The present study was conducted to know the pathogenicity and LD50 of Aeromonas hydrophila isolated from diseased climbing perch Anabas testudineus against apparently healthy homologous fish and the distribution of the bacteria in the organs of the experimentally infected fish. A total of 10 fish of average body weight of 18 g were used. For pathogenicity test, two different doses viz. 9.2 × 107 and 9.2 × 106 CFU/fish were injected intramuscularly. Pathogenicity of A. hydrophila was confirmed at water temperature of 28.53oC by the mortality of 40% to 100% of all tested fish within 4 to 9 days. The highest bacterial load was found to be 9.4 × 108 CFU/g in the intestine and the lowest bacterial load was found to be 2.8 × 103 CFU/g in the kidney of the tested fish. Four different serial concentrations, vide 9.2 × 107, 9.2 × 106, 9.2 × 105 and 9.2 × 104 CFU/fish of the bacteria were injected in each of four different groups of 10 fish. The calculated LD50 value at 27.3oC water temperature was 2 × 107 CFU/fish of 18 g of average body weight. In all the cases of intramuscular injection, external pathology was found. Reddish anal region and fin bases were observed. Injected A. hydrophila was re-isolated from liver, kidney and intestine of the challenged fish. It was understood that the isolate was a high virulent pathogen for A. testudineus.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16472 Progress. Agric. 22(1 & 2): 105-114, 2011

Pathogenicity of a bacterial isolate Aeromonas hydrophila recovered from naturally diseased shing fish was investigated against catfishes (Heteropneustes fossilis and Clarias batrachus), carps (Labeo rohita, Catla catla and  Cirrhinus cirrhosus) and perch (Anabas testudineus) of average body weight of 20.4 g for H. fossilis, 25.6 g for C.  Batrachus, 35.2 g for L. rohita, 25.7 g for C. catla, 30.5 g for C. cirrhosus and 20.3 g for A. testudineus. Two different  doses viz. 6.7 × 106 and 6.7 × 105 CFU/fish were injected intramuscularly. Pathogenicity of A. hydrophila was confirmed at water temperature of 30°C by mortality of 60% to 100% of all the tested fishes within 2-11 days. Injected  A. hydrophila was re-isolated from liver, kidney and intestine of all the tested fishes. The highest bacterial loads in catfishes were found to be 5.5 × 108 CFU/g in the liver of H. fossilis and 5.6 × 107 CFU/g in the intestine of C.  batrachus. The lowest bacterial loads were found to be 2.2 × 102 CFU/g in the kidney of H. fossilis and 2.4 × 103 CFU/g in the liver of C. batrachus. The highest bacterial loads in carps were found to be 4.9 × 109 CFU/g in the liver  of C. catla, 7.7 × 108 CFU/g in the intestine of L. rohita and 5.8 × 108 CFU/g in the intestine of C. cirrhosus. The   lowest bacterial loads were found to be 2.7 × 104 CFU/g in the kidney of C. catla, 3.0 ×104 CFU/g in the kidney of L   rohita and 5.6 × 103 CFU/g in the kidney of C. cirrhosus. The highest and lowest bacterial load in perch was found to  be 6.4 × 10' CFU/g and 1.6 × 102 CFU/g in the intestine and kidney of A. testudineus respectively. In all the cases of  intramuscular injection, external pathology was found. Reddish anal region and fm bases were observed. It was   understood that the isolate was a highly virulent pathogen for the challenged fishes.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12108   J. Bangladesh Agril. Univ. 10(1): 157–161, 2012

Naturally diseased climbing perch Anabas testudineus was confirmed to be caused by Aeromonas hydrophila bacteria by aeromonas isolation medium (AIM), 0/129 vibriostatic agent and esculin hydrolysis. Such naturally diseased koi fish weretreated with four antibiotics: captor (chlortetracycline hydrochloride BP 45%), renamox 15% -Vet (amoxicillin trihydrate BP), oxy-Dox-F (oxytetracycline 20% and + doxycycline 10%), renaquine 20% -Vet (flumequine) at lower, recommended and higher doses were performed to examine the efficacy of the drugs. Captor was given at doses of 0.8, 1.0 and 1.2 g/3 litres of water separately. Doses of renamox 15% -Vet were given at 0.8, 1.0 and 1.2 g/litre of water. Doses of oxy-Dox-F were 0.8, 1.0 and 1.5 g/Kg body weight and doses of renaquine were 10, 12, and 15 mg/Kg body weight. Among the four antibiotics, effect of captor and renaquine at recommended dose showed the best result where 100% fish were recovered. However, renamox and oxy-Dox-F showed best result at higher dose.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

