The results of certain studies indicate that a relation exists between the quality of colostrum and milk and the correct balancing of energy and protein in the diet for cows in particular during the last three weeks before parturition. The aim of this study was to determine the effect of fat additives offered to cows during the dry period on the composition and physico-chemical properties of colostrum and the pre-colostrum secretion. 24 cows were assigned to one of three groups. Group I - control, received no feed additives; II - received feed supplemented by a mixture of fish and rapeseed oil in a 1:1 ratio, III - received feed supplemented by protected fat (Brgafat). In both cases the addition of fat amounted to 360g, i.e. 2% DM. All animals received a PMR concentrate in quantities calculated according to the INRA system. From all the cows samples were taken about 48 hours before parturition of the pre-colostrum secretion and directly after calving of colostrum from the first, complete milking. The samples taken were analyzed for basic composition, for the overall number of microorganisms (ONM), somatic cell count (SSC), content of urea, coagulation time after adding rennet, thermo stability as well as potential (oSH) and active (pH) acidity. The results of the studies conducted indicate that the composition and physico-chemical properties of colostrum and pre-colostrum is differentiated. Offering protected fat as a feed additive for cows during the last three weeks of the dry period had a significant effect on the share of dry matter and crude protein in the colostrum produced. The addition of a mixture of fish and rapeseed oil did not have a similar effect.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Effect of Genetically Modified Feeds on Physico-Chemical Properties of PorkThe objective of this study was to evaluate the effects of genetically modified (GM), insect-resistant Bt maize (MON810) and the meal made of glyphosate-tolerant soybean (Roundup Ready MON40-3-2) used as the dietary components for pigs on the physico-chemical properties of meat. Forty-eight fatteners derived from Polish Landrace x Polish Large White sows mated to a Duroc x Pietrain boar were used. All animals received isonitrogenous and isoenergetic diets containing or not containing the genetically modified components. The design of the experiment was as follows: group I (control) - non-modified soybean meal and maize; group II - GM soybean meal and non-modified maize; group III - non-modified soybean meal and GM maize; group IV - GM soybean meal and GM maize. The examination of the pH values of loin and neck muscles indicated no statistically significant differences between pigs fed diets containing non-transgenic or transgenic feeds. No statistical differences were observed for water holding capacity (WHC) within dietary treatments. The introduction of transgenic maize and soybean meal into pig diets did not significantly affect the a* colour parameter of loin as well as neck muscles. The use of transgenic maize or soybean meal did not cause significant changes in the L* colour value of loin. Results obtained for neck muscles were more differentiated, possibly due to the natural heterogeneity of this primal cut. Pigs which had consumed the transgenic diet exhibited slightly decreased lipid stability of loin, as indicated by thiobarbituric acid reactive substances (TBARS). The decrease was statistically significant only in the case of muscles from group II. The addition of feeds derived from genetically modified crops into pig diets did not significantly affect the stability of neck muscle lipids; however, TBARS values of these muscles were twice those of loin muscles.

Poultry farming using modern technologies requires the employment of veterinary preparation for the prevention of infectious diseases and also feed additives for the improvement of metabolic functions and correction of body resistance. The article presents the results of clinical trials of feed additives in the form of an ionic solution concentrate of the biologically active nanosilicon "Arsil". The clinical study was performed on healthy ten-day-old broiler chicken, cross "Cobb-500", organized into three groups of 20 heads each: Group I received a feed additive at a dose of 0.5 ml per 1 liter of water, group II – at a dose of 1.0 ml per 1 liter of water and group III was the control group (on a regular diet, without feed additives). The use of the studied feed additive was carried out by watering with water for 30 days. Poultry of all groups were fed with identical feeds in accordance with regulatory requirements taking into account the age of the bird. The clinical condition of the bird was monitored daily, control weightings were performed once a week and blood samples were taken for laboratory tests on days 15 and 35 of the experiment. At the end of the experiment, a diagnostic slaughter of birds of all groups and a complete pathological autopsy with selection of material for histological examination were performed. Studies have shown that the use of the feed additive "Arsil" contributed to weight gain and average daily gain, improved the feed conversion and the tendency for the growth of the concentration of hemoglobin, hematocrit and erythrocytes in broiler chicken from the experimental groups compared with the control group at the end of fattening. The structure of the internal organs of birds of all studied groups is preserved, macroscopic changes in organs and tissues are not detected. An increase in the coefficients of mass of immune-competent organs in broiler chicken fed the feed additive "Arsil" compared with the control group was found.

