This study was conducted to determine the effects of different levels microalgae Chlorell sp. on performance of laying hens under heat stress condition. A completely randomized design experiment, with 7 replicates and 6 treatments (9 birds per replicate) was carried out by allotting 378 white Lohman strain laying hens at 65 weeks of age. Six experimental treatments were continual addition of 0, 100, 200, 300,400 ppm microalgae Chlorell and 400 ppm toein to drinking warer were fed to laying hens for 9 weeks. Egg production, egg weight, egg mass output and feed intake were determined. Antibody production against sheep red blood cells (SRBC) also was measured. Data  were  analyzed  by  ANOVA  using  General  Linear Models procedure of  SAS software and comparison of means  were  compared  using  Duncan’s  multiple  range test. The results of this experiment showed that microalgae Chlorell had no effect on productive performance. Adding microalgae Chlorell to the drinking water improved immune response of laying hens and a more positive effect was observed when 400 ppm added to the water. It is concluded that the addition of microalgae Chlorell to the water drinking of laying hens improved immune response of laying hens.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12058 International Journal of Life Sciences 9 (2) : 2015; 71-74

Abstract The current study was carried out on a poultry farm which belongs to the Animal production department - College of Agriculture - University of Kufa, for a period of 35 days started from October 10 to November 13, 2020 for 5 weeks to find out the effect of adding different levels of turmeric root powder and carnation flowers to the diet on some productive traits of broilers. in the experiment, 360 broiler chicks were used, one-day-old Ross-308 hybrid, The chicks were divided randomly into 6 treatments (60 chicks/treatment) by 3 replicates per treatment, with 20 chicks for each with an average initial weight of 40gm and the treatments were as follows: 0, 3, and 5 gm/kg diet of turmeric root powder for treatments T0, T1, T2, as well as 3 and 5 gm/kg diet fodder of carnation flower powder for treatments T3 and T4, respectively.

This study was conducted to estimate the effect of adding different levels of turmeric powder and curcumin on broiler performance, carcass traits, and immunity response and jejunum histology. A total of 750 Ross day old chicks obtained from a local hatchery and distributed into two rearing conditions (normal and heat stress condition) with five treatments 3 replicate for each one had (25 chicks). Dietary supplements of turmeric powder and curcumin significantly (P ≤ 0.05) improved performance under normal and heat stress conditions. Moreover, treatments significantly (P ≤ 0.05) increased the total titter antibody against Newcastle and infectious bursal disease compared to control. Concerning histology of jejunum treatments significantly (P≤0.01) improved jejunum histology. Regarding the effect of rearing condition heat stress conditions significantly (P ≤ 0.01) decreased performance compared to normal rearing condition. Small intestine percent from live body weight significantly (P ≤ 0.01) decreased compared to normal rearing conditions. Moreover, heat stress significantly (P≤0.01) affected the total antibody titer against Newcastle disease and infectious bursal disease. Jejunum histology significantly (P ≤ 0.01) affected by rearing conditions.

AbstractUnderstanding the mechanism for heat tolerance is important for the hot pepper breeding program to develop heat-tolerant cultivars in changing climate. This study was conducted to investigate physiological and biochemical parameters related to heat tolerance and to determine leaf heat damage levels critical for selecting heat-tolerant genotypes. Seedlings of two commercial cultivars, heat-tolerant ‘NW Bigarim’ (NB) and susceptible ‘Chyung Yang’ (CY), were grown in 42 °C for ten days. Photosynthesis, electrolyte conductivity, proline content were measured among seedlings during heat treatment. Photosynthetic rate was significantly reduced in ‘CY’ but not in ‘NB’ seedlings in 42 °C. Stomatal conductivity and transpiration rate was significantly higher in ‘NB’ than ‘CY’. Proline content was also significantly higher in ‘NB’. After heat treatment, leaf heat damages were determined as 0, 25, 50 and 75% and plants with different leaf heat damages were moved to a glasshouse (30–32/22–24 °C in day/night). The growth and developmental parameters were investigated until 70 days. ‘NB’ was significantly affected by leaf heat damages only in fruit yield while ‘CY’ was in fruit set, number and yield. ‘NB’ showed fast recovery after heat stress compared to ‘CY’. These results suggest that constant photosynthetic rate via increased transpiration rate as well as high proline content in heat stress condition confer faster recovery from heat damage of heat-tolerant cultivars in seedlings stages.
