxidative stress, inflammation, and formation of atherosclerotic plaque.

The results showed that the prevalence of E. coli O157 in food was 2%, and its prevalence increased in April and May.

This study was conducted to determine the effects of Bayvarol®, Fumidil-B®, Neo-Terramycin® on adult honeybee lifespan. Total twenty honeybee colonies were used and randomly divided into four groups (each group consisted of five colonies). Experimental groups: Bayvarol ®, Fumidil-B® and Neo-Terramycin® were treated to first, second and third groups, respectively. No treatment was done to forth group taken as control group. A hundred one day old worker bees were taken from each group and marked with different colors and numbered on the thorax. After the marked, all worker bees were given into the observation hive. Marked worker bees were controlled and counted daily. Statistical analysis of data was done by variance analysis method and between groups comparisons were done with Duncan's multiple range tests. Average lifespans of the first, second, third and control groups were 44.97±4.90, 46.86±6.56, 45.38±6.12 and 47.72±6.06 days, respectively. There were found statistically significant differences among average lifespan of first, second, third and control groups. This study showed that some drugs used to treat diseases and pests reasoned a negative effect on the lifespan of honeybees.
