Öğe Correlations Among Chick Hatching Weight, Egg Weight and Egg Weight Loss During Preincubation Storage Period in Japanese Quail (Coturnix coturnix japonica)(MEDWELL ONLINE, 2009) Dere, Suleyman; Caglayan, Tamer; Garip, Mustafa; Inal, SerefThis study was carried out to investigate, the relationships among chick hatching weight, egg weight and egg weight loss during preincubation storage period in Japanese quail. Correlation coefficients between chick hatching weight and egg weight, egg weight loss during 4 days preincubation period were determined as 0.47 (p<0.01) and 0.36 (p<0.01). Highly positive correlations among egg weight loss groups were determined (P<0.01).Öğe Cost optimization of feed mixes by genetic algorithms(ELSEVIER SCI LTD, 2009) Sahman, M. Akif; Cunkas, Mehmet; Inal, Seref; Inal, Fatma; Coskun, Behic; Taskiran, UgurThe cost optimization is a key element to determine the least-cost feed mixture according to animals' nutrient requirements and the effective use of the sources. In this paper, the cost optimization of feeds is performed by genetic algorithm, considering the growing style and type, age, nutritional requirement and feedstuff costs for poultry and different types of animals. The proposed method is compared with linear programming approach to measure its performance. The obtained results show that Genetic algorithms could be applicable to the cost optimization of the feed mixtures. In addition, a software program is developed by using Delphi environment. which provides flexible, extensible and user-friendly framework for tuning the heuristic relevant parameters and improving the solution quality.

For this purpose, an image capture arrangement was established in a dairy cattle farm. BMs including wither height (WH), hip height (HH), body length (BL), hip width (HW), plus the LWs of cows were first determined manually, by direct measurement. Then the digital photos of cows were taken from different directions synchronously and analyzed by IA software to calculate WH, HH, BL and HW of each cow. After comparing the BMs obtained by IA with the manual measurements, the accuracy was determined as 97.72% for WH, 98.00% for HH, 97.89% for BL and 95.25% for HW. The LW estimation using BMs was then performed by the aid of the regression equations, and the correlation coefficient between the estimated and real (manual) LW values obtained by weighing was calculated as 0.9787, which indicates the IA method is appropriate for LW estimation of Holstein cows.

Totally 5015 eggs data obtained from Japanese quail, in factorial design trial (2x2x4x10), was analysed by General Linear Method (GLM) by using 4 way analysis of variance (10-11 and 14-15 degrees C egg storage temperature, 3 and 6 months of parentage; 10, 10-11, 11-12, >12 g egg weights and 0-9 days egg storage length factors). Inspecting GLM results, differences among fertility averages was statistically significant for egg weight (p = 0.0001), egg storage temperature (p = 0.007) and storage length (p = 0.018) factors and was not statistically significant for parent age factor. Differences among hatchability averages was statistically significant for egg weight (p = 0.005), egg storage temperature (p = 0.0001) and was not statistically significant for storage length and parent age factors.Öğe A fuzzy rule-based system for predicting the live weight of Holstein cows whose body dimensions were determined by image analysis(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2011) Tasdemir, Sakir; Urkmez, Abdullah; Inal, SerefThe aim of this study was to determine the body measurement of Holstein cows through image analysis (IA) and to estimate their live weight (LW) by means of a fuzzy rule-based model using the body measurements. For this purpose, a photography environment was established at a dairy cattle farm where a large number of cows were kept. First, digital photographs of each animal were synchronously taken from different directions with Canon EOS 400D cameras. At the same time, body dimensions, namely wither height (WH), hip height (HH), body length (BL), and hip width (NW), of the cows were manually measured using a laser meter and measuring stick. The LWs of the cows were found with a weighing scale and the data were automatically saved on a computer. In the second stage, the photos were analyzed by IA software developed in the Delphi programming language and body measurements were computed. Manually measured values were very close to IA results. Finally, a fuzzy system was developed by using these body measurements. This fuzzy system was developed by using MATLAB software. Weights that were estimated with the developed knowledge-based system were compared with those found by the platform scale. The correlation coefficient was calculated (r = 0.99). There was a statistically meaningful relationship between the compared data. The developed system can be used confidently, and the system on which the experiments were performed can be modeled successfully.
