This study explored the impact of fresh sweet potato vine on the growth as well as the metabolites and colon microbial composition in Chinese Meishan gilt. Twenty Meishan gilts (body weight 30 ± 0.18 kg, n = 10 per treatment) were randomly assigned to a control (CON) or sweet potato vine (SPV) supplementation diet treatment. Gilts were housed in individual stalls. In the SPV treatment, 2 kg fresh sweet potato vine was used instead of 0.18 kg basal diet which provided the same amount of digestive energy and crude protein with the exception of crude fiber (CON, 51.00 g/d vs. SPV, 73.94 g/d) in terms of dry matter intake. Gilts were slaughtered and samples were collected on day 19 after the third estrus cycle. The SPV treatment tended to increase slaughter weight of gilts (p = 0.07); it also increased (p < 0.05) gastrointestinal tract weight and intestinal muscle layer thickness. SPV treatment also decreased (p < 0.05) carcass yield and subcutaneous adipose tissue. The concentration of zonulin and endotoxin in plasma was decreased (p < 0.05) as the gilt consumed the SPV diet. Colonic fecal concentrations of endotoxin, lipocalin-2, and tumor necrosis factor-α (TNF-α) were decreased (p < 0.05), and interleukin-10 (IL-10) was increased (p < 0.05) in the SPV treatment. Butyric acid and acetate concentration in colonic content as well as acetate concentration in caecal content were increased (p < 0.05) in the SPV treatment. Furthermore, the expression of carnitine palmityl transferase (CPT-1) and peroxisome proliferator-activated receptor-α (PPAR-α) in gilt liver in SPV treatment was increased (p < 0.05) in comparison with CON treatment. Meanwhile, the composition of the colon microbes was also altered by SPV; representative changes included an increase in Lactobacillus, Bacteroides, Roseburia, and Lachnospira. These results indicate that gilt fed with sweet potato vine had decreased gut permeability, endotoxin and pro-inflammatory cytokines concentrations; colonic fecal microbiota was also changed, which may be further beneficial to the intestinal health of Chinese Meishan gilt.

The study was carried out to determine the feed value of replacing maize with graded levels of sweet potato vine – cassava composite meal (SPV-CCM) to rabbits. Five treatment diets were formulated to contain SPV-CCM inclusion levels of 0% (control), 25%, 50%, 75% and 100%. Thirty weaned rabbits of mixed breeds and sexes were used for the experiment. They were randomly allocated to five dietary treatments with one rabbit as a replicate in a completely randomized design. Feed and water were provided ad libitum. Parameters measured were that of growth, digestibility, carcass and economics of production. The result showed that there was no significant (P>0.05) difference effect on final weight, total weight gain, daily weight gain and feed conversion ratio across the dietary treatments. There was no significant (P>0.05) difference on crude protein digestibility, crude fibre and ether extract which were within the required values for rabbit. There was no significant (P>0.05) difference on live weight at slaughter, dressing percentage, heart, liver, kidney, lungs/trachea, esophagus, stomach, small intestine, caecum, large intestine and visceral fat, there was however, a significant (P<0.05) difference in dressed weight, pancreases, spleen and kidney fat. A high cost of feeding, cost per kilogram diet and production was recorded in T and low cost of feeding, cost per kilogram diet and production in T . The result showed that 1 5 maize could be replaced by SPV-CCM up to 100% without any adverse effect on their performance, nutrient digestibility and carcass characteristics. However, the optimum performance was observed when 75% SPV-CCM replaced maize in the diet. Replacement of maize with SPV-CCM has relative cost advantage over the control diet and so should be incorporated in the diet of rabbit up to the level considered in this study.

Abstract ABSTRACT Background: A study was carried out in Loma district of Southern part of Ethiopia that aimed to determine the effects of supplementation of graded levels of sweet potato vine silage on growth performances of grazing indigenous goat breeds. Loma district, the potential area for sweet potato production, that they practiced feeding sweet potato for animal feed shortage especially during dry season in the study area. Two hundred Sixteen indigenous yearling male local goats (16.3±0.4kg) were randomly selected for on-farm feeding trial. The goats were blocked into four groups of fifty four animals based on their initial body weight. Dietary treatments were randomly assigned to each animal in the groups. Animals which were assigned randomly in each block were given to farmers. The treatment comprised of grazing alone as treatment 1, grazing+78 g dry matter sweet potato silage as treatment 2, grazing +156 g dry matter sweet potato silage as treatment 3, grazing + 234 g dry matter sweet potato silage as treatment 4. Results: The highest dry matter contents (89.7%) were observed in final trial periods compared to initial and mid-term of trial periods. The average daily gain for Treatment 4 was higher (P<0.05) than those goats in Treatment 1 and Treatment 2. The weight gain for Treatment 3 and Treatment 4 were similar (P>0.05). About 96.7% of the respondents produce sweet potato. Conclusions: In the current feeding trial study results indicated that, the increased supplementation of sweet potato vine silage revealed increased performance of grazing local goats. Intake of dry matter increased from 78% to 234% with increasing levels of sweet potato vine silage supplementation. There was higher average daily gain for the supplemented group (60, 80 and 97g/head/day in Treatment 2, Treatment 3 and Treatment 4, respectively) than non-supplemented ones (34.2g/head/day). Therefore, from these findings it is concluded that supplementation of sweet potato silage favors better growth rate however we need to work on improving the productivity of sweet potato and improve benefits of feeding to goats.
