“…The performance of imported breeds is lower in hot environments than in their native environments (Madani and Mouffok, 2008;Nigm et al, 2015). It is well established in the literature that when dairy cattle are under heat stress, there is an increase in water intake and a decrease in dry matter, protein, and fat content of milk, as well as milk yield (Gorniak et al, 2014).…”

Algerian indigenous cattle breeds are well adapted to the harsh local arid and semi-arid environments. This study aims to summarize livestock practices, milk quality, and discuss the potential of local cattle breeds to maintain production capacity in the face of global warming conditions. A total of 175 smallholder farmers who practice the breeding of the Algerian local cattle breed were interviewed using a formal questionnaire. Following that, 122 milk samples were collected for physicochemical and bacteriological analyses. Climate data variability in the study area was evaluated. Results reveal that between 1980 and 2018, the average annual temperature rose by 0.3 ± 0.001 °C per year. Predictions suggest that by 2081 to 2100, temperatures could increase by 1.18°C under SSP1-2.6, 2.33°C under SSP2-4.5, and 4.59°C under SSP5-8.5. In the same period from 1980 to 2018, annual precipitation decreased by -0.99 ± 0.24 mm per year. Projections indicate a further decline of 22.5 mm for SSP1-2.6, 44.4 mm for SSP2-4.5, and 95.2 mm for SSP5-8.5 from 1980-2000 to 2081-2100. These changes in temperature and precipitation coincided with an expansion of cropland, which increased by 90.3% from 1992 to 2005. Conversely, pasture areas decreased by 53.7% between 1993 and 2009. A socio-demographic survey revealed that breeders have a low educational level (39.4% are unlettered). They own a small herd (6.84 ± 8.66 cattle). Moreover, the average daily milk production was 4.13 ± 2.12 Liters/cow, with acceptable physicochemical quality but poor bacteriological quality. Considering the climate change vulnerability of the study area, we can conclude that the exploitation of local breeds seems to be the best adaptation strategy to climate change effects. Conservation programs for local breeds can enhance biodiversity and ecosystem balance. Concurrently, genetic improvement programs have the potential to boost productivity and profitability, making substantial contributions to social equity and local economies.

This study armed to estimate of non-genetic and genetic parameters that affecting Study traits including lactation length (LL), total milk yield (TMY), and 305 day milk yield (305d-MY). The number of records used were 1630 lactation records over a period of 10 years of pure Friesian cows raised at the commercial station in northern Egypt. Analysis was performed using SAS (To estimate non-genetic factors ) In addition to the animal model (estimate genetic parameters). The most important results of the study that have been reached are summarized as follows: All non-genetic factors were significant for all the study traits. The overall mean for (LL), (TMY) and (305d-MY) was 358.3 days; 8675.3 and 7387.7 kg, respectively. Heritability values for were 0.13 ± 0.027, 0.28 ± 0.031, and 0.35 ± 0.030 for trait) f (LL), (TMY), and 305d-MY) respectively. Present results recommended the productive performance of Friesian cows can be improved through the adoption of appropriate management, nutrition, and breeding programs achieved through the selection program.
