The immune system is a life history trait that can be expected to trade off against other traits. Whether or not considered has consequences for the expectation on how it responds natural selection and evolution; in addition, may have outcome of artificial when included breeding objective. involved pathogen resistance comprises multiple mechanisms define host's defensive capacity. Immune involves employing either prevent pathogens from invading eliminate they do invade. On hand, tolerance...
Coping styles in response to stressors have been described both humans and other animal species. Because coping are directly related individual fitness they part of the life history strategy. Behavioral trade off with traits through acquisition allocation resources. Domestication subsequent artificial selection for production specifically focused on individuals energy sparing mechanisms non-production traits. resulted animals low levels aggression activity, a hypothalamic-pituitary-adrenal...
Abstract Climate change can have a negative impact on agricultural production and food security. Vice versa, practices themselves contribute to climate because of land, water, energy use anthropogenic emissions greenhouse gasses waste. The European Green Deal focusses “transition sustainable system that has neutral or positive environmental impact, helps mitigate adapt its reverses the loss biodiversity”. Local feed proteins in Union may result new agro-ecosystem services be integrated...
There is an urgent need to identify the effects of temperature on production traits. This study aimed determine impact pig in three environments (T°Cgrowing-°Cfattening-°Cfinishing = T24-24-21, T19-19-19, and T23-17-15) growth curve parameters, body weight gain (DBWG), feed intake (DFI), efficiency during growing, fattening finishing stages, carcass yield primal cuts (ham, shoulder, loin) 158 Duroc × Iberian pigs. Maturation rate was higher T23-17-15 than T19-19-19 (P < 0.001). Pigs reached...
Because feed is the major cost to pork production, management practices and breeding strategies are aimed at optimizing intake. Knowledge about shape of intake feeding behavior curves may be interest for optimization lean meat production. This study investigated trends based on daily measurements in 200 Duroc barrows, originating from 5 sires dams, during growth. Daily values were examined between 88 188 d age. Furthermore, phenotypic correlations length rate, frequency, intake, residual...
Heat stress (HS) is one of the costliest issues in U.S. pork industry. Aims present study were to determine consequences repeated exposure HS on growth performance, and effects a high fiber diet, genetic potential for lean tissue accretion, residual feed intake (RFI) resilience HS. Barrows (n = 97) from three lines (commercial, RFI, low RFI) where subjected times 4-day treatment (HS1, HS2, HS3) which was preceded by 9-day neutral (TN) adaptation period (TN1) alternated 7-day periods...
Abstract Circular economic principals of production are based on material flows through the system with minimum external inputs, recycling resources, generating waste, emissions, or pollution. Agriculture presents a major opportunity for utilization wastes, by‐products and co‐products in development circular economy via design agricultural systems creation new sustainable value chains. The present work outlines an illustrative example bee↺legume↺poultry system, premise that: (1) there is...
Environmental challenges may adversely affect poultry production. Autochthonous breeds are particularly valuable in a climate change context because of adaptation to the local environment. The objective present study was determine impact cold stress, water restriction, and heat stress on response quantified by heterophil lymphocyte ratio (H/L) ten Spanish laying hens. Hens these were consecutively subjected three treatments: natural (2, 4, 6, 7, 9, 13 °C), restriction (with duration 2.5,...
The feasibility and economic value of DNA paternity identification were investigated illustrated using Nevada beef cattle operations. A panel 15 microsatellites was genotyped in 2,196 animals from 8 ranches with a total 31,571 genotypes. Probabilities exclusion for each marker within ranch across computed. Joint probabilities the also determined, resulting values over 0.99 any individual ranches. Dropping 1 or 2 lowest resulted joint greater than marginal reduction compared microsatellites....
Play behavior has been proposed as a new potential indicator of animal welfare. Animals play only if they are in relaxed state. may improve adaptability to challenging environments which be interest the breeding objective. Little information is available on livestock species. The aim present study investigate whether post-weaned piglets can induced instantly presence additional space and markers body weight, sex, litter dependent. It investigated playfulness elicited by moment or this...
Feed efficiency (FE) is a valuable trait, yet how genetic selection for enhanced FE affects other processes such as response to disease unknown. Disease from endemic respiratory and enteric pathogens Mycoplasma hyopneumoniae (Mh) Lawsonia intracellularis (LI) are common in swine production. Therefore, the aim of this study was examine if pigs selected high vs. low based on residual feed intake (RFI) respond differently dual challenge. Pigs RFI (LRFI, FE) considered more compared their (HRFI,...
Because feed is the major input in pork production, conversion of into lean tissue at minimum costs has been a focus for improvement. Several researchers have proposed using residual intake (RFI) rather than ratio (FCR) genetic improvement efficiency. Little known about variation RFI pigs. As several studies suggest greater related to animal activity levels, current study investigated phenotypic relationship between and (FI) behavior 104 group-housed growing Duroc barrows allowed ad libitum...
Little is known about the relationship between feed intake behaviour and cholesterol levels in humans. This can be attributed to fact that humans difficult assess. The relationships intake, efficiency behaviour, triglyceride were investigated at an average age of 187 days, a pig model consisting 202 Duroc barrows. Feed recorded individually daily by means electronic identification system. Animals with high total also had high-density lipoprotein (HDL), low-density (LDL) triglycerides. HDL...
