(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...

OBJECTIVE To test whether there are differences in diet diversity between children still being partly breast-fed at 9 months and those completely weaned at the same age. DESIGN Cross-sectional study. SETTING Cross-sectional study (SKOT cohort) in the area of Copenhagen, Denmark. SUBJECTS Healthy term infants (n 312) at 9 months of age (mean 9·1 (SD 0·3) months). RESULTS The infants part...

Lifetime (5 yr) lamb production and wool production from 207 straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system were evaluated for ewe fertility, prolificacy, ewe fleece weight, and total lamb weight weaned per ewe exposed. Data included 2,620 ewe exposures, 2,384 parturitions, 4,638 lambs born, and 3,498 lambs weaned. E...

Segregation and medicated early weaning are technologies used to optimize the productivity and health of pigs, but these practices may also cause aberrant behaviors indicative of stress. Thus, differences in early- (=10 d of age) and late- (=30 d of age) weaned pigs were investigated. At weaning, pigs were housed in groups of four in 16 pens (eight pens per treatment) in the same facility, and,...

Using red kangaroos Macropus rufus Desmarest, a large (>20 kg) marsupial herbivore, we compared the digestive capabilities of juveniles with those of mature, non-lactating females on high-quality forage (chopped lucerne Medicago sativa hay) of 43+/-1% neutral-detergent fibre (NDF) and poorer quality, high-fibre forage (chopped oaten Avena sativa hay) of 64+/-1% NDF. On chopped lucerne apparent ...

Our previous work has demonstrated that weaning at 19 days of age has deleterious effects on mucosal barrier function in piglet intestine that are mediated through peripheral CRF receptor signaling pathways. The objectives of the present study were to assess the impact of piglet age on weaning-associated intestinal dysfunction and to determine the role that mast cells play in weaning-induced br...

In 45 primiparous sows, we examined endocrine, ovarian and reproductive responses to split-weaning or five injections per day of 800 ng GnRH from 18 to 21 days of lactation. There was no effect of treatment on absolute or changes in sow weight or backfat depth during lactation. Average piglet growth rates were similar among treatments except that piglets suckling split-weaned sows grew faster (...

TODOROV, N., M. SIMEONOV AND A. KIRILOV, 2013. Feeding early-weaned lambs with pelleted dry distillers’ grain with solubles (DDGS) plus whole grain, and two methods of supplying minerals and vitamins. Bulg. J. Agric. Sci., 19: 810-816 The aim of the experiment is to examine possibilities to feed early-weaned lambs with pelleted DDGS, whole maize grain and alfalfa hay when minerals and vitamins ...

this experiment was carried out to study the effects of sainfoin (onobrychis viciifolia) as tannin source and different level of forage: concentrate ratio on digestibility, blood parameters, ruminal fermentation, milk yield and milk composition in milking ewes. therefore, eight lori milking ewes were alocated to factorial experiment base on the 4×4 replicated latin square design. four total mix...
