ABSTRACT: This study aimed to evaluate weight and morphometric growth of the products of the complete diallel cross-breeding between pacu and tambaqui during the period from the end of spring to the beginning of winter. Was used 400 pacu, tambaqui, tambacu and paqui. 20 fish from each group were collected, weighed and submitted to morphometric evaluation every 28 days. The Logistic function adjusted better to describe the growth in body weight and the morphometric measures for age on all the genetic groups. The studied groups presented similar behavior of growth for body weight and morphometric measures. There were significant differences between the genetic groups regarding parameters A (asymptotic value) and B (integration constant) for body weight and for all the morphometric measures evaluated. For the parameter K (maturity rate), there were significant difference between groups for body weight, head length and body height. The groups possibly were affected the decrease of temperature. The Tambacu was superior to the Paqui in all the variables evaluated for the parameter A, and was also superior to the pure breed, except for head length and body width.

The aim of the study was to determine and compare the reactive agility league players and players of regional competitions and its changes due to sport-specific warm-up. The research sample consisted of 43 players, who were divided into two groups. First group consisted of 22 players from teams playing in the national league competitions (24.3 ± 5.6 years, body height 179.4 ± 8 cm, body weight 74.8 ± 10.4 kg), the second group of 21 players playing lower regional competitions (26.7 ± 5.64 years, body height 180.2 ± 7.7 cm, body weight 77.8 ± 10.5 kg). We used Fitro agility test modified for table tennis before and after warm-up. For data analysis was used two-way ANOVA with repeated measures. When comparing reactive agility, we found significant difference before and after the sport-specific warm-up for group of league players (885.94 ± 122.69 ms before the warm-up, 842.80 ± 119.48 ms after the warm-up, an improvement of 4.87 %, p <0.0004) and also for the group of players from lower competitions (932.96 ± 114.78ms before the warm-up, 871.90 ± 119.68 ms after the warm-up, an improvement of 6.54 %, p < 0.0002). Although league players achieved better results, the difference between the groups was found not significant. The nonsignificant statistic values for interaction indicates, that league players did not respond to the sport-specific warm-up differently than players from lower competitions. Sport-specific warm-up is important for improving the reactive agility and therefore should not be underestimated.

Abstract. Yaemkong S, Jaipong P, Kotham P, Ngoc TN. 2019. Phenotypic and morphometric characteristics of Bangkaew dog in Phitsanulok Province, Thailand. Biodiversitas 20: 2877-2882. A research study was conducted to analyze phenotypic and morphometric characteristics of Bangkaew dogs in Mueang, Phromphirum, and Bangrakam districts, Phitsanulok Province, Thailand. In total, 54 Bangkaew dogs were randomly sampled by purposive sampling from 20 farmers between November 2018 and March 2019. The data consisted of nine phenotypic characteristics that were recorded visually and five morphometric characteristics that were obtained by using descriptive statistics and analysis of ANOVA to compare difference among means and correlation coefficients. Majority of the standard identities of Bangkaew dogs were according to the breed such as the guard coat around the face (100.00%), the guard coat around the neck or the chest coat (100.00%), the coat of belly (100.00%), the guard coat behind ears (100.00%), the lion’s leg shape (100.00%), the long coat from hip to the upper thigh (100.00%), and the plume tail (100.00%), except for the guard coat from the ruff around the shoulder (98.15%). Moreover, the coat of hair of Bangkaew dogs in this study was white-brown color (55.31%), followed by white-gray color (23.92%), white-black color (10.78%), brown color (6.44%), gray color (2.11%), and black color (1.44%), respectively. Least square means of males morphometric characteristics was significantly (p<0.05) greater than female body weight (21.44 ± 3.33 kg vs. 19.04 ± 3.01 kg), body height (49.52 ± 4.09 cm vs. 46.21 ± 5.30 cm) and leg length (38.64 ± 8.88 cm vs. 34.31 ± 5.75 cm), except for body width (19.48 ± 5.82 cm vs. 17.76 ± 4.24 cm; p>0.05), and for body length of females (55.76 ± 9.37 cm vs. 55.00 ± 7.18 cm; p>0.05) was superior to males of Bangkaew dogs. The correlations among morphometric characteristics such as body width vs. leg length, body length vs. body height, body weight vs. body height, body weight vs. body length, and body height vs. leg length, were 0.64, 0.56, 0.52, 0.34, and 0.33, respectively. These results implied that in order to conserve standard identities and improve morphometric characteristics, their typical characteristics such as structure, coat of hair and body size required by raisers should be considered in the breeding selection and mating system.

