Breed Crosses

The study included 201 offspring (108 castrated males and 93 females) of Landrace (L), Large White (LW) and Pietrain (P) sires. The studied animals were of following genotype: Landrace (L; n = 48); two breed crosses with 50:50 share of parental breeds (LWxL, n=32; and PxL, n=23), two breed crosses with 75% of paternal breed [Lx(?LWxL), n=35] and [LWx(?LxWL) n=38] and three breed crosses [Px(?LWxL) n=25]. Animals included in this study were born during four seasons: winter (n=38), spring (n=65), summer (n=40) and autumn (n=58). Studies have shown that, at an average weight of warm carcass side of 81.20 kg, the highest average values for the weight of round (RW; 10.204 kg), the weight of intermuscular fatty tissue (RINT; 0.478 kg), bone tissue (RBT; 0.850 kg) and muscle tissue (RMT, 7.552 kg) in the round, were established in three-breed crosses of Px (LWxL) genotype compared to other genotypes. The least skin and subcutaneous fatty tissue (RST; 1.269 kg) was recorded in two breed crosses PxL. They had less skin and subcutaneous fatty tissue by 454 g and 467 grams, respectively, compared to two breed crosses (LWxL) and LWx (?LxLW). Research has shown that there is a genotype on a farm that gives more muscle tissue in the round by 1.521 kg [Px (?LWxL): LWx (?LWxL)] with the same weight of warm carcass side, which is a very large difference. With the same average weight of warm carcass side, female animals had higher average weight of the round and yield of muscle tissue compared to male castrated animals. The effect of genotype (P<0.001) on all investigated traits was recorded, also the effect of the season of birth on the skin and subcutaneous fat tissue and on the weight of intermuscular fat in the round was recorded. The effect of sex/gender was significant (P<0.01) on the weight of skin and subcutaneous fat and on the weight of the muscle tissues in the round but no significant effect on other tested properties (P> 0.05) was observed.

The study included the progeny of three boar-sires breeds (SL - Swedish Landrace; LW - Large White and P - Pietrain). A total of 201 progeny of both sexes (93 female and 108 male castrated animals), originating from 16 boar-sires, were tested. The study included the progeny of 10 SL boar-sires (sires nuRWer: 1, 2, 3, 7, 8, 9, 15, 16, 17 and 18), progeny of 3 LW sires (sires nuRWer: 4, 5 and 6) and 3 P boar-sires (sires nuRWer 14, 19 and 20), born in four seasons (winter, spring, summer and autumn). Studies have shown that, with an mean weight of a warm carcass side of 81.20 kg, the highest mean values for ham weight (RW; 10.456 kg), mass of intermuscular fatty tissue (RINT; 0.477 kg), ham bone (RB; 0.837 kg) and muscle tissue RMT, 7,939 kg) have progeny of the sires of Pietrain breed (P) compared to SL and LW sires. In comparison to animals sired by SL and LW boars, the progeny of P sires had less skin and subcutaneous fat tissue (RSFT) by 30 and 549 grams. Studies have shown that we have progeny of sires 7 and 9 of SL breed which have the lowest LSMean values for the yield of skin and subcutaneous fat tissue (869 and 876 g), which is below the mean for breed by 364 and 357 g. In addition, when it comes to intermuscular fatty tissue, the lowest established value was recorded in the progeny of sire no. 8 of SL breed (182 g), which is by 220 g less than the general mean and by 132 g below the mean of the sire breed. The animals originating from sires n. 19 and 20 showed the highest weight of muscle tissue (RMT) (8.489 and 8.118 kg) in the ham, which is by 2.853 and 2.482 kg more meat compared to the progeny of sire no. 5 of LW breed. The total weight of the ham and the ham muscle yield were influenced by (P <0.01 and P <0.001) sire breed, sires within the breed, gender and season of birth. A very significant (P <0.001) influence of the weight of warm carcass sides on the ham weight and tissue yield was determined.

