This study was conducted using a Cross-Sectional Observational Design to determine the effects of current managerial practices applied in commercial dairy cattle farms in Çorum Province on calf survival. The main material of the study consisted of 120 active farms, which represent the general structure of the dairy cattle sector in the region. Data were collected via face-to-face surveys, and the scale’s reliability was confirmed (Cronbach’s Alpha: 0.742) and suitability for Factor Analysis (KMO: 0.710) was verified. The results showed that while 88.33% of the farmers were members of a cooperative/union and 57.50% reported timely colostrum administration (within the critical <4 hours), these positive indicators contrasted sharply with low biosecurity and poor practical application. Specifically, calf mortality was high (42.50% of farms reported mortality rates >5%), mainly due to diarrhea and pneumonia, with 65.83% of deaths occurring in the first 30 days. Critical management deficiencies included uncontrolled colostrum feeding (85.00% via suckling, risking failure of passive transfer), severe biosecurity breaches (85.83% of calves housed with adult animals), and delayed introduction of solid feed. In conclusion, the primary challenge in Çorum is not lack of institutional access or basic knowledge, but rather a critical disconnection between theoretical knowledge and practical management implementation. To improve calf survival, management strategies should shift from traditional suckling to controlled colostrum protocols and emphasize the transition from group housing to individual calf hutches to ensure biosecurity.

Progranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0-90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100-150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process.

-In this study, we aimed to determine the effect of Moringa oleifera essential oil (MOEO) supplementation to rations of Japanese quail (Coturnix coturnix japonica) grown under heat stress (HS) on some adipokine (visfatin, adiponectin, and chemerin), intestinal (citrulline), 3,5,3 '-triiodothyronine (T3), thyroxine (T4), and thyroid-stimulation hormone (TSH) levels in the serum. For this purpose, 320 day-old male quail chicks were used. The study was conducted over 42 days, including a 7-d adaptation period and a 35-d experimental period. Eight trial groups were established, each including 10 quail: CT (control temperature, 25 celcius), MOEO 200, MOEO 400, MOEO 600, HSC (HS control), SMOEO 200, SMOEO 400, and SMOEO 600. Based on the results, a dose-dependent decrease was observed on days 21 and 42 in serum adiponectin and T3 in the stress and stress-free groups compared with the control group due to MOEO supplementation. The lowest decrease was observed in the MOEO 600 mg/kg dose group. In addition, an increase in stressed groups was observed when examining serum citrulline levels, while chemerin levels did not have a statistically significant effect. While the decrease in serum visfatin, T4, and TSH levels on the 21st day did not have a statistically significant effect, a significant effect was determined on the 42nd day. The addition of MOEO at 600 mg/kg to the ration may be beneficial in preventing intestinal damage and inflammation that may occur due to HS.

This study investigated the effects of dietary probiotics (Lactobacillus reuteri E81 [LRE], Lactobacillus rhamnosus GG [LRG]), yeast (Saccharomyces cerevisiae S81 [SCS]), and their combined supplementation on fattening performance (BW, DWG, FI, and FCR), meat quality, and rumen and duodenum histology in lambs. The study material comprised ninety 2.5-month-old Anatolian Merino lambs, and the trial was conducted for 70 days. Nine trial groups, each composed of 10 animals, were established. This study demonstrated that, when compared to the control group, the best fattening performance was achieved in the lambs that received 600 ppm of dietary LRE. Neither visceral organ weights nor rumen and duodenum histology was affected in the groups that received the tested feed supplements. Of the meat colour parameters investigated, the L* value was observed to have increased in the groups that were given feed supplements, excluding Groups LRE-600 and SCS-300. It was determined that the probiotic supplements had no effect on the a* and b* colour parameters, but affected the meat pH value. In conclusion, the assessment of the effects of different doses of dietary probiotics, yeast, and probiotic-yeast combinations on performance parameters, visceral organ weights, and meat quality in Anatolian Merino lambs showed that the best results were achieved in the group that received 600 ppm of LRE alone.

