Lukman Oladimeji Raji | Oluwatoyin Oluwasola Ajala
This study was carried out to document ex-situ morphological and morphometric characteristics of the testis in the West African Dwarf (WAD) buck goat. For this aim, 24 post pubertal WAD buck testes were collected at the Ipata Abattoir in Ilorin, Kwara state, Nigeria. Gross morphologic results revealed that WAD testis was ellipsoidal in shape with 2 borders (free and attached), margins (medial and lateral) and similar surfaces (ventral and dorsal). The surfaces were covered by an outer tunica vaginalis and a deep tunica albuginea. Histomorphology showed the testis comprised mostly of rounded and some irregularly shaped seminiferous tubules (ST). Each ST was lined by a basement membrane and a layer of germinal epithelium with lumen filled with spermatozoa surrounded by an adluminal space. Gross morphometric results showed that there were no significant differences in the weight, length, width and height of the right and left testis. Also in the volumes of testes obtained by water displacement method and using the prolate ellipsoid formula. There was a strong correlation between the weights and volumes of testes obtained using these methods. There were significant differences between the volumes of testes obtained by using the prolate spheroid and Lambert formulae, when compared with those obtained by water displacement method respectively. But there was no significant difference in testicular volume obtained by the prolate ellipsoid formula and the water displacement method. Histomorphometric results revealed no significant differences in the seminiferous tubular diameter, seminiferous luminal diameter and germinal epithelia height of the right and left testes respectively. The morphological and morphometric data highlighted in this study would be useful in comparative regional anatomy and researches on the testis of these valuable breed of goats.

The main objective of the study is to determine the structure of seed usage of the wheat farms and development of its production in Isparta and Burdur provinces. The primary data used in this study were obtained by questionnaires in the region. Data obtained from the 150 of wheat cultivation farms belongs to the 2011 production period. The most important problems faced by farms were the low product prices and high input prices. Farmers pointed out that the development of wheat production can be provided by reducing the input costs such as; fertilizer, fuel, pesticide etc. The 97.3% of the wheat growing farms in the region make the seed dressing. About 52.7% of the interviewed enterprises are storing wheat and 74.7% of the farms are aware of the wheat varieties grown. About 52% of farms were found to be the use of certified seed. Certified seed usage rate is higher in the province of Isparta (69.3%) than Burdur. There is also a statistical difference in the use of certified seeds among the provinces. In the region, it was found that farms do not have enough information about the usage of certified seed and therefore it is necessary to transfer knowledge to the grower by the extension services.

2015
Aslı Zungur | Berker Nacak | Meltem Serdaroglu
Model system chicken emulsions were prepared by replacing 5, 10, 15 and 20 % beef fat with chicken skin. Moisture, protein, fat, ash and pH were determined in raw and heat processed emulsions. Emulsion samples were evaluated for cooking characteristics, TBA values and colour parameters (L*, a*, b*). Addition of chicken skin decreased fat content and increased moisture and protein content of emulsion samples. Chicken skin replacement significantly increased water holding capacity and cooking yield and decreased fluid release. Increasing chicken skin in formulation increased a* and b* values of emulsion samples. Therefore, adding of chicken skin instead of beef fat is useful in improving technological quality and producing low fat formulation.

Mycotoxin occurrence in foods, especially in uncontrolled produced traditional foods causes serious health problems. In this study, traditional Küp cheese samples were collected from different part of Anatolian region in Turkey (Ankara, Nevşehir and Yozgat) and analyzed to determine Aflatoxin M1 (AFM1) level. AFM1 analysis was carried out by, immunoaffinity column (IAC) clean-up and high performance liquid chromatography (HPLC) attached with fluorescence detector (FL) The level of AFM1 in all samples was in the range of 16 and 136 ng/kg which is lower than the maximum tolerance limit of the Turkish Codex Regulations (250 ng/kg). The levels of contamination indicated that more detailed and continuous monitoring is required to increase the public health conscious and reduce consumers’ exposure to AFM1.

2015
Tugay Ayasan
The poultry industry in the developing countries is facing some challenges, one of which is an increase in the cost of feed because of high prices of protein and energy sources. Moringa oleifera is a rich source of protein and crude fiber content. The crude protein (CP) content of Moringa ranges from 7.12 to 39.17%. Negligible content of tannins and other anti-nutritive compounds and offers an alternative source of protein to ruminants and non-ruminants. Although rich in nutrients such as protein and minerals, Moringa oleifera is one of those plants that have not been studied for many years. In addition, they are also faced with the problem of the development of antibiotic resistant pathogens due to unwise and excessive use of antibiotics. In this paper, feeding studies made on the Moringa oleifera used in nutrition of poultry and ruminant species have been reviewed.
