“…The resulting higher concentrations of serum calcium and phosphorus that were observed suggested that a GABA-producer could regulate the utilization of dietary calcium and phosphorus thereby alleviating defected egg caused heat-stress. Mashaly et al (2004) and Al-Harthi (2014) noted that high ambient temperature has a detrimental effect on laying performance, feed intake and feed conversion efficiency. Therefore, such high ambient temperature might cause a decline in activity of digestive enzymes (e.g.…”

“…In addition, heat-stress also affects growth rate, metabolism, immunity and reproduction of animals with an immeasurable impact ( Attia et al, 2011 ; Bloemhof et al, 2012 ; Nesamvuni et al, 2012 ). Although remarkable advances of feeding animals under high-density conditions have been widely applied ( Attia et al, 2006 ; Al-Harthi, 2014 ), heat-stress remains a costly issue for the animal production, especially for poultry as they lack sweat glands. Therefore, alleviating heat-stress is necessary for ensuring animal production in hot environments.…”

Heat-stress remains a costly issue for animal production, especially for poultry as they lack sweat glands, and alleviating heat-stress is necessary for ensuring animal production in hot environment. A high γ-aminobutyric acid (GABA)-producer Lactobacillus strain was used to investigate the effect of dietary GABA-producer on laying performance and egg quality in heat-stressed Hy-line brown hens. Hy-Line brown hens (n = 1,164) at 280 days of age were randomly divided into 4 groups based on the amount of freeze-dried GABA-producer added to the basal diet as follows: i) 0 mg/kg, ii) 25 mg/kg, iii) 50 mg/kg, and iv) 100 mg/kg. All hens were subjected to heat-stress treatment through maintaining the temperature and the relative humidity at 28.83±3.85°C and 37% to 53.9%, respectively. During the experiment, laying rate, egg weight and feed intake of hens were recorded daily. At the 30th and 60th day after the start of the experiment, biochemical parameters, enzyme activity and immune activity in serum were measured. Egg production, average egg weight, average daily feed intake, feed conversion ratio and percentage of speckled egg, soft shell egg and misshaped egg were significantly improved (p<0.05) by the increasing supplementation of the dietary GABA-producer. Shape index, eggshell thickness, strength and weight were increased linearly with increasing GABA-producer supplementation. The level of calcium, phosphorus, glucose, total protein and albumin in serum of the hens fed GABA-producing strain supplemented diet was significantly higher (p<0.05) than that of the hens fed the basal diet, whereas cholesterol level was decreased. Compared with the basal diet, GABA-producer strain supplementation increased serum level of glutathione peroxidase (p = 0.009) and superoxide dismutase. In conclusion, GABA-producer played an important role in alleviating heat-stress, the isolated GABA-producer strain might be a potential natural and safe probiotic to use to improve laying performance and egg quality in heat-stressed hens.

“…Bioactive compound in those extracts were suspected playing important role to decrease heat stress impact. The most compounds in those extracts were as antioxidant (Al-Harthi 2014). Result of studies showed that there were several bioactive compounds played role as antioxidant in extract of S. tetrasperma (Kahkonen et al 1999;Khayyal et al 2005;El-Wakil et al 2015), turmeric rhizome (Gupta et al 2010;Mohana & Fadma 2014), and neem leaf .…”

