Slug Girasia crocea (Godwin-Austen) is an herbivore, feeds on soft twigs or leaves of plants. The slug G. crocea are active for period of March-November. They use to overcome winter month (December-February) through hibernation. Sometimes they were seen to winter morning. In nature, they have a wide range of food acceptability. The feeding and foraging activities are confined to night ours. In nature, breeding period extends from March to November. The egg laying and other breeding activities are maintained at an equal temperature during the whole active period. In laboratory, they thrived well on Amranthus sp. And Spinacea sp., while temperature. They attained adult at the age of 196 days to 201 days. They lay eggs lay in cluster. The eggs are round in shape and white in colour. Individual slugs on an average, added 9.5mm, 2.5mm and 40mg; 13.5mm, 3.5mm and 40mg; 17mm, 5mm and 50mg; 24mm, 5mm and 60 mg; 35.5mm, 6 mm and 485mg; 52mm,10mm and 1190mg; 65mm, 8.5 and 1114mg; 65mm, 9.5mm and 1117mg and 57mm, 10mm and 1134mg to their body length, body width and body weight respectively at temperature of 26 - 31.50C during the study period. On an average an egg was measured 3.85mm in diameter.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22071 J. Environ. Sci. & Natural Resources, 6(1): 227-232 2013

The fecundity for 40 wild freshwater spiny eel Mastacembelus armatus estimated from Mymensingh region, Bangladesh during the breeding period from March to July 2004. The estimation of fecundity (mature ova) ranged from 3,155 to 24,684 eggs, the maximum fecundity was observed from a fish measuring 535 mm in length and 350 g in weight and the minimum from a fish of 260 mm in length and 51 g in weight. The maximum ova diameter was 2.75 mm in the month of April and minimum was 1.45 mm in May with a median of 2.08 mm in the month of March and then a sudden decrease in July (1.84 mm). The average number of ova present per gm body weight was 70.19 while the average number of ova present per gm ovary weight was 888.04. Fecundity increased with the increase in length and weight of the fish. Maximum GSI value for female spiny eel was 21.67% in the month of March and the minimum GSI value for the same gender was 3.30% in April and the median GSI value for the same was 8.06% in the month of May. The regressions of fecundity on body length, body weight and gonad weight of female spiny eels were Log F = 2.59 - 2.72 × Log L (r = 0.86), Log F = 1.00 + 1.84 × Log BW (r = 0.88) and Log F = 0.69 + 3.25 × Log GW (r = 0.75) respectively, where F is fecundity, L is total length (mm), BW is body weight (g) and GW is gonad weight (g). Fecundity-total length and fecunditybody weight gave a better relationship in comparison with fecundity-gonad weight relationship.

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.

Studies on the differences in the morphological characteristics of freestyle wrestlers belonging to related ethnic groups from South Siberia and Central Asia have not been previously conducted. This research aimed to perform a comparative analysis of the anthropometric and functional characteristics of freestyle wrestlers from two mono-ethnic samples: the Altaians and the Mongols. A total of 99 freestyle wrestlers were examined (mean age 25.0 ± 2.6 years). The anthropometric survey included measuring longitudinal (body length and length of segments), transverse (shoulder and pelvis width, transverse and sagittal diameters of the chest), circumferential (trunk and limb circumference) parameters, as well as body weight and skinfold thickness on the trunk and limbs. Body composition was determined by multi-frequency bioelectrical impedance analysis (ABC-02 MEDASS, Russia). During the stratification of athletes by the total body measures (weight and height), we identified anthropometric differences that can be either interethnic or those formed under the influence of targeted selection. The comparative analysis of anthropometric features of the longitudinal and transverse development of the skeleton allows us to suggest that the high values of the transverse diameter of the chest as well as relatively long legs and short arms typical of the Altaians are preserved by sports selection and are manifested in a wide range of height and weight values. The greatest variability is characteristic of the body’s fat component. Within the normal body length/weight ratio (body mass index ranging between 22.0 and 24.9 kg/m2), Altaian athletes showed greater fat mass but lower level of subcutaneous fat deposition compared to Mongolian wrestlers with the same body weight.

