Abstract

In the present study its used liquid preparation of probiotics "Vetlactoflorum-M" (dissolved in diluted milk) and "Vetlactoflorum-C" (dissolved in whey), and were studied its effect on some parameters such as total protein, globulin, albumin also serum bactericidal and lysozyme activity.One hundred fifty broilers chicken breed "Ross-308" used in one day old. They were divided into three groups of 50 chicks (control" un-supplemented with probiotic" , first treatment group received “Vetlactoflorum-C” and second treatment group received “Vetlactoflorum-M”). Blood samples were taken in 7, 14, 21, 28, 35 and 42 day-old. Laboratorial analyses were conducted in Vitebsk state academy of veterinary medicine in Belarus. Level of total protein in the 2nd group to the end of the study was higher than in control group to 8.1% (P <0.05) in the third group by 3.96% (P <0.01). During observation period in chicken’s serum of supplemented probiotic groups, albumin concentration was higher relative to the control group. Similar results were observed in level of globulins. In day 42 of broilers chicken, globulin content in both treatment groups compared with the control group as higher by 2.97% (P<0.01) and 5.19% (P <0.05), respectively. The level of serum bactericidal activity in 42 day of 2nd group was higher than the control at 23.62% (P <0.01), and in the third group by 16.21% (P> 0, 05). The index of serum lysozymal activity also surpassed control group in chickens in group 2 by 11.96% (P> 0.05), and in the third group at 10.69% (P> 0.05).

في الدراسة الحالية استخدم مستحضر سائل من "Vetlactoflorum-M" الذائب في الحليب، و " Vetlactoflorum-C" الذائبة في شرش الحليب، و درست تأثيره على بعض المقاييس مثل البروتين الكلي والكلوبيولين والالبومين و كذلك النشاط القاتل للبكتريا والحال في مصل الدم. اخذت 150 فروج لحم من سلالة "روس-308" في عمر يوم واحد ، وقسمت إلى ثلاث مجموعات كل مجموعة تتكون من 50 فروجة لحم (مجموعة السيطرة لم تعطى المعزز الحيوي) ومجموعة المعالجة الاولى التي اعطيت المعزز الحيوي "Vetlactoflorum-C" ومجموعة المعالجة الثانية التي اعطيت المعزز الحيوي "Vetlactoflorum-M ". تم أخذ عينات الدم في عمر 7 و 14 و 21 و 28 و 35 و 42 يوما. أجريت الدراسة في مختبرات اكاديمية فيتبسك الحكومية للطب البيطري في روسيا البيضاء. كان مستوى البروتين الكلي في المجموعة الثانية حتى نهاية الدراسة أعلى من مجموعة السيطرة بحوالي 8.1٪ (P <0.05) في مجموعة التجربة الثالثة 3.96٪ (P <0.01) . خلال فترة المراقبة لوحظ في مصل دجاج اللحم للمجموعتين اللتين اعطيت المعزز الحيوي ان تركيز الألبومين أعلى نسبة بالمقارنة مع مجموعة السيطرة. ولوحظت نتائج مماثلة في كمية الجلوبيولين. في عمر 42 يوم كان مستوى الكلوبيولين في كلا مجموعتي المعالجة (الثانية والثالثة) بالمقارنة مع مجموعة السيطرة كان مرتفعا بنسبة 2.97٪ (P <0.01) و5.19٪ (P <0.05) على التوالي. وكان مستوى نشاط القاتل للجراثيم في مصل الدم في 42 يوم من مجموعة التجربة كان أعلى من مجموعة السيطرة بحوالي 23،62٪ (P <0.01)، وفي المجموعة الثالثة بحوالي 16.21٪(P <0.05). تجاوزت مؤشر النشاط الحال في المصل أيضا مجموعة السيطرة في افراخ الدجاج في المجموعة الثانية من 11.96٪ (P> 0.05)، وفي المجموعة الثالثة في 10.69٪ (P> 0.05).

Abstract

Locally prepared vaccine, precipitated with alum and sodium hydroxide (IAPSHV) in embryonated chicken eggs. Different programs were carried out to evaluate its efficacy. Two hundred and fifty broiler chicks were divided equally into five groups. Different vaccination programs were used a follow. G1: vaccinated with live attenuated vaccine (B1) by intraocular route at 1, 10, 17 and 27 days of age. G2: vaccinated with live attenuated vaccine (B1) by intraocular route at 1 day of age and vaccinated also with (IAPSHV) at 1 day of age. G4: Vaccinated with (IAPSHV) only, by subcutaneous route at 1 day of age. G5: Control group left with out any vaccine. Indirect (ELISA) and Haemagglutination inhibition tests (HI) were used for evaluation of antibodies titer before and after vaccination, challenge test also used with virulent strain of Newcastle disease virus. Results showed that G3 gave the highest titer by both ELISA and (HI) test and low mortality in challenge test. It was concluded that (IAPSHV) at 7 day of age with attenuated live vaccine at the same age gave the best result than other groups. The applied program, and (IAPSHA) vaccine is recommended.

