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 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...

Body size and its effects on productive efficiency of cows with predominant Nellore genetic composition Animal Sciences
Farias, Gustavo Duarte; Cerdótes, Liliane; Restle, João; Pascoal, Leonir Luiz; Costa, Pablo Tavares; Ferreira, Otoniel Geter Lauz; Vaz, Ricardo Zambarda.
 This study was developed to evaluate productive efficiency during the lactation period of cows with predominant Nellore genetic composition based on their body size. Cows were divided into the following categories: light (≤ 316 kg), moderate (≥ 317 and ≤ 400 kg), or heavy (≥ 401 kg). Body weight change and total gain from birth to 210 days of age of calves born from heavy cows (0.155±0.03 and 111.6±5.1 kg) were higher than those of calves born from light (0.064±0.03 and 91.0±4.3 kg) and moderate (0.144±0.03 and 97.7±4.0 kg) cows. Calf production index differed (p < 0.05) with the herd of heavy cows (93.5±3.2 kg), producing 57.4 and 19.7% more kilograms of calf than light (59.4±2.7 kg) and moderate (78.1±2.4 kg) cows, respectively. Heavy Nellore cows...

Ca2+-activated Cl- channel currents in mammary secretory cells from lactating mouse OAK
Kamikawa, Akihiro; Ichii, Osamu; Sakazaki, Junpei; Ishikawa, Toru.
The Cl- secretion via Ca2+-activated Cl- channel (CaCC) is critical for fluid secretion in exocrine glands like the salivary gland. Also in the mammary gland, it has been hypothesized that CaCC plays an important role in the secretion of Cl- and aqueous phase of milk. However, there has been no evidence for the functional expression of CaCC in native mammary secretory (MS) cells of lactating animals. We therefore assessed membrane current in MS cells that were freshly isolated from lactating mice using whole cell patch-clamp techniques. In MS cells, we detected CaCC current that exhibited the following characteristics: 1) Ca2+-dependent activation at the concentrations of sub-micromolar range; 2) voltage-dependent activation; 3) slow kinetics for...

Developmental and behavioral effects of postnatal amitraz exposure in rats BJMBR
Palermo-Neto,J.; Sakaté,M.; Flório,J.C..
The effects of postnatal amitraz exposure on physical and behavioral parameters were studied in Wistar rats, whose lactating dams received the pesticide (10 mg/kg) orally on days 1, 4, 7, 10, 13, 16 and 19 of lactation; control dams received distilled water (1 ml/kg) on the same days. A total of 18 different litters (9 of them control and 9 experimental) born after a 21-day gestation were used. The results showed that the median effective time (ET50) for fur development, eye opening, testis descent and onset of the startle response were increased in rats postnatally exposed to amitraz (2.7, 15.1, 21.6 and 15.3 days, respectively) compared to those of the control pups (1.8, 14.0, 19.9 and 12.9 days, respectively). The ages of incisor eruption, total...

Zhang,Lian-Dong; Deng,Qian; Wang,Zi-Ming; Gao,Ming; Wang,Lei; Chong,Tie; Li,He-Cheng.
Studies of developmental effects of mixtures of endocrine disrupters on the male reproductive system are of great concern. In this study, the reproductive effects of the co-administration of di-2-(ethylhexyl) phthalate (DEHP) and genistein (GEN) during pregnancy and lactation were studied in male rat offspring. Pregnant Sprague-Dawley rats were gavaged from gestation day 3 to postnatal day 21 with vehicle control, DEHP 250 mg/kg body weight (bwyday, GEN 50 mg/kg bwday, GEN 400 mg/kg bwday, and two combinations of the two compounds (DEHP 250 mg/kg bwday + GEN 50 mg/kg bwday, DEHP 250 mg/kg bwday + GEN 400 mg/kg bwday). The outcomes studied were general morphometry (weight, AGD), testicular histology, testosterone levels, and expression at the mRNA level of...

EFFECT OF CADMIUM ON RAT MAXILLARY MOLAR JUNCTIONAL EPITHELIUM DURING LACTATION: EFECTO DEL CADMIO SOBRE EL EPITELIO DE LA ZONA DE UNIÓN MAXILO-MOLAR DE RATAS DURANTE LA LACTANCIA International Journal of Morphology
Ribas,Paulo; Lopes,Ruberval A.; Sala,Miguel A.; Ribas,Lucia M.R.; de Mattos,Maria da Glória C.; Semprini,Marisa; Watanabe,Ii-Sei; Regalo,Simone C.H..
Cadmium in the air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cadmium affects placental functions, can cross the placental barrier and directly disturbs fetal development. It is also excreted into milk. The organism is particularly susceptible to cadmium exposure at perinatal period. The effect on rat maxillary molar junctional epithelium a continuous exposure to drinking water containing low level of cadmium during lactation was studied. Female rats received drinking water ad libitum containing 300 mg/l CdCl2 throughout the whole lactation. Control animals received a similar volume of water without cadmium. Lactent rats (21 day-old) were killed by lethal dose of...

