The Research On Application And Extension Of "Hualong" Fur-bearing Animal Special Feed

To ascertain the application condition of formulated feed in breeding fur-bearing animal. The thesis researched the application condition on breeding blue fox and mink of the growing period in practice, determined the digestibility of blue fox and mink in breeding the formulated feed and tested the effect of breeding to analyze the market demand condition of fur-bearing animal feed and the integral development prospect of fur animal feed industry.The digestion experiment of blue fox was in the growing period. The sixteen blue foxes were randomly divided into two groups according to sex and weight which were fed with the formulated feed group I (the formulated feed of breeding base) and the formulated feed group II ("Hualong"881 feed). The experiments were done to study the digestion in the growing period of blue fox by different feeds. Results showed that the dry matter picking had no difference between 2 groups (P>0.05). The dry matter and the crude protein digestion of the female blue fox had no difference between 2 groups (P>0.05). The dry matter, the crude protein and the energy of the male blue fox in group I were lower than group II (P<0.01). The digested dry matter and the digested crude protein of the female blue fox had no difference between 2 groups (P>0.05). The digested dry matter and the digested crude protein of the male blue fox in group II were higher than in group I (P<0.05). The picking, digestion, the digested of crude fat and the digestion energy in group II were higher than in group I (P<0.01).The breeding and digestion experiments of mink were in the growing period. The sixty-eight minks were randomly divided into two groups according to sex and weight which were fed with the fresh feed (comparison group) and the formulated feed (test group). The experiments were done to study the digestion and the effect of raising formulated feed in the growing period of mink. Results shows that the dry matter and the crude protein digestion of the female mink in group fed with fresh general feed were higher than with the formulated feed (P<0.05), and the male mink had significantly difference between 2 groups (P<0.01). The dry matter picking and the digested dry matter in group fed with the formulated feed were higher than with fresh general feed. The crude fat and the digestion energy digestion in test group were higher than in comparison group (P<0.01). The energy digestion had no difference between 2 groups (P>0.05). The average daily gains of the test group were higher than the comparison group.In the experiment of blue fox in the growing period, blue foxes adapt quickly to "Hualong"881 feed and the feeding effect is good. Lengthening the time of breeding the feed of group II ("Hualong"881 feed) would make the blue fox have better growth function than in group I . The breeding experiment of mink in the growing period showed that adopting formulated feed with some proportional fresh feed in raising mink would enhance the digested nutrient picking approaching or exceeding the group of breeding fresh feed. The method could gain the same even much better effect than the group of breeding fresh feed which was a rational method in improving growth performance and solving the puzzle of the feed sources. Using formulated feed was able to reduce infecting the disease possibility obviously of mink and blue fox. The formulated feed was facilitated in transportation, storage and use, required no refrigeration and was very convenient in processing. And it could lower production costs and enhance production efficiency.
