Turkish Journal of Veterinary & Animal Sciences
In this study, the effect of ellagic acid on the performance, egg quality, digestibility, cecal microflora, serum malondialdehyde (MDA) level, and biochemical parameters in quails reared under normal conditions and at high environmental temperatures was investigated. The animals (n = 240; 5-weeks old) reared at 2 environmental temperatures [thermoneutral (TN) and heat stress (HS)] and in 4 diet groups containing different ellagic acid doses (0, 100, 200, and 400 mg/kg) were randomly assigned to 8 groups according to the 2 × 4 factorial design. Feed intake, egg weight, and egg production were higher (P < 0.001) and feed conversion (P < 0.01) was better in the TN groups compared to the HS groups. Egg (P < 0.01) and shell weights (P < 0.001) were higher in the TN groups compared to the HS groups. The effect of ellagic acid supplementation on shell weight was statistically significant in the TN and HS groups (P < 0.05). The effects of environmental temperature and the supplementation of ellagic acid on digestibility of dry matter (P < 0.05), ether extract (P < 0.01), and crude protein (P < 0.01) were statistically significant in the TN and HS groups. Supplementation of ellagic acid reduced the total coliform bacteria count (P < 0.01) and increased the total lactic acid bacteria count (P < 0.001) in the cecum. Serum MDA levels increased with heat stress (P < 0.001) and decreased with the supplementation of ellagic acid (P < 0.001). The effect of environmental temperature on serum glucose (P < 0.001), cholesterol (P < 0.05), total protein (P < 0.05), alanine aminotransferase (ALT) (P < 0.001), sodium (P < 0.05), and magnesium was significant. In conclusion, the supplementation of ellagic acid decreased oxidative stress and total coliform bacteria count and improved the feed conversion and egg quality in quails under heat stress. Moreover, ellagic acid increased the digestibility of nutrients and had a positive effect on lactic acid bacteria. It was observed in this study that these beneficial effects of ellagic acid increased with an increasing dose, and 400 mg/kg was the most effective dose.

Feeding Dynamics And Performance Of Beetal Does In Relation To Body Condition Score At The Time Of Mating, Arpan Sharma, Sandeep Kaswan, S. Siva Kumar, Jaspal Singh Lamba
Turkish Journal of Veterinary & Animal Sciences
The body condition of does at the time of mating may affect feeding patterns and production performance during forthcoming lactation. For investigation, 40 Beetal does available for breeding were utilized, and their body condition score (BCS) was estimated using the visual-cum-palpation method with a 9-point scale (scale of 1=5 with increments of 0.5 point). The available goats were divided into 3 groups: higher BCS (T$_{≥3.0}$; n =11), moderate BCS (T$_{2.5}$; n = 8), and lower BCS (T$_{≤2.0}$; n = 21) and maintained in 2 random groups (20 each). Beetal goats with higher BCS at breeding time spent significantly (P < 0.01) more time feeding comfortably and less time feeding with difficulty than moderate and lower BCS goats. T2.5 and T$_{≤2.0}$ goats struggled (displacement and pushing) more at feeders, which included T$_{≤2.0}$ goats eating from the ground for more time (P < 0.01) than the other groups. T$_{≥3.0}$ goats had more agonistic interactions (threatening and hitting) toward moderate and lower BCS goats at feeders. Goats with higher BCS at mating had significantly (P < 0.05) higher milk yield during subsequent lactation; however, the composition of the milk did not differ among the groups. Mean disease incidence rate and number of days of disease per goat were significantly (P < 0.01) lesser in the T$_{≥3.0}$ group than other groups. It was concluded that Beetal goats should not have less than 3.0 BCS at the time of mating for better performance and health status.

