Effects of breed and sex on foetal development.

<p>Mean ± S.E.M. measurements and weights of Iberian purebred and lean crossbreed foetuses and selected organs.</p><p>Different letter in superscripts indicate significant differences between breeds (a≠b, p<0.05; c≠d, p<0.01; e≠f, p<0.005; g≠h, p<0.001; i≠j, p<0.0005) whilst different number denotes significant differences between sexes within the same breed (1≠2, p<0.05; 3≠4, p<0.01; 5≠6, p<0.005).</p

Effects of breed on the relative development of foetuses and their organs.

<p>Mean ± S.E.M. ratios of head weight to total body weight (A), of individual weight of selected organs to total body weight (B) and of brain weight to the weights of total viscera and selected organs (C) in Iberian purebred (black bars) and lean crossbreed foetuses (white bars). Asterisk indicate significant differences between breeds (* = p<0.05, ** = p<0.01, *** = p<0.005, **** = p<0.001, ***** = p<0.0005).</p

Effect of breed and sex on parameters related to lipids metabolism.

<p>Mean ± S.E.M. concentrations of triglycerides, total cholesterol, high-density lipoproteins cholesterol [HDL-c] and low-density lipoproteins cholesterol [LDL-c] in plasma and allantoic and amniotic fluids of Iberian purebred and lean crossbreed foetuses.</p><p>Different letter in superscripts indicate significant differences between breeds (a≠b, p<0.05; c≠d, p<0.01; e≠f, p<0.005; g≠h, p<0.001; i≠j, p<0.0005). Different number in superscripts indicate significant differences between sexes within the same breed (1≠2, p<0.05; 3≠4, p<0.01; 5≠6, p<0.005).</p