Some important physico-chemical properties of water of major ponds of Comilla Town were studied to evaluate the water quality. Eight water samples were collected during the dry period (March 2005) from eight major ponds of Comilla Town (Ranir dighi, Mandir dighi, Nanuar dighi, Fauzdari dighi, Modina dighi, Dargabari dighi, Darma Sagar and Thakurpara). The result revealed that all the chemical constituents, except a few, are beyond the recommended limit for different uses. Higher value of pH (at Dargabari dighi, Darma Sagar dighi), OM (at Thakurpara dighi, Fauzdari dighi and Modina dighi), NH4+ concentration (at Ranir dighi, Mandir Dighi, Fauzdari dighi, Modina dighi and Dargabari dighi), and lower value of DO (at Fauzdari dighi and Modina dighi) may due to continuous disposal of kitchen wastes, organic wastes, sewage running and fall of twigs as well as extensive used for bathing, washing cloths and utensils etc. All indicate eutrophication and affect community health and hygiene and also create aesthetic problem in the locality.

The question of the need for separate administration of feed additives’ components that are antagonistic from the point of view of their chemical properties and physiological effects has long been debated among researchers. The authors have proposed a new supplement based on chelate compounds, which components’ effect on the organism of laboratory animals has been partially considered earlier. However, the assessment of the components’ effects on the morphology of the excretory and reproductive systems’ organs has not been studied. In this regard, the work considered the effect of feed additive components with separate introduction of chemically and physiologically antagonistic components on the pathoanatomical picture, as well as the microstructure of the kidneys and testes of laboratory mice to assess potentially negative effects on the excretory and reproductive systems. The supplement was administered orally at various dosages. The organ structure was assessed after 1, 2 weeks and 1 month. The microstructure of the kidneys and testes was histologically studied in the experiment and control. The negative influence absence of the supplement components in the entire range of applied dosages is shown. The absence of visible deviations of the pathoanatomical picture during autopsy of experimental animals was noted.

ABSTRACT: This study aimed to analyze the effect of phytogenic additives based on cardol, cardanol, and ricinoleic acid on the physico-chemical qualities and biochemical parameters of Holstein cow milk. Nineteen animals were divided into the control (GI) and treatment (GII) groups. Prior to the beginning of the experiment, sodium monensin was removed from the feed provided to the animals. This study consisted of two phases. In the first, animals from GI received the standard diet, without additives, while animals from GII received the standard diet supplemented with 10 g of phytogenic additives for 60 days. At the end of the first stage, the animals remained 30 days without receiving additives and in the second phase the groups were inverted, and the GII again received the phytogenic additive during the subsequent 60 days. Physical-chemical analyzes of milk were performed at moments 0, 15, 30, 45 and 60 days of the experiment and the blood parameters at times 0 and 60 days of the experiment were evaluated. There was no significant difference for the treatment x time interaction in any of the variables, but there was a trend between groups for the CCS parameter and there was a statistical difference for the protein, as well as for the AST. In this study it is observed that the addition of phytogenic additive modulating rumen fermentation based on cardol, cardanol and ricinoleic acid does not compromise, in general, the quality of milk, with positive results for some specific parameters such as protein content and aminotransferase.

The article presents the results of research on the study of the raw milk properties of cows when adding an energy feed additive (ECD) based on activated zeolite to the diets. The work was carried out in the conditions of the MTF "Smak Kors" RT. The results of the study of the qualitative composition of milk-raw cows showed that ECD contributed to an increase in MJ in group I by 0.09 %, in group II-by 0.15 %, in group III-0.22 % (P<0.01) in relation to the control. According to the content of MDB in milk, the difference in the indicator was at the level of 0.04-0.14 %, respectively. The improvement of the quality composition of the raw materials had a positive impact on the cheese suitability. It should be noted that the positive effect increases with an increase in the dose of the test feed additive. The best cheese-making properties were characteristic of the milk of cows of the third experimental group. In them, under the action of rennet, a dense clot was obtained from the milk of 80.0 % and a loose clot was obtained in 20.0 %, and the milk had a short clotting time of 15.3 minutes. The milk of the cows of all experimental groups met the requirements of the desired type II.
