The elaboration of strategies in the field of conservation of animal genetic resources (and not only) had, have and will be based on genetic analysis studies. Without conducting these studies, it is practically impossible to develop management strategies for inbreeding or to develop effective breeding programs. In this paper we present two important indicators of genetic analysis in horse population and not only the reproductive isolation coefficient and the age structure. This parameter has a capital importance in animal breeding because there has a directly influence in animal population evolution. More than that, To be accepted as a population, a herd must fulfill four criteria: reproductive isolation, morphological and physiological differences, environmental requirements and genetic size. The reproductive isolation is the most important criteria for population because only reproductive isolated populations have an own evolution. Regarding the age structure, this parameter has a double importance: for exploitation (influenced directly average age), and on the other hand, for animal breeding (influenced the generation interval and population variability).

The aim of this research was to perform an objective analysis of improvement process for the type of curls on the pelt surface. The research importance is special because in improving this character the desire of the breeder is different. The biological material belonged to the Karakul of Botoșani breed and the entire herd from which the evaluated lambs came is registered in the Genealogical Register of the respective breed. The method applied in assessing the quality of skins was based on the technical norms specified in Section 1.4 and 1.5 of the MADR Order no. 22/20.01.2006. Statistical processing of the data was based on the use of the computer program S.A.V.C. (Statistics Analysis of Variance and Covariance 2003). The assessment of the degree of improvement indicates that the desired curl represented by the shape of long and medium tubes is in an advanced stage as that type increased from 65.11% in 2005 to 66.66% in lambs’ subject to assessments in in 2020. During this time, as a result of the improvement, the proportion of lambs with medium and long tube curls increased by more than 1.5% in the black and greyish variety, the difference being significant for p<0.01.

The purpouse of this paper was to highlight the morpho-productive indicators of Aubrac and Aberdeen Angus cattle breeds exploited in Romania. Data were collected from a number of 40 cattle, following the weaning weight (age of 7 months) and the average daily gain increase of the animals, which benefited from similar exploitation conditions. Also, based on the results obtained, a statistical interpretation was performed. At the age of 7 months, an average body weight of 216.6 kg was observed in Aubrac cattle, with an average daily gain increase of 912 g/day, while in Aberdeen Angus cattle an average body weight of 184.3 kg was observed, the animals recorded an average daily gain increase of 799 g/day. In conclusion, in the case of both breeds of cattle, the satisfactory parameters specific to the breeds of meat were highlighted, but making a comparison we can appreciate that the results observed in the Aubrac breed are superior.

Pumpkin pulp (Curcubita maxima), from organic farming, is an extremely versatile product that can be a basic ingredient in obtaining gluten-free cookies. In this paper, a cookie was obtained using amaranth flour and pumpkin pulp in two forms: fresh and baked. Following the analyses, the aim was to obtain a product with appropriate characteristics. Dough with amaranth flour and pumpkin pulp is characterized by a good ability to bind the dough and retains its shape when pouring. In the sensory analysis of the gluten-free cookies with organic baked pumpkin obtained in the product testing phase, the taste was better appreciated. From the analysis of the average values it is observed that the products obtained with the basic ingredient prepared in advance (baked pumpkin) showed a more intense perception on the attributes of smell, taste and aftertaste.

In this scientific paper, the productive performances of beef cattle belonging to the Aberdeen Angus and Charolaise breeds from 6 farms in Neamț County were analyzed, studying the following indicators: birth weight (kg), body weight (kg), and average daily gain (g) at the age of 200 days (kg), and also 365 days (kg). The data on average values and variability of meat production indices show that the highest performances were 42.33 kg at birth, 246.29 kg and the average daily increase of 1030.71 grams per 200 days, and 433.69 kg with the average daily increase of 1074.33 kg, at the age of 365 days. On the last place was farm 1, which registered an average weight at birth of 30.70 kg, at 200 days this indicator was 188.59 kg, and the average daily gain was 786.20 grams; at 365 days the average weight was 320.84 kg and the average weight was 793.11 kg. Farm 1 raises the Aberdeen Angus breed, and farm 5 raises the Charolaise breed, which has better results due to the constant care of the breeder to improve the genetic material.

