Results of meat yield produced from guinea fowl slaughtered at different ages
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Roşca, D.C.; Usturoi, Marius-Giorgi
Exploitation of Guinea fowl in intensive farming has broad development prospects due to the increasing demand of consumers for the meat and eggs yielded from this species, but also for the very valuable biological features. In the present paper we intend to analyze the quantitative production of meat obtained from guinea-fowl slaughtered at different ages. The studied biological material was represented by 50 heads of gray Guinea fowl (Numida Meleagris), reared by species-specific technology. The actual determinations were performed on 31 individuals (10 males and 21 females) who were slaughtered at the age of 77 and 91 days, respectively. The target indicators were body weight at slaughter time, fresh and maturated carcass weight, weight and the proportion of cut parts in whole carcass formation, determined in accordance with the poultry research methodology. The data were statistically processed using the Anova (Analysis of variance) program. At the time of slaughter at the age of 77 days, body weight of Guinea fowl was between 1545.04g and 2250.12g; at the age of 91 days, body weight oscillated between a minimum of 2100.35g and a maximum of 2555.05g, The growth of guinea-pigs can be seen as a profitable business with the use of modern technologies, but also of good quality biological material.

The growing and amelioration of karakul sheep in the Republic of Moldova
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Buzu, I.
The purpose of this paper was to compare the historiography and evolution of the amelioration of sheep races Ţuşca, Karakul, to evaluate the efficiency of their crossing at the different stages of socio economic development of the Republic of Moldova. The research was carried out on the basis of the analysis of the bibliographic sources of some authors from different historical periods of society development, as well as on own scientific researches in the long term (1989-2018). It was found that according to the historical traditions of the population in the northern and central areas of the Republic of Moldova, the locals grew local Ţuşca sheep breed, with mixed milk-wool-furskin production. The idea of improving the furskin qualities of lambs of the local Tusca race by crossing with Asian Karakul race appeared starting with 1884 in Basarabia, due to the excessively high furskin of Karakul pears worldwide and locally, compared to other ovine products (milk, meat, wool). The periodic imports from Turkestan of pure-blooded Karakul sheep at the end of the 19th century - the beginning of the 20th century, as well as in the interwar period, led to the establishment in Basarabia of nurseries of the pure Asian Karakul as pure race, as well as the first sporadic cross-breeding works with the local Țușca race for the improvement of the furskin qualities of lambs. After II World War, imports from Central Asia of Karakul sheep were systematically carried out every year in increasing quantities and the crosses of the local Țușca with the pure Karakul race had a mass character and were carried out by the absorption method. The mass crossbreeding of local ewes (Ț x K) with the Asian Karakul rams has led to some amelioration the lamb furskin qualities and, at the same time, to the reduction of sheep resistance to environmental hazards, a significant decrease in viability, body mass and milk production. From 1979 to 1980, the scientific researchers of the former Moldavian Branch of IUCŞK (Samarkand) applied a new approach to the process of selection of local sheep (ŢxK) after an integral complex of characters (furskin quality, body mass and production milk), elaborating the oviculture development strategy, a series of instructions and programs for genetic amelioration of sheep Karakul, methodical and technological recommendations for their selection under market economy conditions. As a result, in Republic of Moldova was created a new type of Moldavian Karakul sheep, adapted to the local environment conditions with increased production skills for furskin-milk-meat has been created and approved, which provides on average: the share of I sort furskins 65 -70%, body weight of youth at 6 months 35-40 kg , 55-57 kg in adult ewes, 90-95 kg in breeding rams, ewes milk production for the entire lactation 70-75 kg.