Gourami (Osphronemus gouramy Lac.) as one of the freshwater fishes, are easily to be cultured but slow in growth rate. One of the ways to enhance their growth rate is by feeding them with high nutritious food. Sargassum sp. and inositol are known compound able to stimulate the growth of some fishes. The study was conducted to determine the effect of Sargassum sp and inositol on commercial feed to the growth rate and survival of juvenile gouramy. The study was conducted from January to April 2015 in Aquatic Laboratory of Biology Department - University of Lampung. Completely randomized designed was used with 4 treatment groups and 5 replications. Anova and Tukey at 5% levels were applied to this study. The result indicated that addition of inositol and Sargassum sp on commercial food significantly affected the gourami growth parameters such as the body weight, body length, body width as well as juvenile gouramy spesific growth rate and their survival rate.

Linear Body

Data on body weight and linear body measurements (LBMs) namely ear length (EL), body width (BW), body length (BL), Head to shoulder (HS), Shoulder to tail (ST) and length of leg (LL) of 363 progeny of locally adapted Dutch , New Zealand White and crossbred rabbits at 3,6,9 and 12 weeks of age were analyzed to obtain phenotypic correlations between the various traits and prediction equations for body weight, using different linear body measurements. There were high and positive correlations between each of the linear body measurements and body weight and between the LBM themselves. The values ranged between 0.57 and 0.85, 0.34 and 0.89, 0.27 and 0.83 and 0.41 and 0.75 in weeks 3, 6, 9 and 12, respectively. Hence, it was possible to predict body weight of live rabbits from their linear body measurements, as an aid to farmers in areas where sensitive scales are not available. Except in purebred New Zealand White NZWxNZW, body: length (BL) was a good predictor of 3- week body weight (IBW) in all breed groups. Body width (BW) and BL only were good predictors of 6-week body weight in all breed groups. For predicting 9- week body weight, shoulder to tail drop (ST) was important in all breed groups in addition to either BW, ear length (EL) or body length (BL). ST and BW were important predictors of 12-week body weight generally in all breed groups.

Records of body weight (BW) and linear body measurement (LBMs), namely body length (BL), body width (bwh), heart girth (hg), height-at withers (HW), shoulder-to-tail drops (ST), ear lenght (EL), head-to-shoulder (HS), lenght of fore limb (LFL), lenght of hind limb (LHL) and head circumference (HC) taken on 72 kits produced through complete dialled crosses were used to estimate heterosis and recipocal effects. The crosses involved New Zealand White (NZW), Dutch (DT) and Cchinchilla (CH) breeds of rabbit. Only NZW x DT and CH x DT crosses showed heterosis for BWs, indicating that non-additive sults for all effects of genes could be important for the LBMs were generally similar. Recipocal effect was not significant (p<0.05) for all traits. suggesting that any of the breeds may be used as sire or dam in planned crossesbreeding programmes.

Nine neonatal and juvenile snakes, four vipers and five nonvipers, were fed rodent meals varying in size, expressed as percent of snake body weight. The number of mandibular protractions and the time to complete swallowing were recorded, with both measures increasing linearly as a function of meal size. These young snakes routinely swallowed meals that were 50% of body weight, and ranged up to 80%, far higher than meals reported by previous workers studying adult vipers (36.4%) and nonvipers (18.4%). Furthermore, the slopes of regressions relating mandibular protractions to meal size in all of our snakes were lower than comparable slopes for adult vipers or nonvipers. We hypothesized that the relatively long and wide skulls of young snakes (i.e., as proportion of body length) were responsible for these ingestive accomplishments, with negative allometric growth being responsible for performance changes during ontogeny.

