“…The productive characteristics of Friesian cattle in Egypt, as well as native cows and their crosses, have been extensively studied, and genetic parameters for productive traits of imported cattle and their crosses with native cows have been estimated (Mostageer et al 1990). Improving production e ciency can be achieved through better environmental conditions, improving the mean breeding values of the population's members, or a combination of both (Katkasame et al 1996)…”

A total of 3023, 596, and 1189 lactation records for Friesian, Native, and their Crosses cows from 1994 to 2015 were utilized in this study to estimate and assess genetic and phenotypic parameters and breeding values for 305-day milk yield (305-DMY), lactation period (LP), calving interval (CI), and days open (DO) in these three genotype groups within the Egyptian context. Data were analyzed using the LSMLMW and MTDFREML programs. The analytical model included fixed effects such as season and year of calving, parity, and genotype groups, while random effects included animal and error. Unadjusted means for 305-DMY, LP, CI, and DO were as follows: 3597 kg, 362 days, 524 days, and 198 days for Friesian cows; 1399 kg, 199 days, 499 days, and 169 days for Native cows; and 2671 kg, 395 days, 556 days, and 215 days for Crosses cows. Genotype groups had a highly significant impact on all the studied traits. Heritability estimates were higher in both Crosses (0.32, 0.26, 0.25, 0.23) and Native cows (0.26, 0.28, 0.28) for productive and reproductive traits, respectively, compared to the Friesian cows (0.24, 0.22, 0.16, 0.17) for the same traits. Genetic correlations among productive and reproductive traits ranged from 0.10 to 0.86 for the three genotype groups, while corresponding phenotypic correlations were small to moderate and positive. The accuracy estimated for breeding values indicated that genetic improvement can be achieved through both sires and cows.

“…The exotic bull breeds are used for crossbreeding purposes to take advantage of potential heterotic effects (Mostageer et al 1990, Olson 2011. High productive imported animals like Brown Swiss or Holstein Friesian can be crossed with native cattle because such practice may allow the Egyptian native cattle producer to take advantage of appropriate combinations of the superior traits of Brown Swiss or Holstein Friesian breeds to yields heterosis which often referred to as hybrid vigor (Marai and Habeeb 2010a).…”

The objective of this study is studying the effect of genetic crossing on body water and body solids in growing calves under winter or summer season in Egypt. Twenty calves including 10 native calves and 10 F1 calves (♀ Egyptian cow × ♂ Holstein) were used through two experiments. The first experiment was conducted during winter season on ten calves including 5 native and 5 F1 calves with average 5-6 months of age. The second experiment was conducted during summer season on another ten calves with the same age and body weight including 5 native calves and 5 F1 calves. Results showed that summer season induced significant decreases in live body weight (LBW) by 27.2 kg in native and by 32.9 kg in F1 through 3 months and F1 calves were better than native calves by 23.2 kg and 17.5 kg under winter and summer seasons, respectively. Total body water (TBW) as percentage of LBW values increased significantly and total body solids (TBS) as absolute values through three months decreased significantly by 6.9 kg in native calves and by 9.0 kg in F1 calves due to exposure calves to summer season. Daily gain (BG) and daily solids gain (SG) decreased significantly due to exposure calves to summer season and F1 calves were better than native calves in live BG as well as in SG. The best values in gain were in F1 calves under winter condition and the worsted values were in native calves under summer season.

“…The Egyptian native cattle (Baladi) are characterized by low milk production inputs used in suckling their borne calves (Mostageer et al, 1990) and also low daily body weight gain (300-500g/d) according to birthing season (Habeeb et al, 2014). Therefore, due to low yielding, most of the milk producers are interested in importing dairy cattle from Europe or USA either for expansion existing or for new dairy farms.…”

The objective of this research is study the importance of crossing in improving body weight gain of native cattle calves during hot summer season of Egypt. Twenty healthy calves including 10 native cattle calves and 10 F1 (produced from mating Brown Swiss♂ with Native cattle ♀) were used in the experiment. The experimental calves of two groups were the same each of age and live body weight. Experimental calves of the two groups were exposed to mild climate of winter season for 3 months followed by exposure the same calves to hot climate of summer season for 3 months. Results showed that calves body weight gains (either live or solids) improved significantly in F1 (½ Brown Swiss x ½ Native) calves due to crossing process under both winter and summer seasons. Thyroid hormones (T3 and T4) values in both two groups were found to be highly significantly lower in summer than in winter. While cortisol level in calves of the two groups was significantly higher during summer than those in winter. Dry matter intake (DMI) in two experimental groups was significantly lower during summer than those during winter. Feed conversion (FC %) was significantly higher during summer than those during winter. DMI and FC% values were improved significantly in F1 calves due to crossing process under each of winter and summer season.It can be concluded that growth and feed performance in crossing calves are better than native cattle calves under each of winter and summer season.
