Effect of Feeding Curd as A Probiotic on Growth Performance, Nutrient Utilization, Blood Biochemical and Ceacal Microbial Profile in Broilers

An experiment was conducted to investigate the effect of curd as probiotic on growth performance, nutrient utilization, blood biochemical and caecal microbial profile in broiler chicken. Day old broiler chicks (n=200) were procured and reared for one week with standard chick mash, and then divided into three dietary treatments having three replicates of 22 chicks in each. The treatment groups were fed the following rations for 42 days; T1 group fed basal diets alone (control), T2 and T3 groups fed basal diet with 10 and 20 percent probiotic product (curd fermented maize). At the end of the feeding experiment, a metabolic trial was conducted to evaluate the digestibility of nutrients. Average body weight change and gain in weight were higher (P

Breast and Thigh Meat Chemical Composition and Fatty Acid Profile in Broilers Fed Diet with Dietary Fat Sources

Experiment was conducted to evaluate effects of different fat sources on breast and thigh meat chemical composition and fatty acid profile in broilers. Treatments were 1) DF1: basal diet + soybean oil; 2) DF2: basal diet + chicken fat; 3) DF2: basal diet + tallow; 4) DF3: basal diet + tallow and lard, and 5) DF5: basal diet + lard. Addition of different fat sources had no significant impact on relative organ weight (P>0.05). Breast meat crude fat content was suppressed in DF1 and DF5 relative to DF4 (P<0.05). Total SFA content was downtrended and total PUFA content was elevated in DF1 relative to other groups for both breast and thigh meat (P<0.05). Total MUFA content did not differ in breast meat however, it was lower in DF1 and DF3 compared to DF2, DF4 and DF5 (P<0.05). The n-3 PUFA was not affected by fat sources in breast meat, whereas it was elevated in DF1 relative to DF3, DF4 and DF5 in thigh meat (P<0.05). Breast and thigh meat n-6 PUFA was improved in DF1 in comparison to DF2, DF3, DF4 and DF5 (P<0.05). Ratio of PUFA to SFA upgraded in DF1 and DF3, and downgraded in DF2, DF4 and DF5 for breast meat; and upgraded in DF1 than other groups for thigh meat (P<0.05). Breast and thigh meat n-6 to n-3 PUFA was upgraded in DF1 group compared to other groups (P<0.05). To sum up, results indicated that dietary fat sources with different fatty acid content can significantly influence the breast and thigh meat composition and fatty acid profile without negative impact on the relative organ weight. Where DF1 group exhibited better result based on fatty acid profile and lower breast meat fat content which can be preferred for quality broiler meat production.

Performance, Immunity, Meat Composition and Fatty Acid Pattern in Broilers after Dietary Supplementation of Fermented Ginkgo biloba and Citrus junos

Dietary Fermented Ginkgo biloba (FGLP) and Citrus junos Probiotics (FCJP) was evaluated on growth performance, immunity, cecal microbiology, meat composition and fatty acid profile in broilers. A total of 150 one day old Ross 308 broilers were randomly allocated to the 5 treatments (5 replicated pen of 6 birds/pen): 1) Control (corn-soybean meal based basal diet), 2) FGLP1: Corn-soybean meal based basal diet+5% FGLP, 3) FGLP2: Cornsoybean meal based basal diet+10% FGLP, 4) FCJP1: Corn-soybean meal based basal diet+5% FCJP, and 5) FCJP2: Corn-soybean meal based basal diet+10% FCJP. A significant increase in weight gain during starter (0-21 days), finisher (22-35 days) and overall period (0-35 days) was exhibited in FGLP2 supplemented group compared to control and other treatment groups (P 0.05); however, among meat fatty acids, sum of SFA in thigh meat was diminished in FGLP group and sum of MUFA in breast meat was diminuted in FGLP and FCJP group compared to control (P<0.05). Sum of n-3 PUFA of breast and thigh meat was elevated after supplementation of FGLP and FCJP compared to control (P<0.05). To sum up, dietary FGLP and FCJP supplementation significantly improved performance and immunity, decreased SFA and elevated n-3 PUFA of broiler meat. Therefore, FGLP and FCJP probiotics could be supplemented as functional feed additives in broilers diet.

