    Effect of pasture and feeding systems on hematological traits of ewes and lambs
    (Peerj Inc, 2025) Tolu, Cemil; Oral, Hulya Hanoglu; Alaturk, Firat; Gokkus, Ahmet
    Context Sustainable livestock production depends on efficient pasture management and the continuous monitoring of the health of grazing animals. Objectives This study investigated the effects of pasture types and sheep production systems on the hematological traits of Karacabey Merino (German Mutton Merino x K & imath;v & imath;rc & imath;k) ewes and lambs grazing on different pasture types throughout the year and reared in a semi-intensive system (control group). Methods In this twenty-six-month study, the hematological characteristics of ewes and lambs grazing on natural pastures and in spring (triticale and oat grass pasture), summer (sorghum Sudangrass and wheat stubble pasture), and autumn (triticale and oat grass pasture) were compared with ewes and lambs reared in a semi-intensive system (no pasture for lambs). A total of 36 ewes (aged 3-4 and 65.2 +/- 0.55 kg) and 98 lambs were used. There were 12 ewes in total in each treatment group and four ewes in subgroups. Each subgroup in the pasture was separated by fences. The 12 ewes tagged in the control group were within the unit sheep flock. Blood samples were taken from the jugular vein of ewes and lambs at three to four-week intervals during live weight weighing using 3-4 mL edged tubes and transported in the cold chain to the laboratory for analysis. Results Pregnant ewes grazing on natural autumn pasture had significantly lower red blood cell (RBC), hemoglobin (HGB), and platelet (PLT) counts (P < 0.05). Animals grazing on wheat stubble pasture exhibited higher hematological values compared to those grazing on Sorghum-Sudangrass pasture (P < 0.05). Lambs in the control group had lower hemoglobin (HGB) and hematocrit (HCT) levels during the post-weaning period than those in the pasture group (P < 0.05). Conclusions The hematological parameters of pregnant Karacabey Merino ewes grazing on natural pastures during the autumn season, as well as those of lambs raised in a semi-intensive system during the post-weaning period, should be carefully monitored. Additionally, appropriate feed supplementation, along with vitamin and mineral support, should be provided to maintain animal health and physiological balance.

    EFFECTS OF DIFFERENT DOSES AND TYPES OF FERTILIZERS ON GRAZING TIME AND RANGELAND QUALITY
    (Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Alaturk, Firat; Gokkus, Ahmet
    Experimental trails have been conducted between March 2010 and January 2012 in Gerlengec village of Biga District situated in Canakkale Province, Turkey. In this study, control along with 5 kg N/ha 4M (chelate organo-mineral fertilizer, 5-10-0), 10 kg N/ha 4M, 5 kg N/ha composite (20-20-0) and 10 kg N/ha composite of five different types and doses of fertilizer were used. Height of the grass has been increased from 10.0 cm to 110.9 cm and 22.8 cm to 113.1 cm in 2010 and 2011, respectively by increasing the grass layer of the rangeland from 1st March to 30th May. At the same time, the fodder production has been increased from 84.0 kg/ha to 494 kg/ha and 95.8 kg/ha to 631.1 kg/ha in 2010 and 2011, respectively. An increase, both in the grass layer height as well as the fodder production has been accelerated between 10 to 20 April. The application of fertilizers has none significant level of affect to the grazing maturity time of rangeland. The effects of fertilization on legumes in rangeland were important in general while its impact on the species of grains and other related families has mostly been appeared in the months of summer and autumn. According to the two-year average results, legumes that found in plant vegetation were increased by the application of composite fertilizer while decreased due to 4M fertilizer. All of the fertilizers showed an increase in gramineae but reduced the species from other families. All types and doses of fertilizer showed an increase into the quality level of rangeland in each of two years, but an extreme increase of 10 kg N/ha has been occurred in those plots which were applied to 4M fertilizer. According to this, grazing should be started in 20th of April in similar rangelands and 5 kg of nitrogen should be applied to per hectare for improving the quality of rangeland.

    Effects of Different Irrigation Levels on Growth of Hungarian Vetch (Vicia pannonica Crantz.) and Field Pea (Pisum arvense L.)
    (Kastamonu Univ, Orman Fak, 2016) Ozel, Sema Deniz; Gokkus, Ahmet; Alaturk, Firat
    The present study was conducted to investigate the effects of different irrigation levels (100, 75, 50 and 25% of field capacity) on above and underground organic biomass production of commonly grown Hungarian vetch (Vicia pannonica Crantz) and field pea (Pisum arvense L.). Experiments were carried out in laboratories in Field Crops Department of Canakkale Onsekiz Mart University between the dates 15.11.2014 and 15.05.2015. Experiments were conducted in randomized plots design with 4 replications. Current findings revealed that irrigation water levels significantly affected plant height, aboveground fresh and dry biomass, aboveground dry matter ratio and underground biomass of Hungarian vetch an Field Pea. The greatest plant height, aboveground fresh and dry biomass, dry matter ratio and underground biomass of both forage plants were obtained from 75% irrigation level. The plants produced the least organic matter at the lowest irrigation level. It was concluded that irrigations in Hungarian vetch and field pea should be initiated when the available soil moisture level dropped to 75% of field capacity.

