The present investigation was undertaken to establish anatomical norms on gross anatomical, histological and histochemical parameter of ovary of Pati and Chara-Chemballi ducks. In present investigation, twelve each Pati and Chara-Chemballi ducks in their laying periods at 42 weeks of age were utilized. After collection of sample, it was processed as per slandered method. The mean value of lengt...

1. Forty-six flocks of commercially-reared Pekin ducks were studied in 23 houses differing in their ventilation and brooding systems, and water and feed resources, in order to identify factors affecting duck welfare in commercial practice. 2. A wide range of environmental variables were measured, together with the physical and plumage condition of the ducks at two ages, whilst companies supplie...

BACKGROUND Wild waterfowl are considered as the natural reservoir for avian influenza (AI) viruses. Bangladesh has been experiencing highly pathogenic avian influenza (HPAI) outbreaks since 2007, mostly in chickens and occasionally in ducks. Ducks play an important role in the persistence and genetic recombination of AI viruses. This paper presents the results of serological and virological mon...

There have been recent calls to develop protocols that collect unambiguous measures of behaviour using automatic techniques in conditioning experiments on magnetic orientation. Here, we describe an automated technique for recording the behaviour of Pekin ducks in a conditioning test that allows them to express unrestricted searching behaviour. Pekin ducks were trained to find hidden food in one...

Significance to the Landscape and Nursery Industries In the face of California’s rapid population growth, the competition for increasingly limited water resources has necessitated the use of recycled water for landscape and nursery irrigation. A reference list of the sensitivity of plant species to recycled water would facilitate implementation of recycled water irrigation. The information gene...

This study aims to determine the effects of local duck mating patterns (Tegal and Magelang) on production performance based feed consumption, conversion (FCR), egg (DDP). The research used 80 Magelang Tegal ducks. is an experimental with a completely randomized design (CRD). 4 treatments 5 replications. number ducks in each cross consisted (five) males 15 (fifteen) females. P1 crossed (MM), P2 ...

A variant designated "cherry-red" is frequently observed in common flue-cured tobacco varieties. This variant has a dappled red coloration of the cured leaf. Cherry-red and red-free selections have been obtained from Nicotiana tabacum, L. cv. 401. Analysis of these selections for alkaloids showed that the cherry-red selection had a much higher nornicotine content than the red-free selection. Co...

Animal pollination is essential for the reproductive success of many wild and crop plants. Loss and isolation of (semi-)natural habitats in agricultural landscapes can cause declines of plants and pollinators and endanger pollination services. We investigated the independent effects of these drivers on pollination of young cherry trees in a landscape-scale experiment. We included (i) isolation ...

BACKGROUND Numerous antioxidant and anti-inflammatory agents have been identified in tart cherries. OBJECTIVE To test the efficacy of a tart cherry juice blend in preventing the symptoms of exercise induced muscle damage. METHODS This was a randomised, placebo controlled, crossover design. Fourteen male college students drank 12 fl oz of a cherry juice blend or a placebo twice a day for eig...

In Egypt, ducks kept for commercial purposes constitute the second highest poultry population, at 150 million ducks/year. Hence, ducks play an important role in the introduction and transmission of avian influenza (AI) in the Egyptian poultry population. Attempts to control outbreaks include the use of vaccines, which have varying levels of efficacy and failure. To date, the effects of vaccine ...
