Rumen Undegradable Protein

Embryo survival rate is a major factor determining litter size and overall reproductive efficiency in sheep. In sheep, as ovulation rate increases the proportion of embryos surviving decreases. There is evidence, from cattle, that feeding a rumen-undegradable protein supplement enhances embryo survival rate. The objective of this experiment was to determine the effect on embryo survival rate in high prolific ewes of feeding an energy or protein supplement.

The experiment was performed with 21 Ayshire cows 4—16 weeks post calving. Cows received restricted amounts (according to calculated intake) of unwilted grass silage, preserved with a mixture of acetic acid and formalin and two kilograms of hay/cow/day. A concentrate mixture including dried and propionic acid treated barley and oats together with a mineral-vitamin mixture was given 0.3 kg/kg FCM. During the standardization period (2 weeks) protein feeding of the cows was performed according to the DCP requirements and the diet was supplemented with soybean meal if necessary. For the adaptation period (3 weeks) and the comparison period (8 weeks) the cows were divided in 3 equal groups of 7 cows (G1, G2, G3). G 1 had no protein supplement in the diet. The diets of G 2 and G 3 were supplemented correspondingly either with rapeseed meal or formaldehyde treated urea on the basis of the UDP (undegradable feed protein) requirements (G2) and the DCP requirements (G3) of the cows. Efficient protein degradabilities in the total diets during the comparison period varied from 77 to 85 % when the determinations were made with the nylon bag technique. The highest degradabilities were found for the diet of G3 and the lowest for G 2. Significantly (P < 0.05, 0.01) the highest yields of FCM and milk protein were recorded for Group2 (G2) in which the cows received protein supplement according to their UDP requirements. Using a factorial approach, conversion of protein absorbable in the small intestine to milk protein was calculated to be 66.5 ± 0.8 % when all the cows in three groups were taken into account.

The objectives of this study were to evaluate the effect of differences in protein type and delivery method on rumen dynamics and nutrient digestion. Cows were allotted to rumen degradable protein (RDP) or rumen undegradable protein (RUP) and self-fed (SF) salt-limited pressed blocks or hand-fed (HF) loose supplement, resulting in four dietary treatments. There was a delivery effect (p = 0.04) on neutral detergent fiber (NDF) intake, as the SF animals consumed more NDF than HF animals. The RDP-SF animals had greater NDF digestibility (p = 0.04) and water intake (p = 0.03) than the three other treatments. Supplement intake displayed a protein type effect (p = 0.03), as RDP-supplemented animals consumed more supplement on a g·kg body weight (BW)−1 d−1 basis than RUP animals. There was an effect of protein type (p = 0.02) and delivery method (p = 0.03) on fluid flow rate, with RUP and HF cows having greater liquid flow rates. Ruminal pH was lower (p < 0.01) in RDP-HF cows than RDP-SF cows at all hours, except 4-h post-feeding. RDP-SF animals had the greatest (p < 0.01) concentrations of ruminal ammonia. Valerate ruminal concentrations were greater (p = 0.04) in RDP supplemented animals compared to RUP supplemented animals. In conclusion, self-fed supplements containing RDP may enhance the use of low-quality forages and increase ruminal ammonia concentrations.

Protein Degradability

Rapeseed meal is a common protein supplement in ruminant diets that is characterized by high rumen protein degradability (Bertilssonet al., 1994; Vanhataloet al., 1995). Appropriate treatment can however reduce ruminal protein degradability and increase the efficiency of protein utilization. RaPass (UM Feeds Marketing, Burton on Trent, Staffs, UK) is a commercial rapeseed meal product that made using the Maillard reaction. This is the non-enzymatic browning reaction between proteins and reducing sugars that protects protein from rumen degradation. Release of the protein at abomasal pH allows the peptide chains to be digested at an efficiency similar to that of untreated rapeseed meal (Mosset al2000). Cows fed rapeseed meal that was treated to increase the rumen undegradable protein (RUP) content have been reported to perform better than those fed untreated rapeseed meal (Bertilssonet al., 1994). This study evaluated the potential of using RaPass as a protein supplement in dairy cow rations.

