The goal of this paper was to highliht the use of some algal species in bread fortification. Using data fom scientific literature, two directions were followed: highlighting the role and nutritional value of algae species; the analisys of potential benefits of the bread fortification. Food enrichment consists in the incorporation of food resources, rich in proteins, desired lipids or micronutrients, in a widely consumed and accessible basic food, to improve its nutritional balance. Bread, which is a high carbohydrate food, is habitually traditionally consumed with almost all foods in our country. White bread contains 35-43% moisture, 6-16% proteins, 45-58% carbohydrates, 0.5-1.5% lipids, 0.5-1.5% ash, and 1-1.5% salt, and 100 gram bread has approximately 250-270 calories. Nutritional value of the traditional bread types are increased by adding them foods additives such as walnuts, grapes, and sunflower seeds. Also, the micro and macroalgas are valuable sources for the bread fortification. The algal biomass shows promising qualities as a novel source of protein for bread. Compared to conventional bread, the average nutritive quality of most of the breads enriched with algae was superior, or at least equal. According with the analized data all the enriched breads presented a good global acceptability, even though the lower levels of the algae contents were more appreciated for color.

The paper presents the influence of the raw material (matrix) in the homogeneity and stability assessment of two batches of candidate reference material MR001F - IBA produced at an interval of 30 days and evaluated for three months. The statistical interpretation of the moisture content of wheat flour type 650 indicates the need to carry out feasibility studies for each batch made under the same processing conditions. The feasibility study carried out followed the implementation of the recommendations from the ISO 35: 2017 guide regarding the risk in the stability of the reference material produced in successive batches. Stability has been assessed according to section 8.3.2.1 - Classical stability studies - Repeatability conditions of measurement from the ISO 35:2017 guide.

The aim of this research was to identify the impact of hypodynamics on the particularities of the interior of Karakul sheep, raised in different conditions of maintenance. The research was conducted on three similar batches of Karakul sheep, 150 heads in each batch. They were raised in different conditions, from the age of 3 months to 32 months. During the winter (December-March), the sheep from all batches were traditionally kept in stables in paddocks and fed with a mixture of chopped fodder, according to the zootechnical norms. During the summer (April-November), the sheep from Batch I (control) were kept grazing with daily movement at a distance of up to 10-15 km. The experimental Batch II sheep were maintained in the summer at the stable with daily active walking at a distance of 2-3 km. The sheep from Batch III were maintained throughout the experiment, at the stable under hypodynamic conditions. Sheep from batches II and III during the summer were fed green mangers, according to the zootechnical norms. It was found that in sheep in Batches III and II, the degree of oxygen saturation of arterial blood was significantly lower, compared to that of sheep in Batch I, by 7.4 and 2.8% (td = 5, 81 and 2.89; P <0.001 and P <0.01). At the same time, in sheep in Batches III and II, the degree of oxygen saturation of venous blood was significantly higher, compared to that of sheep in control Batch I, with 64.6 and 29.2% (td = 5.52 and 2.35; P <0.001 and P <0.05). In Batches III and II sheep, the level of oxygen utilization by body tissues was significantly lower compared to that of Batch I sheep, respectively by 40.1 and 17.4% (td = 7.43 and 3.06; P <0.001 and P <0.01). Sheep in Batch III significantly outnumbered their contemporaries in Batch I by 1.04 kg or 41.1% (td = 9.15; P <0.001) of gross internal fat deposited in the body after slaughter, by 1.80 kg or 7.5% (td = 2.61; P <0.05), after cutting yield, by 3.17 or 6.6% (td = 2.82; P <0.05) and after mass of the omasum, with 28 g or 29.2% (td = 5.65; P <0.01). At the same time, the sheep from Batches II and III, yielded significantly to the contemporaries from Batch I, after the development of internal organs, such as: liver, heart, lungs, kidneys, stomach, rumen, abomination and small intestine, by 14.4-37.9% (P <0.05 - 0.01). In the Batch III sheep, there was an obvious tendency to decrease, compared to the control Batch, the quality of the furskins, expressed by the weight of the furskins of Sort I, by 12.9% (td = 1.88; P <0.1).