Effect of Neem Oil Supplementation on Growth Performance and Hematobiochemical Profile in Broilers

A study was undertaken on one hundred day old broiler chicks to obtain information about safe levels of neem oil supplementation in broiler feed for economic poultry farming. Significant decrease in body weight and feed consumption was observed in birds on addition of 0.4 per cent neem oil. Hematological study revealed non significant difference between treatment group and control group birds. Birds given 0.4 % neem oil showed numerical increased TLC, absolute heterophil and absolute lymphocyte count when compared with control and other treatment group birds (0.1, 0.2 and 0.3 % neem oil). Average plasma glucose level showed dose dependent hypoglycemic response. Serum total protein and serum globulin level showed significant decrease at 0.4 per cent level suggesting adverse effect in broilers. It is thus concluded that neem oil supplementation up to 0.3 per cent in feed could be used safely in broilers.

Effects of dietary Enterococcus faecium on growth performance, carcass characteristics, faecal microbiota, and blood profile in broilers

This research was performed to evaluate the effect of supplementing broiler diets with a probiotic containing Enterococcus faecium on growth performance, carcass characteristics, faecal microbiota, and blood profile. A total of 384 one-day-old Ross 308 broiler chicks (mixed gender) with an average initial BW of 39.2 g were used in a 35 days feeding trial. The chicks were allotted to pens with 16 birds per pen and eight replications per treatment with food and water provided ad libitum. Treatments were: (1) basal diet, (2) 0.25% probiotic, and (3) 0.5% probiotic. Results indicated that body weight gain (BWG) on Day 7 to 21, Day 21 to 35 and overall (0 to 35) increased (P < 0.05) linearly but feed intake (FI) and feed conversion ratio (FCR) were not affected. A linear increase (P < 0.05) was observed in the relative weight of breast muscle when comparing the 0 to 0.5% concentration of probiotic, but breast meat colour was not affected by treatments. A significant impact (linear effect, P < 0.05) was observed on drip loss on Day 1. Inclusion of probiotic decreased (P < 0.05) the count of Salmonella linearly but the counts of E. coli and Lactobacillus were not affected. There was no remarkable influence on blood profile. Thus, it was concluded that inclusion of a probiotic containing Enterococcus faecium improved growth performance and altered the intestinal microbial population, without any negative effects on meat colour and blood profile in broiler chickens.

Parámetros productivos y sanguíneos en pollos de carne suplementados con cocarboxilasa

The aim of this study was to evaluate the effect of cocarboxylase on productive performance, blood glucose and lipid profile in broilers. A total of 11004 one-day-old male broiler chickens were randomly allocated into 1 of 3 treatments with 4 replicates per treatment (917 chickens per replicate) and conventionally reared until 42 days old. The treatments were T1 (Conventional diet), T2 (Modified diet, reducing a percentage soybean oil and the addition of cocarboxylase) and T3 (Modified diet, reducing a percentage soybean oil without cocarboxylase). Broilers supplemented with cocarboxylase (T2) resulted in higher final weight and weight gain compared with the others treatments. The inclusion of cocarboxylase had positive influence on weight, which suggests its usefulness as a partial replacement of the oil used in chicken diets.

Effect of feeding wild sunflower (Tithonia diversifolia) leaf meal (TDLM) on haemato-biochemical profile of broilers reared under deep litter system of management in Mizoram (India)

The effect of feeding wild sunflower (Tithonia diversifolia) leaf meal (TDLM) on haemato-biochemical profiles of broilers was studied. Day old broiler chicks (180) were divided into six homogenous groups and fed rations with TDLM @ 0, 2, 4, 6, 8 and 10% as substitute of conventional ingredients for six weeks. The chicks were reared in battery brooder for first 14 days, and thereafter under deep litter system. Bloods were collected on 14th, 28th and 42nd day of age and haemato-biochemical parameters were estimated utilizing analytical kits. The study revealed that the average daily gain in body weight of broilers decreased with increased inclusion level of TDLM in ration and was significantly reduced above 4% inclusion level. The PCV and Hb values decreased (36.81±0.5131.25±0.70% and 12.47±0.35–9.40±0.71 g dL−1) and total RBC and WBC counts increased [4.20±0.12–6.43±0.09 (x10−6 mL−1) and 4.13±0.13–6.40±0.58 (x10−3 mL−1)] with increased inclusion level of TDLM in ration. All biochemical parameters were variable throughout the feeding trial in all the groups. Total serum protein decreased with increased inclusion level of TDLM indicating alteration of normal protein metabolism. The GPT and GOT levels were higher at higher TDLM level but within the normal range. The serum Ca and P levels were variable but within the normal range. It was concluded that inclusion of TDLM upto 10% level as substitute of conventional ingredients has no significant effect on haemato-biochemical profiles of broilers although body weight gain is significantly reduced above 4% inclusion level of TDLM in the ration.

