different microalgae species as a substitutive Protein feed for soya far bean meal in grass silage based dairy cow diets
Animal Feed Science and Technology, 2019Co-Authors: Marjukka Elina Lammine, Seija Jaakkola, Anni Halmemiesbeauchetfilleau, Tuomo Kokkone, Aila VanhataloAbstract:Abstract This experiment was conducted to evaluate different microalgae species as Protein Supplements in the nutrition of lactating dairy cows in comparison to soya bean meal. Four multiparous lactating Finnish Ayrshire cows (112 days in milk) were used in a balanced 4 × 4 Latin square study. Cows were fed separately fixed amount of cereal-sugar beet pulp based concentrate (12.5 kg/d) and grass silage ad libitum. Experimental treatments consisted of four isonitrogenous Protein Supplements: soya bean meal (SOY), Spirulina platensis (SPI), Chlorella vulgaris (CHL) and a mixture of C. vulgaris and Nannochloropsis gaditana (1:1 on dry matter (DM) basis; CHL-NAN). The substitution of soya bean meal by microalgae did not affect the quantity of total DM intake (DMI), but changed the composition of DMI by decreasing the concentrate:forage ratio of the diet (P = 0.054) owing to the poorer palatability of microalgae. Intake of methionine was increased (P

comparison of heat treated rapeseed expeller and solvent extracted soya bean meal as Protein Supplements for dairy cows given grass silage based diets
Animal Science, 2003Co-Authors: Kevin J Shingfield, Aila Vanhatalo, Pekka HuhtanenAbstract:Sixteen early to mid lactation Finnish Ayrshire dairy cows were used in a cyclic change-over experiment with four 21-day experimental periods and a 4 5 2 factorial arrangement of treatments to evaluate the effects of heat-treated rapeseed expeller and solvent-extracted soya-bean meal Protein Supplements on animal performance. Dietary treatments consisted of grass silage offered ad libitum supplemented with a fixed amount of a cereal based concentrate (10 kg/day on a fresh weight basis) containing 120, 150, 180 or 210 g crude Protein (CP) per kg dry matter (DM). Concentrate CP content was manipulated by replacement of basal ingredients (g/kg) with either rapeseed expeller (R; 120, 240 and 360) or soya-bean meal (S; 80, 160 and 240). Increases in concentrate CP stimulated linear increases (P < 0.05) in silage intake (mean 22.5 and 23.8 g DM per g/kg increase in dietary CP content, for R and S, respectively) and milk production. Concentrate inclusion of rapeseed expeller elicited higher (P < 0.01) milk yield and milk Protein output responses (mean 108 and 3.71 g/day per g/kg DM increase in dietary CP content) than soya-bean meal (corresponding values 62 and 2.57). Improvements in the apparent utilization of dietary nitrogen for milk Protein synthesis (mean 0.282 and 0.274, for R and S, respectively) were associated with higher (P < 0.05) plasma concentrations of histidine, branched-chain, essential and total amino acids (35, 482, 902 and 2240 and 26, 410, 800 and 2119 mu mol/l, respectively) and lower (P < 0.01) concentrations of urea (corresponding values 4.11 and 4.52 mmol/l). Heat-treated rapeseed expeller proved to be a more effective Protein supplement than solvent-extracted soya-bean meal for cows offered grass silage-based diets.

concentration and estimated flow of soluble non ammonia nitrogen entering the omasum of dairy cows as influenced by different Protein Supplements
Agricultural and Food Science, 2002Co-Authors: Chang Weon Choi, Aila Vanhatalo, Pekka HuhtanenAbstract:Four ruminally fistulated Finnish Ayrshire cows were used to study the effects of different Protein Supplements on concentration and flow of soluble non-ammonia N (SNAN) into the omasum. The treatments in a 4 · 4 Latin square design were a basal diet of grass silage and barley and the basal diet supplemented with fishmeal, soybean meal and maize gluten meal. Protein Supplements significantly increased concentrations of peptide N (P = 0.009) and total SNAN (P = 0.03) fractions in omasal digesta. Peptide constituted the largest proportion of SNAN flow into the omasum indicating that hydrolysis of peptides to amino acids is the most limiting step in rumen proteolysis. The microbial contribution to SNAN was on an average 0.64 indicating that a large proportion of SNAN flow leaving the rumen was of microbial origin. The estimated SNAN flow per kg dry matter intake from the basal diet and Protein supplemented diets indicated that approximately 49, 22 and 37 g kg -1 of fish

