Abstract

Formaldehyde is commonly used to minimize ruminal degradation of feed protein to ammonium. Its use however, could cause overprotection. An in vitro trial was designed to compare aquous extracts of Psidium guajava leaves, known to contain tannic acid, with formaldehyde solution in affecting ammoniogenesis, fermentability, anddigestibility. Peanut oil meal containing 34.9% crude protein was subjected to 7treatments: A= untreated, B=5%, C=10%, D=15% (W/V) Psidium leaf extract, E=0.5%, F=1.0%, and G=1.5% (W/V) formaldehyde solution. The treatment were applied prior to the ruminal fermentation at 2 ml/g peanut oil meal.Ammoniogenesis was significantly reduced by the formaldehydeolution to lesser extent also by the leaf extracts (A vs BCD vs EFG=6.21 vs 5.16 vs 3.23 mM ammonia/hr). The 15% leaf extracts, the 1.0% and the 1.5% formaldehyde lowered fermentability of organic matter (Avs D vs FG=18.2 vs 11.6 vs 7.27 mM VFA/hr). Allformaldehyde solution reduce either the dry matter (IVDMD) or the organic matter (IVOMD) digestibility (IVDMD : A=62.1% vs EFG=47.6%). The digestibility wasn't dramatically reduced by the leaf extracttreatments (IVDMD : A=62.1% vs CD=50.1%; IVOMD:A=58.8% vs D=46.2%). The mild effects of psidium leaf extractseventually. lead to more precipitable protein (microbial dietary/origin) (A=10.4% vs BCD =12.1% vs EFG=10.6%, suggesting that the extract has a potential to present more protein to the lower G.I. tract.

Abstract

Six groups of male chicckens were fed with three experimnental diets consisting mainly of Yellow corn-Fish meal-Soybean oil meal (YFS), Cassava-tempe meal (CT), and Cassava-tempeh-sifh meal (CTF). Main objectives of the study were : 1).To evaluate wether the CT ration could meet the energy and the protein requirements, 2). To Study the nitritive velnes of tempeh (Fermented Soybean), and 3). To compare the effects of the experimental diets on body composition. It was apparent from the experiment that the chickens on the CT diet performed poorer in terms of gain, feed consumption, feed conversion, and Nitrogen retention as well as protein deposition in the whole carcass. Animal performance was improved when the tempeh was partially substituted with fish meal (CTF diet). It seems that a diet of plant protein only was inferior to animal protein supplemented diets.

Abstract

Leucaene leucocephala has been promoted to be used as a high protein forage for ruminant. This experiment was conducted to evaluate the use of leucaena as grass substitute in sheep. Five rams were used in a 5x5 Latin square experiment from october 2 to December 18, 1982. The substitution, on dry matter basis, were A=0%, B=25%, C=50%, D=75%, and E=100%. Dry matter consumption was reduced (P/0.05) by the substitutions (A=0.361 vs BCDE=0.223 kg/d). Since the leucaena was previously wilted, the substitution increased (P/0.05) water consumption (AB=0.100 vs CDE=0.195 L/d). Digestibility of dry matter (DM), crude protein (CP), and crude fiber (CF) of the 25% substitution were the best (DM : B= 62.3 vs ACDE=51.2%; CP: B=64.0 vs ACDE=55.4%;CF:B=57.1 vs ACDE=45.4%). The 25% substitution was also the best in promoting growth (B=71.4 vs ACDE=12.9 g/d) as well as the efficiency of dry matter utilization for growth (B=0.225 vs 0.0594 g gain DM).

