Glutinous Rice

This study investigated the effect of purple glutinous rice bran (PRB) supplementation on performance, oxidative status and lipid oxidation in broiler. Two hundred male day old broiler chickens were randomly assigned to 5 groups of 40 birds each. Each treatment, fed the basal corn-soybean diets containing 0%, 3%, 6%, 9% and 12% of purple glutinous rice bran (PRB). Diets were formulated separately for starter and finisher phases (day 0 to 21 and day 22 to 42). Oxygen radical absorbance capacity (ORAC) in PRB supplemented groups were higher than rice bran group and depend on the supplement dose of PRB. PRB supplementation (6%, 9% and 12%) increased (P less than 0.05) weight gain (WG), average daily gain (ADG) and decreased (p less than 0.05) feed conversion ratio (FCR) compared to control group. Malondialdehyde (MDA) levels in serum from the PRB groups were lower than control group (P less than 0.05). Glutathione (GSH) levels in serum of PRB groups (6%, 9% and 12% PRB) were higher than control group (P less than 0.05). However, there were no difference between 3% PRB and control groups. No difference of lipid oxidation in breast meat after storage between PRB supplemented groups with control group (P>0.05). This study indicated that PRB supplementation in diet had positive effects on performance and oxidative status of broiler chickens but had no effect on lipid oxidation in breast meat storage

A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

Abstract Background: The present study aimed to explore the effects of dietary chitosan oligosaccharides (COs) on the growth performance and immunity of broiler chickens.Methods: Four test diets were supplemented with different doses of COs (0, 50, 100 and 150 mg/kg) and formulated. Triplicate groups of broiler chickens were fed with one of the diets ad libitum for 6 weeks. Results: After the end of the feeding trials, oral CO administration improved average daily gain; the activities of digestive amylase, lipase and protease; the activities of serum superoxide dismutase and glutathione peroxidase; serum tumor necrosis factor-α, interleukin (IL)-1, IL-2, IgG, IgM and IgA levels; and reduced feed conversion ratio and malondialdehyde level compared with those of the control group. However, a high dose of CO (150 g/kg) did not further increase its efficiency compared with the moderate dose of CO (100 g/kg). Conclusions: Oral CO administration improved the growth performance and immunity of juvenile broiler chickens and could be used as a feed supplement.

summaryThe objective of the current study was to determine the applicability of wheat-corn-distillers dried grains with solubles (DDGS) as protein source with and without non-starch polysaccharides (NSP)-hydrolyzing enzymes in diets of broiler chicks. In addition to the performance and carcass characteristics, the effect on energy parameters (energy intake per day, energy per kilogram feed), digestibility, as well as sensory aspects and fatty acid profile of breast meat were determined. In a 3×2-factorial approach, a total of 360 broiler chickens (Ross 308) were allocated to six treatment groups (8%, 16%, and 24% DDGS, with or without NSP-hydrolyzing enzymes). The zootechnical performance was not influenced by increasing DDGS concentrations over the whole fattening period, whereas supplementation of the NSP-hydrolyzing enzyme improved feed conversion ratio in the grower phase and increased average daily gain (ADG) in the finisher phase (p < 0.05). Energy and dry matter (DM) digestibility as well as apparent N retention did not differ between treatments. The substitution of soybean meal and corn with DDGS and vegetable oil showed a trend of increased tenderness of broiler breast meat. Nevertheless, the intramuscular amount of polyunsaturated fatty acids increased with increasing inclusion rate of DDGS and vegetable oil (p < 0.01).

This study was conducted to examine the effect of two humic substances (HS) supplemented in broilers’ diet on the breast meat quality of broiler chickens. In this experiment, 120 pieces of one-day-old COBB500 broiler chickens were used. Broilers were divided into three groups, each containing 40 birds with three replications (13, 13, and 14 per one pen). Fattening lasted 38 days. The first experimental diet was supplemented with 0.7% of HS (HS0.7) and the second was enriched with 0.7% of acidified HS (HSA0.7). The control group of broilers (C) was fed a basal diet without the addition of any supplements. HS0.7 samples had the highest total protein content and the lowest content of fat (p < 0.01). The effects of broiler diet and storage had a significant impact on the pH of breast samples, p < 0.001 and p < 0.05, respectively. Supplementation of HS in broiler diet positively affected the lipid oxidation of breast meat samples, as indicated by the lower malondialdehyde content (p < 0.05). HSA0.7 samples had significantly better juiciness after the storage period (p < 0.001). The quality of meat produced with supplementation of HS in broilers’ feed can be considered as valuable in human nutrition due to improved protein and fat content with decreased lipid oxidation.

