A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...

AIM To study the impact of deficiency of second line limiting amino acids (SLAA; valine, isoleucine and tryptophan) on the production performance and carcass characteristics of commercial broilers. MATERIALS AND METHODS A control (T1) corn-soy diet was formulated to contain all essential AA on standardized ileal digestible basis; While in T2-a 'moderate SLAA deficit' diet was formulated by re...

The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...

In this study, the effect of short-terms starvation (0, 2, 4 and 8 days) on plasma cortisol, glucose, triglyceride and cholesterol levels and also hepatosomatic index in Siberian sturgeon, Acipenser baerii, was investigated. After acclimation to experimental conditions for 10 days using formulated diet, 180 juvenile Siberian sturgeons (mean weight ? S.E.=19.3?0.4, n=15) were randomly distribute...

Two hundred sixteen prepubertal Genex Manor hybrid F1 gilts were used to determine the impact of lean growth rate on sexual development of gilts. This study was composed of two experiments (Exp. 1 and Exp. 2). In Exp. 1, at approximately 96 d of age and 54 kg weight, gilts were allocated with respect to growth rate and litter origin to one of two dietary treatments: 1) a diet formulated to maxi...

The AIN-93 rodent diets were formulated to substitute for the previous version (AIN-76A) and to improve the performance of animals that consume them. They are called AIN-93G, formulated for growth, and AIN-93M, for maintenance. Major changes included substituting cornstarch for sucrose and soybean oil for corn oil and increasing the amount in order to supply both essential fatty acids (linoleic...

To assess the possibility of using a formulated diet instead an iced trash fish for feeding spotted mandarin (Siniperca scherzeri), 20-week trial was conducted. The objective study to examine effects (FG) and (XG) on growth performance muscle nutrient composition fish. results showed that fed with XG had slightly higher survival rates, weight gain rate, fullness, hepatic index, viscera index co...

Little scientific information is available that has evaluated safflower (Carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. The objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (TMRs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. Two consecutive trials were conducted us...
