<p>It was established that in the progeny of quail obtained from the parent herd, which during the growing period was fed as a source of microelements a complex of glycinates of copper, zinc, manganese, iron and cobalt with microbial β-carotene at a dose corresponding to the physiological requirement during the growing period increased the content of iron in eggs by 22,4 % compared to the control, and by 18,9 % compared to quails fed with chelates of microelements and β-carotene at a dose corresponding to half the daily requirement.</p><p>The concentration of zinc in the quail eggs of this group increased by 16,5 % compared to the control and by 21 % compared to the analogous parameters for the quails of the second experimental group, manganese by 17,4 % and 19 4 %. The increase in the content of iron, zinc and manganese in the quail eggs which feeding complex of glycinate of microelements and β-carotene, at a dose amounting to a daily requirement, indicates their high bioavailability in the digestive apparatus of the bird, their intensive absorption and accumulation in the eggs.</p><p>It was proved that the content of iron, zinc and manganese in the eggs of quail, which feeding a complex of glycinate of microelements and β-carotene at a dose corresponding to half the daily requirement of the bird, was at the control level, which indicates sufficient provision of its body with these elements.</p><p>The data obtained when feeding the complex of chelating compounds of microelements and microbial β-carotene to quails indicate an intensification of the conversion of β-carotene to retinol and an increase in the content of the latter in eggs of the quail by 19,7 %. Feeding quails of the complex of glycinate of microelements in a dose corresponding to their needs contributed to an increase in the dry matter content in the shell of the quail eggs by 2,13 % due to an increase in the ash content by 2,3 %, calcium by 0,83 %, zinc by 30,1% and manganese - by 26,5 %. Feeding quails half the daily requirement of chelates of trace elements contributed to sufficient provision of their body with these elements. The conducted studies testify to the absence of toxic effect of chelating compounds of microelements (glycinates of copper, zinc, manganese, iron and cobalt) on the quail organism, sufficient assimilation from feeds both at doses corresponding to demand, and in doses that make up half of it due to increased bioavailability in the tissues.</p>

ABSTRACT Sweetpotato (Ipomoea batatas) is a root crop grown in many countries. This tuberous root is a source of energy, nutrients, and phytochemicals. In this study, bioactive compounds and physical and physicochemical qualities of sweetpotato genotypes were evaluated. Eight new genotypes of sweetpotato produced by Embrapa Hortaliças (orange-fleshed: MD09026-OF and MD09024-OF; cream-fleshed: MD09011-CF, MD09004-CF, MD10039-CF, and MD10004-CF; yellow-fleshed: MD09017-YF and MD12002-YF) and two cultivars used as controls (Beauregard and Brazlândia Roxa) were evaluated for color, soluble solids, dry matter, phenolic compounds, total carotenoids and β-carotene. Hue angles differed even between those sweetpotatoes with the same flesh color. The orange-fleshed genotypes MD09024-OF, MD09026-OF, and Beauregard, had the lowest L*, showing to be darker than the others. These sweetpotatoes also had the brightest flesh colors with higher C*. The orange-fleshed genotypes MD09026-OF and MD09024-OF were sweeter (10.55oBrix and 9.23oBrix) than Beauregard (5.12oBrix). Brazlândia Roxa had the highest dry matter content (38.05%), followed by the genotypes MD10004-CF, MD09017-YF, MD09026-OF MD10039-CF, and MD09011-CF, which showed similarity, ranging from 32.33% to 29.12%. The highest contents of total carotenoids were found for the orange-fleshed genotypes MD09026-OF (80.06 mg g-1) and MD09024-OF (70.56 mg g-1) and Beauregard (73.12 mg g-1). These same genotypes showed the highest total phenolic compounds (0.815 mg g-1 and 0.686 mg g-1, respectively). MD09026-OF showed the highest content of β-carotene (46.47 mg g-1). MD09026-OF was the most prominent genotype among those evaluated, as it showed the highest total carotenoid, β-carotene, phenolic compounds, and soluble solids content, in addition to a high dry matter content.