The present study was conducted to determine the early sex in turkeys by observation of the differences in body weight between male and female birds. A total of 30-day old black color unsexed poults having almost similar body weight at hatching were considered for the experimentation and housed at the Poultry Farm of Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. All birds were reared up to 12 weeks of age under intensive management with supplementation of commercial broiler starter and grower feeds. Birds were reared under similar management conditions. Significantly higher (p<0.01) body weight was attained in male poults (104g/bird) than the female (90g/bird) at the end of 1st week of age. Similarly, at the end of 2nd week of age higher (p<0.01) body weight attained by male poults (198.31g/bird) than the female (162.13g/bird). At the end of 3rd weeks of age male poults attained higher (p<0.01) body weight (307.23g/bird) than the female (251.33g/bird). After 4 weeks of rearing, male turkeys attained significantly higher (p<0.01) live body weight (424.46g/bird) than the female turkeys (347.87g/bird). The weekly average body weight gains of male and female birds were 94.18g/bird and 76.5g/bird, respectively. Thus, the male and female birds were successfully identified on the basis of differences in their body weight. Weekly feed intake for both the male and female birds was also increased with their age. Up to 4 weeks of age, both the male and female poults consumed same amount of feed (753.46g/bird). The FCR of male and female poults differed non-significantly in 1st, 3rd and 4th week. On the contrary, in 2nd week of age the FCR of male poults (1.60) was significantly lower (p<0.01) than female (2.11). Survivability was 100% up to 4th week of age irrespective of sex of the poults. The birds were reared up to 12 weeks of age until to confirm their sex by observation of the phenotypic appearance. Results of the phenotypic observation of male and female birds correspondence hundred percent accuracy with the results obtained in body weight based differences between male and female birds. It is therefore concluded that farmers can identify male or female poults as early as first week of age on the basis of body weight differences. Progressive Agriculture 31 (3): 218-226, 2020

The objective of this work was to evaluate the quantitative characteristics of carcasses of Moxotó and Canindé goats finished in feedlots and fed diets of two levels of energy. It was used 40 castrated young goats, 20 from Moxotó breed and 20 from Canindé breed, each one with an average body weight of 15.2 kg. The animals were fed with diets containing 2.20 and 2.71 (Mcal/kg DM). The experimental period lasted 86 days. There was no difference among the barometric measures of Moxotó and Canindé kids. Canindé goats showed higher final weight, higher weight after fasting and higher hot and cold carcass weights when compared to the Moxotó animals. Animals that consumed diets with higher energy level had higher final weight and conformation as well as higher carcass yield. Considering the percentage values of the commercial meat cuts, no difference among treatments was observed. The diet was the factor that most influenced the non-constituent components of the carcass of Moxotó and Canindé goats. In general, animals belonging to the Canindé breed presented higher quantitative characteristics than the Moxotó breed. Supply of diets with higher energetic level (2.71 Mcal/kg DM) for goats from Moxotó and Canindé breeds, in feedlots, favors the production of carcass with higher yields and heavier commercial meat cuts.

