Twenty eight Ossimi new born male lambs, with an average live body weight 4.75 kg and 7 days age were randomly assigned to two feeding groups each of 14 animals to study the effect of pre-weaning diet on lamb's performance. Both the two groups suckled their dams until being weaned at 12 weeks of age (natural weaning). The first group depended completely on dams milk as a solely available feed (...

Two trials were conducted to determine the influence of preshipment zeranol implant and protein and urea levels of the feedlot receiving diet on the performance of yearling steers. In each trial, one-half of the steers were implanted with 36 mg of zeranol 30 d before shipment from El Reno, Oklahoma to Bushland, Texas. In trial 1, receiving diets were fed to 14 d and contained 10.6 (LP), 12.6 (M...

An experiment involving 289 farrowings during a 2-yr period was conducted to determine the effect of increasing dietary nutrient concentration, electrolyte balance, and season of the year on the lactational performance of sows. Experimental diets were corn-soybean meal-based. The basal diet was formulated to meet or exceed the NRC requirements and the high-nutrient diet was formulated to contai...

The intestinal microbiota is critically important for animal health and productivity. However, the influence of on growth efficiency remains elusive. This current study was aimed at identifying bacteria that are associated with rate broilers in a commercial production setting. Ross 708 extremely high, medium, low body weight (BW) were separately selected each sex from house approximately 18,000...

Placental growth is a strong predictor of fetal growth, but little is known about maternal predictors of placental growth in malnourished populations. Our objective was to investigate in a prospective study the associations of maternal weight and body composition [total body water (TBW) estimated by bioelectrical impedance and fat and fat-free mass derived from upper arm fat and muscle areas (U...

OBJECTIVE Regular nut consumption is associated with lower rates of heart attack. However, as nuts are fatty foods, they may in theory lead to weight gain, although preliminary evidence has suggested otherwise. We tested the hypothesis that a free daily supplement (averaging 76 kJ) of almonds for six months, with no dietary advice, would not change body weight. METHODS Eighty-one male and fem...

A prospective study was carried out to determine the relationship between weight gain in the second and third trimesters with the corresponding birth weights in Morogoro, Tanzania. A total of 270 pregnant women who gave birth to singleton deliveries and their consecutive newborns were randomly selected from among women who were attending one antenatal clinic. Average weight gains in second and ...

A total of 74 pigs representing three commercially available crossbred types, Landrace (50%), Pietrain (50%) and Meishan (25%), were given food ad libitum over a 25to 115-kg growth period and serially slaughtered for physical and chemical analysis in five groups at 32, 42, 63, 82 and 114 kg live weight (W). Results are presented in the order of pig type as above. Pig types grew at similar overa...
