Correlation Estimates between Carcass Traits of Nili Ravi and Kundhi Buffalo
Present study was designed to estimates the correlation between carcass traits of Nili Ravi and Kundhi buffalo. The data for carcass traits of Nili Ravi and Kundhi buffalo was collected from Seven Star International Meat Processing Company Dhabeji at Thatta. In current study the data of total 100 animals of Kundhi and Nili Ravi breed were selected and divided into A, B, C and D group. In group A and C there were Kundhi and Nili Ravi male whereas, B and D females of both breeds respectively. The data including live body weight, carcass weight, dressing percentage and boneless weight of both breeds Kundhi and Nili Ravi were collected for the estimation of correlation.The results for correlation estimates of different carcass traits indicated that the correlation estimation were found positive and high among Nili Rave breed as compared to Kundhi breed, which shows that an increase in one carcass trait would increase the other carcass traits. It was concluded that Nili Ravi carcass traits are better expressed and produces more beef than Kundhi, while Kundhi male is better in beef production than the Nili Ravi female whereas Kundhi female produces low carcass yield.</jats:p
Heritability Estimates for some Performances Traits of Baluchi Sheep
Present study was carried out to estimates the genetic parameters of Baluchi sheep during the year 2015 at Bhagnari cattle Cum Baluchi Sheep Farm Usta Muhammad, Baluchistan. The recorded data including (lactation yield and lactation length) was collected for the period 2005 to 2014.The results of current study revealed that average milk yield and lactation length was found 95.1±11.122kg and 123.60±8.44days of Baluchi sheep. The results for heritability and correlation estimates for lactation yield and lactation length was observed 0.113, 0.126 and 0.26, respectively. There was positive and low heritability and correlation was worked out for lactation yield and lactation length. Due to low results heritability and correlation estimates of some performance traits of Baluchi sheep, it was concluded that improvement can be achieved by process of mass selection.</jats:p
Analysis of Growth and Carcass Traits of Dumbi Sheep Breed Male Lambs Different Management Systems
Present research was performed on twelve male lambs of Dumbi sheep breed kept in 2 management systems at Faculty of Animal Husbandry and Veterinary Sciences, | department of Livestock Management, Sindh Agriculture University, Tandojam. Animals were divided into two different groups. A groups animal were kept in semi intensive with provision of open grazing and concentrates while, Bgroup animals were kept in intensive management system with provision of green fodder and concentrate. Study was performed till 8 weeks and lambs were observed weekly foraverage body weight and carcass characteristics of both groups were recorded. The results of current study showed that average body weight of group A was (8.33 kg)found significantly high (P>0.05) as compared to the group B (6.86 kg). Moreover carcass characteristics of Dumbi lamb was also observed higher in group A as compared group B. While during comparison of the economical values of both groups, it was observed that group A was found more economical than group B. It is concluded that semi-intensive management system was found better as compared to intensive management system.</jats:p
Effect of Genetic Parameters on Some Growth Performance Traits of Harnai Sheep
Present study was performed to estimates the genetic parameters forsome growth performance traits of Harnai sheep. The data was recorded for the period of 2004-2013 from the Multi-purpose research centre Yetabad, District, Baluchistan. The performance traits including birth, yearling, weaning and fleece weight was recorded for the estimation of genetic parameters. There was no significant difference was observed parity and Ram wise among some growth performance traits of Harnai sheep. While the results for heritability, estimation for birth weight, yearling weight, weaning weight and fleece weight was observed low to medium for some growth performance traits of Harnai sheep. It is concluded that low heritable and correlative traits mainly affected by the management, nutritional and temporary environmental conditions, hence improvement can be achieved through the better selection.</jats:p
Heritability Estimates for Some Growth Traits of Dhatti Camel Breed in Tharparkar
Purposed study was conducted using 12 sire”s 232 offspring. The parameters were studied birth weight, body weight, weight at 6 month, average daily gain to 6 month, yearling weight, total weight gain from 6 month and average daily gain from 6 month till one year. The results for heritability estimates were analyzed using the variance with unequal subclass numbers by using the data of 12 parental half sib groups. The average numbers of offspring were ranged per sire 3 to 84 with mean of 16.4. The effect of sire was observed significantly higher (P≤.0) in said traits. While the results of heritability estimates were observed low to moderate for birth weight, birth weight at 6 month, average daily gain to 6month, yearling weight, total weight, weight gain to 6 month and average daily gain from six month to 1 year respectively. The results for correlation estimates between these traits were positive and high for bwt with TG6 month and bwt at 6 month with and 6 month to 1 year. It is concluded that values for heritability and correlation were observed in range of other farm animal, while for the better production and higher values selection process is advisable for these traits.</jats:p
