This research was conducted to study the effect of fertilizer types and photoperiod on the nutrient content of regrowth I on alfalfa (Medicago sativa L.). The variables measured were nutrient content i.e dry matter (DM), organic matter (OM), crude protein (CP), and crude fat (CF). The research applied statistical analysis Completely Randomized Design (CRD) factorial pattern 5x3 and t-test. If it resulted in a significant effect, it was continued with Duncan’s multiple range test (DMRT). The first factor was types of fertilizer consisted of P0=control, P1=green fertilizer and dolomite, P2=manure, green fertilizer and dolomite, P3=dolomite, and P4=green fertilizer® and dolomite. The second factor was the photoperiod consisted of C0=12 h, C1=16 h, and C3=20 h. The results showed that the fertilizer types treatments were significantly affected (P<0,05) regrowth I DM, and regrowth I CF. While photoperiod treatment were significantly affected (P<0,05) regrowth I DM, regrowth I OM, and regrowth I CF. The interaction between the types of fertilizer and photoperiod treatment was significantly affected (P<0,05) regrowth I DM and CF. Based on research results, it can be concluded that the types of green fertilizer from PIAT and dolomite to produce the nutrient content regrowth I was the highest, resulting in 22,18% DM, 29,32% CP, 9,38% CF respectively. The nutrient content of regrowth I that produce the highest results of photoperiod was 12 h = 28,80% CP, 16 h = 20,92% DM, 20 h = 89,38% OM, 9,16% CF.
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.
This study aimed to determine the effect of alfalfa fresh or hay supplementation in the diets on the meat quality of hybrid duck. 75 hybrid ducks with 3 treatments and 5 replications were used in this study. Each replication consisted of 5 ducks. The diets were used in the trial consisted of P0 = Basal diets without alfalfa supplementation, P1 = Basal diets + 6% fresh alfalfa supplementation and P2 = Basal diets + 6% alfalfa hay supplementation. Either fresh or hay alfalfa was computed based on dry matter. Drinking water was given in ad libitum. Parameters observed were live weight, carcass weight, carcass percentage, and income. This study was designed with Completely Randomized Design. Data collected were analyzed (Anova) with Statistical Product for Service Solution version 22. Duncan’s new Multiple Range Test was used in the analysis with significant results. Supplementation of 6% fresh and hay alfalfa did not increase live weight, carcass weight and carcass percentage of hybrid duck until the age of 35 days. However, supplementation of alfalfa (fresh or hay) can reduce the feed cost, thus giving impact to income. The highest income was earned from the duck with 6% alfalfa hay supplementation followed by 6% alfalfa fresh and control. It is recommended to sell the live weight of 35 days harvested duck instead of the carcass to raise the income.
