Background: This study was conducted to evaluate the effect of dietary LJP supplementation on growth performance, heat stress resistance and immune status of weaned piglets raised in a high-temperature environment (34 ± 3°C).Methods: A total of 72 Barkshire × Licha Black crossbred piglets were weaned at 30 days of age (BW, 5.88 ± 0.16 kg) and fed either without or with 100, 200 or 400 mg/kg LJP in a completely randomized design, with 3 pens per diet (6 pigs per pen). On day 21, a total of 12 piglets were selected to collect blood samples.Result: The results showed that 200 and 400 mg/kg LJP supplementation decreased the feed conversion ratio (FCR) of piglets compared to the control group (P = 0.037) and dietary LJP linearly increased average daily gain and decreased FCR of piglets (P = 0.037 and 0.011, respectively). In addition, adding 100, 200 and 400 mg/kg LJP reduced the serum HSP70 content compared to the control group (P = 0.019) and dietary LJP linearly and quadratically decreased the serum HSP70 content of piglets (P = 0.030 and 0.011, respectively). Moreover, supplementation of 200 mg/kg and 400 mg/kg LJP increased the serum (NO) and nitric oxide acid phosphatase (ACP) content compared to the control group (P = 0.019; P = 0.003) and dietary LJP linearly increased the serum lysozyme, NO and ACP contents (P = 0.039; P = 0.005; P = 0.001). In conclusion, dietary LJP has potential to regulate systemic defence property of weaned piglets raised in a high temperature condition, accompanied by increased growth performance.

Abstract As an alternative to antibiotic growth promoters, live yeast supplementation has proven useful in reducing weaning stress and improving health and performance of piglets. The objective of the study was to evaluate the effect of a high concentrated live yeast product (20 billion CFU/g) supplemented in post-weaning piglet diets without antibiotics. A total of 144 pigs Pietrain × [LW×Landrace] (average initial BW = 8.55 ± 1.5 kg) weaned at 28 days of life were used for a 6-week growth study to determine post-weaning performance. Pigs were assigned to 2 treatments; 0 (Control group; CT) and 1 g of live yeast/kg (Yeast Supplemented group; YS) feed to 12 replicate pens of 6 pigs (3 barrows; 3 gilts). Average daily gain (ADG), feed intake (ADFI) and feed conversion ratio (FCR) were evaluated in pre-starter (days 0–14), starter (days 14–42) and in the whole nursery (days 0–42) periods. Data were analysed with ANOVA using PROC MIXED of SAS according to the completely randomized design. The model included initial BW as a covariant. Differences were deemed statistically significant when P ≤ 0.050 using a one tailed t-test. Live yeast supplementation improved ADG in starter (5.8%; P = 0.034) and in the whole nursery periods (7.0%; P = 0.045) compared with the CT group. Consequently, final BW was also higher in supplemented animals than in the CT (4.5%; P = 0.034). Differences in ADG were associated with differences in ADFI, higher in YS than in the CT group, both in starter (6.4%; P = 0.023) and in the whole nursery period (6.5%; P = 0.030). No differences were observed for FCR, mortality rate, and health incidences between dietary treatment groups. Therefore, supplementation of a live yeast to post-weaned piglets improved growth performance, confirming this product as an alternative to reduce antibiotic usage in nursery piglets.

Abstract The effect of Enterococcus faecium CCM7420 (EF) - enterocin-producing and probiotic strain of rabbit origin, Eleutherococcus senticosus extract (ES) and their combination (ES+EF) was determined on selected bacteria in faeces and caecum content, leukocytes phagocytosis, blood biochemistry and growth performance. Ninety-six weaned rabbits were divided into 3 experimental (ES, EF, ES+EF) and control group (CG). The rabbits in the groups ES and EF+ES were fed commercial diet enriched with E. senticosus extract (30 g/100 kg feed), rabbits in groups EF and CG were fed untreated diet. The rabbits in the EF and ES+EF groups were administered with an overnight culture of E. faecium CCM7420 strain (500 μl/animal/day into water, 109 CFU/ml). The treatment period lasted 21 days. The microbiological examinations in faecal samples confirmed the presence of E. faecium CCM7420 strain. In groups EF and ES+EF, the reduction of faecal coliforms, Pseudomonas-like sp., Clostridium-like sp. and S. aureus was recorded. Leucocyte phagocytosis significantly increased in all experimental groups (P<0.0001) compared to CG. The lowest GPx values were measured in the ES+EF group. Higher total protein, triglycerides and calcium concentrations were detected in experimental groups compared to CG. The cholesterol concentration decreased in the ES group. The highest average daily gain was recorded in EF group; in ES+EF the better feed conversion ratio and no mortality was recorded. These results indicated that the dietary supplementation with the E. faecium CCM7420 and E. senticosus extract stimulate the leukocytes phagocytosis and reduces the potential pathogens in rabbits digestive tract without oxidative stress and improve the growth performance.

