Jersey (J) cow was raised under a hot and humid environment but they were in the same feeding program for Taiwan dairy cows. Summer milk production is critical to evaluate the performance of those of new imported Jersey. For breeding scheme of dairy cattle, selection on milk yield and quality associated with reproductive performance is essential to the hot and humid weather, and therefore selected cows will become a heat-tolerance line for exportation to Southeast Asia. In the summer of 2007, 680 milk samples taken from Jersey cow with comparison to statistics of 218,818 milk samples of Taiwan dairy cows (T) in 2006. Jersey cow had 27 kg of single day production yield (63 kg in T cow) with a mean of 15.5+4.0 kg (22.7 kg of mean in T cow). Milk fat, protein, lactose, and total solid were 4.69+0.97, 3.48+0.40, 4.83+0.30, and 13.71+1.04%, as comparison of T cow in which of 3.81% fat, 3.30% protein, 4.79% lactose and 12.59% total solid. J cows had a significantly higher fat percentage. Somatic cell counts averaged 722x103/mL in J cow and significantly higher than the average of 322x103/mL of T cow. Milk urea nitrogen, citric acid, and P/F ratio in J milk were 14.4+5.8 mg/dL, 190.0+27.9 mg/dL, and 0.78. When milk yield was classified into <10, 10~21, and >21 kg groups, frequency of them were 47(6.9%), 589(86.6%), and 44(6.5%). An average of 23.2+1.3 kg of milk yield in the high yield group with 4.48+0.89% fat, 3.38+0.20% protein, 4.79+0.21% lactose and 13.36+0.94% total solid. It indicated that high yield resulted in a less fat percentage. In conclusion, selection on both milk yield and quality trait in Jersey would be feasible.

Chicken broodiness is considered as one of the major factors that decrease the potential of egg production. In order to set up a F2 design reference family for mapping of broodiness, the F1 hybrid progenies was produced by reciprocal crosses between LRI native chicken inbred line 9( LRI-L9) and Leghorn, and F2 progenies was produced by fullsib mating of F1. Prolactin receptor gene(PRLR) was on sex chromosome Z. Records of genotyping of DNA extracted from blood merged with broody records was used to explore the association between broodiness and genotype. PRLR of PCR-SSCP has three genotypes. The genotype frequency of PP, PR and RR in LRI-L9 were 42.4%, 42.4% and 15.2%, respectively. But, all leghorns were PP type in the collected samples. The G0 data showed an strong association between breed and genotype (P<0.001). Eighty percent of hens of F2 don’t express broody behavior. The average broody days of broody hens, with more than three days continually broody records, were 19.6 days. The link between PRLR genotypes and broodiness was also significant in the F2 data set (P<0.01).

Breeding scheme of dairy cattle, selection on milk yield and quality associated with reproductive performance is essential to the hot and humid weather, and therefore selected cows will become a heat-tolerance line for exportation to Southeast Asia. Data were used to rank the top 100 records on daily milk yield and their age and milk quality from January of 2001 to September of 2007 based upon www.angrin.tlri.gov.tw. The highest of 68 kg daily milk yield was recorded and the 100th record was 56 kg with a mean of milking age of 61.8+18.8 months old ranging between 32 and 121 months of age. There was 50% (50/100) of highest daily milk yield cows within 60 months of age. For those of Top 100 daily milk yield cows, milk fat, protein, lactose, and somatic cell counts were 3.37+0.91%, 2.90+0.29%, 4.72+0.24%, and 155+221x103/mL, as comparison of 218,818 milking samples in 2006 in which of 3.81% fat, 3.30% protein, 4.79% lactose and 322x103/mL. Top 100 cows had a significantly less fat%, protein%, and somatic cell counts. It indicated that high yield resulted in a less fat and protein percentage. Top record of each year from 2001 to 2007, there were 66, 62, 61, 63, 62, 63 and 68 kg, respectively, with the age of milking were 41, 90, 77, 70, 54, 46 and 60 months of age. Top record cows were raised in county of Kaohsiung, Yunlin, Yunlin, Pingtung, Yunlin, Changhua and Taoyuan. In conclusion, selection on both milk yield and quality trait in those of above 56 kg on daily milk yield cows along with traits of milk fat, protein, lactose and somatic cell counts would be feasible.
