The aim of this study was to investigate the effect of dietary supplementation of nanoparticle trivalent chromium on chromium absorbability, growth performance, blood parameters and carcass characteristics of pigs. In Trial 1, five growing pigs (Landrace × Yorkshire × Duroc) (initial average weight was 31.3 ± 2.0 kg) were used in a 5 × 5 Latin square design as the Control group (without supplement of chromium), the chromium chloride group (CrCl3), the chromium picolinate group (CrPic), the nanoparticle chromium chloride group (NanoCrCl3), and the nanoparticle chromium picolinate group (NanoCrPic). The pigs were adapted for 7 days, followed by a 5-day test period and a collection period. The chromium was added at a 200 μg/kg level to the diet using different chromium sources for evaluating the chromium absorbability. The results of Trial 1 indicated that there were no differences in feed components digestibility among the groups, but the absorbability of chromium in the NanoCrPic (27.5%) group was the highest, whereas that in the CrCl3 group was the lowest (4.91%). Moreover, the chromium source, nanoparticle size and interaction effects were observed between these two factors (P < 0.001). In Trial 2, 60 Landrace × Yorkshire × Duroc growing pigs (average bodyweight was 76.7 ± 4.5 kg) were randomly allotted to five dietary treatment groups as used in Trial 1, each group with four pens (three pigs/pen). The study was conducted for 60 days. Their growth performance, carcass and meat traits were also evaluated. Trial 2 results indicated that feed intake in the chromium-added groups was greater (P < 0.007) than that in the Control group. The average daily bodyweight gain in the chromium-added groups was greater than that in the Control group (P = 0.046). The serum non-esterified fatty acids level was lower (P < 0.0001) in the NanoCr groups. Serum chromium concentration was increased by dietary chromium supplementation, and the chromium source, nanoparticle size and their interaction effects (P < 0.001) were observed. The average back fat thickness in the CrPic and NanoCrPic groups was lower (P < 0.05) than that of the Control group. Meat chromium content was elevated by dietary chromium supplementation, particularly in the CrPic and NanoCrPic groups (P < 0.05). The chromium source, nanoparticle size and interaction effects between these two factors were observed in serum non-esterified fatty acids and chromium content. The muscle chromium content also affected by chromium source and displayed interaction of source and nanoparticle size. In conclusion, chromium supplementation could increase feed intake and average daily gain, serum and longissimus muscle chromium content, as well as reduce back fat thickness of pigs. In addition, nanoparticle organic trivalent chromium could increase chromium absorbability and decrease serum non-esterified fatty acids concentrations. Organic form was better than inorganic form in chromium absorbability, serum and longissimus muscle chromium content and average back fat thickness.

The effects of post-valve T-caecum (PVTC) cannulation and end-to-side ileo-rectal anastomosis (IRA) on growth performance, nitrogen retention and intestinal fermentation were measured in growing pigs by comparison with a control group of intact animals. There were no differences between PVTC-pigs and intact pigs in growth performance and N balance. In IRA-animals reduced growth (P < 0.01), less efficient feed conversion (P < 0.01) and decreased N retention (P < 0.001) were found. Indices of fermentation measured in deal digesta of PVTC- and IRA-pigs were considerably different. In IRA-animals the concentration of volatile fatty acids (VFA) was about 112–162 mmol/l, higher (P < 0.001) than in digesta of PVTC-pigs (20–31 mmol/l). The molar proportions of acetate and propionate depended (P < 0.01 and P < 0.001 respectively) on the digesta-collection technique. Concentrations and ratios of VFA measured in PVTC-pigs were similar to reported values. Diaminopimelic acid (DAPA) concentration and N:DAPA ratios measured in digesta were significantly (P < 0.05 and P < 0.001 respectively) different between treatments. All digesta variables measured showed increased microbial activity in digesta of IRA-pigs; thus, an influence on digestibility measurement can be assumed.

