The objectives of this investigation was to demonstrate that genotypes of calpastatin (CAST) Ser368Arg and ryadonide receptor 1 (RYR1) g.1843C>T may affect the carcass traits of pigs. Association analysis of the aforementioned SNPs was performed on 518 pigs included eight commercial crossbreeds and one pure pig breed. All pigs were slaughtered at average body weight of 113kg. Genotypes at the SNPs were determined by PCR-RFLP. There were found only two genotypes of RYR1 gene: CC (428 pigs) and CT (90 pigs) in this study. The effect of allele C compared to allele T on the higher fat content of pig carcass was confirmed. The allelic frequencies of allele 638Ser (C) and allele 638Arg (A) were 0.26 and 0.74, respectively. The significant association (P<0.05) was occurred between allele A and higher fat content, and between C allele and higher lean meat content. Our results showed no significant effect of the observed polymorphismSer638Arg on the intramuscular fat content or other indicators of carcass value.

Carcass traits and relative organ weights of growing rabbits fed graded levels of processed (ash treated and rumen liquor fermented) kola nut (Cola nitida) pod husks (PKPH) were investigated. One hundred and twenty (120) weaner rabbits of mixed breeds (New-Zealand white × Chinchilla) of equal sexes and average body weight 525.46g were randomly allotted to four (4) dietary treatments at 0 (0.00 % PKPH), 10 (10 % PKPH), 20 (20 % PKPH), and 30 % (30 % PKPH) inclusion levels and designated as diets 1, 2, 3, and 4, respectively. Each treatment group was replicated ten (10) times with three (3) rabbits per replicate and was fed ad-libitum for 56 days. The highest slaughter weight (1813.80 g/r), dressing weight (1068.70 g/r) and dressing percentage (58.54 %) recorded in rabbits fed diet 3 (20% PKPH) were similar to those fed the control diet (0 % PKPH) and diet 2 (10% PKPH) but was significantly (P<0.05) higher than those fed diet 4 (30 % PKPH). The lungs, liver, kidney, heart, and spleen of the rabbits fed dietary treatments were not significantly influenced. It was concluded that processed kolanut pod husk had no deleterious effect on carcass and relative organs weight of weaner rabbits.

Abstract. A total of 238 Pannon White growing rabbits were slaughtered at 74, 84 and 94 days of age, at an average body weight of 2.53, 2.84 and 3.15 kg, respectively. Within each age group five body weight categories were formed in such a way that the weight difference between two neighbouring groups was equally 0.3 kg. The design of the experiment permitted the separate examination of the effects exerted by age and body weight on carcass traits and on meat chemical composition of the left hind leg (HL) and that of m. Longissimus dorsi (MLD). Dressing out percentage significantly increased with the increase of age in all body weight categories, as well as with the increase of body weight. The effect of age on the ratio of the fore part of the carcass depended on the body weight: significant difference was found in lower body weight categories. The ratio of the intermediate part of the carcass was not affected by age but it increased in rabbits of higher body weight. The ratio of the hind part of the carcass increased in older animals, while it decreased in rabbits of higher body weight, and this decrease was higher in older rabbits. The ratio of the perirenal fat to reference carcass significantly decreased with age in all body weight categories, but it significantly increased in rabbits of higher body weight. With the advancement of age the moisture content of the HL increased, while that of the MLD did not change. With the increase of body weight, moisture content decreased in both the HL and in the MLD. The fat content of both HL and MLD decreased in older animals, while it increased in rabbits of higher body weight.

The objective of the research was to evaluate to effect of feeding mengkudu on performances of broilers. The research design used was completely randomized design. One hundred broilers were distributed into five treatments. The treatments were different levels of mengkudu meal (0, 0.75%, 1.5%, 2.25 % and 3%). The observed measured were feed consumption, average body weight (gain) and feed conversion. Results showed that feeding mengkudu (Morinda Citrifolia L.)  no effect significant (P>0.05) on feed consumption, average body weight and feed conversion.  In conclusion, feeding mengkudu meal up to 3% (in diet) does not negatively affect feed consumption, average body weight, and feed conversion.

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.
