  • Determination of Some Growth Traits in Morkaraman Lambs

    • Authors: Muhammet Selçuk ŞAHİN; Sinan KOPUZLU
      Abstract: In this study, it was aimed to determine the growth traits of Morkaraman lambs raised in breeder conditions born in 2018-2019 in Erzurum province. This study was conducted to determine the growth traits such as birth weight (BW), live weight at the beginning of the grazing period (LWBGP), live weight at the grazing period (LWGP), live weight at the end of the grazing period (LWEGP), daily live weight gain from the birth to the beginning of the grazing period (DLWGBBGP), daily live weight gains during the grazing period (DLWGGP) and daily live weight gain from the birth to the end of the grazing period (DLWGEGP) of 1032 Morkaraman lambs. It was, also, planned to reveal the differences between these performance characteristics. The effects of some environmental factors such as sex, lambing type, year, and ewe age on these traits were examined. The means of BW, LWBGP, LWGP, LWEGP, DLWGBBGP, DLWGGP and DLWGEGP of the lambs were found as 3,67kg, 24,82 kg, 13,76 kg, 38,25 kg, 226,16 g, 141,77 g, and 192,94 g, respectively. According to the statistical analysis results; not only the effect of years, sex, lambing type and ewe age on LWEGP were determined to be significant (P<0,01). To conclude, the local and pasture conditions in Erzurum province. Some growth performances of Morkaraman lambs were determined. Based on performance values such as live weight and daily live weight gains, the lambs can reach the desired slaughter weight up to the end of the grazing period.

  • Investigation of Colostrum Quality in Different Bovine Breeds

    • Authors: Jale METİN KIYICI; Berna SEVİŞOĞLU
      Abstract: In this study, it was aimed to compare and determine the quality of colostrum by brix refractometer in the postpartum period in 4 different cattle breeds (Holstein, Jersey, Simental, Danish Red). In the study were used 107 colostrum samples that from 4 different breeds of cows, 56 Holstein, 29 Jersey, 12 Simmental and 10 Danish Red. Colostrum brix refractometer was used to determine the colostrum quality and the results were expressed as % ratios. In the study, the differences between breeds in terms of colostrum brix value were statistically significant (P<0.05). According to the breeds, the highest colostrum brix value was determined in the Simmental breed (27.8 %), followed by the Danish Red (27.5 %), the Holstein (27.2 %) and the Jersey breed (26.0 %), respectively. In the study, the effect of lactation number, dry period lenght, calf birth weight and calving season on colostrum brix value was not statistically significant (P>0.05). In the study, it was concluded that the colostrum brix value differed between breeds, but the effect of other factors examined on this parameter was not significant.

  • A Study on Relationships Between Different Udder Measurements and Milk
           Yield Characteristics in Awassi Sheep

    • Authors: Pınar KUTAN; Mahmut KESKİN
      Abstract: This study was carried out to determine the phenotypic corelations between different udder sizes and marketable milk yield in Awassi sheep. The animal material of the study consisted of primiparous vs multiparous sheep. Marketable milk yield and udder sizes were determined after weaning in sheep. The correlations between the examined features were calculated with the SPSS package program. At the end of the study, positive and significant (P<0.05 and P<0.01) correlations were calculated between teat length, teat circumference and udder width over the teat, and marketable milk yield. It has been evaluated that these correlations can be used in the selection of the breeding stocks.

  • Investigation on the Expression Profile of Immune-Related Genes in
           Response to Lipopolysaccharide and Lipoteichoic Acid in Alveolar
           Macrophages of Akkaraman and Romanov Lambs

    • Authors: Ahmed Qasim NAJİ; Md Mahmodul Hasan SOHEL, Saif Adil Abbood AL-JANABİ, Ghulam Asghar SAJİD, Mehmet Ulaş ÇINAR
      Abstract: The alveolar macrophages (AMs) are frontier of defense against foreign materials that initiate immune response in lungs. Knowledge of the expression dynamics of major immune-related genes in the alveolar macrophages in response to lipopolysaccharide (LPS) and lipoteichoic acid (LTA) challenge can help to understand disease mechanism involved in several respiratory diseases. The aim of this study was to investigate the mRNA expression of selected immune-related genes in response to lipopolysaccharide (LPS) and lipoteichoic acid (LTA) challenge in sheep alveolar macrophages in vivo. Results revealed that Romanov lambs exhibited higher mRNA expression of TLR2, TLR4, NF-ĸβ, TNFα, IL-1β, IL-6, IL-8, and IL-10 genes as compared to Akkaraman lambs along with the control of all treatments. Moreover, the expression of TLR2, TLR4, NF-ĸβ, TNFα, IL-1β, IL-6, IL-8, and IL-10 genes was higher in combine treatment of LPS and LTA as compared to separate treatments of LPS and LTA in both breeds. The results showed that the mRNA expression of immune-related genes was significantly increased in the sheep AMs in response to LPS and LTA treatment whereas a synergistic effect was observed in LPS+LTS treatment. Also, breed comparison showed that the native Akkaraman was more resistant to disease compared to exotic Romanov.

  • Current Situation of Cattle and Small Ruminant breeding in Aydın

    • Authors: Semih SEVİM
      Abstract: This study examines the current situation of cattle and small ruminant breeding in Aydın and reveals its importance to Aydın province. Given the last 10 years of several animals (2012-2021) in our country, it is seen that our number of sheep has increased from 27.4 million to 45.1 million, a number ogoatsat from 8.3 million to 12.3 million head number of cattle form 14 million to 17.9 million head. The total production of milk was 22.960.377 tons, fleece and mohair, 85.915 tons and 468 tons respectively. According to data from 2021, our beef production was 1 million 460 thousand tons, our sheep meat production was 385 thousand tons, our goat meat production was 94 thousand tons. In Turkey, the annual consumption of beef is 13.12 kg per person, the consumption of small meat is 5.39 kg and the consumption of chicken meat is 20.65 kg. In Aydın province, the ratio of cultural breeds in cattle as a whole is 74.62% of hybrid breeds 17.70 and the ratio of domestic breeds is 7.68%. The cultural breed of Aydın province contains 4% of its presence in Turkey. It is classified as 364.581 heads in 4 provinces. In Aydın Province, the number of dairy farming enterprises producing milk with 1-5 head of animals is 17.063 and the number of beef cattle enterprises with 1-5 head of animals is 1.545. Aydın province ranks second after İzmir in the Aegean region with total milk production of 566.298,09 tons. In terms of average milk yield per milked cow (Culture), Aydın province ranks fourth in the Aegean region with 3.965 kg. The average sheep milk yield is 83.60 kg, average goat milk is 106.98 kg in Aydın province. As a result, Aydın province plays a significant role in the agricultural sector of the country.
