Performance of Goat Kids Fed Sorghum Sudangrass and Pearl Millet Regrowth
The objective of this study was to determine the performance of goat kids fed sorghum sudangrass/pearl millet mixed with legumes. Twenty goat kids (bodyweight 25.5 +/- 5.1 kg) were randomly assigned to four treatments (5 kids per treatment). The treatments were: (i) sorghum sudangrass + low mix (SLM; Control), (ii) pearl millet + low mix (MLM), (iii) pearl millet + high mix (MHM), and (iv) pearl millet + low mix + cow pea (MLC). All treatments also received alfalfa hay. The kids were housed in four pens (3.6 m x 6.1 m each); two kids within each pen were considered one experimental unit. Forage was cut manually and chopped into smaller pieces before feeding. Water and mineralized salt blocks were provided free choice. Goat kids on SLM treatment had the greatest (P < 0.05) average daily gain (ADG; 147 g/d) followed by MLC (126 g/d) and MLM (117 g/d) kids. The MHM kids had the lowest ADG (65 g/d). Similarly, SLM kids had the highest (P < 0.05) feed efficiency (7.4:1) followed by MLC (9.1:1) and MLM (9.8:1). Sorghum sudangrass was shown to be more nutritious for the goat kids than pearl millet. Future research should investigate the most optimal plant growth stage and legume combinations that can provide quality feed for kids in this growth phase.
