Data on the biological aspects of Charybdis anisodon (De Haan, 1850) were still very limited. This study was aimed to determine the distribution of size, growth type, sex ratio and spawning season of C. anisodon in Lasongko Bay, Central Buton, Southeast Sulawesi. Crab collection was conducted from May 2013 to March 2014 using a crab gillnet. The carapace width of males and females C. anisodon ranged between 3.05-7.61 cm and 3.45-7.98 cm, respectively. Mann-Whitney test showed that width and length of carapace of males and females were significantly different (p<0.05). Type of growth of carapace width-body weight male and female were both allometric negative. Carapace length-body weight relationships of the males was isometric, but it was allometric negative for females. Spatially and temporally, the sex ratio of C. anisodon showed a variation, and the total sex ratio was 1: 0.38. The spawning season of C. anisodon tend to occur throughout the year.

The studies of the dynamics results of body weight, absolute and daily average, relative increases averaging bulls of Ukrainian black-and-white and Ukrainian red-and-white dairy cattle. Researches are conducted in the conditions of POSP «Napadivske» Kalyinivka district of the Vinnytsya area after materials of primary pedigree account. In an economy use the whole-year of the same type feeding. In the structure of ration 40% make the concentrated sterns and also high-quality silage and soilage. Average daily increases of bulls for period of age to realization for a slaughter made over 1000 grammes. The dynamics of growth of living mass, absolute, average daily and relative increases of bulls, is analysed Ukrainian black-and-white and Ukrainian red-and-white dairy cattle. Living mass and weight gain researches of age to 12-monthly age with an interval in 3 months after the generally accepted methods. Materials of researches are worked out the methods of mathematical statistics with the use of programmatic package of Statistica 8.0. Living mass of bulls of the second group at birth made 36,3 kg, that anymore on 0,8 kg by comparison to new-born bulls of the first group. In all next periods living mass of animals of the second group was greater as compared to the animals of the same age of the first. In 3 months advantage made 1,7 kg, in 6 months – 4,6 kg (P>0,95), in 9 months – 8,8 kg (P>0,95), in 12 months – 12,5 kg (P>0,99). Difference of absolute increases of bulls of the second group above the bulls of the same age of the first of age to to 3-monthly age made 0,8 kg in behalf of animals of the second group. In a period 3-6 months a difference is after this index between the first and second groups made 2,9 kg in behalf of the last. In periods 6-9 and reliable advantage of animals of the second group is 9-12 months set above the bulls of the same age of the first on 4,1 kg (P>0,95) and 3,7 kg (P>0,95) accordingly. In a period of age to 18-monthly age absolute increases of bulls of the second group were greater by comparison to bulls first on 12,5 kg (R>0,99). Average daily increases of bulls of the second group of age to 3-monthly age made 763,0 grammes, that anymore on 8,9 grammes by comparison to bulls of the first group. In periods 3-6 months the average daily increases of animals of the second group prevailed the bulls of the same age of the first on 32,6 grammes. In a period 6-9 months the average daily increases of animals of the second group were made by 1045,9 grammes, that for certain anymore on 45,9 grammes (P>0,95) by comparison to the bulls of the same age of the first. Maximal increases of bulls were in a period 9-12 months and made 1210,4 grammes in the animals of the second group and 1168,9 grammes – for the bulls of the same age of the first, that for certain anymore on 41,5 grammes (P>0,95). In a period of age to 12-monthly age the average daily increases of bulls of the second group were made by 970,6 grammes, that was for certain anymore on 31,8 grammes (R>0,99) by comparison to the bulls of the same age of the first group. Relative increases of bulls of both groups were high. From birth to 3-monthly age greater increases had bulls of the first group – 97,8%, and in periods 3-6, 6-9 and 9-12 months greater were increases of bulls of the same age of the second group – 56,4; 40,1 and 32,4% accordingly. For all probed periods of reliable advantage it is not discovered between the compared groups. It is set researches, that at the identical terms of feeding and maintenance more rapid bulls grow Ukrainian red-and-white dairy cattle. In all age-old periods they prevailed the bulls of the same age of the Ukrainian black-and-white dairy cattle, in a that number, beginning from 9-monthly age, advantage was reliable (P>0,95–0,99). Average daily increases of bulls of two breeds were the least in a period of age to to 3-monthly age – 754,1-763,0 grammes, and most in a period 9-12 months – 1168,9–1210,4 grammes.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

