The aim of the study was to investigate the effect of the partial replacement of wheat with bakery waste in compound feed on slaughter characteristics, quality and composition of meat in a heavy population of domestic quail. A control group (n = 90), I experimental (n = 90), and II experimental groups (n = 90) quails from meat-producing population WG were formed, respectively fed with basic feed, 5% and 10% replacement of wheat in the feed with extruded baking waste. A slaughter analysis, qualitative and chemical analysis of the meat of male and female representatives of the three experimental groups was performed. The replacement of 5% and 10% of the wheat in the compound feed with extruded bakery waste does not have a negative effect on the slaughter characteristics of the studied quail population. No relationship was observed between the studied physicochemical characteristics of quail meat and the addition of 5% and 10% extruded bakery waste. A similar effect is not observed with regard to the color characteristics of the meat. An exception is the Chroma (C*), where there is a tendency to higher values on the basis of experimental groups. With an increasing proportion of wheat substitution with extruded baking waste, the fat content in breast meat increases (P<0.001). The study leads to the conclusion that the replacement of up to 10% of wheat in the combined feed for quails with extruded bakery waste does not adversely affect the slaughter characteristics, quality, and nutritional value of quail meat.

The effects of graded levels of corn distillers dried grains with soluble (DDGS) as partial replacement for soybean meal in diets for broilers were observed. In the first experiment 900 males of ROSS 308 were used and they fed diets with 0, 60, 120 and 180 g/kg DDGS in grower diets (Control group, D6, D12 and D18) from 9th to 35th day of age. In the second experiment 800 broilers both sex of COBB 500 were used and they fed diets with 0 and 200 g/kg DDGS in grower diets (Control group and D20) from 9th to 35th day of age. Until age 30th day there were not significant differences among the groups in live weight in the first experiment. But at 35th day of age the live weight of chickens fed 60 and 120 g/ kg DDGS (2498.5 g and 2496.3 g) was significantly higher (P < 0.05) than in Control group (2425.9 g, without DDGS). In the second experiment, from 23th to 35th day of age significantly higher (P < 0.05) live weight had group fed diet without DDGS in comparison with chickens fed 200 g/kg DDGS. The difference between groups at 35th day of age was 75.7 g. Feed conversion ratio was similar in all groups in both experiments. There was not observed significant effect of DDGS on weight and proportion of abdominal fat. Feeding DDGS had significant effect (P < 0.05) on decrease the lightness (L*) of breast meat in the first experiment, which was not confirmed in the second experiment.

In this paper the effect of extruded rapeseed meal on the performance and sensory quality of the breast meat of broilers was investigated. The experiments were performed with hybrid line ROSS 308. The control group was fed soybean meal, and two levels of extruded rapeseed meal were added in experimental groups, 4% and 8% during a period of 42 days. Final body masses of chicken in the experimental groups were lower for 1.79% and 3.05% than the control group. Conversion of feed was satisfactory in all groups, and the best in the control group. Including extruded rapeseed meal in the meal did not show negative effect on the sensory quality, the smell and the colour, of fresh breast meat. Sensory quality (smell, taste and sensitivity) of heat-treated breast meat of the chickens in the control and experimental groups was marked as "very good", or optimal.

Abstract In order to improve the nutritional value of fish products and intensify metabolic processes, various micronutrients are added into fish products. They enrich the products with proteins, vitamins and minerals and reduce the calorie content. When developing a recipe for fish products, the possibility of partial replacement of wheat bread with flaxseed bran with seeds and water with turnips was analyed. The addition of flaxseed bran with seeds and turnips can enrich the product with dietary fiber, micro - and macroelements, vitamins. To determine the optimal percentage of plant raw materials, samples with the addition of linseed bran with seeds and turnips (10, 20 and 30%) were analyzed. A higher percentage has a negative effect on the organoleptic properties of the product.

