Genetic polymorphims in the growth hormone (GH) gene were studied in 410 Holstein dairy cows. Genotyping was carried out using PCR-RFLP. Data were analyzed by the MIXED procedure to reveal the effect of GH genotypes on reproductive traits. GH-AluI had a favorable effect on exanimate traits except for the age at the first calving. The homozygous LL genotype seemed to be advantageous for calving interval and days open. A significant effect of different GH-AluI–MspI combined genotypes was found.

This study aims to investigate the screening of leptin genetic polymorphism and its effect on lameness prevalence. Prevalence of lameness was evaluated and results showed that genotypes and other factors included in the logistic regression model significantly affect the prevalence of lameness in Holstein cows (P < 0.01). The probability of lameness incidence varied between 37 % and 99 % with parity. This recorded incidence is greater in winter and autumn than in the summer and spring.

In this study, we first studied the expression of ZNF33B in bovine ovaries and early embryos, and we determined the expression position and quantity of ZNF33B in ovaries and the temporal and spatial specificity of ZNF33B expression in early embryos. Secondly, the G-61G>T mutation of 5' UTR in ZNF33B gene was studied. The frequency of the G genotype was 0.3489 and that of the T genotype was 0.6511. This mutation was significantly correlated with the superovulation traits in cattle.

To speed up the progress of marker-assisted selection (MAS) in cattle breeding, kinesin family member 1A (KIF1A) genes were chosen based on our previous genome-wide association study (GWAS) analysis results. We detected insertion/deletion (InDel) variation in these three candidate genes in 438 individual cattle (Xinjiang Brown cattle and Wagyu × Luxi crossbreed cattle). These findings may aid future analyses of InDel genotypes in cattle breeds and speed up the progress of MAS in cattle breeding.

The aim of this study was to evaluate the influence of body weight on the efficiency of dairy cows. Data were derived from 161 commercial Austrian dairy farms. An optimum body weight range for efficiency does exist as the relationship of milk yield and body weight is nonlinear. Specialized dairy breeds seem to respond more intensively to body weight range than dual-purpose breeds. Cows with medium weights are the most efficient. A further increase in dairy cows’ body weights should be avoided.

Improved milk yield in dairy cows results in worsening health and reproduction. Some linear traits are genetically associated with health and reproduction and can be used to assist selection programs. The National Breeding Centre for Dairy and Forage of Indonesia has not included linear traits in the breeding program. This study estimates genetic parameters of linear traits. The traits under study were found to be heritable and can be included in the breeding program along with milk yield.

The objective of this study was to predict dairy cows' body weight from body size measurements. Body weight is an important trait for both management and breeding. Data were derived from 167 commercial Austrian dairy farms. To ensure high prediction accuracy, the use of a combination of both heart girth and belly girth is recommended if the use of scales is impossible. The large and heterogeneous data set supported a valid prediction.

The impact of the milking technique on the individual animal and the reaction of the animal on the technique were investigated. With the use of objectively recorded data from automatic milking systems (AMSs), auxiliary traits that reflect animal behavior in the milking system were defined, free from subjective impressions of classifiers. There is an apparent possibility to breed cows for AMS systems based on AMS data, though it is imperative to have further validation based on larger datasets.

Dairy cattle breeders have exploited technological advances in regard to reproduction and genomics. The implementation of such technologies in routine breeding programs has permitted genetic gains in traditional milk production traits as well as, more recently, in low heritability traits like health and fertility. Here we review a number of technologies that have helped shape dairy breeding programs in the past and present, along with those potentially forthcoming.

The present study was based on the association of polymorphisms at LEP, CAST, CAPN1, GHR, FABP4 and DGAT1 genes with fattening performance and carcass traits in Simmental bulls. Results indicated that final weight, fattening period, total weight gain and average daily gain differentiated the CAST and CAPN1 marker genotypes. Moreover, a novel effect of the LEP A80V on carcass weight and dressing percentage was observed. The results could be indicative for future studies on beef production.

This study aimed to use survival analysis and examine the factors affecting functional herd life (FHL) of cows in Isfahan using the Weibull proportional risk model in Isfahan to estimate of breeding values for functional herd life. The SC, milk production, age at first calving and milk period showed significant effects on LPL (P < 0.001) according to the likelihood ratio test. Although there were some fluctuations in genetic trends, an overall increase was observed which leads to a longer FHL

The advantages of increasing lactation persistency in dairy cattle are indisputable on the practical herd level. More persistent lactation brings a longer high-production period. In this study estimate the breeding values of lactation persistency, test day of milk yield, somatic cell score, reproductive traits (calving interval, days open), and longevity in Slovak Holstein dairy cattle were estimated and the relationship between persistency of lactation and other selected trait was analyzed.

AGPAT6 is a key candidate gene in the lipid metabolism pathway. We detected two single nucleotide polymorphisms (SNPs) in bovine AGPAT6 exons, and we analyzed 33 traits associated with meat quality and the carcass of Chinese Simmental cattle. SNP1 was significantly associated with back fat thickness and fat coverage rate. SNP2 was significantly associated with fat coverage rate and marbling score. Thus, the SNPs of AGPAT6 may be genetic factors influencing carcass composition of beef cattle.

A Bayesian and REML analyses were used on Tunisian dairy cattle data. Genetic parameters for 305-day milk, fat, and protein yields were estimated. Heritability estimates by using Bayesian method ranged from 0.187 to 0.273, and slightly higher than the corresponding REML. Large genetic correlations (> 0.88) among milk, fat, and protein yields were found for the two methods. This study suggests that results from both methods were reasonably similar to suggest both methods can be used.

Genetic parameters for 11 456 Tunisian Holstein cows were estimated for the following five reproductive traits: calving interval (CI), calving to first service interval, calving to conception interval (CCI), first service to conception interval and number of services per conception. Low heritabilities were estimated for these traits, and genetic correlation estimates between them were moderately high. The CCI–CI genetic correlation was 0.85, indicating that they are the same trait genetically.

Estimated breeding values (EBVs), relative breeding values (RBVs), and daughter yield deviations of Holstein cows with exceptional longevity (more than nine lactations completed) and the RBVs of their sires were analyzed. Exceptional cows had on average significantly lower EBVs for yield traits but significantly higher RBVs for somatic cell score (RZS) and functional longevity (RZN). Correlations among the proportion of exceptional cows per sire and RZN, RZS as well as fitness were positive.

Short summary
The lactation curve and lactation survival are important in dairy cattle breeding. Their simultaneous improvement results in economic benefits. The genetic relationship between the lactation survival and the lactation curve shape traits of milk yield and fat and protein percentages using information from of 25 981 primiparous Tunisian Holsteins was investigated. Cows that had higher persistencies for fat and protein percentages were more likely not to survive.