Cattle are the most widespread category of domestic animals, with a special importance for the economy and agriculture of any country. Cattle produces 96% of the world's milk consumption, over 30% of meat and 90% of leather production. An important category in cattle is the "dairy cow", considered a living plant that transforms feed into animal products with a special nutritional value for human consumption. It is also an increasingly powerful "animal machinery", whose efficiency and productivity depend on its genetic background, diet and management. The present study showed that the level of protein in food can influence milk production.

The paper presents the influence of temperature on the stability of the reference material, wheat flour matrix, MR001F-IBA. Experimentally, the stability of the candidate reference material units MR001F-IBA were evaluated in different storage conditions using a temperature of 4°C and, respectively, a range between 25-30°C degrees. The 3 batches of candidate reference material evaluated were produced according to the requirements of the ISO 17034: 2017 “General requirements for the competence of reference material producers”. The results obtained by testing the MR001F-IBA reference material units according to the ISO 2171: 2007 standard indicate that there are no differences in the ash content in the analysed samples. The results are interpreted statistically according to the recommendations from the ISO 35: 2017 guide, these substantiating the information necessary for the MR001F - IBA certification. The purpose of the paper was to establish the conditions in storage, transport of MR001F-IBA for ash content.

The aim of the research undertaken was to highlight that emission reductions can be made available to producers in the steer farming sector and the adoption of current best practices and technologies for the rearing and health of animals, feed rations can be a tool that would help the dragline sector reduce greenhouse gases, and was realized on the Moara Domneasca farm on a flock of 29 dairy cows at different stages of Montbeliarde’s lactation between January 2021 and September 2021. Daily milk production was established per lactation cycle, within the lactation cycle of 3 distinct stages and the establishment of two seasons, summer and winter. The influence of feed strategies applied on milk production, manure chemical composition and CH₄ and CO₂ emissions were analyzed. The milk production of cows was not influenced by the addition of vegetable oils, ranging between 22.04 l / head in the ascending phase of lactation, 19.86-20.96 l / head in the plateau phase and 19.45 l / head in the descending phase of lactation. The methane emission from enteric fermentation shows the highest values for variants 4 and 3, when 0.2 l/head/day of rapeseed oil were administered in each variant, and in version 4, 0.1 l/head/day of sunflower oil was also administered (methane emissions are 1.41 kg CH₄/year and 1.39 kg CH₄/year, respectively). The lowest emissions are recorded for nutrition variant 5 (in which equal doses, sunflower oil and rapeseed oil were administered: 0.1 l l/head/day). Also, the trend of CO₂ equivalent emissions closely follows the line of CH₄ emissions from enteric fermentation, being directly dependent.

The pikeperch (Sander lucioperca, L. - 1758) is one of the freshwater species recently introduced in intensive aquaculture. In the last decade there have been made great efforts in the direction of developing the intensive culture of this species. The population density is a very important technological parameter for fish growth, in all stages of development and is specific to the species, age and technology applied, the most difficult to achieve and with the most significant losses being recorded in the post-embryonic period. Therefore, the growth of the pikepech in the post-embryonic period was experienced in “Evos” type fiberglass pools, in three experimental versions, with three different population densities like: V1 - 1000 ex./basin, V2 - 2000 ex./basin and V3 - 3000 ex./basin. There were two critical moments in the post-embryonic development period: the first was at the beginning of exogenous feeding time, and the second during the swelling of the gas bladder. The experiments were performed at S.C.D.P Nucet, in triplicate, during three growing seasons (2018, 2019 and 2020). The best results were obtained in V1 version, where the survival rate was 69.5% in 2020, the average individual growth rate in 2019 was 1.555 g/ex., and the Fulton coefficient was between 0.93 and 1.13.
