<p>The most important factor in speeding up fish depends on the food given. The feed given was in the <br />form of artificial feed (pellets) because of the practicality of its availability. However, commercially <br />made feed was of course more expensive, and can pollute the air compared to natural feed which was <br />easy and can be in the surrounding environment. For this reason, it was necessary to look for natural <br />feed as an effective and efficient alternative feed to ripen the gonads of male and female swordtail. <br />The research used a completely randomized design with 4 treatments and 3 repetitions and arranged <br />randomly. Treatment by giving different natural food to the broodstock swordtail: treatment A <br />(commercial pellets), B (Daphnia/Moina), C (blood worms) and D (mosquito larvae feed). Each <br />broodstock treatment used was 27 females and 9 males (ratio 1: 3).

Permasalahan utama budidaya ikan rainbow (Melanotaenia parva) adalah sintasan larva yang masih rendah terutama pada saat terjadi peralihan makan dari cadangan kuning telur (endogenous) ke pakan eksternal (eksogenous). Pakan awal larva rainbow berupa pakan alami (plankton). Untuk menyediakan plankton dapat dilakukan melalui pemupukan kotoran ayam. Tujuan penelitian adalah penyediaan pakan alami untuk meningkatkan sintasan dan pertumbuhan larva ikan rainbow kurumoi melalui pemupukan kotoran ayam dengan dosis yang berbeda di akuarium. Akuarium yang digunakan berukuran 50 cm x 50 cm x 40 cm sebanyak 15 buah dengan volume air 40 L. Dosis pupuk kotoran ayam yang diujikan sebagai berikut: (A) kontrol (tanpa pemupukan), (B) 5 g, (C) 10 g, (D) 15 g, dan (E) 20 g per 40 L air, masing-masing perlakuan diulang tiga kali. Ikan uji yang digunakan berupa larva rainbow kurumoi yang berumur dua hari. Larva ditebar setelah 5-7 hari pemupukan dengan kepadatan sebanyak 100 ekor/wadah. Rancangan percobaan yang digunakan rancangan acak lengkap (RAL). Parameter yang diamati unsur hara pupuk, jenis dan kelimpahan plankton, sintasan larva, pertumbuhan (panjang dan bobot) larva, dan kualitas air. Hasil penelitian menunjukkan bahwa pemupukan kotoran ayam terbaik dengan dosis pupuk 20 g/40 L dengan kelimpahan plankton 58.300 ind./L; sintasan larva 84,33 ± 3,79%; dan pertumbuhan (bobot 0,048 ± 0,012 g; panjang total 1,67 ± 0,15 cm dan panjang standar 1,44 ± 0,13 cm).The main problem of rainbow aquaculture is the survival of larvae which is still low, especially at the time of the initial eating, namely the transition of food endogenous to exogenous. The initial feed of rainbow larvae is natural food (plankton). To provide natural food can be done through fertilization chicken manure. The aim of the study was the provision of natural food to improve the survival and growth of rainbow kurumoi larvae by fertilizing chicken manure with different doses in the aquarium. The container used is 50 cm x 50 cm x 40 cm aquarium with 15 pieces with 40 L water volume. The doses of chicken manure were tested as follows (A) control (without fertilization), (B) 5 g (C) 10 g, (D) 15 g and (E) 20 g per container where each treatment was repeated 3 times. The test fish used were rainbow kurumoi larvae that were around 1-2 days old. Larvae are stocked after fertilizing around 5-7 days with a density of 100 larvae/container. The experimental design was a completely randomized design (CRD). Parameters observed were fertilizer nutrients, type and abundance of plankton, larvae survival, growth (length and weight) of larvae and water quality. The results showed that fertilizing the best chicken manure with a fertilizer dose of 20 g/40 L with an abundance of plankton 58,300 ind./L, survival 84.33 ± 3.79% and growth (weight 0.048 ± 0.012 g, total length 1.67±0.15 cm and standard length 1.44 ± 0.13 cm).

The need to seek for alternative feed materials with nutritional and medicinal values to support livestock growth necessitated this study. Forty-five unsexed rabbits crosses (Chinchilla × Newzealand white) 5- 6 weeks old with average weight of 720g were used in a 10- week feeding trial to evaluate the performance of growing rabbits fed on varying levels of dried okra leaves. The rabbits were assigned into five treatment groups containing dried okra leaves (DOL) at 0%, 2.5%, 5%, 7.5% and 10% inclusion levels for dietary treatments (T1, T2, T3, T4 and T5) respectively. Each treatment consisted of 9 rabbits and replicated thrice with each replicate consisting of 3 rabbits in a completely randomized design. Data collected were subjected to one-way analysis of variance (ANOVA). Results indicated that daily feed intake was significantly (P<0.05) largest in rabbits fed 5.00% inclusion level of dried okra leaves (84.57g) and least in rabbits fed 0.00% level of inclusion of dried okra leaves (72.12g). Feed efficiency (FE) was poorest (P<0.05) in rabbits fed 10.00% DOL (0.15%) and best (0.20%) in rabbits fed 2.50% dried okra leaves. It was concluded that okra leaves can be included in diets for growing rabbits and 2.50% level of dried okra leaves inclusion is recommended for adoption by farmers to maximize profit.

desenvolvimento de obstruçõesEM GOTEJADORES e eficiÊnciado controle usando dois tipos de ácidos  Manoel Januário da Silva Júnior1; José Francismar de Medeiros21Departamento de Engenharia Rural, Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, Piracicaba, SP,  [email protected] de Ciências Ambientais, Universidade Federal Rural Do Semi-Árido,  Mossoró, RN  1 RESUMO Em irrigação localizada a qualidade da água é fundamental para o desempenho dos emissores. Uma conseqüência é a obstrução que reduz a uniformidade de emissão. Assim, os objetivos deste trabalho foram estudar o efeito da qualidade da água sobre o desenvolvimento de obstruções, bem como testar a eficiência de dois tipos de ácidos no controle dessas obstruções. O experimento foi instalado no delineamento inteiramente aleatorizado, no esquema fatorial 4x2 com duas repetições. Os tratamentos foram quatro tipos de água e dois ácidos (nítrico e clorídrico). Foi feita uma avaliação do sistema antes e outra após a acidificação. Para cada tratamento foram calculados a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. A qualidade da água de irrigação não influenciou a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. O uso de ácido nítrico e clorídrico foi eficiente no controle de obstruções. O uso do ácido clorídrico fica limitado a águas com menores teores de bicarbonatos. UNITERMOS: Gotejamento, qualidade de água, uniformidade de emissão, acidificação  SILVA JÚNIOR, M. J. da; MEDEIROS, J. F. de. DEVELOPMENT OF DRIPPER CLOGGING AND CONTROL EFFICIENCY USING TWO TYPES OF ACIDS  2 ABSTRACT In drip irrigation water quality is fundamental for emitter performance. Clogging is a consequence that reduces emission uniformity. Thus, this paper aimed to study water quality effect on the development of clogging and efficiency of acid types in clogging control. The experiment was installed in a completely randomized design with a 4x2 factorial scheme and two replications. The treatments were four types of water and two acids (nitric and hydrochloric). System evaluations were made before and after the acidification. For each treatment the following were calculated:  flow, manufacturer’s variation coefficient and emission uniformity. Water quality did not affect flow, manufacturer’s variation coefficient and emission uniformity. The use of nitric and hydrochloric acids was efficiency on clogging control. The use of hydrochloric acid is limited to waters with low bicarbonate levels. KEYWORDS: Drip irrigation, water quality, emission uniformity, acidification
