Abstract

An excellent animal performance has to be supported by feed availability. Quality and quantity of forages are important factors. The existence of weeds significantly decreases rate of production and quality of herbage. Physically weed control by defoliation could be expected to sustain quality and production of herbage, and able to control weeds expansion. The aims of the study were to find the effect of interval defoliation of B. humidicola that was invaded by C. odorata and its effect on production, crude protein, phosphor, calcium contents of B. humidicola herbage, production and population dynamic of C. odorata. The treatments were nine different planting methods and different defoliation intervals, namely: B. humidicola was defoliated every 30 days without C. odorata (P1); B. humidicola was defoliated every 60 days without C. odorata (P2); B. humidicola was defoliated every 90 days without C. odorata (P3); B. humidicola were defoliated every 30 days, C. odorata were not defoliated (P4); B. humidicola were defoliated every 60 days, C. odorata were not defoliated (P5); B. humidicola were defoliated every 30 days, C. odorata were not defoliated (P6); B. humidicola and C. odorata were defoliated every 30 days (P7); B. humidicola and C. odorata, were defoliated every 60 days (P8); B. humidicola and C. odorata were defoliated every 90 days (P9). Two experiment designs namely Completely Randomized Block Design and Split Plot Design in Time were used in the field experiments. The result of the experiments showed that dry matter production of B. humidicola which were defoliated every 90 days were not significantly different than those defoliated every 60 days, but it was significantly higher than those defoliated every 30 days. Crude protein, phosphor, and calcium content of herbage which were defoliated every 30 days were significantly higher than those defoliated every 60 days and 90 days. Present and defoliation of C. odorata did not affect the herbage production, and phosphor content, but it decreased crude protein and calcium content of B. humidicola herbage. Keywords: production, quality, herbage, defoliation interval

Abstract

Carcass and non-carcass production of Priangan and Fat Tail sheep were studied at the Department of Animal Production, Faculty of Animal Science, Bogor Agricultural University. Six male Priangan and six male Fat Tailed lambs were killed at 17.5 kg slaughter weight. A similar number of both breeds were also killed at 25.0 kg. Priangan and Fat Tail of 18.483 ± 0,160 and of 18.583 ± 0.262 kg body weight were fasted 24 hours (water was allowed) and fasted body weight (slaughter weight) were 17.600 ± 0.089 and 17.490 ± 0.020 kg, respectively. Similarly, Priangan and Fat Tail of 26.190 ± 0.207 and 26.283 ± 0.349 kg were also fasted at the same treatment and slaughter weights were 24.914 + 0.183 and 24.890 ± 0.114 kg. Before killing, they were reared on a pelleted ration containing 73.3% TDN and 16% crude protein (100% dry matter basis). Those animals were killed and dissected. The results showed that there were no significant differences in the weight of carcass, organs and offals, except in the weight of head and tail at 17.5 kg (P < 0.05) and at 25.0 kg (P < 0.01). At 17,5 kg slaughter weight, Priangan (17600 ± 89 g) produced 47.10% carcass, 11.14% head and shank, 6.67% skin, 14.38% offals, 4.84% blood and 12.71% gut content; Fat Tail (17490 ± 20 g) produced 48.76% carcass, 9.20% head and shank, 7.00% skin, 13.38% offals, 4.08% blood and 11.99% gut content. At 25.0 kg slaughter weight, Priangan (24917 ± 183 g) produced 48.70% carcass, 10.14% head and shank, 6.90% skin, 12.90 offals, 5.03% blood and 12.12% gut content. Fat Tail produced 52.39% carcass, 8.39% head and shank, 7.00% skin, 13.11% offals, 4.19% blood and 10.61% gut content. Key words: Priangan sheep, carcass

Abstract

This research was conducted to investigate physical, organoleptical and microbiological characteristics of dadih from cow milk fermented with different combinations of probiotic starter bacteria and stored at low temperature. The concentration of starter used to make dadih was 3% with equal comparison between starters. The combinations of probiotic starter bacteria were (L. plantarum (A1), L. plantarum + L. acidophilus (A2), L. plantarum + B. bifidum (A3) and L. plantarum + L. acidophilus + B. bifidum (A4)) and stored at low temperatures (refrigerator) for 0, 7 and 14 days. The observed variables were viscosity, total lactic acid bacteria, total Bifidobacterium bifidum and organoleptic properties (color, aroma, taste and firmness). The result showed that combinations of probiotic starter bacteria did not affect significantly (P > 0.05) viscosity and total Bificobacterium bifidum of dadih at H-0 (before storage), but affect significantly (P < 0.05) total lactic acid bacteria. The characteristics of dadih during 14 days of storage in low temperature showed that combinations of starter did not significantly affect viscosity but storage time affect significantly (P < 0.05). Total Bificobacterium bifidum was not affected significantly by either starter combination or storage time.Total lactic acid bacteria was significantly affected (P < 0.05) by storage time and very significantly affected (P < 0.01) by starter combinations. A4 starter combination (L. plantarum + L. acidophilus + B. bifidum) has the most preference modus value for firmness, color, flavor and aroma according to panelist test result. Among those four organoleptic parameters, only aroma was affected significantly by starter combination. Key words: dadih, cow milk, probiotic, lactic acid bacteria, characteristic

