Production and carcass quality of ten beef cattle breeds of the southwest of Europe

A sample of about 70 young bulls of each of ten beef cattle breeds reared in their typical production systems has been studied regarding growth and carcass quality traits. Breeds included were Asturiana de los Valles (AV), Asturiana de la Montaña (AM), Avileña-Negra Ibérica (A-NI), Bruna dels Pirineus (BP), Morucha (Mo), Pirenaica (Pi) and Retinta (Re) from Spain, and Aubrac (Au), Gasconne (Ga) and Salers (Sal) from France. There existed large differences between breeds and also within breeds. AV and Pi were the breeds with more muscle and less fat, whereas A-NI, Mo and Re were in the opposite side. BP and AM occupied an intermediate position. This allows to classify the Spanish breeds in three groups: AV and Pi would belong to the group of late maturity, A-NI, Mo and Re, would be early maturing breeds, whereas BP and AM, despite the small size of the last, will be of intermediate maturity. In the French populations, Au was the breed with the highest carcass weight and Ga exhibited the lowest. Sal occupied an intermediate position, showing the longer and thinner thigh. In a wide range of carcass weight, the general relationships among carcass traits have been confirmed. Animals with the better conformation were also the leaner and longer carcasses tended to be lowly associated with a poorer conformation and fatter carcasses. Bone content was clearly opposed to carcass conformation and muscle content and was associated with longer carcasses

Meat quality of ten cattle breeds of the Southwest of Europe

A sample of about 70 young bulls of each of ten beef cattle breeds reared in their typical production systems has been characterised with respect to meat quality traits. Breeds included were Asturiana de los Valles, Asturiana de la Montaña, Avileña-Negra Ibérica, Bruna dels Pirineus, Morucha, Pirenaica and Retinta from Spain, and Aubrac, Gasconne and Salers from France. As was previously showed regarding carcass traits, there exist large differences both between and within breed – systems. In general, rustic breeds tended to present darker and redder meats with higher haematin contents, whereas less precocious and more specialised breeds showed brighter meats with bigger water losses. Protein content was similar, whereas intramuscular fat presented the larger variations both between and within breeds. ICDH content was higher in the more rustic breeds, showing the predominantly oxidative character of their fibres. Texture measurements showed in general large within breed-system variations, the differences between breeds being less evident. Within breed-system, daily gain weight was positively associated with brighter and tender meats. In the range studied, increasing slaughter weight within breed did not have influence on meat quality. Conformation was related to lower water holding capacity and less dry matter and intramuscular fat, as well as to a lower haematin content giving brighter meats. The increase in fatness scores was related to an augment of toughness in meat specialised breeds, although in Avileña-Negra Ibérica breed fatness carcasses were related to more tender meats. Redness parameter a* was positively related to fatter animals and opposed to conformation, the opposite being true for the L* (lightness) parameter. There was a small trend of fatter carcasses to be related to oxidative fibres, whereas the muscular fibres of the more conformed carcasses were more glycolytic. Texture measurements maximum load, maximum stress and toughness were very closely related. Shear force was opposed to tenderness. Losses at cooking were opposed to juiciness, but only in the Spanish breeds. No consistent trends regarding relationships between carcass characteristics and tenderness could be observed. Overall acceptability was primarily related with tenderness and flavour, and later on juiciness.

Acceptabilitat de la carn de boví uruguaià procedents de diferents sistemes d’alimentació pels consumidors espanyols

L’objectiu principal del projecte és avaluar l'acceptabilitat global, de la tendresa i del gust de la carn de vacum de l’Uruguai per part dels consumidors espanyols. També es va pretendre veure la influència de les característiques dels consumidors (edat, sexe i nivell d'estudis) sobre l'acceptabilitat d'aquesta carn

Projecte d’ampliació i millores de l’explotació bovina de cria “CAN PEREAULET” de Bescanó

L’explotació ramadera a projectar és la “Can Pereaulet”, situada a la finca Can Pereaulet, situada al terme municipal de Bescanó, a la comarca del Gironès, manté una estructura d’àmbit familiar.L’objectiu d’aquest projecte és ampliar la capacitat de la granja Can Pereaulet per poder deslletar els vedells, millorar el benestar animal i la producció de vedells per a engreix a 600 vedells/any. La construcció de la nau permetrà una zona d’alimentació i descans totalment coberta, una zona d’exercici parcialment coberta i una sala de preparació i magatzem dels productes necessaris. De la granja actual s’utilitzarà una quadre per infermeria i la resta per diferents necessitats com ara, magatzem palla, garatge tractor

Projecte d’una explotació bovina d’aptitud càrnia en règim extensiu a “ Can Gummà” de Cabanelles (Alt Empordà)

L’objectiu del projecte és determinar la viabilitat i el rendiment de la instauració d’una explotació bovina d’aptitud càrnia en règim extensiu, aconseguint uns bons nivells de producció i qualitat de la carn. Així mateix i com a complement a l’activitat prevista, es projecta la construcció d’un cobert agrícola de 300 m2 per a emmagatzemar palla i farratges. La finca “Mas Gummà” es troba situada dins terme municipal de Cabanelles, comarca de l’ Alt Empordà, província de Girona. Actualment es dedica a l’agricultura i a la producció ramadera. Pel que fa a la producció agrícola es dedica a la sembra de colza, blat i ordi amb l’objectiu de comercialitzar el gra. Referent a part ramadera es dedica a l’engreix de pocs i a la recria de gallines, en ambdós casos de forma integrada. La finca disposa de 111,23 hectàrees de bosc i de 88,34 hectàrees de terra, incloent la pròpia i l’arrendada

Projecte de gestió conjunta de dos ramats de boví de carn a Borredà (Berguedà)

Disseny de dues explotacions de boví de carn, que actuaran com a una única explotació a nivell sanitari i a nivell de maneig. Es farà un estudi de viabilitat de diferents alternatives a nivell de maneig, tant del bestiar com dels camps, de comercialització, de races, d’alimentació i d’estructures productives. Així mateix i com a complement a l’activitat prevista, es projecta la construcció d’un cobert amb cornadís per alimentar les vaques. Les dues explotacions estan registrades a les finques “El Coll” i “Subirà”, confrontants dins el terme municipal de Borredà (Berguedà). A més d’ambdues finques, la ramaderia consta de més finques situades en municipis de la mateixa comarca, de comarques veïnes i d’una finca de regadiu a Salt (Gironès)