Effect of supplementation of Withania somnifera (Ashwagandha) root powder as feed additive on performance and blood biochemicals of broilers

An experiment was conducted on one hundred eighty day old commercial broiler chicks (Ven Cob Strain) to study the effect of Withania somnifera (Ashwagandha) root powder as feed additive on the performance and blood biochemical profile in broilers during 0-6 weeks of age. The chicks were randomly divided into three groups 60 each. All the chicks were housed in deep litter system. The experimental diets were: no feed additive (T0), 0.25 per cent Ashwagandha root powder (T1) and 0.5 per cent Ashwagandha root powder (T2). Body weight gain of T1 (567.00 g) and T2 (581.67 g) was significantly (Ps a herbal feed additive was beneficial in improving average weekly body weight gain, feed conversion ratio and blood biochemical profile.

Dietary effects of chitosan and buckwheat (&lt;i&gt;Fagopyrum esculentum&lt;/i&gt;) on the performance and serum lipid profile of broiler chicks

This study was conducted to evaluate the effects of different levels of buckwheat (Fagopyrum esculentum) alone or in combination with chitosan, in broiler diets, on the growth, feed intake and serum lipid profile of broilers. Starting as 10-day olds, 144 Cobb 500 broiler chicks were fed six manually prepared diets containing 0%, 10%, 20% or 30% buckwheat, or 10% buckwheat supplemented with 250 mg chitosan or 500 mg chitosan/kg. The trial lasted 32 days. Buckwheat alone or in combination with chitosan had no effects on the growth and feed intake of the broilers. Until 15 days lipid profiles in blood sera did not change in birds fed buckwheat alone or buckwheat in combination with chitosan. However, at day 30 the inclusion of 10% - 30% buckwheat alone and 10% buckwheat with 250 mg chitosan/kg or with 500 mg chitosan/kg showed a significant increase in serum HDL-cholesterol concentration and a decrease in total cholesterol, triglycerides and LDL-cholesterol concentrations in the serum compared with the control. This demonstrates for the first time that the feeding of higher levels of buckwheat (20% or more) alone or lower levels of buckwheat (10%) with trace amounts of chitosan influenced the lipid profiles of broilers positively. Because hazardous antibiotics are banned in poultry feed, including of buckwheat with trace amounts of chitosan in broiler diets might be a useful alternative to antibiotics in the poultry industry.

THE EFFECT OF SAUROPUS ANDROGYNUS LEAVES EXTRACT PLUS TURMERIC POWDER ON FAT DEPOSITION, CARCASS QUALITY AND BLOOD PROFILE IN BROILERS FED LOW PROTEIN DIETS

The present study was designed to evaluate the effectiveness of Sauropus androgynus leavesextract (SALE) plus turmeric powder (TP) on carcass quality and blood profile in broilers fed lowprotein diets. Sixty broilers aged 14 days were divided to 5 treatment groups as follows: 1) Broilers fed19% protein diet without SALE plus TP as control (P0); 2) Broilers fed 17% protein diet supplementedto 4.5 g SALE/kg diet plus 0.5% TP (P1); 3) Broilers fed 17% protein diet supplemented to 4.5 gSALE/kg diet plus 1% TP (P2); 4) Broilers fed 15% protein diet supplemented to 4.5 g SALE/kg dietplus 0.5% TP (P3) and; 5) Broilers fed 15% protein diet supplemented to 4.5 g SALE/kg diet plus 1%TP (P4). Supplementation of SALE plus TP significantly affected body weight gain, feed intake, proteinintake, thigh meat haemorrhage and fat deposition (P 0.05). In conclusion suplementation of SALE plus TP had no beneficial effect onreducing fat deposition in broilers fed low protein diets, but it reduced blood uric acid but increasedblood glucose concentration.

