A trial with twenty-four newly weaned Awassi lambs (initial body weight=21.5±0.8 kg) was conducted using a 3×2 factorial design to study the effect of feeding three sources of protein supplements (soybean meal (SBM), sunflower seed meal (SSM), and cottonseed meal (CSM)), either untreated or formaldehyde-treated on the growth performance and carcass traits of Awassi lambs. Lambs were randomly as...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
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...
Diets with low forage concentration may depress feed intake and average daily gain, while diets with high forage concentration may limit feed intake due to rumen filling. Adequate forage level may range from 7% to 14% in ration for feedlot lambs, depending on forage source and ingredient composition. Small amounts of good quality forage may improve growth performance of sheep in the first stage...
An experiment was conducted under completely randomized design to study the effect of different levels of probiotic (500 and 1000g/feed for 1st phase (25 days) i.e. 35-60 days and at the levels of probiotic (250 and 500g/feed) as 2nd phase (50 days) i.e. 60-110 days. 90 rock partridges (35 day old) were randomly distributed into three treatments and five replicates (6 birds in each replicate) w...
An experiment was conducted to determine if the improved creep feed intake observed during intermittent suckling (IS) is important for postweaning performance. Therefore, creep feed intake of litters was assessed, and within litters, eaters and noneaters were distinguished using chromic oxide as an indigestible marker. Batches of sows were suckled intermittently (IS, 7 batches; n = 31) or conti...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
this study was carried out to assess the effects of alfalfa hay level and replacing corn grain by other grains in starter on daily feed intake, average daily gain (adg) and feed efficiency (fe) of pre and post-weaning dairy calves during the pre and post-weaning periods. for this purpose, a database meta-analysis used in the present study. statistical analyses were performed using proc mixed in...
This experiment investigated the effect of feeding different levels of sesame oil cake on the intake and digestibility of DM, CP, crude fiber, and crude fat in Awassi fattening lambs. Sesame oil cake was incorporated into lamhs’ rafions at levels of 10 and 20% to replace similar percentages of barley and soybean. The results showed that the high level of sesame oil cake inclusion decreased DM a...