In this paper we would like to observe the dynamics of the red blood cell series of chickens, during their growth and development. Research has taken place on two groups made out of 10 chickens: one group (named group 1) containing an industrial hybrid (Cobb 500), and one group (named group 2) containing common breed chicken. The haematological determination has been made at the age of 14, 45 and 75 days. The results obtained showed that at 45 days, the mean corpuscular haemoglobin presented a significant difference (p<0.05), higher with 6.26% than the chicken in the group 2. Regarding the determination made at the age of 75 days, we have found a significant increase (p<0.05) between the two groups regarding: the red blood cells number (with 18.43% higher than the group 2), the haematocrit value (with 7.64% higher than the group 2), the haemoglobin concentration (with 16.6% in favour of the group 2). Regarding the mean corpuscular volume, it presented a significant increase (with 8.64% higher than the group 1). During the experiment, the concentration of mean corpuscular haemoglobin didn’t present any significant changes (p>0.05), the results of this parameter falling within the physiological values.

This study was conducted to evaluate the Fulton condition factor, the hepatosomatic index and the biochemical composition of carp meat (Cyprinus carpio) from aquaculture, reared in earthen ponds (CB), in floating net cages (CV) and in the wild, represented by the Danube River (CD). Significant differences were observed (P<0.05) between the mean values of the Fulton condition factor for fish from the three sources. Regarding the hepatosomatic index and visceral fat, the lowest values were obtained for the CD samples, and the highest in CV. The highest mean value of the protein content (18.55 ± 1.01%) was obtained in the specimens reared earthen ponds (CB), but the values did not differ significantly (P = 0.29) from the CD samples. The differences in lipid content of aquaculture fish meat reared in floating net cages (CV) and in the wild (CD) were statistically significant (P<0.05). In conclusion, fish from aquaculture has a better state of maintenance than that in the wild, fact demonstrated by the values of the Fulton Index. However, wild specimens have a much lower hepatosomatic index and visceral fat values than aquaculture fish.

The chemical composition and nutritional value of food products are determined both by the raw materials from which they come and by the contribution of auxiliary materials. These substances, for the most part, are added in order to improve some properties of the products. Respecting the legislation regarding the allowed limits of additives in food products, it is necessary to pay special attention in order to maintain the safety and health of the population. The generic term pectin includes polygalacturonic acids (acid polysaccharide) whose carboxylic groups are esterified in varying proportions with methyl alcohol and partially neutralized with calcium or magnesium ions. The specific properties of pectic substances, due to which they have uses in the food industry, are the gelling capacity and the stabilizing capacity of emulsions. Also, the gel does not show the phenomenon of syneresis, does not absorb moisture from the external environment and is resistant to sugaring. In our country, pectin is obtained industrially from apple pomace, a by-product resulting from obtaining juices and has multiple uses. The functional properties are largely determined by the degree of methoxylation of polygalacturonic acid, which determine the degree of esterification of this polysaccharic acid.

The research on the influence of age on the reproduction indices in Karakul of Botoșani sheep was carried out by processing the data found in the breeding and calving registers, the lamb register and the existing breeding registers within the S.C.D.C.O.C. Popăuți for the period 2017-2019. Following the research carried out on the influence of the age of Karakul of Botoșani sheep on the reproduction indices, the obtained results indicated a statistically significant link between the age batch of which the sheep belong and the reproductive indices analyzed. The data obtained indicated values of higher reproduction rates in the 52-56 months’ age batch (107.8% fertility rate, 96.4% fecundity rate, 95.5% birth rate and 112.9% prolificacy rate) compared to the results obtained by sheep in the 16-21 months’ age batch (94.6% fertility rate, 90.6% fecundity rate, 89.1% birth rate and 106.1% prolificacy rate).

Ensuring security and resilience in the Romanian dairy and dairy sector is possible only through thought, planning and exercise to absorb, return and then adapt existing production capacity and warehouses to disruptive threats. As it is known, milk is a universal food that is administered both in the first days of birth and throughout life, to children, ado-lescents, the elderly and adults, to people with various diseases but also to the healthy. Ensuring the safety and resili-ence of milk is linked to a highly developed animal husbandry, located as close as possible to large urban agglomera-tions. Investments in this sector are the key to successfully overcoming threats of any kind. The aim of the paper is to analyze the current situation regarding the territorial distribution, by development regions, of the investments made in the milk and dairy products industry, as well as their use, in order to establish areas of interest for possible new invest-ments in this field.
