“…The increase in the apparent digestibility of CP in the diets L-40 and H-40 as compared to diets L-30 and H-30, in both species, could result from the higher level of undegraded protein used in these diets. These figures indicate that the post-ruminal digestibility of the undegraded protein, both in buffalo and sheep, is higher than that from protein of microbial origin as had already been indicated by Bruckental et al (2002) for the dairy cow; however these latter Authors, with a different species and under different physiological condition, obtained a digestibility of the microbial protein inferior to ours. Moving on to examine the nitrogen balance, for the buffalo species the difference in digestible protein between the average of the diets H-40 + L-40 vs. H-30 + L-30 is 5.00 g/day, equal to a saving of 50.14 g/head/day of dry matter; while for the sheep, using the same procedure, one obtains a difference of 1.65 g/day of digestible protein, equal to a saving of 12.50 g/head/day of dry matter.…”

“…The digestibility of non-structural carbohydrates, in the buffalo, presents a significant difference between the two diets at the high and low energy level (90.59%, 89.46% vs. 85.95%, 85.81%, P b 0.05) whilst in sheep there is a significant difference only between diet L-40 and the diets H-30 and H-40 (87.62% vs. 83.16%, 83.77%, P b 0.05). For sheep there is a 1.46% increase in the digestibility of the NSC between the diets L-40 and L-30; Bruckental et al (2002) in lactating cow using diets with 41% and 46% UDP found, with respect to the diet with 36% UDP, an increase in digestibility of the total non-structural carbohydrates (TNC) of 2.0% and 2.4%. Therefore while the presence in the diet of the buffalo of 30% or 40% of UDP does not appear to alter the digestibility of non-structural carbohydrates, on the contrary in sheep there is a positive effect with the diet L-40 with 41% of UDP, and also to a more limited degree with the diet H-40 (+ 0.61%).…”

“…These characteristics result in the fact, as already asserted by Di Lella et al (1995) that the percentage of crude protein of foodstuff origin (21 different feeds), in buffalo compared with sheep, at maintenance level, that escapes fermentation in the rumen and becomes absorbed at the intestinal level, is limited. Taniguchi et al (1993) have shown that in sheep the digestibility of starch increases with the increment of protein digested in the small intestine; Bruckental et al (2002) sustain the opinion that more protein in the small intestine enables a higher secretion from the pancreas of the enzymes responsible for the digestion of starch.…”

“…Moreover, the rumen-undegradable protein and non-structural carbohydrate intakes could also affect nutrient digestibility. Bruckental et al (2002) found that the digestibility of CP and non-structural carbohydrate increased when the proportion of undegradable protein was increased. Table 4 shows the result of rumen fermentation efficiency influenced by Hipro-feed formulated in concentrate mixture in lactating dairy cows.…”

The aim of this study was to investigate the effect of high protein feed (Hipro-feed) formulated with carbohydrate source in concentrate mixture on feed intake, rumen fermentation, and milk performance of lactating cows fed Ruzi grass. Sixty cross-bred dairy cows (75% Holstein-Friesian and 25% Thai cows) in mid-lactation, 390 ± 50.0 kg body weight, 85 ± 5 days in milk with daily milk production of 10 ± 2.0 kg/day, were selected from 15 smallholder dairy farms and assigned according to a randomized complete block design. Four cows per farm were subjected to two groups to receive dietary treatments: Formulation I = control formula used by farmers and Formulation II = Mixed carbohydrate source + Hipro-feed (48% crude protein). The results showed that cows that received Formulation II had higher total feed intake and nutrient digestibility (P < .05). However, ammonia nitrogen, total volatile fatty acids, and propionic acid were increased in cows that consumed Formulation II, while acetic acid and butyric acid, ruminal pH, temperature, and blood urea nitrogen were similar between groups. Milk yield and economic return were increased in cows receiving Formulation II. In conclusion, Hipro-feed could usefully be incorporated with carbohydrate source in concentrate formulation for the improvement of diary performance of smallholder dairy farming in the northeastern region of Thailand.

“…Thus, this suggests a negative effect on ruminal starch degradability when removing ruminal N provided by the SS supplement, although the basal diet was providing substantial soluble N from silage. In contrast, higher total tract digestibility of total non-structural carbohydrate was observed when dietary undegradable CP was increased (Bruckental et al 2002) or following abomasal infusion of casein (Richards et al 2002). Apparent digestibility of NDF tended to be lower (P 00.07) and was numerically lower for ADF for GC than for CC supplemented diets (Table 4).…”

Amours, M. and Berthiaume, R. 2008. Feeding strategies for improving productivity of growing steers fed grass silage. Can. J. Anim. Sci. 88: 685Á692. Two experiments were conducted to determine the relationship between corn particle size and soybean meal treatment on growth, diet digestibility, and nitrogen balance of growing steers. In the first experiment, 40 medium-frame beef steers (250911 kg) were fed individually for 140 d a diet based on grass silage offered for ad libitum consumption and supplemented with either 3.5 kg of DM d(1 of cracked corn (CC) or ground corn (GC) and with 450 g of DM d(1 of solvent extracted (SS) or lignosulfonate-treated soybean meal (Soypass TM ; SP). Dry matter intake was not affected by treatments and averaged 8.690.3 kg d (1 (P0.10). Average daily gain was higher for animals receiving the ground corn than those fed cracked corn. Feed to gain ratio was not affected by treatments. There was an interaction between treatments for plasma urea-N concentration, with source of soybean meal having no effect with CC. When compared with SS, SP supplement reduced plasma urea-N when fed with GC. No effect of soybean meal and its interaction with corn processing was observed on growth performance. In the second experiment four additional steers were used in a 4 )4 Latin square design to evaluate diet digestibility and nitrogen balance. There was an interaction between treatments for starch apparent digestibility and N retained, the values being respectively, 90, 86, 93, and 92% (SEM 01.2; PB0.01) and 36, 42, 44 and 41 g d(1 (SEM02.8; P B0.03) for CCSS, CCSP, GCSS and GCSP, respectively. Altogether, the results indicate a slight advantage to reduce particle size of corn in growing steers fed grass silage. However, soybean meal treatment resulted in limited effects on growth and digestion. e´alise´es pour de´terminer la relation entre la taille des particules de maı¨s grain et le traitement du tourteau de soya sur la digestibilite´de la ration, la croissance et le bilan azote´de bouvillons.
