1. Impact of birth weight and daily weight gain during suckling on the weight gain of weaning piglets
RESUMO Objetivou-se avaliar o efeito do peso dos leitões ao nascimento e do seu ganho de peso na maternidade sobre seu desempenho na fase de creche (21-61 dias de idade). Quinhentos e trinta e quatro leitões, provenientes de 55 primíparas, foram pesados ao nascimento, no desmame e na saída da creche. Os animais foram distribuídos em um delineamento inte

2. Oral Administration of Citrus Extracts in Suckling Piglets
Abstract An experiment was conducted to evaluate the performance of suckling piglets subjected to oral administration of citrus extracts (CE). Twenty sows were used with ten sucking piglets on average initial weight of 1.26 kg (± 0.32) for 21 days. The experimental design was a randomized complete block design with two treatments: Negative Control (without

3. Does high stereotypic behavior expression affect productivity measures in sows?
ABSTRACT The objective of this study was to evaluate the effects of stereotypic behavior on productivity measures in sows. Frequent expression of stereotypies by pigs has been reported, even when pigs are not maintained in crates. This behavior is only observed in animals kept in captivity and is a wide-range welfare indicator, since it is considered to deve

4. Induction of puberty and synchronization of estrus in gilts with eCG and GnRH
ABSTRACT In this study, we investigated the effects of eCG and GnRH on the induction of puberty in prepubertal gilts and evaluated the pregnancy rate and litter size in these females. Thirty 140-day-old gilts with an average weight of 80 kg were randomly divided into two treatments: hormonal treatment (n = 15): 1000 IU of eCG and 50 μg of GnRH; and control

5. Arginine improves nutritional quality of sow milk and piglet performance
ABSTRACT 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 so

6. Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestina

7. Neutral detergent fibre in piglet diets: digestibility, performance, and deposition of body nutrients
ABSTRACT A total 120 piglets with an average live weight of 7.00 kg, weaned at 21 days, were used to evaluate the effect of neutral detergent fibre levels on the digestibility of nutrients and energy from the diets, productive performance, and the composition and rate of deposition of nutrients and energy in the bodies of piglets in the nursery phase. The an

8. Impact of piglet birthweight and sow parity on mortality rates, growth performance, and carcass traits in pigs
ABSTRACT A total of 5502 piglets from 435 sows were selected for evaluation of the effect of piglet birthweight and sow parity on mortality rate (MR), growth performance, and carcass traits in pigs. Piglets were distributed into one of eight categories according to their weight (<600, 601-800, 801-1000, 1001-1200, 1201-1400, 1401-1600, 1601-1800, and >1801 g

9. Substitution of blood plasma with soy protein concentrate in piglet diet
ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight

10. Carcass traits and short-chain fatty acid profile in cecal digesta of piglets fed alfalfa hay and fructooligosaccharides
ABSTRACT The objective of this study was to evaluate the effects of the addition of the prebiotic fructooligosaccharide and/or alfalfa hay to piglet diets on carcass traits and short-chain fatty acid profiles in the cecal digesta. Seventy-two commercial crossbred piglets of both sexes, with an average initial weight about 6 kg and age of approximately 21 day

11. Effects of dietary valine:lysine ratios on lactation performance of primiparous sows nursing large litters
ABSTRACT Eighteen sows were used to determine the effect of dietary valine:lysine (val:lys) ratios on lactation performance in primiparous sows and litter performance. Sows, raised in individual pens, were randomly assigned to 1 of 2 experimental diets containing different standardized ileal digestibility (SID) val:lys ratios of 0.80 or 0.85. Corn-soybean-wh

12. Reduction of the crude protein content of diets supplemented with essential amino acids for piglets weighing 15 to 30 kilograms
Two experiments were carried out to evaluate the reduction of crude protein (CP) in diets supplemented with synthetic amino acids for piglets of 15 to 30 kg. In the performance assay (Exp I), 60 piglets with initial weight of 15.34±0.87 kg and final weight of 30.08±1.59 kg were distributed in a randomized block design with six replicates, five treatments a