SummaryThe effects of the time of sowing on growth and chemical composition of carrots grown from May to November were studied during 3 years.Delaying sowing for 1 or 2 months after the beginning of May resulted in a reduction in the growth of both roots and foliage and gave roots with lower dry-matter content and glucose/fructose ratio but higher amounts of hexoses, total nitrogen and amino nitrogen in root dry matter. Sowing date had no influence on the concentration of sucrose, phosphorus, potassium, calcium and magnesium in root dry matter up to 137 days from sowing. Carotene decreased only after the last sowing. Sucrose concentration of the roots increased throughout the periods studied irrespective of the time of sowing. The longer the growing period the higher was the sucrose concentration. The concentration of hexoses decreased from the first harvest at 70 days to reach a constant level at about 130 days from sowing.The results did not indicate the presence of a well-defined stage of biochemical maturity in the autumn when carrot roots are expected as most suitable for harvest and subsequent long-term storage.

The effects various rates of nitrogen application on accumulation of dry matter and nitrogen in potato (Solanum tuberosum L.) were studied during a short growing period of 140–180 days, at MTT Agrifood Research Finland in 2000–2001. The treatments were 0, 60 and 120 kg N ha-1 and the potato cultivars tested were Van Gogh and Nicola. Four successive harvests were made during the course of the experiment to monitor changes in the accumulation of dry matter and nitrogen over the season. Applications of nitrogen substantially increased haulm dry matter accumulation and to an even greater extent their nitrogen contents. The highest dry matter values were generally registered at 120 kg N ha-1. Dry matter and nitrogen content of haulms started to decline during the later part of season and most nitrogen was relocated to tubers. The results suggest that an application of only 60 kg N ha-1 was sufficient to promote rapid canopy development and there were only small reductions in dry matter and nitrogen accumulation until late in the season when the canopy started to senesce as nitrogen supply diminished. Tuber yield, plant dry matter and nitrogen accumulation at maturity were related to crop nitrogen supply. Although application of the high rate, 120 N kg ha-1, resulted in a significant increase in dry matter accumulation, this was not reflected in the profit because the higher nitrogen application reduced dry matter content of tubers by 2.6% in 2000 and by 1.1% in 2001 relative to the use of 60 kg N ha-1. Apparent fertilizer nitrogen recovery values on a whole plant basis ranged from 53 to 75%. The proportion of fertilizer recovered in tubers clearly declined with increase in nitrogen supply.;

Β Carotene

Roots of orange-fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and crucially important remedy for vitamin A deficiency. The cream or white-fleshed varieties, on the other hand, have a sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. Development of sweet potato genotypes that can combine these two important quality traits is the objective of this breeding work. A diallel experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out and thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for the traits. The average β-carotene content among the progenies was 2.86 (mg/100g.f.w) while the dry matter cttgontent had a mean value of 31.89%. The cross progenies 199024.2 x Excel had the highest beta carotene (14.37mg/100g.f.w) content with the highest dry matter content (40.10%) and are therefore recommended for further evaluation.

Roots of orange fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and important remedy for vitamin A deficiency. The cream or white fleshed varieties on the other hand, have sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. The objectives of this study were to examine the quantitative inheritance of important traits in sweet potato by means of a diallel analysis with a view to estimating the GCA and SCA components of genetic variance, and to determine the associated type of gene action controlling β-carotene content and root dry mass. A diallel crosses experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out. Resultant thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria during the cropping season of 2012 and 2013. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for all the tested traits. The average β-carotene content for the progenies was 2.86 (mg/100 g f.w.) while the dry matter content was 31.89%. The cross combination 199024.2 x Excel recorded the highest beta carotene (14.37 mg/100 g f.w) and dry matter content (40.10%), this candidate is therefore suggested for further evaluation.

A pot and a field experiment were conducted to evaluate the effects of different nitrogen and chloride fertilizer levels on the nitrate content of beetroot. The yield and dry matter content were also determined. Sulphate fertilization was used as a control to chloride fertilization. There was a considerable decrease in the nitrate content of beetroots during the growing season. High nitrogen fertilization caused nitrate accumulation in both experiments. Chloride had a significant decreasing effect on the nitrate accumulation towards the middle of the growing period in the pot experiment. In the field experiment, chloride also decreased nitrate accumulation towards the middle of the growing period, soon after additional application of ammonium nitrate limestone (13.8 % NH4-N; 13.7 % NO3-N). Chloride tends to decrease nitrate accumulation only at an early stage of root development when nitrate is not the only source of nitrogen in the soil. The yield was higher on high nitrogen supply, in the pot experiment also on chloride application. Nitrogen decreased the dry matter content, but chloride had this effect only in the field experiment.

