The study was conducted to evaluate the growth performance of crossbred dairy calves (Holstein-Friesian crossbred, HFX and Sahiwal crossbred, ShX) feeding a readily fermentable calf starter diet. The duration of the study was 17 weeks of which the first week was for the adjustment period. Ten healthy crossbred heifer calves of average 40 days old were selected for this purpose and they were divided into two groups according to their genetic materials (5 HFX and 5 ShX) in a completely randomized design. The calves were fed initially 0.25kg/day/calf of starter feed which was gradually increased up to 1 kg/day/calf. In addition to calf starter, a predetermined amount of whole milk (2 kg/day/calf) and ad libitum amount of green grass were also supplied to the calves. During the experimental period, growth parameters viz. body weight gain, body length gain, wither height gain, and hip height gain was measured weekly. After the whole study period, no significant difference (P>0.05) was found in case of the average weekly body weight gain and all the body measurements. The results suggest that calves fed a balanced calf starter can grow identically overcoming any breed variations. However, to provide a clearer idea about the effect of calf starter on different crossbred dairy calves broad-scale research should be conducted on an advanced level including more crossbreds or pure breeds.\u0000Asian Australas.

The study involved a sample size of 226 goats and provided insightful information on the distinctive capabilities of each type of goat breeds. Most of the doe were 21–30 months of age, and their weight was 21–30 kg. The feed supply for the doe was concentrated green grass, whereas the kids got supplementary feed like rice bran. Among the reproductive traits, age at puberty, age of first kidding, and age of the first conception were significantly (P<0.001) higher in Jamunapari goats, whereas aerial kidding intervals were found in 263.77 ± 54.26 days in crossbreeds. Postpartum heat periods were highest at 68.50 ± 5.53 days in Jamunapari goats at 1st and 2nd parity, though at 3rd parity, 22.96 ± 26.66 days were uppermost in Black Bengal. There was no significant effect of parity on lactation length or milk production. Though Jamunapari goats show the highest lactation length at 1st and 2nd parity, at 3rd parity, 2.56 ± 2.89 kg was the largest in Black Bengals. The mortality of kids was high in the second parity in Black Bengal and crossbreeds, whereas in Jamunapari, it was higher in the first and second parities. The mortality rate of kids under 20 days was high, which gradually decreased with the advancement of age. Different periparturient and postpartum diseases, like abortion, dystocia, retained placenta, etc., decreased the reproductive performance of goats. The Black Bengal goat exhibited superior productive and reproductive performance to Jamunapari and crossbred goats. The study's findings suggest that, in the southwestern region of Bangladesh, prioritizing Black Bengal goats for breeding programs could potentially enhance both productive and reproductive traits compared to Jamunapari and crossbred goats.\u0000Asian Australas.

Considering this, the current research was conducted to assess the computer and mobile software based animal recording system, which have important effect on production and reproduction on Red Chittagong cattle and their graded cattle. For this reason, this survey was conducted at well-developed pre-tested questionnaire through mobile application software under thirteen study areas. The study areas were selected based on the density of Red Chittagong Cattle population in those areas. After data collectionollected data were analyzed using SPSS 22.0 software and mean comparisons were estimated by LSD and Duncan method. Numbering (highest-11.32% at Godagari, lowest at Naikhongchari-4.25%), Artificial Insemination (highest 20% at Godagari and lowest at Naikhongchari-1%), service per conception rate (highest at Sylhet-1.37 and lowest at Swandip-1.14), calving rate (highest 12.34% at Anowara and lowest 4.20% at Keshobpur) and birth weight (highest 16.50±0.57 kg at Hathazari and lowest 12.79±0.49 kg at Godagari) were different in each regions. Lactation length, milk yield, and growth rate of two category cattle were found statistically significant (P<0.05) between two groups of cattle. These three productive parameters were higher for Red Chittagong Cattle (230±5.16 days, 3.10±0.13 L/day, 0.197 kg/day) respectively. The software based recording system helps to get proper data which will help for selection of superior sires and dams with high genetic merit as well as data can be restored anytime from this software based recording system.\u0000Asian Australas.
