Set Up

1.Major changes have taken place in the beef industry over recent years - in particular, the introduction of several continental breeds which have the potential for producing larger and leaner carcases. The Canadian Holstein has also been used extensively in the dairy industry, replacing British Friesians, with the result that beef cross carcasses from the dairy herd have tended to be larger and have poorer conformation.2.As a consequence of these changes there is concern in the industry that beef of poorer eating quality is now being produced. For this reason, and to aid in the development of MLC's Blueprint for beef eating quality, this trial was set up in collaboration with Genus to evaluate the eating quality of two traditional British beef breeds and four continental breeds slaughtered at different fatness levels. 3.All progeny included in the trial were from Holstein Friesian type dams. They were sired by the following breeds:- Limousin (LM), Charolais (CH), Belgian Blue (BB), Piemontese (PM), Aberdeen Angus (AA) or Hereford (HF) and were finished on an 18 month beef production system.

Impossible Task

The purpose of this prologue is to outline how I have approached the arrogant and impossible task of surveying an unborn century of law. I may also be able to illustrate that the nature and quality of the task is completely different from that attempted in the preceding papers. In the whole paper I have done little more than infer repeatedly, in different ways (a) that the shape of the future so far as law is concerned will be determined by the methods of communication adopted between sectors of the aerospace community and between the aerospace community and society at large, and (b) that the search for effective methods of communication is urgent. But my target is not the lawyers of our community—who I am not qualified to advise. I write for the other members of the Royal Aeronautical Society and I return to the task of persuading them that they have a role to play in evolving future laws for aerospace activities.

AbstractThe increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42 spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and 14 Charolais × Holstein-Friesian (CH)] were reared to slaughter at between 26 and 37 mo of age. Carcass weight was higher and the lipid concentration of m. longissimus thoracis et lumborum was lower (P < 0.05) for CH than the dairy breeds. Overall acceptability tended to be lower (P = 0.055) while tenderness, texture and chewiness were lower (P < 0.05) for CH compared with the dairy breeds. The proportion of C16:1 in the total lipid tended to be lower (P = 0.055) for CH than the dairy breeds. Replacing male offspring of traditional “Irish” Friesian bulls with offspring from a genetically superior (from a dairy perspective) strain of Holstein bull had no commercially important impact on beef nutritional or eating quality.

Dairy Bulls

The number of male calves from the Irish dairy herd has increased following the abolition of EU milk quotas in 2015. This is a new resource for the industry, and they can be reared economically to produce meat of acceptable eating quality with optimal fatty acid (FA) profile. The effects of breed and feeding treatment on the FA profile of the longissimus thoracis (LT) muscles of young dairy bulls (n = 69) of Holstein–Friesian and Jersey × Holstein–Friesian were evaluated. The relationship between FA composition and sensory characteristics was also investigated. Bulls were offered either 1 or 2 kg of concentrates at pasture during the first grazing season. Bulls finished on silage with 5 kg of concentrates or on ad libitum concentrates were slaughtered at 15 months of age, while bulls slaughtered at 19 months were fed either ad libitum pasture or pasture with 5 kg of concentrates during a second grazing season and finished on pasture with 5 kg of concentrates or ad libitum concentrates. Pasture-finished 19-month-old bulls had higher relative proportions of C18:0 (P &lt; 0.001), C20:5n3 (eicosapentaenoic acid; P &lt; 0.001), C18:2n6c (P &lt; 0.05), C20:4n6 (P &lt; 0.01), and total n-3 (P &lt; 0.001) and n-6 polyunsaturated FAs (P &lt; 0.05), but reduced C14:0, C16:0, C14:1, C16:1 and total monounsaturated FA (P &lt; 0.001) proportions than in other production treatments. The silage-based finishing system of 15-month-old bulls increased the relative proportions of C15:0 (P &lt; 0.01), C18:0 (P &lt; 0.001) and total saturated FA (P &lt; 0.01), but decreased the proportions of C20:3n6 (P &lt; 0.05) and total unsaturated FA (P &lt; 0.01) compared with the ad libitum-concentrate finishing system. However, the feeding system of the first or second grazing seasons had limited effects on the FA profile. Jersey × Holstein–Friesian breed type had higher relative proportions of C14:1 and C16:1 (P &lt; 0.05), but lower C15:0 (P &lt; 0.01), C17:0 (P &lt; 0.001) and C17:1 (P &lt; 0.01) proportions than did Holstein–Friesian beef. Slaughter age did not affect the FA profile. Monounsaturated FA, C14:0 and C16:0 proportions were positively (P &lt; 0.05) correlated, but polyunsaturated FA proportion was negatively (P &lt; 0.05) correlated with intramuscular fat content, sensory roast beef aroma, flavour, flavour length, juiciness, initial tenderness and ease of disintegration scores. Finishing system and slaughter weight were well discriminated on the basis of FA relative proportions by canonical discriminant analysis.