Dünyada olduğu gibi Türkiye’de de gelişen bilim, teknoloji ve sanayi ile buna bağlı olarak değişen kırsal kalkınma ve üretim anlayışı, tarımsal faaliyetlerin gerçekleşme şeklini değiştirmiştir. Yeni üretim metotları sonucu çevre ve insan sağlığı bozulmuş ve gelinen noktada bilim insanları organik tarıma yönelmiştir. Ülkemizde 1980’li yıllarda başlayan organik tarım uygulamaları, 1994 yılında organik tarım yönetmeliğinin yayınlanmasıyla önemli ölçüde gelişme göstermiş ve yönetmelik son olarak 2018 yılında düzenlenmiştir. Ülkemiz toprak ve su kaynakları, iklimi, ürün çeşitliliği bakımından organik tarıma elverişli koşullara sahip olması dolayısıyla organik tarımın yıllar içerisinde nasıl bir ilerleme gösterdiğini ve bugün ne aşamada olduğunu görebilmek amacıyla bu çalışma hazırlanmıştır. Türkiye’ de 1990 yılında 1.037 ha alanda 313 çiftçi ile 8 organik ürün üretilmiştir. Son verilere göre 73.563 çiftçi 626.885 ha organik tarım alanında 2.371.612 ton organik ürün yetiştirmiştir. Ayrıca üretimi yapılan organik ürün çeşidi de 213’e çıkarılmıştır. İhracat durumuna bakıldığında toplam ihracat miktarının 111.690.675 ton olduğu ve bu ihracat miktarının önemli bir miktarını 41.633.896 tonla buğday ve buğday ürünlerinin oluşturduğu görülmektedir. İthalat verilerine bakıldığında ise toplam ithalat miktarının 175.865,85 ton olduğu ve en çok ithal edilen ürünün ise soya fasulyesi (tohumluk olmayan) (99.446 ton) olduğu bilinmektedir. Geçmiş yıllara göre organik tarım üretiminde önemli bir artış gözlense de Türkiye’nin tarım potansiyeli göz önünde bulundurulduğunda bu artışın daha da artabileceği öngörülmektedir.

Apelin is an important adipokine hormone that is released from adipose tissue, which is considered as the energy store of the body, which plays a role in many physiological processes in the body, as well as cardiovascular, immune functions and energy, nutrients and fluid metabolism. In this study, it was aimed to determine the effect of lactation, pregnancy and gender on apelin hormone levels in blood serums belonging to different races of ewe. In the present study, the hormone levels of the pregnant, non-pregnant ewe and rams of the Akkaraman Kangal and Morkaraman races were thin, with different body condition scores (<2, 3 to 3.5 and ≥4). Apelin hormone level was determined by ELISA technique in blood serum samples of ewe's Jugular vein. It was determined that there was a difference in body scores between races and the interaction between race and body score was important (P<0.05). Apelin level in ewe in lactation and pregnant ewe did not change according to body condition scores (P>0.05). In terms of apelin, gender and body condition score, race and gender, and body condition score interactions were found to be significant.

The present study was aimed at investigating the effects of the dietary use of different doses of Moringa oleifera essential oil (MOEO) on performance parameters, internal organ weights and meat quality in Japanese quails (Coturnix coturnix japonica) exposed to Heat Stress (HS). For this purpose, 320 male day-old quail chicks were used. Seven days of preliminary (physical exercise) and a 35-day fattening period were applied. The animals were divided into 8 groups, each including 40 animals according to temparature (C: 25 °C and SC: 37 °C) and dietary doses (C, 200, 400 and 600). Each group was divided into 4 subgroups, each comprising 10 animals. The consequences of this study showed that, in the stress-free (HSF) groups, while all of the different doses of dietary MOEO positively affected growth performance, feed intake and feed efficiency, in the HS groups, similar positive effects were observed with the use of 200 ppm of dietary MOEO. While no effect was detected on internal organ weights on Days 21 and 42 in the HSF and HS groups, a dose-dependent increase was determined in the intestinal pH value on day 42 in the HS group (p <.05). Additionally, in the analysis of meat quality on the 21st and 42 days compared to the controls, no effect was observed on the meat colour parameters value and TBARS level in the HS and HSF groups. Based on the consequences of this study, it is considered that, MOEO could be used as an alternative product in poultry, at a dose of 200 ppm, to reduce the detrimental effects of HS.HIGHLIGHTS Temperature stress, performance parameters and serious problems in the health of poultry. Moringa olifera helps regulate performance parameters in poultry exposed to heat stress. Since the addition of Moringa oleifera to the diets does not affect the organ weight and meat quality in 21 and 42 days, it does not cause any negative effects for the consumer.

