  This study was carried out to determine some morphological characteristics of Kangal (Karabash) dogs raised by private breeders and in civil farms in countryside. Data were collected from Kirikkale province in Middle Anatolia region of Turkey. Total 50 Kangal dogs, 38 male and 12 female were examined. Data were analyzed for sex and age groups. The Duncan test was used for detecting different among groups. This study is the first study about Kangal dogs bred by shepherds at villages and rural areas. Means of the Wither Height (WH), Chest Circumference (CC), the Rump Height (RH), the Rump Length (RL), the Rump Width (RW), Body Length (BL), Chest Depth (CD), Chest Length (CL), the Front Wrist Circumference (FWC), Head Legth (HL), Head Circumference (HC), the Ear Length (EL), Distance Between Ears (DBE), Breadth of Front Chest (BFC), Body Weight (BW), Body Index (the proportion of body length and wither height) (BI), Bone Index (BI2) for Kangal (Karabash) dogs were found 75.91±0.97, 86.12±1.53, 75.92±0.99, 21.85±0.75, 19.44±0.69, 74.77±0.93, 37.62±0.81, 34.43±0.82, 16.57±0.40, 29.09±0.47, 58.14±0.96, 14.32±0.42, 19.04±0.52 and 22.41±0.73 cm, 50.77±2.05 kg, 1.20±0.03, and 0.22±0.01. Effects of sex of dog on WH, RH and HC were statistically significant (p<0.001-p<0.01), effect on sex of dog on BW and CC were statistically significant (p<0.05). There are significant differences between male and female kangal dogs for the live weight and somebody measurements. Effect of age of dogs on BI was only statistically significant (p<0.005). In conclusion, it can be said that body measurements and body weigh of Kangal dogs reared at Kirikkale province was generally slightly higher than other regions of Turkey.

  In this study, effects of environmental factors on milk yield and milk yield characteristics of Holstein cows raised at Tahirova state farm in Balikesir province of Turkey have been investigated. A total of 1302 milk records obtained between 2000 and 2007 were used in this study. As milk yield traits, lactation duration, lactation milk yield, 305 days milk yield and dry period were investigated. Effect of environmental factors on milk yield traits was analyzed by using the least square means method. The least square means for the lactation duration, lactation milk yield, 305 days milk and dry period yield were 331.74±1.55 days, 7574.39±55.22 kg, 6810.14±56.38 kg and 79.47±0.90 days, respectively. The effects of calving year on lactation duration, lactation milk yield, 305 days milk yield and dry period were much significant (p<0.01). Effect of calving season on lactation duration was significant (p<0.05). Effect calving age on lactation duration and lactation milk yield was significant (p<0.05, p<0.01). The effects parity on lactation duration, lactation milk yield, 305 days milk yield and dry period were significant (p<0.01-0.05). It can be said that Holstein cattle have quite well milk yield and are raised successfully on Tahirova state farm and under conditions of west Anatolia in Turkey. To obtain much higher milk yield in this farm, true selection for milk yield should be done and better feeding, care and management should be done.

  The aim of this study was to investigate environmental factors affecting reproductive traits of Holstein cows and heifers raised at the Tahirova state farm in province Balikesir in Turkey. Reproductive traits were investigated by using 1074 records between 2000 and 2008. The least square means of age of first breeding, age of first calving, service period, calving interval and gestation length were 523.90±6.71, 815.38±7.18, 387.69±1.60, 122.30±1.67 and 277.45±0.27 days, respectively. Effects of calving year, calving age, calving season on age of first breeding and age of first calving were statistically significant (p<0.01). The effects of calving age, calving year and calving season on calving interval were significant (p<0.01-0.05). Although, the effect of calving year on service period was non-significant (p>0.05), the effects of calving age and calving season on service period were significant (p<0.01-0.05). Effects of sex of calf, calving age, calving year and calving season on gestation length were statistically significant (p<0.01-0.05). According to these results, it can be concluded that reproductive performance of Holstein cattle reared at this farm in Balikesir province were raised more successful than state farms in other regions of Turkey. To obtain better reproductive performance, service period should be decreased, heifers should be bred at 15 months of age, oestrus detection and artificial insemination should be done at the right time and convenient manner, GnRH injections was done for cows with high milk yield.

  The purpose of this study was to estimate the trends components of 305-days milk yield in Holstein Friesian Cattle Holstein cows raised at the Ceylanpinar state farm in Turkey between 1986 and 2007 years. The phenotypic, genetic and environmental trends for 305-days milk yield were found to be 106.91, 13.42 and 93.49 kg year-1, respectively. Despite, there was a correct decision in selection environmental factors affected yield more. In this respect, continuing the improving environmental factors which is composed of maintenance, feeding, milking practices and barn is recommended.
