“…Compared to N, P efficiency for fattening pig is higher, whereas K efficiency is much lower, as well as heavy metal efficiency. These results are consistent with literature results (Jongbloed, 1991;Levasseur, 1998;Ferket et al, 2002).…”

A mathematical model was developed from literature data to predict the volume and composition of pig's excreta (dry and organic matter, C, N, P, K, Cu and Zn contents), and the emission of greenhouse gases (CH 4 and CO 2 ) though respiration and from the intestinal tract, for each physiological stage (post-weaning and fattening pigs and lactating and gestating sows). The main sources of variation considered in the model are related to animal performances (feed efficiency, prolificacy, body weight gain, etc.), to water and nutrient intakes and to housing conditions (ambient temperature). Model predictions were validated by using 19 experimental studies, most of them performed in conditions close to those of commercial farms. Validation results showed that the model is precise and robust when predicting slurry volume ( R 2 5 0.96), slurry N ( R 2 5 0.91), P ( R 2 5 0.95) and to a lesser extent dry matter ( R 2 5 0.75) contents. Faeces and urine composition (minerals and macronutrients) can also be precisely assessed, provided the composition and the digestibility of the feed are well known. Sensitivity analysis showed strong differences in CH 4 emission and excretion amounts and composition according to physiological status, animal performance, temperature and diet composition. The model is an efficient tool to calculate nutrient balances at the animal level in commercial conditions, and to simulate the effect of production alternatives, such as feeding strategy or animal performance, on excreta production and composition. This is illustrated by simulations of three feeding strategies, which demonstrates important opportunities to limit environmental risks through diet manipulations.

“…High concentrations of NH 3 or H 2 S can cause hazardous effects to humans and animals (Drummond et al 1980;Zhang and Kim 2014). It has been suggested that excreta ammonia gas emission is related to nutrient utilisation and the intestinal microbial ecosystem (Ferket et al 2002). In our study, NH 3 gas emission was reduced by addition of Bacillus subtilis DSM 17299, Clostridium butyricum and Lactobacillus acidophilus to the diet.…”

ABSTRACT:This study was conducted to evaluate the effects of Bacillus subtilis, Clostridium butyricum and Lactobacillus acidophilus (tri-strain probiotics, TSP) endospores in broilers. TSP can benefit the host animal by increasing nutrient absorption from the gastrointestinal tract and altering the intestinal ecosystem in poultry. A total of 500 day-old ROSS 308 mixed sex broiler chickens with an average initial body weight (IBW) of 45 g ± 0.6 g were used in this 35-day feeding study. Broiler chickens were randomly allotted to one of five dietary treatments: (1) CON (antibiotic free diet), (2) ANT1 (CON + enramycin 5 ppm), (3) ANT2 (CON + avilamycin 5 ppm), (4) TSP1 (CON + 0.1% TSP), and (5) TSP2 (CON + 0.2% TSP) with five replicates per treatment and 20 chicks per pen. Broiler chickens fed on TSP diets exhibited linearly increasing body weight gain (BWG) and decreased feed conversion ratio (FCR) compared to those on the CON diet (P < 0.05; Day 21 to Day 35 and Day 1 to Day 35, respectively). Further, dry matter (DM) and nitrogen (N) digestibility were improved (P < 0.05) in the TSP treatment at the end of study. The inclusion of TSP reduced (linear, P = 0.02) meat lightness (L*) compared with CON and ANT treatments. Broiler chickens fed with TSP diets had relatively higher (linear, P < 0.05) bursa weight than those fed with ANT and CON diets. The supplementation of TSP increased (P < 0.05) the ileal and caecal Lactobacillus count compared with CON and ANT diets. The ileal and caecal Escherichia coli and caecal Clostridium perfringens counts were reduced (P < 0.05) in the TSP2 group compared with the CON group. Broiler chickens fed with TSP diets exhibited increased (P < 0.05) caecal Bifidobacteria counts compared with CON and ANT diets. Excreta ammonia (NH 3 ) gas emission was lower (P < 0.05) with the TSP treatment compared with the CON treatment. In conclusion, the supplementation of TSP improved growth performance, nutrient digestibility, meat quality, gut health and reduced noxious gas emission in broilers.Keywords: ammonia gas emission; body weight gain; bursa weight; Escherichia coli; Lactobacillus; meat lightness List of abbreviations BWG = body weight gain, FCR = feed conversion ratio, DM = dry matter, L* = meat lightness, N = nitrogen, NH 3 = ammonia, TSP = tri-strain probiotics

“…Wenk (2003) also observed that the inclusion of herbs or herbs extract could reduce the faecal noxious gas content in growing pigs by manipulating the microflora in the gastrointestinal tract of pigs. Ferket et al (2002) have previously suggested that the ultimately faecal noxious gas emission of animals is related to intestinal microflora and nutrient utilization. In this study, we found that AGE supplementation had reduced excreta E. coli count but no effect on excreta gas production compared to basal diet.…”

The design of this study was to investigate the impacts of dietary supplementation with aged garlic extract (AGE) by Leuconostoc mesenteroides KCCM35046 on egg production, egg quality, odour gas emissions from excreta, excreta microbiota, haematological characteristics and fatty acids composition of egg yolk in laying hens. A total of 384, 54-week (ISA-brown) laying hens were randomly assigned to one of four treatments with eight replications per treatment and 12 adjacent cages as a replication. The experimental treatments were: (1) CON; basal diet, (2) AGE.05; CON + .05% aged garlic extract, (3) AGE.1; CON + .1% aged garlic extract, (4) AGE.2; CON + .2% aged garlic extract. No significant differences were observed in feed intake (FI) and egg production among treatments (P > .05). Laying hens fed with the AGE linearly improved yolk height at Week 3 (P = .02). The inclusion of .1% AGE had increased Haughunit (HU) at Week 4 (quadratic, P = .01). At the end of the experiment, AGE diet linearly increased yolk height and egg shell thickness (P = .01 and .03, respectively). No significant differences were observed in excreta gas emission (P > .05). The supplementation of AGE linearly reduced excreta E. coli concentrations (P = .02). Inclusion of AGE led to a greater lymphocyte and IgG concentrations (linear, P = .04 and P = .03, respectively), whereas blood total cholesterol (TC) was reduced by the AGE supplementation (linear, P < .01). PUFA: SFA was increased in AGE treatment at the end of the experiment (P < .05). In conclusion, the administration of AGE at a level of .1 and/or .2% can improve egg quality, blood lymphocyte, IgG concentrations and reduced excreta E. coli and blood TC in the laying hens.ARTICLE HISTORY
