Utilization of green algae Caulerpa racemosa as feed ingredient for tiger shrimp Penaeus monodon

ABSTRACT The study aimed to evaluate the utilization of seaweed Caulerpa racemosa as feed ingredient for tiger shrimp Penaeus monodon. This research consisted of two different stages, i.e. digestibility and growth test. Tiger shrimp with average body weight of 5.70 ± 0.42 g was reared during digestibility test. The measured parameters were total protein, calsium, magnesium, and energy digestibility. The growth test was managed by using a completely randomized design consisted of four different treatments (in triplicates) of dietary C. racemosa meal addition levels, i.e. 0 (control), 10, 20, and 30%. Tiger shrimp with an average body weight of 0.36 ± 0.02 g were cultured for 42 days in plastic containers (70×45×40 cm) with a stocking density of 15 shrimp/container. Apparent dry matter, protein, calcium, magnesium, and energy digestibilities of C. racemosa were 51.82, 88.67, 68.44, 16.39, 60.30%, respectively. The results presented that the growth performance of tiger shrimp fed with diet containing 10% of C. racemosa was not significantly different with the control (P>0.05). However, the growth performance of the shrimp fed with diet containing more than 20% of C. racemosa decreased. The enzyme activitity of superoxide dismutase (SOD) increased with the higher level of dietary addition of C. racemosa. It can be concluded that C. racemosa was possibly applied up to 10% in the feed formulation for tiger shrimp.

Penelitian ini dilakukan dengan dua tahap, yaitu uji kecernaan C. racemosa dan uji pertumbuhan udang. Udang windu yang digunakan pada uji kecernaan berbobot 5,70 ± 0,42 g. Parameter uji yang diukur meliputi kecernaan total, protein, kalsium, magnesium, dan energi. Uji pertumbuhan dilakukan menggunakan rancangan acak lengkap dengan empat perlakuan dan tiga ulangan, yaitu penggunaan tepung C. racemosa sebesar 0 (kontrol), 10, 20, dan 30%. Udang windu dengan bobot 0,36 ± 0,02 g dipelihara dalam wadah kontainer plastik ukuran 70×45×40 cm (volume air sebanyak 90 L) dengan kepadatan 15 ekor tiap wadah selama 42 hari. Hasil penelitian menunjukkan kecernaan total C. racemosa pada udang windu 51,82%, kecernaan protein 88,67%, kecernaan kalsium 68,44%, kecernaan magnesium 16,39%, dan kecernaan energi 60,30%. Penelitian tahap kedua pada kinerja pertumbuhan udang yang mengonsumsi pakan mengandung 10% C. racemosa, tidak memberikan nilai yang berbeda nyata dengan udang yang mengonsumsi pakan kontrol. Namun, kinerja pertumbuhan udang menurun setelah mengonsumsi pakan yang mengandung C. racemosa di atas 20%, sedangkan aktivitas enzim superoxide dismutase (SOD) meningkat. Dari penelitian ini dapat disimpulkan bahwa penambahan C. racemosa ke dalam formula pakan sampai 10% dapat digunakan sebagai bahan baku pakan udang windu.

Due to the mainly imported for fish feed ingredients in Indonesia, many attemps have been made to discover local potential ingredients to reduce the utilization of imported ingredients. In this experiment, the utilization of Ulva lactuca as feed ingredient for tilapia was evaluated. Experiment 1 was conducted to determine the digestibility of Ulva for tilapia. In experiment 2 and 3, Ulva was used to substitute wheat pollard of either 0, 3, 6, 9, or 12 % in the feed formulation. In experiment 2, fish with an average body weight of 4.1±0.15 g were fed on those diets, and were cultured for 55 days. To calculate the digestibity in experiment 3, Cr2O3 was added into the diet of exeriment 2; then fed on the fish with an average body weight of 19.0±0.67 g. Results showed that apparent digestibility of dry matter and crude protein of Ulva were 66.3 and 83 %, respectively. Ash content in the diet increased of 13.5% with Ulva inclusion of 12%. On the other hand, using Ulva as a substitute for pollard up to 12% was not affected the growth performance of fish. Regardless of the Ulva level in the diet, the digestibility of the diet was the same. Therefore, Ulva is a potential source of local feed ingredient for tilapia.

A study was conducted to determine the growth performance and mortality rate of Khaki Campell, Jinding and Deshi genotypes in two coastal locations of Barisal and Bhola districts of Bangladesh. Sixty-day-old ducks of 3 genotypes were randomly allocated to 3 treatments having 4 replications in each. Ducks are reared up to 150 days and at the end of experiment one male Khaki Campbell of highest live weight was selected from each replicate group. The average weekly body weight gain (g/bird) of the Khaki Campbell and Jinding were significantly (p<0.01) higher than those of the Deshi ducks. The average body weight of Khaki Campbell (1480.25g) was slightly higher than that of Jinding (1428.25g) but significantly (p<0.01) higher than that of Deshi (1140.62g) ducks at the end of the experiment. The mortality rate were significantly different (p<0.01) in various genotypes. The highest mortality was found in Deshi (30.20%) compared to Khaki Campbell (19.79%) and Jinding (17.77%). The profit margin was significantly different (p<0.01) in three genotypes. The ducks reared in Barishal performed better (p<0.01) than that from Bhola. It may be suggested from the present findings that both Khaki Campbell and Jinding ducks are performed better than Deshi in the coastal region of Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11971

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.