This study aimed to assess the effects of different levels of Trichanthera gigantea leaf meal (TGLM) supplementation on the growth performance of Philippine Native chickens fed commercial chicken grower ration. A total of 96 three-month old native chickens of two sexes were randomly distributed to the four treatments with 3 replicates and 4 chickens per replicate in a 2 x 4 factorial in Completely Randomized Design (CRD). Under semi-confinement system, the dietary treatments consisted of 0, 5, 10, and 15% levels of TGLM supplementation for 13 weeks. Results revealed that cumulative voluntary feed intake (VFI) increased as TGLM supplementation increased, and was significantly highest with 15% level at weeks 10, 11 and 12. Although differences were not significant except at weeks 4 and 7, there was a decreasing trend in cumulative weight gain (CWG) with increasing TGLM level. Average daily gain (ADG) was not significantly affected by varying levels of TGLM supplementation, and feed conversion efficiency (FCE) showed a decreasing trend as TGLM level increased and was only significantly low (p<0.01) with 15% level at week 7. Comparing between sexes, the males were significantly higher than females in all production performance parameters. Therefore, TGLM is palatable but not adequate enough to supply the nutrients needed for a comparable weight gain with that of 0% supplementation, and a 5 10% inclusion in the diet is recommended.

Abstract BackgroundEconomic benefit is an important goal pursued by animal husbandry industry. The emergence of antibiotics has promoted the development of animal husbandry, but many problems caused by the abuse of antibiotics have caused concerns about the use of antibiotics from all walks of life. Therefore, it is imperative to find alternatives to antibiotics. A large number of studies have shown that plant extracts and probiotics have certain potential in improving animal growth performance, antioxidant capacity and immune function. The purpose of this study was to explore the effects of Yucca Shidigera Extract (YSE) and Candida Utilis (CU) on weaned piglets. We compared and evaluated the effects of YSE and CU on weaned piglets from the aspects of growth performance, immunity, antioxidant function, ileal morphology and microflora changes. Forty 28-day-old healthy weaned piglets (Rongchang pig×Landrace×Large white) were randomly divided into 4 treatments: (1) control group (CON); (2) CU; (3) YSE; (4) CU+YSE. ResultsOur results showed that YSE and CU improved the growth performance by significantly increasing final weight, average daily gain (ADG) (P < 0.05), and there is decreasing trend of feed/gain ratio (P=0.087). The effect of adding YSE or CU alone on growth performance had little difference, and the effect of oral CU was slightly better than that of adding YSE. At the same time, the combination of YSE and CU had a good effect on reducing the diarrhea rate. In addition, both YSE and CU increased the diversity of cecal microflora, and CU increased the diversity more significantly, but did not change the dominant microflora of cecum. We also found that the addition of YSE and CU could maintain the structural integrity of intestinal tissue and regulate intestinal pH, to maintain the level of intestinal-associated immune proteins. At the same time, YSE and CU have certain benefits in regulating intestinal flora. ConclusionYSE and CU can improve the growth performance, reduce the diarrhea rate, improve intestinal health, and increase the diversity and abundance of cecal microflora in weaned piglets. Therefore, they are expected to be used as probiotics in the production of weaned piglets.

This study assessed the feasibility of using a vegetable extract, MGM-P (quebracho tannin product), as an alternative to antibiotics for weaned piglets; it investigated MGM-P effects on growth performance, diarrhea, and overall health in early-weaned piglets. In total, 24 piglets were allocated to three treatment groups fed basal diets supplemented with 0, 0.2%, or 0.3% MGM-P for 20 days. The addition of 0.3% MGM-P to the diet of early-weaned piglets improved diarrhea incidence, hematological parameters, and intestinal mucosa structure. Furthermore, the addition of 0.2% or 0.3% MGM-P to the diet of early-weaned piglets did not affect their overall health. Importantly, MGM-P had no effects on average daily gain (ADG), average daily feed intake (ADFI), or feed conversion ratio (FCR). Gut morphology analysis showed that treatment with 0.3% MGM-P enhanced the jejunal villus height (p < 0.05) while reducing the ileal crypt depth (p < 0.05) and colon mucosal thickness (p < 0.05). Collectively, the findings suggested that the use of MGM-P as an alternative to dietary antibiotics could improve diarrhea incidence in early-weaned piglets without negative effects on growth performance or overall health.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

