Kiwi hatching success and chick survival were compared under two incubation protocols and two chick-rearing procedures, to fine-tune the procedure and determine best practice in terms of hatching rate, chick survival and growth. Analysis of the combined 1998/1999 and 1999/2000 data show 10 live chicks from 12 eggs incubated under Protocol 1, compared with 7 live chicks from 13 eggs under Protoc...

This study was conducted to assess the influence of dietary CP and ME on growth parameters of the French guinea fowl, a meat-type variety. In a 2 x 3 x 3 factorial arrangement, 297 one-day-old French guinea keets (162 females and 135 males) were randomly assigned to experimental diets comprising 3,050, 3,100, and 3,150 kcal of ME/kg, each containing 21, 23, and 25% CP from hatch to 4 wk of age ...

fish larvae experience major cellular and biochemical changes during their early life stages.the aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin c content during the different life developmental stages ofhypophthalmichthys molitrix. eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...

The experiment aimed to study the effect of post-hatch early held feeding times starter supplemented with egg yolk and white on growth performance, viscera development and immune response in broiler chickens. The working hypothesis was based on the fact that better development of the gastrointestinal tract and immunity system in the first week of the chicks' life affects positively the growth p...

This study evaluated effects of three products of dietary organic acids (Acidomix® AFG; Activate® AD and Lacplus) on protective immunity against coccidiosis. Two hundred and eighty 1-day broiler chickens were randomly divided into 8 groups by 5 replications (7 birds per replicate), comprising 2 controls (negative=N; positive=P) and 6 supplemented organic acid groups (1% AFG, 1% DA, 1% Lacplus; ...

BACKGROUND The high prevalence of obesity has called attention to the near-intractable problem of sustained weight reduction and its underlying mechanisms. With diet-induced weight loss, achieved body weight is closely related to initial body weight. OBJECTIVE The objective was to compare the relation between initial and achieved body mass index (BMI) in patients treated with diet-induced wei...

Motivated both by the advantage of Hatch filter gain over Kalman-type gain in carriersmoothed-code filtering, this paper proposes a position-domain Hatch filter for differential kinematic satellite positioning. In general, position-domain filtering is more attractive than range-domain filtering since less information is lost if changes in the visible satellite set occurs frequently. A new inter...

Little is known about the genetics controlling the rate of embryonic development in salmonids, despite the fact that this trait plays an important role in the life history of wild and cultured stocks. We investigated the genetics of embryonic development rate by performing an analysis of quantitative trait loci (QTL) on two families of androgenetically derived doubled haploid rainbow trout prod...

Avian embryogenesis can be manipulated by alteration of the temperature during incubation of the brooding egg. Investigations in turkeys showed that a higher temperature during early embryogenesis positively affects the myogenesis accompanied with a higher muscle fibre number (MFN). The aim of this study was to transfer this result to broiler and to investigate if an alteration of the temperatu...
