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.

Aujeszky’S Disease

The consequences of infection by Suid herpesvirus type 1 (SuHV-1) that causes Aujeszky’s disease (AD) are well studied, however, the effects of immunomodulators (IMs) of microbial origin (viral and bacterial) when administered solely or in combination with the attenuated SuHV-1 vaccine are less known. The effects of parenteral administration of IMs, inactivated Parapoxvirus ovis (P. ovis) or a combination of inactivated Propionibacterium granulosum (P. granulosum) and detoxified Escherichia coli lipopolysaccharide (LPS) and attenuated SuHV-1, strain Bartha, on the proportion of peripheral blood CD3- CD21+ B cells were analysed in 30 crossbred, 3-month old pigs using flow cytometry (FCM). Specific antibodies for gE and gB of SuHV- 1 were detected using the enzyme-linked immunosorbent assay (ELISA). Data were compared among six experimental groups: (1) pigs that separately received the vaccine, (2) IM of bacterial origin, (3) IM of viral origin, (4) simultaneous administration of the vaccine and bacterial IM, (5) simultaneous administration of the vaccine and viral IM, and (6) the control group of untreated pigs. Comparison of B cell proportions and the detection of specific antibodies in blood samples of vaccinated pigs on Day 11 of the experiment showed a transient decrease in B cell contents, though this could not be assumed to be related since the control group showed a decrease in B cell proportion on the same day. The results showed that the use of IMs alone or in combination with the attenuated SuHV-1 vaccine did not have a significant impact on the proportion of peripheral blood B cells in growing pigs.

The aim of this study was to evaluate the effect of dietary L-carnitine supplementation either with or without extra Fe supplementation from Fe-amino acid (Fe-AA) complex on body weight gain, feed conversion, carcass characteristics and blood metabolite concentrations in fattening pigs. The study was carried out with 75 fatteners (30.100 kg body weight), divided into three groups, of 25 pigs each. The control group was given a basal diet that contained 85 mg/kg of Fe from premix. A L-carnitine group was given a basal diet supplemented with 100 mg/kg of L-carnitine, and a L-carnitine+Fe group was given a basal diet supplemented with 100 mg/kg of L-carnitine and 60 mg/kg of Fe from a Fe-AA complex. The supplement of L-carnitine to the diets did not have any effects on the growth performance and carcass traits. The L-carnitine supplement decreased the concentration of triglycerides (p.0.05), cholesterol (p .0.05) and low-density lipoproteins (p .0.01) in the blood serum of pigs, while it increased (p.0.01) the concentration of high-density lipoproteins. The combination of L-carnitine+Fe increased the growth performance of growing pigs (p .0.05) and the lean percentage and fatless ham weight in carcass and also increased (p .0.05) the Fe content in the blood serum and the longissimus dorsi muscle of pigs. The results suggest the more effective outcomes can be reached when L-carnitine+Fe rather than only L-carnitine is used in diets.;

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.

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

Thyroid function and morphology, liver morphology, some metabolic indices, haematological parameters and growth performance of fattening pigs fed 00-rapeseed meal (00-RPM) were examined. The control group was fed on a standard diet containing 6% sunflower seed meal (SM) during the growing period and 8% during the finishing period. The first experimental group was fed a diet in which SM was replaced by equal (6% and 8%) amounts of 00-RPM. The second experimental group was fed with a higher (8% and 10%) amount of 00-RPM. There were no significant differences between the control and experimental groups in the serum concentrations of triiodothyronine (T3) and thyroxine (T4). Thyroid gland and liver weights were significantly (P < 0.01) higher in both groups fed 00-RPM than in the group fed SM. The epithelium of the thyroid gland was cuboidal or columnar and the follicular area was moderately enlarged in pigs fed 00-RPM. Marked changes in liver histology were not observed. The 00-RPM diet increased (P < 0.01) the serum values of total proteins in the first fattening period. At the end of fattening both groups fed 00-RPM had higher (P < 0.05; P < 0.01) concentrations of plasma glucose than the control group. The inclusion of 10% of 00-RPM during the finishing period increased (P < 0.05) the serum values of insulin. Daily weight gain during the growing and the finishing period was higher (P < 0.05) in the experimental groups than in the control group. The results suggest that 6-10% 00-RPM can be used as a protein source in the diet of fattening pigs without poisonous side effects.

Encoding Genes

Chronic heat stress (CHS) induces metabolic changes in skeletal muscle from growth to maintenance that jeopardizes growth performance, carcass traits, and meat quality of pigs. We investigated the protective effect of dietary organic selenium (hydroxy-4-methylselenobutanoic acid, OH-SeMet) on CHS-induced skeletal muscle damages of growing pigs, and the corresponding responses of selenoproteins. A total of 40 ((Landrace × Yorkshire) × Duroc) pigs with an average live weight of 49.64 ± 2.48 kg were used in this 4-week trial. Pigs were randomly allotted to 5 groups: The control group was raised on a basal diet in a thermoneutral environment (22 ± 2 °C); and four CHS groups were raised on a basal diet and supplemented with Se 0.0, 0.2, 0.4, and 0.6 mg/kg as OH-SeMet, respectively, in hyperthermal condition (33 ± 2 °C). CHS resulted in significant decrease of growth performance, carcass traits, and meat quality, which were associated with reduced (p < 0.05) serum alkaline phosphatase (ALP) and total superoxide dismutase (T-SOD) and increased (p < 0.05) serum creatine (CK), sarcous heat shock protein 70 (HSP70), glucokinase (GCK), phosphoenolpyruvate carboxykinase (PEPCK), and malondialdehyde (MDA) contents. Meanwhile, four metabolism-related genes and seven selenoprotein encoding genes were abnormally expressed in skeletal muscle. Dietary OH-SeMet addition partially alleviated the negative impact of CHS on carcass traits and improved meat quality. These improvements were accompanied by the increase in Se deposition, the anti-oxidative capacity of serum and muscle, and protein abundance of GPX1, GPX3, GPX4, and SELENOP. Supplementation with 0.6 mg Se/kg (OH-SeMet) restored the sarcous PEPCK, and 0.4 and 0.6 mg Se/kg (OH-SeMet) restored all abnormally expressed metabolism-related and selenoprotein encoding genes. In summary, dietary supplementation with OH-SeMet beyond Se requirement mitigated CHS-induced depression of carcass traits and meat quality of pigs associated with optimal skeletal metabolism, enhanced antioxidant capacity, and regulation of selenoproteins in skeletal muscle of pigs.
