Abstract: Yağ asitlerinin insan sağlığı açısından hastalıkları önleyici ve tedavi edici özelliği vardır. Ayrıca süt ve süt ürünlerinde kaliteyi etkileyen önemli bir parametredir. Dolayısıyla hayvansal ürünlerde yağ asidi kompozisyonun belirlenmesi büyük önem taşımaktadır. Bu araştırma Akkaraman (Akk), Bafra (Baf) ve Bafra x Akkaraman (F1) koyunlarda süt yağ asidi kompozisyonunun belirlenmesi amacıyla yapılmıştır. Yağ asidi kompozisyonu, her genotipten rastgele seçilen 12 koyundan laktasyonun başlangıç, orta ve son dönem… Show more

Decision trees are data mining algorithms that make interpreting the cause-effect relationship or classification between features with visual diagrams easy and do not require parametric assumptions. The aim of this study is to classify different sheep breeds raised in Turkey according to their origin and tail structure characteristics using a decision tree algorithm. It has been seen that the CART (Classification and Regression Trees) algorithm is sufficient for the classification of sheep breeds by obtaining low-risk values. According to the results of the study, it is seen that domestic sheep breeds are distributed to Eastern Anatolia, Mediterranean, Black Sea, and Central Anatolia Regions and imported breeds are distributed to all regions of Türkiye. The total population of these breeds was determined as 43.889.918 heads. As it can be understood, the Akkaraman breed ranks first with a rate of 40.88% of the total sheep stock. Next comes the Morkaraman breed with a rate of 11.68%. Thirdly, the most cultivated breed is Kıvırcık, whose rate is 8.82%. Merino sheep comes in fourth place with 8.43%. Awassi sheep are among the most common breeds in the fifth place. Hereby the distribution of sheep breeds in Türkiye has also been revealed and the distribution of breeds according to environmental conditions has been determined. The decision tree model generated using the CART algorithm for the distribution of sheep breeds in Turkey based on tail structures has been found to have a value (0.47). The proportion of sheep with a thin tail structure is 52.2%, while those with a semi-fatty tail structure are 17.5%, and those with a fatty tail structure are 30.2%. It has been determined that sheep breeds with thin tails are more commonly raised in Turkey. In the study, a decision tree model was also created using the CART algorithm to analyze the distribution of sheep populations in regions based on their origin, and it was found to have a value (0.26) with an accuracy rate of 74%. According to the research, 73.9% of sheep are domestic, while 26.1% are imported. When examining the distribution of origin by region, the region with the least number of imported sheep is Eastern Anatolia, while the highest proportions are found in the Mediterranean and Black Sea regions. The region with the lowest proportion of domestic sheep is the Mediterranean and Black Sea (70.4%), whereas the highest proportion is in the Eastern Anatolia region (82.6%).

Whey is a dairy product that was formed as a result of cheese making and is considered a dairy residue or by–product. Making the best use of whey is important in terms of protecting the environment, preventing economic losses and gaining added value. The aim of this study was to obtain butter, an economical and healthy product from whey, and to compare butter obtained from milk in terms of fatty acid profile, color values and some chemical quality criteria. In addition, it is to determine the butter yield of whey. For this purpose, butter was produced from raw cow's milk and from whey in accordance with the technology. Dry matter (%), ash (%), fat (%), pH, titration acidity and refractive index to determine chemical quality, color analysis with digital colorimeter to determine color values and fatty acid analysis with GC–FID to determine fatty acid profile done. It was determined that butters produced from milk and whey were not statistically different (P>0.05) in terms of other chemical properties except the fat content they contain. In terms of color values and fatty acid profiles, it was determined that butter produced from milk and whey cheese had similar values. In the butter samples, palmitic and myristic acids were the most common fatty acids. The butter yield of whey was determined as 405 g butter·100 L-1. Thus, it was concluded that whey, which is an important milk residue, can be used as an alternative raw material in the production of butter and that producing butter from whey will contribute to the economy and protection of the environment.
