Colostrum enhances the nutritional stimulation of vital organ protein synthesis in neonatal pigs
The Journal of nutrition, 1997
Our objective was to determine the relative importance of the macronutrient components of colostrum in the stimulation of vital organ protein synthesis in neonatal pigs. We studied colostrum-deprived newborn pigs within 4-6 h after birth (unfed) and three groups fed for 24 h mature milk, colostrum, or a formula containing a macronutrient composition comparable to that of colostrum. We measured protein synthesis in vivo using a flooding dose of 3H-phenylalanine. The fractional rates of protein synthesis (Ks) in the brain, heart, lung, kidney and spleen were significantly higher in all fed groups than in the unfed newborns. Among the three fed groups, brain and heart protein synthesis rates were greater in colostrum-fed than in either milk- or formula-fed pigs. Kidney and spleen protein synthesis rates in colostrum- and formula-fed pigs were not significantly different, but both were higher than in milk-fed pigs. The stimulation of kidney protein synthesis in response to feeding was p...
Performance of low birth-weight piglets upon protein-energy and/or colostrum supplementation
Arquivo Brasileiro de Medicina Veterinária e Zootecnia
The study aimed to investigate the effect of oral protein-energy supplement (OPES) and/or extra colostrum within the first few hours of life on the survival and growth performance of low birth-weight piglets during the suckling period. Based upon nutritional strategy, low-birth-weight piglets (804−1309g) were randomly allocated into four groups: C0S0 (control group, n= 300) - no supplementation; C1S0 (n= 299) - supplementation with 50mL of a colostrum pool through an orogastric tube; C0S1 (n= 298) - oral supplementation with 8mL oral OPES; C1S1 (n= 297) - supplementation with both 50mL of colostrum and 8mL of OPES. The piglets’ body weight was monitored at birth, 24h after birth, on day 7, day 14 and day 20 post-partum. Both colostrum and protein-energy supplementations did not affect (P>0.05) colostrum intake (253.6g; 259.4g; 259.4g; 263.8g for C0S0, C1S0, C0S1, C1S1, respectively), weight gain during the first 24h (62.6g; 68.3g; 67.1g and 69.8g for C0S0, C1S0, C0S1, C1S1, respe...

We hypothesized that nonnutrient components, including growth factors, present in colostrum contribute to the stimulation of protein synthesis in colostrum-fed neonatal pigs. We studied neonatal pigs fed mature milk, colostrum, or a formula containing a macronutrient composition comparable to that of colostrum for 24 h. We measured the circulating concentrations of insulin. insulin-like growth factor L glucose, and amino acids at inteIVals throughout the 24-h period. after which we measured in \'i1'O protein synthesis using a flooding dose of [3H]phenylalanine. The rates of protein synthesis in several tissues measured after 24 h of feeding were greater than those we reported previously after 6 h of feeding. The acute (within 6 h) stimulation of protein synthesis in visceral and skeletal muscle tissues of neonatal pigs fed milk. colostrum. or formula was primar ily influenced by nutrient intake and associated with rapid secretion
An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for 2 h allowing only the SP piglets free access to teats (SPLIT); oral supplementation with 15 ml of sow colostrum to the SP piglets of the litter (COL); and oral supplementation with 3 ml of an energy product (Calostrene®) to the SP piglets of the litter (EN). Thirty-nine primiparous sows (Large White × Landrace) and their litters (507 piglets) and 100 multiparous sows and their litters (1,375 piglets) were used. Litters were fixed at 12 piglets. Piglets were weighed through lactation. Mortality was recorded. For primi-parous sows, oral supplementation with COL enhanced SP piglets bodyweight (BW) at day 1 compared to CON, SPLIT, and EN. However, no differences on BW were observed at day 18 nor on litter total pre-weaning mortality. Nonetheless, lower SP piglets' mortality rate was found in CON and EN compared to SPLIT and COL groups in primiparous sows. For multiparous sows, no differences among treatments were observed for SP piglets BW at day 1 or at day 18. Primiparous sows' SP piglets had higher BW at day 1 than multiparous sows' SP piglets. Colostrum supplementation of low birth weight piglets improved early weight gain in piglets born from primiparous sows, probably by enhancing their colostrum intake, but it did not affect piglets' weaning BW or pre-weaning mortality.
Bovine colostrum as a natural growth promoter for newly weaned piglets: a review
2008
The aim of this review is to present the potential of bovine colostrum as growth promoter in piglet-weaner diet. The main consequence of weaning the piglet is a critical period of underfeeding of which results in the so-called "weaning growth check". Near this reduction in feed intake and growth performance, the gastro-intestinal tract and the immune system of the animal are also affected. Bovine colostrum can be used to reduce the impact of weaning by the action of its bioactive components which may be classified in two classes: the growth factors, which promote the growth and development of the newborn, and the antimicrobial factors, which provide passive immunity and protect against infection. Studies using bovine colostrum in the weaning diet showed increased growth performance and feed intake the first week post-weaning, moreover, a better feed efficiency was also reported, suggesting that the growth benefits attributed to the bovine colostrum supplementation is not due solely to the increased feed consumption. Effects were also observed on the intestinal tract (gastric pH, mucosa restoration, intestinal microflora, local immunisation) but the systemic immune responses were not altered.

The present study investigated the effect of 3 different durations of feeding a diet supplemented with defatted bovine colostrum (Col) on growth performance and sanitary status of the weaned piglet. At 28 d of age, piglets were weaned and fed 1 of the 2 following diets: a control (Ctrl) starter diet or a starter diet supplemented with Col. Two experiments were conducted. In Exp. 1, 310 piglets (12 pens consisting of 10 piglets/pen and 10 pens consisting of 19 piglets/pen) were allocated to 1 of the 2 dietary treatments for 12 d. In Exp. 2, 522 piglets (18 pens consisting of 10 piglets/pen and 18 pens consisting of 19 piglets/pen) were allocated to 1 of the following 3 dietary treatments: fed the Ctrl diet from d 1 to 12 (Ctrl), Col diet from d 1 to 4 and then the Ctrl diet up to d 12 (Col-4d), or the Col diet from d 1 to 6 and then the Ctrl diet up to d 12 (Col-6d). For both experiments, a commercial second-phase diet was fed to piglets from d 12 to 46. Feed intake, growth performance, and cleanliness of fl oor and hindquarters of animals were investigated during the fi rst 7 wk postweaning. In Exp.
