Abstract: The forced molting in commercial laying hens had being utilized for get better the performance of birds for one more cycle of production of eggs. The experiment was aimed at evaluating the intestinal biometric parameters in laying hens submitted to the different forced molting program. Third two Hisex Brown laying hen with 58 weeks of age were randomly subdivided into four programs (P1- California program; P2- diet of low-calcium; T3- diet of high-zinc and P4- diet of low-sodium) in two replications constituted of four birds each. The biometric parameters occurred at 28th and 140nd days and for this, four birds were sacrificed of each program in the period cited. The bird corporal weight and the relative weight of the intestine (duodenum, jejunum, ileum, cecum and rectum) were obtained on electronic precision scales and the lengths were measured. The data were submitted to the variance analysis and in case of significant difference; the averages were compared by the Tukey′s test. It was observed the commercial laying P1 and P3 the smallest mean body and relative weights (no significant) and lengths in relation to the chickens P2 and P4 and to the 140th days the corporal weight, relative weight and length of the intestine of chickens were larger. Concluded that the different programs of forced molting presented similar results and they can be used for commercial laying hens in second production cycle.

A muda for ada em poedeiras comerciais tem sido utilizada para melhorar o desempenho zootécnico das aves por mais um ciclo de produ o de ovos. O experimento foi realizado com o objetivo de avaliar a biometria do intestino de poedeiras comerciais submetidas a diferentes programas de muda for ada. Trinta e duas aves da linhagem Hisex Brown com 58 semanas de idade foram distribuídas em um delineamento inteiramente casualizado, constando de quatro programas de muda for ada (P1- programa Califórnia, P2- baixo nível de cálcio; P3- alto nível de zinco e P4- baixo nível de sódio) e duas repeti es de quatro aves cada. As medidas biométricas ocorreram ao 28o e 140o dias e, para isso, quatro aves foram sacrificadas de cada programa, em cada período, para a avalia o do peso corporal e do peso relativo das diferentes por es intestinais (duodeno, jejuno, íleo, ceco e cólon-reto) por meio de uma balan a de precis o e do comprimento dos intestinos com o auxílio de uma fita métrica milimetrada. Submeteram-se os dados obtidos à análise de variancia e, em caso de diferen a significativa, compararam-se

Abstract: In order to study the effect of turmeric rhizome powder (TU) and enzyme in some blood parameters of laying hens, an in vivo study was conducted. In a 5 * 2 completely randomized block design with factorial arrangement, 5 levels of TU (0.0, 0.05, 0.10, 0.15, and 0.20 %) and 2 levels of enzyme (0.0, and 0.05%) with 4 blocks (replicate) , 480, 100-week old laying hens for 4 weeks fed wheat-soybean meal based diets. Some serum blood parameters of laying hens including hematocrit value, triglyceride, total cholesterol, HDL and LDL-cholesterol were recorded at 104 weeks of age. Increasing dietary levels of TU with or without a dietary enzyme significantly decreased serum triglyceride, total cholesterol and LDL-cholesterol (P< 0.05). TU without enzyme significantly increased HDL-cholesterol. It was concluded that dietary supplementation of TU improves some of good indices of serum blood components in laying hens and might be used as an ingredient in laying hen diets for manipulating egg composition.

Abstract: This experiment was performed to compare the effects of fermented soybean meal (fermented with Bacillus licheniformis D-1, FSBM) and Soybean Meal (SBM) on performance, serum biochemical parameters and intestinal morphology of laying hens. About 288, 29 weeks old laying hens were randomly allocated into 2 dietary treatments, 4 replicate groups of 36 laying hens each from 29-39 weeks of age. One treatment received the basal diet (containing 22.8% SBM) as control and the other treatment received the basal diet in which the SBM was replaced by FSBM at 2.5%. At the end of feeding trial, 8 layers of each treatment were killed and their serum and small intestine segments of duodenum, jejunum and ileum segments were collected for serum biochemical parameters and intestinal morphology evaluation. Results showed that FSBM improved performance of laying hens. The laying rate was improved by 3.59% (p<0.05). Feed/egg ratio was decreased by 4.00% (p<0.05). Hens fed FSBM had lower levels of serum urea nitrogen (p<0.05) and a higher content of serum total phosphorus (p<0.05). Birds fed FSBM had a higher level of serum IgA and IgG than birds fed entire SBM (p<0.05). FSBM increased (p<0.05) villus height and villus height to crypt depth ratio in the duodenum and jejunum compared with whole SBM. There were no effects of FSBM on hen s ileum mucosa morphology. Therefore, it was concluded that FSBM had beneficial effects on performance of laying hens and thus, decrease or overcome the negative effect of SBM on egg-laying hens.

