The purpose of the research is increase the concentration of energy in the dry matter of cows diets with a productivity of 7-8 thousand kg of milk per year in the first third of lactation with the use of dry palm fats prepared by various technologies. In the experiment carried out on three groups of Holstein dams cows of Black-Motley Breed with the productivity of about 7.500 kg of milk per year for 9 cows each, it was found that the inclusion of dry palm fat (II experimental group – 300 g of fractionated fat with a predominance of saturated fatty acids and III experimental group – 368 g of fat in the form of calcium salt) in the composition of the rations of cows experimental groups with the aim of balancing the metabolizable energy content to the level of crude fat in an amount of 5% of the dry matter, has no adverse effect on dry matter intake of the ration, the digestibility of nutrients of feed and the use of nitrogen, calcium and phosphorus. The result of balancing the ration of cows of the experimental groups the concentration of metabolizable energy in dry matter from 10.3 MJ/kg in the control to 10.7 MJ/kg in the experimental groups, the increase in cow milk yield, standard (4%) fat content for 100 days of lactation was 8.8% (P≤0.05) and 7.6% increase in the yield of milk fat and protein. Feed costs per 1 kg of milk of cows of experimental groups, expressed in exchange energy, were below control by 3.7 and 2.6%, respectively. According to the results of biochemical blood tests, against the background of the tendency of increasing the intensity of nitrogenic and lipid metabolism, a significant decrease in the concentration of ketone bodies in the blood of cows of experimental groups was found. Feeding by dry palm fats in tested quantities does not reduce the reproductive function of cows and is economically justified.

Processing technologies using non-reactive influences appear to be the most profitable in terms of safety and ecological compatibility of end products including fodder for the agro-industrial complex. The usage of various physical influences allows significantly speeding up and facilitating technological processes including those achieving results that are not possible with other technologies. Based on the study of morphological and biochemical indicators of blood, it can be stated that the introduction of cavitationally processed sunflower sludge into the diet of birds together with zeolite powder leads to improving general blood indicators. All biochemical and morphological indicators were within the physiological norm. The results indicate that the cavitational processing of sunflower sludge with zeolite particles comprising feed mixes with an additional increase in the level of metabolizable energy leads to an increase in the content of macro- and microelements against the background of a significant reduction of elements-antagonists. The greatest changes were observed in the second experimental group, (a diet with a metabolizable energy content of 14.9 MJ/kg of dry matter (DM), which consists of 6 % of cavitationally processed sunflower sludge in the presence of zeolite in the amount of 4 %).

Nutritional Benefits

Recently, camel milk (CM) has been considered as a health-promoting icon due to its medicinal and nutritional benefits. CM fat globule membrane has numerous health-promoting properties, such as anti-adhesion and anti-bacterial properties, which are suitable for people who are allergic to cow’s milk. CM contains milk fat globules with a small size, which accounts for their rapid digestion. Moreover, it also comprises lower amounts of cholesterol and saturated fatty acids concurrent with higher levels of essential fatty acids than cow milk, with an improved lipid profile manifested by reducing cholesterol levels in the blood. In addition, it is rich in phospholipids, especially plasmalogens and sphingomyelin, suggesting that CM fat may meet the daily nutritional requirements of adults and infants. Thus, CM and its dairy products have become more attractive for consumers. In view of this, we performed a comprehensive review of CM fat’s composition and nutritional properties. The overall goal is to increase knowledge related to CM fat characteristics and modify its unfavorable perception. Future studies are expected to be directed toward a better understanding of CM fat, which appears to be promising in the design and formulation of new products with significant health-promoting benefits.

This paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

Friesian Cows

Four groups of seven Friesian cows were offered 70% of their calculated metabolizable energy requirements as pasture hay and either 2.4, 4.8 or 7.2 kg/d of dry matter (DM) as wet brewers' grains or 3.9 kg DM/d as rolled barley. A further group of cows received no supplement. The quantities of brewers' grains offered were calculated from in vitro digestible DM content to provide lo%, 20% and 30%, respectively, of metabolizable energy requirements and the rolled barley 30% of metabolizable energy requirements. The cows consumed a mean of 2.2,4.3 and 6.1 kg DM/d, respectively, as brewers' grains and 3.9 kg DM/d as rolled barley. The daily yields of milk (litres), protein (kg) and solids not fat (kg), respectively, were greater (P < 0.05) for the cows offered brewers' grains at 4.8 kg DM/d (1 5.6,0.49, 1.36) and 7.2 kg DM/d (16.4, 0.54, 1.45) than for the cows offered rolled barley (13.3, 0.45, 1.21). Daily yields of milk fat from the cows offered either 4.8 or 7.2 kg DM/d of brewers' grains or rolled barley did not differ significantly. There were no significant differences between treatments in liveweight change. It was concluded that wet brewers' grains and rolled barley offered as supplements to dairy cows fed hay have similar nutritive values for milk production. It was calculated that for milk fat production the break even landed price ratio of brewers' grains to barley is 1:1.26.

