The article presents the results of the effect of partial replacement of mixed feeds with organic concentrate based on dry bird droppings (DBD) on the preservation of quail, quantitative and qualitative rates of egg productivity. For the laboratory experiment, 5 experimental groups of Manchurian quail were formed by the analogous pair comparison method. The quail of the control group consumed all-in-one feed (AF), for the quail of the experimental groups (I, II, III, and IV) part of the AF – 10, 15, 20 and 25 % by weight – was replaced with organic concentrate. Results of studies reveal that the introduction of 10 % of organic concentrate into the AF contributed to improved feed intake and livestock safety, increased egg productivity and reduced feed consumption per unit of output. With respect to the indicators of biological usefulness, toxicological and sanitary-epidemiological safety, quail eggs treated with the organic concentrate met the requirements of GOST and TR TS 021/2011 “On food safety”.

Poultry Farming

One of the main factors that ensure the growth of profitability of poultry farming is the partial replacement of grain crops with non-traditional feed with low cost, which, for example, can be considered processed dry bird droppings (SPP). The aim of the research was to study the effect of organic concentrate based on SPP on the morphological parameters of quail eggs. For the study, 5 experimental groups of quails were selected using the method of analog pairs. The birds of the control group received factory-made feed DC-52-100 %, the quails of the experimental groups (I, II, III and IV) were replaced by 10, 15, 20 and 25% by weight, respectively, with an organic protein concentrate based on SPP. In studies, it was found that the introduction of an organic concentrate based on SPP in the amount of 10, 15, 20, 25 % instead of a similar amount of mixed feed contributed to an increase in the relative weight of the yolk by 1,55; 4,51 (P≤ 0.05); 0,64 and 1,87 %, a decrease in the protein/yolk ratio by 2,07; 6,74 (P≤ 0.05); 0,52 and 3,13%, respectively, relative to similar indicators of eggs of the control group. The addition of organic concentrate based on SPP to the composition of mixed feeds contributed to the improvement of the morphological parameters of food eggs and the quality of the shell. The weight of eggs practically did not change when replacing 10,0% of the complete feed with a similar amount of organic concentrate, while the picture was ambiguous when increasing the dose of the test feed.

In mammals, time-restricted feeding (TRF) with no caloric restriction provides health benefits and extends longevity, usually with a minor (∼3%) or no reduction in total food consumption. In the current study, a TRF regimen of 6 h free access to food (08:00–14:00 h) was applied to Leghorn chickens from 25 to 86 weeks of age; control birds ate freely during the light hours (06:00–20:00 h). Unexpectedly, the TRF-treated birds consumed, on average, 11.7% less food than the controls. This was manifested by an average reduction of 9.6% in body weight, 2.6-fold in visceral fat accumulation, and 6.5% in egg weight. Hen-housed egg production was reduced by 3.6% in the TRF group compared with the control, along the first 40 weeks of the follow-up (P < 0.05), and changed into a tendency of 0.7% higher egg production thereafter. Several parameters of egg quality showed significant improvement (P < 0.05) in the TRF group compared with the controls. A comparison of diurnal patterns of feed consumption revealed a higher rate of hourly consumption in the TRF group and increased consumption before dark in the control group. In conclusion, the reduced feed intake in response to the TRF treatment and loss in visceral fat accumulation supports the lack of a strong adipostat activity in chickens and different appetite regulation mechanisms compared with mammals. Therefore, future TRF studies in chickens should be adjusted by extending the ad libitum time window. The lower feed intake by the TRF-treated chickens compared with the ad libitum-fed controls seems to reduce the efficiency of egg production. Nevertheless, the improved egg quality and persistence of egg lay at the older age suggest that similarly to mammals, the TRF treatment delayed at least some of the negative impacts associated with advanced age.

The article considers the effectiveness of the use of mixed feeds with different levels of metabolic energy for the cultivation of larvae and fry of rainbow trout. The aim of the experiment was to establish the influence of different levels of energy supply of trout on its performance. For this purpose, five experimental groups were formed by the method of analogues. During the equalization period, the experimental fish consumed feed of the control group. In the main period, the level of metabolic energy in trout feed ranged from 14 to 18 MJ. As a result of the conducted researches it is established that the increase of energy content in compound feed for trout larvae and fry from 16 to 18 MJ contributes to the increase of their weight by 11.1 % (p < 0.05) and growth intensity - by 5.6-14.2 %, while the reduction of energy content to 14 MJ / kg contributes to a probable decrease (p < 0.05) in mass by 11.9%, and a decrease in growth intensity by 6.0-14.7 %. It is proved that the feed consumption per 1 kg of weight gain in trout larvae and fry, which received feed with an energy content of 18 MJ was lower by 5.1 %, and with its content of 14 MJ - 4.8 % higher compared to fish consuming feed with an energy content of 16 MJ / kg. The safety of the experimental fish throughout the experiment was close and ranged from 83.1 to 84.9 %. However, it is most economically feasible to grow trout that consume feed with a nutritional value of 16 MJ of metabolic energy, compared with a decrease or increase of this indicator to 14 or 18 MJ, respectively.

