Abstract:

The objective of this study was to examine the effects of rearing temperature on the meat yield of broilers. Four experiments were conducted. Experiment 1 examined meat yield at different temperatures and on different diets when birds were grown to a fixed age. Experiments 2 and 3 were aimed at the effects of temperature and of the interaction between temperature and stocking density respectively on the meat yield of broilers when killed at a specified liveweight (i.e. allowing the rearing period to vary). Experiment 4 was designed to assess whether depression of growth rate at high temperatur

Abstract:

A series of experiments were conducted to investigate the effects of certain biological, nutritional, and processing factors on breast meat quality of broilers. In the first experiment, the influence of genetic strain, plane of nutrition, and age at slaughter on breast meat quality was evaluated. Breast meat from a high yield line of broilers had lower pH at 24 h postmortem (PM), greater L*, a*, and b* values, lower water holding capacity (WHC), and higher expressible moisture (EM) than those of a line selected for rapid growth. Breast meat from birds processed at 42 d had lower WHC than th

Abstract:

Poultry production is one of the few animal sectors still growing due to the high consumer request, guaranteeing high production level and a standardized product. However, the selection of fast growing strains with high breast yield has brought about some defects affecting the meat quality. The alterations most observed under commercial condition, which do not represent an issue for human health but are an economic loss for the stakeholders, are white striping and wooden breast. These abnormalities, which alter the chemical and technological meat quality requiring a further transformation or t

Abstract:

Mechanical and hand catching of broilers were performed to determine if differences existed in breast meat quality among catching methods. Meat quality results were summarized using a two-prong approach to investigate if average differences existed in meat quality through the determination of ultimate pH, rapid pH decline, color, water holding capacity, and tenderness within each treatment and by pinpointing individual quality problems within treatments. Two trials were conducted and revealed greater variation in meat quality during summer in comparison to winter within treatments in both catc

Abstract:

The only available broiler strain to use in organic chicken meat production, until recently, has been conventional fast growing broiler hybrids. The Rowan Ranger is a broiler strain that has a naturally slower growth rate which makes this strain suitable for organic farming, meeting the demands of KRAV without being subjected to a feed restriction. One of the farms in Sweden using Rowan Ranger in their organic production is Bosarp farm in Skåne County where they produce KRAV certified chickens and where the animals used in this study were raised.

In poultry farming, the intestinal microbiota and the “gut health” are topical subjects, especially since the EU has banned the use of auxinic antibiotics to avoid the onset of antibiotic resistance and safeguard the consumer health. As a consequence of their prohibition, a higher incidence of enteric diseases is observed in poultry farming with loss of productivity and increased mortality. In the post-antibiotics era, probiotics and prebiotics are proposed as a solution to the intestinal problems of poultry.

A tal fine, intensa è stata la pressione genetica per ottenere ibridi commerciali altamente produttivi. Tuttavia, i moderni ibridi di pollo sono più sensibili allo stress da calore (HS) e alla insorgenza di anomalie del petto, come Oregon Disease (OD), White Striping (WS), Wooden Breast (WB) e Spaghetti Meat (SM). Una strategia per diminuire lo HS nel settore avicolo consiste nella somministrazione in ovo di pre-probiotici o simbiotici, al fine di migliorare la sa

Questa tesi ha inteso valutare gli effetti di diversi bioattivi somministrati nell’alimento o in ovo sulle performance produttive e le caratteristiche qualitative della carne di pollo. Il primo studio ha avuto l’obiettivo di valutare gli effetti di una preparazione probiotica e di una formulazione simbiotica somministrate nell’alimento, sull’efficienza economica dell’allevamento, le performance e le caratteristiche qualitative della carne di pollo. 360 pulcini femmine di un giorno di età sono stati casualmente divisi in 3 gruppi sperimentali (120/gruppo): dieta base (Controllo, C); dieta base

Abstract:

White Striping (WS) and Wooden Breast (WB) are two emerging myopathies in broiler hybrid chickens, which are gaining great relevance for the poultry sector, due to the huge economical losses ascribable to the unappealing appearance and impaired nutritional and technological quality of af-fected fillets. However, the knowledge concerning their aetiology is not clear and the consequences on meat quality is still incomplete. Therefore, the present thesis, which includes four researches, aimed to deepen the knowledge possessed by the scientific community on these defects. The first study in-vestig

Abstract:

L’intensa selezione genetica ha consentito negli anni di ottenere polli sempre più pesanti nel minor tempo possibile, rendendo gli animali maggiormente suscettibili allo stress ossidativo. La vitamina E, un potente antiossidante naturale, è un micronutriente utilizzato nell'alimentazione animale per migliorare lo stato di salute e la qualità delle produzioni, nonché per ridurre i processi ossidativi nella carne. Recenti studi, hanno dimostrato come la vitamina E, attraverso la marinatura della carne, sia in grado di inibire la formazione di composti cancerogeni in seguito a cottura ad elevate

Abstract:

La tecnologia di iniezione in ovo consente di somministrare componenti bioattivi di origine naturale, quali pre- e probiotici, direttamente nella camera d’aria dell’uovo al 12° giorno di incubazione. Questa via di somministrazione permette di veicolare tali composti il prima possibile ed in condizioni altamente controllate, aumentandone così l’efficacia. Tuttavia, gli studi condotti finora per provare e validare l’efficacia dei prebiotici somministrati in ovo sulla salute intestinale, sulle performance di crescita e qualità della carne non sono del tutto esaustivi, essendo stati tutti condotti

O objetivo do trabalho foi avaliar o efeito de diferentes períodos de jejum alimentar (3, 6, 9, 12, 15 e 18 horas) sobre a perda de peso vivo em frangos de corte criados em sistema convencional e o rendimento de carcaça quente e fria (antes e após o resfriamento), além de avaliar os atributos de qualidade da carne de peito de frango. Neste experimento foram utilizados frangos de corte da linhagem Ross com 46 dias de idade. Os resultados encontrados mostraram que o tempo de jejum prolongado teve efeito significativo (p≤0,05) sobre a perda de peso das aves antes do abate, com perda de 5%
