Two experiments were conducted with male broilers to 1) establish a methodology for predicting effective caloric value (ECV), defined as dietary caloric density (CD) necessary for broilers to achieve specific BW and feed conversion ratio (FCR) combinations under standardized conditions and 2) quantify the ECV attributable to pellet quality (PQ), defined as the pellet to pellet fines ratio in th...
The purpose of this study was to investigate the hypothesis that dietary supplementation with glutamic acid has beneficial effects on growth performance, antioxidant system, intestinal morphology, serum amino acid profile and the gene expression of intestinal amino acid transporters in growing swine fed mold-contaminated feed. Fifteen pigs (Landrace×Large White) with a mean body weight (BW) of ...
This study was conducted to assess the effect of dietary use of a clinoptilolite-rich tuff (Cp) on health status and performance of weaned, growing and finishing pigs and its compatibility during simultaneous oral administration of antimicrobials (AM) such as enrofloxacin (E) or salinomycin (S). Weaners (720) were assigned in 2 experimental groups and 4 subgroups based on the inclusion or not o...
Net feed intake (NFI) is a moderately heritable feed efficiency trait that has been shown to be genetically independent of ADG and BW in beef cattle. Objectives of this study were to characterize NFI in growing bulls, and to examine phenotypic correlations between NFI and performance, body composition, and fertility traits. Net feed intake was positively correlated phenotypically with feed conv...
AIM This study was carried out to evaluate groundnut haulms (GNH) as alternate feed source by its incorporation and assessment in terms of feed intake and growth performance in the diets of broilers. MATERIALS AND METHODS A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates (n=60). Experimental Birds in group T1 were fed...
A meta-analysis on the effects of management and animal-based factors on the performance and feed efficiency of growing pigs can provide information on single factor and interaction effects absent in individual studies. This study analysed the effects of such factors on average daily gain (ADG), feed intake (FI) and feed conversion ratio (FCR) of grower and finisher pigs. The multivariate model...
The aim of this study was to determine the effect of anthocyanin from roselle (Hibiscus sabdariffa) supplemented diets on growth, survival and body composition of rainbow trout (Oncorhynchus mykiss) for 60 days. Fish were fed 0 % (control), 0.5 %, 1 % and 2 % anthocyanin extract in complete random design. Fifteen fish with the same initial weight (14 ± 0. 1 g) were selected and randomly distr...
in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...
An experiment was conducted to assess the optimum nutrient requirement and ideal mating ratios for Alabio ducks for production of fertile eggs and hatchability under rural feeding management. A total of 135 forty weeks old females and 27 males were used in the study. They were fed on low (17.5%), medium (19.5%) and high (21.5%) crude protein (CP) in diets containing approximately 3050 kcal of m...
Using probiotics can control pathogens by a variety of mechanisms. Probiotics can promote growth performance and have, therefore, become increasingly important in the aquaculture industry. Convict Cichlid belongs to the family of Cichlidae and is known for its rapid development in laboratory conditions and is suitable for behavioral examinations. The aim of this study was to evaluate the effect...
