Porcine reproductive and respiratory syndrome (PRRS) and porcine epidemic diarrhea (PED) are two diseases costly to the U.S. swine industry. The objective of this study was to determine the impact of PRRS virus and PED virus, alone or in combination, on growth performance, feed efficiency, and digestibility in grower pigs. Forty-two gilts (16 ± 0.98 kg BW) naïve for PRRS and PED were selected a...

The aim of this study was to evaluate the effects of fibre level and source in the diet on the digestive physiology, growth performance and carcass traits of different genotypes of pig, and the efficiency of supplementation of an exogenous enzyme mixture to fibrous diets for weaned piglets. The first experiment showed that the coefficient of total tract apparent digestibility (CTTAD) of nutrien...

Two experiments were conducted to evaluate the nutritional quality of 2 varieties of Purdue high-digestible sorghum (PHD1 and PHD2) and a normal sorghum, compared with corn, in diets of pigs and broiler chicks. In Exp. 1, 12 pigs (average BW, 55 kg) fitted with ileal T-cannula were fed 4 diets containing 946 g of corn or sorghum (PHD1, PHD2, and normal) per kg in a 2-period crossover design (i....

A semi-field study was carried out to evaluate the effect of two medicinal herbs, individually and in combination, on growth performance, carcass traits, nutrient digestibility and immune response of broiler chickens.  A total of 384 one-day-old straight-run Arbor Acres broiler chickens were allocated into 24 floor pens prepared in a commercial broiler house. Pen-groups were fed one of the foll...

This study was conducted to investigate the effects of exogenous enzymes on growth performance, ileal digestible energy (IDE) and apparent ileal digestibility of CP and amino acids (AA) in broiler chickens fed corn-soy diets formulated using 3 different sources of corn (corn 1, corn 2, and corn 3). One-day-old male broiler chicks (n = 3,600) were allocated to 15 dietary treatments as 5 treatmen...

BACKGROUND Use of prebiotics in companion animal nutrition is often considered advantageous over probiotics because of the ease of handling, ability to withstand processing and storage etc. While most of the studies on prebiotic use in dogs have been done with processed food as basal diet, the response in relation to homemade diet feeding is not very well explored. METHODS The study was condu...

A total of 420 day-old male Ross chicks were weighed at d 1 of life and assigned to test diets to assess the efficacy of a new Buttiauxella spp. phytase expressed in Trichoderma reesei. Diets were: positive control (PC) adequate in nutrients and negative control (NC) diet (40% and 17% less available phosphorous (P) and calcium (Ca), respectively) supplemented with 6 levels of phytase 0, 250, 50...

Processing remains of brown shrimp, Crangon crangon, account for up to 60 % the catch while only small muscle fraction is used human consumption. Incorporation into aquafeeds high-valued species would reduce waste, create by-product value and promote sustainable aquaculture development. A detailed chemical characterisation from mechanically peeled shrimp was made apparent nutrient digestibility...

A COMPLETE knowledge of the factors that contribute to the nutritive value of native grass and hay is of both practical and scientific value. Seasonal and environmental factors contribute largely to variations in the nutrient content of the grass, and other less well-defined factors apparently influence the availability of these nutrients in digestion. Factors associated with the physical chara...
