Ginkgo Biloba Extract Egb761 Improved Anti-Heat Stress Responses In Chickens In Vivo Via Regulation Of Heat-Shock Protein Expression And Distribution, Xiaohui Zhang, Miao Zhang, Endong Bao

Turkish Journal of Veterinary & Animal Sciences

Heat stress is a lethal threat to chickens. This study investigated the protective effect of a Ginkgo biloba extract EGB761 against heat stress in chickens in vivo. A total of 200 one-day-old hens were separated randomly into control (Con), heat stress (HS), 0.1% EGB administration and heat stress (0.1% EGB+HS), 0.3% EGB administration and heat stress (0.3% EGB+HS), and 0.6% EGB administration and heat stress (0.6% EGB+HS) groups. After EGB761 administration for 45 days, ten chickens were selected randomly, assigned to one of the designated groups, and exposed to a one-time heat stress condition of 38 ± 1 °C for …

For the trial, 54 Bovans White laying hens were used at 95 weeks of age and were housed in groups of three birds per cage. A completely randomized design was used with a factorial scheme of treatments 2 × 3 (rations with two energy densities × three thermal environments). Corn-soybean meal based diets with similar composition, differing only in energy levels, were obtained with soybean oil inclusion (2750 kcal and 3250 kcal metabolizable energy (ME)). Climate-controlled rooms were used to mimic a thermoneutral environment (TE) (average temperature of 24.3 °C and relative humidity of 62.3%), a hot environment (HE) (average …

Turkish Journal of Veterinary & Animal Sciences

The present study was designed with an objective to evaluate the impact of various strategies to alleviate heat stress on certain physiological attributes viz. respiratory rate (RT), body surface temperature (BST), pulse rate (PR), and respiratory rate (RR); biochemical attributes viz. glucose, total protein (TP), and cholesterol; and endocrinological parameters (tri-iodothyronine and tetraiodothyronine) of the Nili-Ravi buffaloes during early summer season. Lactating Nili-Ravi buffaloes (n = 20) with close production and parity stage were divided into four treatment groups as group A (control group under roof shades only), B (experimental group under roof shades with antistress supplementation), C (experimental group …


The Effect Of Year, Month, Region, And Herd Size On Bulk Tank Somatic Cell And Standardplate Count, And The Determination Of Optimum Herd Size In The Intensive Holsteinfriesian Dairy Farms In The Turkish Republic Of Cyprus, Hati̇ce Di̇lek Arsoy Jan 2020

The Effect Of Year, Month, Region, And Herd Size On Bulk Tank Somatic Cell And Standardplate Count, And The Determination Of Optimum Herd Size In The Intensive Holsteinfriesian Dairy Farms In The Turkish Republic Of Cyprus, Hati̇ce Di̇lek Arsoy

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to determine the effects of mount, year, region, and herd size on the bulk tank somatic cell count (SCC) and standard plate count (SPC) and total milk production of Holstein Friesian cows and to decide for optimum herd size in Northern Cyprus. The total number of cattle was 64,450 heads and the number of enterprises was 168 in 2016. The milk samples were collected once or twice a month from each herd. SCC and SPC were determined with the Fluoro-opto-electronic counter method. Herd sizes were described from small to extra-large enterprises for Northern Cyprus …


The Influence Of Vitamin C And Early-Age Thermal Conditioning On The Quality Of Meat And Specific Production Characteristics Of Broilers During Heat Stress, Zoran Ruzic, Zdenko Kanacki, Marija Jokanovic, Suzana Vidakovic, Slobodan Knezevic, Slavoljub Jovic, Smiljana Paras Jan 2020

Turkish Journal of Veterinary & Animal Sciences

Heat stress (HS) is one of the greatest problems in contemporary chicken production and it entails significant economic losses. The purpose of this paper is to examine the influence of early-age thermal conditioning (ETC), vitamin C (Vit C) supplementation, and their combination on the production characteristics and specific quality parameters of the meat of broilers which were exposed to chronic HS in the last two weeks of breeding. Four hundred broilers (Cobb 500) of both sexes were divided into 4 experimental groups. Group C was given Vit C (2 g/L) dissolved in water from day 22 until the end of …


Nutrient Digestibility, Performance, And Egg Quality Traits Of Quails Raised In Different Stocking Densities And Ascorbic Acid Supplementation In A Hot, Tropical Environment, Adi Ratriyanto, Firmanda Firmanda, Heni Purwanti, Murjoko Murjoko Jan 2020

Nutrient Digestibility, Performance, And Egg Quality Traits Of Quails Raised In Different Stocking Densities And Ascorbic Acid Supplementation In A Hot, Tropical Environment, Adi Ratriyanto, Firmanda Firmanda, Heni Purwanti, Murjoko Murjoko

Turkish Journal of Veterinary & Animal Sciences

This study investigated the effects of stocking density (SD) and ascorbic acid (AA) supplementation on nutrient digestibility and laying performance of quails in a tropical environment. Four hundred and eight Japanese quails were designated in a 3 × 2 factorial arrangement with four replicates. The birds were distributed to three SDs, namely 40 (SD-1), 45 (SD-2), and 50 birds per m2 (SD-3) by allotting 15, 17, and 19 birds per cage, respectively (cage size: 3750 cm2). Each SD was supplemented with AA (0 and 250 mg/kg). Interaction was identified between SD and AA on egg production (P < 0.01), while the highest value was yielded in SD-2 supplemented with AA (83.6%). SD-3 achieved lower ether extract (EE) and crude fiber (CF) digestibility (P < 0.05) and eggshell thickness (P = 0.01) than SD-1 or SD-2. AA supplementation enhanced dry matter (DM), EE, CF, crude ash (CA), and calcium (Ca) digestibility (P < 0.05). AA improved egg weight, feed conversion, and protein and energy efficiency ratios as well as eggshell weight and thickness (P < 0.05). The SD of 45 birds per m2, combined with AA supplementation at 250 mg/kg, can be recommended for quails housed in hightemperature environments.
