Objective: The aim of this study was to determine the effects of shape index on internal and external egg quality traits and the relationship between shape index and egg quality traits in Partridges (Alectoris chukar). Materials and Methods: In this study, 155 eggs obtained from partridges raised in cages and approximately 42 weeks of age were used. Eggs were divided into three groups based on their shape index: ≤ 75 (59 eggs), < 76 - 77 > (50 eggs), and ≥ 78 (46 eggs). Each egg was individually numbered and weighed. Measurements were then made using a digital caliper at the points where the long and short axes are the largest. Literature data was used to determine other egg quality traits. The data were subjected to the GLM procedure in the SPSS 21. package program, and correlation analysis was performed to determine the relationship between the variables. Results: While shape index had no effect on eggshell thickness and eggshell ratio from external egg quality traits, its effect on egg weight (P0.01) and eggshell weight was found to be significant (P

Ülkemizde yeni doğan kuzu ve oğlakların ölüm oranına ait istatistiksel veri bulunmamakla birlikte Tarım ve Orman Bakanlığı Milli Tarım Projesi kapsamında açıkladığı verilere göre Türkiye›de yıllık 6 milyon buzağı doğduğunu ve bunlardan 900 bininin öldüğünü (%22) bildirmektedir. Benzer durumun küçükbaş hayvanlarda da olduğu tahmin edilmektedir. Küçükbaş işletmelerinde kuzu ve oğlak ölümleri çiftliğin karlılığını, hayvan refahını ve işletme sahiplerinin motivasyonunu olumsuz yönde etkilemektedir. Tüm memeliler en çok doğuma yakın günlerde bağışıklık olarak çok savunmasızdırlar. Özellikle küçükbaşlarda toplam ölüm oranının %50'si sütten kesimden önce gerçekleşmektedir (1, 2). Yavrular, sıcak ve steril bir ortamdan, daha zorlu bir ortam olana rahim dışına geçerler. Bu ortam, özellikle doğumların ocak şubat gibi soğuk aylara denk geldiği, barınakların kalabalık ve havasız olduğu patojenlerle dolu bir ortamdır. Ülkemiz ahır koşulları da özellikle göz önünde bulundurulduğunda

Fatty acid composition in milk has a vital importance in the early lactation period when lambs are milking. In this study, the change in milk fatty acid composition of Akkaraman ewe and Hair goats fed under the same conditions in the first 30 days of lactation was investigated. 10 Akkaraman ewe and 10 Hair goats were used in 2-5 parities. Ewe and goats were born in February. The animals were kept to the same feeding indoor, while experiment was going on. In addition to 1 kg of barley per animal, wheat straw was given ad libitum. Individual milk samples were taken from each animal on 0th, 1st, 3rd, 7th, 15th and 30th of lactation days. While C16:1, C18:3n3 were found more in goat milk (p

This study was carried out to determine some internal and external quality characteristics of 378 eggs collected between March and July from 42-week-old Guinea Hens (Numidae meleagris) raised by the public in Erzincan province, using mathematical formulas. Egg external quality features include shape index 73%, elongation 1.37, egg surface area 55.65 cm2, egg volume 40.39 cm3, shell thickness 0.28 mm, shell weight 3.19 g, number of pores-1 6686.05, number of pores-2 5156.10, number of pores- 3 5043.33 pieces, pore density-1 120.22 pore number/cm2, pore density-2 92.62 pore number/cm2, pore density-3 90.52 pore number/cm2; The yolk weight and white weight of the egg were determined as 6.02 g and 30.89 g, from the egg internal quality characteristics. As a result, in this study, yolk weight, shell weight and shell thickness values of egg internal and external quality characteristics calculated using mathematical formulas based on egg weight without spoiling the egg integrity were found to be lower than the values in some studies determined by measurement, while the white weight value was found to be higher.
