Dolenec, Z.: Breeding characteristics of the barn swallow (Hirundo rustica) in NW Croatia. Nat. Croat., Vol. 11, No. 4., 439–445, 2002, Zagreb. The research was carried out in the village of Mokrice (46°00'N, 15°55'E) in NW Croatia during 1998–1999. Egg length averaged 19.16 mm, egg breadth 13.72 mm, egg volume 1840.8 mm3, egg shape index 1.40 and egg weight 1.81 g (during both years). The nest...
Rotifers are widely used in hatcheries to feed small-sized aquatic larvae although one of their disadvantages is the lack zinc and selenium 5- 30-fold lower than copepods, respectively. To improve rotifers quality, different concentrations (2, 4, 5 10 mg L−1 each mineral) were added medium microalgae Isochrysis aff. galbana Nannochloropsis oculata for 4 days, then harvested concentrated rotifer...
The objective of the present study was to evaluate the probiotic effects of different concentrations of four selected native Lactobacillus strains on laying performance and egg quality parameters of quails. To do this, a six-week farm trial was performed in completely randomized design with seven different probiotic treatments of four replicates each consisting of eight quails, resulti...
In a previous article, we described our approach to implementation of effective environmental enrichment, which begins with the diagnosis of environmental features to determine how well they meet the behavior and welfare needs of indoor-housed cats. We formulate this diagnosis based on a pertinent history and physical evaluation. A pertinent history allows us to identify features of the cat and...
The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites. Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four replicated cages containing eight birds per cage. Dietary treatments replaced fresh soybean oil in the control diet (3% fresh soybean oil, 15.25...
field studies were conducted during the cotton crop seasons in 2003 and 2004 at ccs haryana agricultural university, hisar, to identify mortality factors in the egg stage of helicoverpa armigera (hübner) (lepidoptera: noctuidae) in the insecticide-free cotton fields to gain an insight into the role of these factors in causing egg specific mortality. eggs were collected from cotton fields on dif...
This study was conducted to evaluate the effect of different levels of sunflower meal (SFM) and niacin on laying hens performances, biochemical parameters, antioxidant status, and egg yolk cholesterol concentration. A total of 960, White Leghorn (Hy-Line W-36) commercial layers were randomly assigned to 12 groupsof 8 replicates with 10 hens each. Hens were allocated to diets 1 through 12 in a 3...
heavy metals in the surface sediments of the two coastal ecosystems of cochin, southwest india were assessed. the study intends to evaluate the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index. the inverse relationship of cd and zn with texture in the mangrove sedimen...
this experiment carried out to evaluate replacing effects of oyster shell (os) with filter cake (fc) of sugar beet industry on performance and quantity and quality of egg in laying hens .in this trial the filter cake in two physical forms of powder and pellet in five levels of 0, 25, 50, 75, and 100% replaced for oyster shell. each treatment had 3 replications. the experiment lasted 3 periods...
