“…The changes in milk composition on the days of evaluation were consistent with several other studies (Daza et al, 2004;Aguinaga et al, 2011;Wang et al, 2013) that observed a reduction in the nutritional quality of milk as lactation progressed.…”

The objective of this study was to evaluate the effect of L-arginine supplementation in lactation diets on the productive and reproductive performance of pluriparous sows and their litters. Seventy-six sows of the same genetic line were assigned to four treatments in a completely randomized design with 19 replicates. The experimental unit was the sow and its respective litter. Treatments comprised a control diet (no L-arginine supplementation) and other three diets obtained by top dressing the control diet with 0.5, 1.0, and 1.5% of L-arginine. L-arginine supplementation had no effect on any performance variables, body condition, milk production, or weaning-estrus interval. There was a quadratic effect on percentage of protein and fat in milk as well as on the daily production of these components. Protein and fat percentage declined during lactation. Adding L-arginine to the diet had a quadratic effect on piglet weight at 13 and 21 days, the optimal level of L-arginine supplementation being estimated as 0.64% and 0.71%, respectively. L-arginine supplementation had a quadratic effect on the weight gain of piglets during the first 13 days and on total period of lactation, the optimal level of L-arginine supplementation being estimated as 0.60% and 0.70%, respectively. Supplementing lactation diets with 0.70% of L-arginine, corresponding to 45 g day −1 , improves the weight gain of piglets by improving the nutritional quality of sow milk.

The study aimed to investigate the possible anti-inflammatory activity of larch sawdust as feed supplement in lactating sows' diet and its possible effect on the prevalence of Postpartum Dysgalactia Syndrome under field conditions. In a Greek farrow-to-finish pig farm, fifteen sows were randomly and equally allocated to a negative control group (NC group), a positive control group (PC group), and a treatment group (LT group). The animals of the first two groups received 99% basic diet and 1% corn starch, while LT group animals received 99% basic diet and 1% larch sawdust. The whole trial period lasted 35 days (7 days prior to farrow -day of weaning). At parturition day, animals of the PC group received 2 ml of an anti-inflammatory drug intramuscularly (meloxicam, Metacam ® , Boehringer Ingelheim Vetmedica), while the animals of both other groups, received 2 ml of normal saline. Results showed insignificant differences among experimental groups for parameters such as post-partum rectal temperature and piglets performance. On the contrary, a significant increase of mean milk lactation index was observed in LT and PC groups on the 4th day of lactation period, when compared with NC group (p=0.014). Additionally, mean IL-6 concentrations in blood in the LT group showed a tendency for reduction when compared with those found in NC, and insignificant difference (p>0.05) when compared with those observed in PC group 24 hours postpartum. Moreover, the respective TNFα mean level in the LT group at 24 and 72 hours after parturition was similar to that found in PC group, respectively) and significantly lower than that determined in the NC group (p=0.003, p=0.024. The results suggest a possible anti-inflammatory effect of larch sawdust in sows.

“…Therefore, EAAIsow's milk of colostrum samples were calculated as well with formulas, where the protein of sow's milk was used as standard protein. An average concentration of essential amino acids in sow's milk was calculated from results published by Elliott et al (1971), Csapó et al (1996), Dourmad et al (1998), Daza et al (2004), Petrikovič et al (2005).…”

“…For example, Dourmad et al (1998) took milk samples for amino acids determination after injecting of oxytocin at day 3, 7, 15 and 22 of lactation. Daza et al (2004) milked functional glands of sows after injecting of oxytocin on day 5, 12, 19 and 26 of lactation. Dunshea et al (2005) collected milk samples from sows in the mid and late lactations stage, without the injection of oxytocin.…”

The aim of this study was to determine the protein quality of sow's colostrum. For this purpose, the essential amino acid index (EAAI) of sow's colostrum was calculated. The study was carried out on 12 Large white sows, which were on the 2.9 farrowing on average. Colostrum samples were collected by milking per hand without application of oxytocin. First sample were milked at time of birth of first piglet, and then every hour till 12 th hour. Essential amino acids were determined using Amino Acid Analyser AAA400 (Ingos, Prague). For calculation of EAAI, the egg protein (EAAIegg) and protein of sow's milk (EAAIsow's milk) were used as standard. The highest value of EAAI was calculated for both at 4 th h, EAAIegg 97.1%, EAAIsow's milk 120.2%. The lowest values of EAAI were calculated at 12 th h EAAIegg 78.3% and EAAIsow's milk 96.9%. During the first 12 hours, protein of sow's colostrum had not reached the quality of egg protein. Except sample collected at 12 th hour after birth of first piglet, all colostrum samples had better quality of protein in comparison to sow's milk. No significant (P>0.05) differences of EAAI between colostrum samples collected at different times from the birth of the first piglet till 12 th h were observed.Keywords: amino acids, colostrum, index of essential amino acid, sow Abstrakt Cieľom tejto práce bolo stanoviť kvalitu bielkovín v mledzive prasníc. Pre dosiahnutie vytýčených cieľov bol pre mledzivo prasníc vypočítaný index esenciálnych aminokyselín (EAAI). Štúdia bola realizovaná na 12 prasniciach plemena Biela ušľachtilá, ktoré boli v priemere na 2,9 vrhu. Vzorky mledziva boli odoberané ručným oddojením, bez aplikácie oxytocínu. Prvá vzorka bola odobraná v čase narodenia prvého prasiatka vo vrhu, následné vzorky boli odoberané každú hodinu až do dvanástej hodiny po narodení prvého prasiatka. Obsah esenciálnych aminokyselín bol stanovený na prístroji Amino Acid Analyser AAA400 (Ingos, Praha). Ako štandardná bielkovina pre výpočet EAAI bola použitá bielkovina vajca (EAAIegg) a bielkovina mlieka prasníc (EAAIsow's milk). Najvyššie hodnoty EAAI boli stanovené pri oboch na 4 hodinu od narodenia prvého prasiatka, EAAIegg 97,1%, EAAIsow's milk Original scientific paper DOI: /10.5513/JCEA01/19.1.2028 Journal of Central European Agriculture, 2018, 19(1), p.95-101 95 120,2%. Najnižšie hodnoty EAAI boli stanovené na dvanástu hodinu od narodenia prvého prasiatka, EAAIegg 78,3% and EAAIsow's milk 96,9%. Počas sledovaných prvých dvanástich hodín mledzivo prasníc nedosiahlo kvalitu bielkovín, ktorá je vo vaječnej bielkovine. Okrem vzorky mledziva odobranej na dvanástu hodinu po narodení prvého prasiatka, mali všetky vzorky mledziva lepšiu kvalitu bielkovín ako je kvalita bielkovín v mlieku prasníc. Rozdiely hodnôt EAAIegg a aj EAAIsow's milk zistené medzi jednotlivými časmi odberu vzorky boli štatisticky nepreukazné (P>0.05).
