Resumen
SUAREZ PATERNINA, Emiro Andrés et al. Daytime Ingestion Behavior and Performance in the Production of Lambs Supplemented with Cotton Seed and Ground Corn (GC). Rev. Med. Vet. [online]. 2019, n.39, pp.63-74. ISSN 0122-9354. https://doi.org/10.19052/mv.vol1.iss39.7.
The study of the ingestion behavior is important to know the animal production performance and is a must when evaluating different feeding regimes. This work aims to evaluate the daytime ingestion behavior and the productive answer in criollo lambs receiving supplement with cotton seeds (CS) and ground corn (GC). Sixteen complete male criollo lambs were used having a starting weight of 16 ± 2 Kg. They were distributed randomly into four experimental treatments consisting in: T0 = shepherding, T1 = shepherding + 25% CS + 75% GC, T2 = shepherding + 50% CS + 50% GC, and T3 = shepherding + 75% CS + 25% GC. Using both external and internal markers, the nutritional composition of the forages and the dry mass consumption in the animals were determined, i.e., the ingestion behavior and the productive performance. The total dry mass consumption showed statistical differences (p < 0.05), with lower consumption among the control animals. Likewise, statistical differences were detected (p < 0.05) between the treatments for shepherding activities, cud, water consumption and walking regarding variables like mouthfuls per minute and total ingestion. The final weight and the weight gain in the animals receiving supplements were higher in 28.4 % and 50.3 %, respectively. The CS and GC supplements led to a greater consumption of nutrients and, therefore, improved the ovine production performance.
