    Effect of estrus synchronization on dairy goat milk composition
    (Academic Journals, 2010) Konyali, Aynur; Ayag, Bekir Sitki; Yurdabak, Serkan
    This study was aimed to observe the effects of progesterone impregnated sponge insertion on milk yield and milk composition in dairy goats. For this reason milk samples were collected before insertion and during the treatment. Sixty four Turkish Saanen goats were used in the research. Animals were milked twice daily. Reduce in milk yield was observed. Fat content of milk decreased, while lactose content, solids-non-fat, density and pH value increased during the sponge application. Protein content was not influenced by the treatment. New experiment under controlled conditions might be planned to characterize the hormonal status of animal and their effects on milk yield and composition.

    Effects of whole and steam-flaked corn supplementation on productive performance, serum parameters, and reproductive characteristics of dairy ewes
    (Copernicus Gesellschaft Mbh, 2024) Akbag, Hande Isil; Tölü, Cemil; Savaş, Türker; Konyali, Aynur; Coskun, Baver; Yurtman, Ismail Yaman
    This study aimed to determine the effects of whole and steam-flaked corn supplementation on the feed intake, serum parameters, and reproductive performance of dairy ewes. A total of 48 ewes (at the end of their lactation period; 57 +/- 1.3 kg body weight, BW; 2.69 +/- 0.19 body condition score, BCS) were divided into three treatment groups (16 animals per group): the control group (C), which was fed with alfalfa hay and corn silage; the whole-corn group (WC), which was fed with alfalfa hay, corn silage, and whole corn; and the steam-flaked corn group (FC), which was fed with alfalfa hay, corn silage, and steam-flaked corn. The study was conducted for 15 d before ram introduction and for 30 d during the mating in the breeding season. The WC group had higher dry matter (DM), metabolizable energy (ME), and starch intake values than the FC group (P<0.0001). The BW and BCS values were increased in the groups supplemented with whole corn and steam-flaked corn (P <= 0.05). The lambing rate was higher in ewes from the WC and FC groups (P <= 0.05). Whole and steam-flaked corn supplementation did not affect the non-return ratio or litter size (P>0.05). The serum glucose concentration was similar among the groups, whereas the serum urea concentration increased with either whole or steam-flaked corn supplementation (P <= 0.05). In conclusion, whole and steam-flaked corn supplementation increased the BW, BCS, and lambing rate values in dairy ewes.

    Efficiency of the Membership of Dairy Farms in a regional cattle-breeding organization in Turkey
    (W Kohlhammer Gmbh, I A Jochen Krauss, 2009) Akturk, Duygu; Tatlidil, Fuesun; Konyali, Aynur
    The data used in this investigation were collected on the one hand from enterprises which were members of a cattle-breeding organisation in the province of Canakkale and on the other from enterprises located in this province that did not belong to any cattle breeding organization. In this study, the enterprises were compared in respect of their technical and scale-related efficiency, paying particular regard to output. Although membership resulted in significantly higher average lactation length as well as higher productive life for the cattle (P <0.05), there were no significant differences between member enterprises and non-member enterprises in respect of their technical and scale efficiency (P> 0.05). However, bigger enterprises, with more than 10 livestock units, displayed on average greater technical efficiency than smaller enterprises. The results indicated that the cattle breeding organization was not effective. Technical consultation would have an important role to play in increasing the effectiveness of the cattle breeding organization.

    Genetic diversity and population structure of Anatolian Hair goats, an ancient breed
    (Copernicus Gesellschaft Mbh, 2024) Demiray, Aylin; Gunduz, Zuhal; Ata, Nezih; Yilmaz, Onur; Cemal, Ibrahim; Konyali, Aynur; Semen, Zeynep
    This study aimed to investigate the genetic characterization and diversity of Hair goats from 10 regions using 20 microsatellite markers. A total of 522 alleles were observed. The INRA0023 locus exhibited the greatest number of alleles (48), while the DRBP1 locus had the highest effective allele number (16.27), and the BM1818 and DRBP1 loci had the highest polymorphic information content value (0.94). The expected heterozygosity value ranged from 0.85 (ILSTS011) to 0.94 (BM1818, SRCRSP15, and DRBP1). The Hair goat populations in Konya and Hatay displayed the lowest and highest allele numbers, with values of 10.40 and 16.25, respectively. The fixation index (FIS) values are significant in defining population structures and determining the extent of heterozygosity losses. The FIS values exhibited a range of 0.031 in Mu.gla to 0.226 in Burdur. A total of 107 unique alleles were identified in Hair goat populations. However, it is noteworthy that, out of all the alleles, only 25 had a frequency exceeding 5 %. The results indicate that the microsatellite markers utilized demonstrate sufficient levels of polymorphism, making them appropriate for efficiently investigating the genetic variability of Hair goat populations.