Abstract

The purpose of this experiment was to study the effect of banana leaf meal in diet (0-3 weeks) on compensatory growth of broiler (3-5 weeks). One hundred and twenty day old chick were fed one of three different treatment : P1 used 0 % banana leaf meal from 0-5 weeks (R1), P2 used 5 % banana leaf meal (R2) from 0-3 weeks and R1diet from 3-5 weeks and P3 used 10 % banana leaf meal (R3) from 0-3 weeks and R1 diet from 3-5 weeks. Each of experiment diets contained of 2900 kcal/kg metabolizable energy and 21% crude protein. Completely Randomized Design was used in this experiment. The results showed that feeding with banana leaf meal at 0-3 weeks significantly (P < 0.01) reduced feed intake, and body weight gain (P < 0.05). Recovery periods (3-5 weeks) did not show the compensatory growth because of significantly reduced (P < 0.05) feed intake and body weight gain. Conclusion showed that effect of banana leaf meal in diet (0-3 weeks) on compensatory growth of broiler (3-5 weeks) could not maximize final body weight. Key words: banana leaf meal, compensatory growth, broiler

Abstract

Corn is used as foodstuff and industrially utilized feed as a potential ingredient in animal ration. Green forage, baby corn and its cobs are used also as ruminants feed. Application of Chromolaena odorata on latosol as mulch material is expected to improve corn production by contributing organic nutrition. The objectives of this research were to recognize the effect of Chromolaena odorata on production and quality of green forage of high density corn, and to observe the contribution of phosphorous mineral from decomposition of Chromolaena odorata in the ground. This research was divided into two steps of experiment. The first experiment, consisted of two levels of treatments, i.e.: with and without Chromolaena odorata (12 ton/ha). The plants were fertilized with 60 kg K/ha and 225 kg N/ha. Plant was harvested at 40 days after planting. In the second experiment, corns were cultivated in the same area and the application of mulch (12 ton/ha) and P (60 kg/ha). Mulch increased significantly vertical height but there was no effect on production of green forage, mineral content in crop and uptake of P and N. In the second experiment, mulch addition improved vertical height of the crop, fresh and dry weight of green forage, content of P and N on the tissues of crop and also uptake of P and N between two treatments were not significant. Application of Chromolaena odorata mulch (2x12 ton/ha) was similar as the addition of P anorganic (60 kg/ha) in improving growth, production and quality of green forage of corn. In this research, the mulch improved the content of mineral P and N in the soil. Key words: mulch, Chromolaena odorata, mineral P, corn

Abstract

High content of Al on the soil maybe harmful (toxic for plant). Red and yellow podzolic soil was marginal land that characterized by high Al content. Azospirillum is free living N fixing bacteria that can be associated with grass. This research was conducted to find the best yield of grass planted on the soil inoculated with Azospirillum. The research consisted of some steps; 1) soil sampling 2) laboratory research: bacterial isolation, isolate selection, standardized of population, content of IAA 3) pod experiment. Pod experiment in the glass house was designed in completely randomized design, that consisted of six treatments. The variables observed were dry mass production of shoot and root, nitrogen content of shoot and root, and nitrogen absorption. Four best isolates chosen were; SM Setaria, OBIS/BD, PO2 and PM2. Azospirillum isolates enhanced shoot and root production, nitrogen content and N total absorption of tolerance one (S. splendida). The susceptible (C. gayana), Azospirillum significantly enhanced shoot and root nitrogen content, but did not affect the growth, production and N total absorption. Root growth that was inhibited by Al toxicity, decreased the symbiotic capability of nitrogen fixing bacteria. PM2 isolate showed the best effect on production and quality of S. splendida as well as on C. gayana. This isolate will be used for future research. PM2 produces 6.4 ppm Indole Acetic Acid that promoted root growth. Key words: Azospirillum sp, Setaria splendida, Chloris gayana, Al toxicity

Abstract

The aim of this study was to evaluate the effect of superovulation treatment using combination of CIDR, FSH and hCG in beef cattle as donor embryos using MOET programme. All animals had been palpated to evaluated the ovary status and normal cows were used as donor and synchronized with CIDR (Eazy BreedTM). At day 10 of oestrus cycle, cows were divided into two groups, first group: cows were injected intramuscularly with FSH (Antrin) 40 IU per cow with decreasing doses (for 4 days) and second group cows were treated the same way but at day 5 after FSH injection, they were injected intramuscularly with 1,500 IU hCG (Chorulon). Embryo collection was done at day 7 after Artificial Insemination (AI). Average number of corpora lutea (CL) in animals that superovulated with CIDR, FSH and hCG was significantly higher (P < 0.05) compared to animals treated with CIDR and FSH only (5.52). Average number of embryo collection and number of transferable embryos were also higher in group treated with hCG (6.00 vs 5.44) compared with those treated without hCG (4.33 vs 3.17). The conclusion is hCG superovulation injection with CIDR and FSH can increase the respon of superovulation. Key words : superovulation, CIDR, FSH, hCG, beef cattle

Abstract

Fibrous feeds vary in their physical properties. The experiment aimed to clarify the effect of physical properties of fibrous component in rations on feed intake and nutrient digestibility in goats. Rations were composed of 50% fibrous feed and 50% concentrate. The fibrous feed as treatments were as follows: napier grass (RG), rice straw (JP), cocoa pod (KC), mixed rice straw and coffee husk (JK), mixed napier grass, rice straw, coffee husk, and cocoa pod (CP). Rations were offered to four groups of 20 Etawah-grade goats weighing of 13.50±2.14 kg in a randomized block design. Physical properties of the fibrous components of ration and faeces, nutrients intake and digestibility and daily life weight gain were evaluated. Analysis of variance and correlation were applied to analyze data. Dry matter intake varied from 298-440 g/day. Goats offered KC ration had the highest intake. Low feed intake was associated with the low density of the fibrous component. Dietary fat digestibility decreased when the fibrous feed component had low capacity of oil adsorption. Young goats had life weight gain of 50-136 g/day, TDN requirement for maintenance and 50 g daily gain of 63.4 g and 131 g TDN, respectively. The results indicated that physical properties of fibrous component in the rations influenced dry matter intake and nutrients digestibility in growing goats. Key words : physical properties, intake, nutrient, digestibility, goat