The purpose of this study was to examine the effect of adding an essential fatty acid mixture (EOM; Eucalyptus globulus Labill, thymus vulgaris, Cymbopogon nardus, and Syzygium aromaticum) to the drinking water in the heat stress broilers on the adipokine (Apelin, BDNF) response, the histopathologic changes in liver and intestines, and some biochemical parameters. This study lasted for a total of 42days, including the physical exercise period (7days) and the fattening period (35days). A total of 400 Ross 308 male broilers (1-d-old) were randomly divided into 8 groups (50 animals per group), each of which was exposed to various conditions of temperature (C: 22°C and SC: 36°C) and treatment dose (C, 250, 500 and 750mL/1000 L). Each group was divided into 5 subgroups, each comprising 10 animals. In the stress-free groups, whereas the Apelin level linearly decreased, the BDNF level linearly increased. In histopathology, the liver tissue was found to be normal in all groups whereas the duodenum villi length was found to increase in the group of 750mL/1000 L. No statistically significant difference was found between the stressed groups and the non-stressed groups in terms of VLDL, Glucose, Total bilirubin, ALT, and TG (p >.05). While Apelin level increased in the stressed groups, the BDNF level increased in the group of 250mL/1000 L. In the histopathological examination, a small amount of coagulation necrosis was detected in hepatocyte, a diffuse hydropic degeneration was observed in hepatocytes, and finally a dilatation and hyperaemia were seen in sinusoid in the groups of EOM-500mL/1000 L and EOM-750 m/1000 L compared to the control group. Whereas there was no difference between the group of EOM-250mL/1000 L and the control group in terms of duodenum villa length, there was a significant decrease in other groups (p <.00). In conclusion, this study showed that adding 250mL/1000 L of EOM to the drinking water had a positive effect on the serum levels of Apelin and p-BDNF in the groups exposed to stress (p <.05).HIGHLIGHTS Heat stress results in serious annual economic losses in the poultry industry. Essential oil fatty mix acids have positive effects on poultry health. Apelin and BDNF may be a protective factor against deleterious consequences of chronic exposition to heat stress.

Organik olarak üretilen tavuk yumurtasının daha fazla besleyicilik ve duyusal özelliklere sahip olmasının yanı sıra sağlığa zararlı herhangi bir madde içermemesi, tüketicinin öncelikli beklentilerindendir. Araştırmalar, beklenenin aksine; kafes yumurtaları ile organik yumurtaların kuru madde, lipit ve yağ asitleri arasında önemli bir farklılık bulunmadığını göstermektedir. Organik yumurtanın kafes yumurtasına göre yaklaşık iki kat fiyata satılmasının sadece psikolojik ve etik motivasyon taşıdığı bildirilmektedir. Avrupa Birliği Konseyi organik yumurta üretiminde tavukların bazal rasyonun yanı sıra yeşil kaba yem materyallerine erişimini de gerekli görmektedir. Ancak bu erişimin sağlanması durumunda, organik olarak üretilen yumurta tüketici beklentilerine karşılık verebilir. Araştırmalar ülkemiz Organik Tarım Kanuna göre tavuk başına ayrılan 4 m2 'lik gezinti alanının bu talepleri karşılamada yeterli olmadığını göstermektedir. Bu durum tavuklara ayrılan gezinti alanının çeşitli yem bitkileri ile rotasyona uygun olarak ekili olmasını sağlayacak şekilde artırılmasını veya gezinti alanına dışarıdan ilave yeşil kaba yem materyallerinin getirilmesini zorunlu kılmaktadır. Böylece fonksiyonel gıda özelliği olan bir ürün elde etmenin yanı sıra gagalama ve kanibalizmin azalarak hayvan refahının arttığı bir üretim tarzına ulaşılmış olacaktır. Bu derlemede organik yumurta üretiminde başta karotenoidler olmak üzere yağ asitleri gibi kimyasal içeriklerin artırılması ile renk, koku ve tat gibi duyusal özelliklerin iyileştirilme olanaklarına yönelik uygulamalara yer verilmiştir.

