| Abstract | Rumen microbial protein can be considered as a major source of protein (amino acids)
for the host animals. A possible alternative for providing soluble protein for host animals is
rumen by-pass protein. Therefore, the procedure for increasing ruminal by-pass of protein is
received much attention. As formaldehyde is the most important chemical treatment that has
been used to treat feed protein, the effect of formaldehyde-treated soybean meal protein on
sheep performance was evaluated during 10 weeks period, using completely randomised
design (CRD) with 4 treatments and 4 replication.
Sixteen fat tail sheep, approximately 10 - 14 months of age with body weight
ranging from 9 - 16 kg were used in this experiment. Soybean meal was treated with various
concentration of formaldehyde, i.e. thirty gram of 13.33 %, 26.67 % and 40 % formaldehyde/
kg soybean meal. Untreated soybean meal was used as the treatment control. Maize forage (zea
mays) was given ad-libitum as basal diet.
Treatment with highest formaldehyde levels enhanced live weight gain (19.27 kg), d1y
matter consumption (412.80) and feed efficiency (35.52 %). Similar effect were found on
carcass weight (8.78 kg) and carcass percentage (44.33 %). Ammonia-N, urea-N and glucose
concentrations declined at 40 % formaldehyde treatment. Number of protozoa and pH in the
rumen showed that mean value range from 6.34 - 6.43 and 6.25 - 6.59 x 105 /ml respectively.
The result indicated that, formaldehyde treatment ( 40 % at 3 % w/w) of soybean meal
protected dietary protein from rumen micro-organisms. Further investigation the optimum
level of formaldehyde is warranted. |