Studies regarding the influence of rearing system for laying hens (loft vs. battery) on quality of eggs
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Spridon, C.; Druc, Paula-Viorela; Gavrilescu, Carmen; Usturoi, Marius-Giorgi
Research was focused on quality of eggs provided by ISA Brown hybrid exploited in two different systems: Natura Nova Twin loft; Eurovent battery. Eggs were gathered at for different ages of birds (20, 31, 40 and 60 weeks). Abnormal morphological eggs were into a mean rate of 1.43% at hens reared in battery and of 1.36% at the ones from loft. Mean weight of eggs was 58.99 g at the hens from battery and 59.23 g at the ones from loft, format index was 77.97% for hens from battery and 78.42% at the ones from loft. Mean thickness of mineral shell was 0.363 mm for the eggs of the hens reared in battery and 0.381 mm at the ones from loft, shell breaking resistance was 0.329 kgf/cm2 respectively 0.332 kgf/cm2. Regarding eggs’ structure, at the ones gathered from the hens in loft was founded a higher rate of yolk (30.33-32.99%) and shell (10.17-11.82%), while at eggs of the hens from battery, albumen was predominant (56.90-57.97%). Albumen index was at mean levels of 0.211 (rearing in battery) and 0.221 (rearing in loft), yolk index was 0.455 respectively 0.472, and Haugh index was, in average, of 96.09 HU (battery) and 96.66 HU (loft). Yolk colour was of 9.88 colour units at eggs provided by rearing in battery and 9.99 units at the ones from loft. The conclusion of our study was that loft rearing system offers optimal conditions to laying hens for evolution of metabolic processes specific for egg formation, materialized in superior qualitative and physical metabolic indexes.

Research concerning the exploitation technologies and production of bovine meat in Romania's east cross-border area
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Maciuc, Vasile; Korlyuk, S.; Tarasenko, Ludmila; Nistor, Cătălin-Emilian
Aim of the paper was to analyze the exploitation technologies and the results obtained in the production of bovine meat. The research was carried out during 2013-2015 in the cross-border area of Romania, Ukraine and the Republic of Moldova. The meat production in Romania is at the level of 206 thousand tons of live weight at slaughter in 2016, 6 thousand tons more than in 2015 when meat production was 200 thousand tons live weight at slaughter. Compared to 2013, we see a decline in bovine meat production, which may be due to market fluctuations that occur both at national and on the Community market. In terms of cattle slaughter in specialized units, the number of slaughtered heads has decreased, but the average carcasses weight has increased (from 280 Kg to 327 Kg). For the Odessa region, the production of meat in 2013 was 32203 kg and in 2012, 35233 kg with 3030 kg less or 8.6%. The average daily gain was 402 g per day in 2013, up with 23 grams more than in 2012. Meat production (live weight) in the Republic of Moldova in all farms increased by 4.5% in 2009, and in 2010 it is decreasing, reaching in 2012 at 15.8 thousand tons, less by 14.2%, compared to 2009. Having in view of the cross-border study, the following measures are necessary to make farms more profitable: increasing the cutting weight which will result in high meat yields in the carcass; integration of cattle breeding activity into U.E. standards and regulations; to promote the activity of genetic improving the cattle population in order to increase and improve meat production; financial support for the organization of farms in associations, in order to represent their interests in relation to the suppliers of inputs and beneficiary of the made products; securing own revenues by capitalizing on export goods; ensuring the necessary conditions for exteriorization of the animal's production potential; stimulating the growth of animals in hill and mountain areas with opportunities for exploiting beef cattle.

Estimation of the heterosis effect for the production of meat in goats
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Pascal, Constantin; Nechifor, I.; Cristian, C.; Florea, M.; Valusescu, Daniela
In the current research, aspects that may influence meat production were analyzed, and in order to obtain results close to reality, the research team considered the elimination of some factors of influence that could distort the way of expressing the characters under evaluation. Therefore, estimating the heterosis effect for meat production was based on a well-developed plan in which experimental treatments were similar. For the accuracy of the data, the fattened goat comes from the same calving season and, during the lactation, period, the young goat was kept together with the goat mothers in common breeding chairs and the weaning was done at the age of 80 days. When constituting batches for fattening, weight was also taken into account, being accepted only individuals with similar body development, the admitted differences being of ±2 kg. The analysis of the heterosis effect pattern for the characters referring to the cut portions in the casing, respectively for the neck and back, the head of the chest, the crotch and for the jig, the heterosis effect determined has higher values at the Anglonubiana half breed and the statistical significance for the proportion of the jig is significant for the statistical threshold of more than 5%. On the basis of these data, it may be recommended that when the production of goat meat is prioritized, it can be used the industrial crossbreeding for the Anglonubiana male goats.