This is an interim, summary and provisional judgment on the Brazilian experiment of the past nine years, that is, since the military took power on April 1, 1964. To try to give an impression of the results of the interaction among the values of political democracy, equality, and economic growth, and the present levels compared with those of 1964 as well as what appear to be the trends. I have chosen six “indicators”:(1)the autonomy and integrity of the legal system;(2)torture and police brutality;(3)freedom of the mass media;(4)income distribution patterns;(5)education distribution patterns; and(6)the quality of life of the people of the city of greater São Paulo.

Cooked Meat

There is anecdotal evidence that certain sheep breeds, reared in a particular way, produce unusual or characteristic tastes in cooked meat. Such effects could be linked to differences in meat fatty acid composition associated with the consumption of different diets. This study investigated eating quality and fat composition in 4 distinctively different breed x feeding system groups.Four groups of 20 ram lambs were obtained as follows: Pure Soays (SO) finished off grass in April from commercial breeders; Pure Welsh Mountain (WM) finished off upland grass in October from ADAS Pwllpeiran; Suffolk x Mules from Harper Adams College finished off concentrates (grains) (SC) in April; and Suffolk x mules from the same source finished off grass (SG) in May. The animals were transported to Langford where they were slaughtered in Bristol University's abattoir.

AbstractThree hundred and eight cattle, comprising steers and heifers from continental and British crosses were finished on an 18-month beef production system at Warren Farm, Lambourn, Berkshire and slaughtered across a range of fatness levels. The eating quality of roasting joints (semimembranosus.) and sirloin steaks (longissimus thoracis et lumborumj was evaluated and the chemical composition of the lean tissue was taken on a subset of the samples. Results suggested that the greatest differences between the breeds was in the joints. There were significant (P < 0·01) differences in the lipid, moisture and collagen contents of the lean tissue of the joints from the different sire breeds. The Belgian Blue sire progeny had significantly lower lipid content than the Charolais or Aberdeen Angus crosses, and significantly lower collagen content than the Aberdeen Angus cross. In addition joints from Belgian Blue crosses were more tender than joints from other breed crosses. Although the lipid and moisture contents of the steaks from different sire crosses were significantly different there was no evidence of differences in eating quality. Perhaps surprisingly there were no significant relationships between the eating quality and chemical composition between or within breed. Irrespective of breed, carcass fatness influenced the juiciness of both the joints and the steaks although the response was different for continental crosses and British crosses and depended on carcass sex. Over and above this response, steer meat was generally more juicy than heifer meat.

World Perspective

Evaluations of mental health services are much in demand. Their results are supposed to help in improving the quality of mental health care and in making them economically better viable.Yet, world-wide there is: 1)little agreement about the content of terms such as evaluation, mental health service, outcome of an activity although these and other terms are widely used;2)uncertainty about the best use of results of evaluative research;3)lack of consensus about who should evaluate what and by what method.

The Cost

The isolation of non pregnant cows in a commercial dairy herd represents a substantial cost to the farmer. The majority of cattle pregnancy diagnoses (PD)'s in the U.K. are made from rectal palpation or by the use of (a) milk progesterone (b) milk oestrone sulphate or ( c) blood progesterone tests. A D.I.Y. pregnancy test has obvious advantages, namely:-1.Tests can be performed by farm stockmen at their own convenience.2.Diagnosis is made immediately.3.Tests can be made through complete pregnancy term.4.After initial capital outlay for equipment, the cost of tests is negligible.Such an alternative is the doppler ultrasound (DOP) system (per rectum) which utilises audible changes in frequency of ultrasound between the transmitted signals and their echoes when moving surfaces are contacted.

SummaryIt is time to improve clinical approaches to faith in mental healthcare, particularly in psychotherapy. Understood as a psychological trait, faith has potentially great personal salience and introduces socially desirable biases into human reasoning. Therapies may have faith-informed components, either explicitly, or (as with some forms of mindfulness) implicitly, which may modify the patient's faith as well as producing symptomatic change. In this narrative review, the ethics of faith's inclusion in therapy is briefly appraised. The psychology of faith is discussed, and a model of the influence of the practitioner's faith on therapeutic choice is presented. Finally, faith-informed approaches to practice, including their impact on therapeutic effectiveness, are considered and recommendations made for their optimal implementation.LEARNING OBJECTIVES•Understand the main types, characteristics and likely effectiveness of faith-informed therapies versus their secular equivalents•Develop a framework for effective assessment of the contribution of faith to a patient's quality of life, and use this to balance the advantages and risks of employing a faith-informed therapy•Be aware of the unavoidability of bias in the assessment of faith, and learn how to minimise this bias, if necessary by making a group decision