Because chromium is a mineral that is difficult to absorb, nanotechnology was used to produce nanoparticle trivalent chromium, which has a reduced particle size and increased surface area to increase chromium bioavailability. The aim of the present study was to investigate the effect of dietary supplementation nanoparticle trivalent chromium with or without γ-polyglutamic acid (γ-PGA) on the chromium bioavailability, growth performance, serum parameters and carcass traits of pigs. In Trial 1, eight growing pigs (Landrace × Yorkshire × Duroc; LYD) with an initial average weight of 51.3 ± 2.0 kg were used in a 4 × 4 Latin square design as the control group (without chromium supplements), the chromium picolinate group (CrPic), the nanoparticle chromium picolinate group (NanoCrPic) and the nanoparticle chromium picolinate mixed with γ-polyglutamic acid (NanoCrPic–PGA) group. Chromium was added at a level of 200 μg/kg to a basal diet containing 728 µg Cr/kg DM, using different forms of chromium, so as to evaluate the chromium bioavailability. The results of Trial 1 indicated that the bioavailability of the supplemented chromium was as follows: NanoCrPic–PGA &gt; NanoCrPic &gt; CrPic (P &lt; 0.05). In Trial 2, 64 LYD growing pigs (average bodyweight 74.46 ± 3.9 kg) were randomly allotted to the same four dietary treatment groups as in Trial 1 and the same levels of chromium were added to the diet. Each group contained four pens and there were four pigs in each pen. The experimental results indicated that the gain:feed ratio in the NanoCrPic–PGA group was better than that in the NanoCrPic group (P &lt; 0.001). The serum chromium concentrations in the NanoCrPic–PGA group were higher than in the control group (P &lt; 0.05), the serum insulin concentration in the chromium supplementation groups was lower than that in the control group (P &lt; 0.05), and blood glucose in the NanoCrPic group was lower than that in the control group (P &lt; 0.05). The carcass traits were not affected by chromium supplementation. In conclusion, nanoparticle trivalent chromium, either alone or together with γ-PGA, improved chromium bioavailability and feeding effectiveness.

Abstract Recent data show that dried larvae of darkling beetles (Zophobas morio L., DZML) and dried larvae of wax moths (Galleria mellonella L., DGML) contains a significant amount of protein, fat, chitin, melanin, antimicrobial peptides, trace elements etc. Larva’s fat is rich in lauric and other medium-chain fatty acids. The aim of our research was to study the influence of dietary replacement of fishmeal (FM) by insect meal on growth performance and nonspecific immunity of growing pigs. Experiments were performed using crossbred [(BWxL)xD] pigs (BW1=14.39±0.19 kg, N=27, n = 9) during the growing period. Animals were allocated to 3 groups: 1 – control (standard feed (SF), including FM), 2 – experimental (SF+2.5%DZML), 3 – experimental (SF+3.0%DGML). The materials obtained in the experiment was biometrically processed using the ANOVA method (at P &gt;0.05 or P &lt; 0.05). The use of DZML&DGML in feed didn’t reduce ADG of experimental animals during the growing period (413.23&413.76 vs. 413.76 g) compared to the control group. Dried larvae supplementation didn’t reduce feed intake and nutrient digestibility. The fat digestibility increased in the 2&3-experimental group (45.0&44.36 vs 29.75%, P &lt; 0.05), due to the high level of lipids and the profile of fatty acids in the larvae. Biochemical blood test showed a higher ALB/GLB ratio (0.85&1.43 vs 0.59, P = 0.05), higher number of WBC (12.36&12.89 vs. 10.44, P = 0.19) in the blood of the experimental animals compared to the control group. Growing pigs of the experimental groups had a higher level of nonspecific immunity, which is expressed in an increase in bactericidal, lysozyme activity of blood serum and phagocytic activity of neutrophils. Consequently, it is possible to consider the prospects of using DGML&DGML as dietary supplements to diets of growing pigs.

