Description

Currently, natural, organic preparations that increase the digestibility and uptake of nutrients in feed are characterized by their probiotic and immunomodulatory properties. We can categorize them all into probiotics, prebiotics and phytobiotics. These are some of the most promising, relatively new, rapidly growing natural and organic preparations developed by biotechnology, which improve the microbial balance of the gastrointestinal tract, animal health and production quality. (Hamidreza and Wemer, 2005; TpąaoBa h ΛΡ-, 2001)

Phytobiotics include herbal preparations and their phytochemical constituents. Some phytochemicals have the ability to bind cholesterol, reduce the absorption and active elimination of cholesterol, have secretomotor and secretolytic properties, strengthen the animal's immune system, kill pathogenic microflora, and reduce ammonia and hydrogen sulfide concentrations in animals.

Algae also belong to the group of phytobiotics. Cyanobacteria Spindina platensis is not only a rich source of vitamins, amino acids, phytohormone enzymes and trace elements, but also increases their uptake from feed. In this way, additional phytochemicals are introduced into the body and the amount of non-absorbed feed is reduced (Goksan et al., 2007; Patil et al., 2008; EropoBa h ąp., 2006; Πετρ »κοΒ, 2007).

When preparing feed additives and supplements, the aim is to make the formulations dry and bulky, convenient to feed, easy to use for feeders and livestock.

The purpose of the present invention is to provide a dry bulk available for use in flour and granular feeds, a feed additive that positively affects animal physiological processes and yields higher quality animal production of farm animals.

The stated objective is achieved by the use in animal nutrition of a feed additive containing natural biomass of the cyanobacteria Spirulina Platensis, containing, by weight, not less than 12,5% phycocyanin blue pigment, preserved molasses and meal (bran, ground cereals or ground cereal mixture). The algae is preserved in molasses at the following ratio (% by weight): the cyanobacteria Spirulina platensis has a biomass of 13-40 and the rest is molasses. Before conservation, the biomass of the cyanobacteria Spirulina platensis is washed with potable water and vacuumed to 70-75% moisture. The molasses is heated to 36-42 ° C. the vacuum biomass of cyanobacteria Spindina platensis is added to the heated molasses with stirring.

Heat to 36-42 ° C with stirring for 20-35 minutes. The biomass of canned molasses Spirulina Platensis remains active for up to 12 months.

The resulting canned molasses mass is kept for at least 24 hours, during which the algae is saturated with molasses and its cell is not broken by granulation but not longer than 12 months. Evenly 3-5% of the molasses-blue-green algae mass is injected into the flour and granulated. A feed additive is obtained, containing 50 - 255 g of 1 g of 70 - 75% moisture content of the cyanobacteria Spirulina platensis biomass. The resulting feed additive is non-peeling, dust-free, easy to transport and store, and easy to use for livestock farmers. The resulting bulk feed additive remains active for 6 months.

This aim can be achieved by the use in animal nutrition of a feed additive containing the natural biomass of the cyanobacteria Spirulina Platensis, containing in the dry state at least 12,5% blue pigment phycocyanin, dried in a drying oven to 9,5 to 14,0 air dry. % moisture and flour feed (bran, ground cereals or a mixture thereof). Before drying, the cyanobacteria Spirulina platensis biomass is washed with potable water and vacuumed to 70-75% moisture. Dry in the oven to 36-42 ° C. The dried biomass of Spirulina Platensis remains active for 36 months.

Air dry Spirulina Platensis biomass 3 - 15% evenly mixed into flour feed, which can be granulated. A feed additive is obtained, containing 6.7-33.3 g of 1 g of biomass of the cyanobacteria Spirulina platensis. The resulting feed additive does not peel, dust, and is convenient for storage and use. The resulting bulk feed supplement remains active for 24 months. ,

By supplementing the animal diet with the mixture of cyanobacteria Spirulina platensis biomass and feed, vital processes in the farm animals are activated, the microbial balance of the digestive tract and the digestibility and health of the feed nutrients are improved. As a result, the productivity of farm animals increases by 7-19%. On average, 2-300 g of dry, bulk feed can be consumed per animal per day.

