In this study, the effect of STAT5A gene was investigated on milk yield and components (fat, protein) in Jersey cows. Because, this gene is a member of the signal transducers and activators of transcription the factor (STAT) family and thought to be the impact on milk yield and components. As a material in the research, 100 Jersey cows raised in Samsun Karakoy State Farm were used. Milk samples were collected 12 times with one month intervals after calving, and these samples were performed by ultrasonic milk analyzer for milk fat and protein content. In addition, test day milk yield (TDMY) of each cow were also recorded in the control days. C/G polymorphism with PCR-RFLP method result in DNA isolation from blood samples taken from cows was determined at 8.exon at position 12195. Genotype distribution was detected as 69% CC, 28% CG and 3% GG. Allele frequencies were found as 0.83 for the C allele and 0.17 for G allele. As a result of the polymorphism identified in STAT5A gene, statistically no difference were detected among genotypes for TDMY, 305 day milk yield (305 DMY), milk fat and protein rates and milk fat and protein yield. As a result, no significant differences were found between the milk yield and compositions association with STAT5A

The aim of this study is to determine the factor effective in determining the hardness of Caterina, Suidring, Royal Glory and Tirrenia peach types using meta analysis. In the study, the impact force (Fi) and the contact time (tc) were detected and the impulse values (I) that are expressed as independent variable in the area under the curve were calculated in the measurements performed using the technique of a low-mass lateral impactor multiplicated with peach. Using the theory of elasticity, the independent variables were determined as Fmax (maximum impact force), contact time (tmax), Fmax/tmax, 1/tmax, 1/tmax2,5, Fmax/tmax 1.25 and Fmax2.5 parameters. The correlation coefficient values showing the relationship between these parameters and the dependent variable Magness-Taylor force (MT) were calculated and were combined with meta-analysis by using the Hunter-Schmid and Fisher’s Z methods. The Cohen’s classification criterion was used in evaluating the resulting mean effect size (combined correlation value) and in determining its direction. As a result of the meta-analysis, the mean effect size according to Hunter-Schmid method was found 0.436 (0.371-0.497) positively directed in 95% confidence interval, while it was found 0.468 (0.390-0.545) according to Fisher’s Z method. The effect sizes in both methods were determined “mid-level” according to the Cohen’s classification. When the significance level of the studies was analyzed with the Z test, all of the ones that taken into the meta analysis has been found statistically significant. As a result of the meta analysis in this study evaluating the relationship of peach types with the fruit hardness, the mean effect size has been found to reach “strong level”. Consequently, “maximum shock acceleration” was found to be a more effective factor comparing to the other factors in determining the the fruit hardness according to the results of meta analysis applied in both methods.

Nowadays, meeting adequately nutrient requirements of animal is a major problem due to cost of feed. This situation results in the feed manufacturers to search alternative feed source in order to provide more economical feeding in animal nutrition. In Turkey known as a paradise of olive, a number of substances were discharged to the environment during olive processing. After pressing of olive, the olive remains such as olive cake and black water cause off-odour, groundwater pollution, visual pollution and formation of a fly in environment. Among these by-products, olive cake has been extensively used as fuel. However, olive cake and black water can be used as alternative animal feed due to their high nutrient contents. In this review, the importance and use of the olive cake and black water in animal nutrition will be discussed.

