Abstract

The objective was to evaluate the replacement of corn by Parkia platycephala in multiple supplements on the ingestive behaviour of sheep and the productive, structural characteristics, and nutritive value of Tamani grass pastures during the rainy season. A randomised block design with four treatments was used (Mineral salt; Mineral salt + urea; Parkia P. and Soybean + corn). At the end of the rest period, Tamani grass was 64.34 cm tall and had a light interception of 95.76%. Total forage production pre-grazing was 2586 kg/ha, with no stalk fraction in the collections. It was observed that pre-grazing crude protein was 111 g/kg. The fiber content of simulated grazing increased on the last day of occupancy, reducing the effective degradability of the material. The longest grazing time and trough consumption occurred on the first day of occupancy, and regardless of the day of occupancy, animals supplemented with PARKIA P. and SOYBEAN + CORN grazed less. The regrowth of Tamani grass must be stopped when it reaches around 64 cm, and the acorn bean pod can be used to formulate concentrated supplements that replace 50% of the corn. © 2025 The Royal Society of New Zealand.