The purpose of this research is to compare some coordinative abilities in terms of team and individual sports. A total of 112 athletes were included in the research, of which 60 athletes were from individual sports (Athletics=20, Archery=20, Karate=20) with mean age of 15.02±0.813 years, mean body height of 1.64±0.88 meters and mean body weight of 54.80±11.196 kilograms and 52 athletes were from team sports (Football Player=32, Basketball Player=20) with mean age of 14.98±0.727 years, mean body height of 1.67±0.90 meters and mean body weight of 58.10±9.770 kilograms. Numbered medicine ball run test, backward medicine ball throw test and sprint at the given rhythm test were used to evaluate performances related to coordinative abilities. When our results are examined, it is seen that averages of the participants in team sports category in terms of rhythm, orientation and differentiation abilities are at better level than averages of the participants in individual sports category. It has been seen that individuals in team sports category have significantly better performance than athletes in individual sports in terms of their orientation and differentiation abilities. On the other hand, no significant difference was found for rhythm ability. Consequently, results of the study confirm our pre-research expectations. On the other hand, when literature is examined, it is significant that results obtained from other studies examining coordinative abilities of the athletes in individual sports and team sports categories are similar to our results. It has been seen in the studies in the literature that some results are not similar. It can be thought that different results are caused by age differences and differences in types and branches of sports in which athletes participate.

AbstractThe experiment was conducted at the level of a pilot farm located in eastern Algeria under a humid bioclimatic stage, during two successive crop years. The study focused on a F1 generation of barley (Hordeum vulgare L.) consisting of twelve hybrids from a complete diallel cross between the two locals varieties (Saida and Tichedrett) and two other introduced varieties (Nadawa and Fouara). The aim was to determine the value of parental genotypes as genitors and to analyze their descendants, while evaluating the phenotypic variability of ten quantitative variables. Analysis of the variance revealed a significant difference for the whole of parameters studied in the parents as in their descendants. Additive and non-additive effects are involved in the genetic control of the analyzed variables. The Hayman model (1954) seems acceptable for five variables on ten variables studied for which additive effects are more important than dominance effects. The analysis of the heterosis effect was significant for the characters tested. For the productivity of the plant, eight hybrids on twelve have expressed a positive heterosis compared to the mid- parent, six combinations on twelve have registered a positive heterosis compared to the over-batter parent and compared to the best variety with an overall heterosis of 17.53%.

The measurement of tracheal length in infants is difficult to perform in vivo. In adults, tracheal length may be consistent with age, but in infants, tracheal length may vary much more with age and other factors. This study used video rigid ventilation bronchoscopy to evaluate the length of the airway, concentrating on the population younger than 3 months old. There were 34 infants in this study: 14 boys and 20 girls. The mean length from the superior border of the vocal fold to the carina was 5.04 cm, and the mean tracheal length (from the ridge of the first tracheal ring to the carina) was 4.12 cm. There was no significant difference between boys and girls in the length from the vocal fold to the carina or in the tracheal length. The length from the vocal fold to the carina is best correlated to body weight, followed by body height and age.

ABSTRACT Two replications of a complete diallel cross experiment were performed among four partially inbred lines of mice. These inbred lines originated from a random-bred ICR strain and were produced by 12 generations of full sibbing (F ≃ 92%). Individual body weight was recorded for each animal at 12, 21, 42 and 56 days of age. Body weight gain traits were examined for intervals 12-21, 21-42 and 42-56 days. Simultaneous least squares analyses of inbred and linecrossed groups were used. Sex differences were highly significant for all traits. Replicate differences were significant but made a small contribution to the total variation. Inbred lines differed greatly. Crosses showed growth trends similar to their contemporary maternal and paternal inbreds. Heterosis was highly significant for all traits except 21-day weight. Inbreds were heavier at 12 days of age, but linecrossed progeny were superior to inbreds for all post-weaning weights. General combining ability was highly significant for 12- and 56-day weights and 21-42-day gain. Specific combining ability was highly significant for 21-day weight, 12-21- and 42-56-day gain. Significant maternal effects were found for all individual weights but not for 12-21- and 21-42-day gain. Residual reciprocal effects were significant for all traits. Estimated variances among linecrossed groups contained a large maternal component, a fluctuating additive genetic component and consistent non-additive genetic influence on all growth parameters measured.

