ABSTRACT This study aimed to evaluate sweet potato feed as an alternative energy supplement for ovine. A latin-square design was used assess the effects of feeding animals 0, 0.5, 1 and 1.5% their body weight in well ryegrass hay (Lolium multiflorum) twice daily, mineral salt water ad libitum. During this 8 males were housed metabolic cages with urine feces collectors. Each round experimentatio...

The objective of this study was to evaluate the effect adding exogenous enzymes diet on nutrient intake and digestibility, nitrogen balance, ingestive behavior rumen movement ewe lambs. Five lambs, Dorper x Santa Inês crossbred, with an average age 7 ± 1 months, weight 36.40 2.36 kg were assigned in a 5x5 Latin square design. treatments consisted concentrate: Allzyme, Fibrozyme®, Amaize®, Mix C...

Effects of rice straw particle size and physically effective neutral detergent fiber (peNDF) on particle size distribution of different digestive tract, nitrogen (N) metabolism, blood biochemical parameters, microbial amino acid (AA) composition and intestinal AA digestibility in goats were investigated. A 4 × 4 Latin square design was employed using four mature Liuyang black goats fitted with ...

Holstein steers in metabolism stalls were utilized to determine apparent digestibility of N (DN), N retention (NR) expressed as a percentage of total N consumed, and Mcal/kg digestible energy (DE) when diets of seven different classes of forages were fed. The best predictive equation for digestibility of N in the 153 forages studied was DN(%) = -98.1065 + 11.4724 (%CP) + 41.4475 (DE) - .1498 (%...

Two experiments with growing pigs were conducted to investigate the effects of two distinct multienzyme preparations on nutrient digestibility, growth performance and blood profiles. In Exp. 1, a total of 96 pigs (29.7±0.69 kg) were utilized in a 42-day performance and digestibility trial using four dietary treatments: CON (control diet), ENDO (control+0.10% Endopower), NSPase1 (control+0.10% N...

Dietary starch is required for a dry, extruded kibble; the most common diet type for domesticated felines in North America. However, the amount and source of dietary starch may affect digestibility and metabolism of other macronutrients. The objectives of this study were to evaluate the effects of 3 commercial cat diets on in vivo and in vitro energy and macronutrient digestibility, and to anal...

Methane is one of the main greenhouse gases emitted by ruminants around world. It essential to investigate novel approaches increasing animal production while reducing gas emissions from ruminants. This study was conducted examine effect methane inhibitors, such as nitrate, linseed oil, and anthraquinone, on nutritional digestibility, rumen fermentation processes, emission in Sahiwal Gir cattle...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...

effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing 250 g/kg wheat bran, were investigated. on broiler performance and phosphorus degradability and nitrogen digestibility. phytase (500 and 1000 ftu) and xylanase (2700 and 5400 exu) individually and in combination were added to the basal diet and given to 6 replicate groups (4 birds per replicate). at 21...
