Effects Of Feeding Brewers’ Spent Grains On The Performance Of Growing Pigs In Rwanda

ABSTRACT

Livestock production is one of the major sources of income in Rwanda. Pigs are among preferred livestock due to their short generation interval and small space requirement. Feeds account for 65-70% of total production costs in pig rearing, which invariably affects profit margins. Therefore search for alternative feedstuffs that are locally available and affordable like brewers’ spent grains (BSG) can be used to feed pigs and reduce the cost of production. BSG is the first solid material by-product that remains after barley grain has been fermented during the beer making process. This study evaluated the nutrient composition, effect and economics of substituting sow and weaner meal (SWM) with BSG on the performance of growing pigs in Rwanda. A feeding trial was conducted using 30 gilts of Landrace x Pietrain cross weighing 30 - 40±5kg. A completely randomized design (CRD) was used in which pigs were randomly allocated to 10 pens based on initial weight with 3 pigs per pen. Five treatments of BSG replacing SWM at a rate of 0% (T1), 25% (T2), 50% (T3), 75% (T4) and 100% (T5) were randomly assigned to pigs for 42 days. Weekly data on average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR) and net returns (based on the variable costs of production) was collected. Proximate analysis showed that nutrient composition of BSG and SWM differed significantly (P