Abstract: The study examined effects of supplementing Roxazyme G and Maxigrain to wheat offal-, corn bran- and brewery dry grain-based diets on the performance, haematological parameters and economy of production in laying hens. Both enzymes were added to these 3 diets at 100 mg/kg, while control group was neither supplemented with Roxazyme G nor Maxigrain . The results showed that hens fed Roxazyme G corn bran diets had the best feed conversion and maximum profit. Maxigrain also significantly improved hen day production and egg weight of hens fed Brewery Dry Grain (BDG) than those fed Roxazyme G BDG diet. Laying hens fed BDG diets had the lowest profits. Both enzymes failed to improve the performance and profits of hens fed Wheat Offal (WO) diet. Improvements in Red Blood Cells (RBC) for hens fed both enzyme supplemented diets were observed. Interactive effects of enzyme type and fibre source significantly (p<0.01) influence RBCs, PCV and white blood cells. The study revealed that Roxazyme G and Maxigrain should be added to respectively CB- and BDG- diets for improved laying performance. However, these enzymes failed to improve the laying performance of hens fed WO diet.

Abstract: A study was conducted to determine the effect of, as a source of inulin, Jerusalem artichoke on intestinal pH, some blood parameters and liver enzymes of laying hens. Control and treatment groups were fed a diet containing 0, 5 and 10% Jerusalem artichoke, respectively. Twenty five weeks old, 45 commercial white laying hens were used in the experiment. In this experiment, inulin was effective on modifying of intestinal characteristics, blood metabolites and liver enzymes in laying hens. Fecal and intestinal pH values were not altered by dietary treatments. Although, unchanged serum cholesterol and albumen content, 5% JA increased glucose (p<0.001) and decreased fructose (p<0.01), triglyceride (p<0.01) and total protein (p<0.05) contents when compared with control diet. On the other hand, 10% JA reduced serum glucose as well as fructose levels. Serum SGOT levels was increased (p<0.01) by 5% JA addition and ALP levels was decreased (p<0.05) by 10% JA.

Abstract: This research has been performed to determine the effects of Hazelnut Oil (HO) and Sunflower Oil (SO) added in the layer ration at various levels as an energy source onto lipid peroxidation and blood parameters of laying hens. Eight hundred laying hens at 135 days of age were used as research material in this experiment. The hens were divided into 5 groups and then each group was divided into 10 subgroups containing 16 hens each. No oil was added in feeds of control group. The other groups were given 15 g kg 1 HO; 15 g kg 1 SO; 30 g kg 1 HO and the last one was mixed oil given 30 g kg 1 MO (15 g kg 1 HO + 15 g kg 1 SO). No difference has been observed in terms of Malondialdehyde (MDA), Glutation (GSH), Total Cholesterol (TCH), mean corpuscular volume (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Cell Volume (MCV), glucose, White Blood Cells (WBC), Red Blood Cells (RBC), Hemoglobin (HB), Packed Cell Volume (PCV) and Thrombocyte (TB) values among the groups. The source and level of the oil used in this study did not affect lipid peroxidation and hematological values.

Abstract: A study was conducted to evaluate dried berberry fruit (DBF) and enzyme on some blood parameters of laying hens. In a 5 * 2 completely randomized block design with factorial arrangement and 4 blocks as replicate, 5 levels of DBF (0.0, 0.5, 1.0, 1.5, and 2%) and 2 levels of NSP-degrading enzyme (0.0, and 0.05%) in wheat-soybean based diets were tested in 480, 100-week old laying hens for 4 weeks. Some blood parameters of laying hens including hematocrit value, triglyceride, total cholesterol, HDL and LDL-cholesterol were recorded at 104 weeks of age. DBF significantly (P< 0.05) changed hematocrit value and HDL-cholesterol (with or without enzyme), and LDL-cholesterol (with enzyme). It was concluded that use of DBF as a phytochemical compound may improve some of the blood parameters and possibly egg components that are important for human health.

Abstract: An experiment was conducted to determine the effect of dietary factors on induction of fatty liver hemorrhagic syndrome (FLHS) and its diagnosis methods with use of selected serum enzymes on Hy-line W-36 hens. The experiment was conducted in completely randomized design with 6 treatment groups and 4 replicates each with ten hens from 94 to 106 wk of age. Three 28-d periods used for different dietary factors including:1) Control (C); 2) Low methionine (LM); 3) Low linoleic acid (LLA); 4) High energy (HE); 5) Low methionine, linoleic acid, choline and high energy (LM-LLA-LCH-HE) and 6) Low choline (LCH). Feed intake, body weight, egg production (EP), egg weight, egg quality, serum and liver parameters were measured at the end of each 28-d periods. Overall feed intake was significantly (P< 0.05) lower for the hens fed HE diets compared to the control. Overall egg weight was significantly (P< 0.05) lower for the hens fed LM and LM-LLA-LCH-HE compared to the control. Overall Liver weight was significantly (P< 0.05) higher for the hens fed LLA and LM-LLA-LCH-HE compared to the control. Liver hemorrhage score (LHS) was positively correlated (P< 0.05) with liver weight. Serum enzyme activities including: aspartate aminoteransferase (AST), alanine aminoteransferase (ALT), lactate dehydrogenase (LDH) were not significantly affected by treatment groups. Although the AST enzyme activity was not significantly different, but it was numerically higher for all dietary treatments except HE diet. The results showed the effectiveness of dietary factors on induction of FLHS in laying hens. AST enzyme activity could be used for diagnosis of FLHS in laying hens.
