Evaluation of cassava leaf meal (Manihot esculenta Crantz) in feed with enzymes supplementation on broiler performances

The research aimed to evaluate the effect of cassava leaf meal with enzymes supplementation in the feed on the performance of broiler. The research used factorial completly randomized design 2x3 on 240 Cobb-strain broilers. There were 6 treatments with 2 factors is used cassava leaf meal (CLM) and enzymes (non-starch polysaccharides and protease) with each dose 250 g/ton feed, i.e. P1: basal ration, P2: basal ration with enzymes, P3: ration with 1.5% CLM, P4: ration with 1.5% CLM and enzymes, P5: ration with 3.0% CLM, P6: ration with 3.0% CLM and enzymes. The variables analyzed were body weight, body weight gain, feed intake, feed conversion ratio, and mortality. The data obtained were analyzed by analysis of variance (ANOVA) and if the results indicated significantly different, then the post-hoc test conducted. The results showed that there was an interaction between CLM and enzymes on the feed conversion ratio (P < 0.05). The addition enzymes can decrease feed conversion ratio (from 1.91 to 1.74) siginificantly (P < 0.05). Addition CLM to a level of 3.0% did not interfere with performance. Enzymes can offset the detrimental effect caused by the use cassava leaf meal in the feed.

Effect of Adding Cassava Peel and Lactic Acid Bacteria as a Feed Additive to the Weight of Immune Organs of Super Native Chicken

This study aims to evaluate the use of cassava peels added with lactic acid bacteria on the immune organ weight of super native chickens. The material used in this study was 144 Day Old Chick (DOC) super unsex native chicken with an average body weight of 34 ± 3,14 gram. The research design used was a completely randomized design (CRD) with a dose of liquid feed additive in the form of a combination of cassava peel flour and lactic acid bacteria mixed with rations. The treatments in this study included T0: basal ration, T1 (basal ration + 10% feed additive ml/kg), T2 (basal ration + 15% feed additive ml/kg) and T3 (basal ration + 20% feed additive ml/kg). The parameters observed were body weight, the relative weight of lymph, thymus, and bursa Fabricius superficial chicken stock exchange. The result showed that the combination of cassava peel and lactic acid bacteria had no significant effect (P>0.05) on body weight, the relative weight of the lymph organs, thymus, and bursa Fabricius of super native chickens. This research concludes that the combination of cassava peel and lactic acid bacteria as a feed additive can maintain chickens' health by not increasing the relative weight of the super native chicken immune organs to the level of 200 ml/kg.

Effects of rations containing leubiem fish (Chanthidermis maculatus) waste and phytogenic suplementation on local ducks performance in the starter phase

This study aims to examine the potential use of leubiem fish (Chanthidermis maculatus) waste and phytogenic supplementation on ration, in order to increase the performance of local ducks in the starter phase. This study used 100 local ducks aged 1 week old, and maintained them until 8 weeks old. The ducks were placed in 5 treatments and 4 replications groups (5 ducks / repetition). The study was conducted experimentally, using a Completely Randomized Design (CRD), consisting of 5 ration treatments, including: R1 (control); R2 (basal ration containing leubiem fish skin flour 10% + phytogenic 0.5%); R3 (basal ration containing leubiem fish head flour 10% + phytogenic 0.5%); R4 (basal ration containing leubiem fish bone flour 10% + phytogenic 0.5%) and R5 (basal ration containing leubiem fish gill flour + phytogenic 0.5%). Observed variables were feed consumption, body weight gain, final weight, feed conversion, and local duck mortality in the starter phase. The data obtained were both analyzed using Analysis of Variance (ANOVA) and Duncan’s multiple range test. The results showed that the use of leubiem fish waste and phytogenic supplementation in the ration both increased the performance of local ducks in the starter phase and had a significant effect (p <0.05) on ration consumption, weight gain, and final weight. However, they had no significant effect on feed conversion and local duck mortality in the starter phase. It was concluded that the use of leubiem fish (10% bone meal) and phytogenic supplementation 0.5% in the ration was able to increase body weight gain, and the final weight of the starter phase local ducks (aged 1-8 weeks).

This study aims to evaluate the milk lactose, specific gravity, and mineral of Etawa Crossbreed Dairy Goat (ECDG) fed with palm kernel cake-based concentrate (PKCC), tithonia (Tithonia diversifolia), sweet potato leaves, (Ipomoea batatas L.), and Gamal (Gliricidia sepium) as a source of roughage. The design of the experiment used was a completely randomized design (CRD) with four treatment rations and four replications. Treatment formulations are as follow A). 100% basal ration (BR); B). 50% BR + 50% Concentrate Based Palm Kernel Cake (CPKC) + tithonia; C). 50% BR+ % CPKCC + sweet potato leaves; D).50% BR + 50% CPKC + Gamal (Gliricidia sepium). The ratio of concentrate and roughage is 50:50. The concentrate ratio consists of 30% palm kernel cake, 40% tofu waste, 20% rice bran, 9 % corn, and 1% mineral. The parameters were milk lactose, specific gravity, and mineral of milk. Data were analysed by Analysis of Varian (ANOVA) and DMRT (Duncans Multiple Range Test) according to Steel and Torrie (2002). The results showed that the treatment had no significant effect (P> 0.05) on lactose, specific gravity, and mineral of milk. From this study, it can be concluded that the use of PKC, titonia, sweet potato, and gamal can replace basal ration without affecting the quality of milk (lactose, specific grafity and mineral)

