Publication Comparison of milk yield and animal health in turkish farms with differing stall types and resting surfaces(Asian-Australasian Assoc Animal Production, 2015-02-01) Kara, Nurcan Karslıoğlu; Galiç, Aşkın; Koyuncu, Mehmet; KARSLIOĞLU KARA, NURCAN; KOYUNCU, MEHMET; Ziraat Fakültesi; Zootekni Bölümü; 0000-0003-0379-7492; AAG-8536-2021; ABB-3323-2020The current study was carried out to determine the influence of different resting surfaces and stall types on milk yield and animal health. Study was carried out in Bursa that is one of the most important cities of Turkey in terms of dairy production. Effects of resting surfaces and stall types on milk yield were found to be important. Also influence of different resting surfaces and stall types on lactation length was examined and found that rubber mats were different from the two other options. Relationships between different resting surfaces or stall types and health problems were examined and connection between stall type and repeat breeding (RB), dystocia, retained placenta and a connection between resting surface types and RB and clinical mastitis were found to be important. Considering their economic reflections, it can be said that results are quite important to the Turkish dairy industry.Publication Relationship of age at first calving, first lactation milk yield, reproductive performance and diseases in simmental dairy cows in Turkey(Zoological Soc Pakistan, 2023-02-01) Kara, Nurcan Karslıoğlu; KARSLIOĞLU KARA, NURCAN; Ziraat Fakültesi; Zootekni Bölümü; ABB-3323-2020The aim of this research was to determine the relationship between age at first calving (AFC) and first lactation milk yield [adjusted 305-day (MY305)], reproductive performance [days open (DO), calving interval (CI)] and diseases (lameness, mastitis, metritis and dystocia) in Simmental dairy cows bred under Turkey conditions. A total of 1110 Simmental cows (first calving to second calving) were assessed according to study criteria. While the relation between AFC and disease incidence and MY305 was not found significant, the relation between AFC and CI and DO was found significant and the optimum interval of AFC was determined 684 <=(I) over dotBY < 30 d for minimum CI and DO. Even though relation between AFC and diseases was not significant, it can be said that the same interval is advantageous for low disease incidence in Simmental cows. Furthermore, it can be accepted that the same interval is optimum also for the best lactation milk yield since it was not found a significant relationship among the average milk yields according to AFC. In conclusion, it can be said that planning the reproductive management practices according to these results will be beneficial for the optimal balance between economic benefit, animal health and milk yield.Publication Evaluation of pasture-based vs. concentrate-based lamb production systems regarding growth performance, wool cortisol concentration, meat quality and microbiological properties(Elsevier, 2023-07-05) Yılmaz, Onur; Demirel, Gülcan; Tüzün, Ahmet Engin; Kara, Nurcan Karşlıoğlu; Ekiz, Bülent; KARSLIOĞLU KARA, NURCAN; Ziraat Fakültesi; Zootekni Bölümü; ABB-3323-2020The aim was to investigate the growth rate, log transformed wool cortisol concentration (WCC), carcass char-acteristics, meat quality and meat microbiological properties of Akkaraman, Karya and Kivircik lambs in pasture -based (n = 93) and concentrate-based (n = 85) systems. Production system had no influence on the lamb growth rate in Akkaraman and Kivircik lambs. Weights of Karya lambs on days 90 and 120 were lower in pasture lambs than concentrate fed lambs. In some sampling days, log WCC was higher in lambs fed concentrates. Lambs of pasture-based and concentrate-based systems had similar carcass weight, dressing percentage, meat pH and shear force values in all breeds. However, meat of pasture-based system was darker with a lower L* value. Production system had no significant influence on bacterial counts, except Pseudomonas spp. counts in Akkaraman lambs. In conclusion, pasture-based system had no disadvantage in lamb finishing compared to the concentrate-based system regarding carcass characteristics and meat quality, except meat colour.Publication Effects of herd size and bedding surfaces on milk yield and some health problems in dairy cow farms(Sivar-soc Italiana Veterinari Animali Reddito, 2022-02-01) Galiç, Aşkın; Kara, Nurcan Karslıoğlu; KARSLIOĞLU KARA, NURCAN; Veteriner Fakültesi; ABB-3323-2020Dairy farms around the world have undergone some changes over the years. One of these changes was the size of the herd, although its scale varied from country to country. Various factors such as cost, profitability and ease of solving possible problems are taken into consideration while deciding on the size of the herd in the planning phase of the investment. This study was carried out to determine the effect of herd size and use of different bedding materials on health and milk yield in Turkish dairy herds. A total of 44 dairy farms were used in the study, and all of them were free stall. Farms were grouped into three herd size categories; small (with less than 30 cows), medium (30 to 50 cows) and large (with more than 50 cows). 305-day milk yield data were collected at the end of lactation period from the database of Cattle Breeders' Association of Bursa/Turkey. While health data (about dystocia, retained placenta, clinical mastitis and repeat breeding) were collected from the herd records, locomotion scoring was done by the researchers. The effects of herd size on repeat breeding, locomotion score, mastitis and milk yield were found significant. Bedding materials were examined in three different types (rubber, sand or without bedding-concrete surface) and their effects on repeat breeding, locomotion score, mastitis and 305-day milk yield were also found significant. The large size herds had higher milk yield (6993.24 +/- 72.52 L) and better herd health than small and medium-size herds except for the repeat breeding and also, milk yield (7235.60 +/- 110.94 L) and herd health were better in herds that used rubber bedding than concrete and sand except for the repeat breeding and dystocia. Consequently, herd health and milk yield were significantly affected by herd size and the bedding material that was used.Publication Relation between non-infectious factors and neonatal calf health status in dairy herd(Wiley, 2020-01-01) Kara, Nurcan Karslıoğlu; KARSLIOĞLU KARA, NURCAN; Ziraat Fakültesi; Zootekni Bölümü; ABB-3323-2020The aim of this research was to determine some non-infectious factors (sex of calf, calf birth weight, calving season and dam parity and dam body condition score at dry and calving) that can under control by breeders affecting calf health status (CHS) in neonatal period. A total of 517 calves (from delivery of calf until 28 days) and their dams (at dry and calving) were assessed according to study criteria. Relationship between CHS and dam parity (DP), body condition score at calving (BCSC), body condition score at dry (BCSD), sex of calf (SC), calf birth weight (CBW), and calving season (CS) was examined and connection between CHS and BCSD, CS, and CBW was found important. Also, influences of DP, SC BCSC, and BCSD on CBW were examined and while effects of DP and SC on CBW were found important, effects of others were not. These results show that relation between CHS and CBW, CS, and BCSD is important and CHS is higher in female calves or calves born to multiparous dams. As a conclusion, it can be said that planning the herd management practices according to these results will be beneficial for the healthier completion of the neonatal period.
