Abstract:The issue of rational nutrition of children is still extremely relevant and an effective factor in ensuring the preservation of the life and health of children. Pathological conditions associated with intolerance to certain components of food are increasingly common. Biologically complete products play an important role in the organization of rational nutrition of children, which can be created only in industrial production conditions. When assessing the chemical composition of experimental goat meat samples (… Show more
“…Statistical processing was performed in Microsoft Excel 2016 in combination with XLSTAT. Values were estimated using mean and standard deviations (Tokysheva et al, 2022;Rioja-Lang et al, 2020).…”
The sperm quality supplied by producers is an urgent problem in the field of livestock breeding. Therefore, monitoring the health of male producers and sperm quality is of great priority. The study aimed to assess the reproductive performance of bulls using laboratory, clinical, morphological, ultrasound and reflexological techniques. A total of 17 heads of Kazakh-white-headed, Holstein-Frieze and Simmental breeds were studied. The quality of sperm was evaluated by the laboratory, clinical, morphological, ultrasound and reflexological diagnostic methods were used to determine the physiological state of the genitals. The results revealed that 11 (65%) bulls were included with high and good reproductive bulls and 6 (35%) with reduced reproductive abilities. The reliability of the measuring method for the morphological development of the scrotum and ultrasound coincides with the data of sperm quality by 66.6% and studying sexual reflexes on a point scale by 50%. When assessing the male reproductive performance, measuring the morphological development of the testes, studying sexual reflexes on a point scale and ultrasound examination of the testes and their appendages are recommended.

“…− Sampling methods and their preparation for analysis were carried out according to GOST 13928-84 − The acidity was determined by titrimetric methods according to GOST 3624-92 − Fat determination was carried out by the methods specified in GOST 5867-90 − Determination of milk density was carried out according to GOST R54758-2011 − According to GOST 23327-98, the Kjeldahl method determined the mass fraction of the total amount of protein (GOST 3624, 1992;GOST 5867, 1990;GOST 54758. 2011, GOST 25179, 2014GOST 23327, 1998;Tokysheva et al, 2022) Tests on sheep's milk cheese were carried out in the research laboratory for assessing the quality and safety of food products at the Almaty Technological University (Almaty).…”
The article presents the results of a study on the effect of top dressing and feed additives based on humic substances on milk productivity, the quality of milk of sheep of the Kazakh fat-tailed semi-coarse breed, and the resulting cheese in pasture conditions. In total, 90 heads of sheep of the Kazakh short-tailed semi-rough-haired breed were used in the experiment. The Control Group (CG) of 30 sheep grazed on pasture grass, while two Experimental Groups (EG) of 60 heads were fed 300 g barley per day of barley, The second experimental group of sheep received a feed additive based on humic substances. As a result, after the first month of feeding, additional feeding had a positive effect on the daily milk yield of ewes, where the experimental group II was statistically significantly superior (P<0.05), i.e., it exceeded by 0.08 liters. In total, during lactation, the sheep of the second experimental group exceeded the control group by an average of 10.8% in average daily milk yield. Also, additional feeding affected the quality of milk and cheese, Thus, the indicators of sheep of the II experimental group were superior in terms of the fat content of milk (P<0.01) and cheese (P<0.05).
“…Despite the positive growth in life expectancy, it is worth noting that it does not correspond to the country's income levels. The life expectancy of the Economic Cooperation Organization countries, such as Chile and Turkey, with similar GDPs, is 80 years [3]. The analysis of food products presented on the market of our country has shown that the following areas are developing dynamically: the production of baby food products, therapeutic and preventive directions.…”
A recipe for cooked sausages of the herodietic direction using protein hydrolysate in the amount of 3%, 5%, and 7% of the mass of raw materials is proposed. The recipe is based on "Beef Sausage". Organoleptic evaluation of the prototypes showed that when protein hydrolysate was added in an amount of 7%, a specific taste characteristic of by-products was present in the prototype. Based on the sensory evaluation results, it was decided to continue the study of samples with the addition of 3% and 5% protein hydrolysate. The results of the study of the physicochemical parameters of the prototypes with the addition of protein hydrolysate 3% and 5%, showed the values of the mass fraction of protein 16.65% and 19.29%, fat 9.85% and 12.25%, carbohydrates 2.85% and 3.07% respectively, indicating an increase in the amount of protein and a decrease in the proportion of fat compared to the control sample. A significant increase in the content of such essential amino acids as lysine and valine and interchangeable amino acids as arginine, glycine, and serine in the test samples confirms that the protein hydrolysate introduced into the prototype is rich and well-balanced in amino acid composition. To study the effect of protein hydrolysate on the quality of meat products, the moisture binding capacity was determined, which was 3% and 5% in the experimental samples with the addition of protein hydrolysate – 75.62% and 79.13%, which is 3.4% and 8.2% higher than that of the control sample, respectively. The sample with the addition of 5% hydrolysate (80.01) has the greatest moisture-retaining ability, which is 9% higher than that of the sample with 3% hydrolysate and 15.8% higher than the control indicator. The study results of the fat-holding capacity in the samples also showed positive dynamics.
