The experiment was carried out in starting period and finishing period to investigate the effects of different kinds of metabolic energy,crude protein,calcium and phosphor in rations on the utilization rate of nutrients for Hepu gooses by means ofL9(34) orthogonal design respectively.

The results showed that the apparent metabolism rates of crude protein and amino acid were highest when the level of lysine,methionine and threonine for Hepu goose were 0.

Two-phase experiments were conducted to study the effect of dietary lysine,methionine and threonine on growth performances,blood biochemical parameters,apparent metabolism rates,slaughter performance and meat quality of Hepu goose.

Estimation on the Nutritive Value of Guimu N0.1 Forage ( Pennisetum americanum×P. purpureum ) on Hepu Grey Geese;

One hundred and eighty Xupu breeder geese(240 d of age)were randomly assigned to one of five treatments with three replicates in each one(12 animals/replicant).

Three hundred Xupu breeder geese(300 days of age)were randomly assigned to one of five treatments with three replicates in each one and injected with LHRH-A3 with different dose(0 μg,5 μg,10 μg,15 μg and 20 μg per bird,respectively).

Effect of Dietary Crude Fibre Level on Growth Performance of Fatty Liver Geese during 6-10 Weeks and Comparing Study on Dynamics of Lipid Storage in Fatty Liver of Landes Geese and Xupu Geese;

150 male China Xupu geese of about 1d age were selected as experimental animals.

Genome RNA was extracted from leg muscle of Xupu geese,MSTN gene mRNA was amplified by using RT-PCR,the PCR product was cloned into pGEM-T vector.

This study took PRL gene as a candidate which strongly relates to the broodiness, through designing seven pairs of primers to clone and sequence the PRL coding regions of Xupu white goose and Zi goose.
