  "abstract": "<p>Sahiwal cattle of Pakistan is one of the best zebu cattle breed that can potentially play the same role as Holstein for<br>tropical environment. The environmental factors are generally influenced the Sahiwals' performance as well as other<br>breeds. The performance traits reviewed were age at first calving, milk yield, lactation length, dry period, calving<br>interval, and service period of Sahiwal cows. The average age at first calving among Pakistani Sahiwals ranged from1242&plusmn;6.7 to 1358&plusmn;7.9 days. It was 1094 to 1263 days in Indian Sahiwals while Kenyan herd was reported to have<br>1293&plusmn;9.3 days of age at first calving. Lactation milk yield have been reported 1474&plusmn;15.4 kg to 2058.3&plusmn;9.25 kg in 247 to<br>318 days longer lactations in Pakistani Sahiwals. Reports on dry period have a range of 148 to 245 days while the<br>lactation milk production for Indian Sahiwals was almost in the same range 1455&plusmn;10 to 2177.8&plusmn;40.8 kg in 274&plusmn;0.8 to<br>372&plusmn;8 day long lactations. All the productive and reproductive traits were affected by herd, year, season of calving and<br>parity. The phenotypic correlations among various performance traits have also been reported. Phenotypic deterioration<br>in milk yield was noted over the years.&nbsp;</p>",