    Effects of Prickly Burnet (Sarcopoterium spinosum (L.) Spach.) Control and Sheep Grazing on Hay Yield and Quality on Gokceada Island, Turkey
    (Mdpi, 2022) Alaturk, Firat; Gokkus, Ahmet; Parlak, Altingul Ozaslan; Baytekin, Harun; Tölü, Cemil
    Simple Summary This study was carried out to control the plant Sarcopoterium spinosum in canakkale, Turkey. As a result of grazing, the number of grasses and legumes decreased and the number of shrubs increased. The number of species increased due to shrub control measures but decreased remarkably with grazing. (1) Background: The effects of prickly burnet (Sarcopoterium spinosum) control measures (pulling out, burning and cutting) and grazing on the botanical composition, grazeable dry matter (GDM) yield and nutritional values of rangeland were investigated on Imbros Island (Turkey) in 2010-2013. (2) Methods: The rangeland was grazed by Imbros sheep during the last year of the experiment. About 0.15 ha of rangeland was allocated to each sheep and five sheep were placed in each plot. Grazing was continuous throughout the year. (3) Results: Shrub levels decreased by 50-60% due to pulling out, burning and cutting in the first year and herbaceous species increased. Forbs increased more in the pulled and burnt plots and grasses increased more in the cut plots. In the third year, the shrub level increased to 60-65% and herbaceous species decreased. The decrease in herbaceous species was observed mostly in forbs. Plant cover was mostly (58%) composed of annual species. Development decreased plant cover ratios, but this decrease ceased in the burnt plot in the third year. Grazing also reduced plant cover. Crude protein (CP), NDF, ADF and digestible dry matter (DDM) content did not vary significantly over the experimental period. CP and DDM increased, NDF decreased and ADF did not change in the development plots. Overall, significant differences were not observed in GDM yield and nutritional values due to development efforts (pulling out, burning and cutting). (4) Conclusions: However, cutting is difficult over stony and rough terrain and pulling out creates erosion on sloping surfaces. Therefore, burning is recommended over the entire rangeland and burning or pulling out is recommended over smooth terrain for the temporary control of S. spinosum.

    HERBAGE YIELD AND QUALITY OF WHEAT STUBBLE AND SORGHUM SUDAN-GRASS PASTURES
    (Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Parlak, Altingul Ozaslan; Gokkus, Ahmet; Alaturk, Firat; Hanoglu, Hulya; Tölü, Cemil
    Summers are hot and dry and winters are cool and precipitated in regions with dominant Mediterranean climate. Since the pastures totally dry out during hot-dry period, sheep usually graze over wheat stubble in Turkey. The present study was conducted to investigate the herbage yield and quality of wheat stubble and Sorghum Sudan-grass pastures during summer dry periods and to compare live weight gains of the sheep grazed over these pastures. In sorghum Sudan-grass pastures, sheep (4 Karacabey merino race sheep x 3 replications) freely grazed in each plot for two-and-a half month (July-August-September) when the plants had 50-75 cm heights. Similar grazing treatments were also performed over wheat stubble. Dry herbage yields of wheat stubble and sorghum sudan-grass pastures were respectively observed as 2.82 ton/ha and 10.0 ton/ha. Considering the herbage quality of the wheat stubble, crude protein was 6.28 %; NDF was 66.54%. ADF was 37.88%, ADL was 4.37%, DMD was 60.25%, ME was 2.18 Kcal/kgKM. The same values were respectively observed as 11.33%, 61.13%, 31.58%, 2.99%, 67.27%, 2.43% in sorghum sudan-grass pasture. Traditional sheep grazing can be performed over wheat stubble pastures, but supplementary energy feed with CP should be provided. Sorghum sudan-grass can also be cultivated as an alternative to traditional stubble grazing. In this case, there is no need for supplementary feeds.

    (Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Tölü, Cemil; Alaturk, Firat; Gokkus, Ahmet; Savaş, Türker
    In this study, seasonal changes in daily behavioral rhythms of Gokeada sheep into the pastures were investigated. The research was conducted at Gokeada Island located at the far-west end of Turkey in Aegean Sea. This study is a part of 3-year rangeland reclamation project. Experiments were conducted into 8 plots surrounded with fences including 3-4 years old 40 head sheep (0.15 ha/sheep) grazed into the rangeland for a year. Prickly burnet cover ratio was found between 71.4-88.2% in reclaimed plots 95.7-94.9% in control plots. The sheep were observed through directs observations with sampling method in day-time. Significant differences were observed in grazing behaviors of Gokeada sheep in different seasons (P< 0.0001). Grazing frequency was high in winter and spring seasons and low in summer season (P= 0.05). The sheep grazed in winter and spring seasons 2 times higher than autumn season. Grazing frequency was quite low in summer season. The sheep grazed in summer season rather in cool hours of the morning and evening. They spent rest of the day with resting and rumination. They spent majority of the day with grazing in winter and spring seasons. It has been concluded in this study that Gkeada sheep, raised almost under wild conditions, were able to self-sustain into the rangeland with dominant prickle burnet cover through efficiently benefiting from prickly burnet in all season.

