Objective: To model the effects of birth weight on preweaning survival and weights at weaning and at 42 days post weaning. Materials and methods: Individual birth-weight and weaning-weight records of 2467 pigs weaned at 14 to 21 days old were partitioned into nine categories incrementally increasing or decreasing by 0.5 SD (0.16 and 0.68 kg, respectively) from the mean (1.57 and 5.80 kg, respectively). To study the effect of birth weight on weight at subsequent phases, fixed effects of birth-weight category and parity of dam were included in the model for weights at weaning and 42 days post we

The present study was designed to determine the interrelationships between sex, weaning age, and weaning weight on aspects of physiological and gastrointestinal development in pigs. Forty-eight Large White × Landrace pigs were used in a factorial arrangement with the respective factors being: age at weaning (14 or 28 days), weight at weaning (heavy or light), sex (boar or gilt), and time after weaning (1, 7, and 14 days). At weaning, 48 pigs were removed from the sow: 16 pigs were then fasted for 24 h before euthanasia for determination of organ weights, gut histology, and enzymology, and 32 p

Restricted maximum likelihood estimates of covariance components and the resulting genetic parameters were obtained for birth, weaning, yearling and final weights and postweaning gain of Australian Charolais cattle fitting an animal model including genetic or permanent environmental maternal effects. No 'carry-over' of maternal effects till weaning on postweaning weights was found. Direct heritability estimates were 34, 41 and 22% for yearling weight, final weight and postweaning gain respectively. Maternal genetic effects were not important for birth weight and were small for weaning weight.

Two approaches, namely the regression techniques and maximum likelihood (ML) procedure were taken to estimate the above trends.

The objective of these studies was to evaluate the effect of piglet nursing location on weaning weight, and its dependence on essential oil supplementation on sow and piglet performances. Piglets that nursed anterior teat pairs had heavier weaning weights and higher gain for the lactation period. Additionally, piglet birthweight did not impact their overall teat selection and nursing location. These results provide some insight into the biological aspects of sow milk production, and implied that milk yield may vary between teat pairs along the udder line.

Breastfeeding provides almost all of the nutrient requirements for the growing infant to the age of 6 months. Complementary foods rich in iron should be introduced by 6 months, but continued breastfeeding past this point is still beneficial to the infant. It is also beneficial for the mother, reducing postpartum weight retention and lowering the risk of breast and other gynaecological cancers. Breastfeeding women have increased energy requirements to meet the energy costs of milk production. Some specific nutrient requirements also increase during lactation.

Survivability of piglets during the neonatal period has been decreasing as genetic selection for highly prolific animals continues across the swine industry. Piglets considered medium weight at birth (1.0-1.3kg) provide the greatest opportunity to improve survival. Colostrum consumption by the neonate after birth aids in thermoregulation and improves survival to weaning as well as provides passive immunity to the piglet from the dam to aid in health pre- and post-weaning.

The average body weight of lambs at birth was 3.67 kg, with 30 days of age 10.60 kg, and weaning weight 30.77 kg. The effect of fixed factors was studied within the frame of SAS software package. A statistically highly significant (**=P<0.01) effect on studied traits: average lamb birth weight (BW0), average

A study has been carried out on a sample of 102 Iraqi local dell and their offspring for the period 2021-2022 to study the growth prediction of lambs through the production of milk and its main components, the results obtained from this study after adjusting for factors are as follows., there is a positive relationship between weight gain at weaning age and at 6 months and an increase in the percentage of protein in milk at a significant (P≤0.05)and (P≤0.01) respectively. The regression coefficient of weight gain for age at weaning and age at 6 months on maternal milk production was by 3.208 a

One of the methods of increasing the productivity of pigs is the use of stimulants of productivity and preservation, while the focus remains on their safety. In this regard, the search for biologically active feed additives instead of antibiotics is of scientific and practical interest today. With this in mind, the influence of liquid and dry forms of phytobiotics «Liptosa Expert» on the intensity of growth of crossbred young pigs ((Large white × Landrace) × «Maxter») was studied. The use of phytobiotics «Liptosa Expert» in the period of weaning, rearing and fattening can be an effective metho

An experiment was conducted to study the inheritance of improved growth phenotypes in pigs born to sows injected with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) prior to mating. Twelve sows were assigned into a randomized design with 3 groups and each group consisted of 4 sows as replications. The first group consisted of sows without PMSG and HCG injection prior to mating as a control group (NSO). The second group consisted of sows injected with PMSG and HCG prior to mating to improve endogenous secretion of pregnant hormones that improve prenatal growth of

Heat production (HP) or energy expenditure for activity (EEa) is of fundamental nutritional importance for livestock because it determines the proportion of ingested nutrients available for productive functions. Previous estimates of EEa are unreliable and vary widely with different indirect methodologies. This leads to erroneous nutritional strategies, especially when intake on pasture does not meet nutritional requirements and supplementation is necessary for acceptable production. Therefore, the objective of this project was to measure EEa in different classes of livestock (beef cattle and
