Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to the field of feed production, specifically to the production of a feed additive.

State of the art

The use of dried microalgae Spirulina biomass in livestock feed in powder or tablets is known. This is described in the scientific literature by A.JI. noramyK, C.A. CeMeHOB CnHPyJIHHA B PAOHOHAX CBHHEŽ (SPIRULINA IN PORK DAVINY) Magazine. Cbhhoboactbo No.4, 2002. However, the dried microalga Spirulina does not produce the desired effect,

The essence of the invention

The object of the present invention is to improve the microbial balance of the digestive tract and the digestion of nutrients, while obtaining more livestock production.

The stated objective is achieved by the use in animal nutrition of a feed additive containing natural biomass of the microalgae Spirulina and additionally molasses in the following proportion (weight%): Spirulina biomass 6-33% and the remainder - molasses; it may also contain fructose (% by weight): 6-67%; BF with receiving biomass of microalgae Spirulina washed with water at pH 5.2 to 5.5, by vacuuming to 65-70% moisture and mixing with preserves heated to 47-67 ^Q C molasses. Experiments have shown that the microalgae Spirulina is very effective when it is in the form of fresh biomass. However, fresh microalgae biomass can remain active for up to 4 hours. After mixing the biomass of microalgae Spirulina with heated molasses and / or fructose to 47-67 ° C, the biomass is preserved and remains active for up to 18 months.

The addition of a mixture of biomass and molasses of the microalgae Spirulina, which has a phytobiotic (probiotic) and haemopoietic effect, improves the microbial balance in the ruminants, the digestibility of the nutrients in the feed and the activation of vital physiological processes in the macro organism. This results in a 6-8% increase in ruminant productivity. On average, one ruminant can take 10-30g of preserved molasses of spirulina spirulina per day.

Application of the Invention

The invention is illustrated by the use of Spindina for dairy cows, where lg

Spirulina (S) was preserved with 7g of molasses, and one milking cow received 16g of this preparation per day.

The test was performed with Lithuanian Black and White breed cows. Two groups were formed based on the age, lactation and productivity of the cows:

Control and Trial. Each group had 15 second to third lactating cows. The test took place between 60 and 120 days of lactation. Both groups were kept under the same conditions and fed the same feed, with only 1g of molasses preserved molasses of "Spirulina" biomass being added to the compound feed of the experimental group individually after 16g of microalgae each day. The test was conducted for the first 30 days in the barn and the next 30 days in the grazing period. At the beginning of the test and every 15 days thereafter, the cows were sent for control milking. Milk samples for chemical testing were taken every 30 days. GDZ-1 was taken from the cows at the beginning of the test and every 3 days thereafter every 3 days with the GDZ-1 probe. after morning feeding. At the end of the test, the digestibility of nutrients was investigated and blood morphological and biochemical tests were performed.

Studies have shown that the use of S in the diet of dairy cows has a positive effect on milk production. The control milking data of the cows obtained during the test are shown in Table 1.

The results of the study in Table 1 show that the effect of S on the productivity of dairy cows is noticeable after 30 days of testing, although positive changes in the additive are already evident after the first 15 days of testing. After 30 test days, 1.7kg or 5.6% more milk was obtained than those not receiving S. After 45 test days, the influence of S on cow productivity became even more pronounced. During this test period, cows in the test group produced on average 2.5kg or 8.9% more milk per day than cows in the control group. At the end of the test, after 60 test days, the cows in the test group had an average of 4.0 kg or 14.5% more milk per day than the cows in the control group. During these two months of the test, the average milk in the control group was 1726.5 kg and the cow in the test group received 1858.5 kg of milk, or 132 kg and 7.6%, respectively, compared to the cow in the test group. The milk composition (when n = l0) is given in Table 2.

The data in Table 2 show that S had a positive effect on the chemical and morphological characteristics of milk. After day 30 of the test, the milk fat content of cows receiving S increased by 0.86% and that of control cows by 0.32% or 0.54% less than that of the test group. Milk protein and lactose were not affected by S. At the end of the test, the milk fat content of the cows receiving S decreased from the test period to 30 days and reached baseline levels. Meanwhile, the milk fat content of the control cows was 0.34% lower than at the start of the experiment. This decrease in milk fat may be attributed to the change in cow keeping during the transition from barn to pasture. The results of the obtained studies indicate that S had no effect on milk protein content. At the end of the test, the influence of S on the lactose content of the milk becomes apparent. The milk sugar of the cows in the test group increased significantly by 0.24% more than that of the control group. This indicator indicates that the cows in the test group have better absorption of some of the nutrients in the diet and have more energy to produce dairy products. The use of S in dairy cows' diets provides an additional 17.59kg or 25.0% more milk fat, 5.25kg or 9.7% (P> 0.05) of milk protein and 9.12kg or 11.7 days of lactation. % lactose. SP has a positive effect on the amount of somatic cells (SLS) in cow's milk, and thus on milk quality. At the end of the test, the SLS in the milk of the cows in the test group was 135.2 thousand / ml, or 29.1% less than in the milk of the control group.

Haematological results showed that all blood counts were within physiological limits. Higher hemoglobin, erythrocytes and some neutrophils are observed in the blood of test group cows. This indicates that cows receiving S have undergone more intense vital processes. Correspondingly, cows in the test group had 5.6% more hemoglobin, 13.1% erythrocytes, rodent neutrophils 13.9% and segmented neutrophils 9.4% more than the control cows. These data suggest that S has haemopoietic activity and positively influences animal health.

It is found that 80-90% of the fiber, almost all water-soluble carbohydrates and pectins are digested in the large stomach. The end product of this fermentation is LRR (Volatile Fatty Acids). The results of the studies showed that the experimental species produced more LRR in the rumen contents of the cows and more were absorbed through the stomach wall. As a result, the cows in the experimental group received more energy needed to produce their produce. The total bacterial intake of S in cows was, on average, 0.261 µg / ml in the whole stomach over the control group, the total lactobacterial content was 0.341 µg / ml, the streptococcal content was 0.751 µg / ml and the yeast content was 0.341 µg / ml. All this shows that the phytochemicals contained in SP have a positive effect on the biochemical and morpholagic studies of the rumen, and the preparation has a phytobiotic effect.

Nutritional digestibility studies in the diet indicate that Spindina improved the digestibility of the nutrients S in the feed, most influencing the digestibility of crude protein and crude fat. All of this can be explained by the probiotic effect of the preparation. Increasing the amount of microorganisms in the gastrointestinal tract, with a probiotic effect, improves the digestibility and absorption of nutrients in the feed. As a result, the dairy cows in the test group received more energy needed to produce milk.
