Intended Use

Abstract In the United States, substances intended for use in animal foods are generally considered to be either animal foods or animal drugs. The regulatory classification of a substance relies on its intended use. Claims for substances that are regulated as animal foods are limited to those that can be attributed to the substance’s “food” properties, which the courts in the United States have defined as being related to the provision of nutritive value, taste, or aroma or for a technical effect on the food itself. Any substance intentionally added to an animal food must be either an approved food additive as listed in part 573 in Title 21 of the Code of Federal Regulations (21 CFR 573) or a substance that is generally recognized as safe (GRAS) for an intended use, including those listed in 21 CFR 582 and 584. Also, in coordination with state feed control officials, CVM recognizes ingredients in the Official Publication of the Association of American Feed Control Officials (AAFCO) as being acceptable for use in animal foods. Everything on a pet food label must be truthful, not misleading, and appropriate for a product regulated as food. Federal regulations (21 CFR 501) require that labels include: an appropriate product name, all ingredients in descending order of predominance by weight, a statement of net quantity of contents, and the address of manufacturer or distributor. Most states have additional labeling requirements. Studies conducted for scientific research need to be evaluated to determine if the endpoints and parameters measured are also appropriate as regulatory data. Feeding studies may address target animal safety and/or utility of the substance for its intended use as a food. CVM will provide written feedback on protocols intended to address new feed ingredients.

This research aims to know the efficiency of ration use of a male Bali cattle in substitution with tofu dregs and rice bran fermentation. This research was conducted during nine weeks in Nutrition and Animal Feed Laboratory of Animal Science Department of Animal Science Faculty, Halu Oleo University, Kendari, and in Alebo Village of Konda Subdistrict of South Konawe Regency. The treatments were R0 = concentrate without fermentation-based feed (control), R1 = rice bran fermnetation-based concentrate 50%, R2 = rice bran fermnetation-based concentrate 55%, R3 = rice bran fermnetation-based concentrate 60%. The experimental design used in this study was randomly group design with 4 traetments and 3 block/group. The result of variance analysis showed that dry matter concumption was not differ markedly (p>0,05), which justifies the dry matter concumption is average from the highest to the lowest is R1 (5,143 kg/cattle/day), R0 (5,063 kg/cattle/day), R3 (4,907 kg/cattle/day) and R2 (4,905 kg/cattle/day). The substitution tofu dregs know and rice bran fermentation to 60% in ration not effect real (p>0,05) addition average daily againt of a male Bali cattle, but in quantitative R3 rations give a good response better than R0, R1 and R2 (0,542 kg/cattle/day than 0,402 kg/cattle/day, 0,411 kg/cattle/day and 0,435 kg/cattle/day). While the efficiency of used R3 rations (10,888%) higher than R2 (9,027%), R1 (8,080%) and R0 (8,075%). Conclusion that in substitution tofu dregs and rice bran fermentation to 60% in rations can give a good the efficiency of ration used of a male Bali cattle.Key Words: Bali cattle, dry matter consumption, feed efficiency, rice bran fermentationABSTRAKPenelitian ini bertujuan untuk mengetahui efisiensi penggunaan ransum sapi Bali jantan yang disuntitusi dengan ampas tahu dan dedak padi fermentasi. Penelitian ini dilaksanakan selama sembilan minggu di Laboratorium Ilmu Nutrisi dan Makanan Ternak Jurusan Peternakan Fakultas Peternakan Universitas Haluoleo Kendari dan di desa Alebo kecamatan Konda Kabupaten Konawe Selatan. Perlakuan yang dicobakan adalah R0= konsentrat berbasis pakan tanpa fermentasi (kontrol), R1= konsentrat berbasis dedak padi fermentasi 50%, R2= konsentrat berbasis dedak padi fermentasi 55% dan R3= konsentrat berbasis dedak padi fermentasi 60%. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 3 ulangan (blok/kelompok). Hasil analisis ragam menunjukkan bahwa dengan subtitusi ampas tahu dan dedak padi fermentasi sampai 60% dalam ransum tidak berpengaruh nyata (p>0,05) terhadap pertambahan bobot badan sapi Bali jantan, akan tetapi secara kuantitaif ransum R3 memberikan respon yang lebih baik dibanding R0, R1 dan R2 (0,542 kg/ekor/hari dibanding 0,402 kg/ekor/hari, 0,411 kg/ekor/hari dan 0,435 kg/ekor/hari). Konsumsi bahan kering ransum tidak berbeda nyata (p>0,05), dimana rataan konsumsi bahan kering dari yang tertinggi sampai terendah adalah R1 (5,143 kg/ekor/hari), R0 (5,063 kg/ekor/hari), R3 (4,907 kg/ekor/hari) dan R2 (4,864 kg/ekor/hari). Sedangkan efisiensi penggunaan ransum R3 (10,888%) lebih tinggi dibandingkan R2 (9,027%), R1 (8,080%) dan R0 (8,075%). Kesimpulan bahwa subtitusi dedak padi fermentasi sampai 60% dalam ransum dapat memberikan efisiensi penggunaan ransum sapi Bali jantan yang lebih baik.Kata Kunci: Sapi Bali, PBB, Konsumsi bahan kering, Efisiensi ransum, Dedak padi fermentasi

New Type

This article presents a new micro-feed mechanism, whose main transmission component is the nut–rotary ball screw pair. The screw and nut are driven by two motors, and they rotate in the same direction, with their movements enabling micro-feeding. The main contribution of the micro-feed mechanism is to avoid the inevitable low-speed nonlinear creeping phenomenon caused by the inherent properties of traditional electromechanical servo system structure, thus realizing high precision micro-feed. In this study, the motion state of the working ball is analyzed using the principle of differential geometry, the friction at the contact points is calculated, the balance equation for force and moment is established, the influences of the screw and nut on the kinematic parameters of the ball at different velocities and the differences in the motion states of the ball in different drive modes are studied, and the mechanical efficiency of the dual-driven ball screw mechanism is calculated. The potential applications of the new micro-feed mechanism and the results of numerical analysis can be applied to advanced technology fields such as robotics, suspensions, powertrain, national defense, integrated electronics, optoelectronics, medicine, and genetic engineering, so that the new system can have a lower stable speed limit and achieve precise micro-feed control.

Poor Stability

Aiming at the problem of MIG welding and considering the existing analog control wire feed system has the disadvantages of low response speed, low control accuracy and poor stability. This thesis designs a set of digital control wire feed system based on LPC2132 microprocessor and introduces the control principle of wire feed motor, CAN bus interface circuit and PID control algorithm. Under the condition of power grid voltage fluctuation and load change, we do a lot of experiments. The results show that: the wire feed change rate of designed system is very small, which not only meets the requirements of JB/T-1998.MIG/MAG arc welding standard, but also greatly improves the accuracy and stability of control system.