Abstract

This study was designated to investigate the effect of light color and stocking density on some productive performance of broilers. A total of 675 Ross 308 one-dayold broiler chicks were used in this study. The birds were exposed to white light (WL) as a control , red light (RL), blue light (BL), green light (GL), and Blue – Green mix light (BGL) by a light-emitting diode system (LED) applied for 24 hours daily in separated rooms. The birds were randomly divided and housed into 9 wooden sealed pens of 1m2in three replicates for each density 12, 15 and 18 birds/m2in the room. The results showed that the broilers reared under BGL significantly increased (P< 0.05) body weight (BW) and weight gain (WG) at 1st, 3rdand 5thweek. Obviously, stocking density had no significant effect on BW and WG at 1stweek but significantly increased under 12 birds/m2at 3rdand 5thweek. Feed intake (FI) recorded a significant increase (P< 0.05) in broilers reared under WL at 1stweek, but no statistical difference was found at 3rdweek whereas, FI significantly increased (P< 0.05) in broilers reared under BL at 5thweek. The stocking density affected FI values which were significantly differed (P< 0.05) at 1st, 3rdand 5thweek under 12 birds/m2compared with other densities. The results of the study revealed a significant increase (P< 0.05) of Feed conversion ratio (FCR) in broilers reared under BL at 1stweek and RL at 3rdweek but there was no significant difference between groups at 5thweek. The results indicated a significant difference of FCR value in 18 birds/m2at 1st week but there were no significant differences at 3rdand 5thweek at different densities. In conclusion, the results of this study indicated that chickens reared under five different color lighting schedules with three bird densities showed that broilers reared under mixing blue – green light under 12 birds/m2has a significant positive effects on production performance compared with other light programs and bird densities

Abstract

Two groups of broiler chickens were used in this study. One was reared under typical conditions at the animal house of Veterinary Medicine College/Mosul University- Iraq, while the other group was reared under common commercial farm conditions. Fifty and 80 birds from the two respective groups were sacrificed at 49 days of age for detecting Toxoplasma gondii by using Species-specific PCR technique. Results of Latex agglutination test indicated, principally, that 29.3% and 49.2% of the serum samples were positive for the birds of both groups, respectively. Titer figures ranged between 1:20 to 1:320 where the highest value was 1:160 (39.3%) and the lowest was 1:20 (5.8%). Confirmation of 38 and 64 serum samples, using Latex agglutination test was performed by PCR technique, from the two respective groups of chickens. Of those, 8 samples from the college birds and 35 from the commercial farm birds were confirmed positive by giving band of 133 bp, according to specific primers designated on gene B1.Based on these results, pursuing the PCR technique is considered, so far, a most sensitive method for Toxoplasma gondii detection. Also, positive PCR results are counted on as an early marker for reactivation and useful means in monitoring therapies.

Abstract

Seventy five broiler chicks were used to determine the immunization of in ovo inoculation or intramusclular (I/M) injection of sonicated oocyts (SO) antigen against E. tenella manifestation. The chicks were divided in to 3 equal groups compromising of 25 chicks each. The 1st group inoculated in ovo with SO of E. tenella and repeated by I/M injection at 21 days old. The 2nd group injected I/M with SO at day old and repeated at 21 days old, The birds of the 3rd group remains as control. All birds were challenge by 50,000 sporulated oocysts of E. tenella at day 28. No significant (P > 0.05) group difference was detected between the immunized and non-immunized groups for mean, WBC count, H/L ratio, lesion score, mortality and oocysts shedding until E. tenella challenge at day 28. After challenge test the in ovo and I/M immunized groups showed a great protective immunity against E. tenella infection documented by significantly (P < 0.05) reduced mortality, lesion score and decreased fecal oocyst shedding, compared with non-immunized group. It is concluded that in ovo and I/M immuinzation of sonicated oocyst stimulates a remarkable protection in broilers following E. tenella infection comparing with non-immunized groups. There was no significance difference between the two procedures of immunization.

Abstract

Abstract: Nigella sativa (Ns) has been employed for thousands of years as a spice and food preservative and commonly used in folk medicine all over the world for the treatment and prevention of a number of diseases and conditions. The aim of the study was as an attempt to investigate the effect of Ns meal on the oxidative stress (OS) following intra-tracheal (IT) administration of an air pollutant benzo[a]pyrene (BaP) in broiler chickens. At day one of age, chicks were divided into four groups comprising of 24 birds each, as controls, Ns, BaP-only, and BaP with Ns. The antioxidant function of glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) in RBCs hemolysate and liver tissue homogenate in the group receiving BaP alone demonstrated evidence of OS, and oral supplementation of Ns was significantly reduces these alterations with potent effects seen after 21 to 35 days in treated group which is a key finding from this study. It is concluded that exposure to BaP may exert adverse effects on the erythrocyte and liver antioxidant enzymes of broilers which may increase their susceptibility to disease infection, with a disastrous outcome and oral supplementation of Ns was significantly reduces these effects.
