The paper presents testing results of feeding dry cows and horses with cryo-feed, preserved by using natural techniques, at winter grazing (tebenevka). Research into digestibility of nutrition substances of cow ration was carried out on 30 cows of Sirrrmental breed divided into three groups (control and two experimental ones, whose ration included 4 and 1.5 kg of cryo-feed respectively). The introduction of cryo-feed in the ration of cows increased the level of metabolizable energy and had a positive impact on the efficiency of energy metabolism. Cows of the 1 st experimental group, where cryo-feed accounted for 12% of the nutrition ration, showed 5.8% higher protein digestibility than the control group. Feeding cows with cryo-feed in the dry period contributed to the maintenance of reproductive qualities. The percentage of fertilization of cows was 90-100%. It was established that feeding horses on cryo-feed significantly increased their nutritional level at tebenevka in the winter time and fully met the need of animals in feeding elements. This marked a high horse feeding capacity per 1 ha of cryo-feed, which amounted to 129-142 horse days. The advantage in organic matter digestibility at tebenevka on cryo-feed accounted for 11.9%, dry matter - 10.48%, crude protein - 18.3%, crude fiber- 21.9%, crude fat - 13.3%, and nitrogen-free extractive substances - 11.7%. The energy supply of a horse organism per 100 kg of live weight was 32.6 MJ, which exceeded the norm by 14.5%. Better digestibility of nutrients of winter-green mass of oats compared to the grass stand was due to the high content of carotene and provitamin Е in plants preserved on the root by natural cold. During the study it was established that the actual foal crop increased by 12-14% at tebenevka with horses on cryo-feed compared to traditional technology.

The aim of the present study was to evaluate the effect of replacing concentrate feed (CFM) mixture with different levels of treated lemon pulp (TLP) on milk production and composition, nutrients digestibility, and blood parameters of Zaribi goats. A total of 24 Zaribi female goats at the end of the pregnant period were divided into three groups of eight according to live weight. Concentrate feed mixture and clover hay at a rate of 50:50 were offered twice a day. Treatedlemon pulp replaced CFM at rates 0%, 25%, and 50 % in diets of R1, R2, and R3 treatment groups, respectively. The feeding trial lasted 90 days. Dry matter digestibility and Nitrogen free extract digestibility were significantly raised by the increased level of TLP in groups R2 (72.37% and 70.36%) and R3 (72.28% and 70.30%), compared to (70.99% and 68.51%) in R1, respectively. The same trend was observed for organic matter digestibility (OMD), crude protein digestibility (CPD), crude fiber digestibility (CFD), and ether extract digestibility (EED) with R3, compared with either R1 or R2. However, there were insignificant differences between R1 and R2 in terms of OMD, CPD, and EED but CFD was significantly higher in R2, compared to R1. There was a significant increase in the milk yield by the increased level of TLP in the diet and for R2 (1448.4g/h/d) and R3(1558.7g/h/d), while it was reported as 1377.6 g/h/d in the control group. Feeding dams on the R3 diet had a significant effect on improving total antioxidant capacity by 63.5%, compared with control. The results of the present study indicated that the replacement of CFM by TLP decreased the costs of feed and increase milk production for the replacement level by 50% (R3). Moreover, no adverse effects were noticed on nutrients digestibility and blood parameters of the investigated samples.

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.

SummaryTwo experiments were conducted with milking cows on continuously stocked perennial ryegrass pastures. In each a control group, T0, received 1 kg/day of a concentrate supplement and treatment groups T1 and T2 received 4 kg (Expt 1) or 5 kg/day (Expt 2) of a low quality T1 or a high quality T2 concentrate. In Expt 1 treatments were applied continuously for 14 weeks to a total of 30 cows. In Expt 2 a Latin square design for 9 weeks was conducted with 18 cows. The stocking rate of the pasture declined from 9·6 to 5·1 cows per ha (mean 6·7 cows/ha) from May to August (Expt 1) and was maintained at 3 cows/ha in August-October (Expt 2).Supplements increased total intakes by 0·92 and 0·77 kg organic matter (OM)/kg OM supplied in the concentrates respectively for Expts 1 and 2. Milk yields increased by 0·6 and 0·5 kg/kg concentrate supplied and supplemented cows showed small increases in live weight. Differences in lactation milk yield just approached significance. Grazing times were only slightly reduced by supplements and bite sizes were lower than normal. There was no important difference in animal performance between the two concentrates. The total output from the pasture was 19·6t milk and 115 GJ of utilized metabolizable energy per hectare.Reasons for the high supplementary effect of the concentrates and its implications for stocking rates are discussed.

