This research study was conducted to determine the effects of dietary supplementation of kudzu leaf meal (KLM) and alfalfa meal (AM) on broiler performance, carcass characteristics, and organ parameters. Kudzu leaf meal and AM were added at rates of 6% and 7.3%, respectively, to a complete broiler starter diet. Three treatments (control (complete broiler starter diet), KLM supplementation; and AM supplementation) with four replicates were fed to 217 male broilers over a 21 d battery cage grow out. Data were analyzed as a completely randomized design with battery cage representing the experimental unit. Birds on KLM and AM had a lower average body weight, lower cumulative feed consumption, and a higher adjusted feed conversion than control (p < 0.05). Additionally, there were observed treatment effects on whole breast weight (p = 0.0010), with control being higher than both treated diets. Minimal treatment effects were observed for organ parameters. Furthermore, there were no observed treatment differences for mortality (p > 0.05). Although broilers on KLM did not perform as well as those in the control group, these results are indicative that kudzu is safe to use in poultry production and has a high potential as a protein supplement in tropical regions with a low availability of commercial protein feedstuffs.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

ABSTRACT: To evaluate inclusion levels and residual effects of diets containing yeast extract (YE) plus blood plasma (BP) on the performance of 36 to 60-days old piglets, 105 piglets were used (8.75±0.72kg), and they were distributed under a randomized block experimental design with five treatments (control - 2.0% BP; 1.0% BP plus 0.0, 1.0, 2.0, or 3.0% YE), seven repetitions, and three animals per experimental unit. Piglets were given experimental diets from 36 to 49 days of age. From 50 to 60 day of age, all piglets received the same diet. No effects from treatments (P>0.10) were observed on the performance variables from 36 to 49 day of age. From 50 to 60 day of age, an effect was observed from YE levels on the daily feed consumption (P<0.03), daily weight gain (p<0.01), and final weight (P<0.06), which increased quadratically up to 1.67, 1.67, and 1.55% YE levels, respectively. Piglets which were fed with the diet containing 1.0% BP + 2.0% YE were observed to have better feed conversion ratios (P<0.01) as compared to the control diet (2.0% BP). As it provides a better residual effect, the inclusion of 1.67% yeast extract may replace 50% of blood plasma in 36 to 49-days old piglet diets.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase.   Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.

ABSTRACT-QMFS2019Poultry production provides source of protein and contributes an important income for Vietnamese farmers. Among the poultry in Vietnam, ducks account for 27.3% of head of poultry and even 55.7% in Mekong Delta region. Along with the development of rearing ducks, bacterial, viral and fungal diseases occurring in the two last decades induced bad effect for poultry producer. Escherichia coli, Salmonella enterica, Streptococcal or Pasteurella act as major pathogenic bacteria in duck. The aims of this study were to investigate the antibacterial activity of garlic Allium sativum against E. coli, Staphylococcus aureus, Salmonella Typhimurium and to evaluate the effect of garlic on growth performance of duck from 1-28 old-days. The results indicated that fresh garlic and dried garlic powder showed inhibitory effect against pathogenic tested strains from 2% and 4% w/v, respectively. The inhibition zones and the minimal inhibitory concentration (MIC) values of garlic extract ranged from 11.3-28.3 mm and 0.02-0.2 g/ml, respectively. After 28 days of diet with garlic supplemented, D3 (2% of fresh garlic in water) showed significantly different in weight gain (WG), feed conversion ratio (FCR), protein efficiency ratio (PER), average daily weight (ADW); whereas, D2 (2% of garlic powder in basal diet) only possessed a difference significant in feed consumption (FC) compared to the D1 (control without garlic supplementation). The obtained results demonstrated the potential of garlic application in poultry production.

Growth performance and carcass characteristics of capons (castrated cockerels) from three breeds/strains locally presented in Slovenia and Austria were investigated. Growth and feed consumption data were collected for a 156-d and 199-d period, when randomly chosen animals were slaughtered and their carcasses dissected. The feed conversion rate in barred Prelux, Sulmtaler and Styrian capons for the whole growing period was 6.24 kg, 6.32 kg and 7.53 kg, respectively. Average body weight in barred Prelux and Styrian capons increased only in the first 156 days of age, but not further on. Cumulative mortality rate in Sulmtaler capons was 19.05 % and was 2.7- to 4.4-fold higher as compared with Styrian and barred Prelux capons (6.90 % and 4.31 % respectively). Sulmtaler capons had the lowest abdominal fat content. Barred Prelux capons, as compared to capons from other two breeds were characterized by higher pre-slaughter weight, higher carcass weight and higher dressing out percentages. This indicates that the layer type barred Prelux cockerels have a potential to be as capons put to profitable use.

