Ramifications of Heat Stress on Rabbit Production and Role of Nutraceuticals in Alleviating Its Negative Impacts: An Updated Review.

Heat stress has become a widespread concern worldwide, which is a major environmental stress that causes substantial economic loss in the rabbit industry. Compared to other agricultural animals, rabbits are more sensitive to heat stress as they have fewer sweat glands and a thicker coat of fur, increasing the heat dissipation complexity. Thus, heat stress hurts rabbits' productivity, meat quality, reproductive performance, antioxidative properties, immune responsiveness, intestinal histomorphology, and microbiome.

Dietary Inclusion of Crickets () and Yellow Mealworm Meal () in Comparison with Soybean Meal: Effect on the Growth, Total Tract Apparent Digestibility, and Nitrogen Balance of Fattening Rabbits.

Three diets were formulated, i.e., soybean meal (SM diet), adult (AD diet), and larvae (TM diet), as the main crude protein (CP) sources.

The effect of housing system on rabbit growth performance, carcass traits, and meat quality characteristics of different muscles.

The present study analysed the effect of housing system (caged versus penned) on the growth performance, carcass traits, and meat quality of rabbits. The physiochemical quality of five muscles was evaluated, together with the chemical composition and fatty acid profile of the meat from the hind leg. Sensory properties of the longissimus lumborum (LL) was also assessed.

Metabolic Effects of a Hydrophobic Alginate Derivative and Tetrahydrolipstatin in Rats Fed a Diet Supplemented with Palm Fat and Cholesterol.

The effects of octadecylamide of alginic acid (amidated alginate) and tetrahydrolipstatin on serum and hepatic cholesterol, and the faecal output of fat and sterols, were investigated in rats. Amidated alginate is a sorbent of lipids, tetrahydrolipstatin is an inhibitor of pancreatic lipase. Rats were fed diets containing cholesterol and palm fat at 10 and 70 g/kg, respectively.

The effect of feed restriction, sex and age on the carcass composition and meat quality of nutrias (Myocastor coypus).

The objective of the study was to evaluate the effect of quantitative feed restriction on the carcass composition and physical, chemical, histochemical and sensory properties of meat from male and female nutria at the end of the feed restriction and fattening period. In the experiment, from two to eight months of age, males and females were divided into two groups: one group was fed ad libitum throughout the experiment, and the second group was restricted to two weeks (from 11 to 12 weeks of age). The restricted nutrias received 75% ad libitum feeding.

Effect of an Outdoor Access System on the Growth Performance, Carcass Characteristics, and Muscle Meat Quality of the Prestice Black-Pied Pig Breed.

The effect of an outdoor-access vs. conventional indoor system on the growth, carcass characteristics, and muscle (LL) meat quality was evaluated in 24 Prestice Black-Pied pigs, during the growing-finishing period. Two groups received the same complete diet and were housed separately under conventional indoor conditions, with only one group having full access to pasture (350 m/pig).

Economic values of rabbit traits in different production systems.

In animal breeding, genetic parameters along with economic weights (EWs) of traits are applied. Profit functions currently used to calculate rabbit traits' EWs do not consider nutrient requirements based on animal weight, growth rate and doe reproductive status. Therefore, the aim of this study was to develop a flexible bioeconomic model of rabbit-production systems and implement it in a computer programme in order to calculate economic values and relative EWs for rabbit traits.

Narrow-leaved lupine seeds as a dietary protein source for fattening rabbits: a comparison with white lupine seeds.

Lupine seeds have the potential to be an alternative to imported dietary proteins. In rabbits, it has been indicated that White lupine seed (WLS) is a suitable protein source. Other lupine species, for example, narrow-leaved lupine seed (NLS), have not yet been tested in rabbit diets.

Effect of amidated alginate on faecal lipids, serum and hepatic cholesterol in rats fed diets supplemented with fat and cholesterol.

The effect of octadecylamide of alginic acid on serum and hepatic cholesterol, and the faecal output of fat and sterols was examined in female rats fed diets containing cholesterol and palm fat at 10 and 50 g kg, respectively. Cholesterol supplementation significantly increased serum and hepatic cholesterol concentrations, and faecal output of cholesterol and coprostanol. Cholesterol and amidated alginate supplementations changed the profile of fatty acids in the faeces.

The influences of dried Chicory root and White lupine added to food on jejunal morphology: experimental study.

Aim: The objective of this work was to test the effects of adding dried Chicory root and White lupine food on small bowel morphology and compare it to a standard commercial diet.

Background: Various commercial gluten-free products, gluten-free raw materials and gluten-free plants are this time available on the food market, but there are still not enough information about their effect on the small bowel morphology.

Methods: Altogether thirty rabbits were used in this study.

Fatty acid composition of goose meat depending on genotype and sex.

Objective: The aim of this study was to compare male and female geese of two contrasting genotypes in terms of fatty acid composition, indexes related to human health, lipid metabolism and oxidative stability of the meat.

Methods: The experiment was carried out on total of 120 geese of two different genotypes; the native breed Czech goose (CG) and commercial hybrid Novohradska goose (NG). One-d-old goslings were divided into 4 groups according to genotype and sex, and 8 birds from each group were slaughtered at 8 weeks of age.

Effect of dietary dehulled white lupine seed supplementation on the growth, carcass traits and chemical, physical and sensory meat quality parameters of growing-fattening rabbits.