The experiment was conducted at Poultry Research center University of Agriculture Faisalabad to evaluate the Arsilvon super, Bedgen40 and Hepa-Cure herbal medicines on broiler performance, immunity and hematology. For this study one hundred eighty day old broiler chicks were purchased from local hatchery and were reared in a group for one week. After one week, one hundred twenty broiler chicks of middle weight range were picked up randomly and divided into 12 experimental units (10 chicks/each).These units were allotted to 4 groups A, B, C, and D such that A group served as control without any supplementation, group B was supplemented with Arsilvon super @1ml/L, group C was supplemented with Bedgen40 @ 0.5ml/4L, and D was supplemented with Hepa-cure @ 1ml/L in drinking water. Supplementation of herbal medicine exhibited significant (P 0.05). Supplementation of herbal medicines showed significant treatment effect against the Newcastle disease but non-significant effect against the Infectious bursal disease. Herbal medicines revealed significant effects on blood glucose and red blood cells, but showed non-significant effect on cholesterol, hemoglobin, white blood cells and packed cell volume. In conclusion, herbal medicine supplementations in broiler revealed positive effect on performance, immunity and hematological parameters.

Effect of feeding Aspergillus awamori and canola seed on the growth performance and muscle fatty acid profile in broiler chicken.

The aim of this study was to examine effects of dietary supplementation with Aspergillus awamori and feeding canola seed on the growth and fatty acid profile in broilers. Twenty-eight chicks (15 days old) were assigned to the following groups: (1) control, fed a basal diet; (2) awamori, fed the basal diet supplemented with 0.05% A. awamori; (3) canola, fed a diet containing 5% canola seed; and (4) canola + awamori, fed the canola diet supplemented with A. awamori (seven birds/group). Body weight gain was increased by A. awamori but not influenced by canola seed. Breast muscle weight was increased in either awamori or canola groups. Although plasma triglyceride and cholesterol were decreased by feeding A. awamori or canola seed, fat content in the breast muscle were increased, accompanied by decrease in saturated fatty acids and increase in unsaturated fatty acids. Moreover, decreased thiobarbituric acid reactive substance and increased α-tocopherol content in the breast muscle was observed in all experimental groups. In conclusion, these results suggested that feeding canola seed and A. awamori might improve growth performance, and modified muscle fatty acid profile and α-tocopherol content, suggesting that they may improve meat quality.

Results: The significant (p<0.05) increase in hematological parameters like total erythrocyte counts, hemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular Hb and mean corpuscular Hb concentration in shatavari and vitamin E treated groups than control group. Whereas biochemical parameters like total serum protein, albumin, globin were significantly (p<0.05) higher and cholesterol, alanine aminotransferase and aspartate aminotransferase were significantly (p<0.05) lower in shatavari and vitamin E treated groups than control group. Conclusions: Supplementation of shatavari and vitamin E supplementation removes cold stress and improves immuno status of broilers.

Effect of Different Levels of Supplemental Yeast on Body Weight, Thyroid Hormone Metabolism and Lipid Profile of Broiler Chickens

In poultry, the benefits of probiotic supplementation on broiler performance and health have been reported. The present study examined the effect of supplemental yeast probiotic preparations on body weight, thyroid hormone metabolism and serum lipid profile in broilers. The experiment was carried out on hybrid Marshall broiler chickens (n=200). Two hundred 1-day-old chicks were randomly selected and distributed into 4 groups of 50 1-day-old chicks each (control, C; E10.5%, E21.5% and E32.0%, experimental groups). The birds were housed in an environmentally controlled poultry house with the floor covered with wood shavings. Chicks were fed commercial broiler starter diet for the first 28 days of age, followed by pelleted finisher diet from 29-42 days. Feed and water were provided ad libitum. Chickens fed 2.0% probiotic had a significantly (P<0.05) higher body weight when compared with the control group. The blood glucose concentration was significantly (P<0.05) different in the E31.5% probiotic supplemented group when compared with the control. There was highly significant (P<0.05) difference in T4 level in the E32.0% probiotic group when compared with the control. However, there was a significant difference in cholesterol concentrations observed in the experimental group supplemented with E10.5% probiotic. The concentration of triglycerides was not affected by the probiotic supplementation. Significant differences (P<0.01) were observed in HDL concentrations in all experimental groups supplemented with the probiotic when compared with the control group. In conclusion, supplementing broiler feeds with a yeast probiotic increased body weight, enhanced thyroid hormone metabolism, and decreased cholesterol and lipoproteins in broiler chickens.