Background: This study was conducted to evaluate the effects of different levels of citric acid (CA) on the growth performance, nutrient digestibility and gastrointestinal pH of weaned piglets. Methods: A total of 120 weaned piglets with an initial BW of 7.15±0.01 kg, were randomly divided into four groups including control treatment each with three replicates of 10 piglets each. Each group was supplemented with 0.5% (control group), 1%, 1.5% and 2% CA in the basal diet, respectively. Result: The results showed that the average daily feed intake (ADFI) and average daily gain (ADG) of added 1% CA group were significantly higher than that of 0.5% group (P less than 0.05). Dietary CA significantly improved the utilization rates of crude protein, calcium and phosphorus (P less than 0.05), while there was no significant difference between adding 1% and 1.5% CA (P greater than 0.05). Compared with the control group, adding CA effectively reduced the pH of the stomach, duodenum jejunum and ileum contents and adding 2% CA were significantly lower than those in other groups (P less than 0.05). Therefore, the addition of 1.0% CA in the diets of weaned piglets is suitable.

The study aimed to evaluate growth performance of grower pigs fed fermented liquid potato hash with or without exogenous enzyme. Diets containing either 200 (LFLPH) g/kg potato hash (enzyme treated or not); 400 (HFLPH) g/kg potato hash (enzyme treated or not) or no fermented potato hash (control) were formulated to provide 14 MJ/kg digestible energy (DE), 180 g/kg crude protein (CP) and 11.6 g/kg lysine. Dietary treatments were control (no FLPH), enzyme treated LFPHE and HFLPHE, and untreated LFLPH and HFLPH. The exogenous enzyme was added in treated diets to provide minimum of 560-840 TXU/TDU xylanase per kg feed, at an inclusion rate of 100 g/tonne. Diets were mixed with water at 1:2 ration and fermented for 8 hours at 25 °C room temperature before being fed to pigs. Back-slopping fermentation approach was followed to prepare diets. Twelve pigs (25±2.3 kg) per diet that were individually housed were fed ad-lib for eight weeks. Pigs were allocated to diets in complete randomized design. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured. The enzyme treated FLPH diets had higher (P < 0.05) CP, lower (P > 0.05) NDF and ADF concentrations compared to untreated FLPH diets. The LFPHE diet had higher (P < 0.001) final weight, ADG and lower (P < 0.001) ADFI and FCR compared to LFPH, HLFPH and HLFPHE. It was concluded that LFPHE diet may be an alternative feed source for growing pigs as indicated by higher gain and lower intake compared to LFLPH, HFLPH and HFLPHE.

To investigate the effect of lipopolysaccharides (LPS) on the growth performance, nitrogen metabolism and immunity in preruminant calves, forty Chinese Holstein male calves were randomly divided into two groups and injected intraperitoneally with 2.5 mg/kg BW of sterile saline or E. coli LPS (Escherichia coli O55:b55) on day 24, 26, and 28. The LPS challenge decreased average daily gain and feed conversion efficiency compared with control group (p less than0.05). The urinary concentration of nitrogen (pless than0.05) increased, whereas the nitrogen retention decreased (pless than0.05) after LPS-challenge. Injection of LPS increased body temperature, serum concentration of IL-1, TNF-a, IL-2 and IgG of calves. In conclusion, LPS-challenge activated immune responses, decreased utilization efficiency of nitrogen, and negatively impacted growth performance of preruminant calves.

This study was conducted to investigate the effects of rumen-protected methionine and α-tocopherol (RPMT) on growth performance, carcass characteristics, and meat composition of late fattening Hanwoo steers in high-temperature seasons. Fourteen steers were randomly assigned to one of two diets; control (commercial concentrate) and treatment (commercial concentrate + 20 g of RPMT). Average daily gain was 34% higher in the treatment group than in the control group; however, there was no significant difference due to the small number under investigation. Feed conversion ratio was lower in the treatment group than in the control group (p < 0.05). Supplementation of RPMT had little effect on the fatty acid composition of longissimus muscle. Metmyoglobin in the longissimus muscle was significantly lower in treatment group compared to the control group at the ninth day of storage (p < 0.05). The redness of the longissimus muscle was higher in the treatment group than in the control group on day 9 of storage (p < 0.01). Thus, the results suggest that RPMT have positive effects on growth performance, and Commission Internationale de l’Eclairage color stability in the longissimus muscle of late fattening Hanwoo steers in high-temperature seasons.