Abstract

In tropics climate, growth is so fast that many grasses don't maintain mineral status satisfactory for ruminants nutrition. Several publications showed that plant grown under reduced light intensity contain higher mineral than the open condition. Improving forage quality through nitrogen fertilizer has been well documented since many years ago. To get information the influence of shade and nitrogen fertilizer on the chemical composition of Brachiaria, decumbens, stapf, a split-plot experiment with shade intensity (0, 30 and 60%) as main plot and nitrogen fertilizer (0, 75 and 150 kg/ha) as sub plot was conducted on latosol soil at IPB experimental farm, Tajur-Bogor from April to August 1986.The results showed that nitrogen fertilizer affected N, P and K content significantly. There was interaction between shade and nitrogen in relation to plant N and P content. This meant that the response of the grass to the nitrogen fertilizer differed at various level of shade intensity. Application of the nitrogen fertilizer at 60% shade intensity did not affect the increase of Plant N content. Nitrogen fertilizer increased plant P content significantly at 60% shade intensity, but did not at 0 and 30%. The increased of shade intensity, raised the plant mineral content.

Abstract

The Previous in Vitro experiment indicated clearly that urea (A), peanut leaves (B), cassava leaves (C), soybean meal by product (D) and coconut oil meal (D) resulted a significant different levels of ammonia, Differences in rumen ammonia concentrations could eventually be used as an in vivo index of protein degradation value in the rumen and thus predict the amount of "by pass protein" from a protein meal.A randomized block feeding experiment was conducted to examine some nutritional aspects of five nitrogen sources using 15 local lambs.The results showed that quality of peanut leaves were good enough as protein sources for ruminant . The protein efficiency of plant feeds used in this experiment were significantly better than urea.

Abstract

twenty randomly weaning lambs with average body weight 10.46 ± 1.06 kg were randomly assigned to 5 treatment (rations). The rations are differe in level of tapioca waste or onggok (0, 10, 20, 30 and 40%) and cassava-leaf (40, 30, 20, 10 and 0%) with basic composition: rice straw (37%), coconut oil meal (20%), urea (2%) and mineral mixturer (1%). The experiment was conducted with completely randomized design. Level of tapioca waste and cassava leaf were not significantly affected Dry Matter (DM) and organic matter (OM), digestibility of dry matter and organic matter daily gain, and feed efficiency. Average daily dry matter intake and organic matter intake 318.2 gram and 287.4 gram or 55.2 g/BW0.75 kg and 47 g/BW 0.75 kg respectively;average digestibility of dry matter and organic matter : 59.71 % and 58.97 %. Average daily gain: -0.48 gram and feed efficiency : -1.13%. GE and DE intake were significantly (P/_0.05) affected by level of tapioca waste and cassava leaf in the rations; GE intake were decrease with and increase of tapioca waste of decrease of cassava leaf in the ration. Minimum GE intake (1114 kkal) were obtain with 40% tapioca waste in the ration, The maximum energy digestibility were obtain with ≥20% of tapioca waste or ≥20% of cassava leaf i.e 67.82 - 68.62. The maximum digestibility energy were obtain with 20-30% tapioca waste or 20-10% cassava leaf, i,e : 1025.06 - 1084.47 kkal/head/day.

Abstract

The purpose of this experiment were to study the optimal level of zinc in the form of zinc carbonate in the high fiber diet provided by rice bran, and to study the zinc status as well as the performance of laying hens. one control and 9 treatment groups of hisex brown laying hens, 80 in all, were fed diets with 25,50, or 75% rice bran supplemented with 25, 125, or 225 ppm zinc as zinc carbonate.Rice bran diets were isonitrogenous and isocaloric by virtue of varying levels of corn, fish meal, soybean meal and coconut oil. The experiment started at 20 weeks of age and continued 10 months. All rice bran diets produced significantly more income over feed cost than did the cornsoybean meal control. Diets with 25 or 50% rice bran and 125 ppm zinc did not differ significantly from the control in hen-day egg production. Adding 125 ppm zinc to 25 or 50% rice bran gave higher concentration in whole blood and erythrocytes than did addition of 25 ppm. The supplementation of 125 ppm zinc in 25 or 50% rice bran gave the highest zinc availability in the body. The 75% rice bran diet decreased avaibility of added zinc. Data on zinc status were obtained from randomly selected hens given labeled zinc chloride.
