Dagestan is the leading Republic of Russia in terms of the number of sheep and sheep breeding products. The zoned target sheep breed in Dagestan is the Dagestan mountain breed. However, this breed produces thin but non-merino wool. Developing the Merino sheep breed suitable for mountain breeding is an urgent problem. The new Merino sheep breed was developed for the foothill zone of Dagestan, where summer Alpine and winter low-lying pastures are located at a distance of no more than 150 km from each other, and summer Alpine pastures are located at an altitude of up to 3000 meters above sea level. The research and stock breeding work was carried out at the farm production enterprise “Krasniy Oktyabr’”, the Kazbek district, in the period between 2005 and 2019. The work resulted in the development of the Arthlukh Merino sheep breed. (Patent for selection achievement No. 10112 “State Commission of the Russian Federation for Selection Achievement Tests and Protection”). The breed was developed by crossing the Stavropol sheep rams with the Dagestan mountain sheep, with the subsequent improvement of crossbreeds by the Manych Merino breed. A distinctive feature of the new Merino breed from the basic herdmates of the Dagestan Mountain breed is the high live weight, which is 15.3–16.5% higher in different sex and age groups. Besides, the amount of washed wool shorn is 16.2–26.0% higher. The ewes’ wool fineness is 22.9 microns (19.4–23.0) – 64 qualities. That of adult rams amounts to 23.3 microns (19.9–23.3) and has 60 qualities. The difference of the wool fineness on the side and thigh does not exceed one quality. The coat length on the side of ewes is not less than 9.0 cm, rams – 9.5 cm, gimmers (young ewes) – 9.5 cm and replacement rams – 10.0 cm. The wool strength is 7.0 cN/Tex. The belly wool cover is good. The suint is stable, of a white and light cream color. The average yield of washed wool excluding the lowest grades is 64%. The fertility of ewes ranged from 125% to 135%.

The Republic

The planned breed for breeding in the Republic of Dagestan is Dagestan mountain breed. However, from sheep of this breed fine merino wool is not obtained, and the breeding of special merino breed for mountain and transhumant breeding system is an urgent problem. The purpose of the research was to characterize the main breeding traits in different sex and age groups of sheep of the new breed Artlukhsky merino, such as live weight, wool shearing and its qualitative parameters. Artlukhsky merino breed was bred by using Dagestan mountain breed on the ewes at the beginning stage of the rams of Stavropol breed, and at the final stage – Manych merino breed. The research of the parameters of the breeding traits has been made on elite and class I animals in the breeding farm of the APC “Krasny Oktyabr” in the Kazbekovsky area in the Republic of Dagestan. The live weight of sheep of different sex and age groups of the tested breed was 45–97 kg. The average fineness of wool fibers in adult rams was 23,3 microns (60 quality), in ewes – 22,9 microns (64 quality), in rams aged 12 months – 22,1 microns and young ewes – 20,9 microns (64 quality). The difference in the fineness of the wool on the side and thigh did not exceed one quality. The length of the wool fibers on the side on average in adult rams was at least 9,9 cm, in ewes – 9,4 cm, in young ewes – 10,2 cm and young rams – 10,4 cm. The yield of washed wool in the herd was at the level of 64 %, the fertility of ewes was 125 to 135 %. Thus, the indicators of the main selected traits in sheep of the new breed Artlukhsky merino are at the level of the best domestic breeds, such as Volgograd and Vyatka.

The serum protein-bound iodine concentration in the blood of beef steers varied between animals and was not correlated with the daily gain during the fattening period. The data, however, are insufficient to arrive at a definite conclusion.The average erythrocyte counts of the blood were 7·86 (range: 5·89–8·75), 8·59 (range: 6·55–10·15), and 8·54 (range: 5·23–9·62) million per mm.3 for steers of 14, 26 and 38 months of age. The difference between the counts of the yearlings and that of the other age groups was statistically significant. The red cell fraction increased with live weight over the range 700–1230 lb. Although a significant (P < 0·01) correlation was found between the number of erythrocytes in the blood and the daily gain of the steers, the erythrocyte count cannot be employed to predict the possible gaining ability of single beef animals.The haemoglobin content of the blood was found to be 14·02 (range: 9·8–17·4) in the case of the yearlings, 14·68 (range: 11·8–18·5)and 14·61 (range: 7·95–16·85) g./100 ml. blood in the case of the 2-year-olds and 3-year-olds respectively. These differences between age groups were not significant.A correlation of 0·31 was found between the haemoglobin content and live weight of steers within the weight range of 600–1230 lb. The data suggest that for every 100% increase in weight, the haemoglobin in the blood increased by 17%. No correlation was found between the haemoglobin content and the rate of gain of the steers.

