The typical cattle production system in Ghana is predominantly pasture-based. Cattle are grazed all year round on natural pastures with minimal feed supplementation. The animals kept in this production system often experience inadequate nutrition and fluctuating nutrient supply affecting their productivity. There is presently limited information on the growth and reproductive performance of the Friesian x Sanga crossbred cattle (Plate 1) and factors influencing these performance traits. The growth and reproductive performance records of 150 Friesian x Sanga crossbred cattle, kept at the Animal Research Institute station in the Accra Plains of Ghana from April 1993 to October 2009 were evaluated to determine the effect of parity of cow, season of calving and sex of calf on birth weight, weaning weight, growth rate, age at first calving and calving interval. The birth weight and weaning weights of the calves averaged 21.8 ± 0.5 kg and 94.2 ± 3.8 kg, respectively, and were not (P > 0.05) affected by sex of calf, parity of cow or season of calving. Parity of cow affected (P < 0.05) weight of calf at 12 months. Calf weight at 12 and 18 months averaged 128.0 ± 3.4 kg and 159.9 ± 4.5 kg, respectively. Pre-weaning and post-weaning average daily gains were 0.33 ± 0.02 kg/day and 0.23 ± 0.03 kg/day, respectively, and were not significantly (P > 0.05) affected by sex of calf, parity of cow or season of calving. The mean age at first calving was 41.2 ± 1.2 months. Calving interval was prolonged averaging 441.6 ± 10.3 days and was significantly (P < 0.05) affected by parity of cow. Calving interval decreased with increasing parity of cow. The age at first calving and calving interval were not (P > 0.05) affected by either sex of calf or season of calving. The growth and reproductive performance of the Friesian x Sanga crossbred cattle was less than optimum. Improving their nutrition could impact, positively, on their productivity through fast growth, increased milk yield and early resumption of ovarian cycles after calving. Thus, results from this study should guide the development of appropriate strategies for increased meat and milk production in Friesian x Sanga crossbred cattle.

Sinh sản và sản xuất thịt là những tính trạng kinh tế quan trọng trong sản xuất chăn nuôi. Để cải thiện di truyền những tính trạng này, chỉ thị phân tử đã được ứng dụng rộng rãi ở nhiều nước có hệ thống chăn nuôi phát triển. Những nghiên cứu gần đây cho rằng gen RNF212 và NCAPG liên quan đến khả năng sinh sản và sức sản xuất thịt ở động vật có vú. Trong đó, đột biến thay thế nucleotide đơn C>T trên gen RNF212 được biết làm gia tăng tỷ lệ tái tổ hợp giảm phân ở bò. Hơn nữa, tỷ lệ tái tổ hợp giảm phân tương quan thuận với hiệu quả sinh sản nên đột biến này có thể là chỉ thị quan trọng liên quan đến khả năng sinh sản cao ở bò. Bên cạnh đó, đột biến thay thế nucleotide đơn A>G trên gen NCAPG được biết làm gia tăng khối lượng thịt xẻ ở bò. Do đó, trong nghiên cứu hiện tại, chúng tôi đã tiến hành phân tích đa hình gen RNF212 P259S và NCAPG I442M trên 2 tổ hợp bò lai bằng phương pháp PCR-RFLP. Kết quả phân tích chỉ ra rằng RNF212 P259S và NCAPG I442M là đa hình trong quần thể bò lai Sind và lai Brahman ở Việt Nam. Sự xuất hiện tần suất thấp của alen T (RNF212) và tần suất cao của alen G (NCAPG) có ý nghĩa quan trọng cho công tác chọn và lai tạo giống bò có khả năng sinh sản và năng suất thịt cao.  ABSTRACT Reproduction and meat production are considered as the most economically important traits in livestock production. In developed countries, the molecular markers have been commonly used in the animal breeding program  to find the favorable alleles in genes associated with economically important traits. The recent studies showed that RNF212 and NCAPG genes are involved in fertility and meat production in mammals, respectively. In which, T allele of RNF212 P259S gene was reported to significantly associate with a higher recombination rate in cow s. Of note, since the meiotic recombination rate correlates positively with the reproductive success of human females, the RNF212 P259S is expected to be a useful marker for increasing the reproductive performance in cattle. In addition, G allele of NCAPG I442M increased the carcass weight of cattle. Therefore, in this study, we conducted the polymorphisms of RNF212 P259S and NCAPG I442M by using PCR-RFLP in 2 crossbred cattle. The results showed that the RNF212 P259S and NCAPG I442M were polymorphic in Red Sindhi and Brahman crossbred cattle. The presence of T allele of RNF212 P259S and G allele of NCAPG I442M are informative for the future breeding of Vietnamese crossbred cattle.

