DIGONESTIC   ENVIRONMENTAL MONITERING SYSTEM IN A POULTRY HOUSE

This experiment was conducted at a closed poultry house , Poultry Research Station , office of Agricultural Research, Ministry of Agriculture, Baghdad, Iraq, for the period from 2/9 to 14/03/2016 for total rearing of 35 days. To diagnose and monitoring the Environmental factors such as temperature, humidity , density, and the carbon dioxide levels inside the house during winter season, and its impact on the productive performance of broiler chickens Rose 308 breed .The dimensions of the house was ,length 35 m x width 7.5 m x Height 2.5 m, by total space volume 3656.25 m3. The ventilation system in the house was (negative pressure type). The house is totally closed, small fans for (minimum ventilation) in the winter are functioned, and large fans for ventilation in the evaporative cooling operation were used in the summer. 1000 sexed birds were used in this experiment imported through commercial hatchery in Abu Ghraib. The house was divided into three thermal Zones in order to find out whether heterogeneity in environmental conditions is existed in the house and at bird level .as a result the impact on the homogeneity in the weights of marketed birds . The treatments have been distributed into 32 rearing cages by the following order: 8 cages with the density of 50 birds / cage, the remaining 24 cages were divided into the density of 25 birds / cage. The results showed that there were significant differences between the treatments in the rate of body weight ,body weight gain, feed intake and feed conversion efficiency among densities and the three thermal zones due to the presence of cool air leaks into the house at the front ,End of the house, and its sides especially when fans are on , along with dead Air pockets that were identified in many places in the middle of the housed, yet this Zone was the one that had the best productive traits in comparison with the other two zones. The purpose of this experiment is to study environmental parameters homogeneity inside the shed in addition to impact of CO2 levels and impact of birds density on productive traits.

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,99±0,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%. (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.99±0.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.

The Impact

This study was planned to evaluate the impact of different nano-curcumin levels on the growth rate, carcass, blood chemistry and caecal microbes of growing quail. A total of 270 Japanese quails at one-week-old were distributed to six equal groups; each group consisted of 45 unsexed birds with five replications (nine quails each). The 1st group was fed a basal diet, whereas the 2nd, 3rd, 4th, 5th and 6th groups were fed diets containing nano-curcumin (0.1, 0.2, 0.3, 0.4 and 0.5 g/kg diet, respectively). Nano-curcumin levels significantly increased (p ≤ 0.0001) body weight at 3 weeks and 5 weeks of age. Body weight gain during 1–3, 3–5 and 1–5 weeks of age was significantly increased (p < 0.0001) in groups treated with nano-curcumin levels (except at 0.3 g/kg; 1–3 weeks) compared to control. During 1 to 5 weeks, feed intake was decreased (p < 0.0001) in birds receiving nano-curcumin (0.1, 0.3 and 0.4 g/kg) diets. The best values of feed conversion ratio were recorded for the 0.4 g nano-curcumin-treated group. Carcass traits were not affected Nano-curcumin levels. The inclusion of nano-curcumin (0.2, 0.3 or 0.5 g/kg) significantly increased serum TP (p = 0.0004), albumin (p = 0.0078) and globulin (p < 0.0001). Quails fed with nano-curcumin (0.2 g/kg) exhibited the highest SOD and GSH activities, serum IgG and IgM concentrations and complement values compared to control. The addition of any level of nano-curcumin in the quail diet also significantly improved the lipid profile. In conclusion, supplemental nano-curcumin had beneficial impacts on growth, lipid profile, blood constituents, antioxidant indices, and immunity of growing quail, as well as increasing counts of lactic acid bacteria and reducing pathogenic bacteria.

An experiment was conducted on weaned piglets at Piggery Research Unit of Regional Agricultural Research Station (RARS), Tarahara, Sunsari from 12 September to 4 December 2019 for 84 days after adjustment period of seven days. Twenty piglets after weaning of 4-6 months age were allocated into four treatments each with 5 replications by using Completely Randomized Design. Four type of experimental diets were composed for experimental piglets. Piglets of T1 (control) group were provided adlib concentrate mixture, 95% concentrate feed + 5% water hyacinth (WH) were given to T2 group, 90% concentrate feed + 10 WH were offered to T3 group and piglets of T4 group were fed 85% concentrate feed + 15% WH as per their daily requirement. Feed and water hyacinth intake were recorded daily and body weight gain was measured once a week. Experiment revealed that feed and WH intake was highly significant (p<0.001) among treatment groups. Highest total body weight gain was obtained in control group (T1) (37.66 kg) followed by T3 (34.91 kg) and T2 (34.25 kg) which was non-significant among diet groups. Similarly, highest average daily gain was observed higher for T1 (control) group (448 g /day) followed by T3 and T2 group (415.59 and 407.73 g/day, respectively). Feed Conversion Ratio (FCR) was observed almost similar in all treatment groups (1:2 kg). Experiment suggested that concentrate mixture can be safely replaced with WH up to 15% without any adverse effect on body weight gain.

