this experiment was carried out to compare the effects of treated and untreated wheat straw with pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (bcs) after parturition. thirty kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. synchronization of estrus in sheep has been achieved with the use of i...

The objective of this study was to evaluate the effect of an exogenous amylase preparation on digestion of low- and high-starch diets in dairy cattle. Rumen and total-tract nutrient digestibility were measured in a 4×4 Latin square design with 28-d periods using 4 first-lactation cows cannulated at the rumen and duodenum. Corn silage-based diets had 20 or 30% starch, attained by changing the co...

The objective of this study was to evaluate the effects of replacing dry ground corn with crude glycerol on intake, apparent digestibility, performance, and carcass characteristics of finishing beef bulls. A completely randomized block design experiment with 25 d for adaptation and 100 d for data collection was conducted, in which 3,640 Nellore bulls (367 ± 36.8 kg; 18 ± 3 mo) were blocked by b...

The nutritive value of pistachio epicarp (PE) was evaluated by in situ and in vitro techniques. Chemical analysis indicated that PE was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). Total phenols, total tannins, condensed tannins and hydrolysable tannins contents in PE were 8.29%, 4.48%, 0.49% and 3.79%, respectively. Ruminal dry matter and crude ...

This study aims to determine the digestibility of perilla seeds (Perilla frutescens) in 3 levels (0, 2.5, and 5%) rations given local ducks. The research material used was male Mojosari ducks (Day Old Duck) with as many 90 tails, an average initial body weight 35.36 grams. ration consists ground corn, pollard, fine bran, soybean meal (SBM), vitamin premix, seed supplementation. Livestock separa...

this study was conducted to investigate the effects of different doses of salvia mirzayanii essential oils on gas production parameters, fermentation characteristics using gas production and dual flow continuous culture system. trearments in the gas production experiment was adding 0, 400, 800, 1200, 1600, 2000, 2400 and 4800 mg/l of salvia mirzayanii essential oils to the media. in the second ...

Two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (PB) extract. PB was soaked in water with a ratio of 1:5 (w/v) for 12 h. After filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

introduction using agricultural-industrial waste is one way to overcome the shortage of animal feed. potato is one of the most important products in the world after rice, wheat and maize. potato pulp is a by-product which remains after extraction of starch, and can be used as animal feed. because of the high moisture content of the potato pulp, silage is the best way to maintain it. however, it...

Two experiments were conducted to investigate the feeding value of wood vinegar in weanling pigs. In Experiment 1, weanling pigs (n = 224; Landrace×Yorkshire×Duroc, 21±3 d-old, initial BW 6.12±0.10 kg) were assigned to four dietary treatments. Different levels of wood vinegar were added to the diets as dietary treatments (0, 0.1, 0.2 and 0.3%). Each treatment comprised 4 replicates with 14 pigl...
