Test-Day Milk, Fat and Protein Yields as Selection Criteria in Egyptian Buffalo

GENETIC ASSESSMENT AND TRENDS FOR MILK PRODUCTION TRAITS IN A HERD OF EGYPTIAN BUFFALOES (Bubalus bubalis)

“…As shown in Table 1, the mean ±Std (CV, %) of TMY was 1905.52 ±416.17 (21.84) kg. It is higher than the means of many investigations done in Egyptian buffaloes as follow;1429, 1649, 1546.5,and 1420 as recorded bymany authors (Mohamed et al, 2010, El-Naser, 2020, and El-Bramony et al, 2017. In addition, it is lower than that detected by others as follow; 2070 kg, and 10551 kg as documented by (El-Awady et al, 2016b andAbdel-Baray et al, 2017), respectively.…”

“…Moreover, negative rp between SCC and milk traits which ranged from -0.01 to-0.20 (El-Arian et al, 2012). Additionally, the rp between TMY and SCCwas0 -0.13;Also, SCC had very weak and negative rp with both MY (-0.02) andPY (-0.03) and almost no correlation with FY (0.01) (El-Bramony et al, 2017). However it was estimated 0.96 and 0.96 between MY and (FY and PY) were, respectively; and0.95 between FY and PY (El-Bramony et al, 2017).…”