This work aimed to extend our current knowledge by obtaining novel information regarding the effect of the dietary inclusion of dehulled white lupine seeds (DWL) on the physical characteristics and sensory qualities of rabbit meat, as well as growth and carcass traits. The DWL diet was compared with a soybean meal-based diet. Feeding the DWL diet to rabbits led to lower Warner-Bratzler shear force values measured in grilled meat samples (Longissimus lumborum muscle) across fibers and this finding was confirmed in the sensory evaluation of texture in terms of higher tenderness and fibrosity of meat samples.

The relationship between hepatocytes and small bowel after early and short food restriction: What the results show in morphometry.

The objective of this study was to evaluate the relationship between hepatocyte morphometry and small bowel architecture after early and short food restriction. Altogether 48 Hyplus broiler rabbits were divided into three groups. The control group was fed ad libitum (ADL) throughout the experiment (C).

The effect of age, genotype and sex on carcass traits, meat quality and sensory attributes of geese.

Objective: The aim of this study was to compare carcass traits, meat quality and sensory attributes in two different genotypes of geese according to age and sex.

Methods: The experiment was carried out on 160 birds of two genotypes of geese: the Czech Goose (CG) breed and a Eskildsen Schwer (ES) hybrid. One-d-old goslings were divided into four groups according to genotype and sex.

Comparative study of the hypocholesterolemic and hypolipidemic activity of alginate and amidated alginate in rats.

Alginate is a copolymer of β-d-mannuronate and α-l-guluronate, which are present in the cell wall of brown algae. The hypocholesterolemic and hypolipidemic activities of alginate and its derivative, which is prepared by a reaction with octadecylamine, were compared in rats fed diets containing cholesterol and palm fat at 10 and 50g/kg, respectively. Amidated alginate at 20g/kg significantly decreased serum cholesterol from 2.

The influence of food restriction on the small bowel: Does intensive short‑term food restriction lead to weight loss?

The objective of this study was to show morphological changes in the small intestine of Hyplus broiler rabbits following an eight‑day food restriction programme. The control group (C) received food ad libitum (ADL) for the duration of the experiment. Group R1 received 50g of food per day, and group R2 received 65g of food per day.

Relationships between variable time, percentage of food restriction and liver histology: which alternative is the best for non-alcoholic fatty liver disease (NAFLD) prevention?

The objective of this study was to analyse the hepatic effects of food restriction in an experimental rabbit model. The study comprised 105 rabbits divided into 6 groups. The two control groups were fed ad libitum (ADL) during the entire experiment (C1 and C2).

The effect of 1-week feed restriction on performance, digestibility of nutrients and digestive system development in the growing rabbit.

A 3 to 4 week feed restriction of about 20% to 25% of the free intake is widely applied in rabbit breeding systems to reduce post-weaning digestive disorders. However, a short intensive feed restriction is described in few studies and can be beneficial for growing rabbits due to a longer re-alimentation period. The aim of this study was to evaluate the effect of ad libitum (AL) and two restriction levels of feeding (50 and 65 g/rabbit per day) applied for 1 week on performance, gastrointestinal morphology and physiological parameters during the restriction and during the re-alimentation period.

Histological aspects of the small intestine under variable feed restriction: The effects of short and intense restriction on a growing rabbit model.

The objective of this study was to investigate the effect of seven days of feed restriction (between days 42 and 49) on the morphology of the small intestine in experimental rabbit models. Sixty weaned Hyplus rabbits (35 days old) were included in the experiment and split into three groups of 20 rabbits. The first control group (n=20) received feed (ADL group), the second (R1) experimental group (n=20) was fed 50 g feed per rabbit per day and the third (R2) experimental group (n=20) received 65 g feed per rabbit per day.

Histopathological aspects of liver under variable food restriction: has the intense one-week food restriction a protective effect on non-alcoholic-fatty-liver-disease (NAFLD) development?

Non-alcoholic-fatty-liver-disease (NAFLD) is a clinicopathologic entity characterized by a variety of hepatic injury patterns without significant alcohol use. It has a close association with obesity, so treatment includes weight loss, control of insulin sensitivity, interventions directed at inflammation and fibrosis. There is a certain relationship between the grade and duration of food restriction and hepatic function.

Effect of diets containing whole white lupin seeds on rabbit doe milk yield and milk fatty acid composition as well as the growth and health of their litters.

The effect of dietary inclusion of white lupin seed (WLS) on the milk composition and yield of rabbit does as well as the performance of their litters was studied. Two lactation diets having identical digestible protein (DP):DE ratio and two weaning diets having identical DP:DE ratio were formulated. The first lactation diet (SL) contained soybean meal (SBM; 13.

Dose-response efficacy and long-term effect of the hypocholesterolemic effect of octadecylpectinamide in rats.

The dose-response efficiency and long-term effect of the hypocholesterolemic effect of octadecylpectinamide was examined in female rats fed diets containing cholesterol at 10 g/kg. In our first experiment, amidated pectin supplied at 20 g/kg, 40 g/kg and 60 g/kg significantly decreased serum cholesterol from 3.32 μmol/ml (control) to 1.

Effect of feeding growing-fattening rabbits a diet supplemented with whole white lupin (Lupinus albus cv. Amiga) seeds on fatty acid composition and indexes related to human health in hind leg meat and perirenal fat.

A total of 20 weaned rabbits (33 days old) (10 per treatment) were fed one of two diets that included 150 g of sunflower meal (SF)/kg of diet or 120 g of whole white lupin (WL)/kg of diet for 42 days. The WL diet contained less saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) but more monounsaturated fatty acids (MUFA) than the SF diet. The WL diet significantly decreased SFA and PUFA content, as well as the PUFA n-6/PUFA n-3 ratio and saturation, atherogenic and thrombogenic indexes in hind leg meat.
