Four rumen-fistulated cows were fed concentrate:corn silage (40: 60) diets in a 4 × 4 latin square design experiment. The diets differed in the soybean meal or soybean meal treated with 0.1, 0.3 or 0.6% (wt/wt) formaldehyde. Rumen contents were collected hourly from 0900 h to 1600 h with an additional sample at half an hour after the 1100 h feeding on 3 days in the second week of each 2-wk experimental period. The maximum ammonia concentration in rumen contents decreased with increasing levels of formaldehyde used to treat the soybean meal. From 1130 to 1200 h the rates of ammonia appearance in the rumen contents were different (P < 0.05) for all four diets. Treatment of soybean meal with between 0.1 and 0.3% (wt/wt) formaldehyde reduced its in vitro degradation by rumen protease by about 50% compared with the untreated control. The rates of in vivo ammonia appearance and in vitro proteolysis were highly correlated (r = 0.966, P < 0.01) between 1130 h and 1200 h. These rates of rumen ammonia appearance reflected the in vivo rate of proteolysis. Both bacterial and protozoal protein content decreased significantly at the higher levels of formaldehyde treatment. There was a negative correlation (r = − 0.63, P < 0.01) between protozoal and bacterial protein. Key words: Formaldehyde, soybean meal, bovine, rumen, degradation, protease

This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.
