this experiment was conducted to determine the effects of either twice or thrice a day feeding regimens on performance and as well on plasma hormone and metabolite levels of broiler breeder hens during 24 to 38 wk of their productive age. breeder pullets were provided form a commercial flock, and distributed in experimental units, in a compeletly randomized design with three feeding regimens (t...

Clustering is an unsupervised learning method that is used to group similar objects. One of the most popular and efficient clustering methods is K-means, as it has linear time complexity and is simple to implement. However, it suffers from gets trapped in local optima. Therefore, many methods have been produced by hybridizing K-means and other methods. In this paper, we propose a hybrid method ...

Abstract The current objective was to develop imaging techniques characterize osteochondrotic-like lesions (OC-lesions) and evaluate the efficacy of dietary interventions promote lesion regression prevent lameness. Pigs (n=76) were weaned (~6kg) fed 1 2 nursery diets for 3-wk with no supplemental vitamin D, (-D, n=60) or 280 IU D3/kg (+D3, n=20). Following nursery, +D pigs standard (+Ctl) -D al...

background: lead is an industrial heavy metal that can decrease sperm motility. objective: the aim was to investigate the protective effects of calcium against lead on motility of spermatozoa. materials and methods: in total 40 adult male swiss white mice were randomly divided into 5 groups (control, lead of 1st wk, lead of 2nd wk, lead/calcium of 1st wk and lead/calcium of 2nd wk). the lead gr...

Abstract Canine obesity negatively influences health and well-being appears to modify gastrointestinal microbiota populations. Restricted feeding of a specially formulated diet consequent weight loss may be used improve microbiota. In this study, we aimed determine the effects restricted on fecal populations obese dogs. All procedures were approved by University Illinois IACUC prior experimenta...

in the current study, two line with short-term divergent selection for high weight (hw) and low weight (lw) at 4 wk of age after 7 generation were analyzed in coturnix japonica quail. hw line was significantly higher than lw line at 28d of age (p<0.01). 21 females, and 11 male from the hw, 18 females plus 10 male from the lw lines were mated as reciprocal cross and within lines to produce hh, l...

The incorporation of alfalfa (Medicago sativa L.) into bermudagrass [Cynodon dactylon (L.) Pers.] forage systems in the southern US has increased. Stockpiling this mixture may extend grazing season fall and winter months with high-quality forage. objective 2-yr study was to evaluate agronomic structural responses alfalfa-bermudagrass mixtures managed under five stockpiling periods (6, 8, 10, 12...
