The use of probiotics (Lactobacillus  sp.) in feed is one alternative that is done to improve immunostimulants, growth stimulants, and can be used as a balance of microorganisms in digestion. This study aimed to evaluate the growth performance of vanamei shrimp fed with the addition of Lactobacillus  sp. with sweet potatoes in feed. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment was by feeding with different sweet potato concentrations: A) The dose of sweet potato in feed was 0% (as control); B) The dose of sweet potato in feed was 10%; C) 1The dose of sweet potato in feed was 15%; and D) The dose of sweet potato in feed was 20%. Data were analyzed using variance analysis (ANOVA) and continued with W-Tuckey's further test. The research parameters were digestive enzyme activity, nutrient digestibility, and growth. The results of the variance analysis showed the addition of various sweet potato concentrations with Lactobacillus sp. has no significant effect (p> 0.05) of the growth rate. The specific growth rate of vannamei shrimp ranges from 3.06 to 3.23% / day. Based on the results of the analysis on the utilization of sweet potatoes as a prebiotic on the performance of Lactobacillus sp. in the vannamei shrimps (Litopenaeus vannamei) digestive tract can be concluded that the growth performance does not have a significant effect after being fed with the addition of Lactobacillus sp. and sweet potatoes in feed.

Anatomical characters can be used as instructions to the structural resistance of plants to pathogen attack. Various pathogens attack sweet potato plants, such as the Sphaceloma batatas fungus that causes scurvy disease (scab). The aims of this research t test the structural resistance of sweet potato plants based on leaf anatomical character and intensity of disease attack due to the inoculated of S. batatas. The research was conducted from June to November 2016, using the Completely Randomized Design Experimental (RAL) method with a factorial pattern. The first factor was ten sweet potato cultivars and the second factor was the inoculum of S. batatas fungus each treatment with five replications. The character of leaf anatomy observed was thick of cuticle, thick of mesophyll, size and number of stomata and number of trichomes per 1 mm2 leaf area. Based on the research result, it was concluded that the inoculation of the fungus of S. batatas caused the decrease of stomata length and width on ten sweet potato cultivars. The highest intensity of disease attack was 14.33% and correlated with stomata length (r = 0.49). The anatomical structural resistance to scurvy can be used as a basis for determining crosses for obtaining superior sweet potato cultivars. The benefit of the research is to advise the community to cultivate sweet potatoes that have structural resistance to scurvy, such as cuticle and thick mesophyll, high trichomata density.

Synbiotic application shows better results compared to the single use of probiotics or prebiotics. SKT-b bacteria have been shown to act as probiotics for aquatic animals, as well as sweet potatoes that are known to act as prebiotics. This study aims to examine the synbiotic potential of SKT-b probiotic bacteria and oligosaccharide extract from sweet potato in improving the growth performance of vaname shrimp. Shrimp were treated with synbiotic feed with different prebiotic concentrations of 1% (Pro + Pre 1%), 2% (Pro + Pre 2%) and 3% (Pro + Pre 3%). The treated food was given to shrimp (weight ± 1.9 g) for 30 days. Oligosaccharides extracted from sweet potato can act as a prebiotic which increases the bacterial population in vaname shrimp’s intestine. The application of synbiotics can improve the growth performance of vaname shrimp including the addition of body weight, feed efficiency, digestive enzyme activity, protein retention and body fat of shrimp. The treatment of Pro + Pre 2% and Pro + Pre 3% shows better growth performance of vaname shrimp.

Abstract We previously found that i.m. injection of GRA, similar to in-feed antibiotics, improves measures of intestinal integrity, nutrient digestibility, and overall growth performance in nursery pigs. In addition, we have demonstrated that the mitigating effects of GRA on the stress of weaning is predominantly done by subsiding the inflammatory response that often accompanies early weaning. The objective of the current study was to explore the most practical methods for delivering GRA to newly weaned pigs. One-hundred and sixty-seven PIC pigs were weaned at 25 ±1.0 days of age (BW 7 ±1.2 kg), and assigned to fourteen treatments (3-4 pigs /pen; 3 pens/treatment). Seven treatments were tested within two sexes (gilts vs. barrows). The treatments were: 1) i.m. injection of GRA (two injections, 0.2 mg/kg BW at -1 and 3 d post-weaning), 2) two levels of in-water GRA (0.8 and 1.6 ppm), 3) in-feed GRA (2.5 and 5.0 ppm), 4) in-feed antibiotic (ANT, 100 ppm tylosin), and 5) control. Dexamethasone was used as GRA. Pigs had free access to in-feed or in-water GRA or ANT during the 1st-week post-weaning. Parameters of growth performance were measured weekly until the end of the nursery phase. A completely randomized design and repeated measurement ANOVA (PROC MIXED) in SAS were used for statistical analyses. In-water, in-feed, and i.m. GRA treatments resulted in growth performance outcomes comparable to that of in-feed ANT. Relative to CON pigs, both ANT and GRA improved ADG and G: F during the nursery phase (P &lt; 0.05). Among the delivery methods tested, 2.5 ppm of in-feed GRA resulted in superior ADG (GRA vs. CON; 0.29 vs. 0.20 kg/d) and G: F (0.63 vs. 0.40 ± 0.05), compared to the control group (P &lt; 0.02). Collectively, these results suggested that in-feed treatment is the best method for delivering GRA to newly weaned pigs.