effects of different Protein Supplements on omasal nutrient flow and microbial Protein synthesis in lactating dairy cows
Journal of Dairy Science, 2007Co-Authors: A F Brito, G A Broderick, S M ReynalAbstract:Abstract Eight ruminally cannulated Holstein cows that were part of a larger lactation trial were used in 2 replicated 4×4 Latin squares to quantify effects of supplementing Protein as urea, solvent soybean meal (SSBM), cottonseed meal (CSM), or canola meal (CM) on omasal nutrient flows and microbial Protein synthesis. All diets contained (% of dry matter) 21% alfalfa silage and 35% corn silage plus 1) 2% urea plus 41% high-moisture shelled corn (HMSC), 2) 12% SSBM plus 31% HMSC, 3) 14% CSM plus 29% HMSC, or 4) 16% CM plus 27% HMSC. Crude Protein was equal across diets, averaging 16.6%. The CSM diet supplied the least rumen-degraded Protein and the most rumen-undegraded Protein. Microbial nonammonia N flow was similar among the true Protein Supplements but was 14% lower in cows fed urea. In vivo ruminal passage rate, degradation rate, and estimated escape for the 3 true Proteins were, respectively, 0.044/h, 0.105/h, and 29% for SSBM; 0.051/h, 0.050/h, and 51% for CSM; and 0.039/h, 0.081/h, and 34% for CM. This indicated that CSM Protein was less degraded because of both a faster passage rate and slower degradation rate. Omasal flow of individual AA, branched-chain AA, essential AA, nonessential AA, and total AA all were lower in cows fed urea compared with one of the true Protein Supplements. Among the 3 diets supplemented with true Protein, omasal flow of Arg was greatest on CSM, and omasal flow of His was greatest on CSM, intermediate on CM, and lowest on SSBM. Lower flows of AA and microbial nonammonia N explained lower yields of milk yield and milk components observed on the urea diet in the companion lactation trial. These results clearly showed that supplementation with true Protein was necessary to obtain sufficient microbial Protein and rumen-undegraded Protein to meet the metabolizable AA requirements of high-producing dairy cows.

effects of different Protein Supplements on milk production and nutrient utilization in lactating dairy cows
Journal of Dairy Science, 2007Co-Authors: A F Brito, G A BroderickAbstract:Sixteen (8 ruminally cannulated) multiparous and 8 primiparous lactating Holstein cows were used in 6 replicated 4 x 4 Latin squares to test the effects of feeding supplemental Protein as urea, solvent soybean meal (SSBM), cottonseed meal (CSM), or canola meal (CM) on milk production, nutrient utilization, and ruminal metabolism. All diets contained (% of DM) 21% alfalfa silage and 35% corn silage plus 1) 2% urea plus 41% high-moisture shelled corn (HMSC), 2) 12% SSBM plus 31% HMSC, 3) 14% CSM plus 29% HMSC, or 4) 16% CM plus 27% HMSC. Crude Protein was equal across diets, averaging 16.6%. Intake and production were substantially reduced, and milk urea, blood urea, and ruminal ammonia were increased on urea vs. the diets supplemented with true Protein. Although intake was lower in cows fed SSBM compared with CM, no differences were observed for milk yield among SSBM, CSM, and CM. Yields of fat and Protein both were lower on CSM than on CM, whereas SSBM was intermediate. Milk urea and milk Protein contents also decreased when CSM replaced SSBM or CM. Diet did not affect ruminal volatile fatty acids except that isobutyrate concentration was lowest on urea, intermediate on CSM, and greatest on SSBM and CM. Urinary excretion of urea N and total N was greatest on urea, intermediate on SSBM and CM, and lowest on CSM. Apparent N efficiency (milk N/N intake) was lower on the CSM diet than on the SSBM diet. Overall, production and N utilization were compromised when the diets of high-yielding dairy cows were supplemented with urea rather than true Protein and the value of the true Proteins.