    Goat production systems of Turkey: Nomadic to industrial
    (Elsevier Science Bv, 2018) Daskiran, Irfan; Savaş, Türker; Koyuncu, Mehmet; Koluman, Nazan; Keskin, Mahmut; Esenbuga, Nurinisa; Konyali, Aynur
    Goats play an important socio-economic role in many marginal rural areas of the world. Indigenous goat breeds have taken an important role in the livelihood strategies of impoverished farmers, especially those in harsh, remote areas. Those roles include their use as security and diversification of assets, social and cultural functions. They are also valued for their productive performance, adaptation and disease resistance. Turkey is one of the leading countries in the world for goat population and production. Hair, Kilis, Angora and Shami are the main goat breeds of the country. Hair goats are raised in many parts of the country but are concentrated particularly in the mountainous regions country, while the Angora breed is concentrated mainly in Central Anatolia. Kilis and Shami goats are known for their higher milk yield and litter size and are mainly focused in the south-east region of Turkey. Apart from these four breeds, the minor breeds such as Honamli are located in the Bolkar Mountains in the Mediterranean region (specifically Antalya, Isparta and Konya) and the Norduz breed in Van province. A limited number of dairy goats such as Mainz, Saanen and their crossbreds are located in the Aegean and Marmara regions of Turkey. The population of goats in Turkey is about 11 million head. Hair goats make up approximately 10 million of the total number and the rest make up the balance. There are many reasons for goat production in Turkey, including the country's geography and ecological condition, as well as the socio-economic situation of the rural communities. Goats have been raised in the Anatolian Plateau for many centuries providing dairy, meat, hide and hair to the inhabitants. It is the main source of animal protein for the rural masses in the mountainous regions of the country and less so for the urban population. Goats provide approximately 3% of the total red meat, 2.5% of the total milk and 18.5% of the total hide production for Turkey. They are also the only source of mohair and animal hair production in the country. Although their number and economic significance has decreased over the years, goat breeding still plays and important socio-economic role for the people living in remote areas of Turkey. Investments in intensive goat enterprises have increased significantly in the last few decades in Turkey although marketing margins across the value chain between producers, middlemen, processors, and consumers unjustifiably irregular.

    Observations on hand-mating behaviors, several physiological and hematological parameters in Turkish dairy goats
    (Wiley, 2011) Konyali, Aynur; Tölü, Cemil; Ayag, Bekir Sitki; Akbag, Hande Isil
    The aims of this study were to examine hand-mating behavior of doe and buck and relationships of courtship behavior and physiological and hematological traits according to gestation results. Duration from beginning of observation until mating (M-C), duration between two copulations (C-C) and courtship behavioral index value of each sex (CBIVD; courtship behavioral index value of doe, CBIVB; courtship behavioral index value of buck) and mounting behavior of buck, were observed. Experience of doe was affected of CBIVD and CBIVB (P = 0.01 and P = 0.01, respectively). Bucks mounted significantly higher times on experienced does than on inexperienced ones (P = 0.00). On the other hand service number decreased with an increase in M-C (P = 0.00). Elevated service number was observed with increased mounting frequency of buck (P = 0.03). There were strong correlations between CBIVD and CBIVB (r = 0.48, P = 0.00). Pregnancy was not influenced by vaginal pH value. Does, which gave multiple births, had higher vaginal pH (P = 0.05). Rectal temperature difference of doe had no influence on success of mating and birth type. On the other hand, birth type was affected by rectal temperature difference of buck. There was no significant difference of hematological parameters according to mating results. Hemoglobin, red blood cell count and mean corpuscular hemoglobin concentration values were higher in single births and mean cell volume value was lower in single births.
