Animals generally adjust their behavior in response to bodily state (e.g. size and energy reserves) to optimize energy intake in relation to mortality risk, weighing predation probability against starvation. Here we investigated whether brown trout adjust their behavior in relation to feeding history (energetic status) and body size during a major early-life selection bottleneck, when fast grow...
AIM This study was conducted to assess the effect of feeding paddy straw plus nonforage fiber sources based complete rations with different levels of neutral detergent fiber (NDF) on hemato-biochemical and mineral parameters of lactating dairy cows. MATERIALS AND METHODS The study was conducted for 6 months in 18 lactating dairy cows, divided into three groups of six each, by feeding them on ...
Responses to sugars in dry or liquid formvary from study to study. When fed in proper amounts, sugars should not depress ruminalpH, and there is some evidence that they actuallyhelp toprevent a drop in pH after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. Adding sugars doesprioritize the need for rumen degraded protein (RDP).we all know, sugars...

This study was designed to investigate the effects of different levels of Tarragon powder on performance and carcass’ characteristics of broiler chickens. 200 one-day-old Ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. Experimental diets were set on the basis of corn-soy-wheat and Ross 30...

Supplementary irrigation moderates the damage caused by drought stress in rainfed agriculture. Meanwhile, the application of nano fertilizers and methanol as the foliar application can be considered as effective management strategies to improve production under dryland conditions. For this purpose, the effect of supplementary irrigation, nano fertilizer spraying, and methanol foliar spraying wa...
One hundred ninety-two steers were fed cottonseed meal, soybean meal or urea supplemented rations in which the corn grain was fed whole (with 5 percent corn silage) or in the high moisture or steam flaked form (with 14 percent corn silage dry matter added). Rates of gain and feed efficiencies were approximately equal for steers fed soybean meal and cottonseed meal and slightly superior to those...
The study was conducted to determine the effect of dietary energy on milk yield and its composition under the influence of bovine somatotropic (bST) hormone in Nili Ravi buffaloes. Multiparous buffaloes (n=12) at mid lactation and similar level of production were selected and randomly divided into three groups (A, B and C) with four animals in each group in a completely randomized design. All t...
In a small, 12 ha, mesotropic lake, roach Rutilus rutilus performed diel habitat shifts that clearly influenced the composition of their diet. During daytime, roach stayed in the littoral zone and concentrated on littoral prey. At night they were found in the pelagic zone, and pelagic prey items such as Daphnia spp. or Chaoborus flavicans dominated their food. On a seasonal scale, there were sh...