Adipose tissue is an endocrine organ and has central role in interaction with other organs or tissues while propolis can induce lipolysis. Therefore, the aim of this study is to provide detailed information about adipose tissue homeostasis modifications and body composition during propolis supplement consumption. Twenty male Wistar albino rats (8 weeks) were divided into two groups of 10 animals each and fed for 90 days with two different types of diets: standard for the control group (diet C) and standard diet + 2% propolis (diet P). Thyroid hormones did not show differences, while ghrelin and adiponectin decreased in the group that was fed propolis. Insulin, leptin, and non-esterified fatty acids also increased along with reduced body weight and fat, in addition to increased lean mass when propolis was in the diet. We conclude that propolis could decrease ghrelin and adiponectin but increase non-esterified fatty acids and insulin secretion, which improves body composition.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

Abstract Objectives were to determine the effects of rapamycin on biomarkers of metabolism and inflammation during acute heat stress (HS) in growing pigs. Crossbred barrows (n=32; 63.5±0.8 BW) where blocked by BW and randomly assigned to 1 of 4 therapeutic-environmental treatments: 1) thermoneutral (TN) control (n=8; TNCtl), 2) TN and rapamycin (n=8; TNRapa), 3) HS control (n=8; HSCtl), or 4) HS and rapamycin (n=8; HSRapa). The trial consisted of 2 experimental periods (P). During P1 (10d), pigs were fed ad libitum and housed in TN conditions (21.3±0.01°C). During P2 (24h), HSCtl and HSRapa pigs were exposed to constant HS (35.5±0.1°C); while TNCtl and TNRapa remained in TN conditions. Rapamycin (0.15 mg/kg BW) was orally administered twice daily (0700 and 1800 h) during P1 and P2. HS increased rectal temperature, skin temperature, and respiration rate compared to TN counterparts (1.28°C, 8.68°C, and 87 bpm, respectively; P&lt; 0.01). Feed intake (FI) markedly decreased in HS relative to TN treatments (64%; P&lt; 0.01). Additionally, pigs exposed to HS lost BW (4 kg; P&lt; 0.01), while TN pigs gained BW (0.7 kg; P&lt; 0.01). Overall, circulating white blood cells decreased in HS compared to TN pigs (19%; P=0.01). Circulating neutrophils did not differ across treatments; however, lymphocytes, monocytes, and basophils decreased in HS relative to TN pigs (23, 33, and 38%, respectively; P≤0.07). Despite marked changes in phenotypic parameters, circulating glucose and blood urea nitrogen did not differ among treatments (P &gt;0.10). However, insulin:FI increased in HS relative to TN treatments (P=0.04). Plasma non-esterified fatty acids (NEFA) increased in HS relative to TN treatments; although this difference was driven by increased NEFA in HSCtl compared to TN and HSRapa pigs (P&lt; 0.01). In summary, pigs exposed to HS had altered phenotypic, metabolic, and leukocyte responses; however, rapamycin administration had little to no effect on any of the variables measured.

In this trial study, the effect of the vaccination of growing/fattening pigs against Aujeszky's disease virus (ADV) was investigated, in a farm placed in an endemic to ADV area. Three different trial groups of 11-week old growing pigs were vaccinated either once or twice or left unvaccinated. Comparisons between groups were made with respect to growth parameters, carcass quality, as well as pathological and bacteriological findings. All vaccinated animals had significantly better growth performance and carcass quality in comparison to the unvaccinated group, while no significant differences were observed between once and twice vaccinated animals. Lower lungs' affection due to secondary pathogens was also observed in vaccinated groups when compared with the control group of pigs. Bacteriological examination revealed that the frequency of secondary pulmonary bacterial infections, such as Streptococcus suis and Pasteurella multocida was lower in vaccinated pigs compared to controls. It was concluded that single and probably double vaccination against ADV may improve growth performance and carcas quality and may reduce lung affection due to certain secondary pathogens, under the management conditions of the trial farm.

