Manipulation of rumen fermentation by use of microbial feed additivesmicrobial
MANIPULATION OF RUMEN MICROBIAL
FERMENTATION BY USE OF MICROBIAL FEED
Low Milk Production
Low Profitability (Afzal, 2007).
Lack of use of microbial feed additives in animal
feed (Thang, et al 2009).
Imbalanced Feeding scheme to animals (Sarwar, 2010).
Poor understanding of Microbial-Feed interaction
(Marden et al., 2008)
Our economy is mainly dependent on agriculture.
Livestock is second important sector of agriculture which
accounts for 52.20 % of the agricultural GDP (Economic survey
The country, at present contains 29.56 million cattle, and
27.30 million buffaloes (Livestock Census, 2006).
Besides that, in Pakistan per head milk yield is still much
less (30%) as compared to the milk production of dairy
breeds of the developed world (Sarwar, 2010).
Why Low Production??
The average age of puberty in animals is 34 months in
Pakistan which is higher than (7 months) any exotic breed
Imbalanced feeding program has been identified as major
cause of higher pubertal age resulting in low production in
pakistan ( Jabbar et al., 2006).
So far, little work has been done with an objective to
reduce the pubertal age of animal by application of
microbial feed additives (Jabbar , 2008).
Approaches to Resolve the Problems of Low
1. Understanding the Microbe-feed Interaction
2. Use of Microbial Feed Supplements
Main goal of dairy cow nutrition
1. In ruminant increase in the microbial number
in the rumen seems to be central to the
action of the yeast.
2. More information is now needed on the
mechanisms by which yeast stimulates
