Características produtivas de novilhas submetidas à restrição alimentar e dieta suplementada com vitaminas D e E. Repositório Alice
PARRILI, M.; MATSUHARA, S.A.; ARRIGONI, M.D.B.; MARTINS, C.L.; MILLEN, D.D.; PACHECO, R.D.L.; SARTI, L.M.N.; BALDIN, S.R.; PARRA, F.S..
O objetivo deste trabalho foi avaliar os efeitos da restrição alimentar e de dieta de suplementação com vitaminas D e E sobre o desempenho e características de carcaça de novilhas Canchim. Vinte e quatro fêmeas, com peso vivo inicial médio de 251,95±18,49 kg, foram distribuídas em quatro tratamentos: alimentação em quantidade restrita e não restrita, com e sem suplementação de vitaminas D e E. Utilizou-se o delineamento inteiramente casualizado, em arranjo fatorial 2x2, com seis repetições. Os animais com alimentação restrita receberam, por 48 dias, 70% da dieta fornecida ao grupo de alimentação não restrita. Após o período de restrição (peso médio de 300,10 kg), eles voltaram a receber ração à vontade por mais 77 dias, até atingirem peso de abate de 380...

Effect of chronic exposure to ammonia on growth, food utilisation and metabolism of the European sea bass (Dicentrarchus labrax) ArchiMer
Dosdat, Antoine; Person, Jeannine; Coves, Denis; Dutto, Gilbert; Gasset, Eric; Le Roux, Annick; Lemarie, Gilles.
The chronic effects of exposing sea bass (average initial weight 100 g) to ammonia in water at 22 degreesC were first evaluated over a 61-day period (period 1, P1) during which nine different groups were submitted to nine ambient ammonia levels ranging from 0.014 to 0.493 mg 1(-1) NH3-N (0.53-16.11 mg 1(-1) total ammonia nitrogen (TA-N)) and fed using self-feeders. At the end of P1, the fish were starved for 10 days (P2). Their recovery capacity was tested over 43 days (P3) after which the exogenous ammonia supply was stopped in all treatments and the fish were allowed to feed. After 20 days of exposure a highly significant effect of ammonia was evident from the decrease in feeding activity, voluntary feed intake (VFI) and specific growth rate (SGR), and...

Effect of past nutritional history and fasting on feed intake and growth in rainbow trout Oncorhynchus mykiss ArchiMer
Boujard, Thierry; Burel, Christine; Medale, Francoise; Haylor, Graham; Moisan, Annick.
Groups of juvenile rainbow trout were fed to satiation for 10 days after 1, 11 and 21 days of feed deprivation. These fish (initial body weight =20 +/- 2 g) were previously fed at different feeding levels (0.5 or 1.5% initial body weight, to satiation) with a high (20.4 kJ . g(-1)) or a low (16.2 kJ.g(-1)) digestible energy diet content for 34 days. It is shown that past nutritional history affected growth performance: duration of feed deprivation has a major effect on intake and feed conversion efficiency; previous feeding level has an effect on intake; dietary energy content affected feed conversion efficiency. In addition, an attempt was made to identify some of the metabolic parameters that could be involved in the increase in growth performance during...

In search for indirect criteria to improve feed utilization efficiency in sea bass (Dicentrarchus labrax) Part II: Heritability of weight loss during feed deprivation and weight gain during re-feeding periods ArchiMer
Grima, Laure; Chatain, Beatrice; Ruelle, Francois; Vergnet, Alain; Launay, Amandine; Mambrini, Muriel; Vandeputte, Marc.
Selective breeding to improve residual feed intake (RFI) in sea bass (Dicentrarchus labrax) is a major goal that would optimize economic gain while minimizing the environmental impact of production. Due to the difficulty in accurately measuring individual feed intake, no selective breeding program has yet been started. In a previous study, we identified a criterion phenotypically related to RFI variations: the loss of weight during feed deprivation, FD. Moreover, an additional composite criterion (CC) integrating both FD and weight gain during subsequent re-feeding (RF) was closely related to RFI, even though the relationship was only close to significance (P=0.06). The aim of the present study was to estimate the heritability of these two traits, in order...

In search for indirect criteria to improve residual feed intake in sea bass (Dicentrarchus labrax) Part I: Phenotypic relationship between residual feed intake and body weight variations during feed deprivation and re-feeding periods ArchiMer
Grima, Laure; Vandeputte, Marc; Ruelle, Francois; Vergnet, Alain; Mambrini, Muriel; Chatain, Beatrice.
No commercial breeding programs have yet started to improve feed utilization efficiency in fish, mainly because of the difficulty in accurately measuring individual feed intake in fish reared in groups. Our general goal is to propose indirect criteria to be used for breeding of commercial lines. In a previous study undertaken with rainbow trout clones, a genetic correlation was detected between residual feed intake (RFI), and body weight variation during successive periods of feed deprivation (FD) and re-feeding (RF). To assess the pertinence of such indirect criteria for future breeding programs, we set up a large experiment using sea bass (Dicentrachus labrax), a recently domesticated species with broad genetic diversity. The objectives of the present...

Physiological mechanisms underlying a trade-off between growth rate and tolerance of feed deprivation in the European sea bass (Dicentrarchus labrax) ArchiMer
Dupont-prinet, A.; Chatain, Beatrice; Grima, L.; Vandeputte, Marc; Claireaux, Guy; Mckenzie, David.
The specific growth rate (SGR) of a cohort of 2000 tagged juvenile European sea bass was measured in a common tank, during two sequential cycles comprising three-weeks feed deprivation followed by three-weeks ad libitum re-feeding. After correction for initial size at age as fork length, there was a direct correlation between negative SGR (rate of mass loss) during feed deprivation and positive SGR (rate of compensatory growth) during re-feeding (Spearman rank correlation R=0.388, P=0.000002). Following a period of rearing under standard culture conditions, individuals representing 'high growth' phenotypes (GP) and 'high tolerance of feed deprivation' phenotypes (DP) were selected from either end of the SGR spectrum. Static and swimming respirometry could...

The effect of feeding restriction with cassava flour on carcass composition of broilers JARTS
Toukourou, Youssouf; Issifou, Dassouki Sidi; Alkoiret, Ibrahim Traore; Paraïso, Armand; Mensah, Guy Appolinaire.
In order to promote poultry farming in resource-limited rural areas, the effects of feeding restriction with cassava flour on the carcass composition of broilers was studied. After three weeks on a restrictive diet (step 1), the broilers were re-fed during four weeks according to their physiological needs (step 2). In total, 75 four-weeks old chicks were randomly divided into three lots of 25 subjects. Lot I (control) is fed without cassava flour. The lots II and III are fed with diets containing respectively 10 and 30 % of cassava flour, with energetic and protein density of 85 and 70 % of the control. Eight broilers of each lot have been randomly selected and slaughtered at the end of each step. At the end of the restrictive step, the carcass yields and...