SUMMARY Changes in the plasma levels of non-esterified fatty acids (NEFA) in a group of patients with proven hypopituitarism have been compared with those found in control subjects during prolonged fasting, after the injection of insulin and after the oral administration of glucose with and without the previous administration of insulin. During a 4 hr. prolongation of an overnight fast plasma NEFA levels increased at a significantly slower rate in the patients with hypopituitarism. The intravenous injection of insulin was followed by a prompt fall in NEFA levels in the control group, and by a rapid return to or above original values. The recovery was consistently and markedly impaired in the patients with hypopituitarism and this abnormality differentiated them more clearly from the normal subjects than the abnormality in their plasma sugar response to insulin. The patients with pituitary hypofunction had a flat plasma sugar curve after the oral administration of glucose, but there were only minor differences from the normal plasma NEFA levels. Previous insulin administration impaired glucose tolerance in normal subjects and resulted in a more rapid late return of NEFA levels than after the administration of glucose alone. This late rise in NEFA did not occur in the hypopituitary group. The results obtained support the concept that pituitary integrity is required for normal fat mobilization. The consistency of the changes suggests that tests based on plasma NEFA measurements may provide a useful indirect means of diagnosing pituitary hypofunction.

Abstract The aim of this study was to evaluate the combined effects of trivalent chromium and camelina meal on proximate composition, mineral content and fatty acids profile of broiler chicken thigh meat. An experiment with 2 x 3 factorial arrangement was performed on 240 Ross 308 broiler chicken aged 14 days. Six dietary treatments were elaborated as follows: 0 and 3% inclusion rate of Camelina meal and 0, 200 and 400 μg/kg chromium picolinate (CrPic). Supplementation of broiler diets with 3% Camelina meal led to significantly (P<0.05) increased crude fat concentrations in thigh samples compared to control group or with single chromium supplemented groups. In thigh samples, Zn and Fe concentrations increased under CrPic influence and fatty acids profile was influenced by Camelina meal presence in the diets. In Camelina meal supplemented groups, were registered significantly increased omega 3 fatty acids concentrations compared to control group or single chromium supplemented groups. The results of the present study found that Camelina meal and chromium picolinate supplements in broilers diets improved the nutritional properties of thigh meat, especially essential minerals content and fatty acids profile.

Abstract Background Short-chain fatty acids including butyrate have received increasing research interest as potential alternatives to antibiotic growth promoters (AGP) in animal production. This study was conducted to evaluate the effects of supplementation of sodium butyrate (SB) on the growth performance, rumen fermentation, antioxidant capacity, and immune response of calves before weaning. Healthy Holstein female calves (4-day-old; 40 ± 5 kg of body weight) were randomly allocated to 1 of 4 treatment groups (n = 10 per group). The control group was fed no SB (SB0), while the other groups were supplemented with 2% (SB2), 4% (SB4), or 6% (SB6) of SB/kg of dry matter. All calves were housed in individual hutches. Results The SB supplementation enhanced growth rate and improved feed conversion into body weight gain compared with the SB0 group. At 60 days of age, the rumen fluid pH increases quadratically with increased SB supplementation, and the ammonia nitrogen (NH3-N) concentration of rumen fluid in the treatment groups were significantly lower than that of the SB0 group. There was a quadratic effect that indicated that the SB4 treatment was most effective in reducing the NH3-N concentration. The concentration of volatile fatty acids and Acetic: Propionic in rumen fluid were not affected by SB in any groups. At 28 days of age, the serum level of maleic dialdehyde of the SB groups was significantly lower than that of the control group, and the glutathione peroxidase activity in the serum of group SB4 was significantly increased compared with the that of the control group. At 28 days of age, SB had a quadratic effect on serum immunoglobulin A concentration, with the greatest increase being observed in group SB4. At 60 days of age, the serum immunoglobulin G concentration increased linearly as SB levels increased. Conclusions Under the conditions of this study, there were positive effects of SB supplementation on growth performance, rumen fermentation, antioxidant ability, and immune function in calves before weaning. We recommended 4% as the optimal SB supplementation level to improve growth, antioxidant and immune function of calves before weaning.
