A stochastic animal life cycle simulation model for a whole dairy farm system model: Assessing the value of combined heifer and lactating dairy cow reproductive management programs.
Li M, Reed KF, Lauber MR, Fricke PM, Cabrera VE. Li M, et al. J Dairy Sci. 2023 May;106(5):3246-3267. doi: 10.3168/jds.2022-22396. Epub 2023 Mar 10. J Dairy Sci. 2023. PMID: 36907761 Free article.
The model accounted for incomes from milk, sold calves, and culled heifers and cows, as well as costs from breeding, AI, semen, pregnancy diagnosis, and calf, heifer, and cow feed. We found that the interaction between heifer and lactating dairy cow re …