Studies are devoted to the study of the qualitative indicators of the muscle tissue of bulls of brown Swiss breed, depending on the technology of cultivation. It was established that the highest content of dry matter and protein was characterized by the meat of animals of the first experimental group, contained according to the traditional technology using feeding. Their superiority in the dry matter content in the total meat sample of animals of the II and III groups was 0.9 (P<0,001) and 0,45%, respectively, and in the protein content –1.64 (P<0,001) and 0,75% (P<0,001). The ratio of protein / fat was higher in the bulls of the first control group and amounted to 1,09 against 0,95 and 1,03 in the second and third groups. An analysis of the biological usefulness of the protein showed that in the longest back muscle in the content of tryptophan, animals of group I surpass analogs of group II by 11,1 mg%, and in the content of  hydroxyproline are inferior to them by 1,9 mg%. The highest protein-quality index was in bulls of group I, which were grown using feeding, the superiority of which over analogues of group II was 5.85% (P<0,001). Animals of the third experimental group occupied an intermediate position in this indicator and exceeded their peers of group II by 3,77% (P<0,05).

This study aimed at determination of vitamin (A, E, C, β-carotene, and lycopene), phenolic, and flavonoid contents in apricots at different stages of ripening using high-performance liquid chromatography (HPLC). The effect of ripening in terms of phytochemical contents was investigated. Early period apricots showed 2.5 to three times higher level of vitamins (A, E, C, and β-carotene, and lycopene) in all types of apricots than others (P < 0.05). Early-ripened cultivar, Boccuia, showed the highest level of vitamins, although a higher level of vitamin C was measured in late-ripened cultivar Levent (P < 0.05). No lycopenes were determined in late-period apricots in contrary to early- and middle-period apricots. Levels of phenolics and flavonoids were measured in all types (3-B-Q-D, procyanidin B1, B2, B3, caffeic acid, gallic acid, p-coumaric acid, epigallocatechine, catechine, epictechine, chlorogenic acid, ferrulic acid, and routine) and statistical deviation of all types was noted (P < 0.05). Among all, the cultivar Özal showed the highest level of chlorogenic acid (45,843.00 μg·g−1 dry matter) in all ripening periods, where middle-ripened cultivar Adilcevaz showed the lowest level of p-coumaric acid (7.93 μg·g−1 dry matter content base).

A complex of mammological studies was carried out in experimental farms of the Vladimir region. Lactating cows underwent an express diagnosis of the health of the udder with the California mastitis test, and based on the result obtained, three groups of animals were formed, 20 animals each. The animals of the first group had a questionable reaction to the California express method; animals the second - weakly positive; the third group included blood with negative reaction to tests (control). In studies of milk from cows with suspected udder inflammation, a decrease in dry matter content and a change in the quantitative ratio between the constituents of milk were found. The dry matter content in the milk of the cows of the 1st experimental group exceeded this indicator in the milk of the 2nd group of cows by 7.6%; and lagged behind the control by 12.8%. When milk from sick cows was heated, some of the whey proteins were destabilized. The titratable acidity of the milk of the cows of the 1st experimental group was within the limits stipulated by GOST for the prepared milk, while in the cows of the 2nd group it was reduced to 13.22 ± 0.16 ° T, which indicates the onset of the inflammatory process in the mammary gland. When carrying out echographic visualization of the excretory system of the udder of cows, the following features were revealed: with a large volume of the milk cistern, the main type of branching of the excretory system was observed; with medium and small - mixed type; and with mild - loose As a result of the experiment, it can be concluded that animals with a weakly positive reaction to the California Mastitis Test are less productive and they receive milk of lower quality, which is practically not suitable for further use for technological purposes. However, according to the current Technical Regulations, this milk can correspond to the first or second grade.
