Öğe CANONICAL CORRELATION ANALYSIS FOR ESTIMATION OF RELATIONSHIPS BETWEEN SOME TRAITS MEASURED AT WEANING TIME AND SIX-MONTH AGE IN MERINO LAMBS(SCIENTIFIC ISSUES NATL CENTRE AGRARIAN SCIENCES, 2011) Sahin, M.; Cankaya, S.; Ceyhan, A.In this study, canonical correlation analysis was applied to estimate the relationship between six different morphologic traits (X set - at weaning; height at withers (HW), chest depth (CD), chest width (CW), chest girth (CG) and rump width (CD)) measured at weaning and morphological traits of the six-month age (Y set - at six-month age; height at withers (HW_6), chest depth (CD_6), chest width (CW_6), chest girth (CG_6) and rump width (RW_6)) measured from 72 lambs of merino, at Marmara Animal Breeding Research Institute. First two of estimated six different canonical correlation coefficients (CCC) between the pairs of canonical variables were found significant (0.717, 0.587, P<0.05). The results obtained from canonical correlation analysis indicated that chest girth and live weight had largest contribution for the explanatory capacity of canonical variables estimated from the morphologic traits of the lambs at the weaning when compared with other body measurements, while height weight and live weight had largest contribution for the explanatory capacity of canonical variables estimated from the morphological traits of the six-month age when compared with other body measurements. The results of this study showed that chest girth and live weight measured at weaning can be used as early selection criteria for genetic improvement in merino lambs.Öğe Canonical correlation analysis for estimation of relationships between some traits measured at weaning time and six-month age in merino lambs(2011) Sahin, M.; Cankaya, S.; Ceyhan, A.In this study, canonical correlation analysis was applied to estimate the relationship between six different morphologic traits (X set - at weaning; height at withers (HW), chest depth (CD), chest width (CW), chest girth (CG) and rump width (CD)) measured at weaning and morphological traits of the six-month age (Y set - at sixmonth age; height at withers (HW_6), chest depth (CD_6), chest width (CW_6), chest girth (CG_6) and rump width (RW_6)) measured from 72 lambs of merino, at Marmara Animal Breeding Research Institute.

U.; Avci, M.; Hasan, M. U.; Tanrikulu, M. M.The study aimed to evaluate the carcass trait, meat quality and fatty acid profile of Awassi lambs under cultivated pasture fattening with a concentrated feed (CPF) and intensive fattening (IF) system. A total of 76 male Awassi lambs ( 36 lambs in the CPF group and 40 in the IF group, 85 days average age) were distributed in complete random design into two experimental groups. The final body weight was lower, but the average daily gain was higher for the lambs on the CPF compared to the lambs on the IF system. There were no significant differences (p>0.05) between CPF and IF system for dressing percentage (50.31 and 51.51%) and shrinkage loss (3.45 and 2.50%), pelvic limb (34.9 and 30.3%), thoracic limb (20.8 and 18.3%), flank (9.4 and 7.6%), neck (4.4 and 5.9%), and LTL section area (15.6 and 13.0 cm(2)), except for ribs (25.0 and 33.7%), which were higher in the intensive system. Also, meat pH and color value were not changed by the fattening systems. The fatty acid profile of the longissimus thoracis et lumborum muscles was assessed. The significant differences between groups were noted in margaric (1.00 and 1.80), heptadecenoic (0.51 and 0.99), eicosenoic (80.14 and 0.20), and linolenic fatty acids (0.21 and 0,19). In conclusion, the results of this study imply that carcass traits and meat quality were similar between CPF and IF systems in Awassi male lambs.Öğe EFFECT OF ESSENTIAL OIL COMBINATION ON PERFORMANCE, MILK COMPOSITION, BLOOD PARAMETERS AND PREGNANCY RATE IN EARLY LACTATING DAIRY COWS DURING HEAT EXPOSURE(PAKISTAN AGRICULTURAL SCIENTISTS FORUM, 2012) Serbester, U.; Cinar, M.; Ceyhan, A.; Erdem, H.; Gorgulu, M.; Kutlu, H. R.; Cardozo, P. W.The objective of this study was to determine effect of an essential oil combination (EOC), which contained cinnamaldehyde and diallyl disulfide on performance, milk composition, blood parameters and pregnancy rate of early lactating dairy cows during heat exposure. Twenty five Holstein cows (days in milk= 37.4 +/- 3.09) were assigned to one of two treatment groups: a Control (n=12) and EOC fed (n=13). Cows were fed a total mixed ration comprising concentrate and silage of common vetch with triticale. The concentrate differed only in the supplementation of EOC at 25 mg/kg concentrate (as fed basis). The experiment lasted 11 weeks. Dry matter intake (DMI) and milk production were measured daily while milk samples were taken twice a week. Blood samples were collected weekly, and ultrasonography was performed at 29 d and 42 d post TAI to determine pregnancy rate. Average of ambient temperature, relative humidity and temperature-humidity index (THI) were 25.9 degrees C, 73.4% and 76.8, respectively. The EOC supplementation had no effect (P> 0.05) on performance, milk composition and pregnancy rate. The EOC, however, increased (P< 0.01) insulin concentration, and tended to decrease (P= 0.074) serum total cholesterol concentration, and increase (P= 0.097) NEFA concentration. In conclusion, EOC supplementation in diets of early lactating dairy cows during heat exposure did not affect milk yield and composition, and pregnancy rate. The increase of insulin and reduction of total cholesterol observed in EOC group needs to be confirmed with further research.Öğe Effect of essential oil combination on performance, milk composition, blood parameters and pregnancy rate in early lactating dairy cows during heat exposure(2012) Serbester, U.; Çinar, M.; Ceyhan, A.; Erdem, H.; Görgülü, M.; Kutlu, H.R.; Çelik, L.