Effect of feeding Acacia saligna (Labill.) H.L. Wendl. on goats stabled during late pregnancy and lactation Chilean J. Agric. Res.
Meneses R,Raul; Olivares V,Yohana; Martinoli S,Milenko; Flores P,Hugo.
Acacia saligna (Labill.) H.L. Wendl. forage is an alternative feed supply for goats during dry periods It was used as feed during pregnancy and lactation to evaluate production response and some blood parameters. Six animals in each group were fed with 0, 25, 50, 75, and 100% of acacia as alfalfa (Medicago sativa L.) hay replacement in a completely randomized design. Forage chemical analysis was done to calculate nutrient intake. Blood samples were analyzed for albumin, urea N, globulin, total protein, Ca, and P. Productive parameters were analyzed by ANOVA, Duncan, and regression analyses between acacia and dry matter (DM), crude protein (CP), metabolizable energy (ME), and milk production. Acacia consumption during pregnancy was 65.5% of control,...

Effects of ethanol intake on retinol concentration in the milk of lactating rats BJMBR
Albuquerque,K.T.; Ramalho,R.A.; Soares,A.G.; Tavares-do-Carmo,M.G..
The effect of the consumption of ethanol (5%) on retinol concentration in milk was studied in the rat on day 12 after delivery, together with the evolution of dam body weight and pup growth rate. Female Wistar rats receiving alcohol (5%) in drinking water during lactation (N = 7) were compared to normal controls fed ad libitum (N = 6). The mean maternal alcohol intake was 3.96 ± 0.23 g/kg body weight per day. To determine retinol levels in milk we used the Bessey and Lowry method, modified by Araújo and Flores ((1978) Clinical Chemistry, 24: 386-392). The pups were separated from dams for a 2-4-h period, after which the dams were injected intraperitoneally with anesthetic and oxytocin. The concentration of retinol in milk was 162.88 ± 10.60 µg/dl in the...

Effects of Zinc During Lactation on the Junctional Epithelium and Inserted Gum in Rats International Journal of Morphology
Felippini,Ana Luiza de Carvalho; Sala,Miguel Angel; Lopes,Ruberval Armando; Silva,Gilberto André e.
The purpose of this study was to evaluate the effects of zinc, during lactation, on the junctional epithelium and inserted gum of the first upper molar of rats. The study used one-day old male rats, divided into two groups: those whose mother had been treated with 300 mg zinc chloride (ZnCl2) in the drinker water (treated group), and those whose mothers did not receive ZnCl2 (control group). After 21 days, the rat pups were sacrificed. Using karyometrical techniques, the greater (D) and smaller (d) nuclear diameters of the different layers of the junctional and inserted gum epithelia were determined, and the mean geometric diameter, D/d ratio, perimeter, area, volume, volume/area ratio, eccentricity, shape coefficient, and the contour index were estimated....

AZARA,CÍNTIA R.P; MAIA,INGRID C; RANGEL,CAROLINA N; SILVA-NETO,MÁRIO A.C; SERPA,RENATA F.B; DE JESUS,EDGAR F.O; TAVARES  DO CARMO,MARIA G; FIALHO,ELIANE.
Lactating Wistar rats were fed a liquid diet containing either ethanol [ethanol-fed group (EFG)] or an isocaloric amount of carbohydrate [pair-fed group (PFG)] from day 1 postpartum up to day 14 of lactation, to investigate micro/macronutrient milk composition and the mineral status of pups. EFG presented a reduction of daily milk production and milk composition was significantly higher in protein and lower in carbohydrate, while the lipid content was similar to that of PFG. When compared to PFG, the milk of EFG had a decreased proportion of C22:6 n-3 fatty acid and an increase in medium-chain fatty acids and of several minerals. Pups of EFG showed reduced growth and a lower concentration of Cu and Sr in plasma and lower concentrations of Ca, P and Cl, and...

Food intake and weight of lactating rats maintained on different protein-calorie diets, and pup growth BJMBR
Cambraia,R.P.B.; Vannucchi,H.; De-Oliveira,L.M..
Studies on rats maintained on low-protein-calorie diets during the lactation period show that food intake decreases. This process results in weight loss and a delay in litter development. The purpose of the present study was to determine the alterations in food intake, maternal weight and litter growth during lactation when dams were exposed to diets with different levels of protein and carbohydrate. Female Wistar rats receiving one of 4 different diets, A (N = 14), B (N = 14), C (N = 9) and D (N = 9), were used. Diet A contained 16% protein and 66% carbohydrate; diet B, 6% protein and 77% carbohydrate; diet C, 6% protein and 66% carbohydrate; diet D, 16% protein and 56% carbohydrate. Thus, C and D diets were hypocaloric, while A and B were isocaloric. The...
