“…Feed additives such as enzymes, essential oils, and benzoic acid and their combination can improve growth performance in broiler chickens (Giannenas et al, 2014). Mohana Devi et al (2014b) reported that supplementation of protein sources in growing pig diets improved the growth rate and feed intake. Dietary supplementation with medium-chain fatty acids together with probiotic in weaning pigs can improve growth performance, increase nutrient digestibility, and enhance biochemical profiles (Mohana Devi and Kim, 2014).…”

-The objective of the present study was to evaluate the effects of blends of dietary protected organic acid supplementation on growth performance, nutrient digestibility, blood profiles, faecal microflora, and gas emission on sows and piglets with emphasis on their modes of action to improve pig performance. A total of 12 sows with an average initial body weight (BW) of 252.40±11.7 kg were used in this trial. Growth performance, blood profiles, and nutrient digestibility of sows and piglets fed protected organic acid were evaluated. The dietary treatments included a basal diet (CON); CON + 0.1% protected organic acid; and CON + 0.2% protected organic acid. The BW and back fat of sows was checked four days prior to farrowing and at the weaning day to calculate BW loss and back fat loss during that period. Inclusion of 0.2% protected organic acid provided a greater digestibility than CON diets throughout the experimental period in lactating sows. Dietary supplementation with 0.2% protected organic acid led to a higher white blood cell and lymphocyte concentration than CON treatment in sucking piglets. Immunoglobulin G concentration observed was greater in protected organic acid groups in lactating sow and sucking piglets. Increased faecal Lactobacillus counts with decreased E. coli concentrations were observed with the diets of protected organic acid fed to lactating sows. The E. coli counts were decreased in weaning piglets. The faecal H 2 S contents were decreased in 0.2% protected organic acid diets during farrowing on day 1. Dietary supplementation with protected organic acid blends beneficially affects the nutrient digestibility, ileal noxious gas (NH 3 and H 2 S) emission, as well as intestinal microbial balance in lactating sows.

“…Blood urea N concentration was analyzed using the Abbott Spectrum Urea N test (Series II; Abbott Laboratories, Dallas, TX), and blood creatinine concentration was determined using an Astra-8 Analyzer (Beckman Instruments, Inc., Brea, CA;Mohana Devi et al, 2014). Cross-sections of intestinal samples from formalin-preserved segments were prepared using standard paraffin embedding techniques and were cut approximately 6 μm thick with a microtome and stained with azur A and eosin.…”

This experiment was conducted to investigate the effect of a spp.-based direct-fed microbial (DFM) on growth performance, apparent total tract digestibility (ATTD), blood profile, intestinal histomorphology, and fecal gas emission in piglets fed corn and soybean meal-based diets. The DFM product was based on 1 strain of and 2 strains of and formulated to supply 1.5 × 10 cfu/g of feed. A total of 128 piglets ([Yorkshire × Landrace] × Duroc; 6.8 ± 0.6 kg BW; weaning age: 24 d) were housed in groups (4 pigs/pen, 2 barrows and 2 gilts) and fed diets ( = 16) without or with DFM in a 2-phase feeding program: d 0 to 14 (phase I) and 15 to 42 (phase II). Feed intake and BW were measured weekly. At the end of each phase, samples for blood urea nitrogen (BUN), blood creatinine, ATTD, and fecal noxious gas emission were taken. At termination, 12 piglets per treatment were killed to access intestinal tissues for histomorphology. Overall, pigs fed DFM had a greater ( < 0.05) G:F than pigs fed the control diet. In phase I, pigs fed DFM showed a greater ( < 0.05) ADG and lower ( < 0.05) concentration of BUN and fecal ammonia emission than the control group. In phase II, a greater ( < 0.05) ATTD of nitrogen and longer ( < 0.05) duodenum and jejunum villi were observed in pigs fed the DFM diet compared with the control group. In conclusion, inclusion of DFM improved growth performance and villi length of the duodenum and jejunum in nursery pigs. Furthermore, DFM enhanced protein utilization as demonstrated by increased nitrogen digestibility, lower BUN, and lower fecal ammonia release.

This work aimed to determine the effects of dietary full-fat or defatted black soldier fly larvae (BSFL) to replace protein sources on growth performance, blood parameters, intestinal morphology, and intestinal microbiota in nursery pigs and to investigate the effects of dietary defatted BSFL at up to 30% at the expense of protein sources on growth performance in nursery pigs. In Exp. 1, a total of 36 barrows with an initial body weight of 7.0 kg (standard deviation = 0.8) were allotted to 3 dietary treatments in a randomized complete block design with 4 replicate pens per treatment and 3 barrows per pen. A corn-soybean meal (SBM)-whey-based control diet was prepared with soy protein concentrate and fish meal as additional protein supplements. Two additional diets were prepared to include 20% full-fat BSFL or 20% defatted BSFL to replace soy protein concentrate and fish meal to maintain the same energy and nutrient concentrations in all diets. In the 28-day feeding trial, pigs fed the diet containing defatted BSFL tended to consume more feeds (P < 0.10) than other groups during days 14 to 28 and the overall period. On day 28, the serum blood urea nitrogen in pigs fed the control diet was less (P < 0.05) than that fed the full-fat or defatted BSFL, but fecal score and jejunal morphology did not differ among the treatment groups. Relative abundance of Mycoplasma in the ileal digesta was less (P < 0.05) in the pigs fed the diet containing full-fat or defatted BSFL compared with the control group. In Exp. 2, a total of 192 pigs with an initial body weight of 7.8 (standard deviation = 1.2 kg) were randomly allotted to one of 4 dietary treatments in a randomized complete block design with 6 replicate pens per treatment and 4 barrows and 4 gilts per pen. A control diet was mainly based on corn, SBM, fermented SBM, fish meal, and spray-dried plasma protein. Three additional diets were prepared to contain 10%, 20%, and 30% defatted BSFL to replace SBM, fermented SBM, fish meal, and spray-dried plasma protein to maintain for the same energy and nutrient concentrations. Average daily gain, average daily feed intake, gain:feed, and fecal score were not affected by increasing dietary defatted BSFL. Overall, dietary black soldier fly larvae did not compromise growth performance or intestinal health in nursery pigs. Black soldier fly larvae can be used in nursery pig diets to replace other protein sources without negative effects.