Effects of alfalfa (Medicago sativa L.) supplementation in the diet on the growth, small intestinal histomorphology, and digestibility of hybrid ducks

Background and Aim: Feed plays the most important role in supporting livestock productivity. There is a need for studies on the nutrient levels in feed absorbed by the body of livestock. The aim of this study was to investigate the effects of alfalfa (Medicago sativa L.) supplementation in feed on growth, small intestinal histomorphology, and digestibility in hybrid ducks. Materials and Methods: The study was conducted in vivo using 75 hybrid ducks, with three treatments and five replications. Each replication consisted of five ducks. The treatments were: T0=basal ration without any alfalfa supplementation; T1=basal ration+3% fresh alfalfa supplementation; and T2=basal ration+6% fresh alfalfa supplementation. Fresh alfalfa was quantified on the basis of dry matter content. Drinking water was provided ad libitum. The observed variables were growth performance, measured in terms of feed consumption, body weight gain, and feed conversion ratio; duodenum histomorphology, measured in terms of villus height, villus width, and crypt depth; digestibility, measured in terms of dry matter digestibility; and organic matter, crude protein, and crude fiber concentrations. The data were analyzed using variance analysis with a completely randomized design of one-way pattern with Statistical Product for Service Solution application of version 22. The data with significant differences were further analyzed using Duncan's new multiple range rest. Results: The results of the study showed that 3% alfalfa supplementation increased feed consumption and body weight gain of the hybrid ducks at 35 days of age compared with 0% and 6% supplementation. Furthermore, 3% alfalfa supplementation presented the best result in terms of villus height and duodenal crypt depth. Meanwhile, 6% alfalfa supplementation decreased nutrient digestibility in the ducks. Conclusion: These findings show that supplementation of feed with fresh alfalfa could have a significant effect on hybrid ducks in terms of growth performance, small intestinal histomorphology, and digestibility.

Effects of Saccharomyces cerevisiae Culture on Ruminal Fermentation, Blood Metabolism, and Performance of High-Yield Dairy Cows

High-yield dairy cows with high-concentrate diets are more prone to experiencing health problems associated with rumen microbial imbalance. This study assessed the effects of Saccharomyces cerevisiae culture (SC), a food supplement, on ruminal pH, volatile fatty acid (VFA), inflammatory cytokines, and performance of high-yield dairy cows. Forty Holstein cows with similar characteristics (e.g., milk yield, days of milk, and parity) were randomly divided into two groups: an experimental group fed the basal ration supplemented with the SC of 100 g of SC per cow per day (hour, SC group), and a control group fed the same basal ration diet without SC (i.e., CON group). On average, the supplementation of SC started at 73 days of lactation. The experimental period lasted approximately 70 days (from 18 January to 27 March 2020), including 10 days for dietary adaptation. Milk yield was recorded daily. Rumen fluid and milk samples were collected after 2 h of feeding in the morning of day 0, 15, 30, and 60. The data showed that rumen pH increased (p < 0.05) when cows were provided with SC. On average, the cows in the SC group produced 1.36 kg (p < 0.05) more milk per day than those in the CON group. Milk fat content of cows in the SC group was also higher (4.11% vs. 3.96%) (p < 0.05). Compared with the CON group, the concentration of acetic acid in the rumen fluid of dairy cows in the SC group was significantly higher (p < 0.05). There were no differences (p > 0.05) found in milk protein content and propionic acid between groups. The SC group had a tendency increase in butyric acid (p = 0.062) and total VFA (p = 0.058). The result showed that SC supplementation also enhanced the ratio between acetic and propionic. Most of the mean inflammatory cytokine (IL-2, IL-6, γ-IFN, and TNF-α) concentrations (p < 0.05) of the SC group were lower than CON group. This study demonstrated that high-yield cows receiving supplemental SC could produce more milk with higher fat content, have higher rumen acetate, and potentially less inflammatory cytokines.

Effect of Blend Oils from Waste Paring Coconut and Candlenut and Selenium for Formulating of Feed-in Nile Tilapia and Production Parameters

This study aims to get growth and feed efficiency of Nile tilapia (Oreochromis niloticus) with plant oils supplement from paring coconut (P.C.) and candlenut (C.N.) enrichment of Se in rations formula. The oil of P.C. was dominated by saturated fatty acid (SFA) lauric (42.67%), while the extract of C.N. was unsaturated fatty acids (UFA), linoleic (34.4%), and oleic (48.99%). The extract of P.C. and C.N. or mix oils added 4% in basal ration formula (28% crude protein (C.P.) with energy-protein ratio 8 kcal/kg). Completely Randomized Design (6 &times; 3) consists R1: basal ration; R2: basal formula with blend of paring coconut and candlenut oils (2% PC + 2% CN); R3: blend oils (R2) with trace additive Se; R4: 4% PC + Se; R5: 4% CN + Se; R6: control ration (32% CP). The result of production parameters showed that blend oils supplement enrichment Se 0.15 ppm in feed formula with ratio SFA: UFA = 1: 1 was the best growth rate equal with high protein feed. Feed efficiency ranged from 50.14-57.93% and protein efficiency ratio 1.72-2.06 both for CN oil (SFA: UFA = 1 : 2), paring coconut (SFA : UFA = 2 : 1) or blend oils (SFA : UFA = 1 : 1). Incorporation of blend oils with Se can be used for Nile tilapia fingerlings (&ge; 10 g). Paring coconut oil was trend increasing on feed efficiency for tilapia bigger stadium (&ge; 30 g).
