“…Adamson & Fisher (1973) determined that the growing young New Zealand rabbits need essential amino acids for increasing their weight. Sychov et al (2018) studied the effect of different levels of methionine in mixed feed on the productivity of growing rabbits, finding that maximal weight gains in conditions of moderate food consumption per unit required mixed feed with 0.41% methionine content. Positive effect of Prebiolakt-Kr on the live weight of rabbits depended on its dose in the diet.…”

Prebiotics are an effective technological element of increasing the productivity of animal husbandry. Currently, prebiotics are being broadly used in cuniculture. Those drugs are a promising means of stimulating growth and development of animals. Prebiotics optimize the metabolic processes and increase the level of nutrient metabolism. Our studies revealed the effect of a prebiotic drug, which contains lactic and succinic acids, aminoacids, vitamins А, В1, В2, В3, Е, on the growth intensity of rabbits. The studies were performed on the young 34 to 160-days-old rabbits of the Hyplus meat hybrid. Animals of the control group were fed ad libitum with full-diet granulated mixed feeds and had free access to water. Animals of the experimental groups were fed feeds of the control-group diet, supplemented by prebiotic additive Prebiolakt-Kr in the doses of 1.5, 2.0, and 2.5 g/kg of the live weight. Every 14 days during the feeding period, the growth intensity of the rabbits was controlled according to individual live weight and average daily increment. Addition of Prebiolakt-Kr to the rabbits’ diet increased the live weight of animals by the end of feeding. We verified and confirmed the positive effect of the prebiotic on the intensity of growth and development of the growing rabbits. According to the absolute increment, the advantage over the rabbits in the control accounted for 7.9–11.9%. Feeding the supplement increased the meat volumes of the rabbits. Also, Prebiolakt-Kr added to the diet caused higher chest girth/diagonal body length index. The animals that were receiving the prebiotic feed supplement used the diet more effectively and had better metabolism of nutrients. The studies revealed a dose-dependent effect of prebiotic on the growth intensity of the rabbits. At the same time, the best stimulating action was displayed by supplementing the diet of the young rabbits by 2.0 and 2.5 g/ind. of Prebiolakt-Kr. The conducted studies have confirmed the benefits of using prebiotic drugs in rabbit husbandry, which improve metabolism and increase body-weight gain.

“…Якщо в 100 г кролятини 168 Ккал, то в 100 г яловичини -274-335 Ккал, баранини -319 Ккал, свинини -389 Ккал. Отже, важливою перевагою кролятини є те, що вона -низькокалорійний продукт (Mishanin & Kuc, 2003;Kalashnik & Omel'chenko, 2004;Plotnikov, 2004;Aleksandrova & Kosova, 2005;Carabaño et al, 2010;Sychov et al, 2018;Kotelevych, 2018).…”

