Growth, Feed Utilization and Blood Metabolic Responses to Different Amylose-amylopectin Ratio Fed Diets in Tilapia (Oreochromis niloticus)

A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amylopectin ratios. Five isonitrogenous and isolipidic diets containing an equal starch level with different amylose-amylopectin ratios of 0.11 (diet 1), 0.24 (diet 2), 0.47 (diet 3), 0.76 (diet 4) an...

Effect of Diets with Different Forage to Concentrate Ratio for Fattening of Lohi Lambs

The objective of this study was to determine the effect of different forage to concentrate ratios for fattening of Lohi lambs. For this purpose, 75 lambs were randomly divided into 3 groups A, B and C, with 25 lambs in each group. Berseem fodder was supplemented with concentrate at different ratios (forage to concentrate) as 75:25, 50:50 and 25:75 and fed to groups A, B and C, respectively for ...

The Optimum Energy Density in Diets for Lori-Bakhtiari Lambs during a Fattening Program

Forty growing ram lambs (Lori-Bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in Iran. The feed intake (FI), body weight (BW), gain to feed ratio (G:F) and carcass characteristics were studied. Four treatments differed in metabolizable energy content (ME) as follow; 2, 2.3, 2.6 and 2.9 Mcal/kg for...

Energy efficiency of growing ram lambs fed concentrate-based diets with different roughage sources.

Poor-quality roughages are widely used as fiber sources in concentrate-based diets for ruminants. Because roughage quality is associated with the efficiency of energy use in forage-based diets, the objective of this study was to determine whether differing the roughage source in concentrate-based diets could change the energy requirements of growing lambs. Eighty-four 1/2 Dorper × 1/2 Santa Inê...

Metabolic response of the gastrointestinal tract of turkeys to diets with different levels of mannan-oligosaccharide.

Different levels of dietary mannan-oligosaccharide (MOS) administered for 16 wk to commercial male turkeys were evaluated for their efficacy on performance and on microbial activity in the digestive tract. The following levels of MOS were used in a diet: low (0.1% during the entire study), medium (0.4 and 0.2% in the first and second 8-wk periods, respectively), and high (1.0 and 0.4% in the fi...
