“…Also Liotta et al . (), during their initial investigations on a native Italian Nero Siciliano swine breed reported that the level of fat in the colostrum and milk of sows varied and reached the highest percentage value of 8.68 in the first period of lactation. Experiments carried out by Beyga and Rekiel () on hybrids of commercial breeds (Polish Large White × Polish Landrace) in which they investigated fat content in sows' milk showed that the level of fat increased together with the progress of lactation reaching the value of 6.4%.…”

The aim of this study was to evaluate the effect of the level of fat and selected fatty acids found in the milk of sows on the rearing of native breed piglets. Simultaneously, in order to improve the accuracy of the performed analyses, atomic absorption spectrometry was employed in the applied analytic methodology. The experimental animal material comprised 60 sows of the indigenous White Złotnicka breed. Colostrum and milk were collected on the first and 14th days of lactation. In all, 240 samples were collected. The following parameters were determined in the course of the experiment: number and weight of piglets, body weight gains as well as deaths of piglets. A total of 1270 born piglets was subjected to investigations. The performed experiments demonstrated that, with the progress of the lactation period, the content of fat and saturated fatty acids (SFA) turned out to be statistically significant and showed a growing tendency. Fat increased by about 2% and palmitic acid (C16:0) increased most, that is by 5%. Linolic (C18:2) and linolenic (C18:3) acids revealed decreasing trends. Irrespective of the day of lactation, the level of unsaturated fatty acids (UFA) determined in sows' colostrum and milk was higher in comparison with that of SFA, and the UFA to SFA ratio ranged from 1.84% to 1.33%. Proportions of n-6 to n-3 fatty acids were determined at the level of about 1.6:1.0 in the colostrum and 1.3:10 in milk. The highest daily body weight gains were recorded in the case of piglets derived from sows with the highest fat level – 294 g, while in the case of stearic acid (C18:0), the smaller its concentration in the colostrum and milk of the experimental sows, the better body weight gains of piglets – 262 g. At the same time, stearic acid (C18:0) was found to exert a statistically significant effect on piglet mortality at the level of P ≤ 0.05. Its highest concentration caused the highest proportion of deaths among piglets - 16.23%. The performed analysis of correlations that occurred between fat, fatty acids and traits associated with piglet rearing confirmed that linolic acid (C18:2; n-6) was highly significantly correlated with piglets' body weights (r = 0.456**) and was negatively correlated with piglets' deaths (r = −0.312). On the other hand, fat revealed correlation with body weight gains of piglets (r = 0.333*_ and a negative correlation with deaths of piglets (r = −0344*). Recapitulating, the results of the performed experiments revealed that differences in the levels of fat and fatty acids found in sows' colostrum and milk influenced results of piglet rearing. Together with the increase in the content of fat and UFA in sows' colostrum and milk, piglets were characterized by the best body weight, growth rate, as well as by small mortality.

“…Nevertheless, compared with Braude et al (1947), working with Large White sows, the present results show consistently Nutrient balance in suckling Iberian piglets lower concentrations for total solids, fat and protein and a higher lactose content. According to Liotta et al (2007), the milk from Nero Siciliano sows, a Mediterranean pig genotype like the IB breed, have greater concentrations of fat and energy than IB milk does.…”

Sixteen purebred Iberian (IB) sows were used in two consecutive trials to determine the efficiency of conversion of sow's milk into piglet body weight (BW) gain and the relationship between milk protein and body protein retention and between milk energy yield and body energy retention in the nursing IB piglet. In each trial, four sows were selected in order to evaluate their milk production, litter growth and nutrient balance measurements, together with four additional sows for milk sampling. Litter size was equalized to six piglets. Daily milk yield (MY) was determined weekly by the weigh-suckle-weigh technique over a 34-day lactation period. Piglets were weighed individually at birth and then weekly from day 5 of lactation. Milk samples were collected on days 5, 12, 19, 26 and 34 post partum. The comparative slaughter procedure was used to determine piglet nutrient and energy retention. One piglet from each litter was slaughtered at birth and four on the morning of day 35. Total MY was on average 5.175 6 0.157 kg/day. The average chemical composition (g/kg) of the milk was 179 6 4 dry matter, 53.4 6 1.0 CP, 58.5 6 3.8 fat, 10.4 6 0.3 ash and 56.9 6 2.3 lactose. Milk gross energy (GE) was 4.626 6 0.145 MJ/kg. Milk intake per piglet tended to increase in trial 2 (832 v. 893 g/day; P 5 0.066). Piglet BW gain contained (g/kg) 172.1 6 1.3 protein, 151.5 6 3.5 fat, 41.4 6 0.6 ash and 635 6 3 water and 10.127 6 0.126 MJ GE/kg. Throughout the 34-day nursing period, the piglets grew at an average rate of 168 6 3 g/day. The ratio of daily piglet BW gain to daily MY was 0.195 6 0.002 g/g and the gain per MJ milk GE intake was 41.9 6 0.5 g/MJ. The overall efficiency of protein accretion (g CP gain/g CP milk intake) was low and declined in trial 2 (0.619 v. 0.571; P 5 0.016). Nutrient and energy deposition between birth and weaning were 27.4 6 0.5 g/day protein, 24.2 6 0.8 g/day fat and 1615 6 40 kJ/day energy. Piglet energy requirements for maintenance were 404 kJ metabolizable energy (ME)/kg BW 0.75 . ME was used for growth with a net efficiency of 0.584. These results suggest that poor efficiency in the use of sow's milk nutrients rather than a shortage in milk nutrient supply might explain the low growth rate of the suckling IB piglet.Keywords: milk production, milk composition, Iberian piglets, protein and energy deposition, nutrient balance ImplicationsThis study suggests that growth rate in the suckling Iberian (IB) piglet is not limited by a shortage in milk nutrient supply but might rather be related to a very low efficiency in the use of milk protein and energy. In the young IB piglet, protein deposition is a costly process, presumably because of a high protein turnover rate, as found in later growth stages. The sharp decrease in milk conversion ratios detected during the last week of the study implies that a lactation period of more than 4 weeks is not to be recommended.