A granular preparation of Spirulina Platensis was used to illustrate the invention for dairy cows and pregnant pigs. In a study of dairy cows, a preparation containing 10 g of Spirulina platensis air dry substance was used. One dairy cow received 20 g of this preparation per day. In a study on pregnant pigs, a preparation containing 100 g of granulated feed in Spirulina platensis was used. One sow received 200 g of preparation per day.

TESTING WITH DAIRY COWS

Depending on the age of Lithuanian Black and White cows, lactation productivity was formed in two groups: control and experimental. Each group contained 10 lactating cows of III - IV. The test was conducted on cows from 70 to 130 days of lactation. All groups of animals were housed under the same conditions and fed the same diet, with the cows in the experimental group receiving, individually, 20 g of granulated Spirulina platensis containing 2 g of airborne Spirulina platensis biomass on each day of feeding. At the beginning of the test and thereafter every 15 days, control milking of the cows was performed. Milk samples were analyzed using state-of-the-art methods of SE Dairy Research. Milk fat, protein, lactose and urea were determined by infrared mid-range absorption (LST ISO 9622) and somatic cell count in milk was determined by fluoroptoelectronic method (LST EN ISO 13366-3).

Morphological and biochemical parameters of blood were analyzed for the physiological status of cows. Blood was drawn from the tail vein into vacuum tubes (Venoject II, Terumo Europe, Belgium) at the start of the test, 1 month later. and after 2 months i.e. at the end of the test, 2 hours later. after morning feeding. For morphological examination, blood was drawn into tubes containing the anticoagulant EDTA (K2), and in the case of biochemical tests, into tubes containing no anticoagulants. Hemoglobin was determined by colorimetric method and erythrocytes and leukocytes were counted in the Goriajev cell. Glucose was determined by reflex photometer Accutrend GCT 2001 (Germany), total protein was determined by refractometer RL3 (Poland).

The contents of the rumen of the stomach with the GDZ-1 probe were taken from cows at the beginning of the caudoventral part of the rumen of the stomach and every 3 days after 20 days. after morning feeding. The following parameters of the rumen contents were investigated: pH was determined by the electrometric method pH-meter CP-315; bacterial reduction activity was evaluated by G. Dirksen method; glucose-acid reaction was performed by Einhom saccharometer according to J. Bakun's method number of infusions was analyzed by Fuks-Rozenthal chamber according to JA Schultz method total volatile fatty acid content (LRR) was determined by distillation of rumen contents by Markgam apparatus by V.V. (OM) digestibility was investigated in vitro by the Stage I method.

The total rumen contents of cows were analyzed for total bacterial count (BBS), lactate-fermenting (LFBS) and cellulolytic bacterial count (CBS) using N. O. van Gylswyk's method for culturing obligate anaerobes.

Aerobic and facultative anaerobic bacteria, lactobacilli, streptococci, yeast were determined by examination of the contents of the rumen and by the plate method. Nutrient agar was used for aerobic and facultative anaerobic bacteria, MRS agar for lactobacilli, Slanetz-Bartley agar for streptococci, and Sabur agar for yeast (Liofilchem, Italy).

The research data were processed by statistical analysis method with statistical package R 2.2.0.

Statistical analysis was done by Student's Test. Results are considered reliable at p <0.05

The results of the control milking and the qualitative indicators of milk composition obtained during the test are given in Table 1. The results of the study showed that Spirulina platensis had an effect on the daily milk yield of dairy cows after the first 15 days of testing. While the milk production of control cows remained almost unchanged during this period, the cows of the control group produced 0.9 kg or 3.84%. more milk than at the beginning of the test. After 30 days of testing, cows in the test group were milked at an average of 1.58 kg or 7.48 percent. more milk per day than in the control group. After 45 days of testing, 1.64 kg or 7.0% of the cows in the test group were milked. more milk per day than in the control group. At the end of the test, after 60 test days, the average daily intake of the cows in the test group was 3.33 kg or 14.4%. more milk than cows in the control group. When comparing the milk yield of this period with the beginning of the test, the daily milk yield of the experimental group was 2.96 kg or 12.62%. and 1.54 kg, or 6.7 percent, in the control group. lower.