Abstract To realize the genetic potential of pig productivity and balance diets, it is perhaps to use various additives, including silicon-containing zeolite trepel. The novelty of the work - the use of zeolite in feeding as a preventive and therapeutic additive allows you to increase productivity and reduce the cost of feed and feed costs compared to similar additives. For the experiment, 4 recipes of mixed feeds were developed: one without the content of zeolite trepel and 3 with 3, 4, 5% of this additive. It is proved that the best dose of this drug is 3% of the mass of feed. It was found that the body weight gain in II group increased by 13.5%, in III group by 7.2%, and in IV group decreased by 4.41% compared to the control group. The addition of silicon-containing zeolite in the II and III experimental groups did not affect the consumption of mixed feed, and in the IV experimental group, a decrease in the consumption of mixed feed was observed. Feed consumption in the I, III and IV experimental groups decreased by 12.1%, 6.7% and 0.3%.

The expediency of using the probiotic drug Biolax-U in the rations of lactating and dry cows of Black-and-White breed has been studied and scientifically proved. The influence of this drug on the morphological and biochemical parameters of animal blood has been determined. The composition of the probiotic drug Biolax-U consists of eight strains of a balanced complex of living lactic acid bacteria, yeast and actinomycetes, as well as biologically active substances. For experimental studies conducted on 2 groups of cows have been selected by the method of pairs-analogs, the influence of feeding of feed have been prepared with the use of the microbiological drug with probiotic action Biolax-U on feed consumption, morphological and biochemical changes in blood has been studied. Analysis of the rations of cows indicates that the content of calcium, phosphorus, magnesium, sulfur and trace elements such as manganese, copper, zinc and cobalt in the feed has been reduced. It has been found by studies that the use of probiotic drug Biolax-U had the positive influence on the feed intake, digestibility and better assimilation of feed nutrients and contributed to the improvement of blood morphological and biochemical parameters. For example, in animals of the experimental group hemoglobin has increased by 3,6 % (Р < 0,05), red blood cells by 10,1 (P ≤ 0,05), the content of leukocytes by 4,43, carotene by 9,6, glucose by 3,4; reserve alkalinity by 15,6, calcium by 19,4 (P ≤ 0,01), and phosphorus by 18,4 % compared with the control group of animals. During the lactation significantly improved hematological parameters including alkalinity reserve by 5,11 %, calcium level by 11,1, phosphorus by 8,6, hemoglobin by 14,2 %, the content of erythrocytes by 12,3, leukocyte by 3,86, and carotene 11,1 % against the parameters of animals of control group. The improvement of morphological and biochemical parameters of blood of cows indicates about stimulating effect on hematopoiesis and the general clinical condition of animals that contributes to the improvement of metabolic processes when using feed prepared with the use of microbiological drug with probiotic action Biolax-U.

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.

