Three experiments were conducted to study growth, incidence of scouring and mortality of 2- and 3-wk weaned piglets fed immunoglobulins (IMG) derived from abbatoir porcine serum. In experiment 1, 20 piglets weaned at 2 wk of age were randomly divided into a control and an IMG-treated group. In both groups 1 × 1012 organisms of a pathogenic strain of Escherichia coli was administered by stomach tube. The IMG-treated group had a faster (P < 0.01) average daily gain, reduced incidence of scouring (P < 0.01) and lower mortality (P < 0.07) than the control group. In experiment 2, 36 piglets weaned at 3 wk of age were allotted to a control and IMG-treated group. In the absence of a loading dose of E. coli there were no significant differences in average daily gain, scour scores or rectal temperature between the control and the IMG-treated groups. In the third experiment, 72 piglets were weaned at 3 wk of age and randomly allotted to three treatments: a control, an IMG-treated and an antibiotic-treated (Neomycin Sulfate) group. The results of the former two groups were similar to those obtained in experiment 2. The antibiotic-treated group had a faster (P < 0.01) gain than both control and IMG group despite the similarity in the incidence of scouring.

The effects of dietary hydrolyzed Chinese gallnut tannic acid(GCT) as a replacement for ZnO were investigated on weaned piglets. A total of 72 weaned piglets at 31 ± 1 day (six replicate pens per treatment with six piglets per pen) were selected and divided randomly into two groups: a control group, with a basal diet of + 1600 mg/kg ZnO; and a treated group, with a basal diet of + 1899.5 mg/kg GCT. Data analysis showed that the significance of average daily gain and average daily feed intake between the two groups was p = 0.731 and p = 0.799, respectively. Compared with the control group, the diarrhea rate of piglets in the treated group underwent no noticeable change on days 0–7 (p = 0.383) and 7–14 (p = 0.263), but decreased significantly on days 14–21 (p < 0.05). Additionally, we found GCT can reduce the crypt depth of the ileum and improve its antioxidant capacity (p < 0.05). High throughput sequencing showed that GCT increased the richness of the bacteria Lachnospiraceae (p = 0.005), Prevotella_2 (p = 0.046) and Lactobacillus amylovorus (p = 0.081), which are associated with the degradation of cellulose and hemicellulose. The study indicated that 1899.5 mg/kg GCT could be an alternative for 1600 mg/kg ZnO in the diet of piglets.

Twenty-six of 52 heifers with an average liveweight of 318 kg were dewormed by intraruminal injection of oxfendazole and placed in drylot on 31 January. The other 26 animals served as controls. All heifers were pastured starting on 14 June and the treatment heifers were dewormed in the same manner as at the start of the experiment (31 January) on 1 July and 31 July. The groups started out with similar total worm eggs per gram of fecal sample, but the dewormed heifers had fewer counts each month thereafter. The drylot average daily gain of the treated heifers was higher (P = 0.01) and less variable (P = 0.12) and by 29 May these animals were heavier by 11.7 kg (P = 0.10). The treated animals did not gain as fast on pasture (P = 0.20), but the gain continued to be less variable (P = 0.09). Age at puberty was not different. Number of open heifers in the treated group was 4 vs. 15% for the control group (P = 0.18). Deworming by intraruminal injection resulted in faster feedlot gains, more uniform gains during both drylot and pasture, reduced parasites and no abscess at injection sites.

The effects of the use of fish meal in the nutrition of weaning piglets were observed. The trial included 80 weaned piglets of the same genotype (Large White x Danish Landrace) distributed in two feeding treatments. In the first period of the experiment, animals were fed during 10 feeding days, with a prestarter mixture containing 21.1/20.8% of the crude protein. The second period lasted for 25 days and piglets were fed with mixture containing also 21.0/21.1% of the crude protein. And in the final period of the experiment, which lasted 22 feeding days, the meals were formulated to contain 19.5/19.9% of the crude protein. The control group was fed with standard farm mixtures, while the trial group were fed with mixtures containing 4/3/2% of fish meal. The obtained results showed that the use of fish meal resulted in better average daily gain and feed conversion in starter period (27-51 day).

SUMMARYThe present study was conducted to determine the effects of a polysaccharide of Atractylodes macrophala Koidz (PAM) as a dietary additive on growth performance, immunoglobulin concentration and IL-1β expression in weaned piglets. One hundred and twenty Landrace×Yorkshire piglets weaned at 28 days old (body weight 7·5±0·07 kg) were assigned to five treatment groups (three pens/group, eight piglets/pen) fed maize/soybean-based diets supplemented with 0, 3, 6 or 9 g of PAM/kg diet or antibiotics (0·4 g flavomycin/kg+0·13 g olaquindox/kg). The experimental period was 28 days. With increasing PAM supplementation levels, average daily gain was greater (quadratic, P<0·05) and the ratio of amount fed to live weight (LW) gain (feed/gain) improved (quadratic, P<0·05) during days 14–28 and overall, and diarrhoea incidence decreased (linear, P<0·05) during days 14–28. Supplementation of PAM also increased (quadratic, P<0·05) serum concentrations of interleukin (IL)-2 and IL-6 on day 14, and increased (quadratic, P<0·05) IL-1β expression in jejunal mucosa and lymph nodes. Concentrations of PAM between 6 and 9 g/kg presented the strongest bioactivity compared to the control group or antibiotic-fed group. These findings indicate that PAM is effective in improving growth performance and cytokine response, which suggests that PAM can be used as a diet additive for weanling piglets.