Abstract As a novel oilseed crop in Florida, Brassica carinata has the capacity of producing high-quality jet biofuel, with a protein-dense meal (~40% crude protein; CP) obtained as a byproduct of oil extraction. Characterization of the meal protein is limited, yet necessary for formulation of beef cattle diets; therefore, the objective of this experiment was to determine ruminal and post-ruminal digestibility of protein from B. carinata. Eight ruminally-cannulated Angus crossbred steers (473 ± 119 kg) were used in a duplicated 4 × 4 Latin square design, in which in situ ruminal and post-ruminal degradability of nutrients were evaluated. The three-step in vitro procedure was used to compare CP and amino acid degradation in B. carinata meal pellets (BCM) with that of cottonseed meal (CSM), dry distillers grains with solubles (DDGS), and soybean meal (SBM). In situ bags were incubated in the rumen for 0 to 96 h, with the undegraded supplement remaining after 16 h subjected to serial in vitro enzymatic solutions. Data were analyzed using the MIXED procedure of SAS. Ruminal rate of degradation of dry matter, organic matter, and CP was greatest (P ˂ 0.01; 10.9, 11.3, and 11.5 %/h, respectively) for SBM. Rumen degradable protein content did not differ (RDP; P = 0.20; 47.8 and 55.1%, respectively) between CSM and DDGS, but was decreased (P ˂ 0.01) compared with SBM and BCM, which did not differ (P = 0.99; 72.3 and 71.8% RDP, respectively). Compared with DDGS, SBM had greater (P &lt; 0.01) intestinal digestibility of rumen undegradable protein (RUP). Intestinally absorbable digestible protein (IADP) was greatest (P &lt; 0.01) for CSM, with SBM and BCM having the least IADP. Total tract digestibility of CP (TTDP) was greater (P &lt; 0.01) for SBM compared with CSM and DDGS. The contribution of RUP to intestinally absorbable amino acids was 7.2 and 3.1 g of lysine and methionine per kilogram of CP in BCM, respectively. The evaluation of Brassica carinata meal as protein supplemented for cattle consuming a forage-based diet resulted in 71.8% RDP and 97.1% TTDP, thus indicating its viability as a high-quality protein supplement for beef cattle.

Abstract A two-yr study was conducted to evaluate the effects of monensin on sparing ruminal degradable protein in yearling steers grazing smooth bromegrass pastures (n = 288, initial BW = 332 kg, SD = 7). Treatment design was a 2 x 3 factorial with the following factors: 1) 0 or 200 mg monensin/steer daily; 2) no protein supplement, 1.25 kg soybean meal (SBM) as a source of RDP, or 1.31 kg non-enzymatically browned SBM as a source of RUP. Steers receiving supplemental protein were provided isonitrogenous amounts equivalent to dried distillers grains plus solubles at 0.50% BW. Steers were weighed approximately every 34 d to adjusted the amount of protein supplement. There was no interaction (P &gt; 0.41) of monensin by protein type for average daily gain (ADG). Rate of gain for steers supplemented monensin was not different (P = 0.26) from steers not supplemented monensin. However, monensin supplemented steers numerically gained 7.9% more than steers not provided monensin when no supplemental protein was provided. Compared to steers supplemented with no protein, supplementing RDP increased ADG by 0.19 kg/steer (P &lt; 0.001). Likewise, RUP supplementation increased ADG by 0.24 kg/steer (P &lt; 0.001) compared to steers supplemented no protein. Supplementing RUP increased ADG by 0.05 kg/steer (P &lt; 0.001) compared to steers supplemented RDP. Supplementing protein, especially rumen undegradable protein, improved yearling steer rate of gain on smooth bromegrass pastures. Monensin supplementation did not improve rate of gain. These data do not support the protein-sparing effects of monensin for steers supplemented with RDP.
