Abstract Drinker devices can affect feed and water intake, which then affect performance, as well as device cleanliness, water quality and spillage. One hundred and eighteen Holstein male calves (311 ± 1.4 kg and 228 ± 0.6 d of age) were used in a randomized block design to evaluate the effect of drinker device on concentrate and water intake, performance and water spillage during the winter months. Calves were allocated in 6 pens (3 pens/treatment; 19 to 20 calves/pen) with one computerized concentrate feeder and one straw feeder. Pens were assigned to one of the two treatments: one water through (TRO, 35 cm x 35 cm, no pressure was required) or one bowl with nipple facing up (BO, bowl with a 20 cm diameter and 5-cm nipple, bite-style that was activated then animals pressed the nipple). Concentrate and water intake were recorded daily, body weight (BW), drinker device cleanliness, and water spillage (DM of bedding under the drinker) fortnightly, and water quality monthly. Data were analyzed using a mixed-effects model. Final BW, average daily gain, and concentrate intake were not affected by treatment. Apparent water intake tended (P = 0.10) to be greater in TRO (26.5 ± 0.39 L/day) than in BO (25.5 ± 0.39 L/day) and water spillage was lesser in TRO (70.3 ± 1.67 % DM) than BO (75.6 ± 1.67 % DM) pens. No differences in water quality parameters were observed despite cleanliness of TRO was lesser compared with BO devices (83.3 % vs 2.0% had presence of feed, respectively, P < 0.001). Data of the present study are promising; the bowl nipple device reduces 4% apparent water consumption and water spillage with no impairment in animal performance and improving device cleanliness. A replicate trial will be run during summer months to contrast and complete the present study results.

Abstract Antibiotics growth promoting (AGP) in animal feed has been restricted. With this, several additives have been tested in order to replace AGP and ensure intestinal health. The objective of this study was to evaluate the effects of a blend of additives on growth performance, diarrhea incidence and cecal content microbiota of nursery pigs. A total of 576 weaned pigs (6.21 ± 1.16 kg) were assigned into 4 treatments (12 replicates) in randomized block design: basal diet without additives (NC); basal diet with 120 ppm of halquinol (PC); NC + 0,05% blend of lactic acid (3,5%), benzoic acid (2,5%), flavonoids (3,5%) (B5); NC+ 0,1% of same blend (B10). The pigs were weighed 0 and 42 days into the experiment. On day 10, one animal per pen (10 replicates) was euthanized for microbiota analyses. The diarrhea incidence was calculated by the percentage of visual pens with diarrhea, by day, in the period. The growth performance was analyzed by GLIMMIX procedure and the means were compared with Tukey test (P < 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P < 0.050) by statistical program STAMP. The final weight (P = 0.010) and average daily gain (P = 0.001) of B10 and PC were higher than NC. Regarding diarrhea, it was observed that the B5 and B10 had lower incidence when compared to other groups in the total period. In the microbiome analyses, it was observed that the B5, B10, and PC groups had lower (P = 0.021) biodiversity when compared to the NC piglets. However, the B5 and B10 group had higher biodiversity when compared to the PC group. In conclusion, the supplementation with 0,1% blend of additives can be a substitute for AGP.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

ABSTRAK      Penelitian ini bertujuan untuk menyelidiki pengaruh dari pemberian pakan yang mengandung mikroenkapsulasi minyak kanola pada konsumsi, kecernaan nutrien, dan performa pertumbuhan pada domba. Lima belas domba garut jantan dengan rataan bobot badan awal 20.17 ± 4.65 kg digunakan dalam rancangan acak kelompok (RAK) pada periode pemeliharaan selama 100 hari dengan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan yang digunakan adalah P0 (kontrol / hijauan: konsentrat = 60:40), P1 (P0 mengandung 4% minyak kanola), dan P2 (P0 mengandung 4% mikroenkapsulasi minyak kanola). Hasil yang diperoleh dalam penelitian ini menunjukkan bahwa tidak ada perbedaan untuk performa, konsumsi dan kecernaan nutrien. Suplementasi minyak kanola murni maupun terenkapsulasi sebagai sumber energi dalam ransum domba, menghasilkan pertambahan bobot badan harian (PBBH) dan efisiensi penggunaan pakan yang terbaik. Proporsi asam lemak tak jenuh pada perlakuan suplementasi mikroenkapsulasi minyak kanola 8% lebih tinggi dibandingkan dengan kontrol. Perlakuan minyak kanola murni meningkatkan (P<0.05) proporsi asam stearat (C18:0) dibandingkan perlakuan lainnya. Sehingga, dapat disimpulkan bahwa suplementasi 4% mikroenkapsulasi minyak kanola di dalam ransum, selaian menghasilkan PBBH dan efisiensi pakan terbaik juga mampu melindungi asam lemak tak jenuh (ALTJ) dari proses biohidrogenasi rumen tanpa mengganggu konsumsi dan kecernaan nutrient ransum.Kata kunci: konsumsi, kecernaan, mikroenkapsulasi, minyak kanola, performaABSTRACTThe aim of this study was to investigate the effects of feeding diets with microencapsulation of canola oil on intake, nutrient apparent digestibility, and growth performance of lambs. Fifteen male garut lambs with an initial average body weight of 20.17 ± 4.65 kg were used in a randomized block design (RBD) for a 100-days feeding period with 3 treatments and 5 groups as replication. The treatments were P0 (control/forage:concentrate = 60:40), P1 (P0 contained 4% of canola oil), and P2 (P0 contained 4% of microencapsulated canola oil). The results showed that there was no difference in the growth performance, intake, and digestibility of nutrients. The best of average daily gain (ADG) and feed efficiency results from the supplementation of pure canola oil or encapsulated canola oil in diets. The proportion of unsaturated fatty acids in the supplementation of microencapsulated canola oil treatment was 8% higher than control. The treatment of canola oil supplementation increased (P<0.05) the proportion of stearic acid (C18:0) compared to other treatments. Thus, it can be concluded that supplementation of 4% of microencapsulated canola oil, besides produced the best of ADG and feed efficiency, was also able to maintain unsaturated fatty acids from the rumen biohydrogenation process without detrimental effects on nutrient intake and digestibility in lambs.    Keywords: canola oil, digestibility, intake, microencapsulation, performance

