Two studies were conducted to identify methods for treating crop residues to improve digestibility and value in finishing diets based on corn grain and corn wet distillers grain with solubles (WDGS). In Exp. 1, 336 yearling steers (initial BW 356 ± 11.5 kg) were used in a 2 × 3 + 1 factorial arrangement of treatments with 6 pens per treatment. Factors were 3 crop residues (corn cobs, wheat stra...

This study evaluated nitrogen (N) mineralization dynamics in three soils after the addition of heat-treated urban waste amendments or compost (UWC). The effects UWC and urea on soil properties broccoli lettuce production were compared. first N experiment was conducted a factorial arrangement (4 × 3), as randomized complete block design (RCBD), with replicates. Four doses: 12.5, 25.0, 37.5, 50.0...

We introduce a new combinatorial object, the double-permutation sequence, and use it to encode a family of mutually disjoint compact convex sets in the plane in a way that captures many of its combinatorial properties. We use this encoding to give a new proof of the Edelsbrunner-Sharir theorem that a collection of n compact convex sets in the plane cannot be met by straight lines in more than 2...

A study was conducted to investigate the effects of different betaine (BET) (0.0, 0.5 or 1.0 g/kg) and folic acid (FA) (0.0, 4.0 or 8.0 mg/kg) levels on performance, egg FA concentration and egg production of laying quails using 288 forty-two day-old Japanese quail in a 3 × 3 factorial arrangement of treatment based on randomized complete design. The results showed that none of the performance ...

ABSTRACT The use of organic fertilizers can improve the chemical, physical, and biological properties soil, with their implying low environmental impact. This study aimed to evaluate yield quality yellow passion fruit grown in an system associated irrigation input levels. A randomized complete block design a 3x2 factorial arrangement four replications was adopted. factors evaluated were: three ...

Two 21-d experiments were conducted to evaluate the effects of low phytate barley (LPB) on Zn utilization by young broiler chicks and to determine the contribution of endogenous phytase, present in LPB. In the first experiment, ninety-six 1-d-old male chicks were assigned to a 2 x 3 factorial arrangement of treatments (4 pens of 4 chicks/treatment). Factors were barley type [wild-type barley (W...

this experiment was conducted to evaluate the effect of different lipid sources and organic zinc supplementation on performance, egg bacterial activity and ovary morphology of laying hens for 10 weeks. with 288 sixty weeks old birds by employing a completely randomized design with factorial arrangement of 3×4 with 12 treatments, 4 replicates and 6 hens each. the factors of interest were 4% lipi...

An experiment was conducted to study the effects of substitution soybean meal (SBM) with canola meal (CM) and formulated diets based on total and digestible amino acid on performance, egg quality, organs weight and blood parameters of laying hens from 73 to 83 weeks of age. A total of 128 laying hens were distributed by completely randomized design in a 2×2 factorial arrangement with 2 protein ...