Penampilan fenotipik suatu organisme ditentukan oleh faktor genetik dan dipengaruhi oleh faktor lingkungan tempat organisme tersebut hidup. Dalam beberapa kasus, interaksi antara faktor genetik dengan lingkungan juga berpengaruh terhadap penampilan fenotipik yang dihasilkan. Penelitian ini bertujuan untuk mempelajari interaksi antara faktor genetik dengan lingkungan, daya adaptabilitas dan stabilitas penampilan fenotipik khususnya bobot individu pada empat varietas unggul ikan nila yang dipelihara di tiga lokasi berbeda. Ikan nila varietas GMT, merah NIFI, NIRWANA dan BEST dipelihara di tambak payau di Indramayu, kolam air tenang di Sukamandi dan karamba jaring apung di Waduk Cirata, Kabupaten Cianjur, selama empat bulan pemeliharaan. Benih ikan nila diberi pakan pelet komersial dengan kandungan protein kasar 28%-30%, sebanyak 10%; 7,5%; 5%; dan 2,5% dari biomassa ikan masing-masing pada bulan pertama, kedua, ketiga, dan keempat. Pakan diberikan dengan frekuensi dua kali setiap hari. Hasil penelitian menunjukkan bahwa bobot ikan nila secara nyata dipengaruhi oleh faktor genetik, lingkungan, serta interaksi antara kedua faktor tersebut. Selain ikan nila GMT, tiga varietas ikan nila yang diuji mempunyai adaptabilitas lingkungan relatif sempit, serta stabilitas penampilan fenotipik karakter bobot individu relatif rendah. Hal ini mengindikasikan bahwa pengembangan budidaya ikan nila GMT dapat dilakukan di semua lokasi, sedangkan ikan nila merah NIFI, NIRWANA, dan BEST akan optimal jika dilakukan di lokasi tertentu saja.Phenotypic performance was determined by genetic and environment factors and their interaction. This study was conducted to examinethe present of interaction both of genetic and environment factors, adaptability, and stability of phenotypic performance of four varieties of tilapia which maintained in three different location. GMT, red NIFI, NIRWANA, and BEST tilapia strains were reared for four months in net cages in Cirata reservoir in Cianjur, in earthen ponds in Sukamandi and in brackish water ponds in Indramayu. All fish were fed with commercial pelleted feed contained of crude protein 28%-30%, about 10%, 7.5%, 5%, and 2.5% each day in 1st, 2nd, 3rd, and 4th month, respectively. The results showed that tilapia’s phenotipic performance especially the average body weight was significantly affected by genetic factor, environment factor, and interaction both of them factors. Except the GMT, all tilapia strains used in this study have narrow phenotypic adaptability and stability, especially in average body weight. This results indicated that GMT tilapia strain can be farmed in various areas, but red NIFI, NIRWANA, and BEST tilapia strains are most likely in a specific location.

Introduction: Preterm delivery is the delivery before 37 weeks of gestation are completed. The incidence of preterm birth ranges from 5 to 15%. Aims of the study were to determine the average body weight, Apgar score after one and five minutes, and the frequency of the most common complications in preterminfants.Methods: The study involved a total of 631 newborns, of whom 331 were born prematurely Aims of this study were to (24th-37th gestational weeks-experimental group), while 300 infants were born in time (37-42 weeks of gestation-control group).Results: Average body weight of prematurely born infants was 2382 grams, while the average Apgar score in this group after the fi rst minute was 7.32 and 7.79 after the fifth minute. The incidence of respiratory distress syndrome was 50%, intracranial hemorrhage, 28.1% and 4.8% of sepsis. Respiratory distresssyndrome was more common in infants born before 32 weeks of gestation. Mortality of premature infants is present in 9.1% and is higher than that of infants born at term.Conclusions: Birth body weight and Apgar scores was lower in preterm infants. Respiratory distress syndrome is the most common fetal complication of prematurity. Intracranial hemorrhage is the second most common complication of prematurity. Mortality of premature infants is higher than the mortality of infants born at term birth.

The objective: to develop a regional gestational percentiles table of body weight for newborns in Kiev and Kyiv’s oblast. Materials and methods. Data of the body weight of newborns were collected from Kyiv City Perinatal Center from January 2016 by January 2017. The total number included 5244 live births in the period of gestation 40+0–40+6 weeks of gestation. The standard deviation of the body weight, expressed as the percentage of the average body weight of all newborns, as well as the percentil calculator developed by Hadlock et al, supported by the WHO (2008), was used to generate the percentages and curves of the body weight. Materials and methods. A newborn body weight percentile table was constructed, depending on the gestational age. Differences were observed between the current average body weight of newborns for Kyiv and current WHO links. Conclusion. We found a rise in the average body weight of newborns, which we associate with excessive, unbalanced diet and the prescribing of a complex of multivitamins and biologically active substances during pregnancy. This indicates the importance of using this table for differential diagnosis of normal fetal growth from intrauterine growth restriction and small for fetal gestational age within the region of Kyiv and oblast. Key words: delayed fetal growth, percentile table of the city of Kiev, average body weight of newborns, percentile schedule.
