Copper is a unique mineral, When it is added to pig diets at a high level (much higher than the nutritional requirement), copper stimulates growth and feed efficiency much like antibiotics do. This effect is particularly evident with young pigs. Table 1 shows results of UK studies over a 1 &year period in which high copper diets were fed to weanling pigs (from 17 to 40 lb). Copper increased gro...

A total number of 540, one day old of commercial broiler chicks were used to study the effect of selenium (Se) and cadmium (Cd) separately and in mixture on broiler chicks' performance (from one day to 49 days of age). Birds were distributed randomly into 18 dietary treatments groups, each groups represented by triplicate pens (10 chicks each) until the end of the experiment (49 days of age). T...

Challenge tests are a clear opportunity for manufacturers interested in the evaluation of their management system with the aim to reduce the spread of foodborne pathogens. This is a main concern especially in ready-to-eat food in relation to the risk associated with Listeria monocytogenes. For small and medium-scale food industry the manufacturing practices and products formulation are characte...

objective(s) the process of wound healing involves tightly integrated events including inflammation, granulation tissue formation and remodeling. systemic administration of l-arginine promotes wound healing but its global side effects are undesirable. to confine the action of l-arginine at the site of injury, we tested the effects of local administration of l-arginine on the healing of excision...

BACKGROUND Conventional vaccination programs using a single injection of a combined vaccine against porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae (MHYO) can promote a strong immune response that reduces feed intake for 24 to 48 h post injection. Often such vaccines are given around the time of weaning during a critical stress period in which feed intake is already compromised. S...

The objectives of this paper were production of probiotic yoghurt using L. paracasei ssp. tolerans, and evaluation of pH changes, viable counts, and organoleptic properties of the produced yoghurt. It was observed that the pH decrease during the fermentation period was faster in the milk inoculated with L. paracasei ssp. tolerans plus starter culture. There was a gradual decrease in pH in both ...

Undefined mesophilic mixed (DL-type) starter cultures are composed of predominantly Lactococcus lactis subspecies and 1-10% Leuconostoc spp. The composition of the Leuconostoc population in the starter culture ultimately affects the characteristics and the quality of the final product. The scientific basis for the taxonomy of dairy relevant leuconostocs can be traced back 50 years, and no docum...

The effect of including hydrolyzed porcine mucosa sprayed into soybean meal (HPM) in the diet was studied in broilers. In experiment 1 (pen study), 1,080 one-day-old chicks were used in a completely randomized design with 8 treatments arranged as a 4 × 2 factorial with 4 levels of HPM (0, 2.5, 5.0, and 7.5%) and 2 levels of Lys (1.23 and 1.38%). From d 1 to 22, HPM inclusion quadratically impro...
