Yustiati A, Andriani Y, Herawati T. 2017. Sustainable aquaculture development in floating nets at Cirata reservoir (West Java, Indonesia) through single-sex nilem fish introduction. Asian J Agric 1: 29-34. This research aims to develop a sustainable aquaculture system using single-sex nilem fish in trophic level-based farming and to analyze the feeding habits, types of meal and preference level of the feed in nilem farmed in Cirata Reservoir. In addition, it also aims to determine the fish's ability as a biocontrol agent for water cleaning by measuring the ability to utilize periphyton attached to the floating nets. Research conducted at the Laboratory of Ciparanje, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran and floating nets of Cirata reservoir. Observation of the performance of biological testing and food feeding applies the experimental design method of Completely Randomized Design (CRD) consisting 5 treatments and 3 replications. The five treatments include non-artificial feeding (treatment A), 1% feeding of body weight per day (treatment B), 2% feeding of body weight per day (treatment C), 3% of feeding of body weight per day (treatment D), and 4% feeding of body weight per day (treatment E). The results showed there was no difference in the survival and growth levels of the female single-sex fish given both commercial and non-commercial feed. The highest feed efficiency was observed in the 3% of commercial feeding treatment, amounting to 55.30%. The fish are herbivorous and generalist with trophic levels between 1.03% and 1.45% eating planktons for living. Fish fed with artificial food to 4% of the biomass still graze on phytoplankton as the main source of food, but adapt by changing the natural feeding and tend to be ineffective in utilizing the available food resources in the waters. During the study, the types and amount of periphyton attached to the nets have decreased. Higher commercial feeding level results in the higher density of periphyton in the floating nets.

The Difference

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

Abstract. Asmara IY, Garnida D, Partasasmita R. 2020. Crowing characteristics of Pelung chickens at different age and body weight. Biodiversitas 21: 4339-4344. Crowing characteristics such as duration, frequency, and intensity are important factors to consider in determining a good Pelung. Age and body weight are among other factors being assumed to affect crowing characteristics. The study was conducted to determine the crowing characteristics of different age and body weight. A survey was carried out in Bandung, Cianjur, and Sukabumi Districts, West Java Province, Indonesia in which a total of 98 birds was selected using a purposive technique. The observed parameters were the duration, frequency, and intensity of crowing. The duration was the length of crowing measured by seconds. Frequency is several crowing in a particular time measured by times. Intensity is the magnitude of crowing measured by decibel. The crowing was recorded from 7 AM-2 PM. Data were analyzed using descriptive analysis and Mann-Whitney U Test to compare data differences between research areas. The study found that the crowing duration of Pelung roosters tends to increase in older birds, but the decrease in heavier birds. Crowing frequency increase along with age and body weight. Crowing intensity is similar in different age groups, while the intensity tends to decrease in the heavier group. The results provide evidence that age and body weight of chickens are an important aspect in Pelung contest and age should be considered as a new category in Pelung contest.

The effect of 17 beta-estradiol 3-benzoate (10 micrograms.0.1 ml sunflower oil-1.100 g body wt-1) on exercise performance, tissue glycogen utilization, and lipid availability was determined in male rats. In experiment 1, estradiol or oil was administered 1 h or 1–6 days before a treadmill run to exhaustion. No differences in body weight between oil- and estradiol-administered animals were observed during the 6-day treatment. Animals receiving estradiol for 3–6 days ran significantly longer and completed more work than oil-administered animals. Significant degradation of red and white vastus muscle, myocardial, and liver glycogen was observed in all animals run to exhaustion. In experiment 2, animals were administered estradiol for 5 days and then run for 2 h. The submaximal run for 2 h significantly reduced tissue glycogen content in red and white vastus muscle, heart, and liver of oil-administered animals. The latter effect was attenuated in both vastus muscles, liver, and myocardial tissues in the estradiol-administered animals. Estradiol administration significantly increased plasma fatty acids and lowered plasma lactate during the submaximal run. These data indicate that when body weight remained constant between groups of male rats, estradiol administration for 3–6 days increased exercise performance. Furthermore, estradiol administration for 5 days resulted in greater lipid availability and less tissue glycogen utilization during submaximal running for 2 h.

The trophic ecology of the chihuil sea catfish Bagre panamensis was studied through high-resolution variations in its feeding habits and trophic position (TP) in the SE Gulf of California, relevant to sex, size and season. The combined use of stomach content (SCA) and stable isotope analysis (SIA) allowed us to perform these analyses and also estimate the TP of its preys. Results of this study show that the chihuil sea catfish is a generalist and opportunistic omnivore predator that consumes primarily demersal fish and peneid shrimps. Its diet did not vary with climatic season (rainy or dry), size or sex. Results from the SIA indicated high plasticity in habitat use and prey species. The estimated TP value was 4.19, which indicates a tertiary consumer from the soft bottom demersal community in the SE Gulf of California, preying on lower trophic levels, which aids in understanding the species' trophic role in the food web. Because this species and its prey are important to artisanal and industrial fisheries in the Gulf of California, diet assimilation information is useful for the potential establishment of an ecosystem-based fisheries management in the area.

ABSTRACT The activity of telithromycin, a new ketolide, was evaluated in vitro and in vivo against Mycobacterium avium complex (MAC) strains. The MIC of telithromycin for several M. aviumisolates obtained from the blood of AIDS patients ranged from 16 to >128 μg/ml (MIC at which 90% of isolates are inhibited, >128 μg/ml), and the compound did show activity in the macrophage system at concentrations greater than 8 or 16 μg/ml, but this was dependent on the MAC strain used. Telithromycin was then administered to mice infected with MAC strain 101 for 4 weeks at doses of 100, 200, or 400 mg/kg of body weight/day. Treatment with 100 and 200 mg/kg/day was bacteriostatic, but at 400 mg/kg/day telithromycin was bactericidal for MAC strains. The frequency of the emergence of resistance to telithromycin was low despite prolonged usage (12 weeks). This study demonstrates that telithromycin is active in vivo against MAC and warrants further evaluation.

Several idiosyncratic and genetically correlated traits are known to extensively influence leadership in both domestic and wild species. For minor livestock such as camels, however, this type of behavior remains loosely defined and approached only for sex-mixed herds. The interest in knowing those animal-dependent variables that make an individual more likely to emerge as a leader in a single-sex camel herd has its basis in the sex-separated breeding of Canarian dromedary camels for utilitarian purposes. By means of an ordinal logistic regression, it was found that younger, gelded animals may perform better when eliciting the joining of mates, assuming that they were castrated just before reaching sexual maturity and once they were initiated in the pertinent domestication protocol for their lifetime functionality. The higher the body weight, the significantly (p < 0.05) higher the score in the hierarchical rank when leading group movements, although this relationship appeared to be inverse for the other considered zoometric indexes. Camels with darker and substantially depigmented coats were also significantly (p < 0.05) found to be the main initiators. Routine intraherd management and leisure tourism will be thus improved in efficiency and security through the identification and selection of the best leader camels.
