Seasonal variations in the biochemical composition of rabbit meat
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Tarasenko, Ludmila; Piven, Olha; Khimich, Maria
The results of monitoring of seasonal variations in biochemical composition of rabbit meat, which is implemented on agrofood markets of Odessa region are given in the article. It is established that the rabbit meat which is implemented on spring-summer period is characterized by more pronounced dietary properties. In particular, by 5.6 % less than in the autumn-winter period by the content of proteins, by 36 % lower fat content and by 9.1 % lower ash content. Accordingly the moisture content in it is higher by 5.8 %. In autumn-winter period the rabbit meat which implemented on agrofood markets of Odessa is characterized by higher fat content – 8.6±0.5 %, protein content 17.8±0.5 %, water – 72.5±0.3, ash – 1.1±0.5 %.

Enriching nutritional supplements for bees with biologically active substances of coordinative organic compounds
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Cebotari, Valentina; Buzu, I.; Postolachi, Olga
The purpose of this study was comparative testing, in bee food, of various nutritional supplements enriched with some new organic coordinative compounds of new generation and to reveal the most effective ones for the preparation of nutritional supplements and bee nourishment during periods of poor harvesting in nature. The research was carried out on honey bee families from the Carpathian race at the experimental apiary of the Institute of Zoology of the Academy of Sciences of Moldova. In the experiment, 5 similar batches were formed, with 10 families in each batch. The bee families of the experimental batches were fed for 14 days with nutritional supplements enriched with biologically active substances, a 50% of nutritional blend of sugar syrup and bioactive supplements of coordinative organic compounds (COC).The feeding of bee families with nutritional mixtures was carried out in ratio of 120 ml of the mixture at each interval of populated by bees frame, every 2 days for two consecutive weeks. In batch I (control), bee families were fed only with 50% sugar syrup. For bees of batch II (prototype), the sugar syrup was enriched with the patented bioactive suppliment (MD 850 Z 2015.08.31). For bee families of batches III, IV and V, nutritional supplements enriched with coordinative organic compounds containing rare microelements, referred to as CV-6, CV-8 and CV-22, were used. The research results have shown that some of the coordinative organic compounds tested in bee's feed in the period of poor harvesting in nature, had some influence on reproductive and characteristics of bee families. Thus, in batches II, III and V, compared to the control group, the queen prolificity was higher by 9.9 15.8% (P<0.05 – 0.001), amount of capped brood by 10,0-15,8% (P<0.05 – 0.001) and colony strength by 5,8-6,2% (P<0.001).However, the stimulating effect of reproductive functions is not certain, because the activation of reproductive and developing characters of bee families must inevitably lead to the increasing of the capacity of acumulation of bee products in the nest. Therefore, none of the newly-tested coordinating compounds showed general stimulatory properties, which would result in increased apiculture production, especially honey production.

Physical and chemical indicators, content of micro and macroelements and heavy metals in sunflower honey
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Eremia, N.; Neicovcena, I.; Griţunic, I.
The problems of production of high-quality and safe food products and food raw materials are now quite relevant and widely discussed all over the world. The purpose of this work was to study the physicochemical parameters, the content of micro-, macroelements and the presence of heavy metals in sunflower honey. The content of micro- and macroelements and the presence of toxic elements in sunflower honey were determined by the atomic absorption spectrometry method at the Institute of Chemistry of the ASM. It is revealed that the mass fraction of water in sunflower honey has made 17.12%, a invert sugar – 92.24%, sucrose – 1.35%, Diastase number – 21.49 units to Gotha, oxymethylfurfural – 9.44 mg/kg, the general acidity – 2.26 сm3NaOH solution in (miliequivalent) on 100 g of honey and ash-content – 0.12%. It is revealed that in sunflower honey minerals average Mn – 0.320 mg/kg, Zn – 0.397 mg/kg, Cu – 0.397 mg/kg, Fe – 2.950 mg/kg, Cr – <0.12 mg/kg, Ni – <0.17 mg/kg, and macroelements: Ca2+ – 85.833 mg/kg, Mg2+ – 27.00 mg/kg, K+ – 944.23 mg/kg, Na+ – 23.00 mg/kg, P2O5 – 67.20 mg/kg. It is established that sunflower honey on average contains 1.101 mg / g of amino acids, of which the greatest amount is proline – 27.52%, aspartic acid – 15.44% and glutamic acid – 11.35% of the total amount. It is established that sunflower honey on average contains heavy metals: lead – <0.10 mg/kg, cadmium – <0.01 mg/kg, strontium – <2.3 Bq/kg, zinc – 0.448 mg/kg, copper – 0.318 mg/kg. The mineral structure of honey can depend on the region of origin of melliferous cultures, including on soil and climatic conditions.

Capacities of fatterring of moldovan Karakul lambs
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Evtodienco, Silvia; Maşner, O.; Liuţcanov, P.
To study the fattening capacities of young ovine of Moldovan Karakul breed, five lambs and five female lambs were intensively fattened for 60 days. Were studied body fat indexes and carcasses, were determined the slaughter yield, the bone ratio: meat, the chemical composition of the meat. It has been determined that the average daily increase over a fattening period is 256.8 ± 21.34 g at lambs and 201.6 ± 7.37 g at female lambs. Body indexes such as: lateral corporal format, massiveness, robustness increased at lambs and female lambs respectively by 2.2 and 2.2%, 3.8 and 5.8%, 1.3 and 3.6% respectively. But differences between lots are not veridical (P> 0.1). The yield of killing lambs constituted 49 % of body weight before sacrificing of 38.34 kg. Appraisals of the carcass of lambs allow us to conclude that the jig form and pulp development are at the level of mixed breeds, and the carcass compaction is satisfactory. The bone ratio: meat on the entire carcass constituted 1: 3.39. Analyzing these data, we can say that young ovine of Moldavian Karakul breed in intensive fattening conditions show good fattening capacities.

Comparison of reproductive performance in two old breed pigs breeds in Romania and Bulgaria
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Hoha, Gabriel; Palova, Nadezhda; Casapu, A. Al.; R.P. Arsinte, R. P.; Costăchescu, Elena; Păsărin, Benone
Reproduction characteristics of the two old breed pigs, Mangalita from Romania and East Balkan from Bulgaria were monitored over a three-year period (2015-2018). The reproduction characteristics: age and the weight at the first insemination; age at farrowing; duration of gestation; duration of lactation and prolificity from 20 sows of 2 litters were analyzed and compared. The results recorded for each parameters was: 530.42 vs 450.25 days for age at the first insemination; 112.52 vs. 90.45 kg for weight at the first insemination; 645.1 vs 563.7 days for age at farrowing; 114.7 vs 113.4 days for duration of pregnancy; 52.6 vs 59.2 days for duration of lactation; 5.62 vs 4.95 piglets at first birth; 6.28 vs 6.15 piglets at second birth. The obtained results confirm the data from the literature mentioning that the two breeds are tardiv. We also notice that the Mangalita breed is more tardiv than the East Balkan breed but has a higher weight at first insemination and a higher prolificity.