The purpose of the study was to perform a comparative veterinary sanitary examination and vetting the rabbit meat of two breeds, depending on the time of year. The subject of the study was 4-month-old male rabbits raised in the private farm, certified with California matured breeds and a Belgian giant (Flanders). According to the principle of analogues, 4 groups of rabbits of 6 heads were formed (2 each in spring-summer and autumn-winter seasons). Before slaughter was determined – the index of abrasion (girth by shoulder blades, divided by the length of the trunk and multiplied by 100%). Carried out anatomical section of carcasses and determined the output of meat. Then they carried out veterinary-sanitary examination by conventional methods. Biochemical studies of meat samples were performed 12 hours after slaughter at storage at 0 – +2 °C. Chemical analysis of the samples included determination of the water content, total protein, ash and macronutrients: Calcium (oxalate method), Phosphorus (photocolorimetric method by A.Yu. Levitsky in AT Usovich's modification). The results were statistically processed using a MS Excel 2003 computer program using a Student's t-test table. The 4-month-old rabbit meat is of California matured breeds and the Belgian giant (flanders) has high, almost equivalent, organoleptic-tasting characteristics. In terms of taste, tenderness, juiciness, color and aroma, the overall average score in the spring-summer and autumn-winter periods, respectively, was: California maturity – 4.7–4.8, and 4.6–4.7; Belgian Giant (Flanders) – 4.8–5.0 and 4.7–4.8 points. The broth of experimental rabbit meat had a delicate, sophisticated aroma and taste, good transparency and received the following points on a 5-point system: California matured and flanders in spring and summer – 5.0, in autumn and winter – 4.8 points. A comparative analysis of the breed characteristics of the studied rabbit identical samples revealed that the Belgian giant (flanders) has the highest moisture-holding capacity in the spring-summer period. The amount of bound water in the muscles of 4-month-old rabbits of the Flanders breed is slightly higher, so it will be more tender and juicy after cooking. The highest slaughter yield was determined in 4-month-old rabbits of the Belgian giant (flanders) and Californians reared in the spring-summer period, respectively – 56.51 ± 0.2% and 0.75 ± 0.63% (P ≤ 0.001). Among the 2 breeds of 4-month-old rabbits, the largest live and slaughter weights reached the rabbits grown in spring and summer (respectively: Belgian giant – 3375 ± 27.0 g and 1912.03 ± 19.4 g; Californians – 2956.5 ± 6.74 g and 1502.48 ± 5.89 g (P ≤ 0.001) .The amount of nutrients in rabbit depends on the breed and time of year. The lowest protein content is found in the meat of 4-month-old rabbits of the California maturing breed period) – 15.47 ± 0.58%, and the highest – in 4-month flanders (spring-summer period) – 23.02 ± 0.78% (P ≤ 0.05). not, however, more meaty and less calorie meat is rabbit california matured breed, regardless of the time of year.

“…Another relevant way to solve this problem is, in particular, energy optimisation of diets for intensive cultivation of rabbits of highly productive hybrids (Alejandro et al, 2021). The balance of nutrients in the diets of young rabbits, in particular, protein (Sychov et al, 2018). All the described measures and techniques for improving and reducing the cost of technologies for raising young rabbits are effective, since they allow using the genetic potential of animals to the full, maximally ensuring their needs at each stage of ontogenesis (Yakubets & Bochkov, 2018;Birolo et al, 2022).…”

The search for elements of technologies and preparations of natural origin that improve the functioning of the gastrointestinal tract of animals is relevant given that intensive growing technologies involve the use of a significant amount of various kinds of antibiotics that reduce immunity and negatively affect the quality of meat products. Preparations developed on the basis of biologically active substances from essential oils of medicinal and spicy-aromatic plants are promising in this area. The studies used the dietary supplement Activo, recommended for feeding poultry and pigs, created on the basis of essential oils of rosemary, oregano, and thyme. That is why the purpose of the study was to find out the effectiveness and safety of using dietary supplements as an element of intensive rabbit meat production. Research methods – zootechnical, laboratory, statistical. For intensive fattening of young rabbits of the newly created chinchilla type, a mixed feed recipe based on local feed ingredients was developed. It was established that with the addition of Activo to the diet of fattening young rabbits in the amount of 100, 150, and 200 g/t, their productivity at 90 days of age increased, in particular, live weight – by 2.4-5.3%, average daily growth – by 3.5-6.4%, lifetime loin width (meatiness index) by 2.0-2.4%, feed conversion improved by 4.1-5.6%. It is shown that the use of dietary supplements in the amount of 150-200 g/t of mixed feed in the diets of young rabbits with intensive production of rabbit meat reduces direct costs for the production of 1 tonne of rabbit meat by UAH 2,200 and increases the profitability of production by 5%. Thus, the use of a biological additive as an element of intensive fattening of young rabbits helps to improve the lifetime meat content and slaughter yield of young rabbits while reducing the cost of finished feed and increasing its conversion, which leads to a decrease in direct production costs
