Description The effect of replacing commercial supplements with isoenergetic and isonitrogenous velvet bean-, cowpeaand
lablab-based supplements on milk yield, milk quality and economic returns in smallholder crossbred dairy
cows was investigated in the 2013 and 2014 dry seasons. Using 3 × 3 Latin square designs, nine multiparous
Red Dane, Guernsey and Holstein-Friesian crosses in mid-lactation (130 ± 19 d) were offered forage legume-based
supplements for 63 d at 0.5 kg per litre of milk produced. Milk quantity and quality were significantly (P < 0.05)
different among supplements in both seasons. Cows fed commercial supplements had higher milk yield than
cows fed forage legume supplements. Milk fat content was significantly (p < 0.05) higher in cows fed lablabbased
supplements than cows fed other supplements. Milk protein, total solids and lactose content of cows fed
commercial supplements was significantly (p < 0.05) higher than those fed forage legume-based supplements,
although protein content was similar to cows fed lablab-based supplements. Dietary gross margins were higher
for cows fed velvet bean- and lablab-based supplements by 17% and 16.5%, respectively. Based on supplement,
production costs per litre of milk was higher by 28% and 23% using commercial supplements compared to velvet
bean and lablab supplements, respectively.
