“…Under conditions of quantitative and qualitative limitations on grazing, these demands are generally not completely met, with the cows using their body reserves (Bohnert et al, 2013) to maintain production, affecting their performance as a result. While the cows are still growing, this may be aggravated by the greater body size of the cows and, consequently, their greater nutritional demand (Farias et al, 2018a), which can influence reproduction (Farias et al, 2018b;Bitencourt et al, 2020), or by the demands of growth competing with and affecting the reproductive performance and productivity of the herds, even when maintained under good nutritional conditions (Castilho et al, 2018).…”