Restricted suckling is one of the most common forms of livestock production in developing countries. It combines partial milk extraction and suckling, in a multi-commodity (milk and calf) production system.The objective of this experiment was to determine the possibility of the use of once daily suckling to increase total milk production without reducing reproductive performance or the ‘ quantity’ of milk extracted at milking in crossbred cattle.A total of 36 cows, locally known as ‘Lucerna’, were placed into two treatments. 18 cows were non-suckled and 18 cows were restricted suckled once daily for 15 minutes following milking (p.m.). All experimental cows had completed two or more lactations and at 3 days post partum were simultaneously allocated to the treatments according to: parity; condition score; previous lactation yield and calving interval. The cows remained in the experiment for 100 days.

This study was conducted to compare the productive and reproductive performance of indigenous and crossbred cow likely Friesian, Sahiwal and Sindhi cross. A total of 180 dairy cows were selected randomly from four upazilas of Comilla district. It was observed that mean milk yield and lactation length of indigenous, Friesian cross, Sahiwal cross and Sindhi cross were 2.35±0.04, 7.36±0.11, 4.78±0.08 and 4.03±0.05 litre/day and 218.22±8.35, 284.69±1.64, 251.77±3.66 and 259.77±4.91 days respectively. It reveals that the Friesian cross is the best performer in relation to milk production and lactation length. About the reproductive performances it shows that indigenous cows need minimum (1.81±0.048) services per conception. Gestation length was shorter in case of Sahiwal cross (277.64±1.99 days) and it varies within Friesian and Sindhi cross in a short range (278.77±1.38 to 279.31±1.00 days). Calving interval was lower in Friesian crosses (413.77±53.87 days) than its counterparts. Age at puberty was shorter in Friesian cross (662.44±2.52 days). It interprets that Friesian cross was the best performer than other crossbred and indigenous cows in dairy potentialities. DOI: http://dx.doi.org/10.3329/bjas.v37i1.9866 BJAS 2008; 37(1): 39-43

The study was conducted at Sylhet Govt. dairy farm to evaluate the productive and reproductive performance of Jersey× Frisian (J×F), Jersey × Local (J×L) and Sahiwal × Local (SL×L.) crossbred during the period of April 2007 to August 2009. Data on milk yield and different reproductive traits like lactation length, milk yield, length of dry period, service per conception, gestation length and post-partum heat period were evaluated. Results indicated that milk yield, length of dry period, service per conception and post-partum heat period were significantly affected (P<0.01) by different crossbred. However, lactation length and service per conception were significantly affected (P<0.01) by parity and interaction of breed × parity. The highest lactation length was observed for the genotype Jersey × Friesian (J×F) and the lowest was Jersey × Local (J×L) in the first and second lactation. The highest milk yield was observed for the genotype J×F and the lowest was J×L. The highest length of dry period was observed in SL× L and lowest was J×F. Furthermore maximum services were required for J×F. The highest gestation length was observed for genotype SL×L. The highest post-partum heat period was observed J×F. The overall reproductive performance of different crossbreds were varied.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16466 Progress. Agric. 22(1 & 2): 47 - 54, 2011