This study planned to determine the differences among nutrient composition, in vitro digestibility, energy content, digestible dry matter and organic matter yields of barley forage harvested at three different stages of maturity. Each vegetation period (heading stage, seed formation stage and mature stage) was randomly assigned to 5 replication from 1 square meter area and fifteen samples were harvested in total. DM, ADF (p<0.001), and NDF (p<0.05) contents were different in each stages of barley forage. In vitro dry matter (IVDMD), organic matter digestibility (IVOMD), metabolizable energy (ME), and net energy for lactation (NEL) values of samples were determined to be lower than the other two stages at the mature stage (p<0.05). Yield parameters of barley were significantly affected by vegetation period (p<0.001). It can be concluded that all three vegetation period had significantly higher digestibility. Digestible DM, OM and energy yields were higher when harvested at the mature stage of vegetation.

SUMMARYThe net energy values for growth and fattening of two artificially dried tropical grasses-, pangola (Digitaria decumbens) and setaria (S. sphacelata var. sericea cv. Nandi), of similar estimated metabolizable energy content (8·07 and 7·96 MJ/kg D.M.) were determined with cattle using a slaughter technique. Growing cattle with a mean initial weight of 175 kg were given equal quantities of dry matter of the two grasses at each of three planes of nutrition above maintenance for a period of 152 days.The initial energy, fat and protein content of the total body of the 24 test animals was estimated from regressions relating fasted live weight to theśe components, derived from 12 similar cattle slaughtered at the beginning of the feeding period. The final energy, fat and protein content of the test animals was determined directly by chemical analysis. The metabolizable energy (ME) content of the grasses was estimated from the level of digestible energy (DE) determined with eight cattle, assuming that ME = 0·815 DE.The cattle fed pangola gained more live weight, empty-body weight, fat, protein and energy than animals fed similar quantities of setaria. The net energy value for growth and fattening (NEf) was determined using regressions relating energy retention to the quantity of dry matter eaten. NEf in MJ/kg dry matter was 2·27 for pangola and 1·31 for setaria.Efficiency of utilization of ME for growth and fattening (kf) was.27·7% for pangola and 16·9% for setaria. These values for tropical grasses are lower than any values reported for temperate pasture species. Thus the lower efficiency of utilization of ME may cause the lower production of cattle which graze tropical grasses.It was concluded that as the kf values of different tropical grasses are not constant, kf values should be measured on a wider range of tropical grasses so that this factor can be taken into account when evaluating grasses in animal production systems.

The influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.

An important factor in increasing the productivity of dairy cattle is to ensure the full value of diets by improving the quality of feeds and enriching its with a complex of additives from alternative sources, in particular from the richest forest resources. Scientific-economically experience by studying the effect of feeding coniferous flour on milk productivity and metabolic parameters of cows and determining its optimal dosage was carried out in the conditions of LLC Plemzavod Tayozhny Sukhobuzimsky district of the Krasnoyarsk territory. Three groups of milking cows (control and two experimental) of the Black-Motley breed of the second calving, 5 heads in each group were formed for the experiment on the principle of analogues. The duration of the experiment was 100 days. According to the scheme of studies, the control group received the main diet, the 1st experimental group in addition to the main diet received coniferous flour at a dosage of 50 g/head/day, the 2nd experimental group coniferous flour at a dosage of 100 g/head/day. Research and data processing were carried out according to generally accepted methods. As a result of researches positive influence of coniferous flour on milk productivity and technological properties of cow milk was established. The analysis of the obtained data allowed to determine the most effective dosage of coniferous flour for the diet of cows 50 g/head/day, which contributed to an increase in milk yield for 100 days of lactation by 15.6%, the milk fat amount by 29.8%, the milk protein amount by 17.1%, milk of basic fat content by 29.4%, improvement technological properties of milk.
