Two groups of 200 broilers, strain ISA15, have been raised in the same building with the same ambient conditions, lighting, and feeding, during two periods, the first, in spring time (April- May). ) and the second in the autumn period (October-November).broilers received three vitamin treatments in the drinking water (chicktonic premix, vitE / selenium and antistress, betamint)from 1day to 48 day. In order to avoid cases of rickets or growth retardation, as well as breeding stress , all chickens in the summer treated with chicktonic as miltivitamin and betamint. The lots were identified according to the following therapeutic schema: control lot CH (chicktonic 1ml /, betamint 1ml / then 2ml / l from day 41). Lot CH + 41 (chicktonic 1ml / l then 2.5 ml / l from day 41, betamint, same as controllot ). Lot CH + 13 (chicktonic 1ml / l, then increasing the dose gradually from day 13). Lot VitE / Se + 41 (1ml / l then 2.5 ml / l from day 41, betamint, same as controllot ). Lot VitE / Se + 13 (1ml / l, then increase the dose gradually from day 13). Lot Bet + 13: chicktonic 1ml / l, betamint 1ml / l, then increase the dose gradually from day 13). The results obtained are significant at the p< 0.05, for live weight, yields, and blood profile. We obtained the best live weight (2821.33 g ± 229.77) with the increase in the dose of vitamin E / Selenium from day 41. Increased doses of chicktonic from day 41 improved performance, IC (2.08 ± 1.0) and IP (358.24 ± 313.25) and CV% (8.3), as well as serum cholesterol (1.23 g / l ± 0.17) and blood glucose (2.34 g / l ± 0.21), but carcass yield (74.70% ± 4.99) and that of organs are better when the doses were increased from day 13. Increasing the selvite dose from day 13 gave a lower IC (1.6 ± 1.6). The organ yield is better with the lowest abdominal fat yield (0.69 ± 0.28). The increase in dose of antistressBetamint, gave a high level of total protein (34.50 g / l ± 4.63), that of cholesterol (1.32 g / l ± 0.17) and that white blood cells (952.2610 ^ 3 / μl ± 26.60). With respect to the mortality rate, the three treatments gave low values between 0.10% and 0.33%.Diplôme : Doctorat en sciences En ligne : ../theses/veterinaire/CHO7467.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=11298 Influence de l’apporten vitamines et antistress sur les performances zootechniques et le profil hématologique chez le poulet de chair.

The number of the highest cases (45) has parasitemia between 0.1 - 4.99%. A total of 180 and 134 blood samples from 21 farms were collected in April and November 2015 (before and after the tropical theileriosis season; respectively) in the region of El Eulma (Sétif). Molecular prevalence (38.9 and 50% in April and November; respectively) was higher than those by Giemsa stained blood smear (17 and 16.4%, before and after tropical theileriosis season; respectively) (p<0.001 ). Exotic breeds were more infected than local breeds in the first visit (p=0.003), while during the second visit no significant difference was detected (p=0.226). This prevalence is lower in cattle less than one year (p=0,117; 0,270 in April and November; respectively). Molecular prevalence was significantly higher in females (44.7%) than in males (22.9%) (p<0.008) during the first visit.
No influence of type of livestock or the walls statements was detected. The sequences of genes Algerian Tams1 (96.1 to 98.9%, identity values) have a relationship with the Mauritanian, Tunisian and Egyptian sequences.
The biochemical and haematological study conducted on 40 healthy cattle and 40 clinically infected showed that the number of leukocytes, erythrocytes, haemoglobin, haematocrit, glucose, albumin, and total protein decrease significantly (p=0.005; 0.008, 0.03,0.048, 0.002, 0.027 and 0.018; respectively) in clinically infected Montbeliard breed with Theileria annulata. All infected animals have a total and direct bilirubin concentration increase significantly (p<0.001). The erythrocytes, haemoglobin, and haematocrit crossbreed cattle concentration decrease significantly (p=0.027; 0.003 and <0.001; respectively). Two types of anaemia were detected: hypochromic microcytic anaemia in Montbeliard clinically infected cattle and normochromic normocytic anaemia in infected local and cross breed cattle.
The tropical theileriosis impact study in Skikda region (northern Algeria) showed a decrease in milk production in 10 local breed cattle infected with Theileria annulata in summer 2015. The decrease in weekly milk production estimated for two months was 2.76 L /day / cow corresponding to 31.92% of the total milk production. This decrease corresponds to 110.5 AD (US $ 1.02) / day / sick cow. The relative variation of milk production showed a dramatic decrease from 82.72 to 0.76% on day 21.
