Avaliação do maneio alimentar do gado bovino de corte no Centro Universitário de Changalane - CUC, na província de Maputo, distrito de Namaacha

Abstract

The work was developed with the purpose of evaluating the productive efficiency of beef cattle supplemented on natural pasture. Ten uncastrated Nguni steers, aged between 20-24 months and months and mean live weight (MFW) at the start of the study of 280 kg were subjected to two (1) in the first 60 days the calves were integrated into the feeding system used in the system used in the unit together with the other animals of the cattle herd In the last 30 days the calves were subjected to a grazing and supplementation system. the pasture feeding system and supplementation with a concentrate where they each received 2 kg of supplement before going to pasture and 2 kg per animal after grazing and water ad libitum. A pasture area of about 200 ha was demarcated and the botanical composition botanical composition, availability of pasture, stocking density and carrying capacity were determined. The pasture had a lot of uncovered area (42%), a lot of shrub invasion (14%) (mostly acacia) dead material (11%) and a grass composition of about 33% with dominance of Themeda triandra(15%), followed by Setaria sphacelata(7%), Aristida adscensionis(5%), Panicum maximum(4%), etc. The pasture availability found was 909.2 kg of DM/ha, corresponding to a stocking density and carrying capacity of 0.2UA/ha and 5 ha/UA, respectively. The average daily gain (ADG) was determined and compared between the two between the two feeding systems was determined and compared. It was observed that there was a statistically superior performance between the two between the two treatments.
