Abstract The assay method is applicable to samples containing 0.00110-0.0606% carbadox (methyl 3-(2-quinoxalinylmethylene)carbazate - N1, N4-dioxide) (10–550 g/ton). Carbadox is leached from the sample with chloroform-methanol (3+1), followed by a series of solvent-solvent extractions, column chromatography, and finally the spectrophotometric measurement of the carbadox content of the final solution at 420 nm. This treatment of the feed or feed supplement sample serves to isolate the carbadox from materials that might interfere in the spectrophotometric measurement. The method of standard addition compensates for a feed or feed supplement matrix effect in the assay. A water pretreatment step improves recovery of drug from pelleted feeds. Assay results for feeds and feed supplements that were prepared under carefully controlled conditions showed good agreement between the amounts of carbadox added and found. Multiple assay values for feeds containing 0.00551% carbadox exhibited a coefficient of variation of about 5%. Assay results for commercial feed and feed supplement samples indicated that the assay method is applicable to a wide variety of feeds and feed supplements.

Penelitian evalusi nilai nutrisi pakan ayam ras petelur di Pulau Lombok telah dilakukan. Penelitian menggunakan metode survey yang berlokasi di empat Kabupaten di Pulau Lombok yaitu Kabupaten Lombok Barat, Lombok Tengah, Lombok Timur dan Lombok Utara. Pada masing-masing Kabupaten diambil 4 peternak ayam ras sebagai sampel  dan dianalisa di Laboratorium Nutrisi Makanan Ternak Fakultas Peternakan Universitas Mataram. Data dianalisa dan ditabulasi kemudian dipresentasikan dalam bentuk diskriptif. Hasil penelitian menunjukkan bahwa semua peternak ayam ras petelur menggunakan jagung, dedak padi, dan konsentrat sebagai ransum dasar berturut-turut sebesar 43 %±8.13, 22%±3.93, dan 33%±4,83. Campuran pakan tersebut mengandungan protein sebesar 17.21% ±1.23, energi metabolis 2753 ± 63.78, lemak kasar dan serat kasar sebesar 4.03% ±0,2  dan 6.29 % ±0.46, Ca dan P sebesar 3.61% ±0.53 dan 0.51% ±0.03.

Using surveys methode in four locations in Lombok Island i.e. West Lombok, Central Lombok, East Lombok, and North Lombok and four farmers sample of each. Data was analyzed in loboratorium animal nutrition Faculty of Animal Husbandry Mataram University. Data was analized and tabulated and than descriptive presented. The result show that, all of the farmer in Lombok Island use rice bran, maize, and commercial feed as elementary ration with 43%±8.13, 22%±3.93, and 33%±4.83 respectively, in addition, all farmers use feed supplements such as vitamins or mineral. Nutrition value of ration are 17.21% ±1.23 protein, 2753±63.78 metabolizeble energy, 4.03% ±0,2  extract ether and  6.29%±0,46 fibers, Ca and P are 3.61 % ±0.53 and 0.51%±0.03. Average eggs production, feed consumption, egg weight, shell thickness, and Haught Unit (HU) are 56%±8.68, 114±31,25 g.ekor-1.hari-1. 61.71±2.49 g, 0.39±0.03 mm, and 90.16 ±4.33. It can be concluded that nutrient composition of laying hens in Lombok Island according to Indonesian Standard Feed, however, eggs production and quality still low.Key words: Vitamine, concentrate, nutrient

This study was intended to determine the free testosterone levels and sperm quality of local rabbit that was given commercial feed supplemented cod fish liver oil.  The experiment design that was used in this research was Complete Random Design (CRD) with four experiments of feed, i.e. commercial feed without cod fish liver oil (R-0) as control, commercial feed + 1,5% cod fish liver oil (R-1), commercial feed + cod fish liver oil 3% (R-2), commercial feed + cod fish liver oil 4,5% (R-3). The each experiment included eight rabbits and feed experiment was given starting by 13 weeks to 26 weeks years old. The variable that observed was free testosterone level and sperm quality of local rabbit. The data that was obtained to be analyzed with One Way Anova and if its contrast was done more test with Duncan’s Multiple Range Test (DMRT). The result of this research was to show that supplementation of cod fish liver oil in commercial feed was to show the result that a real distinction of (P<0, 05) towards free testosterone level and sperm quality of local rabbit.

Objectives The aim of this study was to analyze iron, copper and zinc concentrations in commercial foods and compare among food formats (dry, canned, raw), foods marketed by age category (adult 1+ years and senior 7+ years) and foods intended for adult maintenance vs all life stages. Methods In total, 112 commercial non-therapeutic food products marketed for healthy adult and senior cats were purchased in the USA. Foods were analyzed for their proximate composition. Trace mineral concentrations were measured using inductively coupled argon plasma–optical emission spectroscopy and described on a calculated metabolizable energy basis using standard modified Atwater values. Results Measured iron (median 58.4 mg/1000 kcal [range 15.7–379.0]), copper (median 5.6 mg/1000 kcal [range 0.8–13.3]) and zinc (median 47.6 mg/1000 kcal [range 7.6–128.1]) concentrations were highly variable among cat foods. When all food products – regardless of their nutritional adequacy substantiation method – were compared with the Association of American Feed Control Officials regulatory minimums, 13/112 food products had a mineral deficiency, of which a majority (n = 11/13) were raw food products. Raw foods had significantly lower trace mineral concentrations compared with dry food products and, except for copper, canned food products. Cat foods marketed for senior cats had higher iron ( P = 0.019) and zinc ( P <0.0001) concentrations than foods marketed for adult cats. Foods intended for adult maintenance had higher iron ( P = 0.003) and zinc concentrations than foods intended for all life stages ( P <0.0001). Conclusions and relevance Iron, copper and zinc concentrations in commercial non-therapeutic foods for adult and senior cats are highly variable. A minority of foods – mainly raw food products – were deficient in these minerals. It is unknown if some foods with high trace mineral concentrations could have adverse effects as studies are needed to establish safe upper limits for dietary intake of trace minerals in healthy cats.

Experimental Group

The research studied the effects of dietary supplementation with Camelina sativa fresh forage on the chemical and fatty acid composition of milk and Caciotta cheese, and its sensory properties. Twenty Ionica goats were randomly assigned to the following two groups (n = 10): the control received a traditional forage mixture (Avena sativa, 70%; Vicia sativa, 20%; Trifolium spp., 10%), while the experimental group was given Camelina sativa fresh forage (CAM). All of the dams grazed on pasture and received a commercial feed (500 g/head/day) at housing. The milk from the CAM group showed a higher (p < 0.05) content of dry matter, fat, lactose and concentrations of C6:0, C11:0, C14:0, C18:2 n-6, CLA and PUFA, while lower (p < 0.05) amounts of C12:0, C18:0 and saturated long chain FA (SLCFA). The Caciotta cheese from the CAM group showed a greater (p < 0.05) content of n-6 FA and n-6/n-3 ratio, although close to four, thus resulting adequate under the nutritional point of view. The overall liking, odour, taste, hardness, solubility and “goaty” flavour were better (p < 0.05) in the CAM cheeses. Further investigation would be advisable in order to evaluate the effect of feeding Camelina forage obtained from different phenological stages, and the application of ensiling techniques.
