The response of turkeys to dietary balanced protein during two periods of growth.

1. Two experiments were conducted to measure the response of growing turkeys to dietary protein content. In the first, 960 sexed British United Turkey (BUT 6) poults were used to measure the response to balanced protein from 3 to 6 weeks of age.

Dietary energy:protein ratio influences the efficiency of utilisation of dietary protein by growing turkeys.

1. The following experiment was designed to confirm that the efficiency of dietary protein utilisation (ep) can be reduced when the AMEn to digestible crude protein (DCP) ratio of the feed falls below a critical level. In addition, whether the efficiency would be improved at high DCP contents through the addition of oil or starch was determined.

The potential role of feed restriction on productivity, carcass composition, meat quality, and muscle fibre properties of growing rabbits: A review.

After weaning rabbits, two post-weaning feed restriction (FR) programs are used: a quantitative FR (quantity of feed-limited or time-limited access to feed) or a qualitative FR (modification of diet composition in particularly protein, energy or fibre). Application of post-weaning FR has potential to control post-weaning digestive disorders, and early lower growth rates may be compensated for by later compensatory growth. FR strategies also have potential to enhance feed conversion ratio and reduce carcass fatness.

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.

Breast meat quality in males and females of fast-, medium- and slow-growing chickens fed diets of 2 protein levels.

The aim of this study was to evaluate the effects of genotype, sex, dietary protein level, and their interactions on select carcass characteristics and meat quality of fast- (Ross 308), medium- (Hubbard JA757) and slow-growing (ISA Dual) chickens (n = 2,520). The diet of the low-protein group of chickens had 6% lower CP than the commercial diet fed to the control group. When the chickens reached an average live weight of 2 kg, 10 males and 10 females of each genotype and the diet were selected for slaughter and breast meat-quality analysis.

Research Note: The effects of genotype, sex, and feeding regime on performance, carcasses characteristic, and microbiota in chickens.

The aim of the present study was to evaluate the effects of quantitative feed restriction (FR) in fast-, medium-, and slow-growing meat-type male and female chickens on their growth, feed consumption, economic efficiency, carcass composition, and gastrointestinal microbiota. In the experiment, fast-growing Ross 308, medium-growing Hubbard JA 757 and slow-growing ISA Dual chickens of both sexes were exposed to quantitative FR between 14 and 21 d of age. During the FR, restricted chickens received 70% of the amount of feed consumed by the ad libitum (AL) group.

[Importance of fixed-dose combinations in cardiovascular prevention: the possibility of treating two diagnoses with a single pill].

In the care of a cardiovascular risk patient there is certainly a more frequent situation in which we try to influence several risk factors at the same time. Treatment of a single self-occurring risk factor is rather an exception. In most cases, we need to intervene with more risk factors, often involving combination therapy, which can achieve the desired goals more quickly and reliably.

[Atherosclerosis and beta-blockade: A forgotten option?].

Beta-blockers have been ranked fourth in management recommendations for arterial hypertension in the management of arterial hypertension. This “retreat” is justified by the results of studies comparing different antihypertensive strategies that documented a lesser benefit of the beta-blockers tested compared to control therapies. Obviously, even within the beta-adrenergic receptor blocking group, there are important differences between agents.

Changes in the quality of eggs during storage depending on the housing system and the age of hens.

The objective of the study was to evaluate changes during storage time (0, 7, 14, and 21 D) in the weight, albumen quality and its functional properties, and protein content of eggs from enriched cage and free range at 26 and 51 wk of age. Egg weight was affected by a significant interaction between the housing system and the age of hens. Regarding individual factors, heavier eggs (P < 0.

The growth of turkeys 1. Growth of the body and feathers and the chemical composition of growth.

1. The potential growth of modern turkey genotypes was measured using male and female BUT 6 (BUT) and Hybrid Converter (HYB) strains. At one-day-old, 720 male and 960 female poults were randomly allocated to 48 littered pens in two houses with 30 males or 40 females of each strain per pen.

The growth of turkeys 2. Body components and allometric relationships.

1. The relationships between the main components of the body and body protein among males and females of BUT 6 (BUT) and Hybrid Converter (HYB) turkey strains were examined. 2.

Age related changes in laying pattern and egg weight of different laying hen genotypes.

The aim of the study was to evaluate changes in laying patterns depending on the age of different genotypes of laying hens. In the experiment, six genotypes were evaluated (brown-egg hens Bovans Brown, Bovans Sperwer and Isa Sussex, white-egg hens Dekalb White, and laying hens with tinted shells Moravia Barred and Moravia BSL) in three periods during the laying cycle (the onset of lay between 20 and 26 weeks of age, the middle from 36 to 42 weeks of age and the end of lay between 64 and 70 weeks of age). A significant interaction between genotype and age was apparent in mean sequence length (P<0.

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.

Age-related changes in the carcass yield and meat quality of male and female nutrias (Myocastor coypus) under intensive production system.

The age at which final nutria weight is achieved varies in literature between six and 14months. The aim of this study was to evaluate the growth, carcass composition and meat quality of male and female nutrias between the ages of six and eight months in intensive production system. Sexual dimorphism in growth was observed from three months of age, and in females, growth considerably decreased after six months of age.

[Cholesterol metabolism in patients with type 2 diabetes].

Diabetic dyslipidemia is a complex disorder associated with changes in lipid metabolism, which must be considered during care of the diabetic patient. Type 2 diabetes mellitus is a disease associated with a number of macrovascular and microvascular complications and it is necessary to treat the patient with regard to the possibility of developing these disorders. Prevention of cardiovascular complications is one of the most important factors of diabetes care, because cardiovascular diseases are among the leading causes of morbidity and mortality in patients with diabetes mellitus.