Colour Form

A multivariate approach has been used to study morphological variation in the blue and orange-form species of rock crab of the genus Leptograpsus. Objective criteria for the identification of the two species are established, based on the following characters: width of the frontal region of the carapace; width of the posterior region of the carapace (rear width); length of the carapace along the midline; maximum width of the carapace; and the depth of the body. The first canonical variate, which differentiates between the two species, represents a contrast between the carapace width relative to the width of the front lip and the depth of the body; the blue-form species has a greater relative carapace width than has the orange form. The second canonical variate, which presents a contrast between the rear width and the carapace length, identifies males and females within each species; males have a greater relative carapace length than have females. All individuals, including 20 not used in the study, were correctly identified for colour form. The clear separation of the blue and orange forms achieved by canonical analysis supports the previously determined specific status of the two forms.

One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.

In total, 240 three-weeks-old sexed birds (191.06±6.01g), 120 + 120 from Lakha, Mushki, Peshaweri and Mianwali varieties of local Aseel were used to determine the influence of selenium forms on growth during three growth phases. Birds were divided into four equal groups, 60 birds/variety (30 + 30 ), further subdivided into A, B and C treatment groups, 10 bids/treatment. Each group was allocated starter, grower and finisher diets. Group A was offered the diet supplemented with 0.3 ppm Se-enriched yeast and the diet of group B included 0.3 ppm sodium selenite, while group C was fed with un-supplemented control diet. Birds were maintained individually for 18 weeks. Feed intake was decreased, while, body weight gain, feed conversion ratio (FCR) and body weight gain were improved in males and females of Lakha, while best results detected in males during all growth phases in Se-enriched yeast fed groups. In conclusion, Se-enriched yeast had the positive effect in improving growth parameters of native Aseel.

This paper presents the information about morphological variability and sexual dimorphism of the stone crayfish (Austropotamobius torrentium) in the area of Korana River in Mrkonjic Grad. The crayfish were caught by hand made baited traps from October 2018 to May 2019. A total of 46 crayfish were caught, of which 33 males and 13 females. The dimensions of eight morphometric characteristics: body weight (W), body length (TBL), rostrum length (ROL), rostrum width (ROW), claw length (CLL), carapace length (CPL), carapace width (CPW) and abdomen length (ABL), were analyzed, both in males and females. Also, the body condition was determined for all individuales. The measurements results of morphometric characteristics partially matched into the alredy known range of variations. These data presens first ones for the observed area. By using Mann-Whitey U-test, it was noted that there are significant differences between the sexes for W, TBL, CLL, CPL, CPW and ABL. These resuls could be explained by sexual dimorphism of the stone crayfish.

Portunus Segnis

The blue swimming crab Portunus segnis (Forskål, 1775) is one of the earliest Lessepsian invaders of the Mediterranean Sea, and is recorded since decades in various areas of the Mediterranean. Its presence in the southeastern Tunisian coasts (Gulf of Gabes) is, however, very recent. Allometry, condition factor and growth of P. segnis were studied along the Gulf of Gabes coasts. Sampling was performed by artisanal fishing gears as well as trawl net during a one-year period (October 2015 to September 2016) as processed 4971 crabs were collected. The crab carapace width (CW) ranged from 45 to 168 mm for males and 50 to 159 mm for females. The crab carapace length (CL) was 22.02-89.20 mm and 38.70-85.28 mm, respectively for males and females. The carapace width-carapace length, carapace width- front, carapace width-carapace height and carapace width-weight relationships were studied in separate sexes of crab. The covariance analysis indicates a significant difference between the two sexes with respect to the carapace width-carapace length and the carapace width-weight relationships. The condition factor ranged between 0.0042 and 0.0118 with a mean of 0.0078. The condition factor decreased with increasing crab size. The Von Bertalanffy growth parameters CW∞, K and t0 were estimated on the basis of Length-frequency modal progression analysis methods. The mean values of L∞ (mm), K (year-1) and t0 would be, respectively, 206.48 mm, 1.34 and -0.130 for males; 183.89 mm, 1.42 and -0.127 for females and, 190.60 mm, 1.02 and -0.177 for combined sexes.