N.WATER DEFICIT APPLIED IN VEGETATIVE AND FLOWERING STAGE OF ‘TABASCO’ PEPPER IN GREENHOUSE2 ABSTRACTThe scarcity of water resources in Brazil has driven the management of demand for more efficient irrigation in farms in order to reduce water consumption and make its use more efficient. The objective of this study was to evaluate the water deficits’ effect at the vegetative and flowering stages of pepper in water use efficiency, yield and quality of pepper cv. 'Tabasco'(Capsicum frutescens) grown in a greenhouse from September 2009 to July 2010. The experiment was conducted as randomized block design with irrigation levels of 40, 60, 80 and 100% of Crop Evapotranspiration (ETc), beginning at vegetative and flowering stages. There was a significant effect of full and deficits irrigation started at vegetative and flowering stages on the fruit number per plant, and the linear model was the best fitted. The average of mass fruit per plant did not vary with the deficit, not even with the start up times. The deficit irrigation affected pepper productivity, yet it was not observed on the physical quality of fruits. The deficit irrigation (40% ETc) beginning at flowering stage allowed savings of up to 49.8% in water consumption in a cycle of 208 days after transplanting.Keywords: water stress, Capsicum frutescens, productivity and fruit quality.

Brassica Oleracea L

The low yield of cabbage in Maluku is thought to due to the lack of attention of farmers to grow to crop because so far farmers think it can only grow well and forms crops in the highlands, so no one wants to grow cabbage. This study aimed to determine the yield performance of five cabbage varieties with the use of several types of mulches and was carried out in Gemba Village, Kairatu Subdistrict, Western Seram Regency. The experimental design used was the factorial Randomized Block Design with three replications and the farmers as replications. The first factor was five varieties of cabbage (Sehati-F1, Daehnfeldt, Green Hero, Green Coronet, KK-Koss), the second factor was the type of mulch, consisting of four types, namely: without mulch (M0), black silver plastic mulch, straw mulch, and husk mulch. The data obtained were analyzed with analysis of variance and DMRT test at the level of 5% if necessary. Parameters observed included plant height at 45 days after planting, leaf number, percentage of crop formation, percentage of pest and disease attacks, crop circumference per plant at harvest, fruit weight, and yield.  The study results showed that the five varieties tested with the use of various types of mulch had the potentials to be developed in Maluku. Varieties with the highest yields and very good adaptation to lowland environments in Maluku included Sehati-F1 and KK-Cross. Pest control by using plant-based pesticides in a combination with scheduled mechanical control (yellow plates, pitfalls, and stick traps) could reduce the levels of pest and disease attacks and the crops appeared healthy for consumption. Keywords: cabbage, lowland, mulch   ABSTRAK Rendahnya produksi kubis di Maluku diduga akibat kurangnya perhatian petani untuk bertanam kubis, yang dikarenakan selama ini petani mengira kubis hanya dapat tumbuh baik dan membentuk krop di dataran tinggi, sehingga sedikit petani yang mau berusahatani kubis. Kajian ini bertujuan mengetahui keragaan hasil lima varietas kubis dengan penggunaan berbagai jenis mulsa di desa Gemba, Kecamatan Kairatu, Kabupaten Seram Bagian Barat. Rancangan percobaan yang digunakan adalah rancangan acak kelompok faktorial dengan tiga ulangan dan petani sebagai ulangan. Faktor pertama adalah lima varietas kubis (Sehati-F1, Daehnfeldt, Green hero, Green Coronet, KK-Cross); faktor kedua adalah jenis mulsa yang terdiri dari empat macam, yaitu: tanpa mulsa (M0), mulsa plastic hitam perak, mulsa jerami dan mulsa sekam. Data yang diperoleh dianalisis menggunakan analisis ragam dan uji lanjut DMRT pada taraf 5% sesuai kebutuhan. Peubah-peubah yang diamati meliputi tinggi tanaman umur 45 hari setelah tanam (hst), jumlah daun, persentase pembentukan krop, persentase serangan hama dan penyakit, lingkar buah per tanaman saat panen, bobot buah dan hasil panen. Hasil penelitian menunjukkan bahwa kelima varietas yang di uji dengan penggunaan berbagai jenis mulsa sangat berpotensi untuk dibudidayakan di Maluku berdasarkan kemampuannya membentuk krop. Varietas dengan produksi tertinggi dan beradaptasi sangat baik terhadap lingkungan dataran rendah di lokasi penelitian adalah Sehati-F1 dan KK-Cross. Penggendalian hama dengan menggunakan pestisida nabati yang dikombinasikan dengan pengendalian secara mekanis (tampan kuning, pitfoll dan sticky trap) secara terjadwal dapat menurunkan tingkat serangan hama dan penyakit, dan menghasilkan tanaman-tanaman yang sehat.

The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.
