Early weaning and other methods of intensive lamb production
Early weaning onto pasture, separate grazing for ewes and lambs on pasture, and weaned and nonweaned lambs in a drylot were compared with control groups of ewes and lambs grazed together at Blacksburg and Glade Spring in 1960 and 1961. Data were available on 457 lambs for average daily gain and …

Fetal programming effects of early weaning on subsequent calf performance
… ± 72 kg) were used to evaluate the effects of early weaning on subsequent calf growth performance and carcass characteristics. Cows were assigned to 1 of 2 treatments based on their previous calf’s weaning age: 1) early wean (EW) or 2) conventional wean (CW). The EW treatment had a steer calf …

Utilization of early weaning and intrafollicular insemination as methods to improve the reproductive performance of cattle
… to test the reproductive outcomes following early weaning of beef heifers and intrafollicular insemination in dairy cows. Early weaning is a proven way to induce precocious puberty in heifers. Heifers will experience more estrous cycles before breeding, which is associated with increased …

Effects of early weaning on finishing feed efficiency, marbling development and retail product quality of beef steers
… its positive effects on maternal productivity, early weaning is one such alternative strategy that has received considerable interest. To better understand the effects of early weaning on calf productivity, an extensive literature review and three experiments were conducted to evaluate the …

Effects of prepartum supplement level and age of weaning on dam performance and developmental programming of male progeny
… effects of prepartum supplement level and age of weaning on cow BW, BCS, milk production, reproduction, calf performance up to weaning, growth performance, feed efficiency, glucose and insulin concentration, and carcass characteristics of male offspring. Mature, multiparous Angus × Simmental cows …

Influence of Prepubertal Dietary Protein and Age at First Calving on the Performance, Reproduction and Lactation of Replacement Beef Heifers
… prebreeding production settings including normal weaning and creep feeding, early weaning and creep feeding, and early weaning and confinement feeding. Replacement beef heifers utilized in the experiments were Angus, Simmental or a reciprocal crossbred of Angus and Simmental. Increasing …

Physiological responses of the small intestine to nutritional factors and rotavirus infection afflicting young pigs
… intestine in young pigs. Experiment 1: After early-weaning, pig performance is decreased mainly by a reduction in feed intake, which impacts swine production negatively. Feeding a milk replacer the first week after weining more than doubled weight gain compared to weaning to starter diet. …

An analysis of the breastfeeding practices of a group of mothers living in Victoria, Australia
… the causes of and variables associated with early weaning (during the first three months) by breastfeeding women. Prior to 1970, there was a decline in breastfeeding rates, with a gradual increase during the 1970's and 1980's. Since the late 1980's, even with increased knowledge, evidence …

Factors influencing cow performance and intake
… Two studies were conducted to determine how weaning system, residual feed intake (RFI), and residual average daily gain (RADG) affect cow performance and intake. In Study 1, a two-year study was conducted using Angus and Simmental X Angus heifers (n=114) to evaluate how weaning system (early …

Nutritional Management Affects Feedlot Performance, Carcass Characteristics and the Relationships of Intramuscular Fat, Subcutaneous Fat, and Feed Efficiency of Normal and Early -Weaned Heifers
… ultrasound technology. The data suggested that early weaning heifers and finishing them as calves resulted in more efficient gains (P ≤ 0.01) at any given marbling score and higher marbling scores at any given subcutaneous fat thickness (P ≤ 0.05) when compared to heifers grazed on pasture …

Breastfeeding experiences of call centre agents
… One of the main factors that contributes to the early weaning of breastfeeding infants in South Africa is the return to work. This study aimed to gain an in-depth understanding of the breastfeeding experiences of call centre agents when returning from maternity leave. This study employed a …

The influence of weaning age on growth and development of the baby pig and reproductive efficiency in the sow
… . A creep ration constituted the only diet from weaning to 56 days with the exception of pigs weaned at 1 or 7 days. These pigs were given a reconstituted “milk” in addition to creep feed from weaning to 14 days of age. An interaction between litter size and length of the nursing period on rat of …

Programmed Feed Intake of High Energy Diets Influences Digestibility and Maintenance Requirements of Beef Cattle
… serially harvested to determine the effects of early weaning and restricted intake on gastrointestinal tract and visceral organ mass. Programmed feeding of early-weaned steers was not effective for improving carcass or performance parameters (P > 0.05).

Effect of early grain feeding of steers on postabsorptive capacity to utilize acetate and glucose
… the first study were to determine the effects of early weaning followed by a period of high-grain feeding on signaling protein phosphorylation in muscle and on acetate clearance in growing steers. Twelve Angus X Simmental steers were used in the study. Six steers were weaned early (EW) and fed a …
