Feeding Value

Twenty-four dairy cows were used in an experiment in which 1) soybean meal, 2) rapeseed meal and 3) rapeseed meal plus urea were compared for feeding value, when given as protein sources in grass silage- and hay-based feeding. About 25 % of the digestible crude protein required for milk production was replaced with these protein sources. The rapeseed meal was mainly of the Span variety. The rapeseed meal composed 13% of a concentrate mixture also containing barley, oats and molassed beet pulp. The daily consumption of rapeseed meal was up to 1.2kg/cow, the average being 1.0kg/cow. As a protein source the rapeseed meal was almost equivalent to the soybean meal. There were no significant differences between the groups in the intake or utilization of the feeds, milk production or milk composition, or liveweight changes. The replacement of silage protein with rapeseed meal or with soybean meal improved the utilization of the protein of the whole ration for milk production.

High Production

Twenty-four dairy cows with high milk yields were used in an experiment in which peas and soybean meal were compared for feeding value, when given as protein sources in grass silage and hay based feeding. In their barley and outs based concentrate mixture three different groups recevied: 1) soybean meal 14 %, 2) soybean meal 7.5 %plus ground peas 15 % or 3) ground peas 35%. The peas were almost equivalent as a protein source to the soybean meal. There were no significant differences between the soybean and pea groups in the intake and utilization of feeds, milk production and milk composition or liveweight changes of the animals. Thus, in silage and hay based feeding the proportion of peas in the concentrate mixture can be at least 35 % and the daily pea ration can amount to 3—4kg without any harmful effects on milk production.

The effect of rapeseed meal (RSM) supplementation on the performance of dairy cows on direct cut grass silage based diets was studied in five feeding trials. The proportion of RSM varied from 0% to 33% in the concentrate mixture (the grain was an oat-barley mixture of 1:1). In one experiment the treatments were RSM and soybean meal (SBM), while in another experiment forage was either grass silage or bam dried hay cut at the same maturity. In addition, this was compared to the data of other trials in Finland during the last ten years, in which RSM supplementation had been used. Using this data the response in terms of milk yield to RSM supplementation was estimated. The utilization of protein in milk production was estimated by the Nordic AAT-PBV protein evaluation system. During the experiments (1983-1990) the varieties of turnip rape were changed from high glucosinolate, containing single-zero, to low glucosinolate containing doublezero varieties, while the glucosinolate content was reduced from 40-50 μmoles to 14 μmoles per g of defatted meal. Heat-moisture treatment (™Öpex) further reduced the glucosinolate content by half. By replacing grain with RSM in the concentratemixture with ad libitum silage feeding, the silage intake increased by 0.43 kg per kg increase in RSM on the basis of dry matter (DM) (non significant). The response in increased milk production was 0.77 kg in milk or 0.70 kg in energy corrected milk (ECM) yield (P

Three experiments were conducted with dairy cows to determine the effects of rapeseed meal and/or urea upon ad libitum consumption of grain rations. In corn, corn–barley and barley-oat basal rations, replacement of soybean meal (10%) by rapeseed meal (12–13%) resulted in a decrease in grain intake. Substitution of 1.4% or 1.6% urea (22% or 19% of the total crude protein intake) for soybean meal also resulted in decreased ad libitum grain consumption. A combination of rapeseed meal (6%) and urea (08%) was comparable to 12% rapeseed meal in effect upon consumption but less marked than 1.6% urea. No rations containing rapeseed meal had significant effects upon milk composition or production. In one experiment, a significant decrease in production occurred through including 1.6% urea in the grain ration.

AbstractFour dietary treatments were based on a flat-rate (5 kg/day) of concentrates with ad libitum grass silage. The concentrates were iso-energetic and iso-nitrogenous, based on either barley or unmolassed sugar-beet pulp and either extracted rapeseed meal (RSM) or a 1: 3 mixture of fish and soya-bean meals (F/S). These diets were offered to 61 multiparous Holstein-Friesian cows in a continuous design experiment from lactation weeks 4 to 22. Milk yields tended to he higher with RSM (25·1 v. 23·9 kg/day; s.e.d. = 0·64; P < 0·1), whilst milk fat (38·1 v. 40·0 g/kg; s.e.d. = 0·81) and milk protein (30·4 v. 31·3 g/kg; s.e.d. = 0·41) concentrations were significantly (P < 0·05) lower. There were no significant effects of treatments on the efficiency of conversion of food-nitrogen (N) to milk-N or on N-retention. A lower organic matter apparent digestibility (g/g) was found for RSM-based diets (0·738 v. 0·763; s.e.d. = 0·0096; P < 0·05). The diets were also offered to four fistulated dairy cows in a Latin-square-design experiment. Concentrate energy source had significant effects on rumen pH (P < 0·05) and ammonia-N concentration (P < 0·01), whilst protein sources had no effect; values were always in the optimal range (pH > 6 and ammonia-N > 50 mg/l). There was a significant interaction effect (P < 0·05) such that the N-degradability of the whole diet, estimated in vivo, was unaffected by energy source for RSM-based diets but highly dependent on energy source for FIS diets. Microbial protein yield was reduced on the RSM-based diets (179 v. 220 g/day; s.e.d. = 9·6; P < 0·001).

Higher dry matter intakes (DMI) have been reported in dairy cows fed maize silage than in dairy cows fed grass silage. The objective of this experiment was to investigate this phenomenon by the measurement of digestibility and the determination of rumen outflow rates for both forages. The response in milk production of late lactation dairy cows to grass or maize silage was also measured.Fourteen late lactation multiparous dairy cows (n = 7) were fed diets containing either grass silage (GS) (DM: 197g/kg; pH: 4.05; NDF: 642g/kg DM) or high starch maize silage (MS) (DM: 339g/kg; pH: 3.94; starch: 360g/kg DM; NDF: 442g/kg DM) ad-libitum plus 4kgs/hd/day of a dairy concentrate (233g CP/kg DM). Urea (460g N/kg DM) was used as a source of degradable protein (10g/kg DM) for the MS diet which also included straw (40g/kg DM). Dietary NDF equalled 542 and 423g/kg DM for the GS and MS diet.