The study was carried out on the biological aspect of Redbelly Tilapia, Coptodon zillii collected from Oyan Lake, Abeokuta North Local Government Area, Ogun State, Nigeria, with the aim of contributing to the baseline data for carrying out further studies on its ecology, conservation and development. A total of two hundred and fifty four fish (254) specimens were caught from the Ibaro landing site of the Lake between March and July, 2015. The total length (cm), standard length (cm), head length (cm), body width (cm), body depth (cm), snout length (cm), eye diameter (cm) and body weight (g) were measured. The stomach content was also assessed in order to determine its food and feeding habit. The mean total-length, standard-length, head-length, eye-diameter, snout-length, body-depth, body-width and body-weight during the study were 10.98±0.61cm, 8.56±0.14cm, 2.5±0.08cm, 3.67±0.15cm, 1.52±0.11cm,1.37±0.17cm, 4.05±0.07cm, 34.25±3.02g respectively and their ranges were (4.5-18.7cm), (3.2-15.2cm), (1.1-5.8cm), (2.0-6.8cm), (0.8-3.0cm), (1.1-4.8cm), (1.4-7.3cm) and (6.0-132.0g). A negative allometric (b<3) growth pattern was observed for the stock. The meristic characteristics of C. zillii were (DFR) XIV 10 – XVI 14; PVR, AFR III 8 –III 9; PFR 10 – 13 respectively. Stomach analysis showed that diatoms were the most abundant food items in the diet of C. zillii numerically, 29.98%, while desmids were the most abundant food items in terms of frequency occurrence, 27.82%. This study concluded that C. zillii is not morphometrically and meristically different from the already classified from previous studies. Also, C. zillii thrives well on available plants and detritus.

Investigations on the morphometric and meristic characteristics were conducted on grey mullet, Mugil cephalus collected from wetland of Ogun waterside Local government Area, Ogun state, Nigeria. A total number of ninety-one live specimens were caught from the wetland of Ogun waterside Local government Area, for a period of March to June 2012. The fish were immediately preserved on ice in order to slow down rate of decomposition and their total length (TL) (cm), standard length (SL) (cm), head length (HL) (cm), body width (BW) (cm) and body weight (g), were measured fresh within 24 hours. Its sex was also determined by dissecting out the gonads to reveal eggs or testes. The mean values of total length TL, standard length SL, head length HL, body width and body weight for both male and female of M. cephalus for the month of March to June were 18.0±1.1 and for male and 18.6±0.9 for female (M/F), 14.7±1.0 and 14.7±0.6 (M/F), 3.3±0.2 and 3.2±0.1 (M/F), 3.8±0.2 and 3.0±0.5 (M/F), and 52.3±5.5 and 66.7±1.1 (M/F). Gill raker of M. cephalus gave a different result as there was difference between male and female,108 – 138 (male), and 104 and 148 (female).The growth pattern for male species were near isometric with b = 2.53, female species was negative allometric (b = 2.88) and combined sexes was isometric (b = 2.80). Information obtained from the study will contribute to the baseline data for carrying future studies on its ecology and conservation and development.

The biology of T. caninus was examined in the field and in captivity over a 4-year period. The season of parturitions is restricted, with more than 87% of births between February and May. The sex ratio of the pouch young did not differ from parity and there was no significant difference between frequency of suckling of right or left teat, alternate teats being used during successive lactations. Measurements of 10 known-age individuals showed that head length (y) had a linear relationship to age (t) up to 210 days (regression, t = 2.917y - 19.355). Ear length and pes length were not linearly related to age. The young emerge from the pouch 175-200 days after birth, remain physically dependent on their mothers for the next 2-3 months and are weaned at > 240 days. Individuals in the field could be assigned to 1-year-old, 2-year-old or adult categories by a combination of head length, body weight and condition of external reproductive organs. Females may mature at 2 years old, although only 50% produce young at this age. The testis approximates adult size in the latter half of their third year. Survival of the dependent young is low, only 51.8% and 37.9% reaching 175 days and 1 year old respectively.