The objective of this paper is to investigate the effect of multiphase feeding, i.e. the effect of different mash feeds with multi-phase protein reduction, on growth, main carcass parts and nitrogen content in faeces of broiler chickens. The experiment was conducted on 1216 chickens of Ross 308 provenience, separated by sex. The experiment lasted for 42 days and the standard technology was used. The groups differed in a type of a mash (treatment) given in the starter period, as follows: T1 (control group) was given a mash with 23% crude proteins from day 1 to day 21; T2 - a mash with 23% proteins from day 1 to day 7, followed by a mash with 21.5% proteins given from day 7 to day 21; T3 - a mash with 23% proteins from day 1 to day 14, followed by a mash with 21.5% proteins given from day 14 to day 21; T4 - mashes changed every three days, having 23%, 22.55%, 22.10%, 21.65% , 21.20%, 20.75% and 20.30% of crude proteins, respectively. Slaughtering performance was investigated on a total of 64 broiler chickens, with eight male and eight female chickens used separately for each of the treatments. Nitrogen content in faeces was determined using the pooled sample of faeces. The obtained results showed some differences in the average daily growth of the male and female chickens when comparing the control (T1) and the experimental groups. Those differences were not statistically significant. However, when comparing the male-only groups, it was determined that the experimental group T4 had statistically significantly higher growth than T2 and T3 group. The effect of the multi-phase feeding programme on the breast, thigh and drumstick share of both male and female broilers was not significant. The applied multi-phase feeding programmes resulted in a reduction in the nitrogen content in the faeces. Considering the obtained results, it can be concluded that the multi-phase feeding programmes had no negative effect on the growth and slaughtering performances of broilers. This goes in favour of these programmes, since they can result in some positive economic and environmental effects of production.

The study was conducted to evaluate the effects of partial replacement of soybean meal (SBM) by 15% raw or fermented rapeseed cake (RRC or FRC) to broilers’ diets on growth performance, nutrient utilization, methane emission, and breast muscle fatty acid (FA) composition. A total of 420 one-day-old female Ros 308 broilers were used in three independent experiments (300 birds in the first experiment and 60 in the second and third experiments). In each trial, three treatments were set up: a control group (without rapeseed), and diets replaced soybean meal with 15% addition of RRC or FRC. Birds fed the FRC diet experienced no effect (p > 0.05) on performance or nutrients utilization. Methane emission and total methanogen population in the ceca was decreased (p < 0.05) with the FRC diet. The concentrations of n-3 and n-6 FAs in the breast tissue of fourteen-day-old birds were not affected (p > 0.05) by FRC. However, the n-6/n-3 ratio in the breast muscle of 28-day-old birds was reduced (p < 0.001). In conclusion, the replacement of SBM by FRC in the broiler diets did not show any unfavorable effects on performance or nutrient utilization. Furthermore, the breast meat FA profile was improved, methanogen counts significantly decreased, and methane emission was limited.

Probiotic Preparation

In the experiment were verified the application of probiotic preparation through a water supply for feeding of cock’s hybrids Ross 308, Hubbard JV and Cobb 500 in the chemical composition of the most valuable parts of the carcass. Probiotic was based on the strain Lactobacillus fermentum with containing of 1.109 cfu.g−1 and potentially components of maltodextrin and oligofructose in 1% concentration. Length of feeding period was 42 days. Cocks were fed an ad libitum with the same starter mixture HYD-01 to 21th day and from 22nd to 42nd day of feeding with mixture HYD-02 in powdery form. The average of protein content of breast muscle was highest in Hubbard JV hybrid (23.93 g.100 g−1), lower in Cobb 500 hybrid (23.90 g.100 g−1) and lowest in Ross 308 hybrid (23.73 g.100 g−1), without significant differences (P ≥ 0.05) between hybrids and hybrids groups. Effect of probiotics had increased the protein content (P ≥ 0.05) in breast muscle of Ross 308 and Cobb 500 cocks and at the Hubbard JV only lower doses application during the feeding. The average of fat content in 100 g of breast muscle was lowest in Cobb 500 hybrid (1.09 g), higher in Hubbard JV hybrid (1.28 g) and highest in Ross 308 hybrid (1.35 g). Effect of probiotic to reduce fat content in breast muscle of cocks was at Ross 308 hybrid (1.33 and 1.23 g.100 g−1), Cobb 500 hybrid (0.98 and 1.02 g.100 g−1) and in second experimental group at Hubbard JV hybrid (1.03 g.100 g−1) statistically significant (P ≥ 0.05) in compared with control group, but significantly (P ≤ 0.05) between hybrids Cobb 500 and Hubbard JV in the first test groups. The average of energy value in 100 g of breast muscle was highest in Hubbard JV hybrid (449.24 kJ), lower in Ross 308 hybrid (448.40 kJ) and lowest in Cobb 500 hybrid (441.45 kJ), without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The average of protein content of the femur was highest in Ross 308 hybrid (18.56 g.100 g−1), lower in Cobb 500 hybrid (18.42 g.100 g−1) and lowest in Hubbard JV (17.54 g.100 g−1) without statistical significance (P ≥ 0.05). Significant differences (P ≤ 0.05) of the femur were found at lower dose of probiotics between cock’s hybrids Hubbard JV (16.95 g.100 g−1) and Ross 308 (18.48 g.100 g−1) in the protein content. The average of fat content in the femur was highest in Ross 308 hybrid (10.58 g.100 g−1), lower in Hubbard JV hybrid (10.51 g.100 g−1) and lowest in Cobb 500 hybrid (10.29 g.100 g−1) without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The higher fat and protein content in 100 g of the femur in Ross 308 hybrid was ensured the highest energy value (710.88 kJ), lower in Cobb 500 hybrid (696.40 kJ) and lowest in Hubbard JV hybrid (689.77 kJ) without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The verified probiotic preparation in the final analysis had not negative effect on the chemical composition of the most valuable parts of the carcase cock’s hybrids Ross 308, Hubbard JV and Cobb 500.

