“…However, Kumar et al (2022) observed non-significant effects on LMY in Sahiwal cattle. Non-significant effects on LMY, ADMY and LL for Kankrej cattle were observed by Thakkar et al (2021). The presence of significant seasonal effect on LMY, ADMY and LL might be an indication of the difference in management practices and availability of feeds and fodder during different seasons.…”

Binjharpuri, a dual purpose indigenous breed of Odisha is commonly reared for its various advantages, viz. optimum milk production in low input management system, excellent draft ability in hot humid climate condition and heat resistance ability. In the present study, attempt was made to evaluate production performance along with influence of non- genetic effects such as location, lactation order and season of calving on production traits of binjharpuri cattle. The overall average least square means along with standard error for lactation milk yield, average daily milk yield, peak yield, lactation length and dry period were found to be 974.490±6.788 kg, 3.557±0.023 kg, 4.633±0.021 kg, 274.444±1.249 days and 121.913±0.611 days, respectively. Location had highly significant effect on lactation milk yield, average daily milk yield, lactation length and dry period, whereas non-significant effect on peak yield. Lactation order too had highly significant effect on the traits considered under study. Season of calving had highly significant effect on lactation milk yield, average daily milk yield; significant effect on lactation length whereas non-significant effect on peak yield and dry period. Significant influence of non-genetic factors and significant variations in traits under study is suggestive that remarkable improvement in the Binjharpuri cattle populace can be targeted through better management and by nurturing effective breeding strategies.

This study investigated the impact of parity, period of calving, and season of calving on various production and reproduction traits in Hardhenu cattle. Third‐parity cows outperformed first and second‐parity cows, exhibiting significantly higher total milk yield (TMY), 305 days milk yield (305d MY), peak yield (PY), and artificial insemination per conception (AIPC) (p < .01). The Lactation length (LL) was inversely related to parity, with first‐parity cows having extended lactations (p < .05). The period of calving had a substantial influence on production traits. The season of calving was critical, affecting production traits differently across parities. First‐parity cows had the highest TMY and 305d MY during winter and summer calving, with summer calving associated with shorter LL (p < .05). Second‐parity cows showed higher TMY and 305d MY during summer calving, while third‐parity cows had higher TMY in winter (p < .01). PY followed similar patterns to TMY, with LL affected by the season of calving. Additionally, the study explored interactions between parity, period of calving, and season of calving on reproduction traits. Third‐parity cows had higher AIPC compared to first and second‐parity cows (p < .01). Reproduction traits were also significantly affected by the period of calving, with cows calving in the 2017–2021 period displaying longer service period (SP), calving interval (CI), dry period (DP), and AIPC (p < .01). These findings highlight the complex interplay of biological, environmental, and management factors in shaping the productivity and reproductive efficiency of Hardhenu cattle, emphasizing the need for multifaceted considerations to optimize herd performance.

“…Among genetic and non-genetic factors that influence the cows' dairy productivity, the following factors have been proved to have a strong influence, namely: the sire group (Choudhary et al, 2019;Thakkar et al, 2021), lactation number, i.e., the cow's age (Gorgulu, 2011;Bolacali & Öztürk, 2018;Marumo et al, 2022), cow age at first insemination or first pregnancy (Gorgulu, 2011;Eastham et al, 2018;Adamczyk et al, 2018), a season of the year (ElBoshra et al, 2016), the inter-calving interval (Němečková et al, 2015;Bujko et al, 2018), dry period length (Gorgulu, 2011), and others.…”

The main aim of our research was to determine the effect of origin and generation on the fractal dimension values of the milk production peculiarities in dairy cows. This study analyses data from cattle milk production at the LLC "Promin", Mykolaiv region. We formed four experimental groups of first-calf Holstein heifers of different origins and generations. The animals of the first group were imported from Germany; the second group was their offspring; the third group was Ukrainian breed cows, and the fourth group was their offspring. We assessed 305-day milk yield, total milk yield, milk fat percentage, milk fat yield, milk protein percentage, milk protein yield and lactation length for each cow. The information fractal dimension (FD 1 ) values were calculated for each trait within each group. The fractal dimension values in all groups for 305-days milk yield, milk fat and milk protein yields were close to 1 (excluding the fourth group); thus, it can be argued that the random mechanism of their regulation and, accordingly, the lack of fractal properties. The estimated FD 1 values for total milk yield were slightly lower; they fluctuated within very narrow limits in all groups and did not depend on either origin or generation. In addition, the calculated FD 1 values for total milk yield were significantly lower than the corresponding estimates for 305day milk yield in all cow groups. The use of fractal analysis revealed significant differences, which are based on different regulation mechanisms of the milk fat percentage in cows of the daughter generations. On the other hand, the fractal dimension values FD 1 for milk protein percentage did not differ significantly between mothers and daughters, regardless of their origin. It was also found that the control for lactation length in the daughter generation was lower than the maternal one. Thus, using fractal analysis to study the regulatory mechanisms of milk production traits in dairy cows allowed us to determine the influence of the origin and generation (mother or daughter).