Totally, 80 primiparous Hair goats were divided into four groups (n=20 in each) according to the body condition scores of the animals. The animals in groups were treated as follows; first group (Ovsynch), GnRH on day 0, PGF2? on day 7 and GnRH on day 9; second group (2PG-G), PGF2? on day 0, PGF2? on day 7 and GnRH on day 9; third group (PG-G), PGF2? on day 7 and GnRH on day 9; fourth group (G), GnRH on day 9. Bucks were included into the groups on day 10-14 and insemination was performed during standing heat. Blood samples were collected to determine possible embryonic losses on day 21 for further analysis of serum progesterone concentrations. Transabdominal ultrasonography was performed to detect pregnancy on day 40-45. It was determined that in Ovsynch, 2PG-G, PG-G and G groups, estrous rate was 100%, 95%, 95% and 85%; pregnancy rate was 85%, 95%, 95% and 85%; kidding rate was 100%, 78.9%, 94.7% and 88.2%; twinning rate was 41.2%, 40%, 22.2%, 20%; litter size was 1.41, 1.40, 1.22, 1.20, respectively. However, these parameters did not show any significant difference between groups (P> 0.05). In conclusion, it is suggested that all treatment procedures may be used for estrous synchronization in Hair goats during breeding season due to the satisfactory results. © 2017, Pakistan Agricultural Scientists Forum.

The effect of inbreeding on BW, WW90, and LSR traits was studied by analysis of variance technique and regression method. Inbreeding had a significant effect on BW and the regression coefficient of inbreeding on BW was -0.0245+/-0.0076 kg (P<0.01). The mean level of inbreeding (F) of all animals overall years was 2.25% for lambs. The inbred lambs rate was 17.7%. The coefficient of inbreeding ranged from 6.25% to 25.0% and average was 12.68% for birth weight in inbred lambs. Inbreeding weren't a significant effect on weaning weight at 90 days of age and lamb survival rate. It was concluded that inbreeding showed deleterious effects on birth weight and had a no effect on lamb's weaning weight and survival rate.Öğe Effect of inbreeding on preweaning growth traits and survival rate in Sakiz sheep(2011) Ceyhan, A.; Kaygisiz, A.; Sezenler, T.The objective of this study was to estimate the effect of inbreeding on birth weight (BW), weaning weight (WW90), and lamb survival rate (LSR) in Saki{dotless}z sheep.

The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an increasing earth's surface temperature. Global warming occurs as a result of gases emitted by humans into the atmosphere, creating a greenhouse effect. The livestock sector contributes between 25 and 40% of anthropogenic methane emissions. Human-derived animal production contributes to global warming by producing 9% of CO2 emissions, 35-40% of CH4, and 65% of N2O gas emissions. Carbon footprint is a measure of the damage that human activities cause to the environment in terms of the amount of GHGs produced as a unit of CO2. The most common method used in carbon footprint calculations is the Tier 1-2-3 approach developed by the intergovernmental panel on climate change (IPCC). In this study, the carbon footprint of a dairy sheep farm in Nigde province was calculated using Tier 1 method to determine global warming potential. The carbon footprint of this farm from both sources like N2O and CH4 was 85535.2 CO(2)eq year(-1). The estimation of GHGs is very obligatory to evaluate global warming stress and avoidance from some fatal diseases.Öğe The Investigation of SNP in SOCS2 Gene Associated with Mastitis Resistance, Milk Composition, and Quality in Awassi Sheep.(Springer, 2022) Ul Hasan, M.; Ceyhan, A.[Abstract Not Available]Öğe THE RELATIONSHIP BETWEEN BODY WEIGHT AND BODY CONDITION SCORE SOME INDIGENOUS SHEEP BREEDS IN TURKEY(PAKISTIAN AGRICULTURAL SCIENTISTS FORUM, 2011) Sezenler, T.; Ozder, M.; Yildirir, M.; Ceyhan, A.; Yuksel, M. A.This study was carried out on Kivircik, Sakiz and Gokceada sheep bred at Marmara Livestock Research Institute. A total of 156 heads sheep from different age groups were used in the study. The relationships between Body Condition Scores (BCS) and Body Weights (BW) have been investigated in three different physiological periods such as breeding, lambing and weaning period of indigenous sheep breeds in Turkey. As a result of the analyses conducted, the relationship between body condition score and body weight were found to be BW = 28.716+6.962* BCS; BW = 39.977+6.771* BCS; BW = 33.444+7.074* BCS for the breeding, lambing and weaning periods respectively. Similarly, correlations (r) between them were found to be 0.817, 0.731, 0.746 respectively (P<0.01). The regression coefficients of BCS on BW were 6.962 kg, 6.771 kg, 7.074 kg at breeding, lambing, weaning respectively and also significant (P<0.01). The findings demonstrate that body condition score is a good indicator of changes in body weights in Kivircik, Sakiz and Gokceada indigenous sheep breeds and will assist sheep breeders with regard to the feeding program to be applied particularly before the breeding season.Öğe The relationship between body weight and body condition score some indigenous sheep breeds in Turkey(2011) Sezenler, T.; Özder, M.; Yildirir, M.; Ceyhan, A.; Yüksel, M.A.This study was carried out on Kivircik, Sakiz and Gokceada sheep bred at Marmara Livestock Research Institute.
