Flexible time budgets allow individual animals to buffer the effects of variable food availability by allocating more time to foraging when food density decreases. This trait should be especially important for marine predators that forage on patchy and ephemeral food resources. We examined flexible time allocation by a long-lived marine predator, the Common Murre (Uria aalge), using data collec...

the effect of feeding different protein profiles on growth performance, carcass components and nitrogen content of litter in cobb 500 broiler strain was evaluated using 800 chicks in a completely randomized design with four treatments, five replicates groups of 40 birds per each treatment. the treatments were consisted of four protein feeding profiles (based on cobb strain nutrition guide, reco...

Osteochondrosis is a multifactorial pathology that affects up to 75% of equids and impacts their sports career. Feeding excess dietary concentrates, thus inducing increased blood glucose insulin peaks associated with meals, has been linked an incidence osteochondrosis in foals. The objective the study was analyze effects different concentrate distribution 2 or 8 meals throughout day night on me...

In order to compare the effect of 3,5,3'-triiodothyroacetic acid (TRIAC) with those of triiodothyronine (T3) and thyroxine (T4), severely hypothyroid rats (n=56) were infused over 13 days with 1, 2 or 4 nmol/100 g body weight (BW) per day of T3 or 2, 4 or 8 nmol/100 g BW per day of T4 or TRIAC. The 8 nmol/100 g BW per day of T4 or TRIAC induced the same increase in resting metabolic rate, yet 4...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

The present study was conducted to determine the best feeding rates expressed as percent of body weight in Persian sturgeon fingerlings at different body weights. Eighteen fiberglass tanks each holding 30 fingerlings with an average initial body weight of 19.45 ± 0.5 g were used in this experiment. Six different feeding trials (1, 2, 3, 4, 5 and 6 percent of body weight) were employed an...

BACKGROUND To assess whether monthly home visits from trained volunteers could improve infant feeding practices at age 12 months, a randomised controlled trial was carried out in two disadvantaged inner city London boroughs. METHODS Women attending baby clinics with their infants (312) were randomised to receive monthly home visits from trained volunteers over a 9-month period (intervention g...