Rhizobia are able to increase yield of non-leguminous species through production of phyto-stimulating substances. This study aimed to evaluate the inoculation effect of rhizobia UFRGS Lc348 and VP16 on millet and Sudan grass yield and germination, and verify the enrichment effect of culture medium with tryptophan, which leads on the rhizobium/plant interaction. Experiments in vitro and greenhouse conditions were conducted. In millet, the inoculation with VP16 grown in culture medium with or without tryptophan induces greater length of hypocotyl and epicotyl under in vitro conditions. UFRGS Lc348 treatment induces longer hypocotyls of millet under in vitro conditions. No effects were observed with the millet inoculation in greenhouse. In Sudan grass, inoculation with VP16 enriched with tryptophan increased dry matter in shoots of adult plants. In millet seedlings had achieved an increasing in elongation in vitro conditions, which could represent an adaptive advantage in the search for water and nutrients in the rhizospheric environment during the initial growth of millet. Similarly, if verified in field conditions, Sudan grass had achieved an increasing in greenhouse conditions with the inoculation of tryptophan-enriched VP16, which could be correlated with a significant gain in crop yield. Therefore, these relationships between tryptophan-enriched VP16 and Sudan grass should be verified in subsequent studies under field conditions. | Rizobios son capaces de influir en el rendimiento de las especies no leguminosas través de la producción de sustancias fitoestimulantes. El objetivo de este estudio fue el de estudiar el efecto de la inoculación de rizobios UFRGS Lc348 y VP16 sobre la germinación y el rendimiento de millo y pasto Sudán, así como verificar si el enriquecimiento del medio de cultivo con triptófano interfiere en la interacción rizobio/planta. Para este fin se llevaron a cabo experimentos in vitro y bajo condiciones de invernadero. En el experimento con millo en condiciones in vitro, la inoculación con VP16 cultivado en medio enriquecido o no enriquecido con triptófano induce una mayor extensión de hipocótilo y epicótilo. El tratamiento UFRGS Lc348 induce una mayor extensión de hipocótilo en plantas de millo. En plantas adultas de millo no hubo efecto de la inoculación. En pasto Sudán, la inoculación de VP16 enriquecida con triptófano aumentó la masa seca de las plantas adultas. Los aumentos de elongación de plántulas de millo en condiciones in vitro pueden representar una ventaja adaptativa en la búsqueda de agua y nutrientes en el ambiente rizosférico durante el crecimiento inicial del millo. De manera similar, si se verifica en condiciones de campo, el incremento de pasto Sudán observado en condiciones de invernadero con la inoculación de VP16 enriquecido con triptófano, esto puede significar una ganancia significativa en el rendimiento del cultivo. Por lo tanto, estas relaciones entre VP16 enriquecido con triptófano y pasto Sudán deben ser verificadas en estudios posteriores en condiciones de campo.

Hasan Arısoy | Zeki Bayramoğlu
Nowadays, meat consuming level is an indicator of development of countries. The reason for this is the importance of animal proteins such as meat, milk and egg in human nutrition. People in Turkey do not get enough animal protein. Increase of meat and meat related product prices is effective on this. The purpose of this study is to bring up the purchase and consume behavior of consumers. Surveys completed in urban areas around city of Ankara are used primarily. Using Main Mass Ratio Based Simple Occurrence Probability Sampling method 338 families were interviewed. Completed surveys were separated into 3 groups; high, middle, low. As a result of the research, expense for food in total income is around %34. This ratio for families with low income is %53, for families with middle income is %35 and for families with high income is %33. It is found that as income levels of consumers raised, food expenses raise as well. But it shows that as income level increases, expense ratio for food decreases. Food reliability is the most effective factor on consumers’ decision of purchase. Studies show doubts of consumers about food reliability. It is understood that legal adjustments are not applied enough. Especially tight food inspections would be positive on consumer behavior.

Ramazan İlhan Aytekin | Sevgi Çalışkan
Uniform description of developmental stages in crops improve communication among producers, researchers and others. A standardized, accurate, and easy system is needed to describe bean (Phaseolus vulgaris L.) plant development. The objective of this study was to develop and describe stages of bean plant development in a manner which is simple but accurate. The biological cycle of the bean plant is divided into two successive phases: the vegetative stage (V) and the reproductive stage (R). Vegetative stages are determined by counting the number of trifoliolate leaves (V1 to VN) on the main stem beginning above the unifoliate leaf. Reproductive stages R1 and R2 are based on flowering, R3 and R4 on pod development, R5 and R6 on seed development, and R7, R8 and R9 on maturation.
