A total of 21 heads of buffalo in the early lactation period; milk yield averages, lactation periods, lactation numbers, live weights, and ages were selected and divided into three experimental groups, each consisting of 7 buffaloes. The experiment was conducted according to the crossover trial pattern. There was no statistically significant difference between the groups in terms of dry matter consumption and feed conversion ratio (p > 0.05). There were no significant differences between the groups in terms of milk yield and corrected milk yield (p > 0.05). In addition, there were no statistically significant differences between the groups in terms of milk fat, solid not fat, protein, lactose, and milk energy yields (p > 0.05). The better values of feed conversion ratio, higher milk yield, milk fat, milk protein and lactose were obtained in the group of ABF compared to the control and PBF groups. The milk pH, temperature, density, freezing point, ash, organic matter ratio and milk urea nitrogen values obtained at the end of the experiment were insignificant between the groups (p > 0.05). In conclusion, to increase milk yield and components of buffalo rations, it has been determined that ABF and PBF can be added to 250 g per animal per day and will not cause any side effects. When the groups to which bypass fat sources were added were compared, it was concluded that ABF had more positive effects on performance and milk composition than PBF.

In these ecosystems, trees exceeding a hundred meters in height and bacteria from microorganisms smaller than a micrometer live together; there are many aquatic and terrestrial systems where all forms of symbiosis, parasitism, and hyper-parasitism are observed. The weakness of these systems, which form the basis of the bio-economy by producing 60% or more of the world economy, can cause individuals, communities, countries, and the world economy as well as social life to suffer and huge losses. It has been witnessed many times throughout history that biological systems are attacked and some biological creatures or products are used as weapons. Nowadays, it is possible that living things with particular characteristics or some of their products can be used directly to attack humans or primary production or food production systems. The characteristics, usage, consequences of such agents, and what to do to be protected from them are extremely important for the relevant government authorities. Currently, it is explicitly observed that conventional warfare tactics are developing and diversifying, and terrorist attacks are gaining more importance day by day in this regard. Given the place and importance of agriculture, forest, food, and natural resources in our social life and economy, it is obvious that "agroterrorism" is a strategic issue that needs to be addressed and there are many measures to be taken in this context.

The least square means and standard errors for MYLL, TLMY, LL, and MYCI were 4.07  0.02 kg, 1078.6  7.54 kg, 263.83  1.16 days, and 2.75  0.03 kg, respectively. As a result of the study, the effects of village, calving year and age (P<0.001) and calving season (P<0.05) on MYLL; village, calving year and age (P<0.001) on TLMY; village, calving year and age (P<0.001) and calving season (P<0.05) on MYCI; calving age, village (P<0.001) and calving year (P<0.05) on LL were found statistically significant. Moreover, high positive phenotypic correlations between TLMY and MYLL (r = 0.78, P<0.001) and LL and TLMY (r = 0.67, P<0.001) were estimated. The results revealed that milk production traits might be improved by considering calving season and age in breeding studies and stud-selection programs in Anatolian buffaloes. Besides, it will remarkably contribute to the number of limited studies that have focused on this breed.

In this study, 1511 milk yield data belonging to 762 Anatolian buffaloes and 957 CI data belonging to 543 Anatolian buffaloes which has been reared in different environmental conditions between 2015-2019 under the scope of the Anatolian Buffalo Breeding Project being conducted in Bartın province. The least squares method was used for determining the effect of environmental factors, and Tukey multiple comparison tests were used for multiple comparison. Mean and standard deviations relevant to the LL, LMY, and CI were detected as 260.26 ± 1.33 days, 1035.5 ± 8.21 kg, and 426.35 ± 2.91 days, respectively. County, calving year, and season, age, and lactation number's effects on those parameters were investigated. The effect of calving year (P<0.001) county and season (P<0.01) on LL; county, calving year (P<0.001) and calving age (P<0.05) on LMY; lactation number (P<0.001) and calving age (P<0.01) and season (P<0.05) on CI were found statistically significant. Meanwhile, a highly significant positive phenotypic correlation was calculated between LMY and LL (r = 0.66, P <0.001). There are no adequate studies related to the environmental factors influencing lactation length, lactation milk yield, calving intervals of Anatolian buffaloes. Significant environmental factors detected in this study should be considered in selection programs.

In the study, the data of 2821 head buffalo calves born from buffaloes bred from the Anatolian Buffalo Breeding Project in Bartın province between 2015-2021 were used. In the present study, the effects of nongenetic factors such as district, calving year and season, calving age, and sex on BW 0 and growth performance characteristics were investigated. The mean and standard errors of the BW 0 , BW 6 , BW 12, ADG 0-6 , ADG 0-12, and ADG 6-12 values of buffalo calves were calculated as 28.33 ± 0.090 kg, 119.13 ± 0.459 kg, 173.53 ± 0.743 kg, 504.64 ± 2.31 g, 398.24 ± 1.88 g, and 304.27 ± 2.45 g respectively. In the study, except for the effect of calving age on ADG 0-6 and ADG 6-12 (p > 0.05), the effect of all other nongenetic factors on growth performance was found to be statistically significant (p ≤ 0.05). There is not enough research on environmental factors affecting growth performance at different ages in Anatolian buffaloes. The data on growth performances and significant nongenetic factors obtained in this study will be useful in the selection program and improvement in buffalo husbandry and enlighten future studies.

It is a dual-purpose goat breed, which is mainly raised for meat and milk, and it is the most numerous goat breed in our country [2] 2. The main indigenous goat breeds raised in Turkey are Angora, Honamlı, Kilis, and Hair goats, which constitute the majority (97%) of the goat population 3. In addition, low-yielding sheep and goats in our country are raised under wide conditions by breeders because they adapt well to harsh conditions [3]. It contributes to the Hair goat breeder and the economy with meat, milk, and hair yield, albeit a little [4]. Growth and survival rates of kids are important determinants of productivity in goat breeding [5]. Birth weight (BW) is an important factor for the growth and development of goats, reaching a certain weight at a certain age and for postnatal kid losses [6, 7]. In some studies conducted in our country, it was found that the Abstract: This study was carried out to determine the growth characteristics and survival rate until weaning, some reproductive characteristics of Hair goat, and the factors affecting these characteristics under farmer conditions in Kahramanmaraş province. In the study, a total of 19386 birth weight (BW) records of kids in 49 different flocks in 14 villages for 5 years (2014-2018), and a total of 18017 weaning weight (WW) records were used from the National Genetic Improvement Project of Sheep and Goat in Turkey (NGIPSG). The average BW, WW, and daily live weight gain (DWG) of the kids were determined as 3.17 ± 0.013, 15.81 ± 0.045 kg and 139.78 ± 0.502 g, respectively. Among the environmental factors examined on these characteristics, the effect of dam's age, year and season of birth, type of birth, and sex were found to be statistically significant (p < 0.01). While the average survival rate of the kids at weaning was 92.94% and ranged between 90.99% and 95.14% depending on the years the effects of dam's age (p < 0.01), year of birth (p < 0.01), season of birth (p < 0.05), sex (p < 0.01) and type of birth (p < 0.01) on survival rate were found to be significant. In the study, litter size and twin birth rate were found to be 1.10 and 9.9%, respectively. These results showed that the Hair goat was adapted to the region, and its breeding was carried out in a sustainable manner in the region.