Abstract Raramuri Criollo (RC) are one of 33 known biotypes of heritage Criollo cattle that exist throughout the Americas today. They have been raised by the Tarahumara peoples of the Copper Canyon in Chihuahua, Mexico, for over 400 years and exhibit remarkable rusticity and adaptation to harsh grazing environments. To date, no quantitative phenotypic description of this biotype exists. Our objective was to characterize RC cattle via 26 phenotype traits to provide a preliminary biotype standard. Twenty-eight multiparous RC cows, 4 primiparous heifers, and 4 bulls were selected from a purebred herd of approximately 200 animals at the USDA-ARS Jornada Experimental Range. These 36 animals were selected by a Criollo cattle expert based on body conformation correctness. SAS 9.4 was used to determine means, SEs or frequency of measured traits. Multiparous pregnant and cycling cows averaged 366.8 ± 9.8 kg live body weight, 121.8 ± 0.9 cm withers height, horn widths of 60.3 ± 1.6 cm, horn diameters of 5.7 ± 0.1 cm, chest girths of 183.6 ± 12.0 cm, hip widths of 44.5 ± 0.5 cm, flank girths of 52.2 ± 0.9 cm, body length of 90.0 ± 1.7 cm, neck lengths of 52.0 ± 0.9 cm, and tail lengths of 83.3 ± 1.4 cm. Bulls consistently averaged higher values for all traits and weighed 618.2 ± 9.8 kg with scrotal circumferences of 36.8 ± 0.7 cm. RC cattle exhibited mostly convex nose bridges (89%), open-back horns (49%), black muzzles, hooves, and eyes (62, 69, and 81%, respectively), small ears (78%), oblique eyes (70%), high-set tail heads (86%), short hooves (95%), and short hair (78%). Our preliminary characterization of RC phenotypes will be useful in selecting RC individuals for genotypic evaluation to eventually maintain a distinct purebred registry of this Criollo biotype.

Abstract Background Rezafungin is a novel echinocandin antifungal in development for treatment as well as prevention (prophylaxis) of invasive fungal infections. STRIVE (NCT02734862) is a global, randomized, double-blind, placebo-controlled, Phase 2 trial evaluating safety and efficacy of IV rezafungin once weekly (QWk) for treatment of candidemia and/or invasive candidiasis compared with standard-of-care (IV caspofungin once daily with optional oral stepdown). Here we report pharmacokinetic (PK) data from the completed STRIVE trial analyzed by patient demographics at baseline. Methods Rezafungin Day 8 trough (Cmin) concentrations from patients treated with rezafungin were summarized categorically by race (black or white), sex (male or female), and geographic region (North America [NA], or Europe [EU]), or plotted versus continuous variables of age, body weight, body mass index (BMI), and body surface area (BSA). As the first dose of rezafungin was 400 mg for all rezafungin-treated patients, data from both dose groups (Group 1: 400 mg QWk; Group 2: 400 mg in Week 1 followed by 200 mg QWk) were combined in this analysis. Results Rezafungin mean Cmin (SD) values were 1.8 (0.7) and 2.3 (1.2) in black and white patients, 1.9 (1.0) and 2.6 (1.2) in males and females, and 1.9 (0.6) and 2.4 (1.3) in patients from NA and EU. There were small differences in point estimates between the groups, but there was a great deal of overlap and the differences are not expected to be clinically meaningful (Figure). Similarly, no trends in Cmin values were observed across a range of ages (20-80 years), weights (~40-155 kg), BMI (~15-65 kg/m2), and BSA (~1.4-2.4 m2). Figure Conclusion No meaningful differences in rezafungin Cmin values were observed in patients grouped by sex, race, or geographic region, or across a wide range of patient factors, including age and body weight and size. These findings indicate that a single rezafungin dose regimen can be expected to provide consistent PK across diverse patient populations. Disclosures Shawn Flanagan, PhD, Cidara Therapeutics, Inc.
