An experiment was conducted in which adult Suffolk ewes were given an ad libitum diet for 9 months and then compared with control sheep fed a maintenance diet. The changes in body weight and food intake could be divided into three phases. In the first phase, a high food intake 3-3.5 times the maintenance level corresponded to a high body weight gain of more than 200 g/day. In the second phase, ...

This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

Meat quality and cut yield of pigs slaughtered between 100 and 150kg live weight were evaluated. Pigs (417 Agroceres PIC barrows and gilts) were fed a daily allowance of 2.8kg per head from 80kg until 100.71±0.85, 118.58±0.99, 134.07±1.18 or 143.90±1.24kg live weight. Seventy-one pigs were used for the evaluation of primal and subprimal cuts. There was no interaction between sex and slaughter w...

Toward the end of mitosis, neighboring chromosomes gather closely to form a compact cluster. This is important for reassembling the nuclear envelope around the entire chromosome mass but not individual chromosomes. By analyzing mice and cultured cells lacking the expression of chromokinesin Kid/kinesin-10, we show that Kid localizes to the boundaries of anaphase and telophase chromosomes and co...

the objective followed in the present study was to survey the relationship between 18 body trait measurements (live weight, height at wither, paunch girth, neck diameter, body length, girth around the body, width of fat tail at above, below and midpoint of fat tail, fat tail length lowers right and left sides, fat tail gap length, fat tail depth at the above, below, and midpoint, and girth arou...

twenty male raini goats with an average live weight of 30 ± 2.5 kg and 18 month of age. ,were used in a completely randomized design with 4 experimental diets and 5 replications to study effect of different levels by-pass(udp) protein(2.75, 4.86, 5.91 and 6.97 percent in dry matter) on growth and carcass characteristics. metabolismable energy (me) level of the all diets were similar (10.04 mj m...
