Feeder Space

The effects on broiler performance of different floor, waterer, and feeder spaces and light treatments were estimated. Increased bird density resulted in a reduction in body weight, poorer feed conversion, reduced carcass quality and a reduction in monetary returns per bird started. Feeder space effects were inconsistent. Waterer spaces examined had little effect on bird performance. Light treatments studied revealed that cycles of 1 h of light with 3 h of darkness resulted in slightly superior feed conversion compared with cycles of 3 h of light and 1 h of darkness.

Two experiments were conducted to determine the effect of continuous and intermittent (1 hr on and 3 hr off) light treatments and the influence of strain, density and ration on performance of broilers maintained on each light treatment. Three thousand and six hundred broilers of two strains were grown with 0.093 m2 and 0.047 m2 of floor space per bird in experiment 1. Three thousand broilers from one strain were grown with 0.093 m2 of floor space per bird in experiment 2; 600 birds were fed each of five test rations. Body weight, mortality and feed efficiency were calculated in both experiments and slaughter grade was determined in experiment 1. Birds grown on intermittent light had lower mortality and better feed efficiency than those on continuous light. Average body weight at 7 weeks of age was not significantly different for the two light treatments; however, significant interactions were observed for strain × light, density × light and ration × light. Light treatments did not affect the percentage of grade A carcasses at slaughter. Strain and ration had a significant effect on 7-week body weight, as did bird density, in that birds maintained at 0.093 m2 were heavier and had a higher percentage of grade A carcasses than birds at 0.047 m2.

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.

The Many

The Chicken broiler is a type of superior race chicken that has high genetic properties, especially in growth. The use of herbs as medicines in medicine is now starting to increase, which is evident from the many traditional drugs manufacturers on the market. One of the herbs that can be used as an antibiotic for livestock is basil (Ocimum sp). Basil contains beta-carotene (provitamin A), which supports the function of vision, improves antibody function (influences immune function), protein synthesis to support growth process and as the antioxidant (Adnyana and Firmansyah, 2006). The purpose of this study was to determine the effect of the addition of basil leaves flour up to 12% level against broiler performance. The experiment was carried out experimentally using a completely randomized design (CRD). The results of statistical analysis showed that the addition of basil meal powder into the feed did not affect to feed consumption between levels (P> 0). The result of the statistical analysis showed that the addition of basil meal powder into the feed had no effect (P> 0,05) to the increase in body weight. The result of the statistical analysis showed that the treatment with the addition of basil powder into the feed had no effect (P> 0,05) to feed conversion. The result of this research can be concluded that the addition of basil powder into feed up to 12% level did not give significantly different effect on production performance such as feed consumption, body weight gain and feed conversion of the broiler.

Tibia Ash

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P < 0.0003) and feed consumption (P < 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P < 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P < 0.0024) and tibia ash (P < 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves.

Broiler Performance

This study was conducted to determine the effect of phytogenic feed additive and prebiotic on vegetable protein base diet in broiler performance.  A total of 90 chicks (Cobb-500) were weighted and randomly assigned to the three treatment groups (To, T1 and T2) and supplemented with either phytogenic feed additives or prebiotic and reared for 28 days. Data on live body weight, body weight gain, feed intake and feed conversion (FC) were taken at weekly interval. Results revealed that significant (P<0.05) increase in live body weight of broilers was evident in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group at 4th weeks of age. No significant (P>0.05) differences were found in live weight gain among the treatment groups on weekly intervals along the whole experimental period. However, significant differences (P<0.05) were evident on cumulative weight gain at 3rd and 4th weeks of age. In case of feed intake at the age of 3rd and 4th weeks, significant (P<0.05) differences were obtained with decreased feed intake in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group. In case of feed conversion (FC), there were significant (P<0.05) differences among the groups on 1st week and 4th week of age. Best FC was accounted for prebiotic supplemented group along the whole experimental period. The survivability rates were 96.67%, 100% and 100% in control group, phytogenic feed additive and prebiotic supplemented group respectively. Results finally showed that vegetable protein when supplemented with phytogenic prebiotic feed additives and prebiotic c an additive beneficial effect on performance of when compared to non-supplemented control diet. So, ration using vegetable protein mixed with phytogenic feed additives or prebiotic can be recommended for broiler.Progressive Agriculture 28 (4): 323-330, 2017

Nail Removal

Broiler-type turkey poults were placed sex-separate in floor pens (60 birds/pen; ca. 5.5/m2) of an environment-controlled house. All birds received corn-soybean meal based rations paralleling commercial practice. Treatments were imposed at 5 wk of age and involved either debeaking alone (controls) or its combination with toenail-clipping (6 pens/sex/treatment). Body weight of nail-clipped turkeys was less at 6 and 10 wk than found with controls; however, the converse was observed by slaughter at 14 wk. Conversion of feed consumed during the 6 to 10- and 10 to 14-wk intervals was more efficient with nail-clipped than control birds. Mortality was similar between both groups from starting through to the finishing period whereupon noticeably fewer deaths occurred with nail-clipped as opposed to control turkeys. Dressed carcass yield was greater when nail removal was performed than not. A 40% reduced incidence of utility grades indirectly suggested that this yield advantage was due to less "on the line" trimming during processing. Conformation, fleshing and finish grades were unaltered. Both sexes responded comparably. All advantages arising as a consequence of toenail-clipping could be explained in terms of reduced flock activity.

