La rentabilité de l’élevage ovin est largement tributaire du nombre d’agneaux sevrés par brebis et par an (l’objectif devrait être d’au moins deux). Les races hautement prolifiques (par exemple, Finn, Romanov) utilisées dans le programme d’élevage peuvent atteindre et dépasser ces nombres. La survie de l’agneau résulte dans une bonne…

Principles and Experience Producers have traditionally raised calves in individual pens or hutches. This rearing system has had advantages of individual feeding, observation and reduced risk of cross-contamination. It is however, still labour intensive. Dairy cattle are naturally group-living animals. Group-housed calves can enjoy an early social interaction and learn…

Understanding the basic concepts of growth helps improve calf and heifer management. Early postnatal growth is the most efficient time to develop skeletal growth, muscle growth, deposit protein and attain the highest feed efficiency. Mammary development can be enhanced by liquid (milk) feed intake prior to weaning (Brown et al,…

Heifers are the future profit earners of a milking herd. The largest cost inputs are feed and the number of day’s growth to achieve first calving. Raising healthy, strong calves must be a priority in maintaining herd profitability. In the last few years, larger calf raising units and more attention…

Why Higher Protein? Capitalize on the rapid early growth potential of young calves. Meet the needs of the rapidly growing bone and muscle for protein. This encourages greater lean tissue deposition without excess fattening. Why Specific Protein : Fat Ratio? Provide the correct protein to fat ratio at these higher…

Ontario and Quebec dairy herds produce approximately 400,000 male calves annually. These calves are destined for several hundred veal producers.The goal of grain fed veal producers is to achieve the desired finish at the desired weight and age. The market-ready calf is typically 250-295kg at an age of 25-30 weeks.…

Numerous studies, back as far as 1968, have examined the effects of feeding increased rates of milk or milk replacer to young calves. Recent developments in this area of heifer rearing have led to enhanced feeding programs. Conventional calf feeding offers milk replacer, of 18-22% protein and 15-22% fat, at…

Product Profile A specifically formulated high protein milk replacer for excellence in raising heifer calves. The Need Intensive feeding programs have been a major topic for discussion and presentation over the last year. Their aim has been to maximize genetic growth potential, get heifers to breeding weight sooner and also…

The aim of beef production is to produce a high quality product with maximum efficiency. Factors that affect the carcass composition and carcass yield are: Weight and age Genotype Gender Growth rate and nutrition Conformation A typical growth curve involves a self-accelerating phase of weight increase from birth to puberty…

It is important to remember that the foundations of udder development are completed within the first 15 months of life. Mammary growth and development is a component of the reproductive process and is affected by hormonal changes that occur as the animal develops. The basic structures of the mammary gland…
