EFFECT OF PARTLY SUBSTITUTION OF BASAL DIET WITH SWEET POTATO VINES (Ipomoea batatas)  MEAL ON ENERGY AND PROTEIN DIGESTIBILITY OF PIGS. Pork is one of the meat producer animals that can contribute to satisfy animal protein requirements. Sweet potato vines is considered as an agricultural waste product and can be used as feedstuff for pigs. The present  study was conducted to determine the utilization of sweet potato vines  substituting basal diet on energy and protein digestibility of finisher pigs. Five ‘Duroc X Spotted Poland China’ castrated male pigs, aged 3.5 to 4.0 months with an initial body weight 50 kg (±2.5 kg) were assigned to four treatments as follow: R0 = 100% basal diet + 0% sweet potato vines meal; R1 = 92.5% basal diet + 7.5% sweet potato vines meal; R2 = 85% basal diet + 15% sweet potato vines meal; R3 = 77.5% basal diet + 22.5% sweet potato vines meal; and R4 = 70% basal diet + 30% sweet potato vines meal. Parameters measured were: energy and protein digestibility. Research reasults showed that there is no significant differences  (P > 0.05) among treatments on energy and protein digestibility of pigs in the present study. This indicated that utilization of sweet potato vines meal up to 30% replacing basal diet did not affect digestible energy and protein of finishing pigs. It can be concluded that substituting basal diet with sweet potato vines meal up to 30% has no negative effect on energy and protein digestibility of finishing pigs.   Keywords: Sweet potato vines, energy digestibility, protein digestibility, pigs

Abstract Sweet potato is an important ‘indigenised’ root crop in South Africa. It features prominently in smallholder cropping systems because of its versatility, drought tolerance and positive role in food security. It outranks most staple crops in vitamins, minerals, dietary fibre and protein content. Much information is available on sweet potato as a drought tolerant and food security crop, but critical reviews that link its drought tolerance with food security are lacking. We review sweet potato as a food security crop, focusing on mechanisms associated with drought. We conclude that the crop has great potential in the light of imminent challenges associated with drought as a negative effect of climate change.

AbstractThe effects of feeding dried sweet potato (Ipomoea batatas) leaf (SPL) on growth performance, digestibility, and nitrogen (N) utilization were studied in sheep. Twenty-four rams with initial body weight of 18.5 ± 1.49 kg were randomly allocated to four treatments containing ad libitum natural grass hay alone (T1), hay + 150 g SPL (T2), hay + 300 g SPL (T3) and hay + 450 g SPL (T4) on as fed basis. Results indicated that dry matter (DM), organic matter (OM) and crude protein (CP) in-takes increased (P < 0.001) with increasing levels of SPL. Sheep fed with T2, T3 and T4 diets gained 55.1, 52.6 and 66.5 g per head per day, respectively, while the gain of non-supplemented sheep (9.19 g per head per day) differed (P < 0.05). Digestibility of DM, OM, and CP was higher (P < 0.01) for all supplemented sheep compared with the control. The CP digestibility and N retention were negative in non-supplemented sheep. Urinary N excretion decreased (P < 0.001) with the increasing levels of SPL supplementation. The N retention improved with the increasing levels of SPL and was the highest (P < 0.001) in sheep fed with T4 diet and the lowest in non-supplemented sheep. In conclusion, supplementing a basal diet of natural grass hay with SPL considerably improved the average daily gain, OM and CP digestibility and N retention.

Sweet potato leaf (Ipomoea Batatas) is a potential agricultural waste is used as animal feed to Goat crossbreed of Ettawa. Sweet potato leaf (Ipomoea Batatas) has a high enough protein content (> 20%), so it can be used as a source of protein goat crossbreed of Ettawa. This research aims to determine the effect of feeding of sweet potato leaves (Ipomoea Batatas) as feed on goat body weight of goat crossbreed of Ettawa. This research has been conducted in February to March 2015, located in Wonua Raya village, Toari district, Kolaka Regency. This research uses 12 goats crossbreed of Ettawa which is divided into 12 plots of cages. In this research, four levels of feeding treatment were applied: regular feed/Gamal leaf (R0), 90% Gamal leaves + 10% sweet potato leaves (R1), 85% Gamal leaves + 15% sweet potato leaves (R2), 80 % Leaf Gamal + 20% sweet potato leaves (R3). The results showed that the use of sweet potato leaves on weighing 15 days did not significantly affect the rate of body weight and had a significant effect on considering at day 30 (p

Heat treatment can affect the bioactive compounds in sweet potato (SP). In this work, we monitored the influence of heat treatment (boiling, steaming, microwaving, and baking) on the total polyphenols content (TPC), total antioxidant capacity (TAC), total anthocyanins content (TANTC), and phenolics acids (chlorogenic (CGA), neochlorogenic (neo-CGA), and trans-ferulic (tFA)) in two SP varieties grown in Slovakia and Croatia. TPC, TAC, and TANT were determined spectrophotometrically and phenolic acids by HPLC. TPC ranged from 576 (Beauregard, Croatia; Be/HR) to 3828 (414-purple, Slovakia; Pu/SK) mg/kg DW in the raw SP tubers. After heat treatment, TPC increased, most in steamed SP (8438 mg GAE/kg DW; Pu/SK), while only in boiled SP (Be/HR), TPC decreased (353 mg GAE/kg DW). TAC varied from 0.848 (Be/HR) to 8.67 (Pu/HR) (μmol TE/g DW) in raw SP. The TAC increased by heat treatment (max. 14.2 μmol TE/g DW; cooking Be/SK), except for Pu/HR. The TANT ranged from 151 (raw Pu/SK) to 1276 (microwaved Pu/SK) mg CyE/kg FW. Heat treatment had a negative effect on phenolic acid content; the largest reduction was after boiling: CGA by 29% (Pu/SK), neo-CGA by 69% (Pu/HR), and tFA by 29% (Be/HR). The influence of heat treatment on the monitored quantities is not definite.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan.

<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>