Here is presented the analysis of sheep meat productivity of the Russian meat Merino breed  and the effectiveness of selection for large size of animals, the severity of meat forms, and their higher precocity is shown. The selection differential for live weight in animals of different gender and age groups was determined, which is 5.0-26.0 kg, or 10.0-32.5%. The number of Russian meat Merino sheep (n=1045) is characterized by the severity of meat forms (T5) and has a desirable type of physique, exterior and meat productivity (100%), which confirms the consolidation of the herd on this basis. It was found that the genetic resources of the herd allow young sheep to receive a high average daily increase in live weight (170.4 g) from birth to 4.5 months. It is experimentally proved that the offspring of the PMM breed with intensive feeding is characterized by a higher growth energy. It is noted that the descendants of meat Merino have a large carcass mass of 12.4%, a slaughter yield of 2.2 abs. percent and a meat content coefficient of 21.3%, compared to the Stavropol sheep breed of wool productivity. Experimental data confirm that the sheep’s meat of the Russian meat Merino breed is " marbled, has high quality and consumer properties.

The studies were conducted from 2012 up to 2016 years  in the Agricultural Production and Consumption Cooperative for the production of seeds "Elita-Alexanderfield" of the Cahul district and at  theTechnological  Experimental Station "Maximovka" in the District AneniiNoi on a number of sheep of different sex-age groups of the Moldavian type of Tsigay sheep .. Growth and development of lambs were studied  with the way of individual weighing of young animals at  weaning  at 3-3.5 month and 6-7 month  in accordance with generally accepted methods and on the basis of "Recommendations on the technology of production of sheep breeding in the Republic of Moldova". The  class assessment of young animals was carried  at 12-13 months of age in accordance with the "Instruction forbonitization of sheep semitone-root breeds with elements of breeding work." Also were taken into account individual cuttings and live weight of adult livestock before the breeding campaign, productive indicators of breeding sheep selected in the selection grouprams, ewes, repair lambs and (she) lambs. During theinvestigated  periodin both farmshugged6,579 heads of ewes  and were obtained7010 lambs. Fecundity of ewes was 106.6%, in the number of twinswere born 862 lambs or 12.3%. At the age of 3 - 3,5 months were evaluated 1743 of  lambs and 2517 of (she)lambs. The lambs had a living weight of 24.45 kg with a wool length of 6.18 cm andat the(she) lambs, respectively, 21.85 kg and 5.99 cm. At lambs  , the live weight was with 2.6 kg higher and the wool length 0.19 cm in relation to(she) lambs (P ≤ 0.001). From theevaluated 1743lambs, to the 3-5 points with a high energy of growth are attributed 697 (39.9%) of the heads  and for (she)  lambs  1729, which is 68.7%. The live weight of sheep in the range from 25.94 kg to 31.38 kg and at (she) lambs 21.51 - 26.29 kg. Young animals that received 3-5 points are recommended tobe  grown for herd repair andimplementation of other peasant and  farm households. When assessing at 12-13 months of age for lambs to classelitebelong  402 heads or 96.9%. The live weight was 49.05 kg, the wool cut was 4, 84 kg with the length of the staple 12.66 cm. The percentage of elite(she) lambs was lower in comparison with the lambs and  was45.6%, and the productivity index was 40.59 kg, 4.09 kg and 12.5 cm. When assessing the productivity of the sheep of the main flock for wool cut and live weight, it was revealed that the live weight of the rams in theinvestigated  two farms is the same at 70.97 and 70.91 kg. According to the ewes, the living mass in theTechnological Experimental Station "Maximovka" is 52.45 ± 0.22 kg, and in the Agricultural Production and Consumption Cooperative for the production of seeds "Elita-Alexanderfield" 53.22 ± 0.08, which is higher by 0.77 kg (P ≤ 0.001).

Eye Movements During Reading

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.

The Difference

Though there are exhaustive data about participation, performance trends, and sex differences in performance in different running disciplines and races, no study has analyzed these trends in stair climbing and tower running. The aim of the present study was therefore to investigate these trends in tower running. The data, consisting of 28,203 observations from 24,007 climbers between 2014 and 2019, were analyzed. The effects of sex and age, together with the tower characteristics (i.e., stairs and floors), were examined through a multivariable statistical model with random effects on intercept, at climber’s level, accounting for repeated measurements. Men were faster than women in each age group (p < 0.001 for ages ≤69 years, p = 0.003 for ages > 69 years), and the difference in performance stayed around 0.20 km/h, with a minimum of 0.17 at the oldest age. However, women were able to outperform men in specific situations: (i) in smaller buildings (<600 stairs), for ages between 30 and 59 years and >69 years; (ii) in higher buildings (>2200 stairs), for age groups <20 years and 60–69 years; and (iii) in buildings with 1600–2200 stairs, for ages >69 years. In summary, men were faster than women in this specific running discipline; however, women were able to outperform men in very specific situations (i.e., specific age groups and specific numbers of stairs).
