Food producing animals can be reservoirs of Campylobacter, a leading bacterial cause of human foodborne illness. Campylobacter spp. utilize amino acids as major carbon and energy substrates, a process that can be inhibited by thymol and diphenyliodonium chloride (DIC). To determine the effect of these potential additives on feed intake, live weight gain, and gut Campylobacter levels, growing p...

The objective of this research was to evaluate the effects of residual feed intake (RFI) determined under ad libitum feeding conditions on DMI and performance of yearling ewes fed either chopped or pelleted alfalfa hay. In Exp. 1, 45 ewe-lambs had ad libitum access to a pelleted grower diet for 63 d and individual DMI was determined using an electronic feed delivery system. Residual feed intake...

The present study was conducted to investigate the effect of xylo-oligosaccharide and xylanase supplementation on growth performance, carcass characteristics, nutrient digestibility, intestinal histology broilers. Six hundred day-old chicks (ROSS-308) were divided into four experimental groups (i.e. T1, T2, T3, T4). Each unit had six replicates 25 chicks/replicate. Following treatments offered:...

The high cost of feed has been the major hindrance to a growth, sustainability, profitability, and expansion poultry production. Black soldier fly larva (BSFL) meal is one most promising alternative protein sources widely accepted globally. This study evaluated growth performance improved indigenous chicken (IIC)-fed diets containing different inclusion levels BSFL meals. rates included 0% (Die...

The growth-promoting effects of two dietary acidifiers based on formic acid were studied with 320 fattening pigs from ca 2 kg to ca 05 kg of body weight. The sorbate-coated formic acid contained formic acid and ammonium formate which were absorbed in diatomaceous earth and coated with potassium sorbate. The investigated liquid blend contained formic and lactic acids as the major components. The...

A completely randomised design experiment was conducted to determine if grouphoused grower-finisher pigs (43.9 to 95 kg) show differences in performance and nitrogen utilisation when provided with a single high lysine diet (11 g/kg) or with a mean lysine concentration of 9.5 g/kg, either as a single diet or as a series of two or four diets. Four hundred and forty pigs were assigned to four diet...

Two trials were conducted to study the effect of inclusion of hull-less barley and exogenous enzyme to broiler diet on the growth performance, apparent metabolisable energy (AME) and Nutrient digestibility of broiler chickens. The experiments were 3×4 factorial arrangements with three levels of enzyme (0, 300 and 600 g/ton) and four levels of hull-less barley inclusion (0, 10, 20 and 30%) in di...

This study examined whether pre-treating palm kernel expeller (PKE) with exogenous enzyme would degrade its fiber content; thus improving its metabolizable energy (ME), growth performance, villus height and digesta viscosity in broiler chickens fed diets containing PKE. Our results showed that enzyme treatment decreased (p<0.05) hemicellulose and cellulose contents of PKE by 26.26 and 32.62%, r...
