“…In a study in Turkey, Guzel et al (2012) determined serum leptin levels in Brown Swiss (2.35±0.34 ng/ml), Holstein bulls (3.55±0.53 ng/ml), Avesi sheep (2.16±0.29 ng/ml), saanen (2.23±0.46 ng/ml) and hair goats (0.94±0.10ng/ml) by the radio immune assay (RIA) method. In the early 2000s, studies investigating leptin levels serologically were more common, but in the following years more genetic studies began to gain importance (Ferchichi et al, 2018;Kaplan, 2018;Abbas et al, 2019;Avondo et al, 2019;Das et al,2019;Ibrahim et al, 2020;Mahrous et al, 2020;Sedykh et al, 2020).…”

Leptin is a hormone that provides the central and/or peripheral regulation of food intake, energy expenditure, whole body energy balance, fertility and immune functions by creating a feeling of satiety in animals and humans. This study was carried out to determine serum leptin values for some ruminant species and breeds that were healthy and had at least one birth. In the study, 15 Simental and 15 Holstein cows, 15 Italian buffalo, 15 Pırlak sheep, 15 Honamlı and 15 Turkish hair goats were used as material. Serum leptin concentrations were measured with the BT LAB Bovine Leptin ELISA kit. Serum leptin levels were determined as 2.78±0.22 ng/ml in Simmental cows, 2.87±0.11 ng/ml in Holstein cows, 3.6±0.48 ng/ml in Pırlak sheep, 3.38±0.76 ng/ml in Honamlı goats, 5.48±0.92 ng/ml in Hair goats and 2.50±0.17 ng/ml in Italian buffaloes. As a result, it was determined that serum leptin levels obtained from different ruminant species that were healthy and gave at least one birth in Burdur province were within the reference values reported for ruminants.

Increased productivity in the industry can be achieved by breeding for productive longevity through searching and using genetic markers. The study analysed the data of 1476 animals with at least one completed lactation. Depending on the linear affiliation and kappa-casein gene genotype of servicing bulls, their female offspring were divided into 4 groups. The CSN3 A allele frequency in the studied bulls was 81.91%, the CSN3 B allele was 18.09%. The highest frequency of the desired CSN3 B allele in the servicing bulls-producers of the Reflection Sovering line was 20.83%, which is 3.69% more than in the bulls of the Vis Back Ideal line. The animal life length analysis showed that the female progeny of bulls from the Reflection Sovering line (2.46 lactation), especially those with the CSN3 AB genotype (2.59 lactation), had the longest life. The offspring of CSN3AB genotype bulls of the Reflection Sovering line had the highest lifetime milk yield (18490 kg). The CSN3AB genotype cows of the Reflection Sovering line had the highest average milk yield on the 1st day of a cow’s life of 9.05 kg.
