Lambs were kept in individual divisions and given 150 g/day roughage (alfa alfa hay (AH), meadow hay (MH), wheat straw (WS), concentrated feed and water ad libitum. Treatment lasted 70 days in total; temperature and humidity were recorded daily. Fattening performance, carcass parameters and ruminal pH levels were not affected by the treatment (P>0.05). Additive increased the weight of the hearts which were fed with AH (P<0.05). Effects of roughage and additive interactions on the acetic, propionic and volatile fatty acids was found as significant (P<0.01). IYM, increased the rates of acetic acid/propionic acid feeding with AH and MH (P<0.05). Ammonia concentration and digestibility of crude cellulose and hemicellulose was affected by the type of roughage (P<0.05). Digestibility of acid detergent fibre (P<0.01) and cellulose (P<0.001) was increased with additives. There is no difference among the groups in terms of water consumption (P>0.05). It’s concluded that, temperature and humidity is an efficient environmental factor on the fattening performance and IYM have positive effects on some cell-wall components digestibility and rumen parameters.","PeriodicalId":171549,"journal":{"name":"Lalahan Hayvancılık Araştırma Enstitüsü Dergisi","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123763218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reach the increasing market demands, a thoroughly organized breeding program is required. While most breeders focus on the female part of reproduction management, male selection constitutes the overlooked half. However, this forgotten part should begin with male selection through an andrological evaluation examination (Breeding soundness exam (BSE)). After the male selection, semen collected from these bucks can be transported to other herds easily and genetic advance can be achieved in a shorter period with the help of assisted reproductive techniques. Using selected males’ semen with artificial insemination (AI) in goats can bring huge improvement at goat breeding with its rapid and reform triggering effects. However, there are still missing pieces in terms of andrological examination evaluation and assisted reproductive techniques in goats and future research is still required to complete this puzzle. This review will focus on the selection of bucks and the advances in most commonly used assisted reproduction techniques in the field level.","PeriodicalId":171549,"journal":{"name":"Lalahan Hayvancılık Araştırma Enstitüsü Dergisi","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133528979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The least minimum squares method was used for determining the effect of environmental factors, and a Tukey multiple comparison tests were used for comparison. LL, LMY, and CI mean and their standard deviations were 260.26±1.33 d, 1035.5±8.21 kg, and 426.35±2.91 d, respectively. Calving year, season, calving age, and lactation number’s effect on those parameters were investigated. The effect of calving year (P<0.001) and season (P<0.01) on LL; calving year (P<0.001) and calving age (P<0.05) on LMY; calving age and lactation number (P<0.001), calving age (P<0.01), season (P<0.05) on CI were found statistically significant. Meanwhile, a high 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. It was concluded that obtained data relevant to these environmental factors will contribute to increasing yield parameters at buffalo farms via using stud selections and breeding studies as well as related researches.","PeriodicalId":171549,"journal":{"name":"Lalahan Hayvancılık Araştırma Enstitüsü Dergisi","volume":"393 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115026815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