The results of researches on the development of new mineral feed additives based on raw materials produced by Uralchem and the study of the eff ectiveness of their use in the rations of lactating cows have been presented in the article. The experiment has been carried out in the conditions of LLC “PF Barabinskoe” in the Dalmatovsky area in the Kurgan region where 3 groups of lactating cows of Black-and-White breed have been formed. Animals in the control group have been received the ration adopted in the farm, the 1st experimental group with the additive RusMA No. 1 at a dose of 150 g, the 2nd experimental group– with the additive RusMA No. 2 at the dose of 350 g. The use of experimental mineral additives in feeding lactating cows allowed us to increase their milk productivity and profi tability of production. At the same time, the best eff ectiveness was shown by the additive RusMA No. 2 at the dose of 350 g/head/day. The use of RusMA additives during the experiment period (105 days) allowed to increase the milk productivity of cows in the 1st experimental group by 6,03 % and in the 2nd experimental group by 8,24 %. Taking into account the fat content in milk, this diff erence was 6,31 and 8,53 %, respectively. The energy value of milk from cows of the experimental groups was higher compared to the control group by 2,45 and 1,76 %, respectively. According to the content of dry matter in milk, cows of the 2nd experimental group exceeded the control and 1st experimental group by 0,39 and 0,12 abs.%, respectively. The maximum milk fat content has been observed in the milk of cows of the 1st experimental group by 0,03 and 0,01 abs.% more than in the control and 2nd experimental groups, respectively. In terms of protein content, the cows of the 2nd experimental group signifi cantly exceeded the control group by 0,10 abs.% and the 1st experimental by 0,04 abs.%. The content of milk sugar in the 2nd experimental group was higher than in the control by 0,30 abs.% and compared to the 1st experimental by 0,11 %. Signifi cantly more calcium and phosphorus were contained in the milk of cows of the 2nd experimental group by 4,58 % (Р ≤ 0,001) and 2,86 % (Р ≤ 0,05), compared with the control group. The expenditures of feed in the EFU for the production of 1 kg of milk in animals of the 2nd experimental group was less by 5,13 % than in control cows and by 2,63 % compared to the 1st experimental group. The prime cost of 1 centner of milk was lower in the 2nd experimental group by 3,94 %, in the 1st experimental group by 2,65 % compared to the control group. The level of profi tability of milk production in the 2nd experimental group was higher by 9,0 and 1,0 abs.% in comparison with the control and 1st experimental groups, respectively.

