Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency.Methods: Animals (n = 270) were assigned to one of five treatments at 28 d. Low WW pigs (<6 kg) were either weaned and offered a special dietary regime recommended for low WW pigs (WEAN) or placed on a nurse sow (NURSE) and weaned at 49 d. Normal WW pigs (9 kg) (NORM) were also weaned at 28 d. After weaning, NORM and NURSE pigs were offered either a ‘high’ (4 kg/pig of starter 1 diet followed by 8 kg/pig of starter 2 diet) or ‘low’ (8 kg/pig of starter 2 diet) starter diet allowance in a 2×2 factorial arrangement. A typical grower diet was then offered, followed by a typical finisher diet until 147 d of age.Results: NORM pigs where heavier throughout their life compared to NURSE pigs (91.4 kg vs 76.2 kg at 147 d; p<0.001). WEAN pigs were heavier at 70 d compared to NURSE pigs (23.9 kg vs 21.0 kg; p<0.001), but there was no significant difference at 147 d between NURSE and WEAN treatments. NURSE pigs had reduced feed intake throughout the finishing period (1.6 kg/d; p<0.001) compared to WEAN (2.0 kg/d) and NORM (1.9 kg/d) pigs. Feed conversion ratio (FCR) of NURSE (2.20) was lower than NORM and WEAN during the finishing period (2.40 and 2.79, respectively).Conclusion: Extended (up to 49 d) nursing for low WW pigs resulted in improved FCR during the finishing period, but no overall improvement in growth rate compared to low WW pigs weaned at 28 d and offered a specialised starter regime. Normal WW pigs where significantly heavier than low WW pigs throughout the study.

Ikan baung (Hemibagrus nemurus) merupakan salah satu ikan asli yang terdapat di Indonesia. Ikan ini memiliki harga lebih tinggi dibandingkan beberapa jenis ikan lainnya yang telah populer di kalangan konsumen. Saat ini, ikan ini sedang pada program domestikasi dimana informasi mengenai lokasi yang sesuai untuk pemeliharaan ikan baung belum banyak dipelajari. Penelitian ini bertujuan untuk mengevaluasi pertumbuhan benih ikan baung pada dua lokasi pemeliharaan dengan ketinggian yang berbeda. Penelitian dilakukan pada lokasi dengan ketinggian rendah (< 200 m dpl) di daerah Cijengkol dan lokasi dengan ketinggian sedang (200-400 m dpl) di daerah Maleber, Jawa Barat. Benih ikan baung hasil domestikasi (bobot: 21,62 ± 0,57 g) ditebar pada tiga buah jaring masing-masing berukuran 2 m x 2 m x 1 m dengan padat tebar 15 ekor/m3 di kolam berukuran 40 m x 20 m yang terletak pada masing-masing lokasi pengujian. Ikan diberi makan dengan pakan komersial (30% protein) sebanyak 5% biomassa per hari dengan frekuensi pemberian pakan dua kali sehari selama 180 hari masa pemeliharaan. Kualitas air yang diamati meliputi suhu, oksigen terlarut, dan pH. Parameter yang diukur yaitu pertambahan panjang, pertambahan bobot, laju pertumbuhan spesifik, rata-rata pertumbuhan harian, pertambahan biomassa, rasio konversi pakan, dan sintasan. Hasil penelitian menunjukkan bahwa benih ikan baung yang dipelihara pada ketinggian < 200 m dpl menunjukkan pertambahan bobot dan biomassa yang lebih baik (30,93 ± 2,29 g dan 7,44 ± 0,79 kg) dibandingkan jika dipelihara pada ketinggian 200-400 m dpl (22,32 ± 1,26 g dan 5,97 ± 0,65 kg) (P<0,05). Rasio konversi pakan pada ikan baung yang dipelihara pada dataran rendah lebih rendah (2,37) dibandingkan jika dipelihara pada dataran sedang (2,68). Suhu air pada ketinggian < 200 m dpl lebih tinggi dibandingkan pada ketinggian 200-400 m dpl (P<0,05). Benih ikan baung tumbuh lebih optimal jika dipelihara di daerah dataran rendah, karena pada daerah tersebut memiliki suhu lebih tinggi yang dapat memengaruhi laju pertumbuhan.Asian redtail catfish (Hemibagrus nemurus) is one of Indonesia’s native fish species. This species has a higher commercial value compared to some other fish species already popular among consumers. The fish is currently under a domestication program which information regarding the suitable rearing location has yet to be established. This research was aimed to study the growth of Asian redtail catfish fingerlings reared in two different-altitude locations. The evaluate was conducted at low-altitude location (< 200 m above sea level) in Cijengkol area and mid-altitude location (200-400 m above sea level) in Maleber area, West Java. In each location, the fingerlings of domesticated Asian redtail catfish (weight: 21.62 ± 0.57 g) were stocked in three net cages sized 2 m x 2 m x 1 m in a pond (40 m x 20 m) with a stocking density of 15 fish/m3 per net cage. The fingerlings were fed with commercial feed (30% protein) of 5% fish biomass per day with feeding frequency twice a day for the period of 180 days. The water quality parameters observed were temperature, dissolved oxygen, and pH. The measured experimental parameters were length gain, weight gain, specific growth rate, average daily growth, biomass gain, feed conversion ratio, and survival rate. The results showed that the fish reared at <200 m above sea level had better weight and biomass gains (30.93 ± 2.29 g and 7.44 ± 0.79 kg) than that of the fish reared at 200-400 m above sea level (22.32 ± 1.26 g and 5.97 ± 0.65 kg) (P<0.05). The feed conversion ratio of fingerlings reared at the low-altitude location was lower (2.37) than those of the mid-altitude location (2.68).The water temperature at < 200 m above sea level was significantly higher than that of 200-400 m above sea level (P<0.05). The growth of Asian redtail catfish fingerlings is more optimal in lowland areas due to higher water temperature accelerating the fish growth rate.

