Abstract
The objective of this experiment was to assess the nutrient quality of locally available
feed ingredients for feeding ruminants in Anuradhapura district, Sri Lanka. Agroindustrial by-products such as rice (Oryza sativa) bran, maize (Zea mays L.) meal,
coconut (Cocos nucifera) poonac and soya bean (Glycine max) meal and different fodder
species such as maize (Zea mays), sorghum (Sorghum bicolor), CO3 (Pennisetum
purpureum), guinea grass (Panicum maximum) and Gliricidia (Gliricidia sepium) were
used. The chemical composition of the above ingredients was determined according to the
association of official analytical chemists. The ingredients were analysed for dry matter
content, crude protein, crude fiber, ash, ether extract, and gross energy content. From the
tested ingredients, soya bean meal (50.56±0.25%), coconut poonac (19.39±0.25%), and
Gliricidia (23.78±0.79%) had comparatively higher crude protein contents. Rice bran
(4219±209.30 kcal/g), Gliricidia (4066.50±0.71 kcal/g), sorghum (3882±39.60 kcal/g),
coconut poonac (3877±66.47 kcal/g), and soya bean meal (3714±33.94 kcal/g) had higher
gross energy contents compared to the other feed sources. The highest ash (10.70±2.02%)
and crude fiber (38.72±1.48%) contents were reported in sorghum. Relatively higher
ether extract content was observed in rice bran (11.48±1.48%), coconut poonac
(7.16±0.40%), Gliricidia (4.64±0.04%), and maize meal (3.12±0.99%). The present
results show that industrial by-products and different fodder species vary in chemical
composition. According to the available nutrient composition, these feed ingredients can
be used for feeding ruminants. Therefore, there is a possibility of preparing a total mixed
ration using these ingredients.