SummaryThe trial was conducted to evaluate the effect of a by-product of solid state fermentation (Synergen™ (SGN), Alltech Inc, Nicholasville KY, USA) on broiler performance and health. One thousand two hundred and eighty male Ross 308 broilers were used in a 42 day pen trial. The trial was designed as a 2 × 2 factorial, with two diet specifications (standard and reformulated) plus or minus SGN (0 and 200 g/t, SGN replaced with commercial enzyme Ronozyme™ at 150 g/t) to give four dietary treatments in total in a corn-soy based diet formulated to commercial standards. Birds fed the reduced energy diets had significantly lower cumulative feed intakes at 42 d (P < 0.01) compared to those on the full specification standard diet. There were no significant differences in broiler body weight due to treatments at any age. Significant improvements (P < 0.05) in FCR, primarily due to SGN inclusion in the feed, were observed for all weekly reported data. There were no significant differences in either mortality or EPEF for any of the treatment diets. The present study indicates that SGN, a by-product of solid state fermentation (SSF) can improve feed conversion of broilers fed a corn-soy diet.

<p>The authors have investigated the effect of different levels guanidinoacetic acid in the diets of quails on their productivity and carcass quality. Experimental studies were carried out in the conditions of the problematic research laboratory of feed additives in the National University of Life and Environmental Sciences of Ukraine. Material for scientific and economic experience was quail of Pharaoh species of meat direction of productivity. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form. Young animals were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations. The effect of using different levels of Guanidinoacetic Acid (GAA) in compound feed on productivity and carcass quality of young quails was studied. We have found that compound feed with the level of GАА 0.06% contributes to live body weight increase by 3.9 g and muscles of the pelvic limbs yield by 26.2%. At the same time, use of diets with a level of 0.12% of guanidine acetate increases live weight by 13.5 g, the absolute growth of 6.5 g, average daily growth by 0.9 g, a relative growth of 2%, the mass of carcass, semi-eviscerated carcass, and eviscerated carcass of 4.8, 4.9 and 4.3% correspondingly, slightly increases the mass of pectoral muscles by 9.1%, significantly increases the yield of muscles of the pelvic limbs by 36.4%, and reduces feed conversion by 5%. Poultry which was fed with 0.18% of GАА exceeded control of body weight by 12.2 g, the absolute growth by 4.4 g, average daily growth by 0.6 g, the relative growth by 1.1%, yield of muscles of the pelvic limbs by 36.4% and  had a lower feed conversion rate by 9.1%. During the study period the safety of livestock which was fed with GААvwas high and ranged from 90 to 96%.  It was established the perspective of further research, which is to examine the impact of Guanidinoacetic Acid on the egg production of egg-laying quails, morphological and chemical composition of eggs and  their hatching  quality.</p>

Abstrak: Penelitian initelah dilakukan di Laboratorium Lapangan Peternakan Fakultas Pertanian Universitas Syiah Kuala yang berlokasi di Darussalam Banda Aceh sejaktanggal 4 Desember 2015 sampai dengan tanggal 9 Januari 2016. Tujuan penelitian adalah untuk mengetahui pengaruh subtitusi Amtabisterhadap performa ayam broiler yang meliputi pertambahan berat badan, konsumsi pakan dan feed conversion ratio. Parameter yang diamati meliputi konsumsi ransum, pertambahan berat badan, konversi ransum dan efisiensi ransum. Hasil penelitian menunjukkan bahwa substitusi Amtabis dalam ransum komersial pada level yang berbeda selama perlakuan berpengaruh nyata (P0,05) terhadap pertambahan berat badan, namun tidak menunjukkan perbedaan yang nyata (P0,05) terhadap konsumsi pakan, rasio konversi pakan dan efisiensi pakan.Terjadinya penurunan performa broiler dengan pemberian Amtabis kemungkinan disebabkan karena ketidak seimbangan kandungan nutrisi dalam ransum akibat penambahan Amtabis dalam pakan komersil. The Effect of Substitution Fermented Amtabis with Aspergillus Niger on Broiler Performance Abstrack: Study on the effect of substitution fermented Amtabis with Aspergillus niger on broiler performance was conducted at Experimental Farm Laboratory, Animal Husbandry Department, Syiah Kuala University Darussalam Banda Aceh from 4 December 2015 to 9 January 2016. The purposes of this study was to evaluate substitution of fermented Amtabis with commercial broiler on broiler performance including body weight, feed consumption and feed conversion ratio. Parameters which were observed in this study were body weight, feed consumption and feed conversion ratio. The results on the study indicate that substitution of Amtabis in commercial feed significantly effected (P0,05)on body weight, but had no significantly effect (P0,05)on feed consumption, feed conversion ratio and feed efficiency.Decreasing of performance broiler by substitution Amtabis in the commercial feed was probably caused by imbalance of nutritive feed formulation after Amtabis substitution