Frekuensi pemberian pakan merupakan faktor yang penting karena berpengaruh terhadap pertumbuhan dan berperanan penting dalam efektivitas penggunaan pakan. Penelitian ini bertujuan untuk mengetahui frekuensi pemberian pakan yang tepat pada pemeliharaan yuwana kakap merah. Hewan uji yang digunakan untuk penelitian adalah yuwana kakap merah, Lutjanus argentimaculatus umur 56 hari dengan bobot awal 0,18 ± 0,03 g sebanyak 180 ekor. Penelitian dilakukan menggunakan 12 tangki polyethylene volume 60 L. Rancangan penelitian adalah acak lengkap dengan empat perlakuan dan tiga ulangan. Perlakuan yang diujikan dalam penelitian ini adalah perbedaan frekuensi pemberian pakan, yaitu (A) 2 kali sehari (08:00, 14:00); (B) 4 kali sehari (08:00, 11:00, 14:00, 17:00); (C) 6 kali sehari (08:00, 10:00, 12:00, 14:00, 16:00, 18:00); dan (D) 8 kali sehari (08:00, 09:30, 11:00, 12:30, 14:00, 15:30, 17:00, 18:30). Hasil penelitian menunjukkan bahwa perbedaan frekuensi pemberian pakan berpengaruh nyata (P<0,05) terhadap pertumbuhan bobot dan laju pertumbuhan bobot harian yuwana kakap merah serta nisbah konversi pakan dan efisiensi pakan, namun tidak berbeda nyata terhadap sintasan (P>0,05). Frekuensi pemberian pakan delapan kali sehari dengan interval waktu setiap 1,5 jam menghasilkan pertumbuhan bobot dan laju pertumbuhan harian yuwana kakap merah yang paling besar serta nisbah konversi pakan yang terendah dan efisiensi pakan yang tertinggi.Feeding frequency was an important factor that gave the influence to growth and also for effectiveness using the feed. This research was aimed to get the information about effective feeding frequency on rearing of mangrove snapper Lutjanus argentimaculatus juvenile. This research was using12 polyethylene tank of 60 L in volume and 180 juvenile of 56 days old with 0.18 ± 0.03 grams of body weight. Complete random design with four treatments and three replicates was used in this research. The treatment was different feeding frequency, i.e.: (A) 2 times perday (08:00, 14:00); (B) 4 times perday (08:00, 11:00, 14:00, 17:00); 6 times perday (08:00, 10:00, 12:00, 14:00, 16:00, 18:00); dan 8 times perday (08:00, 09:30, 11:00, 12:30, 14:00, 15:30, 17:00, 18:30). The result indicated that different feeding frequency was significant to body weight, body weight gain and daily growth rate of mangrove snapper juvenile, also to feed conversion ratio and feeding efficiency, but not significant to survival rate. Feeding frequency 8 times perday with interval 1.5 hours gave the biggest of body weight, body weight gain and daily growth rate, the lowest of feed conversion ratio and the highest of feeding efficiency.

An experiment was designed and carried out to assess the survival, growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Heterobranchus bidorsalis fingerlings fed graded levels of toasted Lima beans seed (Phaseolus lunatus) meal based diets with the aim of establishing the best inclusion level of Lima beans seed meal. One hundred (100) fingerlings with an initial mean weight of 2.5± 0.5g were allotted at random to five treatments in triplicate groups with each treatment tank having five fingerlings and were fed with the compounded diets. The toasted Lima beans seed meal was used to replace soybean meal in the diets in the following proportions: Diet I (0%), diet II (25%), diet III (50%), diet IV (75%) and diet V (100%). At the end of the feeding trials that lasted for 70 days, At the end of the experiment, the Specific growth rate showed no significant difference (P >0.05) among all treatments. Treatment III (3.250) had the highest specific growth rate and Treatment II (2.083) had the lowest value. Relative weight gain was highest in treatment V (20.53) with 100% lima beans and lowest in treatment II (16.95) with 25% lima beans diet inclusion level. Treatment I and IV had no significant difference (P >0.05) but these treatments had a significant difference (P<0.05) with treatments II, III and V also treatment II, III, and V are significantly different (P<0.05) from each other. There was no significant different (p>0.05) in the feed conversion ratio of treatment II, III, IV. There was also no significant difference (p> 0.05) in the feed conversion ratio of treatment I and V. Treatment II, III and IV showed a significant difference (P< 0.05) in the feed conversion ratio with treatment I and V. FCR was highest in treatment II (1.383) and lowest in treatment IV (1.162). Treatment V had the highest feed intake with value 3.775. Treatment I, II, III, IV and V had no significant difference (P> 0.05). Treatment I had the lowest feed intake with value (3.246). Protein efficiency ratio showed no significant differences among all treatment. PER was highest in treatment V (6.346) and lowest in treatment III (5.346). The survival rate was slightly different but not as a result of the feed consumed. Based on the findings in this study, it is therefore recommended that 75% inclusion level of Lima beans meal should be adopted in the formulation of feed for Heterobranchus bidorsalis.
