Bu çalışmanın amacı etlik piliçlerde akut sıcak stresinin hemotokrit değerleri ve lökosit komponentlerinin oranları üzerine etkisini saptamaktır. Etlik piliçlerin 44 gün yaşında 2 saat süreyle 39±1 C° sıcak stresine maruz kalmaları rektal sıcaklık, heterofil ve bazofil oranlarında artışa neden olmuştur. Etlik piliçlerin akut sıcak stresine maruz kalmaları monosit ve lenfosit oranlarında azalmaya sebep olurken, eosinofil ve hemotokrit değerleri etkilenmemiştir. Etlik piliçlerde vücut sıcaklığının artmasına neden olacak kadar yüksek çevre sıcaklığının lokosit komponentlerini de değiştireceği sonucuna varılmıştır.The purpose of the present study was to determine the effects of acute heat stress on the proportions of leucocyte components and hematocrit values in broiler chickens.

The aim of the present study was to investigate the effects of parental age and heat acclimation during incubation on BW, cloacal temperature, and blood acid-base balance in fast-growing broilers exposed to daily cyclic high ambient temperatures from 21 to 42 d posthatch. Eggs obtained from 32- (younger), 42- (middle-aged), and 65-wk-old (older) breeders were divided into 2 groups. One group of eggs was incubated at the control incubation temperature (IT(CONT)) and the second group was heat acclimated at 38.5 degrees C for 6 h/d from d 10 to 18 of incubation (IT(HA)). Chicks were reared at standard brooding temperatures from d 1 to 21. From d 21 to 42, half of the broilers per incubation temperature and parental age were kept as controls (AT(CONT)) and the other half were exposed to daily cyclic heat treatment (AT(HIGH)) to impose a stress response. The reduction in BW at AT(HIGH) was more pronounced for progeny from older compared with younger parents. However, this reduction in BW was more or less abolished for broilers from eggs incubated at IT(HIGH), implying an increased tolerance to heat stress. Compared with IT(CONT,) IT(HA) reduced BW of broilers from 32- and 42-wk-old parents while having no effect on those from 65-wk-old parents when reared at AT(CONT). Higher blood pH, and lower partial pressure CO(2) and HCO(3)(-) at AT(HIGH) were associated with greater cloacal temperatures throughout the heat stress from d 21 to 42. Increases in cloacal temperature by AT(HIGH) were greater for IT(CONT) than for IT(HA) broilers. The AT(HIGH) and IT(HA) broilers had lesser blood partial pressure CO(2) concentrations than AT(CONT) and IT(CONT), respectively. Although at AT(HIGH), blood HCO(3)(-) was lower for broilers from all parental ages, it was more pronounced for those from 65-wk-old parents. It is concluded that these changes in blood acid-base balance reflected adaptive responses to heat stress, and incubating eggs at IT(HA) improved thermotolerance of fast-growing broilers.

The experiment was conducted to evaluate the effects of dietary supplements of either an essential oil mixture (EOM) or a mannan oligosaccharide (MOS) as alternatives to an antibiotic feed additive (avilamycin) for layers kept under hot summer conditions. Four hundred and eighty 54-week old NickBrown hens were assigned to four dietary treatments. Each treatment consisted of four replications of 10 cages (three hens per cage). The treatment groups were: 1) Control: Basal diet without additive; 2) Basal diet plus antibiotic (10 mg avilamycin/kg feed); 3) Basal diet plus 1 g MOS/kg feed; 4) Basal diet plus 24 mg EOM/kg feed. Performance of laying hens was affected by dietary treatments. Dietary supplementation of EOM and MOS significantly increased egg production compared with control and antibiotic groups. There were no significant differences in feed consumption between treatments. The EOM significantly improved feed conversion ratio above that of the control group. Egg weights were ...

The objective of this study was to investigate the effect of intermittent feeding on growth performance and stress related parameters of turkey toms from a heavy commercial line. Lighting schedule was 14L:10D during the experiment. In intermittent group, cyclic 2h duration of feeding was applied to birds during daily photophase from day 10. Body weight, body weight gain and feed consumption didn’t differ with treatment. The restricted group had improved FCR between 10-17 d. Significantly higher basophile numbers were observed in restricted group at 12 d. At 28 d, heterophils were significantly (P<0.05) and H/L ratios were numerically higher in restricted group, while eosinophils lower than ad libitum group (P<0.05). Leucocyte responses to intermittent feeding showed the severe stress effect of intermittent feeding on turkeys at start and a mild stress at 28 d and no effect of feeding onward. These results may refer that turkey toms adapted to feeding manipulation by six wk. Fe...

ABSTRACT The aim of this study was to examine the effects of herbal essential oil mixture on intestinal mucosal development, weights of the internal organs, carcass characteristics, and growth performance of quail (Coturnix coturnix japonica). A total of 276 quails that were 1 day old were studied. The quails were weighed and divided into 3 groups, each with 4 replicates, consisting of a control, antibiotic (avilamycin 10 mg/kg diet), and the essential oil mixture (EOM) at 48 mg/kg diet. Supplementation with EOM and antibiotic significantly increased goblet cell size and goblet cell number on day 38. Villi height, villi width, and crypt depth were not affected by any treatment. Quails receiving the diet containing EOM and antibiotic were significantly heavier than those fed the control diet on days 28 and 38. No significant effects of the dietary treatments on feed intake were observed. Moreover, addition of EOM and antibiotic to the quail diet resulted in a significantly better feed conversion ratio than that of the control on days 28 and 38. No differences were observed for carcass yield or liver, gizzard, and small intestine weights. Beneficial effects of the EOM were observed in goblet cells of the intestinal mucosa.