This research was carried out to determine the effect of Jerusalem artichoke (JA) with or without 5, 10% vetch (V) supplementation on performance, egg quality characteristics and egg cholesterol content. In the study, seventy-five 25 weeks-old commercial white laying hens were randomly divided into one control and 4 treatment groups each containing 15 hens. Control group was fed basal diet without JA or V. Treatment group 1, 2, 3 and 4 were fed diets containing 5% V, 5% JA, 5% JA + 5% V and 10% JA + 10% V, respectively. The feeding period lasted 16 weeks. In the study, it was determined that dried-ground JA contained dry matter, crude protein, ether extract, crude fibre, crude ash, inulin and metabolizable energy (ME) at the level of 93.30, 10.02, 0.36, 5.64, 9.05, 15.80% and 3 060 kcal/kg, respectively. At the end of the study, live weight was lower by 4.36&ndash;10.09% in the treatment group 10% JA + 10% V compared with the other groups, but feed efficiency was improved in this group. There were statistically significant differences between the groups in egg quality characteristics (P &lt; 0.05, P &lt; 0.001). Egg production was not affected by supplementation of 5, 10% JA with or without 5, 10% V supplementation. Egg yolk cholesterol and total cholesterol content were not different in the groups (P &gt; 0.05). As a result, the addition of JA with or without V has no adverse effect on performance and egg quality in hens. &nbsp;

ABSTRACTTwo groups of 14 intact male weanling beef breed calves were each fed 1·45 kg oat hay daily and concentrates ad libitum, in a 158-day feeding trial. Group ‘a’ received 35 p.p.m. monensin in the concentrate. Group ‘b’ served as a control.Average daily gain was 1·28 and 1·27 kg, dressing percentage was 58·1 and 58·0, daily intake of concentrate was 8·10 and 8·79 kg and conversion ratio of metabolizable energy into live weight was 74·53 and 81·30 MJ/kg for the monensin and the control group respectively. The percentage of acetic acid in rumen liquor was reduced and that of propionic acid increased very markedly. As a result the acetic acid: propionic acid ratio was reduced from 3·2 in the control group to 1·8 in the monensin group. No peculiarity in the response of intact male cattle to monensin was observed.

The article analyses the issues of balanced feeding of broiler chickens and their balanced diet. The results of studies aimed to determine the effect of mixed feeds on the productivity of Arbor Acres cross broiler chickens and the economic efficiency of poultry meat production companies are presented. It was found that broilers from the experimental group, who were fed with improved compound feed with additional sources of proteins and carbohydrates and feed additives exceeded broilers from the control group by their live weight at all ages. At the slaughter age, the average weight was more than 39.2%. The experimental group consumed 10-15% less feed whose conversion was 2.4 and 1.9 kg in favour of the group feeding with the new compound feed. The new compound feed had a positive effect on the viability of broilers: there were no deaths during the period under study. According to the control slaughter results, it was found that the pre-slaughter live weight was higher by 35% in the experimental group. The weight of edible parts increased by 6%. The improved compound feed can be used both in industrial conditions and by poultry farms.

In Oman, efforts are underway to find alternative sources of fwd to support domestic livestock. The date industry thrives in Oman and one of its by-products is date fiber, a by-product of date syrup production. Although the product contains some free sugars, an evaluation of its potential in broiler diets has never been undertaken. Therefore, we conducted an experiment to investigate the value of date fiber in broiler chick diets. The experimental diets consisted of four graded levels of date fiber: 0, 15, 30 and 45 % in a broiler-starter ration replacing corn as an energy source. The diets were isonitrogenous. There were five replicates for each of the four diets and each replicate contained six broiler chicks. As date fiber percent increased in the dietary treatment, there were linear reductions in body weight gain, calculated apparent metabolizable energy (AMEn) content, and apparent protein digestibility (P < 0.05). Poor feed utilization (i .e., reduced feed efficiency) was observed in birds fed date fiber diets compared to the control group (P < 0.05). The poor performance of birds fed date fiber may be attributed to protein and energy limitations. We conclude that date fiber has no value in growing broiler diets. However, it may have utility in diets where a stable body weight is desirable.