The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

Monensin is an ionophore antibiotic, the inclusion of which in the feed of beef cattle favors the best use of feed nutrients, via ruminal modulation. However, there are concerns regarding the residence of residues in the carcass from metabolism of monensin. The objective of this study was to evaluate the productive performance, carcass characteristics, serum parameters, tissue residual depletion and economic benefit of finishing of young bulls in confinement with monensin in the ration. Thirty-six animals were confined, and given 50% corn silage feed and 50% more concentrated feed. The experimental design was completely randomized, with two treatments (with or without monensin) and 10 replicates for the control group and eight for the monensin group. The use of monensin reduced the dry matter intake in relation to live weight (2.36% vs 2.55%), and improved feed conversion (8.61 vs 10.06 kg kg?1); the animals presented higher live weight (511 vs 494 kg), higher warm carcass weight (285 vs 272 kg) and an increase in fat thickness (4.97 vs 4.25 mm) compared to control animals. These increases in performance gave higher economic results, with a profit margin of R$ 122.84 per animal. A waiting period of 16 h before slaughter resulted in monensin concentrations below 0.25 µg kg?1 in edible organs and tissues, values well below those permitted by legislation. The use of monensin for young bulls in confinement promoted improvements in productive and economic performance, without leaving residues in edible tissues.

AbstractA total of 608 Ross 308 broiler chickens of both sexes were studied to determine the effect of Lactococcus lactis 847 bacteria compared to probiotic bacteria Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 on body weight, feed consumption and conversion, mortality, dressing percentage, postmortem carcass traits, composition of breast muscle tissue, and blood plasma traits. Feeding diets with bacteria to chickens did not increase body weight at 42 days of age or improve feed conversion compared to control chickens. It significantly reduced chicken mortality compared to the control group, from 3.3% to 1.4% (P<0.01). No significant differences were found in feed consumption and conversion. There were no significant differences in the weight of carcasses and their parts. Lactococcus lactis 847 and Lactobacillus plantarum 837 bacteria significantly increased dressing percentage (P<0.05). Lactococcus lactis 847 significantly increased liver weight (P<0.05). No significant differences were observed in carcass fatness, and in the dry matter, protein and fat content of breast muscles. Feeding diet with Lactobacillus plantarum 837 to chickens significantly decreased plasma triglyceride levels, and feeding diet with Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 significantly decreased the level of high-density cholesterol (P<0.05). In conclusion, Lactococcus lactis 847 bacteria in diet significantly reduce losses due to digestive disorders while having no effect on the quantity and proportion of saleable cuts in the carcass, the composition of breast muscles and basic blood parameters.

An experiment was conduted to evaluate the effectiveness level of corn substituted by Morinda citrifolia leaf meal in broiler ration. The use of Morinda citrifolia leaf meal substituted for corn in ration is expected to improve feed conversion in broiler chickens and produce chicken meat that safe for consumption and free of chemical antibiotics residues . Completely Randomized Design (CRD) was used to analyze data obtained from this research. One hundred and sixty chicleas (7 days aged) divided into 5 (five) treatments with 4 (four) replications and each replication consisted of 8 (eight) chicleas. Ration of treatments were a negative control diet (R0), 1% Morinda citrifolia leaf meal (R1), 2% Morinda citrifolia leaf meal (R2), 3% Morinda citrifolia leaf meal (R3) and commersial ration (R4). All treatments rations were added a natural feed additive that consist of 0,125% Curcuma and.0,075% Turmeric meal. Measured parameters were feed intake, weight gain, feed conversion ratio, mortality, percentages of carcas and abdominal fat. Results showed that feed consumption, weight gain, and feed conversion ratio were significantly (p <0.05) influenced by treatments. Mortality, percentage of carcas and abdominal fat were not significantly (p >0.05) influenced by ration treatments. Mortality rates in chickens using a ration of treatment was 0%, while using the control diet 0,78% (1 bird). The counclusion showed that the substitution of 1-2% Morinda citrifolia leaf meal in ration has better performance compared to the control diet, with improvement of feed conversion ratio was 7.57 and 9.2% respectively was more efficient than the control diets

A total of (120) day old Bounty Fresh colored broiler chickens were carried out in a completely randomized design to evaluate the effect of different levels of oregano leaf meal (OLM) on the growth performance at a dietary levels of 0, 3 ,6 and 9% respectively.   Results showed significant in terms of cumulative feed consumption, gain weight and feed conversion ratio. Broilers given 6% of level of oregano (T3) had the heaviest body weight on the seven week of age with a mean 1955.25 grams while the lightest was those broilers without the supplementation of oregano leaf meal (T1) with a mean of 1743.75 grams. The inclusion of OLM as fed diet were the most efficient feed converter and therefore, has the potential to increase rapid growth and improve vitality and livability of colored broiler chicken. Insignificant result was obtained in terms of the percentage rate of growth, dressing percentage with and without giblets and feed conversion ratio as revealed by the analysis of variance. However, in terms of the income over feed and chick costs, Colored broiler chicken fed with 6% oregano leaf meal had the highest return of Php 88.89 and the lowest return was those broilers without oregano with a return of Php 50.47.The results suggest that OLM at 6% level can be safely used as feed ingredients to the broilers without any deleterious effect.