This experiment was conducted to study the effects of different levels of full fat canola seed low in glucosinolate and erucic acid on the performance of 336 day old quail (Coturnix coturnix japonica). The experiment was performed in a completely randomize design with three treatment and four replicates for each treatment. The experimental treatment included 5 and 10 % full fat canola seed in diet and fed to quail from 1 to 42 days of age. All of the experimental diets were iso-caloric and iso-nitrogenous. The mean total body weight was not significantly influenced by canola seed inclusion levels. But feed intake and feed conversion ratio were significantly increased by supplementation of 10 % full fat canola seed to the diet. Percentage of liver, proventriculus, gizzard, carcass to body weight was not significantly affected by canola seed inclusion levels. But small intestine rate was significantly increased by supplementation of 10 % full fat canola seed to the diet. As a result, ...

One hundred and sixty-eight 11-week-old laying quails (Coturnix coturnix japonica) were fed one of the following three diets: (1) control: basal diet with no lentil (Lens culinaris L.) byproduct; (2) inclusion of 10% lentil byproduct; (3) inclusion of 20% lentil byproduct. In the recent years, colour sorting machines are used in order to separate red lentils according to their colours. The goal is to select the items which are discoloured, not as ripe as required, or still with hull even after dehulling of lentil seed. During the sorting, a new byproduct called "sorting byproduct" leftover is obtained. The byproduct is cleaner and is of a higher quality than other lentil byproducts. This experiment was conducted to study the effects of the inclusion of different levels of lentil byproduct on laying quail performance. The experimental treatment included 10% or 20% lentil byproduct in the diet, and this was fed to quails aged between 11 and 22 weeks. The inclusion of 10% and...

The aim of this study was to evaluate the interaction between various widely used intraocular lenses (IOLs) and silicone oils of different viscosities. Four groups of IOLs, including monoblock foldable hydrophilic acrylic IOLs (Morcher, type 92s); monoblock hydrophobic acrylic IOLs (Acrysof-SA60AT, Alcon); single-piece rigid polymethylmethacrylate (PMMA) IOLs (Intraocular Optical International-IOI-65130) and a three-piece foldable silicone optic IOL (CeeOn Edge 911A, Pharmacia UpJohn) were analyzed in vitro to determine the percentage adherence 1,000-centistoke, 1,300-centistoke or 5,000-centistokes silicone oil on the IOL optic. For each IOL type, there was no statistically significant difference in the mean silicone oil coverage (MSC) of the IOL optics for the different viscosities of silicone oil. Silicone IOLs had the highest MSC percentage (79.9%) whereas hydrophilic acrylic IOLs were the least silicone-covered IOLs (7.8%) compared to the other IOL types tested in this study. It is not the concentration of silicone oil that affects silicone oil coverage. When performing small-incision cataract surgery in patients who may require silicone oil injection, foldable hydrophilic acrylic or hydrophobic acrylic lenses should be preferred over standard foldable silicone lenses.

ABSTRACT The aim of this study was to investigate the effect of diet type, supplementation diet with an essential oil mixture (EOM), and bird gen-der on the growth performance, carcass yield, internal organ weight, immune response, and small intestine histology of broiler chickens. To do this, a 2¥2¥2 factorial arrangement was designed. The variables used were: two diet types (based on either wheat or corn), 2 feed additives (with or without EOM), and gender (male or female). EOM supplementation in the diet decreased body weight in corn-fed male birds at Days 21 and 42, but not in those fed the wheat-based diet, signifying a diet ¥ EOM ¥ gender interaction. Cumulative feed intake was not influenced by either the diet type or EOM. The feed conversion ratio was not affect-ed by diet type, whereas EOM improved feed conversion ratio over the 42-day growth period. Feeding birds on wheat decreased the carcass yield while it increased relative small intestine and large intestine weight. Relative weights of liver, bursa fabricius and serum infectious bur-sal disease (IBD) and Newcastle disease (ND) titers were not affected by any of the variables studied. EOM supplementation and feeding birds on corn increased jejunal villus height at both 21 and 42 days of age, while bird gender showed no effect. In general, EOM positively influenced body weight gain and efficiency of feed conversion in broiler chickens. Birds receiving the corn-based diet were more effi-cient in converting feed to body mass as com-pared to those fed on the wheat-based diet.

ABSTRACT The role of dietary supplemental mannan oligosaccharide (MOS) and an essential oil blend (EOB) on performance of laying hens, and susceptibility of egg yolk and hen liver to lipid oxidation were examined. Four hundred and thirty-two 52-week old Lohmann laying hens were divided into three groups and fed a basal diet containing no antioxidant as control (CNT), basal diet plus 1 g/kg MOS and basal diet with 24 mg/kg EOB, for a 10-week experimental period. Supplementation of diet with MOS and EOB improved egg production rate and eggshell weight, but did not influence other performance or egg quality traits. MOS and EOB provided higher antioxidant activity in egg yolk than the control regimen at all storage time periods. EOB also retained the oxidative stability of liver by measuring malondialdehyde (MDA) levels. Liver antioxidant enzymes, including superoxide dismutase (SOD) and glutathion peroxidase (GSH-Px), were higher in birds fed the additives. MOS and EOB tended to increase serum glucose concentration (6.2% and 8.8%, respectively) while they slightly decreased triglycerides (11.0% and 4.8%, respectively) without affecting cholesterol level. Relative weight of pancreas and spleen were not affected by dietary treatments whereas diet supplemented with EOB significantly increased liver weight. The findings of this study suggest that EOB and MOS could act as free radical scavengers that enhance performance and also increase eggshell weight.
