“…Our results (Table 1) confirm the earlier observations in several different strains of growing chickens (Moss et al, 1964;Mizuno and Hikami, 1971;MacDonald and Swick, 1981). The developmental decrease in the concentration of nucleic acids and the increase in the DNA-unit size have been observed in the skeletal muscles of other strains of chicken as well (Mizuno and Hikami, 1971;Knitzetova et al, 1972;Cornejo et al, 1980). Malhotra and Katoch (1978), however, reported a slight increase in muscle DNA concentration with age in White Leghorn chicks.…”

“…In very young chicks, no significant differences in total DNA or nuclei in a whole muscle exists between slow-growing and fast-growing strains (Moss et al, 1964;Mizuno and Hikami, 1971). As age advances, however, total DNA in fast-growing chicks increases at a faster rate (Table 1) than in slow-growing birds.…”

“…Other mammals tend to follow this trend, although exceptions exist (reviewed by Burleigh, 1980). Data from chicken studies are confusing; for example, Mizuno and Hikami (1971) observed no difference in the total nitrogen:DNA ratio in pectoral muscles of White Leghorn and White Cornish chicks during the first 8 weeks posthatching. However, the gastrocnemius and sartorius muscles of White Cornish chicks have a slightly lower ratio, but only at 8 weeks of age.…”

“…In comparison to the layer-type chicken, the skeletal musculature of the meat-type chicken is characterized by a greater mass composed of more and larger muscle fibers and more DNA (Smith, 1963;Mizuno and Hikami, 1971;Aberle et al, 1979).…”

Growth and Protein Turnover in the Skeletal Muscles of Broiler Chicks

Growth and protein turnover were examined in the breast (pectoralis thoracica) and the leg (gastrocnemius-peroneus) muscles of broiler chicks at 1, 2, 4, and 6 weeks posthatching. The fractional rate of protein synthesis (ks) was measured by an isotope emulsion method. The fractional degradation rate (kd) was calculated from the difference in ks and fractional deposition rate (kg), which was estimated from regression equations of muscle size and protein content on body weights. The growth rate (%/day) of skeletal muscle exceeded that of the whole body. Muscle growth involved an increase in the total deoxyribonucleic acid (DNA) and the DNA-unit size and a subsequent decrease in the concentrations of nucleic acids without alteration in the ribonucleic acid (RNA):DNA ratio and RNA and DNA activity. The ks in breast muscle protein fell markedly from 48 to 16%/day between 1 and 6 weeks posthatching, whereas in leg muscle, ks underwent a more gradual decrease; from 36 to 17%/day during the same period. These changes resulted mainly from the reduction of DNA and RNA concentrations with age. The kd decreased only slightly between 1 and 2 weeks in the both muscle groups. The kg also showed a developmental fall from 33 to 4%/day and from 21 to 4%/day in the breast and leg muscles, respectively, during the 5-week period.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Selection for posthatching muscle growth results in an increase of the embryologically formed myo bre number and of both myo bre length and thickness during the posthatching period (Fowler et al, 1980;Anthony et al, 1988;Soike, 1995). Muscle weight shows close correlations to both myo bre number and size (Moss, 1968;Mizuno and Hikami, 1971;Allen et al, 1979). There are differences in the growth rate of the different bre types (Swatland, 1981;Iwamoto et al, 1993;Gille et al, 1998), but presumably none in the principal growth pattern (Gille et al, 1998).…”

1. Increases in weight of the M. pectoralis, M. iliotibialis lateralis and M. flexor cruris lateralis were measured in mallards, White Pekins, Muscovies and a Muscovy x White Pekin cross from hatching to 154 days of age. Growth with respect to age was analysed using the Janoschek growth curve. 2. The M. pectoralis was less developed at hatching than both leg muscles. Furthermore, it showed a slower growth to its final weight and a later age at maximum growth than both leg muscles. 3. Pekins exhibited a faster Pectoralis and Iliotibialis lateralis muscle growth than mallards and Muscovies. The latter attained greater weights than Pekins at later ages owing to a higher asymptote. The cross showed the fastest muscle growth. 4. With respect to body weight, the Pectoralis is characterised by isometry followed by strongly positive allometry. This multiphasic allometry implies that relative muscle weights should not be used and the value of the allometric exponent strongly depends on both the beginning and duration of the period of investigation. Leg muscles showed isometric to slightly negative, simple allometry.

Muscle Functional Morphology in Paleobiology: The Past, Present, and Future of “Paleomyology”

Our knowledge of muscle anatomy and physiology in vertebrates has increased dramatically over the last two-hundred years. Today, much is understood about how muscles contract and about the functional meaning of muscular variation at multiple scales. Progress in muscle anatomy has profited from the availability of broad comparative samples, advances in microscopy have permitted comparisons at increasingly finer scales, and progress in muscle physiology has profited from many carefully designed and executed experiments. Several avenues of future work are promising. In particular, muscle ontogeny (growth and development) is poorly understood for many vertebrate groups. We consider which types of advances in muscle functional morphology are of use to paleobiologists. These are only a modest subset for muscle anatomy and a very small subset for muscle physiology. The relationship between muscle and bone - spatially and mechanically-is critical to any future advances in "paleomyology". Anat Rec, 301:538-555, 2018. © 2018 Wiley Periodicals, Inc.
