We evaluated the preferences of nursery pigs for diets containing increasing distillers dried grains with solubles (DDGS), varying in color, or high-protein distillers dried grains (HP-DDG) and the effects of flavor supplementation on pig preference and growth performance. In Exp. 1 through 5, diet preference was determined in weanling pigs adjusted to a commercial diet for at least 10 d, and t...

  This study was conducted to evaluate the efficacy of live food (Artemia urmiana) and commercial diet in rearing of Oncorhynchus mykiss larvae. Experiment started when larvae were 0.12g in weight. Triplicate groups of fish were offered one of four treatments: (1) a commercial starter food (2) live Artemia urmiana nauplii (for 3 days) (3) live Artemia urmiana nauplii (for 7 days) and (4) combin...

The objective of this study was to investigate the effect of dietary supplementation with microbially-fermented rice bran on growth performance in broiler chickens. A total of one hundred and twenty 1-day-old broiler chickens, were randomly assigned to 5 dietary treatments in cages of 4 chicks each; each treatment had 6 replicate cages. A basal diet, formulated to be adequate in energy and nutr...

The present study was conducted to evaluate the effects of physical form of starter and alfalfa hay (AH) provision on growth performance, ruminal fermentation, and blood metabolites of Holstein dairy calves. Forty-four 3d-old Holstein dairy calves with a mean starting BW of 39.9 ± 1.1 kg were used in a 2 × 2 factorial arrangement. The factors were dietary forage level (0 or 150 g kg-1</sup...

OBJECTIVE This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) corn-soybean diets. METHODS A total of 350 Youxian Sheldrakes (7d old) were randomly divided into 5 treatment groups...

The limiting sequence and relative ratio of lysine (Lys), methionine (Met), and threonine (Thr) for calves about 2 mo of age fed milk replacers (MR) containing soy protein are not clearly defined. The objective of the study was to investigate the effect of supplementing MR containing 22% CP, half from soy protein concentrate (SPC, 40.56% CP, flour) and half from whey proteins, with Lys, Met, an...

Two feeding trials with baby pigs were conducted to evaluate the effects of additions of L-tryptophan and L-giutamic acid to a low protein (16%) starter diet on performance and plasma urea nitrogen, a-amino nitrogen and free tryptophan. In experiment 1, but not in experiment 2, glutamic acid addition (3.36%) improved rate of gain and feed efficiency. Tryptophan addition did not improve performa...

This study was conducted to examine the influence of supplementation of sodium butyrate, sodium monensin or calcium propionate in a starter diet on the performance and selected plasma metabolites (plasma glucose, non-esterified fatty acids and β-hydroxybutyrate) of Holstein calves during pre- and post-weaning periods. Twenty-four newborn Holstein calves were housed in individual hutches until 1...

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...

in this research, we investigated the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, immune response and blood cholesterol in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and replicated 4 times with 12 chicks per pen in a completely randomize design experiment in 6 wk. diet ...
