The study aimed to evaluate the effect of four levels of coconut cake inclusion (0, 10, 20, 30%) in the diet of guinea pigs on productive parameters during the growth and fattening phases. Four hundred male guinea pigs from the Peru genetic line were used, with an average age of 14 ± 3 days and an initial weight of 294.8 ± 4.0 g. The animals were randomly distributed into four experimental groups, each with five replicates of 20 guinea pigs, for 56 days. Key indicators such as daily weight gain (DWG), final weight (FW), feed consumption (FC), feed conversion ratio (FCR), carcass yield (CY), and economic return were recorded. No significant differences were found in the production parameters analysed (p>0.05), with average values for DWG, FW, FC, FCR, and CY between 12.6 and 13.0 g/day, 995.1 and 1020.8 g, 2161.4 and 2471.2 g/guinea pig, 3.02 and 3.49, and 73.06 and 73.64%, respectiv...

The aim of this study was to evaluate the dynamics of growth and nutritional value of Pennisetum spp (cv. Maralfalfa) at three cutting ages (45, 60 and 75 days) and at two times of the year (high and low rainfall) in the district of Oxapampa, Pasco, Peru. Plant height to flag leaf (AH), number of tillers (NT), green biomass (BV), dry matter (DM), in vitro digestibility of dry matter (DIVMS), crude protein (CP), crude fibre (CF), calcium (Ca) and phosphorus (P) were evaluated in a completely randomized design with a 3x2 factorial arrangement (cut-off age and time of year). The AH did not present significant differences for age at cutting (34.27±4.00, 210.08±4.00 and 251.14±4.00 cm for 45, 60 and 75 days, respectively), nor between seasons (191.91±3.26 and 205.09±3.26 cm in low and high precipitation, respectively). The NT did not show significant differences for age at cutting (54.56...
