“…Chu et al (2013b) reported that dietary of bamboo charcoal increased the average daily gain and feed efficiency in fattening pigs due to increased villus size (Lauronen et al, 1998). Moreover, the lower nutritional value of the experimental diet decreased carcass weight and backfat thickness .…”

“…Moreover, it was reported that bamboo charcoal was able to improve swine production by enhancing the feeding environment of fattening pigs and this material can be regarded as a secure feed additive and an alternative to antibiotics in animal production. Chu et al (2013b) reported that dietary of bamboo charcoal increased growth performance, feed efficiency and immunoglobulin concentration of plasma in fattening pigs. This expected that dietary of bamboo charcoal would improve swine production due to its ability to improve gastrointestinal environment.…”

The purpose of this study was to investage the effects of dietary bamboo charcoal on the carcass characteristics and meat quality of fattening pigs. Fifty four crossed pigs of 61.0±1.0 kg body weight (BW) were grouped and housed in 6 animals (3 barrows and 3 gilts) per pen and 3 replications per treatment. The basal diet (C) was supplied with 0.3% bamboo charcoal as treatment 1 (T1) and 0.6 % as treatment 2 (T2). The pigs were fed that experimental diet for 42 days, thereafter 10 longissimus dorsi (LD) per treatment were randomly collected at the time the pigs reached an average weight of 110.0±5.0 kg. The carcass weight, backfat thickness, and the carcass grade were better (p<0.05) in the pigs fed bamboo charcoal than in C. The crude fat concentration of LD was higher (p<0.05) in T1 than in C. While the composition of stearic acid and arachidonic acid was lower (p<0.05) in treatments than in C, the composition of oleic acid and linoleic acid of treatments was higher (p<0.05) than C. The physico-chemical characteristics, such as meat color and amino acid composition of LD were not affected (p>0.05) by the supplemented bamboo charcoal. In conclusion, dietary supplementation with bamboo charcoal improved the carcass grade and fatty acids composition of pork meat from fattening pigs, where the composition of unsaturated fatty acids was increased, but that of saturated fatty acids was decreased.

“…Similarly debated is the effect of ‘activated carbon’ or ‘activated charcoal (AC)’ on animal performance. Feeding charcoal was reported to increase feed intake, body weight and feed utilization in chicken (Kutlu et al., ) and pigs (Chu et al., ). Similarly, Van et al.…”

Irrigation agriculture of hot climates suffers from rapid soil organic carbon (C) turnover, high nitrogen (N) leaching and gaseous losses. In this context, we explored the possibility of supplementing ruminants with activated charcoal (AC) and condensed tannins (CT) to increase faecal concentration of long-lived C and slowly decomposable N. For this purpose, we fed AC and quebracho tannin extract (QTE, source of CT) to goats and determined nutrient digestibility, digesta passage and composition of faeces. The feeding trial comprised three periods, with 24 male goats assigned to five treatments and a control. On dry matter (DM) basis, the basal diet (control) consisted of 50% hay, 46.5% crushed maize and 3.5% soya bean meal. Treatment diets contained (on DM basis) 2% and 4% QTE (QTE2, QTE4), 1.5% and 3.0% AC (AC1.5, AC3.0) and a mixture of 2% QTE plus 1.5% AC (QTEAC). Samples of feed, refusals and faeces were analysed for chemical constituents; digesta passage was computed with a one-compartment Gamma-2 model from pulse-dose application of ytterbium-mordanted fibre and quantitative collection of faeces during 7 days. Compared to the control, organic matter and N digestibility were reduced with QTE2 and QTE4 (p ≤ 0.001), that of neutral and acid detergent fibre (NDFom, ADFom) decreased with QTE4, QTEAC and both AC treatments (p ≤ 0.001). Ruminal particle passage ranged from 0.051 h (QTEAC) to 0.056 h (control; p > 0.05). Apart from the correlation between total tract mean retention time and faecal C/N ratio (r = -0.35), passage parameters did not affect faeces quality. While faecal N concentration was not altered by both additives, AC enhanced faecal NDFom, ADFom and C concentrations (p ≤ 0.001). Whereas feeding up to 3% AC might slow down the decomposition of manure in the field without negatively affecting the digestive physiology of goats, including QTE seems not advantageous from a physiological and nutrient recycling perspective.

“…Recently increased focus on environment pollution has led to the requirement of reducing nitrogen excretion by farm animals (Chu et al 2013;Yan & Kim 2013). It has been well accepted that the use of crystalline amino acids (AA) in low crude protein (CP) diets can reduce the nitrogen excretion in swine manure by more than 35% (Le et al 2006;Nyachoti et al 2006).…”

Two experiments were conducted to evaluate the effects of different levels of threonine:lysine (Thr:Lys) ratios on growth performance, blood urea nitrogen (BUN) concentration, and nitrogen balance in weaned pigs. In Experiment 1, a total of 90 weaned pigs (Landrace × Yorkshire × Duroc) with an initial average body weight (BW) of 6.57 ± 0.46 kg were allocated into three treatments for 35 days. Each treatment had six replicate pens with five pigs per pen. Diets were formulated with different apparent ileal digestible (AID) Thr:Lys ratios of 0.62, 0.67, and 0.72. Dietary AID of Lys and Thr concentrations were set at 10.8 and 6.7, 7.2, 7.8 g/kg, respectively. Throughout the experiment, average daily gain, average daily feed intake, and feed:gain ratio were not influenced (P > 0.05) by dietary Thr:Lys ratios. However, BUN concentration was increased (linear, P = 0.01) as the Thr:Lys ratio increased at day 35. In Experiment 2, a total of 24 weaned pigs with an average BW of 8.57 ± 0.32 kg were individually housed in metabolic cages and fed for 10 days. Dietary treatments were the same as in Experiment 1. Nitrogen intake, nitrogen excretion in feces and urine, and nitrogen retention were not influenced (P > 0.05) by dietary Thr:Lys ratios. In conclusion, increasing dietary AID Thr: Lys ratio (0.62, 0.67 vs. 0.72) could not improve the growth performance and nitrogen balance in weaned pigs.
