Feed Conversion Rate

The basic feed supplemented with Sargassum powder (1%, 2%, 3% and 4%) provided more amount of essential amino acids, long chain fatty acids and minerals necessary for the growth of poultry than the basic feed. The growth promoting ability of Sargassum increased from 1% to 2% and then there was ste ady state, which is reflected in the weight gain, feed intake, feed conversion rate, carcass qualities and serum parameters of poultry. Sargassum powder had increased the growth to gain about 1265g more weight compared to the control and the supplementing effect was the maximum at 2% Sargassum powder. The feed intake per bird increased from 4647g at 1% Sargassum powder to 4813g at 4% Sargassum powder while it was 3042g in the control group. The feed conversion rate increased from 51.5 to 51.8 instead of 33. 9% in the control. Sargassum treatment increased the liver weight from 2.26% to 2.30%, the heart weight from 0.53% - 0,45%, the gizzard from 1.76% to 1.83%, the intestinal weight from 210.2 to 226.18%, the leg proportion from 3.77% to 4.57%, the breast weigh t from 28.26% to 30.27%, the thigh weight from 13.37% to 14.68%, the drumstick from 14.16% to 15.28% and the dressing from 70.32% to 81.12%. The maximum supplementary effect was noted at 1% and 2% of the Sargassum powder. Dietary treatment of broiler chick s with Sargassum powder significantly (P<0.05) decreased plasma cholesterol and globulin while increased the total serum protein, albumin, calcium, phosphorus and triglyceride compared to control. The 1% Sargassum gave 1.8 fold profits while 2%, 3% and 4% Sargassum powder gave 1.95 fold profit compared to the control. Meat qualities of chicks fed with 1% and 2% Sargassum were superior to the meat of poultry fed only with the basic feed.

Abstract The effect of garlic extract on body weight, feed intake, feed conversion rate, mortality rate, dressing percentage, carcass traits, chemical composition of breast muscles and blood plasma parameters was investigated in a feeding trial with 640 Ross 308 broiler chickens of both sexes. The experiment was characterised by a two-factor design, with liquid garlic extract (GFA ) and sex as factors. In comparison with the unsupplemented control group, supplementing diets with 1.00 (GFA 1), 1.50 (GFA 2), and 2.25 (GFA 3) ml kg-1 for 42 days increased body weight, with a significant difference for the GFA3 group (P≤0.01). Bird mortality was 2.78% in the control group and 0.10%, 0.63%, and 0.60% in the GFA1, GFA2, and GFA3 supplemented groups, respectively (P≤0.01). Feed intake (kg/42 days) was 4.50 per broiler in the control group and 4.51, 4.68, and 4.85 kg-1 per broiler in the experimental groups (P≥0.05), respectively. Feed conversion rate was 1.80 in the control group and 1.77, 1.76, and 1.80 kg/kg in the GFA1, GFA2, and GFA3 groups, respectively (P≥0.05). GFA increased European Production Efficacy Factor (EPEF) from 331 in the control group to 347, 363, and 356 points in the experimental groups, respectively (P≤0.01). Dressing percentage in the GFA3 group was significantly higher than in the control group (74.8% vs 72.5%; P≤0.01). GFA at the concentration of 2.25 ml kg-1 significantly increased the weight of breast muscles. Supplementing the diet with GFA at the level of 1.50 ml kg-1 caused a significant increase in liver weight (P≤0.01). Feeding with GFA at a rate of 1.5 ml kg-1 caused a significant increase in the protein and crude ash content of breast meat compared to the control group (P≤0.05). The highest dose of GFA significantly increased total protein content of serum compared to the control group (P≤0.01). No significant interaction of GFA by sex on the analysed parameters was found. It is concluded that GFA at 2.25 ml kg-1 caused a significant improvement in the body weight of broilers and their carcass parameters, while a significant reduction in bird mortality for the GFAsupplemented groups was observed during the rearing period. It appears that the optimum level of GFA , when the crude protein concentration in the commercial starter and grower diets ranges between 210 and 220 g kg-1 is 1.5-2.25 ml kg-1 of the starter and grower diets.

