A comparative study on reproductive performance and productivity of the Black Bengal and Crossbred goat at Atrai, Bangladesh

Abstract

: The present investigation was carried out to detect the status of different productive and reproductive parameters of Black Bengal and Crossbred goats at Bandaikhara village under Atrai Upazilla of Naogaon district during the period of September to December/2005. The average age at first sign of heat of Black Bengal goats was better than that of Crossbred goats. In Black Bengal goat the average age at first kidding was 360.5±10 days, whereas, in crossbred goats it was 411.5±15.5 day. Significantly (P<0.01) lower the post partum heat period in Black Bengal goat than the crossbred goat. The average kidding interval in Black Bengal and Crossbred goats were 179±20 and 270±22 days respectively and differences are statistically significant (P<0.01). The usual numbers of kids at one time in Black Bengal goats vary from single to quadruplet. On the other hand, litter size of crossbred goat was single or twin. The average birth weight of Black Bengal goat was lower than Crossbred goats, which are statistically significant (P<0.05). The average body weight gain after 365 days is better in Crossbred than Black Bengal goats and statistically significant (P<0.01). The average milk yield in Crossbred goat was 1.05 liter/day, whereas, in Black Bengal goat, it produces milk that only nourished its kids. It was concluded that the reproductive performance like early maturity, larger litter size, shorter postpartum period, minimum kidding interval are better in Black Bengal goat. On the other hand productive performance like higher birth weight, maximum body weight gain, high milk yield, longer lactation length are suitable in crossbred goat.

Genetic variability in the body weight of Sudan desert goats

“…It was found that sire significantly (P<0.05) affected body weight at ages from birth to the 6th month. This result was supported by Mourad & Anous (1998) and Hassan et al (2007). Dam significantly affected kid body weights only from birth to the 2nd month of age.…”

Evaluation of the production characteristics of the Jamunapari goat and its adaptability to farm conditions in Bangladesh

“…Rout et al (1999) reported kidding interval was 229.3 ± 26.7 days, which is similar to the present findings. Due to long lactation, the kidding interval (210.6 ± 29.4 days) was longer than in Black Bengal goats (179 ± 20 days) as reported by Hassan et al (2007).…”

A Preliminary Study on Some Reproductive Traits and Heterosis Effects of Anglo Nubian and Etawah Grade Crossbred Does

“…The profitability of goat production depends primarily on the efficiency of female productivity. Improving female's reproductive performance by selection is difficult due to its low heritability (García-Peniche et al 2012) indicating that the possibility for genetic improvement through selection is limited, therefore, crossbreeding can be used to quickly improve reproductive performance via its resultant yield of heterocyst (Hassan et al 2007) and reproductive (Magaña & Correa 2001). However Nguluma et al (2013) reported that crossbreeding did not improve reproduction performance of local goats.…”