The effects of in ovo administration of β-hydroxy-β-methylbutyrate (HMB) on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative (no injection) and positive (physiologic serum injection) controls and three HMB treatment groups. HMB solution was injected at 0.1% (Group 1), 0.2% (Group 2), and 0.3% (Group 3) concentrations. There were no significant differences between the groups for live weight gain, feed conversion rate, and hot carcass, breast meat, liver, and heart weight. However, the gizzard weight in Group 1 was significantly higher than those in the other groups (P < 0.05). Although the intestinal villi lengths in the treatment Groups 1 and 3 on day 20 were greater than those in the control groups (P < 0.01), at the end of the experiment there were no significant differences among the groups. For antibody levels, the differences between groups on days 4 and 42 were highly significant (P < 0.01), and the antibody levels in Group 2 were higher than those in the other groups. Separately, growth performance and antibody levels were positively correlated with the length of villi in Group 2 (HMB 0.2%).

Turkish Journal of Veterinary & Animal Sciences
Dietary supplementation effects of 0%, 0.25%, 0.5%, and 1% glutamine were investigated on the performance and development of the gastrointestinal tract in broilers reared under hot conditions. No significant differences were observed between the treatments for feed intake and feed conversion ratio during the starter period, grower period, or entire experiment (P > 0.05). During the grower period, only 0.5% glutamine-fed birds had higher body weight gain than others (P < 0.05). For the entire period, body weight gain of 0.5% glutamine-fed birds was greater than that of 0.00% and 0.25% glutamine-fed ones (P < 0.05). Furthermore, 0.5% glutamine-fed birds showed longer villus height than other birds (P < 0.05). In the jejunum, both 0.5% and 1% glutamine consumption caused longer villus height as compared to 0.00% and 0.25% glutamine (P < 0.05). Villus height of 0.25% glutamine-fed birds was higher than that of 0.00% glutamine-fed ones (P < 0.05). None of the ileum morphological parameters were affected by glutamine supplementation (P > 0.05). In conclusion, supplementation of 0.5% glutamine improved the intestinal morphology and body weight gain of broilers under heat stress. Higher dietary glutamine (1%) increased the villus height in the jejunum …

The effects of 3 levels of commercial Aspergillus meal prebiotic (Fermacto®) in broiler diets with 2 levels of dietary crude protein (CP) on the growth performance, carcass characteristics, apparent ileal digestibility of CP and organic matter (OM), and serum lipid profile were evaluated using 240-day-old broiler chickens as a factorial arrangement in a completely randomized design. From the grower period, 3 groups received normal diets formulated to meet Ross-308 CP and other nutrient requirements with 3 levels of Fermacto®. The other 3 groups received experimental diets with 2% less CP, with the same levels of Fermacto®. None of the growth …

Twenty worm-free male West African dwarf (WAD) goats, 7-8 months of age, were used to study the effect of dietary protein on their response to mixed infections of trychostrongyles. The goats were divided into 4 groups (A-D), each containing 5 animals. Groups A and B were fed forages with concentrate feed containing 17.06% crude protein, whereas Groups C and D were fed forages alone. An escalating infection of 500 infective larvae (L3), 1000 L3, 2000 L3, and 4000 L3 was given consecutively at weeks 0, 1, 2, and 3, respectively, for 4 weeks to groups A and D. Patency and …

Economic Selection Index Using Different Milk Production Traits Of Holstein And Its Crossbreds, Md. Kabirul Islam Khan, Jewel Mazumder
Turkish Journal of Veterinary & Animal Sciences
The study was conducted to estimate the Best Linear Unbiased Prediction (BLUP) breeding values of different milk production traits for Holstein and its crossbreds and to construct an economic selection index or total merit for individual cows from 2 different dairy farms in Chittagong, Bangladesh. The BLUP-estimated breeding values were obtained by AIREML, and an economic selection index was constructed as the sum of the product of the estimated breeding value with the economic value for each trait (lactation milk yield, calving interval, and liveweight). The Holstein × Sahiwal crossbred showed better phenotypic performance in both farms while the same …