    The Effect of Auxin and Auxin-Producing Bacteria on the Growth, Essential Oil Yield, and Composition in Medicinal and Aromatic Plants
    (Springer, 2020) Cakmakci, Ramazan; Mosber, Goltay; Milton, Ada Hazal; Alaturk, Firat; Ali, Baboo
    Aromatic plants had been used since ancient times for their preservative and medicinal properties, and to impart aroma and flavor to food. Also their secondary metabolites are economically important as drugs, flavor and fragrances, pharmaceuticals, agrochemicals, dye, and pigments, pesticides, cosmetics, food additives, other industrially biochemical, and also play a major role in the adaptation of plants to their environment. Indole acetic acid-producing rhizobacteria inoculations increase in stomatal density and level of secondary metabolite and have a synergistic effect on monoterpene biosynthesis. Bacterial inoculation significantly affected and increased the chemical composition of essential oil, citronellol, and geraniol content in rose-scented geranium; essential oil composition and total phenolic content in marigold; density, number, and size of glandular trichomes in sweet wormwood and peppermint essential oil components such as geranyl acetate, limonene, and beta-pinene in coriander; oil yield and content in calendula; yield of the herb in hyssop; oxygenated compounds, essential oil content and yield, anethol and changing the chemical composition in fennel; growth, number of glandular trichomes and essential oil yield, root branching and length, and total amount of essential oil, production of monoterpenes such as pulegone, menthol, menthone, menthofuran, and terpineol content, biosynthesis of secondary metabolites in peppermint; growth and essential oil yield in marjoram; glandular hair abundance, essential oil yield, and monoterpene biosynthesis in basil; phellandrene, limonene, borneol, and campor in rosemary; carvacrol, thymol, linalool, and borneol in oregano; and alpha-thujene, alpha-pinene, alpha-terpinene, p-simen, beta-pinene, and gamma-terpinene contents and essential oil yield in summer savory. Inoculation with IAA-producing bacteria medicinal roots increased the valerenic acid in valerian, essential oil and quality in vetiver, curcumin content in turmeric alkaloid and ginsenoside content in ginseng, and inulin content in Jerusalem artichoke.

    (Kastamonu Univ, Orman Fak, 2016) Cebeci, Gurkan; Gokkus, Ahmet; Alaturk, Firat
    In this study, were determined the effects of row spacing on some agricultural properties of the guar (Cyamopsis tetragonobla). The experiment trials for this study were conducted in the Canakkale Onsekiz Mart University at Dardanos Research and Experimental Trials Unit of the Faculty of Agriculture in 2015. The experiment using Randomized Complete Block Design with 3 replications was applied two Guar. Five row spacing (20, 40, 60, 80 and 100 cm) according to the results. Row spacing had no effect to plant height and dry matter contents as it significantly affected alter properties. The highest green (2323.70 kg da(-1)) and dry (714.1 kg da(-1)) hay yield were obtained from 20 cm row spacing. Maximum number of branches (8.73 number) and flowers (72.40 number) were obtained from the row spacing of 100 cm while the number of leaves (247.23 number) and of stem diameter (11.59 mm) were achieved using 80 cm of row spacing. The number of branches, number of leaves and stem diameter increased with wider row spacing due to the availability at were space per plant to grow, but green and dry hay yields were decreased. In conclusion, 20-40 cm at row spacing may be suggested in guar for hay production.

    (Elsevier Science Bv, 2016) Gokkus, Ahmet; Kahrıman, Fatih; Alaturk, Firat; Ali, Baboo
    This study was aimed to determine the variations into the nutrient contents found different plant parts of maize genotypes that containing high level of oil and protein at their different vegetative stages. In this study, six different maize genotypes were used as plant materials that have been generated by crossing of two special types of maize namely, IHO and IHP with two normal elite inbred lines (B73 and Mo17). Field trials have been conducted by using randomized complete block design along with three replications in the region of northwest of Turkey. Samplings were designed in accordance to plant sowing date and they were taken from the field at 40th, 60th, 82nd, 100th and 122nd days after sowing. Neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), crude ash (CA), organic matter digestibility (OMD) and dry matter digestibility (DMD) have been investigated during this study work. The results of this research showed that the significant differences were found among genotypes and some sorts of significant variations have been observed into the cell wall components. Genotypes, having high level of protein in their stalks, have been found superior in terms of nutrient content while the genotypes, having high level of oil in their leaves, were found best for nutrient values.
