“…These by-products are good energy sources for livestock, and with proper preservation procedures, they could be beneficial to the livestock farming community and ease the burden of food competition between humans and animals (Lan et al, 2021). In Cambodia, Chinese taro variety petioles are harvested, cooked, and consumed by locals, while wild taro variety petioles are used as pig feeds after cooking, but never used for human consumption because they are poisonous and allergic (Buntha et al, 2008b).…”

Background. Taro (Colocasia esculenta) is one of the underutilized crops in Kenya, grown under a wide range of environmental and edaphic conditions. This crop has exceptional dietary value and numerous culinary applications due to its edible leaves and corms. However, the mineral nutrient composition of taro in Kenya is still not well known due to a lack of scientific information concerning production. Objective. To determine the proximate composition and mineral profile of taro under different watering regimes and planting densities in Embu, Kenya. Methodology. A study was conducted at the Kenya Agricultural and Livestock Research Organization (KALRO) – Embu Research Centre, during the long rains (LR) 2021, and short rains (SR) 2021/2022. A factorial experiment with a split-plot layout arranged in a completely randomized block design was adopted. The watering regimes (100 %, 60 %, and 30 % based on the field capacity (FC)) were the main factor while the sub-factor was the planting density, with three replications. The planting densities used were 0.5 m × 0.5 m (40,000 plants ha-1), 1 m × 0.5 m (20,000 plants ha-1), and 1 m × 1 m (10,000 plants ha-1), representative of high, medium, and low planting densities respectively. Proximate analysis and mineral content were determined. Results. Significant differences (P < 0.05) in seasons were noted for protein, fibre, potassium, calcium, sodium, and zinc in the taro corms. The high carbohydrate content observed in this study (35 – 39 %) indicates that taro tubers are a good source of nutritional energy. Potassium (> 5000 mg kg -1) and magnesium (> 1000 mg kg -1) were the most prevalent mineral elements in taro corms and leaves, with copper (< 25 mg kg -1) being the least prevalent. Implications. Consumption of nutrient-rich foods such as taro helps the body to utilize the necessary nutrients to combat malnutrition and promote food security in rural communities. Conclusion. Taro leaves can be recommended as leafy vegetables as they are good sources of potassium, magnesium, calcium, manganese, iron, copper, and zinc; and the corms have low fat and protein content, high calorific energy, and high carbohydrate content. Taro represents one of the main sources of energy in many parts of the tropics and its production can be recommended in sub-humid areas in Kenya.

“…In traditional diets, maize represents between 50% and 70% of the diet content, which considerably increases the costs of production [31]. The use of cassava and taro as a food alternative due to their high digestibility [32][33][34] provides acceptable results for production [12,22,35,36]. However, due to the content of antinutritional factors in both feed alternatives, it is necessary to subject them to prior cooking to reduce their negative effects [37][38][39][40].…”

Ecuadorian small producers use crossbred animals with a low level of genetic improvement, which are fed with alternative feeds to decrease production costs. The objective of this study was to evaluate the effects of geographical location and three diets according to the amount of cassava and taro incorporated into the feed (T1 conventional feed; T2 and T3 with 32% and 42% of cassava and taro, respectively) in pigs reared under the backyard system. The results did not show many differences between the treatments for morphological traits; however, between geographical locations, significant differences were evidenced. The fat content from the first rib was higher in the T1 group. The intramuscular fat percentage was higher in the T1 group, contrary to the protein levels, which were higher in the T3 group in Esmeraldas and the T2 group in Ro Chico. In the gastrointestinal tract (GIT) and its attached organs, differences were found in the empty stomach weight, full and empty small intestine weight, liver weight, and total GIT weight, with the T2 and T3 groups having the largest and heaviest. Cassava and taro did not affect the morphometric behavior and quality of the carcass but increased the amount of protein in the meat and the weight of the GIT. Geographical location was also observed to have a significant effect.

The experiment was carried out at the station of Agricultural Research of Svay Rieng University, and was carried out from 15th April to 17th June 2023 with the title “Utilization of ensiled cassava leaf and taro mixed with waste of soybean meal as protein sources fed different sources of energy on fattening crossbred pigs”. This research has 3 objectives: 1. To compare DM feed intake of crossbred pigs, 2. To compare the growth rate of crossbred pigs, and 3. To compare the feed conversion of crossbred pigs. There were 12 pigs were arranged within 2*2 factorial design through Randomized Complete Block Design (RCBD) with 3 replications. The factor with the energy source: rice bran or broken rice and the factor with the protein source: Ensiled taro mixed with waste of soybean meal or Ensiled cassava leaf mixed with waste of soybean meal. The treatments of the study are: T1: Ensiled Taro 30% + Waste of Soybean Meal 20% + Rice Bran 49% + Premix 1%; T2: Ensiled Taro 30% + Waste of Soybean Meal 20% + Broken Rice 49% + Premix 1%; T3: Ensiled Cassava Leaf 25% + Waste of Soybean Meal 25% + Rice Bran 49% + Premix 1%; and T4: Ensiled Cassava Leaf 25% + Waste of Soybean Meal 25% + Broken Rice 49% + Premix 1%. The period of experiment were 60 days only. All data were collected daily such as feed offer and feed refusals. Those pigs were weighed at every 10 days from the starting of the experiment until the end of experiment. The experiments’ results were found that total intake on the energy sources were higher significant differently in broken rice compared with the rice bran (P<0.01) as total intake on the protein sources were higher significant differently on the ensiled taro mixed with waste of soybean meal (P<0.01). Growth rate on the energy sources were higher significant differently in broken rice as compared to the rice bran (P<0.01) while growth rate for the ensiled taro plus waste of soybean meal was slightly high if compared with the ensile cassava plus waste of soybean meal (P>0.05). Feed conversion ratio on the energy sources was better significant in broken rice compared to the rice bran (P<0.01) while feed conversion for ensiled taro mixed with waste of soybean meal was slightly better as compared with the ensile cassava plus waste of soybean meal (P>0.05). In conclusion, the use of the protein source from the ensiled taro mixed with waste of soybean meal plus the energy source of broken rice or rice bran, the pigs were increased on total intake, live weight gain and good improvement of feed conversion rather than the use of ensiled cassava leaf mixed with waste of soybean meal plus broken rice or rice bran. The research outcome indicated that efficiency of protein offering is asked to use the ensiled taro with waste of soybean meal combination with basal diet of broken rice or rice bran on reproduction of sows in the next trial.