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.

Coccidiosis is an infectious parasitic disease of poultry which causes heavy economic losses to commercial poultry industry. Coccidiosis has been generally controlled by using different synthetic anticoccidial drugs but, due to development of resistance to these drugs this method is losing its effectiveness. Exploration of novel and alternative compounds against avian coccidiosis is need of time now a days. In this regard, medicinal plants can serve as substitute to these synthetic anticoccidials. Thus, to find out alternative novel agents, current research was designed to evaluate the anticoccidial potential of Ageratum conyzoides extract (ACE). For in vivo experiment, 105 broiler chicks were purchased and further divided into 7 sub-groups (15 birds in each group). At 7th day of experiment, Groups A, B and C were fed with plant extract at 100, 200 and 300 mg/kg respectively. Group D was supplemented with Vitamin-E while, Group E and F remained as infected medicated and infected un-medicated control groups and served with standard medicine (Baycox®) and Phosphate Buffer Saline (PBS) respectively. Moreover, Group G served as normal control group. At day 14th of experiment, all groups except rom Group G were orally infected with 60,000 sporulated oocysts of mixed Eimeria species. Anticoccidial potential of ACE was evaluated on the basis of lesion scores, fecal scores, oocyst scores and feed conversion ratio. Furthermore, the effect of ACE on the serum chemistry was also evaluated to check toxicity of plant extract if any. The results were compared with standard medicine (Baycox®). On the basis of results, ACE showed anticoccidial activity by reducing fecal, lesion and oocyst scores in infected chicks (P<0.05). ACE also improved FCR of infected chicks. Moreover, ACE exhibited positive effects on serum chemistry of broiler chickens (P<0.05).

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.

This study aimed to investigate whether dietary bile acid (BA) supplements can improve growth performance and lipid metabolism in heat-stressed broiler chickens. A total of 288 Arbor Acres broilers were blocked by BW and then randomly allocated into 4 treatments at 21 days of age. Birds reared under 32 °C had a higher cloacal temperature (p = 0.01), faster respiratory rate (p < 0.001), and a greatly reduced average daily feed intake (ADFI, p = 0.016), average daily gain (ADG, p = 0.006), final body weight (FBW, p = 0.008), and feed conversion rate (FCR, p = 0.004). In heat stress (HS) birds, the breast muscle rate (p = 0.006) and pH 24 h postmortem (p = 0.065) were lower, and the shear force was higher (p = 0.027). Dietary BA supplements tended to increase the breast muscle rate (p = 0.075) without affecting the growth performance and serum lipids (p > 0.05). Serum total bile acid (TBA) was roughly duplicated after BA supplements (p = 0.001). In the liver, total cholesterol was lower (p = 0.046), and triglycerides were higher (p = 0.04) in the HS birds, whereas the expression of SREBP-1c showed an increasing trend (p = 0.06). In contrast, dietary BA decreased triglycerides and the expressions of hepatic SREBP-1c and FAS in the liver (p < 0.05). In summary, mild HS causes hepatic lipid accumulation without obvious tissue damages, whereas BA has positive effects on relieving abnormal lipid metabolism, indicating that BA as a nutritional strategy has a certain potential in alleviating HS.

The use of insects can be a possible source of protein. This study uses Calliphora sp. larvae (CLM) as a protein source in 320 one-day-old medium-growing male chicks (RedBro) during their first month of life. Chickens were randomly assigned to four dietary treatments. Each group consisted of 10 animals, and a total of 8 replicas. Control group was fed with a certified organic feed. The experimental treatments were supplemented with 5% (T2), 10% (T3), or 15% (T4) of CLM, reducing in each case the corresponding percentage of feed quantity. Productive development and meat quality were analyzed, and near infrared spectroscopy (NIRS) was used as a tool for classifying the samples. Chickens of T4 showed greater final body weight and total average daily gain, but they reduced consumption and feed conversion ratio (FCR). The chicken breast meat of T4 had lower cooking losses and higher palmitoleic acid content (p < 0.01). NIRS classified correct 92.4% of samples according to the food received. CLM is presented as a potential ingredient for the diet of medium-slow growing chickens raised in organic systems.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.
