Productive parameters of dualpurpose cattle supplemented with unconventional feed in the humid Colombian Caribbean
Dual-purpose production systems (SPDP) are of great importance in the Colombian Caribbean region due to the socioeconomic contribution and food security for the population; however, the productive indicators are low, attributable to poor technological management and seasonality in production caused by reduced forage availability in the dry season. The objective of this study was to evaluate in SPDP cows from four farms in the municipalities of Córdoba and Bolívar, the effect of supplementation with balanced energy-protein diets based on agroindustrial by-products (DEP), compared to the diet offered by the producer ( DProd), on nutrient intake (CN), milk production (PL), daily weight gain (GDP), and days open (DA). Higher consumption (g/day) of protein (p=0.009) and ether extract (p=0.001) was found in cows treated with DEP compared to DProd in farms in San Carlos (SC) and Carmen de Bolívar (CB), no differences (p>0.05) in the consumption of NDT and ME (Mcal/day) between treatments. PL was higher in the groups supplemented with DEP in CB cows (p=0.035; 6.43 vs. 5.88 kg/cow/d) and in SC (p=0.008; 4.4 vs 3.7 Kg. animal/d). In the DEP diet, reductions were observed (p<0.05) between 17 to 51 in open days and higher ADG in SC cows (0.375 kg a/day); In addition, the pups older than 4 months in the BC, the ADG was higher with DEP (0.470 vs 0.407 kg/a/d; p<0.05). The use of balanced diets with by-products of the agroindustry is presented as a promising option to improve milk production and the productive parameters of dual-purpose cows and calves in herds of the Colombian humid Caribbean
