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.

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.

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 A total of 18 sows (Landrace × Yorkshire) with an average body weight of (within 24 h after farrowing) were used for a 5- week experiment to determine the effects of varying dietary Valine, Lysine (V:L) ratios on performance and fecal score in lactating sows and litters. Sows were raised in individual pens, and assigned to one of three experimental diets consisting different concentration of Valine, Lysine ratios (0.83%, 0.85% and 0.88%). sows body weight was significantly improved by 0.85% valine and lysine ratio compared to 0.85% and 0.88%. However, no significant difference were observed on sows body weight loss, back fat thickness, average daily feed intake and days to return to estrus of sows during the three experiment period. In addition, growth performance of piglet weaning weight were significantly improved by 0.85% valine and lysine ratio compared to 0.85% and 0.88%. Morever, piglet average daily gain was significantly increased 0.88% valine and lysine ratio compared to 0.83% and 0.85%. The three dietary treatments had a significant differences (P&gt;0.05) on fecal score of sows, farrowing and 14 d old age piglets were significantly observed by valine and lisiune ratio. In conclusion, Valine, Lysine had no positive effects on the fecal score of sows and litter during lactation and also no positive effect on gut and its microflora.

Abstract. In the modern broiler industry, solutions are still being sought to improve conditions or eliminate problems related to issues such as animal welfare, health, and meat quality brought by intensive production systems. Therefore, this experiment was conducted to study effects of perching on growth performance, carcass characteristics, and footpad lesions (FPLs) in broiler chickens. A total of 300 broiler chicks (Ross 308) were distributed into control and perch groups with three replicates including equal numbers of males and females. The perch group contained two single perches in each pen. Analysis of camera records revealed that on average 7.36 % of the birds using perches. Perch use did not have any effect on growth performance (P  >  0.05), but had a positive effect on FPLs (P  <  0.001). Carcass yield and proportions of carcass parts were not affected by perch availability (P  >  0.05). Thigh and breast meat color was less yellow (P  <  0.005) in the perch group compared to the control group, where breast meat color was more red (P  <  0.01). Birds in the perch group had brighter breast meat (P  <  0.001). The weight of livers in the perch group was lower than in the control group (P  <  0.01). These findings suggest that perch use has positive effect on FPLs. The reduction of redness in the breast could indicate that perch use may have a positive effect on breast inflammation. The potential positive effects of adapting perch use to intensive conditions should be further investigated.

We assessed the growth performance, physiological traits, and gene expressions in steers fed with dietary rumen-protected L-tryptophan (RPT) under a cold environment. Eight Korean native steers were assigned to two dietary groups, no RPT (Control) and RPT (0.1% RPT supplementation on a dry matter basis) for six weeks. Maximum and minimum temperatures throughout the experiment were 6.7 °C and −7.0 °C, respectively. Supplementation of 0.1% RPT to a total mixed ration did not increase body weight but had positive effects of elevating average daily gain (ADG) and reducing the feed conversion ratio (FCR) on days 27 and 48. The metabolic parameter showed a higher glucose level (on day 27) in the 0.1% RPT group compared to the control group. Real-time PCR analysis showed no significant differences in the expression of muscle (MYF6, MyoD, and Desmin) metabolism genes between the two groups, whereas the expression of fat (PPARγ, C/EBPα, and FABP4) metabolism genes was lower in the 0.1% RPT group than in the control group. Thus, we demonstrate that long-term (six weeks) dietary supplementation of 0.1% RPT was beneficial owing to enhanced growth performance by increasing the ADG and glucose level, decreasing FCR, and maintaining homeostasis in immune responses in beef steers in a cold environment.