SUMMARYThe importance of the different adipose deposits with respect to the total dissectible fatty tissue in growing rabbits and lambs was studied. Development of the subcutaneous fat in the lamb is late and occurs after birth. In contrast, the internal types of fat, such as the perirenal and pelvic fat, represent at birth an important percentage of the total fat. They tend to lose part of their relative importance between 0 and 250 days after birth. In the rabbit the situation concerning the development of subcutaneous and perirenal fat is inverted. For both species the intermuscular fat remains almost constant in relative importance during the whole growth period.After the period required for the establishment of the different fat deposits, we could observe in lambs, and to a smaller degree in rabbits, a relative growth which tends to become isometric with regard to the total fat deposits.

The ARC Nutrient Requirement of Pigs (1981) has highlighted a shortage of information which would allow factorial estimates of chemical body composition to be related to physical carcase composition and commercial grading characteristics. The present study aimed to provide estimates of these relationships.Data related to weights of total carcass lean (Le), total carcass fat (TF), subcutaneous fat (SF), intermuscular fat (IF), total carcass bone (B), whole body crude protein (P), Lipid (Li), Ash (A) and Water (W) and backfat depths (P2, L2, shouTder(sh)) of 231 Newcastle selected (S) and control (C) boars.

Definition Of

(1) Total side fat (total dissected fat plus intramuscular fat) was examined in 23 bovine carcasses in four weight ranges. (2) The partition of fatty tissue between five depots revealed relative rises in intermuscular and subcutaneous depots and relative declines in intramuscular, kidney, and channel fats with increasing carcass weight. (3) Intermuscular and subcutaneous fats reached high levels relative to total side fat at different stages. Intermuscular fat rose quickly to c. 45.0% of total side fat at about 2.0 kg total side fat (c. 56 days) whilst subcutaneous fat reached 29.0% at c. 13.0 kg total side fat (c. 270 days). (4) Intramuscular fat did not show an increase relative to total side fat as carcass weight increased. Its contribution to total fat was greatest in the lightest sides and reached a minimal value at c. 13.0 kg total side fat, which it maintained thereafter. (5) All regressions of the weight of five fat depots on total side fat were highly significant (P < 0.01). (6) There appears to be a need for precise definition of fat distribution patterns in breeds and strains of cattle in order that carcasses of optimum composition might be produced.

ABSTRACTLog-linear relationships between various measurements of the chemical and physical body composition of the pig were obtained in four datasets representing a range of sexes, genotypes and feeding treatments. One of these datasets (dataset 1) comprised genetic control and selection line Large White pigs. There were significant differences between datasets for most of the relationships investigated. The causes of the differences cannot be determined. Within datasets, relationships between various body components and the weight of crude protein in the whole body were unaffected by genotype or sex. The relationships of both intermuscular fat and trimmed carcass lipid with whole body lipid differed significantly between the control and selection lines in dataset 1. Fat thickness measurements taken over the m. longissimus at the last rib were less at the same body lipid in the selection line than the control line suggesting a redistribution of fat away from this area as a result of selection. Relationships between viscera, lungs and empty body weight were significantly affected by line while those between trimmed carcass, liver, kidneys and empty body weight were significantly affected by sex. Selection line pigs had less perinephric and retroperitoneal fat than controls at the same whole body fat weight and less subcutaneous fat at the same cold carcass weight. There were no significant line effects on lean or bone weight distribution. Selection line pigs had significantly less subcutaneous fat in the collar joint and more intermuscular fat in the ham. There were few significant sex effects on tissue weight distribution.

1. The object of the experiment was to make a detailed investigation of the carcass composition of Large White hogs at 68, 91 and 118 kg. live weight (i.e. 50, 68 and 92 kg. carcass weight). Ten hogs were dissected at each stage.2. A dissection technique suitable for this investigation is described, involving the dissection of one side into individual bones and muscles, subcutaneous and intermuscular fat deposits, skin, tendon, glands and blood vessels. Some possible modifications of the method for future investigations are also discussed.3. The complete dissection of one side took approximately 110 man-hours and the average weight loss in dissection was 0·798%.

