“…Although significant differences were observed for pH and lightness at 45 min pm, other meat quality traits such as the ultimate pH, colour at 24 h, drip loss and carcass traits for Treatment EM offspring were unaffected by increased gestational feeding from 25 to 80 dg. This agrees with studies using a similar extended nutritional window (Nissen et al, 2003;Heyer et al, 2004) in which no difference in meat quality traits were seen between treatments. Increased gene expression of PPAR-d in deep and superficial ST, and decreased CAST in ST deep region with no observed phenotypic effect in carcass or meat quality when compared with control, indicate that many cellular factors contribute to phenotype expression.…”

“…Indeed, a larger number of smaller or oxidative fibres can produce more favourable meat quality traits (more intense colour, optimum ultimate pH, less drip loss and improved tenderness of meat; Lengerken et al, 1997;Chang et al, 2003). However, some studies have found that increased maternal nutrition had no beneficial or even negative effects on growth, muscle fibres and meat quality of offspring (Nissen et al, 2003;Heyer et al, 2004). In addition Lawlor et al (2007), observed an increase in the number of piglets born dead due to increased feeding from 50 to 80 dg.…”

Variations in maternal nutrition during gestation can influence foetal growth, foetal development and permanently 'programme' offspring for postnatal life. The objective of this study was to analyse the effect of increased maternal nutrition during different gestation time windows on offspring growth, carcass quality, meat quality and gene expression in skeletal muscle. A total of 64 sows were assigned to the following feeding treatments: a standard control diet at a feed allocation of 2.3 kg/day throughout gestation, increased feed allowance of 4.6 kg/day from 25 to 50 days of gestation (dg), from 50 to 80 dg and from 25 to 80 dg. At weaning, Light, Medium and Heavy pigs of the same gender, within litter, were selected based on birth weight, individually penned and monitored until slaughter at 130 days post weaning. Carcass and meat quality traits of the semimembranosus (SM) muscle were recorded post mortem. A cross section of the semitendinosus (ST) muscle encompassing the deep and superficial regions were harvested from pigs (n 5 18 per treatment) for RNA extraction and quantification of gene expression by real-time PCR. The results showed that doubling the feed intake from 25 to 50 dg reduced offspring growth, carcass weight, intramuscular fat content and increased drip loss of the SM muscle. Interestingly, protein phosphatase 3 catalytic subunit -a-isoform, which codes for the transcription factor calcineurin, was upregulated in the ST muscle of offspring whose mothers received increased feed allowance from 25 to 50 dg. This may provide an explanation for the previous observed increases in Type IIa muscle fibres of these offspring. Increasing the maternal feed intake from 50 to 80 dg negatively impacted pig growth and carcass weight, but produced leaner male pigs. Extending the increased maternal feed intake from 25 to 80 dg had no effect on offspring over the standard control gestation diet. Although intra-litter variation in pig weight is a problem for pig producers, increased maternal feeding offered no improvement throughout life to the lighter birth weight littermates in our study. Indeed, increased maternal nutrition at the three-gestation time windows selected provided no major benefits to the offspring.

“…Evidence from recent studies does not support any impact of increased feed intake in early or mid gestation on piglet birth weight (Heyer et al, 2004;Lawlor et al, 2007). However, increasing feed intake in late gestation has been shown to improve piglet birth weight (Cromwell et al, 1989;Shelton et al, 2009;Soto et al, 2011).…”

“…Increasing energy allowance between days 50 and 80 of gestation even increased the number of stillborn piglets per litter. In addition, Heyer et al (2004) found only marginal effects of increased maternal feed allowance from days 25 to 85 (135%, 170%, 1100%) on the growth, carcass quality and technological meat quality of the offspring. Birth weight and intra-litter variation were not influenced, whereas growth rate was negatively affected in the progeny of second parity sows, but these had higher numbers of weaned piglets.…”

Skeletal muscle development in vertebrates – also termed myogenesis – is a highly integrated process. Evidence to date indicates that the processes are very similar across mammals, poultry and fish, although the timings of the various steps differ considerably. Myogenesis is regulated by the myogenic regulatory factors and consists of two to three distinct phases when different fibre populations appear. The critical times when myogenesis is prone to hormonal or environmental influences depend largely on the developmental stage. One of the main mechanisms for both genetic and environmental effects on muscle fibre development is via the direct action of the growth hormone–insulin-like growth factor (GH–IGF) axis. In mammals and poultry, postnatal growth and function of muscles relate mainly to the hypertrophy of the fibres formed during myogenesis and to their fibre-type composition in terms of metabolic and contractile properties, whereas in fish hyperplasia still plays a major role. Candidate genes that are important in skeletal muscle development, for instance, encode for IGFs and IGF-binding proteins, myosin heavy chain isoforms, troponin T, myosin light chain and others have been identified. In mammals, nutritional supply in utero affects myogenesis and the GH–IGF axis may have an indirect action through the partitioning of nutrients towards the gravid uterus. Impaired myogenesis resulting in low skeletal myofibre numbers is considered one of the main reasons for negative long-term consequences of intrauterine growth retardation. Severe undernutrition in utero due to natural variation in litter or twin-bearing species or insufficient maternal nutrient supply may impair myogenesis and adversely affect carcass quality later in terms of reduced lean and increased fat deposition in the progeny. On the other hand, increases in maternal feed intake above standard requirement seem to have no beneficial effects on the growth of the progeny with myogenesis not or only slightly affected. Initial studies on low and high maternal protein feeding are published. Although there are only a few studies, first results also reveal an influence of nutrition on skeletal muscle development in fish and poultry. Finally, environmental temperature has been identified as a critical factor for growth and development of skeletal muscle in both fish and poultry.