Effect of feeding velvet beans (&lt;i&gt;Mucuna pruriens&lt;/i&gt;) on the lipid profile of broiler chickens

The effect of feeding velvet bean (Mucuna pruriens) meal on the lipid profile in broilers was investigated. Two hundred, 14 days old broiler chicks were randomly allocated to five dietary treatments in a completely randomized design and feeding continued for four weeks. Maize and soybean meal based control feed and four test diets prepared from the control feed by incorporating velvet beans at 10, 15, 20 and 25% levels served as five dietary treatments. Feed intake was unaffected by velvet beans. Serum total cholesterol level was lowered by 9.5, 9.7, 15 and 16% in birds fed with 10, 15, 20 and 25% velvet bean diets. Birds fed 25% VB diet showed an increase in HDL level by 8%. LDL level was lowered by 43.1, 36.5, 25 and 23.4%, respectively in birds fed with 25, 20, 15 and 10% velvet beans. Velvet beans reduced the serum triglyceride levels. Results suggest that Velvet beans contain a strong cholesterol lowering effect in broilers.

Comparative study of myocardial high energy phosphate substrate content in slow and fast growing chicken and in chickens with heart failure and ascites

In order to explain the biochemical mechanisms associated with deteriorating heart function in broiler chickens, this study compared myocardial high energy phosphate substrates in leghorns, feed restricted (Broilers-Res) broilers, ad libitum fed broilers (Broilers-AL), and in broilers that developed heart failure and ascites. The profile of adenine nucleotide content in the heart tissue did not differ between leghorns and Broilers-Res, but there were significant differences among Broilers-Res, Broilers-AL, and broilers with ascites. During intensive growth periods, leghorns and Broilers-Res showed increasing trends in heart ATP levels, whereas in fast growing broilers the heart ATP declined (p<0.021). ATP:ADP and ATP:CrP ratios increased with age in both leghorn and Broilers-Res, declined in fast growing broilers, and were the lowest in broilers that developed heart failure. The changes in heart high energy phosphate profile in broilers suggest that the energy demand of the heart during a rapid growth phase may exceed the bird's metabolic capacity to supply adequate levels of high energy phosphate substrate. The insufficiency of energy substrate likely contributes to the declining heart rate. In some individuals this may lead to impaired heart pump function, and in more severe cases may progress to heart pump failure.

Mineral elements are involved in health maintenance and have effects upon growth, their deficit in young animals leading to the reduction of growing rate. The objective of this paper work is to provide the effect of the supplementation with oligoelements of the intake structure upon the enzymatic profile in broilers.

Influence of Prebiotics Supplementation on Lipid Profile of Broilers

The prebiotic Mannanoligosaccharide (MOS) was extracted from yeast and copra meal and evaluated for their prebiotic potentiality on serum lipid profile and abdominal fat pad. The treatment groups were fed with basal diet (T ). The basal diet was supplemented with extracted MOS from yeast [@ 0.5 g/kg 1 (T ); 1 g/kg (T )] and from copra meal [@ 1 g/kg (T ); 1.5 g/kg (T )] and with MOS sources such as yeast [MOS 2 3 4 5 equivalent of 0.5 g/kg (T ); 1 g/kg (T )] and copra meal [MOS equivalent of 1 g/kg (T ); 1.5 g/kg (T )]. A broiler 6 7 8 9 trial was conducted for a period of five week. The results revealed that serum total cholesterol concentration was significantly (P<0.01) lowered by 10, 12 and 12 per cent in birds fed with T , T and T diet respectively 2 6 7 when compared with control diet in broiler chicken at 5 week of age. There was no significant difference in th serum HDL cholesterol of birds fed with extracted MOS / MOS equivalent source except T which was found 6 significantly (P<0.05) lower than control groups. LDL cholesterol level was similar in all treatment groups except higher value observed in T (91.69±13.54mg/dl). The abdominal fat pad (percentage of live weight) 5 was found to be significantly (P<0.01) lowest in T . This study indicates that the supplementation of prebiotic 3 extracted from yeast at 0.5 and 1g/kg and copra meal at 1.5g/kg and yeast source at 1g/kg level respectively reduced the abdominal fat content.
