Herbage intake regulation and growth of rabbits raised on grasslands: back to basics and looking forward

The authors focus iron intake regulation in the body and the probable mechanisms related to iron absorption. They analyze the impact of iron absorption deficiency resulting in iron deficiency anemia, a public health issue of great impact in the world influencing child and maternal health risk increase. This paper aims at highlighting the problems affecting the uptake or inhibiting processes of iron absorption in an attempt to correlate information on conditioning factors and current findings. This study is a document based descriptive study comprising literature review. In food, iron has different forms, such as the heme and non-heme forms following different absorption pathways with different efficiency rates, depending on conditioning factors, such as diet profile, physiological aspects, iron chemical state, absorption regulation, transportation, storing, excretion and the presence of disease, They also discuss the current difficulties in dealing with iron nutritional deficiency in vulnerable groups, children and pregnant women, and focus data on iron consumption, adhesion to breast feeding and the frequency of prenatal care visits.

Winter Feeding

ABSTRACTTwo experiments were conducted with weaned, suckled calves to investigate the effect of feeding level during the post-weaning winter on their subsequent performance when continuously grazed on pasture maintained at two sward heights. Low, medium and high levels of winter feeding resulted in winter live-weight gains of 0·31, 0·58 and 0·79 (s.e. 0·027) kg/day (P < 0·001) during the 152-day winter in experiment 1 and 0·44, 0·69 and 0·84 (s.e. 0·029) kg/day (P < 0·001) for 189 days in experiment 2. During summer (93 days in experiment 1 and 87 days in experiment 2) there was a significant effect of winter food level on performance when live-weight gains were 1·10, 1·02, 0·87 and 1·35, 1·23 and 1·19 (s.e. 0·060) kg/day for the low, medium and high winter food levels on the short and tall swards respectively in experiment 1 (P < 0·01) and 0·86, 0·66, 0·51 and 1·26, 1·18 and 0·91 (s.e. 0090) kg/day in experiment 2 (P < 0·001). The cattle showing compensatory growth had higher herbage intakes and it is postulated that this occurred because of a negative association between body fat and herbage intake. Sward height had a large positive effect on herbage intake and live-weight gain and it is concluded that for maximum intake on ryegrass swards, herbage height should be at least 8 cm. Lower levels of winter live-weight gain delayed the time to slaughter, but allowed cattle to achieve heavier carcass weights at a fixed level of fatness.It is concluded that there is no single optimum winter food level for weaned, suckled calves but that the choice will depend upon several factors, including availability of winter and summer food resources, the length of the winter feeding period, the desired date of slaughter and type of carcass to be produced.