The possibilities of increasing the productivity of animals and poultry when using an additive containing selenium, rapeseed cake and a complex mineral additive have been studied. Adding to the feed of selenium-containing drug “Carasel” enhanced the digestibility of nutrients, increase of erythrocytes, hemoglobin in the blood, yield of certifi ed goslings, and profi tability. The digestibility of dry and organic matter has increased by 0,46–1,14 %, protein – up to 5,15 %. Depending on the dose of the additive the digestibility of raw fi ber, raw fat, and nitrogen-free extractive substances were higher. Certifi ed goslings have been received 19–22 % more. The inclusion of rapeseed cake of Siberian selection in compound feed when rearing goslings had a positive eff ect on the growth of live weight, the output of the gutted carcass. Goslings of the 1st experimental group exceeded the live weight of goslings of the control group by 3,4 %, and the 2nd experimental group by 6,1 %. The weight of the semi-gutted carcass was higher in the experimental groups receiving rapeseed presscake and rapeseed presscake in combination with rapeseed oil, and exceeded the weight of carcasses of the control group by 298,22 and 388,48 g (P ≤ 0,001), respectively. The weight of gutted carcasses was also significantly higher in the experimental groups. A complex mineral additive in the ration of steers of Hereford breed contributed to the increase in their live weight at the age of 15 months, slaughter yield, profitability of production and improvement of beef quality. The pre-slaughter weight of steers in the experimental group was 465,67 kg and was by 19,0 kg or 4,25 % more than that of steers in the control group (P ≤ 0,001). Studies have shown that the carcass weight was higher in the experimental group than in the control group by 12,09 kg or 4,39 % (P ≤ 0,001). The slaughter yield was 1,08 % higher. Economic evaluation of the use of feed additive in the experiment in the steers of Hereford breed has shown that the use of the developed mineral feed additives contributed to the increase in live weight of steers and the profi tability of production. The level of profitability in the group of steers experimental group receiving comprehensive mineral additive amounted to 13,80 % in comparison with the control group where it was equal to 9,40 %.

Nutrient Digestion

The domestic donkey is a unique equid species with specific nutritional requirements; however, limited feeding studies have been addressed so far to understand nutrient digestion and metabolism in donkeys. In the present study, six adult female Xinjiang donkeys (180 ± 10 kg live weight) were applied in a 3 × 3 Latin square design to investigate the effect of the forage/concentrate ratio (F/C) in three experimental diets on N and energy balance within 12 weeks. Rice straw and alfalfa hay were chosen as forage ingredients, and the diets included the following: (1) a high-fiber (HF) ration (F/C = 80:20), (2) a medium-fiber (MF) ration (F/C = 55:45), and (3) a low-fiber (LF) ration (35:45). After the fixed amount of diets were daily allowed to the animals, total feces and urine were collected to determine total tract digestibility, N and energy balance. As a result, dry matter intake did not differ among the three diet groups. Decreasing the dietary F/C significantly promoted protein digestibility and decreased fiber digestibility. The N and energy balance analysis showed that increasing the F/C remarkably (p < 0.01) decreased N retention through the increase in N excretion in urine, and the highest N loss relative to N intake was observed in MF. Meanwhile, decreasing the F/C linearly increased the conversion efficiency of digestible energy to metabolizable energy. Taken together, the results obtained in the present study implicated that the dietary forage level should not be less than 55% to maintain greater N and energy utilization in feeding practice, otherwise, a donkey’s N utilization might be highly discounted.

In a scientific and economic experiment lasting 90 days on 4 groups of black-and-white calves, formed by the method of analogs, the effect of a complex mineral-vitamin feed supplement (CMVFS ) on the nutrient digestibility of feed in the Republic of Bashkortostan was studied. Animals of the control group received the basic diet (BD) and mineral feeds (chalk, salt, premix); I, II and III experimental groups — BD + CMVFS according to recipe No. 1, No. 2 and No. 3 respectively. A distinctive feature of the recipes is the ratio of natural zeolite and sapropel in 1 kg of the supplement. It was found that the content of calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc and cobalt in the green mass, as well as in the feed harvested from it, does not meet the needs of young animals. Significantly high digestibility of dry and organic matter relative to the control was observed in animals of group III by 3.84% (R<0.05) and 2.78% (R<0.05); crude protein — by 3.21 and 3.96% — in young animals of groups II and III (R<0.05); crude fat — by 2.83% (R<0.05) in group I, by 4.01% (R<0.05) in group II and by 5.05% (P<0.01) in group III; nitrogen-free extractive substances — by 3.24% (R<0.05) in II and by 3.67% (R<0.05) in III experimental groups. The balance of nitrogen and minerals in all experimental groups was positive. The digested and deposited nitrogen in the body corresponds to the obtained average daily live weight gain of calves. In order to balance the diets of calves in terms of macro- and microelements, we recommend vitamins to introduce CMVFS according to the recipe No. 3 into the mixture of grains at the rate of 35 g per 1 head per day.