ABSTRAKSugito, Hambal M, Isa M, Nurliana, Delima M. 2015. Pemberian ekstrak Salix tertrasperma kombinasi dengan ekstrak kunyit dan mimba untuk peningkatan kualitas telur ayam yang dipelihara pada suasana stres panas. JITV 20(3): [193][194][195][196][197][198][199]. DOI: http://dx.doi.org/10. 14334/jitv.v20i3.1186 Kualitas telur akan menurun apabila ayam mengalami stres panas. Pemberian beberapa jenis ekstrak tanaman dilaporkan dapat mengurangi dampak tersebut. Tujuan penelitian ini adalah untuk mengetahui efek pemberian ekstrak Salix tetrasperma dikombinasikan dengan ekstrak kunyit dan mimba untuk meningkatkan kualitas dan produktivitas ayam petelur dalam kondisi stres panas. Penelitian ini menggunakan 60 ekor ayam petelur strain Isa Brown periode layer berumur 6 bulan. Pemeliharaan dilakukan pada kandang kawat individu. Pemberian pakan dan minum secara ad libitum. Pelaksanaan penelitian menggunakan metode rancangan acak lengkap dengan 5 perlakuan dan masing-masing perlakuan terdiri atas 12 ulangan. Sebagai kontrol negatif tanpa diberi suplemen antistres (KN) dan kontrol positif diberi suplemen antistres komersil (KP). Formulasi dosis ekstrak yang diberikan adalah S. tetrasperma 1.000 mg/l air minum (EJ), S. tetrasperma 1.000 mg/l + kunyit 250 mg/l + mimba 250 mg/l (EJ+K1), dan S. tetrasperma 1.000 mg/l + kunyit 500 mg/l + mimba 500 mg/l air minum (EJ+K2). Ayam dipelihara dalam suasana stres panas selama 5 jam perhari pada kisaran suhu 34,0 ± 1,5°C. Pemberian suplemen dilakukan dengan cara dilarutkan dalam air minum dan diberikan selama 30 hari pada pagi sampai siang hari. Hasil penelitian menunjukkan bahwa pemberian ekstrak S. tetrasperma secara tunggal ataupun dikombinasi dengan ekstrak kunyit dan mimba mempengaruhi (P<0,05) tebal kerabang telur, tetapi tidak mempengaruhi warna kuning telur, tinggi albumin, berat telur, dan nilai Haugh Unit (HU). Pemberian ekstrak S. tetrasperma 1.000 mg/l air minum dapat digunakan untuk meningkatkan kualitas telur pada ayam yang menderita stres panas. Quality of eggs might decrease when hens under heat stress. A further study found that a specific plant extracts could reduce the impacts of heat stress. The aim of this study was to determine effects of Salix tetrasperma plant extract in combination with extract of turmeric and neem to improve egg quality and productivity of laying hens under heat stress. Sixty laying hens strain Isa Brown of 6 months old were used and reared in individual cages. The feed and drinking water were supplied ad libitum. This study was conducted in a completely randomized design with five treatments (two controls and three treatments) and each treatment consisted of 12 replication. Treatment consisted of with (KP) and without (KP) commercial anti-stress supplement. Formulations of extract were S. tetrasperma 1.000 mg / l water (EJ), S. tetrasperma 1.000 mg / l + Turmeric 250 mg / l + neem 250 mg / l (EJ+K1), and S. tetrasperma 1.000 mg / l + Turmeric 500 mg / l + neem 500 mg / l drinking water (EJ+K2). The hens were exposed to heat stress for 5 h...

“…The increasing consumption of healthy biological products requires investigation regarding the possibility of manipulating products of animal origin through dietary strategies. Increased carotenoid content is beneficial for human health, because carotenoids can be antioxidant and decreasing yolk cholesterol concentration (Al‐Harthi, ; Park, Upadhaya, & Kim, ; Zahroojian, Moravej, & Shivazad, ). Studies conducted by Zahroojian et al () suggested that use of 2.0% to 2.5% Spirulina in diets of laying hens over 60 days provided an aesthetically pleasing gem color without causing negative effects on performance.…”

The aim of this study was to investigate whether microalgae in Japanese quail feed alters performance, fatty acid profiles in the eggs and egg quality. One hundred quails were distributed in four groups and five replicates of five birds per experimental group. The treatments consisted of four levels of Spirulina platensis microalgae (0%, 5%, 10%, and 15%) in the diets. We evaluated the productive performance and chemical‐physical characteristics of eggs, the oxidant/antioxidant status in egg yolks, and the fatty acid profile in the diet and egg yolks. Microalgae in the diet did not influence egg production; however, it increased the yolk index as well as the color intensity of the yolk. Saturated and polyunsaturated fatty acid levels decreased in egg yolks, and monounsaturated fatty acid levels increased in the yolks. Lipid peroxidation levels were lower and total antioxidant capacity was higher in egg yolks of quails receiving microalgae in the diet. Practical applications Microalgae in quail diets improves egg quality and provides benefits to consumer health, acting as an antioxidant and immune‐stimulant. Microalgae in quail diets had positive effects on egg quality. This is because it reduced levels of saturated fatty acids that are undesirable, and increased monounsaturated fatty acid levels that are beneficial to the health of consumers. Finally, antioxidants increased in egg yolks, consequently reducing lipid peroxidation.
