The effect of different physical forms of starter feed on rumen fermentation indicators and weight gain in calves after weaning. Full Text Available The aim of the study was to determine the effect of different physical forms of starter feed on rumen fermentation indicators of calves after weaning and their weight gain. The experiment was performed with Czech Fleckvieh calves after weaning.
The calves were fed ad libitum completely pelleted starter feed or texturized starter feed with chopped straw. The rumen fluid samples were collected after a month of feeding the starter feeds. The calves were weighed monthly. The pH, total acidity, total volatile fatty acids, acetate, propionate, butyrate, lactic acid, ammonia and the number of rumen ciliate protozoa were determined in the rumen fluid samples.
The calves receiving the starter feed with straw showed significantly higher rumen pH 6. Average daily gain of the calves did not differ significantly. The feeding of starter feed with chopped straw compared with the pelleted starter feed led to better development of the rumen fermentation evaluated by rumen pH, by total volatile fatty acids production, and by the proportion and ratio of acetic and propionic acids.
The feeding of starter feed with chopped straw reduced the occurrence of subacute ruminal acidosis in the weaned calves. The age of months is important because it is transition from liquid to solid foods. A purely breast milk diet is unsufficient to meet the nutritional needs of a fast growing baby growth. Weaning diet for baby is necessary to prevent growth disorder.
The aim of the study was to assess the effect of weaning diet on weight gain of month infant in posyandu intergrated health center of Kutoharjo Kaliwungu Kendal. The study was an analytic observational study with a cross sectional design.enter site

The informations of weaning diet was obtained by questionare and interview. The results classified the baby into two groups namely the appropiate groups and inappropriate groups. Data were analyzed by Chi-Square Test. While of 36 The Chi-Square analysis showed p-value of 0. Estimating non-genetic and genetic parameters of pre- weaning growth traits in Raini Cashmere goat.
Data and pedigree information used in the present study were 3, records of kids obtained from the breeding station of Raini goat. The model included the fixed effects of sex of kid, type of birth, age of dam, year of birth, month of birth, and age of kid days as covariate that had significant effects, and random effects direct additive genetic, maternal additive genetic, maternal permanent environmental effects and residual.
Co variance components were estimated using univariate and multivariate analysis by WOMBAT software applying four animal models including and ignoring maternal effects. Likelihood ratio test used to determine the most appropriate models. Estimates of the proportion of maternal permanent environmental effect to phenotypic variance c 2 were 0. Genetic correlations among traits were positive and ranged from 0. Results indicated that maternal effects, especially maternal permanent environmental effects are an important source of variation in pre- weaning growth trait and ignoring those in the model redound incorrect genetic evaluation of kids.
Age and body weight effects on glucose and insulin tolerance in colony cats maintained since weaning on high dietary carbohydrate. High dietary carbohydrate is suggested to promote development of diabetes mellitus in cats. Glucose tolerance, insulin sensitivity, and insulin secretion were assessed in young [0. Insulin sensitivity was assessed from the 'late-phase' min plasma insulin response of intravenous glucose tolerance tests IVGTTs and from fractional change in glycaemia from baseline 15 min after an insulin bolus 0.
Compared to the young cats, the mature cats had greater body weights [2. The findings indicate that body weight gain is more likely than dry-type diets to induce the pre-diabetic conditions of insulin resistance and secretion dysfunction. Genetic analysis of body weight in South African Angora kids and Variance and covariance components and ratios pertaining to direct additive genetic variation, maternal additive genetic variation, maternal permanent environmental variation, and the relationship between direct and maternal effects for birth weight BW; kg , weaning weight WW ; kg and body weight at 8, 12 and A divergent Artiodactyl MYADM-like repeat is associated with erythrocyte traits and weight of lamb weaned in domestic sheep.

MYADM gene family members play roles in membrane organization and formation in myeloid cells. The specific RBC differences may be indicative of alterations in morphology. Additionally, erythrocytes with altered morphological structure often exhibit increased structural fragility, leading to increased RBC turnover and energy expenditure. This suggests selection for normal RBCs might increase lamb weights , although further validation is required before implementation in marker-assisted selection.
This glucose amount may be the minimum requirement of exogenous glucose for reducing weight gain. Environmental factors that influence milk production of Pantaneiro ewes and the weight gain of their lambs during the pre- weaning period. The main objective of this research was to conduct an exploratory study of the lactation curve in order to characterize the productive potential of Pantaneiro ewes and lambs. Fifty ewes were bred using four rams in two different mating seasons. The ewes were kept with their lambs on pasture of Brachiaria brizantha. Ewe body score, ewe weight , and lamb weight were evaluated.
Milk sampling was performed every week. In the morning for milk collections, the ewes were treated with 1 UI of oxytocin intramuscular for complete milking. Ewe body score at lambing affected initial milk production 1. Lambs were weaned with an average weight of Locally adapted Pantaneiro ewes showed a linear decreasing lactation curve, with reduced production from the second week of lactation.
Overall, evaluation of the dairy production and lamb performance revealed great variation, denoting potential for selection.
The effect of creep feeding on average daily gain ADG and weaning weight WW of calves and pregnancy rate of dams was evaluated in Nelore cattle on Brachiaria Brizantha pasture. The primiparous cows were in low body condition at beginning of breeding season.

Average daily consumption of the creep ration was 0. WW averaged Thus, creep feeding can improve WW and preweaning ADG of Nelore calves but may not affect pregnancy rate of primiparous cows in low body condition at the start of the mating. Tyrosine phosphorylation of WW proteins. A number of key regulatory proteins contain one or two copies of the WW domain known to mediate protein—protein interaction via proline-rich motifs, such as PPxY.
The Hippo pathway components take advantage of this module to transduce tumor suppressor signaling. It is becoming evident that tyrosine phosphorylation is a critical regulator of the WW proteins. Here, we review the current knowledge on the involved tyrosine kinases and their roles in regulating the WW proteins. Testing post- weaning food motivation in low and normal birth weight pigs in a runway and operant conditioning task.
Understanding the underlying mechanisms of cognitive and learning abilities in these pigs may help to improve their welfare. Early competition in life over resources, combined with the higher need. Early competition in life over resources, combined with the higher. Supplementation of dextrose to the diet during the weaning to estrus interval affects subsequent variation in within-litter piglet birth weight.
Effects of supplementation of dextrose to the diet of sows during the weaning -to-estrus interval WEI on subsequent litter size and within-litter variation were investigated. After weaning , sows first to fifth parity were fed 3. Half of the sows additionally received g of dextrose.
The effect of herd of origin by year on post- weaning traits of young Data consisted of post- weaning traits of beef bulls tested between and , with available weaning weight WWT and weaning management group information as well as weaning weights of their contemporaries. Altered gut microbiota in female mice with persistent low body weights following removal of post- weaning chronic dietary restriction.
Nutritional interventions often fail to prevent growth failure in childhood and adolescent malnutrition and the mechanisms remain unclear.