Milk samples were collected from 9 conventional farms and 9 organic farms during one year time, at six different months (December 2013 to October 2014), and all farms were selected from the same geographical locations. All organically managed farms had organic production certificates given by the Republic of Turkey Ministry of Food, Agriculture and Livestock. The count of TAMB, coliform, and coagulase positive S. aureus were affected by production systems at the level of p<0.01; yeast and mold, and somatic cell count (SCC) were affected at the level of p<0.05. But, differences according to months were statistically significant only on TAMB (p<0.01) and coliform (p<0.05) counts. The general means of TAMB, coliform and yeast and mould counts of the organic milk (OM) were significantly lower (p<0.05), while the general means of SCC and coagulase positive S. aureus count of the OM was significantly higher (p<0.05) compared to conventional milk (CM). Antibiotic residue was determined in one of the CM sample and in two of the OM samples. Our study is the first research that compared conventional and organic milk in Turkey. This study indicated that the microbiological quality of OM was the higher in terms of TAMB, coliform and yeast and mould, whereas was the lower in relation to SCC and coagulase positive S. aureus counts. But, the quality of both milk types should be improved.

The majority of farm households in Turkey and especially the Eastern Anatoliaare still based on low-input semi subsistence agriculture and livestock production. Despite a slow decline in recent years, agriculture and livestock production remains a major employer in Turkey and it is a significant contributor to the country's gross domestic product, GDP. Whist Turkey is one of the EU candidate countries, is self sufficient in food production and Turkish agriculture is poorly structured inefficient, with farming in the Eastern Anatoliabeingmainlysubsistencefarming. Yet,thesetraditionalruralstructures combined with poor access to low level of education and low level of off-farm unemployment problem makes the situation more complicated and unsustainable. The best way to promote sustainability, better and higher production of Eastern Anatolian and rural Turkey is to invest in the local people, villages through improved, continuing and effective agricultural and livestock programs in particular.Investment in human capital especiallyintheruralareasleadstomoreemploymentopportunitiesthrough entrepreneurship and innovation in organic agriculture and livestock production. A holistic approach to developing and improving supply chains could unlock the potential forsophisticated,state-of-the-artorganicagricultureandlivestockproducersand businesses in the region to become EU and global players. Eastern Anatolian livestock producers and the farmers have the ambitions to take part in future progress because the region is naturally organic not by design but default.It is for sure that present potential of the region has not been fully determined and utilized. EU has greatly benefited from previous enlargements economically, politically and socially. When European Union (EU) and Turkish Government relations considered and accession of Turkey to EU would be the logical consequence of the previous accessions. The screening on chapter 11 (Agriculture and rural development) is one of the important criteria and Turkey is working on to meet these benchmarks.

Bu çalışmada, Siyah Alaca ineklerde güç ve ölü doğumun takip eden laktasyon performansına etkisinin belirlenmesi amaçlanmıştır. Bu amaçla, Gümüşhane ili Kelkit ilçesinde faaliyet gösteren özel bir sığırı işletmesinde 2005-2006 yılları arasında doğum yapan 326 Siyah Alaca ineğin 591 doğum ve süt verim kayıtları kullanılmıştır. Çalışmada, ölü doğum ve güç doğumla birlikte, buzağılama yılı ve mevsimi, doğum sırası ve doğum tipi gibi değişkenlerin 305 günlük süt verimi ve sağılan gün sayısına etkisi de araştırılmıştır. Siyah Alaca sığırlarda güç doğum ve ölü doğum ortalaması sırasıyla, %8.7 ve %9.1 olmuştur. Güç doğum yapan ineklerin 305 günlük süt verimi (608.6 kg) ve sağılan gün sayısı (23.1 gün) normal doğum yapanlara göre önemli oranda daha düşüktür (P<0.01). Ölü doğum gerçekleştiren ineklerin, sağ doğum gerçekleştirenlere göre 305 günlük süt verimi ve sağılan gün sayısı sırasıyla 925.7 kg ve 26.5 gün daha azdır (P<0.01). Sonuç olarak, süt ve buzağı kayıpları başta olmak üzere önemli ekonomik kayıplara neden olan güç ve ölü doğum, aynı zamanda hayvan refahı bakımından bazı sorunlar teşkil etmektedir. İyi bir sürü yönetimi ile bu etkiler azaltılabilir.