This study was conducted to investigate the effect of adding Lycium barbarum extract to drinking water on some productive traits of Japanese quail. A total of 270 one-week-old Japanese quails were used in this study. The birds were divided into six treatments (45 for each). Each litre of drinking water (RO) was treated with 400 mg of L. barbarum extract add from (leaves, fruits, stems, and roots) for T2, T3, T4, and T5 respectively. 400 mg of mixed extract from leaves, stems, fruits and roots of L. barbarum were added to drinking water (T6). The control treatment (T1) was free of L. barbarum drinking water. The results showed no significant differences in the body weight, body weight gain, feed consumption and feed conversion ratio. A significant decrease in the age of sexual puberty and sexual maturity for males and females were recorded in the second and third treatments compared to the other treatments. On the other hand, the results showed no significant differences between the experimental treatments for the weight at sexual puberty and maturity for males and females. It can be concluded that the leaves and fruits of L. barbarum extract decreased the sexual puberty age for males and females of Japanese quail. On the other hand, it has no effect on body weight, body weight gain, feed consumption and feed conversion ratios.

Abstract. The objective of this study was to evaluate the impact of a low metabolizable energy (low-ME) diet supplemented with a multienzyme blend (KEMZYME®) on the growth performance, carcass traits and meat quality of chickens. A total of 108 broiler chicks (Ross 308) were randomly allocated to three experimental groups with six replicates per treatment and five birds per replicate; the groups were treated as follows: a control diet with no additive and standard metabolizable energy (ME; 3200 kcal kg−1); a low metabolizable energy (low-ME; 3000 kcal kg−1) diet; and a low-ME diet + 0.5 g kg−1 diet of enzyme (low-ME–Enz). Live body weight (LBW) at 43 and 47 d and body weight gain (BWG) during the periods from 38 to 43, 43 to 47 and 33 to 47 d decreased with the low-ME and low-ME–Enz diets in comparison with the control-diet (p<0.05). The values of the feed conversion ratio (FCR) were significantly increased with low-ME diets with or without enzyme at all growing stages. There were no significant differences among treatments in terms of carcass traits. With the exception of the jejunum weight, dietary treatments did not affect any digestive tract segments. Meat hardness decreased with the low-ME–Enz diet compared with the other diets (P=0.039). Meat yellowness of the breast muscle increased (P=0.001) with the low-ME–Enz diet in comparison with the other treatments at 24 h post-slaughter. In conclusion, the low-ME diet supplemented with KEMZYME® did not influence most of performance parameters and carcass traits of chickens; however, adding enzymes to the low-ME diet is an effective strategy to improve the meat quality criteria and small intestine characteristics.

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 aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

Ross 308 broiler chicks (n = 240) aged 1 day were assigned to five groups for eight replicates (six chicks for each) (3♂ and 3♀). Basal dietary groups were supplemented by 2000, 4000, and 6000 mg/kg cinnamon (CN) for 21 days. Basal diet alone was used as a negative control, and basal antibiotic diet (Colimox) was used as a positive control. At 10, 14, and 21 days of age, chicks that received 2000 mg CN and Colimox had a higher body weight, resulting in an increase in body weight gain. CN also resulted in the maximum improvement in the feed conversion ratio and feed efficiency over 1–21 days at the level of 2000 mg/kg. At days 10, the maximum relative breast weight was 2000 mg/kg of CN. Mean serum albumin concentrations, duodenal villus height, and goblet cell density increased (p < 0.05) by 2000 mg/kg of CN, and mean serum globulin and total protein concentrations and crypt depth increased (p < 0.05) by 6000 mg/kg of CN compared with control. Increased cecal Escherichia coli number was CN dose-dependent. In conclusion, dietary inclusion of 2000 mg/kg CN can be applied as an alternative to in-feed antibiotics for broiler starter diet.

Abstract Background An effort was made to assess the effectiveness of dietary supplementation of Ulva lactuca (U. lactuca), a seaweed and Azolla individually and in combination on different physiological parameters of Aseel chicken. A total of 40 Aseel chicks of 8 weeks old were allocated into four groups, C1 (control), T1 (Azolla alone), T2 (seaweed alone) and T3 (seaweed plus Azolla). Aseel chicks in C1 were fed with formulated grower feed alone, birds in T1 had control diet with 5% Azolla, birds in T2 had control diet with 3% U. lactuca and birds in T3 had control diet admixtured with 5% of Azolla and 3% of U. lactuca. Parameters were recorded for a continuous period of 2 months in 15 days interval. Results The growth performance was found to be significant (P ≤ 0.05) during 30 days of feed trials and highly significant (P ≤ 0.01) during 45 and 60 days of treatment. Birds in T3 had a higher body weight gain, shank length and feed conversion efficiency followed with T1 and T2 compared to C1. PCV, RBC, WBC and heterophil counts were not influenced (P ≥ 0.05) by dietary treatments. Uric acid, creatinine, AST, glucose, triglycerides and magnesium levels revealed a high significant (P ≤ 0.01) variation, and cholesterol level showed significant (P ≤ 0.05) changes during 30th and 60th day of feed trials between the control and treatment groups. Total protein, globulin, phosphorus and electrolytes like Na, K and Cl levels were not significant (P ≥ 0.05) during 30th day and were highly significant (P ≤ 0.01) during the 60th day of the trial. Conclusions It could be noted that inclusion of U. lactuca and Azolla as feed supplement in grower chicken had a better body weight gain when given in combination (U. lactuca and Azolla) rather than supplemented with the sole entity. Based on the haematological and serum biochemical analysis, the supplementation of U. lactuca and Azolla at the levels included in this trial did not pose any threat to the physiological well-being of Aseel chicken.