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is a slowly advancing degenerative disease that mostly affects the cutaneous, subcutaneous fatty tissue, muscle tissue, and bone structures on one side of the face. We describe the chronological progression of this very rare syndrome from early childhood until adulthood in a patient who developed severe atrophy and lost one eye. We also discuss the aetiology and pathophysiology of this syndrome.

Perinephric Fat

1. Investigations on the fats from different tissues of forty-eight Romney ewes have shown that the iodine numbers of the fats cover a wide range from 32·7 for a perinephric fat to 83·7 for the fat from a metacarpal bone, while the percentage fat varies from as low as 3·8 in a longissimus dorsi muscle sample up to as high as 95·5 in a perinephric fat sample.2. The mean iodine values of the fat and percentage fat respectively in the tissues examined were as follows: perinephric, 39·8, 88·1; loin subcutaneous, 41·7, 80·9; loin intermuscular, 44·4, 71·4; longissimus dorsi muscle, 53·1, 7·7; femur, 45·1, 39·8; tibia-tarsus, 54·3, 30·6 and metacarpus, 79·9, 24·3.3. In the carcass tissues the muscle fat was significantly higher in iodine value than the fat from the fatty tissues. In the long bones analysed, the fats from the metacarpus had a highly significantly greater iodine value than was found for the other bones or carcass tissues. The fat from the tibia-tarsus was comparable in iodine value to that of the muscle tissue while the iodine value of the fat from the femur approached that from a fatty tissue.4. A distinctive feature of the fats examined was their variability in iodine value. The values varied between animals by 15·3 units for perinephric fat, by 13·0 units for subcutaneous fat, by 16·9 units for intermuscular fat and by 12·4 units for muscle fat.5. The present results for the iodine values of the fats of Romney ewes generally agree with those obtained by Callow (1958) for Suffolk lambs. However, whereas in Suffolk sheep in accordance with the temperature theory of Henriques & Hansen (1901) the subcutaneous fats have higher iodine values than do the intermuscular fats, in the Romney sheep studied the reverse holds.

Fat Depot

Eighteen Double Muscled (DM), 18 Beef Synthetic (SY) and 18 Hereford (HE) bulls were serially slaughtered from approximately 250 to 800 kg liveweight to determine the influence of maturity type and "double muscling" on fat growth, partitioning and distribution. The fatty tissue was dissected into subcutaneous fat (SCF), intermuscular fat (IMF) and carcass cavity fat (CCF); the sum of these depots was used as total side fat (TSF). Relative to TSF, DM did not differ significantly from the other maturity types in growth rates of SCF, IMF and CCF, but relative to fat percent in the side, DM tended to have much lower growth rates for SCF and CCF. The common growth coefficients indicated that as TSF increased the proportion of SCF increased (b > 1; P < 0.05), the proportion of IMF decreased (b < 1; P < 0.05), and the proportion of CCF remained relatively constant (b = 1; P > 0.05). At equal TSF, as expected, HE tended to partition more of their fat to the subcutaneous depot, whereas DM and SY tended to partition more of their fat to the intermuscular and carcass cavity fat depots. Relative to HE, DM followed late-developing fat partitioning patterns. The hypodevelopment of fat depots in the carcasses of the muscular hypertrophied animals followed an inner-outer gradient which was most pronounced in the subcutaneous fat depot.

Meat Species

There has been recent interest in all the red meat species in a group of compounds known as β-agonists which reduce the proportion of fat in the carcass when added to the diet. In this work the effects of the novel Glaxo compound GAH/034 are reported.Sixty crossbred (Large White x Landrace) gilts from 16 litters were used. From 25 to 80 kg live weight, 2 groups of 10 were fed a control diet (C) containing 13 MJDE and 190g crude protein/kg. Four treatment (T) groups of 10 were fed the same diet containing 4 ppm GAH/034. All groups were fed on the same time-based feeding scale which allowed 1.2 kg/pig/d at 25 kg Increasing by 0.2 kg/d each week to an upper limit of 3.0 kg/day. All pigs were fed the control diet for four days before slaughter at the IFR abattoir at 80 kg live weight after which a range of carcass and meat quality tests were applied. Half the pigs were fully dissected into lean, bone, skin, subcutaneous fat and intermuscular fat.