Eighty gilts were supplemented with modified tall oil (MTO), chromium nicotinate (CrNic), and L-carnitine to determine effects on growth and meat quality characteristics. Pigs were assigned to one of eight treatments in a 2 × 2 × 2 factorial with main effects of MTO (0 or 0.5%), CrNic (0 or 50 μg kg-1), and L-carnitine (0 or 50 mg kg-1). Pigs fed MTO had increased (P = 0.03) average daily gain and pigs fed CrNic had improved (P = 0.02) gain:feed. Bellies from pigs supplemented with MTO with no CrNic were firmer (P < 0.05) than bellies from all other treatment combinations. No differences (P > 0.05) were detected for longissimus muscle (LM) visual or objective color values. Furthermore, no differences (P > 0.05) were detected for LM Warner-Bratzler shear force or sensory traits. Bacon from pigs fed MTO had firmer (P < 0.05) slices than bacon from pigs fed no MTO.These data suggest improvements in growth performance from addition of 0.50% MTO and(or) 50 μg kg-1 CrNic to diets of finishing gilts. Supplementing with MTO, CrNic, and L-carnitine had minimal effects on carcass, LM color and sensory, or bacon characteristics.

To overcome the loss in terms of mortality and morbidity as the result of the restriction of in-feed antibiotics, many alternatives have been proposed. Yeast cultures as feed additives have various physiological activities in ruminants. Supplementing yeast makes it possible to stimulate the growth of specific rumen microorganisms which ultimately improves the growth of ruminants. This study was designed to analyze the potential effect of green culture, a feed supplement with fermented yeast, in growth performance and immune status of Hanwoo steers. A total of 30 animals were divided into two experimental groups: Control and Green Culture. For each group, five pens were used. Three 6 to 8 months old Hanwoo steers were housed per pen. In-vitro rumen fermentation by the green culture was done to generate base evidence to reflect the In-vivo field trial results. It was found out that, the average daily gain of the treatment group (0.93±0.04kg) supplemented with green culture was significantly higher (p-value less than 0.05) than that of the control group (0.84±0.10kg). In-vitro, ruminal fermentation analysis showed that the total volatile acid content increased with the addition of green yeast culture. These results suggested that the ruminal digestibility of nutrients improved which is reflected in the increase in body weight. Moreover, there was an increase of acetic acid production, in the treatment group supplemented with GC, which is reported to be related to the formation of lipid precursor cells. Therefore, green culture seems to improve the growth of Hanwoo steers as well as their meat quality.

Abstract Objectives were to determine the effects of implants on growth performance, carcass characteristics, and estradiol-17β (E2) concentrations in the serum and longissimus muscle of Holstein steers fed a grain-based diet. Seventy Holstein steers (initial BW = 275 ± 6.4 kg) were assigned to treatments: (1) Implanted on d 0 with Component TE-IS with Tylan (Elanco Animal Health, Greenfield, IN) and on d 84 with Component TE-S with Tylan (Elanco Animal Health) of the experiment; or (2) not implanted (control). Implanted Holstein steers were heavier (P ≤ 0.01) than nonimplanted Holstein steers on d 84, at time of reimplant, and at the end of the experiment (d 186). Implanting Holstein steers increased (P &lt; 0.01) average daily gain (ADG) and dry matter intake (DMI) without affecting (P = 31) gain-to-feed ratio (G:F) when compared to steers that were not implanted. Carcasses from implanted Holstein steers had greater (P &lt; 0.01) hot carcass weights (HCW) and longissimus muscle (LM) area than carcasses from nonimplanted steers. Implanting did not affect (P ≥ 0.21) other carcass characteristics. There was an increase (P = 0.03) of 1.3 pg of E2/g of muscle when LM from implanted Holstein steers was compared to LM from nonimplanted steers. There was an implant × day interaction (P &lt; 0.01) in circulating serum E2 concentrations. Serum E2 concentrations remained relatively constant in nonimplanted Holstein steers. In implanted steers, serum E2 concentrations increased (P &lt; 0.01) after each implant. Serum E2 peaked at 28 d after the first implant and then declined after d 56. Implanting Holstein steers fed grain-based diets increased ADG, HCW, and LM area due to increased circulating E2 concentrations. Implants did increase LM E2 concentrations; however, changes were minimal compared to E2 concentrations in other human foods and were not great enough to warrant concerns regarding meat consumption from implanted animals.