The aim of this study was to assess the effects of two levels of clinoptilolite administered in feed (2% and 4%) on some selected performance indicators, metabolic utilization of basic nutrients and the health status of laying hens. The selected 24 Bovans Goldline hybrid laying hens were divided into three equal groups, two experimental groups (E1 and E2) and one control group (C). The laying hens were housed individually in cages with an automatic supply of drinking water, manual feeding, in a setting with controlled light and temperature regimens. Hens from individual groups were all fed a complete feed mix of the same composition and the only difference was in clinoptilolite supplementation: feed mixes for E1 and E2 groups contained 2% and 4% of clinoptilolite (commercial additive ZeoFeed) respectively, replacing the same amounts of wheat. The hens received feed mixes and drinking water ad libitum. During this 28-day experiment, feed consumption and the number and weight of eggs laid were monitored individually for each hen. At the end of the experiment, the balance test using the indicator method (Cr2O3) was performed in all eight hens in each of the groups. The results of balance tests were then used to calculate the metabolic utilization of selected nutrients (nitrogen, fat, ash, nitrogen-free extracts, starch, gross energy, Ca, P). After the balance tests, blood samples for haematological and biochemical examinations were collected via puncture of the vena basilica. The addition of 2% clinoptilolite to feed mix resulted in a highly significant (P ⪬ 0.01) increase in mean egg weight to 64.69 g, but the addition of 4% clinoptilolite in group E2 resulted in a highly significant (P ⪬ 0.01) decrease in mean egg weight to 62.20 g compared to the control (63.73 g). Moreover, daily feed mix consumption in group E1 decreased to 114 g per one laying hen/day compared to the controls (118 g per one laying hen/day). In group E2 (4% clinoptilolite), daily consumption of feed mix increased compared with the controls to 124 g. The 2% clinoptilolite supplementation of E1 group feed slightly increased metabolic utilization of fat, nitrogen-free extracts, starch and gross energy compared to group C. Results of haematological test of the hens’ blood showed significant changes in haemoglobin, whose values in groups C and E1 were significantly higher (P ⪬ 0.05) than in group E2. Differences in the values of the biochemical indicators monitored (total protein, glucose, cholesterol, triacylglycerols, calcium, phosphorus, magnesium and the AST enzyme) between group C and experimental groups E1 and E2 were not significant and remained within the range of reference values.

Currently, there is a rapid development of commercial salmon farming in Russia, which has grown almost 3 times in terms of production since 2013 and exceeded 116 thousand tons in 2020. In turn, this requires the appropriate development of the feed base and the development of methods for the effective use of fairly expensive fi sh feed. From these positions the involvement of the feed additive “Vinivet”, which is a waste of beekeeping in the feed production for fi sh as a protein additive is relevant. The feed additive “Vinivet” contains bee products such as bee bread and slumgum, a significant complex of vitamins, amino acids, macro- and microelements. The purpose of the work was to assess the influence of the feed additive “Vinivet” on the livability of juveniles, growth rate and feed consumption of rainbow trout of Steelhead salmon breed when growing in a recirculating aquaculture system. For the experiment juveniles with an average juvenile weight of 2,37±0,72 g have been selected, from which the control and 3 experimental groups have been formed. The control group has received a standard starting compound feed as the main diet, the 1st experimental group in addition to the main diet has received the additive “Vinivet” in the amount of 2,5 % of the mass of the main diet, the 2nd experimental group has received 5,0 % of the additive, and the 3rd experimental group in the first week received 2,5 % of the additive, and from the second week of studies the dose of the additive was increased to 5 %. The conducted studies have shown that the inclusion of the feed additive “Vinivet” in the feed when growing juveniles of Steelhead salmon is most advisable by introducing it at the dosage of 2,5 % of the mass of the main diet in the first week of cultivation, followed by the increase in the dose to 5,0 %, which allows achieving the highest fi sh productivity of pools in the recirculating aquaculture system compared to all variants of the experiment and by 24 % compared to the control group.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

An investigation was undertaken on 180 day-old Hy-line layer chicks to assess the effect of herbal products on feed consumption, egg production and profitability. The experimental chicks were randomly divided in three groups with three replicates in each and were housed in identical management and environmental conditions. Dietary treatments were prepared by addition of herbal liver stimulants such as Livoliv 250 @500 g/ton (D2) and Superliv @500g/ton (D3) in the basal diet (D1). Feed intake, egg production and mortality were recorded throughout the observation period of 50 weeks. Feed per unit of egg production, hen day percentage, additional income of supplemented diet over the basal diet were calculated. Average daily intake (g) of the diets per bird were observed as 59.19±1.05 g, 58.31±0.337 g and 57.67±0.163 g up to 20 weeks and 108.94±0.06 g, 109.01±0.05 g and 108.26±0.41 g during the laying period fed with D3, D1 and D2 diets respectively. Similarly, higher hen day egg % (76.9%) was recorded in the birds fed with Superliv supplemented diet (D3), followed by Livoliv supplemented diet (D2) (73.4%) and Basal diet (D1) (72.1%) with feed intake per unit egg production of 179.3 g, 178.1 g and 193.0 g, respectively. Total egg production was found higher with D3 (161.49 egg), followed by D2 (154.15 egg) and basal diet (151.45 egg) with layer house cumulative mortality only in D3 (3.75%). Additional profits of Rs. 35.18 and Rs. 12.86 in terms of egg selling over feed cost per layer were calculated for the bird fed with Superliv supplemented diet (D3) and Liveloliv supplemented diet (D2) than that of the basal diet.