According to the results of the study, the preparation of cyanobacteria Spirulina platensis has an influence on the chemical composition of milk. The milk fat content of the control group cow's milk remained almost unchanged during the test, increasing by 0.14% in the test group. Milk protein content decreased by 0.19% in the control group and increased by 0.13% in the control group. ,,

At the end of the experiment, the number of somatic cells in the milk of control cows was 66.75 thousand / ml or 57.5%. more than in the milk of the experimental group cows. This shows that blue-green algae has a positive effect on the quality of cow's milk and the health of the udder.

Summarizing the results of Table 1, it can be stated that the preparation of the cyanobacterial Spirulina platensis activates the secretion of the mammary gland in dairy cows, the amount of milk produced per day may increase by 14.4%. During the 60 days of this trial, the cows in the test group received an average of 92.1 kg of milk, 5.49 kg of milk fat, 4.43 kg of milk protein and 3.53 kg of milk sugar more than that of the control group.

The rumen contents were determined to show that the biochemical parameters of the rumen of both groups of cows were within the physiological limits at each stage of the study. The results of the rumen study are shown in Table 2. High rumen contents showed that 32.9% of cows fed the cyanobacterial Spirulina platensis supplement after the first month of testing. increased (p <0.05) volatile fatty acids (LRR), after the second month of test - by 9.4%. Volatile fatty acids are the most important source of energy for cows. We believe that the animals in the test group received more energy needed for milk synthesis.

The glucose fermentation test (Table 2) showed that 24% of the rumen of the test cows was in the rumen. more intensive fermentation processes than control animals.

The rumen of bovine animals has an abundant and diverse population of anaerobic bacteria, infusors and fungi. It rapidly colonizes the feed that enters the rumen. Due to the active activity of microorganisms, bovine animals receive about 70 percent. energy materials needed to sustain vital processes and produce products. Infusions are very important for biological processes in the stomach and are involved in all metabolic processes. Due to their abundance and agility, they form microcirculation, purify, stir and crush the contents of the rumen. This increases the surface area of the feed, creating optimal conditions for bacterial enzymes. The number of infusions of cyanobacterial Spindina platensis after the first month of treatment in the rumen of the experimental group of cows was 37.55 thousand / ml or 37.75%. (p <0.05), and after the second test month 15.43 thousand / ml or 11.24 percent, respectively. more than in the rumen contents of control cows. In addition to breaking down the feed, the microorganisms in the rumen of cows synthesize their body proteins from the substances in the high rumen, then digested by the enzymes and digested by the body's digestive tract. Microorganism proteins are closer to cows than feed proteins. The overall increase in rumen microorganisms in the test animals is very significant. The digestibility of the organic matter of the feed by incubation of the feed with the rumen contents of the cows showed that the cows in the test group digested the organic matter of hay, hay and silage respectively 7.4%. (p <0.05),

2.6% and 5.6 percent. (p <0.05) better than control cows. This explains the improved digestibility of the nutrients in the diet and increased milk yield due to the influence of cyanobacteria.

Anaerobic microorganisms in the rumen are actively involved in the digestion of organic matter. The rumen contents were found to increase the mean total anaerobic bacteria by supplementing the cows' diet with supplementation of cyanobacterial Spirulina platensis. One month after the start of the test, the BBS test group contained 6.3 percent in the rumen of cows. higher (p <0.01), and after 2 months 8.6%.

higher (p <0.001) than in the rumen of control cows. In the rumen of the test cows, the average lactate-fermenting and cellulolytic bacterial counts changed very little.