Abstract Background The development and utilization of probiotics had many environmental benefits for replacing antibiotics in animal production. Bacteria in the intestinal mucosa have better adhesion to the host intestinal epithelial cells compared to bacteria in the intestinal contents. In this study, lactic acid bacteria were isolated from the intestinal mucosa of broiler chickens and investigated as the substitution to antibiotic in broiler production. Results In addition to acid resistance, high temperature resistance, antimicrobial sensitivity tests, and intestinal epithelial cell adhesion, Enterococcus faecium PNC01 (E. faecium PNC01) was showed to be non-cytotoxic to epithelial cells. Draft genome sequence of E. faecium PNC01 predicted that it synthesized bacteriocin to perform probiotic functions and bacteriocin activity assay showed it inhibited Salmonella typhimurium from invading intestinal epithelial cells. Diet supplemented with E. faecium PNC01 increased the ileal villus height and crypt depth in broiler chickens, reduced the relative length of the cecum at day 21, and reduced the relative length of jejunum and ileum at day 42. Diet supplemented with E. faecium PNC01 increased the relative abundance of Firmicutes and Lactobacillus, decreased the relative abundance of Bacteroides in the cecal microbiota. Conclusion E. faecium PNC01 replaced antibiotics to reduce the feed conversion rate. Furthermore, E. faecium PNC01 improved intestinal morphology and altered the composition of microbiota in the cecum to reduce feed conversion rate. Thus, it can be used as an alternative for antibiotics in broiler production to avoid the adverse impact of antibiotics by altering the gut microbiota. Graphic Abstract

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

Ad Libitum

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

Aquaculture has become a primary method to produce various aquatic products, and intensive aquaculture technologies have become commercially important. To improve the efficiency of intensive aquaculture per unit area without reducing the growth rate of cultured fish, the present study explored the potential of artificial substrata in ponds. Our results showed that the concentrations of total nitrogen (TN) and total phosphorous (TP) in the ponds with different stocking densities of grass carp were lower than those in the control group in most cases. Further, the feed conversion rate of grass carp was significantly reduced by introducing these artificial substrata, and the culture density could be significantly increased without reducing the growth rates of these fish. Artificial substrata also significantly enriched specific bacteria and changed the structure of the microbiota in pond water. The relative abundance of Proteobacteria was significantly increased, and bacteria closely related to N and P cycles, such as Hyphomicrobium, Chitinimonas, Legionella, Shewanella, Roseiflexus, and Planktothrix were significantly enhanced. These results showed that the artificial substratum could increase TN and TP removal in aquaculture pond water by enriching N and P cycle-related bacteria, thus significantly increasing the specific growth rate of grass carp and significantly reducing their feed conversion rate. Finally, the stocking density of grass carp and the yield per unit area of pond could be increased without reducing the growth rate.

The objective of this study was to evaluate the effects of feed supplementation with two prebiotic herbs—Origanum vulgare and Zingiber officinale—on growth performance of broiler chickens. The feed conversion ratio was determined weekly by dividing feed intake by body weight gain. A total of 400 one-day-old broiler chicks were divided into four treatment groups of four replicates of 25 chickens each using a complete design random. The four treatment groups were T0 (control), T1 (0.5% oregano), T2 (0.5% ginger), T3 (0.25% oregano + 0.25% ginger). The chicks were grown to 42 days of age. Weight gain, feed intake, conversion, carcass quality and mortality were determined weekly. Data analysis revealed that during the first 35 days of broiler chicken’s life, none of the dietary interventions had any effect on productive parameters (P > 0.05). However, during the last week of treatment, the oregano and ginger supplementation had a positive effect on weight gain and feed conversion (P < 0.05) than in the control group. In conclusion, the addition of oregano and ginger in the daily food ratio for broiler chickens during the last stage of the productive cycle improved the productive parameters, and carcass characteristics.

The study was performed with the objective of verifying raw soy feed, oxidized oil feed, and a control group. Performance evaluation was done at 7, 14, and 21 days of age. Metabolism assay was carried out between the 17th and 20th days for nutrient digestibility analysis. On the 21st day, two birds per repetition were sent for necropsy and collection of intestine fragments (duodenum and jejunum) for histomorphometric analysis. Eight to 14 days after treatment with Salmonella, individuals showed lower feed intake and feed conversion than the control group. Treatment with coccidiosis decreased all performance parameters in the control. Raw soybeans and oxidized oil induce lower weight gain and higher feed conversion compared to the control feed. Unlike after 14 days, at 21 days treatment with salmonella a decrease in weight gain was noted. For the group challenged by coccidiosis feed intake, the feed conversion remained lower than the control group. Undesirable effects on performance in the groups fed raw soybean and oxidized oil remained at up to 21 days. In the evaluation of digestibility, it was observed that raw soy had lower values for digestibility of dry matter, ether extract, and nitrogen balance due to intake. In addition, a lower ratio of villus:crypt measurements was observed. Lower villus height was found in the duodenum of the group challenged by coccidiosis. This group presented a positive correlation between the digestibility of ether extract and the duodenum, indicating that increased villus height implies an increased digestibility of ether extract. The results obtained for the jejunum showed a positive correlation with villus height in groups challenged by coccidiosis, raw soybeans, and oxidized oil; and to crypt depth in the group challenged with oxidized oil. The information obtained in the present study demonstrates that nutrient digestibility parameters can be useful tools for the analysis of the intestinal health of broiler chickens.

