“…Mirhabibi et al . (), in a study of buffaloes from southern Iran, reported a decrease of 32 kg (1.76% of average) in individuals with F = 0.25. In other words, a 1% increase in inbreeding decreases the production by 1.28 kg.…”

“…Higher values for depression from 4.497 buffaloes (34.7% inbred animals) were reported by Santana Júnior et al (2011), who estimated an average decrease of 107 kg (5.66% of average) for animals with 25% inbreeding compared to non-inbred animals. Mirhabibi et al (2007), in a study of buffaloes from southern Iran, reported a decrease of 32 kg (1.76% of average) in individuals with F = 0.25.

The objective of this study was to evaluate the influence of inbreeding depression on traits of buffaloes from Brazil. Specifically, the traits studied were body weight at 205 and 365 days of age, average daily gain from birth to 205 days (ADG_205), average daily gain between 205 and 365 days (ADG205_365) in Mediterranean buffaloes, and milk yield, lactation length, age of first calving and calving intervals in Murrah buffaloes. Inbreeding effects on the traits were determined by fitting four regression models (linear, quadratic, exponential and Michaelis-Menten) about the errors generated by the animal model. The linear model was only significant (P < 0.05) for growth traits (exception of ADG205_365). The exponential and Michaelis-Menten models were significant (P < 0.01) for all the studied traits while the quadratic model was not significant (P > 0.05) for any of the traits. Weight at 205 and 365 days of age decreased 0.25 kg and 0.39 kg per 1% of increase in inbreeding, respectively. The inbred animals (F = 0.25) produced less milk than non-inbred individuals: 50.4 kg of milk. Moreover, calving interval increased 0.164 days per 1% of increase in inbreeding. Interestingly, inbreeding had a positive effect on age at first calving and lactation length, decreasing age of first calving and increasing lactation length.

“…The inbreeding depression was −8.95 kg in estimated breeding value (EBV) of milk production, −0.37 kg in EBV of fat and −0.36 kg in EBV of protein. An inbreeding depression has also been found in other breeds such as buff aloes in Southern Iran (Mirhabibi et at., 2007), and Egyptian buff aloes (Khattab et al, 2007).…”

The aim of this study was to explore the depression effects of level of inbreeding on kg of fat and protein presented in the form of breeding values. The data included cows calved in the years 1990–2006 at farms in the Czech Republic. Inbred cows were grouped according to Fxcoefficients (Fx= 1.25%, Fx= 2.0–3.125%, Fx= 4.0–12.5% and Fx= total). The breeding values for inbred cows were compared with their outbred equals (2689 equals in sum) – half–sisters, sharing the same sire, dam reaching the same breeding value (± 5%) and their first calving occurring at the same farm, at the same time (±2 month). The PROC GLM of SAS®with fixed effects (age at first calving, year of calving, number of lactations, first calving interval and relative breeding value of sire and dam were applied to all data).In the groups with Fxcoefficients (Fx= 1.25 %, Fx= 2.0–3.125 %, Fx= 4.0–12.5 % and Fx= total) we found a decrease in the breeding values of kg fat in inbred cows of −1.48; 0.17; −8.26 and −0.51 kg. In the case of protein content the depressed production in inbred cows was: −0.58; −0.48; −3.21 and −0.94 kg. These differences were significant (p ≤ 0.01) in the group with the highest Fxvalue (Fx= 4.0–12.5%). The inbred animals showed higher variability within the range of observed corrected breeding values (Yijklmno) for kg of fat and protein.The results also show that increasing the level of parents (as RBV) caused a very significant increase in production both in inbred and outbred daughters but greater increase in fat and protein was evident in the non–inbred cows.

“…This helps to understand whether they influence any quantitative trait, especially in a population of small population size, such as local breeds (Biscarini et al, 2015). The negative effect of inbreeding depression in milk production has been reported in Egyptian (Khattab and Kawthar, 2007), South Iranian (Mirhabibi et al, 2007), and Brazilian buffalo populations (Santana et al, 2011). We found several differences among German buffalo populations in ROH analysis in terms of the number of hotspot SNPs, candidate genes in the same genomic coordinates, and biological processes in which they could be involved.…”

Genetic Diversity of Bubalus bubalis in Germany and Global Relations of Its Genetic Background

This is the first study to explore the genetic diversity and population structure of domestic water buffalo (Bubalus bubalis) in Germany and their potential relations to herds in other parts of Europe or worldwide. To this end, animals from different herds in Germany, Bulgaria, Romania, and Hungary were genotyped and compared to genotypes from other populations with worldwide distribution and open to the public. The pilot study analyzed population structure, phylogenetic tree, and inbreeding events in our samples. In buffalos from Germany, a mixed genetic make-up with contributions from Bulgaria (Murrah breed), Romania, and Italy was found. All in all, a high degree of genetic diversity was identified in European buffalos, and a novel genotype was described in Hungarian buffalos by this study. We demonstrate that European buffalos stand out from other buffalo populations worldwide, supporting the idea that buffalos have not completely disappeared from the European continent during the late Pleistocene. The high genetic diversity in European buffalos seems to be an excellent prerequisite for the establishment of local breeds characterized by unique traits and features. This study may also be considered as an initial step on the way to genome characterization for the sustainable development of the buffalo economy in Germany and other parts of Europe in the future.