Abstract Combining natural additives with specific and selected neuro-sensory molecules is a possible solution to manage stress in feedlot beef cattle. The objective of this study was to compare the combination of a neuro-sensory additive (VeO) with a mix of natural additives (Fator P, Premix, Brazil) on behavior and performance. This study was conducted from May to August in the Premix Research Center, Patrocínio Paulista, Brazil. Fator P is made up of amino acids, organic minerals, probiotics, essential fatty acids and surfactant. VeO is based on a specific extract from Rutacea family. 80 Nellore bulls were randomly assigned to a control group (FP) and a treated group with 40 animals in each (10 per pen). Both groups received the same total mixed ration with the addition of a neuro-sensory additive (FPV) as the only difference. Adaptation period was considered as 21 first days out of 100 days total fattening period. Analyzed variables were eating (min/day) and rumination (min/day), average daily gain (g/day), dry matter intake (%BW) and feed conversion. Tukey test was used for comparison of means. During adaptation, animals spent 30.8 % more time ruminating. Feed conversion and DMI with FPV tended to be more efficient by 30.86% (P = 0.074) and 31.16% (P = 0.063) respectively. After 21 days, treated animals continued eating (P = 0.14) and ruminating more as well (P = 0.07). Over 100 days, bulls receiving FPV showed a higher average daily gain by 9.94% (+153 g/day, P = 0.07) consuming less feed per kg of growth (6.46 vs. 7.00; -7.7%; ns). Results showed that the use of the neuro-sensory additive with the mix of natural additives changed behavior of feedlot finishing bulls, leading to more efficient production with an increased average daily gain and an improvement of feed conversion.

The aim of this study was to evaluate the effect of zinc (Zn) supplementation in different commercial forms on the growth performance, health status, and Zn balance of weaners in field conditions. The animals were fed pre-starter (from the 28th to 47th day of life) and starter (from the 48th to 74th day of life) mixtures differing in Zn form and concentration. Group I was given ZnSO4 at 150 mg kg−1; Group II received pre-starter zinc oxide (ZnO) at 3000 mg kg−1 and starter at 150 mg kg−1; and Group III was given 150 mg kg−1 of zinc oxide nanoparticles (nZnO). We found that the average daily gain in Group I was significantly lower, compared to Groups II and III. A commonly accepted level of Zn (150 mg kg−1) as nZnO can be recommended, instead of therapeutic doses of Zn preparations with the same efficiency. Moreover, a lower level of Zn in the diet can prevent the excessive accumulation of this element in waste and, thus, reduce environmental damage.

AbstractThe aim of the study was to assess the gut microbiota and selected haematological and biochemical blood parameters of weaned piglets following dietary supplementation with a probiotic and vitamin C. the piglets were divided into a control group (group C) and an experimental group (group E), with 30 piglets in each group. All animals received the same feed ad libitum. The animals in the control group (group C) received feed with no added probiotic and vitamin C. the piglets in the experimental group (group E) were given a supplement containing a probiotic (Bacillus cereus 1×109 CFU/kg) in the amount of 1.5 g/piglet/day and vitamin c in the amount of 300 mg/piglet/day. The supplement was administered for 28 days. The total numbers of bacteria of the family Enterobacteriaceae and of the genus Lactobacillus were determined in faeces. The erythrocyte count, haemoglobin level, haematocrit, leukocyte count, and percentages of neutrophils and lymphocytes were determined in the blood. The biochemical analysis concerned the concentration of triacylglycerols, total cholesterol, and LDL and HDL cholesterol. In group E a significant decrease (P<0.01) in the total number of Enterobacteriaceae bacteria was observed in the faeces of the piglets, accompanied by an increase in the number of lactobacilli relative to group C. E. coli was found to predominate over other microorganisms. Salmonella choleraesuis bacteria were present in the faeces of both groups before administration of the supplement, but were not found after its use. The supplement with probiotic and vitamin C caused a significant increase in the erythrocyte, haemoglobin and haematocrit levels in the blood of the piglets and a significant decrease in the concentration of triacylglycerols, total cholesterol and LDL cholesterol.

The effect of using different levels guanidinoacetic acid in compound feeds on the growth of young quails meat direction of productivity. It is proved that adding to the basic diet of different levels guanidinoacetic acid (0.06, 0.12, 0.18 %) increases live weight of quails on 3.9 – 13.5 g and improves the absolute, average daily and relative gains compared to a bird in the control group, which were fed the main diet. The data show that at the age of 42 days of live weight was the highest in the diet of quail which was administered 0.12% GAA and dominant control of 13.5 g However, in 21 days live weight of quail fed 0.06 and 0.12 % guanidinoacetic acid was greater than control respectively 9.2 and 7.6 grams (P < 0.01). In absolute increments quail, fed GAA prevailed bird control group. The largest absolute increase was in birds that consumed the main diet of GAA level of 0.12% and prevailed controls 6.5 g (P < 0.001). A similar situation was of average daily gain. Young animals that received feed containing 0.12% guanidinoacetic acid had the highest average growth, which exceeded 0.9 g (15.5%) bird control group. As for the relative performance increases here were different. The lowest relative growth observed in birds which were administered GAA 0.06%, it lagged behind the controls 0.1 g in the same period quail treated with 0.12 and 0, 18% guanidinoacetic acid superior control respectively 2 and 1.1 g.

Stimulation Of

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.