The cyanobacterial preparation used in the study had an effect on aerobic bacteria, microaerophilic lactobacilli and facultative anaerobes. The total number of aerobic and optional anaerobic bacteria in the rumen of cows was 5.2%. more than the control cows in the rumen contents. Correspondingly, the content of microaerophilic lactobacilli in the stomach of the cows of the experimental group after the first month of testing was 6.9%. more (p <0.001) and after the second

10.6 percent more (p <0.001) than in the rumen of the control cows. The content of other lactic acid-producing bacteria, streptococci, was 12.2% in the rumen at the end of the test. (p <0.001) was higher in the test group than in the control group. Correspondingly, the yeast test group contained 6.8 percent in the rumen of cows. more than the control group cows.

Microbiological results obtained in the rumen of cows show that the Spindina platensis additive has a pobiotic effect and increases the content of beneficial microorganisms in the rumen contents of cows.

Hematological tests showed that the blood parameters of the cows of both groups were physiological, high enough and characterize good health of cows. If in the test, after the first month of the experiment, the blood levels of red blood cells of both groups of cows were almost equal, the hemoglobin and red blood cells were 12.5%, respectively, at the end of the test. (p <0.05) and 6.8%. more than in the control group. This indicates that the cows in the experimental group underwent more intensive oxidative processes. The results of the study showed that the preparation has an effect on haemopoiesis.

Conclusions:

1. Airborne biomass of cyanobacteria Spindina platensis is resistant to granulation, positively affects cow health and activates mammary gland secretion in dairy cows. Dairy cows produce more quality produce.

2. The cyanobacterial Spindina paltensis feed additive has probiotic activity, improves microbial balance of feed nutrients digestibility activates fermentation processes. It is haemopoietic.

SOWS

Two (control and experimental) groups of analogous sows of 6 animals each were formed. The Landrass breed sows used in the study were inseminated with the semen of Diurok and Petretrian crossbreeds. The sows were tested from 82 days of gestation and continued until weaning. Piglets were weaned on the 28th day after birth. All pigs used in the experiments were reared under the same standardized feeding and housing conditions, except that the pigs in the test group were supplemented with granulated cyanobacteria Spindina platensis daily at a daily dose of 2 g to 75% in addition to the normal diet. moisture for cyanobacterial biomass.

The effects of Spirulina platensis on reproductive performance and suckling piglet growth performance were assessed as follows: fertility (units), birth weight (kg), birth weight (kg), piglet weight at day 21 (kg), piglet weight At 21 days of age (kg), weaning piglet nest weight (kg), weaning piglet weight (kg), daily piglet gain (g), piglet retention percentage Based on the weighing data, the daily weight of piglets was calculated.

Sows' milk samples were taken 4 hours later. and 14 days after parturition. The milk samples were analyzed by an accredited laboratory using the methods approved by the State Enterprise "Dairy Research". Milk fat, protein and lactose levels were determined by infrared mid-range absorption (LST ISO 9622), LactoScope FTIR (FT1.0. 2001; Delta Instruments, The Netherlands). Conditional milk yield of sows was determined by nest weight at 21 days. after calving.

At the end of the experiment, the digestibility of the sows was examined and the blood samples of the sows were collected for haematological examination. Nutrient digestibility of sows' ration was determined using TiO ₂ indicator according to its concentration in feed and faeces. Based on the chemical analysis of feed and faeces, the digestibility coefficient was calculated. The following was determined in feed and faeces: total nitrogen, protein and non-protein nitrogen - Kjeldahl method; dry matter content - drying at 100-105 ° C; crude fat - Soxhlet method; crude fiber by the Kursner method.

Morphological indices of sows were determined on a hematological apparatus SWELAB-AC920 EO + (2004; Boule Medical AB, Sweden) and biochemical indices were performed on a semi-automatic biochemical analyzer Screen Master Plus (2002; Hospitex Diagnostics S.A., Italy).

The research data were processed by statistical analysis using the statistical package R 1.7.1. (Http://www.r-project.org) and the WinExcel program. The reliability (p) of the difference in arithmetic means is determined by Student. Results are considered reliable at p <0.05.

Reproduction data for sows is shown in Table 1. As shown by calving data, the fertility of the sows in the test group was 1.83 piglets lower than that in the control group, but the birth weight and the birth weight were higher in the test group sows by 0.25 kg or 1.53%, respectively. and 0.27 kg or 19.85 percent.
