(Wiley, 2024) Unay, Engin; Okuroglu, Alaeddin; Tirpan, Mehmet Borga; Coskun, Muhammed Ikbal; Sevgi, Ramazan; Yilmaz, Mehmet Ali; Unal, Ilker
This study aims to investigate the relationship between metabolic parameters and the number of embryos produced in superovulated cows with high genetic characteristics in milk yield. Eighteen Holstein donors were treated with classic superovulation protocols, AI and flushing. During superovulation, decreasing doses of FSH (follicle-stimulating hormone) were administered at 12-h intervals for 4 days. Plasma insulin-like growth factor (IGF1), glucose (GLU), beta-hydroxybutyric acid (BHB), non-esterified fatty acid (NEFA), blood urea nitrogen (BUN) and total protein (TP) levels were determined by using an autoanalyzer. The mixed model analysis of variance was used for statistical analysis. As a result, plasma IGF1, BHB and BUN had significant interactions with both groups and days (p < .05). Additionally, plasma TP-days interactions were significant (p < .05). Furthermore, there was a negative correlation between the number of embryos and plasma BHB levels (p < .05). In conclusion, under appropriate environmental conditions, metabolic profile control of donors can contribute to the embryo production process and to the studies on the metabolic infrastructure.
First dose optimization study on freezing Anatolian buffalo semen
(Ankara Univ, 2024) Bastan, Ilktan; Sahin, Derya; Korkmaz, Firat; Simsek, Seher; Kaya, Ufuk; Satılmış, Muharrem
The main objective of sperm production centers is to produce as many straws as possible from the obtained ejaculates using the optimal dilution rate. To this end, this study is the first to evaluate the effect of different semen extender rates on Anatolian buffalo semen quality. Ejaculates were collected by artificial vagina from three Anatolian buffalo bulls. These ejaculates were divided into three aliquots and filled into 0.25 ml straws with soy-based extenders at concentrations of 35, 25, and 15 million sperm/straw (n=105). The straw samples of different sperm concentrations were frozen. The quality of sperm was evaluated after thawing (37 degrees C, 30 sec) and following the thermoresistance test (37 degrees C, 3 h). The post-thaw total motility and progressive motility values were similar between the groups. However, following the thermoresistance test, there was a significant decrease in total motility in the 35 million sperm/straw group, and the progressive motility was significantly higher in the 25 million sperm/straw group. There was no statistically significant difference between the groups in terms of sperm kinetic parameters, except for VSL after thawing, as well as VAP and LIN values following the thermoresistance test. The overall mean PMAI and STR values were the highest in the 25 million sperm/straw group. In conclusion, it is recommended to dilute the Anatolian buffalo semen at a concentration of 25 million/0.25 ml when freezing it with a soy-based semen extender. In addition, it is considered that soy-based extenders compensate for cryo-damage to sperm motility for a short time, and the thermoresistance test should be applied for objective evaluation in dose optimization studies.
Evaluation of colostrum quality and passive transfer immunity in terms of heat stress and disease incidence in Holstein cattle in Central Anatolia
(Ankara Univ, 2024) Kara, Halime; Güven, Mustafa
The effects of heat stress on colostrum quality, passive transfer failure, and disease incidence were investigated in a large population in order to prevent calf morality and yield losses in Holstein cows and calves. There was a statistically significant correlation between colostrum quality and the daily temperature humidity index, 7-day average temperature stress, and average temperature humidity indexes experienced by the cows during the dry period (P<0.001). It was observed that passive transfer failure occurred in 21% of the calves. There was a significant positive correlation (P<0.05) between the relative humidity and the temperature and humidity index values of the day of birth and the calf serum brix value. A negative and significant correlation was observed between Temperature-Humidity Index (THI) and serum brix value (r =-10, P<0.01). It was observed that the passive transfer success and diarrhea and pneumonia that were overcome in the first 365-day period showed a negative correlation (P<0.01). As a result, it has been observed that the heat stress experienced by cows and calves affects colostrum quality and passive transfer success, which also affects development and protection from diseases.

(2021) Yıldırır, Zulal Tavlı; Kızıl, Sedat Hamdi; Okuroğlu, Alaeddin; Satılmış, Muharrem; Karaşahin, Tahir; Yılmaz, Mehmet Ali; Ertem, Talha Burak
This study aimed to evaluate the superovulation response in Eastern Anatolian Red (EAR) cows treated with a single epidural injection or traditional administration of follicle stimulating hormone (FSH). Eight cows were randomly divided into two groups, as control (CG) and experiment (EG). Four replications were applied for each animal in the groups. A total of 16 studies were carried out in each group. In this study,300 mg intramuscular (i.m) FSH injection was applied with decreasing doses twice daily for four days to the cows in the CG. (70:70, 50:50, 20:20, 10:10 mg). On the other hand, 300 mg FSH was administered as 150 mg epidural and 150 mg intramuscular injection to the cows in EG. The number of untransferable embryos and the total CLs were found statistically significant (p<0.05). However, the number of transferable embryos and unfertilized oocyte (UFO)were found statistically insignificant among the groups (p>0.05). According to the obtained data, it was observed that the epidural administration of FSH for superovulation in EAR cows did not provide sufficient follicle and oocyte development. In conclusion, different studies with different superovulation protocols and FSH doses in local breed EAR cows will be needed for further studies.

