The data on feeding dairy cows of an energy protein concentrate (EPC) are presented. EPC consists of grain of narrow-leaved lupine, flax, triticale, subjected to heat treatment on a press extruder. The effect of EPC on the change in milk production of cows was determined. The inclusion of extruded concentrate based on lupine grains in the diets of cows made it possible to obtain an increase in milk. Concentrate based on lupine, flax, triticale is equal in biological value to full-fat soy, and at a much lower cost.

Ten multiparous Holstein cows were used in a 105-day continuous feeding trial to compare soybean meal (SBM) and alfalfa protein concentrate (APC) as supplemental protein sources for high-producing dairy cows. Dairy cows with an average milk production of 35.2 kg/day were paired and randomly assigned to one of the treatments. A double reversal design was employed With 35 days per period. The comparison between treatments was made during the last 21 days of each period. Experimental diets, containing 60% corn silage and 10% alfalfa hay, were formulated to be isonitrogenous and isoenergetic (crude protein. 15.6%; net energy tor lactation, 1.60 Mcal/kg DM). Fifty percent of dietary nitrogen was provided by test proteins. Animals were fed four times daily. Chromie oxide boluses, 50 g/day were used to estimate digestion coefficients. Ruminal protein degradability in viva (%) and in situ(%)were 56.8, 68.3 and 47.3. 35.3 for SBM and APC, respectively. Dry matter intake (kg/day) was 19.1 and 18.6 for cows fed SBM and APC. respectively. Rummal parameters cows fed SBM vs APC were, pH. 6.6 vs 6.7, ammonia nitrogen(mg/dI) 10.8 vs 6.2(p less than 0.01); total volatile fatty acids (mM), 86.3 VS 84.6(P LESS THAN 0.05), acetate (%) , 50.8 vs 64.9 (p less than 0.01); propionate dry matter , 65.3 vs 61.8; crude protein . 67.6 vs 61.1 (P less than 0.05 ) neutral detergent fiber , 51.1 vs 52.5 ; acid detergent fiber, 47.7 vs 49.0 . A slightly higher (P more than 0.05 ) amount of milk was produced by cows fed APC(28.6+_ 3.5 vs 28.2+- 3.8 kg/day). Each additional gramof undergradable intake protein provided by APC continued to a 5- gram increase in 4% fat-corrected milk production.

Feed Costs

Studies reported by Mayne (1990) and Slater (1989) have shown that the yield of milk achieved by feeding a low level of a high protein concentrate with a good quality silage fed to appetite was comparable to that obtained by feeding higher levels of a conventional concentrate containing a normal level of protein (160-180g CP/kg). These results would indicate that there is considerable scope to reduce concentrate feeding levels and reduce feed costs when good quality grass silage is available. However, in previous studies at this centre (Murphy, 1987) very low levels (2.4 kg/d) of high protein concentrates (400-450 g CP/kg) fed with a good quality grass silage reduced milk production compared with a moderate level (6 kg/d) of a normal protein concentrate (160-180 g CP/kg).The present study was carried out to clarify the position and to establish the benefit of including a source of undegradable protein, e.g. maize distillers grains or fishmcal in place of soyabcanmeal in the prolein concentrate.

Tolkamp et al. (1996) reported that dairy cows were able to choose between complete foods with different MP:ME ratios, and it was concluded that the selection the cows made was not random. Diet selection may remove nutritional constraints on milk production if the cow can choose the appropriate protein level to attain the milk yield determined by her genotype. At a specific DUP content the diet of an individual cow will be correctly balanced. When the cow is offered two foods, one in excess of predicted requirements for DUP, the other deficient in DUP for the predicted level of production, then the cow has the opportunity to select a diet which exactly meets her requirements for DUP. Most diet selection experiments have been completed under conditions of little or no competition; the aim of the experiment was to study the effects of offering lactating cows a choice between two protein concentrates under semi-commercial conditions.

In a four year grazing trial with dairy cows the application of 5000 kg lime/ ha (applied in two applications of 2500 kg/ha in winter of the first two years) significantly increased annual pasture production in two of the four years and dairy production in one year. In three of the four years lime significantly increased pasture growth over summer/autumn with concurrent increases in milk production. In the last year of the trial lime had little effect on pasture growth but a relatively large increase in milkfat production resulted. A higher incidence of grass staggers was recorded on the limed farmlets in spring for each of the four years. In the second spring immediately following the second application of lime significant depressions in both pasture and plasma magnesium levels were recorded. By the third spring differences in plasma magnesium levels were negligible but small depressions in herbage magnesium resulting from lime continued to the end of the trial. Lime significantly raised soil pH, Ca and Mg levels but had no effect on either soil K or P. As pH levels of the unlimed paddocks were low (5.2-5.4) in each autumn and soil moisture levels were increased by liming, these factors may suggest possible causes for the seasonality of the pasture response to lime

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.
