“…It is clearly observed that pullets fed diet supplemented with biotin at a level of 150 µg/ kg and 100 µg/ kg recorded the higher averages of plasma calcium and inorganic phosphorus levels (6.97 and 3.79 mg/ dL, respectively) compared with the other biotin levels and control group. This result agrees with those reported by Afro et al, (2007) who stated that, the serum calcium and phosphorus levels were significantly higher in of birds fed on diet supplemented with biotin at a level of 300 μg/ kg diet compared to control group. Plasma calcium and inorganic phosphorus has significant varied due to the different periods of estimation, the higher plasma calcium and inorganic phosphorus (6.74 and 3.55 mg/ dL, respectively) were found at the end of experiment.…”

This study aimed to investigate the effect of housing system and dietary biotin supplementation on productive performance, blood biochemical parameters and economic efficiency of Benha line chicken. A total of 224 chickens, 20 weeks old with similar body weight were used in this study, birds were equally divided into two main groups in a factorial arrangement design (2x4x3). Pullets of the first group reared in cages. While, pullets of the second group reared on deep litter. The pullets of each group were subdivided into four subgroups (each of 25 females and 3 males) according to dietary biotin supplementation. Birds of the 1 st subgroup were fed on basal layer diet and considered as control, while the 2 nd , 3 rd and 4 th subgroups fed basal diet supplemented with biotin at levels of 100, 150 and 200µg /kg feed, respectively. The results revealed that, pullets reared in cages significantly improve body weight, feed conversion, early to reach age at sexual maturity, egg production rate, egg weight, egg mass, absolute yolk weight compared to those reared on deep litter. While, pullets reared on deep litter had significantly improved feed consumption, egg shell thickness, plasma calcium, inorganic phosphorus and decreased plasma cholesterol and triglycerides compared to those reared in cages. Biotin supplementation at a level of 100 µg /kg feed had significantly increased body weight, egg weight, absolute and relative egg albumen weight, plasma inorganic phosphorus and decreased feed consumption compared to the other levels. While, pullets fed on diet supplemented 150µg biotin /kg feed showed the improving in feed conversion, early sexual maturity, increased egg production, egg mass and plasma calcium compared with the other levels. In addition, birds fed diet supplemented with biotin at a level of 150 µg/kg feed and reared in cages recorded the highest economic efficiency (219.04%), followed by those fed diet supplemented with biotin at a level of 100 µg/ kg feed and reared on deep litter (141.37 %) compared to the other levels and control group. From the economic point of view, it could be concluded that rearing layer chickens in cages and fed on diet supplemented with biotin at a level of 150µg/kg feed seemed to be adequate to achieve the favorable results, followed by those reared on deep litter and fed diet supplemented with biotin at a level of 100 µg/ kg diet.

“…Choline is a well-known lipotropic factor responsible for the mobilisation of liver fat in the form of lipoproteins toward extra-hepatic tissues where they may be metabolised or deposited [ 42 , 43 ]. As a result, the excess fat energy gets diverted towards muscle protein accretion rather than body fat synthesis, resulting in better growth, improved FCR and lower lipid content in liver, abdomen, and carcass [ 37 ].…”

ObjectiveThe study was designed to establish choline deficiency model (CDM) in broilers for evaluating efficacy of polyherbal formulation (PHF) in comparison with synthetic choline chloride (SCC).MethodsA total of 2,550 one-day-old Cobb 430 broiler chicks were randomly assigned to different groups in three experiments. In experiment 1, G1 and G2 served as normal controls and were fed a basal diet with 100% soybean meal (SBM) as a major protein source supplemented with and without SCC, respectively. In G3, G4, G5, and G6 groups, SBM was replaced at 25%, 50%, 75%, and 100% by soy protein isolate (SPI) to induce a graded level of choline deficiency. In experiment 2, PHF (500 and 1,000 g/ton) in comparison with SCC (1,000 g/ton) were evaluated. In experiment 3, dose-response of PHF (200, 400, and 500 g/ton) with SCC (400 g/ton) was determined.ResultsReplacement of SBM by SPI produced a linear decrease in body weight gain (BWG) with a poor feed conversion ratio (FCR). 25% SBM replacement by SPI yielded an optimum negative impact on BWG and FCR; hence, it is considered for further studies. In experiment 2, PHF (500 and 1,000 g/ton) and SCC (1,000 g/ton) showed a similar performance in BWG, FCR and relative liver weight. In experiment 3, PHF produced an optimum efficacy at 400 g/ton and was comparable to SCC in the restoration of serum aspartate aminotransferase activity, abdominal fat, breast muscle lipid content and liver histopathological abnormalities.ConclusionReplacement of SBM by SPI caused choline deficiency characterised by worsening of BWG, FCR, elevation in liver enzymes and histopathological changes indicating fatty liver. CDM was found valid for evaluating SCC and PHF. It is concluded that PHF has the potential to mimic biological activities of SCC through the restoration of negative effects caused by CDM.

“…In contrast, tibia widths of male and females broilers at 32 and 48 days of age were changed between 6.20-6-50 mm and between 8.44-9.07 mm (Yalcin et al 2001). In a study by Quarantelli et al (2007), lengths of femur bone at 21, 41 and 61 days of age as 51. 40-54.57mm, 75.50-79.87mm and 90.50-97.37mm, but lengths of tibia bone as 72.47-96.0mm, 107.5-114.5mm and 132.43-140.83 mm were determines, respectively.…”

The aim of this research was to determine the effects of thermal manipulations early and late embryogenesis on growth of tibia and femur bones of broilers. For control group eggs 37.5 o C and 55 % humidity were applied on the incubation during 19 days. Incubation temperature was increased to 41 o C and humidity to 65 % for 3 hours on the 8 th-10 th days of incubation during early embryogenesis. Similarly, incubation temperature was increased to 41 o C and humidity to 65 % for 3 hours on the 16 th-18 th days of incubation during late embryogenesis. Average tibia bone lengths were determined as 97.57 mm, 99.08 mm and 100.25 mm for control, early and late embryonic groups, respectively, and significant difference were determined between the average values. Also, male broilers (100.27 mm) have higher tibia bone length than females (97.66 mm). The differences between the groups in point of femur bone length was significant, and the highest femur bone length was in the late embryonic group (70.79 mm), the lowest femur bone length in the control (68.93 mm) group.