(2021) Baştan, İlktan; Şahin, Derya; Korkmaz, Fırat; Şimsek, Seher; Satılmış, Muharrem
Conventional buffalo semen freezing studies are limited in Anatolian buffaloes, which are overly sensitive to exogenous stimulation. The present study's object was to determine the main features of Anatolian buffalo semen obtained by artificial vagina method for the first time. A total number of 150 ejaculates were collected from three Anatolian Buffalo bulls (app. 4 years of age). The mean pH, volume and concentration of semen were found 6.63±0.15, 1.61±0.5 ml, 1629±222.67 x106 spermatozoa/ml, respectively. The sperm motion characteristics were determined by using a computer-assisted sperm analysis system (CASA); the total and progressively motile sperm values were 57.12±5.63%, 23.22±4.47% and other kinetic parameters such VAP, VSL, VCL, ALH, BCF, STR, LIN were found 94.71±8.48 µm/s, 72.6±7.08 µm/s, 160.9±15.66 µm/s, 7.8±3.75 µm, 29.15±1.56 Hz, 76.91±3.87%, 46.21±2.61%, respectively after thawing. Among buffalo bulls, differences in semen pH values were statistically significant (P>0.05), while differences in ejaculate volume, semen concentration, total motility, progressive motility, VAP, VSL, VCL, ALH, BCF, STR, and LIN were not (P>0.05). As a result, frozen Anatolian buffalo semen can be obtained economically and can be used for animal breeding in assisted reproductive biotechnology such as artificial insemination or in vitro embryo production commercially.

Yield components and Crop Water Stress Index (CWSI) of mung bean grown under deficit irrigations
(Springer, 2022) Gölgül, İhsan; Kırnak, Halil; İrik, Hasan Ali
This study was conducted in 2018 growing season to determine the response of mung bean to water stress. Effects of different irrigation levels on mung bean yield and yield components and potential use of crop water stress index (CWSI) in mung bean irrigation scheduling were also investigated. Five different irrigation levels (I-100, I-75, I-50, I-25 and I-0) were applied through drip irrigation system. Amount of irrigation water supplied varied between 20-445 mm. Plant water consumption (ET) values varied between 125-521 mm. The highest yield (163 kg/da) was obtained from full-irrigation (I-100) and the lowest yield (39.7 kg/da) was obtained from rain-fed (I-0) treatment without irrigations. Plant heights varied between 58.6-21.2 cm, the first pod heights between 17.4-29.3 cm, number of branches per plant between 1.00-2.77 and number of pods per plant between 3.2-18.9. Water use efficiency (WUE) values varied between 0.31-0.50 kg/m(3) and irrigation water usage efficiency (IWUE) values varied between 0.37-0.77 kg/m(3). Crop water stress index (CWSI) values varied between 0.13-0.93. The lower limit (LL) equation was obtained as Tc-Ta = -2.9674 x VPD + 4.1341 (R-2 = 0.66) and the upper limit (UL) was identified as 9.7 degrees C. Highly significant (p < 0.01) correlations were seen between CWSI and yield. Based on present findings, I-75 was recommended under water deficit conditions. CWSI values of between 0.13-0.22 can be used to initiate irrigations for drip-irrigated mung bean.

(Taylor & Francis Inc, 2021) Behrem, Sedat; Keskin, Mahmut; Gül, Sabri; Unay, Engin; Satılmış, Muharrem; Ünal, Murat; Erisek, Abdülkadir
This study aimed to investigate the coarse outer guard hair and the fine down hair (cashmere) characteristics of Kilis and Damascus goats and to evaluate their potential for industrial use. Yearling goats, goats at first birth, second birth, and third birth were used as animal materials from Gaziantep. From the shoulder, rump, and rib areas of each goat, 20-25 g of the guard hair and the fine down hair (cashmere) samples were collected. These samples were examined in terms of diameter, length, tenacity, and elasticity at the Fleece and Mohair Laboratory of the International Livestock Research and Training Center. In the study, the average fiber diameter values were determined as 15.0 +/- 0.08 and 15.1 +/- 0.07 microns, and the fiber length values were 23.4 +/- 0.38 and 22.4 +/- 0.34 mm for Kilis and Damascus goats, respectively. In the light of these results, it can be said that the cashmere fiber diameter for both breeds is suitable for the textile industry. On the other hand, the fiber length is not long enough for the textile industry but can be evaluated by hand weaving method.