The present study was conducted to investigate the effects of using probiotic <em>Yeasture</em>® at different rearing periods on performance, intestinal microbial population and carcass traits in broiler chickens. A total of 378 one day old chickens (male and female) were randomly allotted to one of the 21 floor pens in a completely randomized design with seven treatments and three replicate groups and eighteen chickens in each group (9 male and 9 female). The Experiment treatments consisted of seven groups: A (control, without probiotic), B (prebiotics feeding between 1 to 10 days), C (prebiotics feeding between 1 to 24 days), D (prebiotics feeding between 1 to 42 days), E (prebiotics feeding between 11 to 24 days), F (prebiotics feeding between 11 to 42 days) and G (prebiotics feeding between 24 to 42 days). The chickens received the desired probiotic at different days of rearing period. The basal diets were corn and soybean meal, so 0.3 g/kg of basal diets in starter (1-10 days), 0.25 g/kg of basal diets in grower (11-24 d) and 0.2 g/kg of basal diets in finisher (24-42 d) period of probiotic was added to the basal diets for each other than treatment. The growth performance (evaluated through body weight gain, feed intake and feed conversion ratio), intestinal microbial population (the measurement of <em>Lactobacillus</em> and <em>Coliforms</em>) and carcass traits (relative weights of carcass, intestine, liver, gizzard and abdominal fat) were determined. Body weight gains and feed conversion ratio were significantly improved in broilers with added probiotic compared to the control group (P&lt;0.05) whereas feed intake was not significantly altered. In addition, intestinal microbial population and carcass and gizzard weights markedly increased in the probiotic treated birds compared to control chickens (P&lt;0.05). These results show that diet supplementation with probiotic <em>Yeasture</em>® at the early days of the rearing periods of broiler chickens especially, 1 to 24 and 1 to 42 days, had a positive effect on intestinal microbial population, leading to more nutrients being assimilated by the chickens and consequently greater performance in broiler chickens.

Abstract This study looked at the effects of processed kola nut husks meal (PKHM) utilization as a feed ingredient on broiler chicken in a 42-day feeding trial. Kola nut pod husks were processed into a PKHM using ash treatment and rumen liquor fermentation. Three experimental diets were developed at both the starter and finisher phases, with PKHM included at 0, 4, and 8%, and dubbed diets 1, 2, and 3, respectively. In a fully randomised design, 240 Arbor Acres broiler chicks were randomly assigned to three treatments (10 birds per replicate). Except for the significantly improved (P<0.05) feed conversion ratio of broiler chickens fed diets 2 and 3 at the grower phase (22-42 days) and overall (0-42 days), the performance indices were not significantly (P>0.05) affected by PKHM dietary inclusion. Broiler chicken carcass characteristics and relative internal organ weights remained constant (P>0.05) through diets. The serum glutathione concentration in broiler chickens fed an 8 percent PKHM inclusive diet increased significantly (P<0.05) than those on the control diet and 4 percent PKHM inclusive diet. When broiler chickens fed an 8 percent PKHM inclusive diet were compared to those fed a control diet, the serum catalase concentration was significantly higher (P<0.05). The total serum protein, creatinine, alanine aminotransferase, aspartate transferase, and cholesterol levels remained constant (P>0.05) regardless of dietary treatment. Dietary PKHM inclusion of up to 8% enhanced improved feed efficiency and increased antioxidant enzyme concentration and did not affect the serum biochemical indices concentration.Statement of NoveltyKola nut husk is one of the agro-wastes that contributes to environmental deterioration due to its underutilization. The kola nut husk is underutilised in broiler production due to its chemical constitution, minimal nutritional value, and poor digestion. In this research, kola nut husk meal was ash treated and rumen liquor fermented before being integrated at varying levels in the experimental diets and the performance characteristics, antioxidant status, serum protein, enzymes and biochemical were evaluated. The findings of this study could aid in the development of an agro-waste-based, low-cost functional feed for broiler chicks that incorporates the underutilised kola nut husk and other abundant agrowastes as macro-ingredients.