The Impact

Non-alcoholic fatty liver disease (NAFLD) has become of major interest worldwide, it is estimated that more than 20% of the general population suffer from liver steatosis. NAFLD is highly associated with metabolic risk factors like type 2 diabetes mellitus, obesity and dyslipidemia, the patients diagnosed with NAFLD should adopt a high fiber low calorie diet, with reduced saturated fat and carbohydrates content, leading to weight loss and improvement of metabolic profile. Our study is aiming to shape the profile of the patient interested in being informed related to food quality and chemical composition and to evaluate the aspects on the food products label which are important for the customer. Between June 2017 and December 2017, 83 patients diagnosed with NASH were included in the study, representing the study group, while 33 subjects, without metabolic syndrome or digestive diseases, selected from patient list belonging to two general practitioners, constituted the control group. Related to the interest of being informed about the chemical composition and nutritional value of the products bought, the study showed a low interest for the provided information on nutritional value. lack of confidence in the provided information and complexity of the information are understandable, the high number of subject reasoning through lack of immediate clinical benefit is surprising. Among the healthy population the willingness to pay attention to this aspect is extremely low.

Background: Phytonutrients in peach fruits have health promoting antioxidants against various chronic diseases. However, there is no extensive data to show the nutritional values of Local peach cultivars after post-harvest treatments. Objective: Mainly this study was objective to determine the effect of calcium carbide on nutritional value and quality of fruits of Pakistani peach cultivars. Methods: The peach fruits were collected from three different peach orchids of KPK and the fruits were divided into 4 groups while 5th group was collected from local fruit shop. Each experimental group was treated with different concentration of calcium carbide whereas control group was not treated. The peel and pulp samples were oven dried and ground to fine powder separately. The elemental compositions were determined using Particle Induced X-ray emission and Pelletron Tandem Accelerator. Result: Sixteen elements were identified in peach fruits and the elements were Al, P, S, Cl, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Se. In peel, concentration of some elements increased or decreased after treatment with CaC2 while in pulp the conc. of nearly all detected elements was increased in treated samples. We found significantly high amount of heavy metals traces including As, Se, Co, Si, and P in peach fruits treated with CaC2. Interestingly, the presence of trichomes in peach skin prevents the transfer of these heavy metals deep into the pulp which was also verified by the elemental profiling of nectarines. Conclusion: Conclusively, the artificial ripening with CaC2 changed the nutritional value of peach fruits that has higher health risks if consume with the peel. According to our best knowledge, this is the first report that highlights the effects of CaC2 which deteriorate the nutritional value of peach fruits in Pakistan.

Moringa Oleifera Leaves

Moringa oleifera leaves (MOL) have gained great interest as a non-traditional feed ingredient due to their unique nutritional value. Therefore, the objective of the current study was to evaluate the effects of graded dietary supplementation levels with MOL on performance, carcass characteristics, antioxidant capacity, blood biochemical constituents, meat quality, and fatty acids profile of growing rabbits. A total of 120 weaned New Zealand white rabbits (6 weeks old) were randomly allotted into 4 dietary groups with 5 replicates each (n = 6), which were fed for 42 days with a basal diet as control or 3 experimental diets supplemented with 5, 10, or 15 g/kg MOL. The results showed that, compared to the control group, the dietary inclusion of MOL at a level of 10 and 15 g/kg DM linearly increased (p < 0.01) final live weight (2403.3 and 2498.2 vs. 2166.6) and average daily weight gain (36.5 and 35.51 g/d vs. 28.72 g/d), and enhanced feed conversion ratio (2.49 and 2.50 vs. 3.14). The dietary supplementation with MOL linearly increased dressing out percentage, spleen index, intestinal length, and decreased abdominal fat index (p < 0.01). Greater serum levels of total protein and globulin, but lower alanine aminotransferase and aspartate aminotransferase were observed in the MOL-fed rabbits (p < 0.01). Serum levels of total triglycerides, cholesterol, and low-density lipoprotein (p < 0.05) were decreased linearly and quadratically in the MOL groups compared with the control. Glutathione peroxidase activity increased (p < 0.01), whereas malondialdehyde decreased (p < 0.01) linearly and quadratically in both serum and meat, in response to dietary MOL supplementation. Dietary MOL supplementation increased the meat crude protein content but lowered the relative content of ether extract in the meat (p < 0.05). The relative content of the meat n-3 PUFA was increased by about 33.71%, 29.46%, and 24.36% for the MOL0.5%, MOL1%, and MOL1.5% groups compared to control. In conclusion, MOL could be used at a level of 1.5g/kg of the growing rabbits’ diets with beneficial impacts on performance, antioxidant capacity, and the nutritional value of the meat.
