This study investigated the effects of sheep genetics and feed intake on nitrogen isotopic fractionation (ΔN) and feed conversion efficiency (FCE; live weight gain/DMI), using a 2 × 2 factorial design, with 2 levels of genetic merit for growth (high vs. low) and 2 levels of feed intake (110 vs. 170% of ME for maintenance [MEm]). No effect of genetic merit was detected for live weight gain ( = 0...

The weighing records of 18 crossbred females with average live weight of 14.7 ± 3.14 kg were analyzed to study the relationship of the growth of crossbred hair sheep with some zoometric measures. The weight was established and took the measures thoracic perimeter, cannon perimeter, body length, neck length, hip amplitude, ischial amplitude, withers height and croup height. All parameters were s...

BACKGROUND Representative data on pregnancy weight-gain patterns from developing countries are scarce. The reasons include difficulties in obtaining population-based samples and in collecting data before and throughout pregnancy. OBJECTIVE The objective was to measure weight-gain patterns from prepregnancy until after delivery in a population-based sample of rural Indonesian women. DESIGN T...

forty eight 8-month-old male goats were divided into three groups. in each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. at the end of restriction period, the restricted goats were offered the same ration ...

Forty-eight Suffolk Mule entire male lambs (22.3 kg average live weight, two months old) were used to study the effects of addition of sodium bicarbonate and increasing quantities of molassed sugar beet pulp (MSBP) to diets based on barley grain (780 g kgÿ1 fresh weight and approximately iso-energetic and iso-nitrogenous). Measurements were made of dry matter (DM) intake, growth, some ruminal a...
