The objective of this study was to determine the associations between bulk tank somatic cell count (BTSCC) and herd management practices on dairy farms in Western Türkiye. The material of the study consisted of 81 registered dairy farms. The farms were visited at approximately one-month intervals. Somatic cell count was determined electronically in the milk samples. According to the average BTSCC values of the farms, two different BTSCC categories were created (low: ≤400 103 cells/ml with 40 farms and high: >400 103 cells/ml with 41 farms). A questionnaire form was created to determine the herd management practices. The...

Finding suitable animal cell sources for cultured meat production remains a major challenge and continues to attract significant scientific interest, particularly in the development of bovine cultured meat. These cells must demonstrate robust proliferative capacity and the ability to maintain stemness. In this study, we aimed to evaluate the proliferation capacity and morphological alterations of bovine satellite cells (bSCs) derived from the Brown Vietnamese cattle during long-term in vitro expansion. The results showed that bSCs possessed a high proliferative potential, sustaining over 20 passages. These cells retained the expression...

The aim of this study was to evaluate the effects of domestication and the associated rearing system and rearing conditions on the carcass traits of ducks, assessed on the basis of weight and yield parameters, including skinless carcass weight, skinless breast muscle weight, skinless thigh weight, skinless thigh muscle weight, and the corresponding yield parameters. The study included 20 wild mallard ducks (Anas platyrhynchos) living under natural conditions and 20 domesticated Cherry Valley ducks (Anas platyrhynchos domesticus) reared under intensive indoor production conditions with controlled lighting, temperature, and feeding...
Gompertz – Pütter – Gompertz: Resolving two centuries of debate on laws of biological growthOriginal Paper

The function of Gompertz (1825) can be derived from the growth equation of Pütter (1920), using the modified form proposed by Kühleitner et al. (2019). The genetic relative growth rate is derived as RG = dlnW/dt = BG.ln(AG/W). The genetic characteristics are AG, mature weight, and BG, the rate parameter; the state variable is weight, W. The integrated form is W = AG.exp[–exp–(G0 + BG.t)], where G0 = –ln[–ln(W0/AG)]...
